Provided is a display apparatus. The display apparatus includes: a display panel; a chassis supporting the display panel; a printed circuit board on which an electronic component is mounted; and a supporter inserted in the printed circuit board, wherein the printed circuit board includes a first surface facing the chassis, a second surface facing a direction opposite to the first surface, and a through hole penetrating the first surface and the second surface. The supporter includes: a head fixed on the second surface of the printed circuit board; a first body positioned inside the through hole, and extending from the head toward the chassis; and a second body extending from the first body, and protruding from the through hole toward the chassis.

BACKGROUND

The disclosure relates to a display apparatus and a manufacturing method thereof, and for example, to a display apparatus having a supporter and a manufacturing method thereof.

2. Description of Related Art

A printed circuit board (PCB) is formed by printing a circuit line pattern with a conductive material such as copper on an electrically insulating board, and may refer, for example, to a board on which electronic components can be mounted. The printed circuit board is widely used in an electronic device, such as a display, a laptop computer, a mobile phone, etc.

Recently, electronic devices are more and more miniaturized and slimmed. Accordingly, electronic components, etc. mounted on a printed circuit board are nearly in contact with a housing (for example, a chassis, a cover, etc.). In this case, the electronic components are easily damaged by external vibrations, impacts, etc., and the insulating sheet may be scratched by leads of the electronic components. Furthermore, when the printed circuit board is pressed by the housing, a problem that electrical shorts are generated or the printed circuit board is bent may be generated.

To address such a problem, a PCB supporter for supporting the printed circuit board is installed in the printed circuit board. However, a manual insert supporter requires a worker's task of inserting it into a printed circuit board and then performing bonding for fixing it, which deteriorates productivity. Also, a surface mounted device (SMD) supporter raises manufacturing cost because it is a high-priced product.

The insulating sheet17may be stacked on one side of the bottom chassis15. The insulating sheet17may prevent and/or reduce electricity generated in a printed circuit board (PCB)20which will be described in greater detail below from being transmitted through the main body1a.

Hereinafter, an example in which the printed circuit board assembly10is positioned between the bottom chassis15and the rear cover16will be described. However, this is merely an example of the disclosure, and a location of the printed circuit board assembly10is not limited to this.

Referring toFIG.2, the printed circuit board assembly10may include the printed circuit board20. The printed circuit board20may include metal wires thereinside, and various electronic components30, etc. may be mounted on the printed circuit board20according to their purposes. For example, by mounting circuit devices on the printed circuit board20, the printed circuit board20may configure a circuit. For example, and without limitation, the printed circuit board20may be provided by forming wirings with a copper foil on a base which is a thin substrate made of an insulator such as an epoxy resin or a bakelite resin and then printing a lead resist thereon.

The printed circuit board20may include a first surface21and a second surface22that is opposite to the first surface21. For example, inFIG.2, the first surface21may be a bottom surface of the printed circuit board20, and the second surface22may be a top surface of the printed circuit board20. The second surface22may be a mounting surface on which the electronic components30, etc. are mounted. The first surface21may be a reverse surface which is opposite to the mounting surface. The first surface21may face the bottom chassis15. The second surface22may face the rear cover16. However, positions of the first surface21and the second surface22are an example ofFIG.2, and the positions of the first surface21and the second surface22are not limited to these.

The printed circuit board20may include a through hole23. The through hole23may penetrate the first surface21and the second surface22. A plurality of through holes23may be provided in such a way as to be spaced from each other.

The printed circuit board20may include a plurality of circuit patterns, which are not shown in the drawings. The printed circuit board20is shown to be a single layer. However, the printed circuit board20may be provided as a multi-layer.

At least one electronic component30may be mounted on the printed circuit board20. For example, the electronic component30may include a bottom component31positioned on the first surface21of the printed circuit board20, and a top component32positioned on the second surface22of the printed circuit board20. The electronic component30may include a lead33(refer toFIGS.8,9,10,11and13). For example, the electronic component30may be inserted in the printed circuit board20by Insert Mount Technology (IMT), or mounted on the printed circuit board20by Surface Mount Technology (SMT), although not limited thereto. However, the electronic component30may be mounted on the printed circuit board20by various methods.

