FIG. 1 is a perspective view illustrating an example electronic device having a curved shape in accordance with aspects of the present disclosure.
Referring to FIG. 1, a display module 2 is installed at a front side of the electronic device 1, a speaker device 3 for receiving a counterpart's voice is installed over the display module 2, and a microphone device 6 for transmitting a user's voice to the counterpart is installed under the display module 2, thereby performing a basic communication function. In one example, an interface connector 7 for transmitting and receiving data to and from an external device in a wired manner or receiving external power for charging a battery pack is disposed at a side of the microphone device 6. It is understood that the electronic device is not limited to the above-described configuration. The microphone device 6 and the interface connector 7 may be disposed at various positions.
In one example, sensing electronic components for performing various functions of the electronic device 1 may be provided around the speaker device 3 of the electronic device 1. As for the components, a video call camera device 5 for video telephony (VT) with the counterpart may be mounted. In addition, a sensor device 4 may be mounted, which allows the electronic device 1 to operate adaptively according to a surrounding environment. The sensor device 4 may include an illumination sensor for detecting surrounding illumination and automatically adjusting brightness of a display according to the detected illumination, and/or a proximity sensor or infrared sensor for detecting proximity when being close to the user's head portion during call connection and deactivating the display module 2. In another example, at least one physical key button exposed through rear case frame 9 may be mounted on a side of the electronic device. In a further example, the key button may be used for a volume up/down button, a wake-up button, or a power on/off button. Although not illustrated, the electronic device may include various other mechanical structures mounted therein.
In one example, the display module 2 may have a curved shape with a predetermined curvature. In another example, the entire shape of the electronic device 1 may be curved according to the curved shape of the display module 2 such that the entire shape of the electronic device 1 has a curvature that is the same as or substantially similar to that of display module 2. In a further example, the display module 2 may be a touchscreen device having a region on which data input and output is performed. In this case, the display module 2 may be a touchscreen including both a liquid crystal display (LCD) module and a touch sensor panel. When the electronic device 1 includes a separate input object, such as a touch pen or a stylus pen for data input, the display module 2 may also include a sensor pad for detecting the object. The display module 2 may include a window for protecting the display module 2 which is mounted on the outer side of the electronic device 1.
In a further example, the curved display module 2 is used and the electronic components disposed under the display module 2 are disposed to have a slope with respect to a horizontal plane. As a result, this allows the electronic device to be slim even while being capable of performing various functions. Since the electronic device has the curved shape, grip feel may be improved. Therefore, the appearance of electronic device 1 may be more aesthetically pleasing than a conventional bar-type device; in turn, the appearance may make the device more competitive in the market and may make the device more desirable by users.
FIG. 2 is a configuration diagram illustrating an example arrangement of electronic components inside the electronic device of the present disclosure.
Referring to FIG. 2, the electronic device 1 includes a curved display module 2 (see FIG. 1) mounted at the front side thereof and a housing 22 that supports the display module 2 mounted at the upper portion thereof. The electronic device may further include a front case frame 8 mounted to surround the rim of the housing 22 and to form the side appearance of the electronic device 1. In another example, a plurality of electronic components may be disposed in the upper portion of the housing 22. In yet a further example, the electronic components may include at least one substrate 10, 20 or 30 and a battery pack 40. In a further example, the electronic components may be at least one of an interface connector 302, a camera module 12, a microphone module (not illustrated), an ear jack module 11, an antenna module (not illustrated), a speaker module 301, a vibrator device (not illustrated), a shield can for shielding (not illustrated), a socket for accommodating a card-type external device (211 of FIG. 6), and various sensor modules (not illustrated).
In one example, the at least one substrate 10, 20 or 30 may be disposed to have a slope with respect to a horizontal plane because of the curved display module 2. Therefore, it may be difficult to use a substrate, having an area that is similar or equal to the entire area of the electronic device, as a single component. In another example, the at least one substrate 10, 20 or 30 may include a main substrate disposed in the longitudinal direction at a side of the electronic device and at least one sub-substrate 20 or 30 detachably and electrically connected to the main substrate 10. As illustrated in FIG. 2, the sub-substrate 20 or 30 may be electrically connected to the main substrate 10 through a predetermined connector 201. It is understood that the present disclosure is not limited to the above configuration such that more than two sub-substrates may be disposed in the electronic device. In one example, the at least one substrate 10, 20 or 30 may be disposed in accordance with at least one of a -shaped arrangement, an inverse--shaped arrangement, a T-shaped arrangement, and an I-shaped arrangement. In another example, the at least one substrate 10, 20, and 30 may be arranged within proximity of battery 40. However, it is understood that the present disclosure is not limited to these arrangements. The at least one substrate 10, 20 or 30 may be disposed in various shapes depending on a curvature radius of the display module 2.
