Referring to FIG. 1, an electronic device 10, according to various embodiments of the present disclosure, is provided. The electronic device 10 includes a housing 11, a display installed within the housing 11, and one or more components installed adjacent to a periphery of the display. The housing 11 may have a first surface that faces a first direction (the front side), and a second surface that faces a second direction, opposite to the first direction.
The display includes a display substrate 20, and the display substrate 20 includes a first surface (front surface) on which contents (for example, images, texts, and videos) are displayed and a second surface (rear surface) situated on a side opposite to the first surface. The first surface (front surface) of the display substrate 20 may be classified into a screen area 21 for display and a peripheral area 22 that surrounds the screen area 21. The peripheral area 22 may be formed by a black matrix.
The screen area 21 of the display substrate 20 has a first side 21a having a first length, a second side 21b that extends from one end of the first side 21a in a direction perpendicular to the first side 21a, a third side 21c that extends from one end of the second side 21b in a direction perpendicular to the second side 21b, and a fourth side 21d that extends from one end of the third side 21c in a direction perpendicular to the third side 21c. The second side 21b has a second length longer than the first length, the fourth side 21d has the same second length as that of the second side 21b, and the third side 21c has the same first length as that of the first side 21a. A curved surface may be formed in the vicinity of the second side 21b and/or the fourth side 21d. The display substrate 20 may include various panels, such as a liquid crystal display (LCD) panel, a light-emitting diode (LED) panel, and an organic light-emitting diode (OLED) panel, which have an upper plate and a lower plate.
A window 12, that is a first plate that covers the display substrate 20, is mounted on a first surface of the housing 11, and the window 12 exposes contents to the outside while protecting the first surface of the display substrate 20.
A second plate (a rear plate) is provided on the second surface of the housing 11, and the second plate may be integrally formed on the second surface of the housing 11 or may be separately manufactured to be mounted on the second surface of the housing 11.
The window 12 has a display area 12a that exposes contents of the display substrate 20, and a non-display area 12b that interrupts visibility from the outside. The display area 12a of the window 12 may cover the screen area 21 of the display substrate 20, and the non-display area 12b of the window 12 may cover the peripheral area 22 of the display substrate 20.
In the electronic device 10, a plurality of bezels B1, B2, B3, and B4 may be formed at a periphery of the electronic device 10 as the peripheral area 22 of the display substrate 20 is covered by the non-display area 12b of the window 12. The plurality of bezels B1, B2, B3, and B4 includes a first bezel B1 arranged at an upper periphery of the display substrate 20, a second bezel B2 arranged at a left periphery of the display substrate 20, a third bezel B3 arranged at a lower periphery of the display substrate 20, and a fourth bezel B4 arranged at a right periphery of the display substrate 20. The first bezel B1 may be situated at the first side 21a of the screen area 21, the second bezel B2 may be situated at a second side 21b of the screen area 21, the third bezel B3 may be situated at a third side 21c of the screen area 21, and the fourth bezel B4 may be situated at a fourth side 21d of the screen area 21.
The widths of the plurality of bezels B1, B2, B3, and B4 may be the same or similar, or may be different according to the specification of the product. In particular, the width of the bezel in which the component 30 is installed may be the widest of the plurality of bezels B1, B2, B3, and B4. For example, in the case of a mobile device, a component 30, such as a camera, a receiver, a sensor, or a button, which performs various is functions, may be installed on the upper side of the electronic device 10 on the first bezel B1, for convenience of use, and the width of the first bezel B1 in which the component 30 is installed may be formed widest.
Although FIG. 1 illustrates a component 30, such as a camera, a sensor, a receiver, or a button, installed in an upper periphery of the display substrate 20, that is, in the first bezel B1, the component 30 may be installed in the second bezel B2, the third bezel B3, and the fourth bezel B4.