Referring toFIGS.2,3,4and5, the supporter100may support the printed circuit board20. The supporter100may distribute an impact, etc. applied to the printed circuit board assembly10. For example, the display apparatus1may need to pass a 62369-1 Impact test which refers to a CB/UL integrated specification. The display apparatus1may pass the 62369-1 Impact test in a case in which a thickness of the insulating sheet17is maintained at 0.4 T or more even after an impact is applied to the display apparatus1by dropping a steel ball of 500 g at 1.3 m onto the display apparatus1. However, according to the slimming trend of display apparatuses, the electronic component30may damage the insulating sheet17due to an impact, etc. from the outside. For example, a problem that the insulating sheet17is scratched or penetrated by the electronic component30may be generated. The supporter100may improve a specification-related issue as described above.

The supporter100may be installed in the printed circuit board20. For example, the supporter100may be inserted in the through hole23. For example, the supporter100may be inserted in the through hole23of the printed circuit board20from the first surface21of the printed circuit board20in, for example, an Auto Insert process.

The supporter100may include a body110and a head120.

The body110may include a first body111positioned inside the through hole23. The first body111may extend from the head120toward the bottom chassis15. The first body111may be substantially in a shape of a cylinder. The first body111may correspond to the through hole23. A width of the first body111may be smaller than that of the through hole23. A diameter D1of the first body111may be smaller than a diameter D3of the through hole23. A preset space24may be formed between an outer circumference surface of the first body111and the through hole23.

The body110may include a second body112extending from the first body111. The second body112may extend from the first body111toward the bottom chassis15. The second body112may extend from the first body111away from the first surface21of the printed circuit board20. The second body112may be located outside the through hole23. The second body112may protrude toward the bottom chassis15from the through hole23of the printed circuit board20to prevent and/or reduce the electronic component30(particularly, the lead33) mounted on the printed circuit board20from interfering with the bottom chassis15.

The second body112may be spaced from the bottom chassis15. The second body112may be spaced from the insulating sheet17provided on the bottom chassis15. For example, the second body112may communicate with the first body111. The second body112may include an opening112a. A solder S may enter an internal space160of the supporter100through the opening112a.

Upon inserting of the supporter100into the through hole23from the first surface21of the printed circuit board20, the second body112may be caught by the printed circuit board20. For example, upon inserting of the supporter100into the through hole23from the first surface21, the second body112may prevent and/or block the supporter100from escaping from the printed circuit board20through the through hole23. A width of the second body112may be greater than that of the through hole23. A diameter D2of the second body112may be greater than the diameter D3of the through hole23. The second body112may not pass through the through hole23.

Referring toFIGS.4and5, the width of the second body112may be greater than that of the first body111. The diameter D2of the second body112may be greater than the diameter D1of the first body111. Accordingly, a step may be made between the first body111and the second body112, and the second body112may be caught by the first surface21of the printed circuit board20.

Referring toFIGS.4,5,6and7, the second body112may include a projection130. The projection130may be caught by the first surface21upon inserting of the supporter100into the through hole23from the first surface21. A width of the projection130may be greater than that of the first body111. A diameter of the projection130may be greater than that of the first body111. A width of the projection130may be greater than that of the through hole23. The diameter of the projection130may be greater than that of the through hole23. Accordingly, the projection130may not pass through the through hole23.

In supporters100b,100c, and100dshown inFIGS.4and5, the projection130may be substantially in a shape of a step. As shown inFIGS.6and7, the projection130may protrude in an outer radial direction of the second body112, and extend along a circumference of the second body112. However, the shape of the projection130is not limited to this, and the projection130may have any shape that is capable of being caught by the first surface21of the printed circuit board20.