In a further example, the camera module 12 and the ear jack module 11 may be disposed on the upper portion of the electronic device 1, and the connector 302 and the speaker module 301 may be disposed on the lower portion of the electronic device 1. In a further example, the electronic components may be disposed in such a way as to be disposed accordingly on the main substrate 10 or the at least one sub-substrate 20 or 30. In yet a further example, the electronic components may be electrically connected to the above-described substrates 10, 20 and 30 even though the electronic components are disposed accordingly inside the electronic device rather than on the main substrate 10 or the at least one sub-substrate 20 or 30.
In a further example, the battery pack 40 may be disposed so as not to be disposed on at least one substrate 10, 20 or 30. The battery pack 40 may be disposed so as to be next to at least one substrate 10, 20 or 30 without overlapping. The substrate 10, 20 or 30 and the battery pack 40 may be disposed at different slopes and in different inclined directions.
FIG. 3 is a cross-sectional view illustrating an example main portion of an electronic device in which a display module with curvature is disposed. Although an arrangement relationship between a battery pack and a main substrate is described, the technical characteristics described below may be also applied to an arrangement relationship between the battery pack and at the least one sub-substrate.
Referring to FIG. 3, the main substrate 10 and the battery pack 40 may be disposed to have a slope with respect to a horizontal plane. As illustrated in FIG. 3, the main substrate 10 may be disposed to have a predetermined angle θ1 with respect to a horizontal plane. The substrate may be disposed to have a slope of about 5 degree when the curvature radius of the display module 2 is 400 R (radius). In another example, the battery pack 40 may be disposed to have an angle of θ2. In a further example, the battery pack 40 may be disposed to have a slope of about 1 degree when the curvature radius of the display module 2 is 400 R. However, these numerical values are merely illustrative, and the arrangement may be made to have various efficient slopes depending on the shape and mounting space of the electronic device 1.
In a further example, the main substrate 10 and the battery pack 40 may be disposed to have a slope corresponding to a straight line passing a tangent of the display module 2 that corresponds to the central lines thereof. The main substrate 10 and the battery pack 40 may be disposed to have various effective angles depending on the shape and mounting space of the electronic device 1.
In one example, the housing 22 supporting the display module 2 may include a first surface 221 in a direction adjacent to the display module 2 and a second surface 222 which faces the first surface and in which a plurality of electronic components may be mounted. In another example, the first surface 21 may be formed to have a curvature identical to that of the display module 2. This causes the rear surface of the display module 2 to be very close to the first surface of the housing 22, thereby maximizing spatial availability and preventing damage from external impact.
The second surface 222 of the housing 22 may be formed to have a curvature substantially identical to the first surface. In a further example, the second surface of the housing 22 may be formed to be substantially flat. In yet a further example, there may be provided at least one mounting portion in which the main substrate 10 and the battery pack 40 are mounted. In another example, there may be provided at least one mounting portion in which the main substrate 10 and the battery pack 40 are mounted.
In another example, when the main substrate 10 and the battery pack 40 are disposed alongside each other, a border portion (X of FIG. 3) between the battery pack 40 and the main substrate 10 may be defined as starting point from which the battery pack 40 and the main substrate 10 start to incline. In a further example, the battery pack 40 and the main substrate 10 may be disposed to have different slopes than that of the border portion.
FIGS. 4A and 4B are cross-sectional views of an example electronic device illustrating an arrangement of a substrate. FIGS. 4A and 4B illustrate that spatial availability may be improved, when the substrate is disposed to have a slope, rather than disposing the substrate parallel to the plane.
When the overall length of the main substrate 10 is d2 as illustrated in FIG. 4B, a portion is cased to be Therefore, the main substrate 10 may be disposed to have a slope as illustrated in FIG. 4B. When the overall length d4 of the battery pack 40 is 19.7 mm, and the battery pack 40 is disposed to have a slope with respect to a plane, spatial availability of 3.5 mm may be further obtained in a same mounting condition, thereby improving a space by 21%. Therefore, larger electronic components may be mounted under the same mounting condition.