FIG. 2 illustrates an electronic device and a partially cutaway perspective view of the electronic device, according to an embodiment of the present disclosure. FIG. 3 is a perspective view illustrating a modified embodiment of FIG. 2, according to an embodiment of the present disclosure. FIG. 4 is a partially cutaway plan view of an electronic device, according to an embodiment of the present disclosure. FIG. 5 is a view illustrating a modified embodiment of FIG. 4, according to an embodiment of the present disclosure.
Referring to FIGS. 2 to 5, the electronic device 11 having a connector is shown. The connector may be a flexible printed circuit board (FPCB) 40 that transmits a driving signal of the display substrate 20 and may be connected to an electrode pattern formed in the peripheral area 22 on one side of the display substrate 20. The display substrate 20 is electrically connected to a main board through the flexible printed circuit board 40, and the display substrate 20 may be formed with a plate of a glass or plastic material.
As illustrated in FIG. 4, a driver IC 55 may be mounted on one side of the display substrate 20, and according to another configuration, the driver IC 55 may be mounted on one side of the flexible printed circuit board 40 that is a connector.
FIG. 6 is a sectional view taken along line A-A of FIG. 4, according to an embodiment of the present disclosure.
Referring to FIG. 6 a sectional view taken along line A-A of FIG. 4 is shown. A periphery of one side of the flexible printed circuit board 40 may be bonded to a peripheral area 22 of one side of the display substrate 20 by a conductive bonding layer 50, and accordingly, the flexible printed circuit board 40 may be electrically connected to the driver IC 55 of the display substrate 20.
FIG. 7 is a flowchart of a method for assembling an electronic device, according to an embodiment of the present disclosure. FIG. 8 is a plan view illustrating a state before a display substrate and a flexible printed circuit board (FPCB) of an electronic device are bonded to each other, according to an embodiment of the present disclosure. FIG. 9 is a sectional view taken along line B-B of FIG. 8, according to an embodiment of the present disclosure. FIG. 10 is a plan view illustrating a state in which a display substrate and an FPCB of an electronic device are bonded to each other, according to an embodiment of the present disclosure. FIG. 11 is a sectional view taken along line C-C of FIG. 10, according to an embodiment of the present disclosure. FIG. 12 is a plan view illustrating first and second cutting parts formed at a portion at which a display substrate and a FPCB of an electronic device are bonded to each other, according to an embodiment of the present disclosure. FIG. 13 is a sectional view taken along line D-D of FIG. 12, according to an embodiment of the present disclosure.
Referring to FIGS. 9, 11, and 13, the display substrate 20 has a first surface 26 that is parallel to a first plate 12 (a window) of the housing 11, a second surface 27 that is parallel to a second plate of the housing 11, and a third surface 25 that is disposed to be substantially perpendicular to the first surface 26. The first surface 26 may face the first direction of the housing 11, the second surface 27 may face the second direction of the housing 11, and the third surface may face the third direction perpendicular to the first to direction of the housing 11.
As shown in FIG. 13, the flexible printed circuit board 40 has a first part 46 disposed on the first surface 26 of the display substrate 20, a second part 47 disposed on the second surface 27 of the display substrate 20, and a third part 45 that extends from the first part 46 to the second part 47. The third part 45 may be formed to cover a portion of the third surface 25 of the display substrate 20.
Referring to FIG. 7, in step S1, the first part 46 of the flexible printed circuit board 40 may be bonded to a periphery of the first surface 26 of the display substrate 20.
According to an embodiment, the bonding layer 50 may be an anisotropic conductive film (ACF). Because the bonding layer 50 is pressed after being interposed between an electrode pattern provided at a periphery of one side of the flexible printed circuit board 40 and an electrode pattern provided at a periphery of one side of the display substrate 20, the flexible printed circuit board 40 and the display substrate 20 may be physically bonded and electrically connected to each other very firmly.
As shown in FIG. 12, a recess for accommodating the component 30 may be formed at a portion at which the display substrate 20 and the flexible printed circuit board 40 are bonded to each other by the bonding layer 50.
Referring to FIG. 7, in step S2, the recess may be formed by cutting a first cutting part 110 of the display substrate 20 and a second cutting part 120 of the flexible printed circuit board 40 at the same time. The first and second cutting parts 110 and 120 may be cut by a pinnacle die having an embossed cutting blade, or may be cut through a pulse-width modulation (PWM) control method of a laser. The first cutting part 110 may be formed in the peripheral area 22 corresponding to a periphery of one side of the display substrate 20. The second cutting part 120 may be formed at a periphery of one side of the flexible printed circuit board 40 that is bonded to the display substrate 20.
The size and shape of the first cutting part 110 and the second cutting part 120 may correspond to each other partially or entirely according to the shape or size of the component 30. For example, when the size of the component 30 is relatively large, as in FIG. 3, the size and shape of the first cutting part 110 and the second cutting part 120 may partially correspond to each other, and when the size of the component 30 is relatively small, the size and shape of the first cutting part 110 and the second cutting part 120 may entirely correspond to each other. The first and second cutting parts 110 and 120 may have a structure corresponding to an external shape of the component 30 entirely or partially. For example, when the outer contour of the component 30 is circular, the first and second cutting parts 110 and 120 may have a circular or “U”-shaped structure, and when the outer contour of the component 30 is tetragonal, the first and second cutting parts 110 and 120 may have a rectangular shape.
When the first cutting part 110 and the second cutting part 120 are bonded to each other after being individually formed when they are bonded through ACF bonding, the first cutting part 110 and the second cutting part 120 do not agree with each other along the accommodation direction of the component 30 due to thermal deformation so that an alignment thereof is not precisely made, an increase of bezels cannot be prevented and an inferior product may be produced because the component 30 cannot be stably accommodated in the first and second cutting parts 110 and 120.
Because the first and second cutting parts 110 and 120 are formed at the same time at a portion at which the display substrate 20 and the flexible printed circuit board 40 are bonded to each other by the bonding layer 50, at least at portions of the first cutting part 110 and the second cutting part 120 are aligned along the accommodation direction (cutting direction) of a component. Accordingly, an alignment thereof may be precise, and thus in step S3 of FIG. 7, the component 30 may be stably accommodated in the first cutting part 110 and the second cutting part 120, as illustrated in FIG. 2.
In this way, because the first cutting part 110 and the second cutting part 120 are formed at the same time while the display substrate 20 and the flexible printed circuit board 40 are bonded to each other, an accommodation space, into which at least a portion of the component 30 may be inserted from a periphery of one side of the display substrate 20, may be sufficiently secured. Accordingly, the width of the first bezel B1 due to the components 30 installed adjacent to a periphery of the display substrate 20 may be reduced. For example, when the component 30 is a camera, at least a portion of the component 30 is inserted into an inside of a periphery of the display substrate 20 by the first and second cutting parts 110 and 120, even when the size of the camera is large due to an increase of the specification of the camera, so that an increase in the width of the first bezel B1 can be prevented or the width of the bezel B1 can be reduced.
The sizes of the first and second cutting parts 110 and 120 may be larger than the size of the component 30 so that the component 30 accommodated in the first and second cutting parts 110 and 120 may be prevented from contacting the cut surfaces of the first and second cutting parts 110 and 120.
As shown in FIGS. 8, 10, and 12, an electrode part 41 and a non-electrode part 42 may be formed at a periphery of one side of the flexible printed circuit board 40. The electrode part 41 may be an area in which an electrode pattern such as one or more conductive patterns or a conductive line is formed, such that signals are transmitted and received between the driver IC 55 and the display substrate 20. The electrode part 41 may extend from the first part 46 of the flexible printed circuit board 40 via the third part 45.