FIGS. 5A and 5B are example cross-sectional views of an example electronic device illustrating an arrangement of a substrate. FIGS. 5A and 5B illustrates that spatial availability may be improved when a battery pack is disposed to have a slope rather than being disposed parallel to a plane.
When the overall length of the battery pack 40 is d4 as illustrated in FIG. 5A, a portion corresponding to a length of d3 may be wasted space. Therefore, the main substrate 10 may be disposed to have a slope as illustrated in FIG. 5B, thereby allowing the battery pack 40 to have the overall length of d4. In one example, when the overall length d4 of the battery pack 40 is 45 mm and the battery pack 40 is disposed to have a slope with respect to a plane, spatial availability of 5.2 mm may be further obtained in a same mounting condition, thereby improving a space by 13%. Therefore, a battery pack having a larger capability may be used under the same spacing or casing conditions.
FIG. 6 is an example configuration diagram of an example sub-substrate. A second sub-substrate may have a technical configuration identical or similar to that of the substrate shown in FIG. 6.
Referring to FIG. 6, the sub-substrate 20 may include a first connection substrate 210 which is electrically connected to the main substrate 10, and a second connection substrate 220 and a third connection substrate 230 which is electrically connected to the first connection substrate 210 at different positions. The first, second, and third connection substrates 210, 220 and 230 may be formed of rigid material and be connected to one another through an electrical connection portion 202 which may be flexible. Therefore, the respective connection substrates 210, 220 and 230 may be configured to be movable to one another. This may be advantageous when the substrates 210, 220 and 230 are in an electronic device with a curved display module 2. The respective connection substrates 210, 220 and 230 may be disposed to have different slopes. A flexible printed circuit (FPC) may be used as the flexible electric connection portion 202.
In one example, the connector 201 for electrically connecting to the main substrate 10 is electrically and movably connected to the first connection substrate 210 by a flexible printed circuit depending on a distance from the main substrate 10. Various electronic components may be mounted in each of the connection substrates 210, 220 and 230. A socket 211 for selectively connecting a card-type external device may be mounted in the first connection substrate 210. The antenna module (see FIG. 7) may be mounted in the second connection substrate 220. A key button device (see FIG. 8) may be mounted in the third connection substrate.
In a further example, the respective connection substrates 210, 220 and 230 may be connected to one another and, at the same time, may be disposed to have different slopes, thereby enabling effective mounting of the above-described electronic components.
FIG. 7 is a diagram illustrating an example configuration in which an antenna module is disposed in a sub-substrate. Referring to FIG. 7, the antenna module 221 may be mounted on the second connection substrate 220 of the second sub-substrate 20. The radiation efficiency of an antenna radiator of the antenna module 221 may be proportional to its distance from the substrate. Therefore, the radiation efficiency increases as the antenna module 221 is farther from the substrate.
In a further example, the second connection substrate 220 may have a height d5 that is substantially identical to that of the first connection substrate 210, as illustrated in FIG. 7. In this instance, the second connection substrate 220 may be distanced further from rear case frame 9, by a distance of d6, which is further than the distance between the first connection substrate 210 and rear case frame 9. Therefore, the antenna module 221 mounted on the second connection substrate 220 may be further distanced from the substrate by a length of d6−d5. A separate antenna carrier may be mounted to provide a distance between the second connection substrate 220 and the antenna radiator. The antenna carrier may be mounted at a height that increases by the length of d6−d5, thereby improving radiation efficiency.
FIG. 8 is a diagram of an example structure in which a tack switch for key button manipulation is disposed in a sub-substrate. FIG. 8 is an enlarged example configuration diagram of a portion A of FIG. 7.
Referring to FIG. 8, the third connection substrate 230 may be disposed to have a slope at an angle of θ3 with respect to a plane by the flexible printed circuit. This configuration may have a z-axis mounting height that is less than that of an existing key button device employing a metal dome. The decreased z-axis mounting height of this configuration may be accomplished by using a flexible printed circuit board (FPCB) and may prevent generation of a hole through additional coring of the support bracket 232. The above configuration may be beneficial upon an immersion test for the electronic device. In a further example, a tact switch 231 may be used as a switching device. Tact switch 231 may be mounted in the third connection substrate 230 and may operate in interlocking with the pressing operation of a key button 233. Key button 233 may be mounted such that at least a portion of the key button 233 is exposed to the outside of the electronic device 1.