The non-electrode part 42 may be an area in which an electrode pattern is not formed such that a signal is not transmitted and received between the driver IC 55 and the display substrate 20. The recessed second cutting part 120 may be formed in the non-electrode part 42. In detail, the flexible printed circuit board 40 may have a first non-conductive layer that faces the first direction of the housing 11, a second non-conductive layer that faces the second direction of the housing 11, and a metal pad or metal pattern disposed between the first non-conductive layer and the second non-conductive layer. Here, the first non-conductive layer and the second non-conductive layer may correspond to the non-electrode part 42, and the metal pad or metal pattern may correspond to the to electrode part 41. The metal pad or metal pattern may be arranged along at least one periphery of the first and second cutting parts 110 and 120. Further, the metal pad or metal pattern may be electrically isolated by the non-electrode part 42 that corresponds to the first and second non-conductive layers.
As illustrated in FIGS. 8 to 13, a plurality of via holes 43 may be formed in advance before the second cutting part 120 is formed in the non-electrode part 42. The first and second cutting parts 110 and 120 may be formed precisely and easily through the plurality of via holes 43. Because the first and second cutting parts 110 and 120 are formed through the plurality of via holes 43, a plurality of channels or troughs may be formed at a periphery of the first and second cutting parts 110 and 120 as one or more via holes 43 cross the cut surface of the second cutting part 120, as illustrated in FIGS. 3 and 5. Accordingly, the cut surface formed along the first and second cutting parts 110 and 120 of the first pat 46 and the second part 47 of the flexible printed circuit board 40 may have a plurality of channels or troughs. The cut surface formed along the first and second cutting parts 110 and 120 of the third part 45 of the flexible printed circuit board 40 may have a plurality of channels or troughs.
Further, a dummy pattern 44 may be formed at an outer side of the non-electrode part 42. The dummy pattern 44 may extend along at least a portion of the non-electrode part 42 and/or the second cutting part 120, as shown in FIG. 4. The dummy pattern 44 may have a structure that surrounds the non-electrode part 42 and/or the second cutting part 120, as shown in FIG. 5. The dummy pattern 44 is a pattern that is electrically short-circuited from the display substrate 20 and/or the connector 40. The dummy pattern 44 may be formed to be separated from a periphery of the second cutting part 120 by a spacing gap s. Because the dummy pattern 44 has a width t, the vulnerable strength of the flexible printed circuit board 40 due to the formation of the second cutting part 120 maybe reinforced. For example, the spacing gap s between the dummy pattern 44 and the second cutting part 120 may be approximately 0.7 mm, and the width t of the dummy pattern 44 may be approximately 0.3 mm to 0.8 mm.
Further, as shown in FIG. 6, a cover member 60 that covers the display substrate 20 and the flexible printed circuit board 40, which is a connector, may be installed on the front surface of the display substrate 20. A third cutting part 130 corresponding to the first and second cutting parts 110 and 120 may be formed in the cover member 60, and accordingly, the component 30 may be stably accommodated within the first cutting part 110, the second cutting part 120, and the third cutting part 130.
According to an embodiment, the cover member 60 may be a touch screen panel (TSP) that performs a touch screen function for the display substrate 20. A touch screen driving circuit board 63 may be connected to a periphery of one side of the touch screen panel 60. A third cutting part 130 corresponding to the first and second cutting parts 110 and 120 may be formed in the touch screen panel 60 and the touch screen driving circuit board 63, and at least a portion of the component 30 may be accommodated in the third cutting part 130.
According to another embodiment, the cover member 60 may be a protective film for protecting the display substrate 20 and the flexible printed circuit board 40 that is a connector. The third cutting part 130 may be formed at a periphery of one side of the protective film.
Referring to FIGS. 8 to 13, a scheduled area in which the first cutting part 110 of the display substrate 20 and the second cutting part 120 of the flexible printed circuit board 40 may be set. That is, wrong positioning of the first and second cutting parts 110 and 120 may be prevented when the first and second cutting parts 110 and 120 are formed, by presetting the formation locations of the first and second cutting parts 110 and 120 at a portion at which the display substrate 20 and the flexible printed circuit 40 overlap each other and then are bonded to each other.
As illustrated in FIGS. 8 and 9, a plurality of via holes 43 may be machined in advance at a portion at which the display substrate 20 and the flexible printed circuit board 40 overlap each other.
The plurality of via holes 43 may be formed in the non-electrode part 42 of the flexible printed circuit board 40. The first and second cutting parts 110 and 120 may be formed more easily through the plurality of via holes 43.
As illustrated in FIGS. 10 and 11, after the via holes 43 are machined, a periphery of one side of the first surface of the display substrate 20 and the first part 40 of the flexible printed circuit board 40 may be bonded to each other by the bonding layer 50. Here, FIG. 11 is a sectional view taken along line C-C of FIG. 10.
According to an embodiment, the bonding layer 50 may be an ACF. Because the bonding layer 50 is pressed upwards and downwards after being interposed between an electrode pattern provided at a periphery of one side of the flexible printed circuit board 40 and an electrode pattern provided at a periphery of one side of the display substrate 20, the first part 46 of the flexible printed circuit board 40 and the first surface 26 of the display substrate 20 may be physically bonded and electrically connected to each other.
Thereafter, as illustrated in FIGS. 12 and 13, as the flexible printed circuit board 40 is bent from the first surface 26 of the display substrate 20 towards the second surface 27 of the display substrate 20 with respect to the bonding layer 50, the third part 45 of the flexible printed circuit board 40 may cover at least a portion of the third surface 25 of the display substrate 20 and the second part 47 of the flexible printed circuit board 40 may be arranged on the second surface 27 of the display substrate 20. In this state, the first and second cutting parts 110 and 120 for accommodating the component 30 may be formed at the same time. According to an embodiment, the first and second cutting parts 110 and 120 may be formed by cutting the portions at which the display substrate 20 and the flexible printed circuit board 40 are bonded to each other at the same time with a cutting tool such as a pinnacle die having an embossed cutting blade. According to another embodiment, the first and second cutting parts 110 and 120 may be formed by cutting the portions at which the display substrate 20 and the FPCB 40 overlap each other at the same time through irradiation of a laser beam of a laser device that is driven in a PWM control method. In particular, the display substrate 20 and/or the flexible printed circuit board 40 may be burned or deformed by heat when a laser beam irradiated by the laser device is of high power, the formation precision of the first and second cutting parts 110 and 120 may be improved by irradiating the laser beam under a PWM output control to lower the laser device to a low electric power by which deformation due to heat is not generated.
When the first and second cutting parts 110 and 120 are formed, the display substrate 20 is mounted in the housing 11, and other components may be mounted while the component 30 is accommodated in the first and second cutting parts 110 and 120. Thereafter, the cover member 60 having the third cutting part 130 corresponding to the first and second cutting parts 110 and 120 may be installed on the front surface of the display substrate 20, and then the window 12 may be installed on the front surface of the cover member 60.
FIG. 20 is a sectional view illustrating a state in which a component is accommodated in a first cutting part and a second cutting part of an electronic device, according to an embodiment of the present disclosure.
Referring to FIG. 20, an electrode pattern may be formed in a peripheral area 22 of one side of the display substrate 20. A first connector, i.e., the flexible printed circuit board 40, and a second connector 80 that transmits a driving signal of the display substrate 20 may be connected to an electrode pattern of the display substrate 20, and the display substrate 20 may be electrically connected to a main board through the flexible printed circuit board 40 and the second connector 80.