FIGS. 9A and 9B are diagrams illustrating an example structure in which a speaker sound emission hole is disposed in a case frame. FIG. 9A is a diagram illustrating an example electronic device having a flat rear case frame and FIG. 9B is a diagram illustrating an example electronic device having a rear case frame with a curvature.
Referring to FIG. 9A, a speaker sound emission hole 901 for emitting speaker sound generated by a speaker module may be formed in the rear case frame 9 of the electronic device 1. When the electronic device 1 is placed on a floor, the surface of the rear case frame 9 formed to be flat is closely in contact with the floor to close the speaker sound emission hole 901, thereby preventing speaker sound from being emitted smoothly. Therefore, it may be necessary to form a support that projects upward around the speaker sound emission hole 901, which may not be aesthetically pleasing.
Referring to the example of FIG. 9B, the rear case frame 9 of the electronic device 1 is formed in a curved shape, the left and right sides of which are upwardly curved. In this instance, the speaker sound emission hole 91 may be formed on a curved portion. Therefore, even when the electronic device 1 is placed on the floor, the speaker sound emission hole 91 is not in close contact with the floor due to the shape of the curved rear case frame 9. In turn, speaker sound may be emitted toward the outside even without a separate support projection. The electronic device 1 includes no separate support projection, making the appearance of the electronic device 1 more aesthetically pleasing.
FIG. 10 is a diagram illustrating an example arrangement relationship between a display module and an ear jack module. Referring to FIG. 10, the display module 2 may be a touchscreen device. In a further example, the display module 2 may be formed in such a way that a LCD module 23 and a touch sensor pad 24 are mounted in a layered structure, and may include a foldable driver IC substrate 25 for an LCD Driver IC (LDI) area. In a further example, the driver IC substrate 25 may be mounted in a state of being folded to the rear surface of the display by the flexible printed circuit (FPC) 26. In the electronic device 1, the ear jack module 11 may be mounted in the same plane as the driver IC substrate 25. When the ear jack module 11 is disposed at a position that does not overlap the driver IC substrate 25, interference between the ear jack module 11 and the driver IC substrate 25 may occur or the volume of the electronic device 1 may increase.
In one example, the ear jack module 11 may be disposed at a position that does not overlap the driver IC substrate 25 of the display module. The driver IC substrate 25 and the ear jack module 11 may be disposed opposite to each other as illustrated in FIG. 10. However, it is understood that the example of FIG. 10 is not limited to the above-described configuration, and that the ear jack module 11 may be disposed at various positions that do not overlap driver IC substrate 25 of the display module.
FIGS. 11A and 11B are diagrams illustrating example structural arrangements of a bushing for supporting a substrate. FIGS. 11A and 11B also illustrate a sleeve for screw engagement.
Referring to FIGS. 11A and 11B, at least one boss 95 for supporting the main substrate 10 may be formed in the rear case frame 9. In a further example, the at least one boss 95 may be formed to protrude at predetermined intervals along portions of the rear case corresponding to edges of the main substrate 10, thereby preventing the main substrate 10 from moving in x- and y-directions. In a further example, a mounting portion for the boss 95 may be formed to have a slope at an angle of θ4 with respect to a plane. In yet another example, the angle of θ4 may be 1 or more degrees.
In another example, a screw engagement hole 96 may be formed in a side of the boss 95. In FIG. 11B, a sleeve 961 for mounting of a circular jig for screw engagement which has a predetermined width may be formed inside the screw engagement hole 96 in a circumference direction.
In a further example, the mounting portion for the boss 95 for supporting the substrate 10 is formed to have a slope in the curved electronic device 1, thereby enlarging the area of the sleeve 961 for mounting of the jig for screw engagement even without movement of the boss into the inside of the electronic device, and allowing for efficient and precise screw engagement.
Advantageously, the curved electronic device disclosed herein allow electronic components to be efficiently mounted, thereby contributing to a slim profile of the electronic device and making the appearance of the electronic device more aesthetically pleasing. In addition, excellent portability and grip feel may be provided.
Although the disclosure herein has been described with reference to particular examples, it is to be understood that these examples are merely illustrative of the principles of the disclosure. It is therefore to be understood that numerous modifications may be made to the examples and that other arrangements may be devised without departing from the spirit and scope of the disclosure as defined by the appended claims. Furthermore, while particular processes are shown in a specific order in the appended drawings, such processes are not limited to any particular order unless such order is expressly set forth herein; rather, processes may be performed in a different order or concurrently and steps may be added or omitted.