The second connector 80 has a property different from that of the flexible printed circuit board 40. According to an embodiment, the second connector 80 may include at least one of a chip on film (COF) and a tape carrier package (TCP). The second connector 80 may be bonded to or integrally formed with one side of the flexible printed circuit board 40. Because the second connector 80 is formed of a material that is more flexible than that of the flexible printed circuit board 40 or is thinner than the flexible printed circuit board 40, it may be bent more smoothly. The second connector 80 is bonded to a periphery of the peripheral area 22 of one side of the display substrate 20 by the bonding layer 50, and accordingly, the second connector 80 may be electrically connected to the main board (not illustrated) through the flexible printed circuit board 40.
FIG. 18 is a plan view illustrating a first and second cutting parts are formed at a portion at which a display substrate and a chip on film (COF) of an electronic device are bonded to each other, according to an embodiment of the present disclosure. FIG. 19 is a sectional view taken along line G-G of FIG. 18, according to an embodiment of the present disclosure.
Referring to FIGS. 18 and 19, the second connector 80 has a first part 86 arranged on the first surface 26 of the display substrate 20, a second part 87 arranged on the second surface 27 of the display substrate 20, and a third part 85 that extends from the first part 86 to the second part 87, as illustrated in FIG. 19. The third part 85 may be formed to cover at least a portion of the third surface 25 of the display substrate 20. The first part 86 of the second connector 80 may be bonded to a periphery of the first surface 20 of the display substrate 20.
Because the flexible printed circuit board 40 and the second connector 80 includes a driver IC 55, the display substrate 20 may have an unbreakable plate including a substrate of a flexible material, such as a synthetic resin. In this way, the driver IC 55 may not be mounted on the display substrate 20 having the unbreakable plate.
According to an embodiment, the bonding layer 50 is an ACF, and because the bonding layer 50 is pressed after being interposed between an electrode pattern provided at a periphery of one side of the second connector 80 and an electrode pattern provided at a periphery of one side of the display substrate 20, the second connector 80 and the display substrate 20 may be physically bonded or electrically connected to each other very firmly.
Further, a recess for accommodating the component 30 may be formed at a portion at which the display substrate 20 and the second connector 80 are bonded to each other by the bonding layer 50. The recess may be formed by cutting the first and second cutting part 110 and 120 at the same time. The first and second cutting parts 110 and 120 may be cut by a pinnacle die having an embossed cutting blade, or may be cut through a PWM control method of a laser.
The first cutting part 110 may be formed in a peripheral area 22 of the display substrate 20. The second cutting part 120 may be formed at a periphery of one side of the second connector 80 that is bonded to the display substrate 20.
The size and shape of the first cutting part 110 and the second cutting part 120 may correspond to each other partially or entirely according to the shape or size of the component 30. For example, when the size of the component 30 is relatively large, as shown in FIG. 6, the size and shape of the first cutting part 110 and the second cutting part 120 may partially correspond to each other, and when the size of the component 30 is relatively small, the size and shape of the first cutting part 110 and the second cutting part 120 may entirely correspond to each other. Further, the first and second cutting parts 110 and 120 may have a structure corresponding to an external shape of the component 30 entirely or partially. For example, when the outer contour of the component 30 is circular, the first and second cutting parts 110 and 120 may have a circular or “U”-shaped structure, and when the outer contour of the component 30 is tetragonal, the first and second cutting parts 110 and 120 may have a rectangular shape.
When the first cutting part 110 and the second cutting part 120 are bonded to each other through ACF bonding after being individually formed, so that an alignment of the first cutting part 110 and the second cutting part 120 is not precisely made, an increase of the width of a bezel cannot be prevented and an inferior product may be produced because the component 30 cannot be stably accommodated in the first and second cutting parts 110 and 120. In this regard, because the first and second cutting parts 110 and 120 are formed at a portion at which the display substrate 20 and the second connector 80 are bonded to each other by the bonding layer 50 at the same time, at least portions of the first cutting part 110 and the second cutting part 120 agree with each other or are aligned along the accommodation direction (cutting direction) of the component 30, and accordingly, the component 30 may be stably accommodated in the first cutting part 110 and the second cutting part 120 as illustrated in FIG. 20.
In this way, because the first cutting part 110 and the second cutting part 120 are formed at the same time while the display substrate 20 and the second connector 80 are bonded to each other, a sufficient accommodation space into which at least a portion of the component 30 may be inserted from a periphery of one side of the display substrate 20 may be secured. Accordingly, the width of the first bezel B1 due to the components 30 installed adjacent to a periphery of the display substrate 20 may be reduced. For example, when the component 30 is a camera, at least a portion of the component 30 is inserted into an inside of a periphery of the display substrate 20 by the first and second cutting parts 110 and 120 even when the size of the camera is large due to an increase of the specification of the camera so that an increase in the width of the first bezel B1 can be prevented or the width of the first bezel B1 can be reduced, and accordingly, the degree of freedom of design of the electronic device 10 may be increased, making it possible to increase a competitiveness of the product.
Further, the sizes of the first and second cutting parts 110 and 120 may be larger than the size of the component 30 so that the component 30 accommodated in the first and second cutting parts 110 and 120 may be prevented from contacting the cut surfaces of the first and second cutting parts 110 and 120.
Referring to FIGS. 18 and 20, an electrode part 81 and a non-electrode part 82 are formed at a periphery of one side of the second connector 80. The electrode part 81 is an area in which an electrode pattern such as at least one conductive pattern or a conductive line is formed such that a signal may be transmitted and received between the driver IC 55 and the display substrate 20, and the electrode part 81 may extend from the first part 86 of the second connector 80 via the third part 85. The non-electrode part 82 is an area in which an electrode pattern is not formed such that a signal is not transmitted and received between the driver IC 55 and the display substrate 20, and the second cutting part 120 may be formed in the non-electrode part 82.
FIG. 14 is a plan view illustrating a state before a display substrate and a chip on film (COF) of an electronic device is bonded to each other, according to an embodiment of the present disclosure. FIG. 15 is a sectional view taken along line E-E of FIG. 14, according to an embodiment of the present disclosure. FIG. 16 is a plan view illustrating a state in which a display substrate and a chip on film (COF) of an electronic device are bonded to each other, according to an embodiment of the present disclosure. FIG. 17 is a sectional view taken along line F-F of FIG. 16, according to an embodiment of the present disclosure.
Referring to FIGS. 14 to 17 and referring back to FIGS. 18 and 19, a process of assembling an electronic device is illustrated. As shown in FIGS. 14 to 19, a plurality of second via holes 83 may be formed in advance before the second cutting part 120 is formed in the non-electrode part 82, and a plurality of first via holes 23 may be formed at a periphery of one side of the display substrate 20 corresponding to the second via holes 83 of the second connector 80.
The first and second cutting parts 110 and 120 may be formed precisely and easily through the plurality of first and second via holes 23 and 83. As shown in FIG. 18, because the first and second cutting parts 110 and 120 are formed through the plurality of first and second via holes 23 and 43, a plurality of channels or troughs may be formed at a periphery of the second cutting part 120 as one or more first and second via holes 23 and 83 cross the cut surface of the first and second cutting part 110 and 120. The cut surface formed along the first and second cutting parts 110 and 120 of the first pat 86 and to the second part 87 of the second connector 80 may have a plurality of channels or troughs. The cut surface formed along the first and second cutting parts 110 and 120 of the third part 85 of the second connector 80 may have a plurality of channels or troughs.
Further, a dummy pattern 84 may be formed at an outer side of the non-electrode part 82, and the dummy pattern 84 may extend along a peripheral portion of the non-electrode part 82 and/or the second cutting part 120 or surround a periphery of the non-electrode part 82 and/or the second cutting part 120. In particular, the dummy pattern 84 may be spaced apart from a periphery of the second cutting part 120 by a space gap s, and because the dummy pattern 84 has a width t, the vulnerable strength of the second connector 80 may be reinforced due to the formation of the second cutting part 120. For example, as shown in FIG. 20, the spacing gap s between the dummy pattern 84 and the second cutting part 120 may be approximately 0.7 mm, and the width t of the dummy pattern 84 is approximately 0.3 mm to 0.8 mm.
Further, a cover member 60 that covers the display substrate 20 and the second connector 80 may be installed on the front surface of the display substrate 20. A third cutting part 130 corresponding to the first and second cutting parts 110 and 120 may be formed in the cover member 60, and accordingly, the component 30 may be stably accommodated within the first cutting part 110, the second cutting part 120, and the third cutting part 130.
Referring to FIGS. 14 to 19, a scheduled area in which the first cutting part 110 of the display substrate 20 and the second cutting part 120 of the second connector 80 is set. That is, wrong positioning of the first and second cutting parts 110 and 120 may be prevented when the first and second cutting parts 110 and 120 are formed, by presetting the formation locations of the first and second cutting parts 110 and 120 at a portion at which the display substrate 20 and the second connector 80 overlap each other and then are bonded to each other.
As illustrated in FIGS. 14 and 15, a plurality of first via holes 23 and a plurality of second via holes 83 are machined to correspond to each other, at a portion at which the display substrate 20 and the second connector 80 overlap each other and are bonded to each other. The plurality of first via holes 23 may be formed in a peripheral area 22 of one side of the display substrate 20, and the plurality of second via holes 83 may be formed in the non-electrode part 82 of the second connector 80. The first and second cutting parts 110 and 120 may be formed more easily through the plurality of first via holes 23 and the plurality of second via holes 83.
As illustrated in FIGS. 16 and 17, after the via holes 23 and 83 are machined, a periphery of one side of the display substrate 20 and a periphery of one side of the second connector 80 may be bonded to each other by the bonding layer 50.
According to an embodiment, the bonding layer 50 is an ACF, and because the bonding layer 50 is pressed after being interposed between an electrode pattern provided at a periphery of one side of the second connector 80 and an electrode pattern provided at a periphery of one side of the display substrate 20, the first part 86 of the second connector 80 and the first surface 26 of the display substrate 20 may be physically bonded or electrically connected to each other.
Thereafter, as in FIGS. 18 and 19, as the second connector 80 is bent from the first surface 26 of the display substrate 20 towards the second surface 27 of the display substrate 20 with respect to the bonding layer 50, the third part 85 of the second connector 80 may cover at least a portion of the third surface 25 of the display substrate 20 and the second surface 87 of the second connector 80 may be arranged on the second surface 27 of the display substrate 20. In this state, the first and second cutting parts 110 and 120 for accommodating the component 30 may be formed at the same time.
According to an embodiment, the first and second cutting parts 110 and 120 may be formed by cutting the portions at which the display substrate 20 and the second connector 80 are bonded to each other at the same time with a cutting tool such as a pinnacle die having an embossed cutting blade. According to another embodiment, the first and second cutting parts 110 and 120 may be formed by cutting the portions at which the display substrate 20 and the second connector 80 are bonded to each other at the same time through irradiation of a laser beam of a laser device driven in a PWM control method. Because the display substrate 20 and/or the second connector 80 may be burned or deformed by heat when a laser beam irradiated by the laser device is of high power, the formation precision of the first and second cutting parts 110 and 120 may be improved by irradiating the laser beam under a PWM output control to lower the lower of the laser device to a low electric power by which deformation due to heat is not generated.
When the first and second cutting parts 110 and 120 are formed, the display substrate 20 is mounted in the housing 11, and other components may be properly mounted while the component 30 is accommodated in the first and second cutting parts 110 and 120. The cover member 60 having the third cutting part 130 corresponding to the first and second cutting parts 110 and 120 may be installed on the front surface of the display substrate 20, and then the window 12 may be installed on the front surface of the cover member 60.