A height of the supporter100may be adjusted according to a length L1of the second body112. A separation distance g1between the supporter100and the insulating sheet17may be adjusted according to the length L1of the second body112. Accordingly, the height of the supporter100may be easily managed by adjusting the length L1of the second body112. For example, a worker may design the length L1of the second body112by considering a length L2of the bottom component21, a position of the bottom chassis15, etc. In other words, a worker may easily design the height of the supporter100.

In the supporters100a,100c, and100dshown inFIGS.4and5, the second body112of the supporter100may be bent. For example, the second body112may include a bent portion140being adjacent to the bottom chassis15. For example, the bent portion140may be bent inward (see the supporter100d) or outward (see the supporter100c) from an end of the second body112.

The bent portion140may prevent and/or reduce the printed circuit board assembly10from damaging the insulating sheet17upon generation of vibrations, shaking, etc. of the printed circuit board assembly10due to an impact. For example, the bent portion140may include a curved shape, and may be prevented from or may avoid scratching or penetrating the insulating sheet17despite friction with the insulating sheet17.

Referring to the supporter100ashown inFIGS.2,4, and5, the second body112of the supporter100may further include an extension portion150extending from the bent portion140toward the first surface21of the printed circuit board20. The extension portion150may support the first surface21of the printed circuit board20. The extension portion150may be caught by the first surface21upon inserting of the supporter100into the through hole23from the first surface21of the printed circuit board20. For example, the extension portion150may prevent and/or block the supporter100from escaping from the printed circuit board20through the through hole23upon inserting of the supporter100into the through hole23from the first surface21. For example, the extension portion150may function as the projection130. In this case, a width of the extension portion150may be greater than that of the through hole23. A diameter of the extension portion150may be greater than the diameter D3of the through hole23. Accordingly, the extension portion150may not pass through the through hole23.

The supporter100may include a head120that is fixed on the second surface22of the printed circuit board20. The head120may be fixed on the mounting surface22. The head120may be fixed on the top surface22as shown inFIG.2.

The head120may be a portion extending from the first body111and protruding from the through hole23with respect to the second surface22. The head120may be clinched and fixed on the second surface22. For example, the head120may include a plurality of incision pieces120a(refer toFIG.3) formed by being incised in all directions. The plurality of incision pieces120amay be bent in an outer radial direction and bonded on the second surface22. The head120may also be referred to as a clinch head120.

The head120may be clinched in an Auto Insert process. For example, upon automatically inserting of the supporter100into the through hole23toward the second surface22from the first surface21of the printed circuit board20, the second body112having the greater width than that of the through hole23may be caught by the first surface21. In this case, a portion protruding from the second surface22through the through hole23of the supporter100may include a plurality of incision pieces120aformed by being incised in all directions. The plurality of incision pieces120amay be bent in an outer radial direction and fixed on the second surface22.

Referring toFIG.2, the length L1of the second body112of the supporter100may be longer than the length L2of the bottom component31. That is, the second body112of the supporter100may protrude in a down direction (+X direction) more than the bottom component31with respect to the first surface21. Accordingly, the supporter100may prevent and/or avoid the bottom component31from damaging other components or being damaged by the other components. The supporter100may optimize the length L2of the bottom component31. For example, the length L2of the bottom component31may be adjusted within the length L1of the second body112.

Referring toFIG.2, a separation distance g1between the second body112and the insulating sheet17may be shorter than a separation distance g2between the bottom component31and the insulating sheet17.

The supporter100may include an eyelet. For example, the supporter100may be manufactured with an existing eyelet component. Because an eyelet component is assembled in an Auto Insert process, the supporter100may also be installed in the printed circuit board20in the Auto Insert process. Accordingly, a worker's task of inserting a supporter into a printed circuit board and then bonding the supporter may be omitted unlike a manual insert supporter. Using an existing eyelet component, unlike a SMD supporter, cost may be effectively reduced. As a result, productivity of the display apparatus1may be improved.

Referring toFIG.4, the supporter100may support the printed circuit board20without separate soldering because the head120is clinched on the second surface22. For example, the supporter100may relieve an impact, etc. applied onto the printed circuit board20without separate soldering.

As shown inFIGS.5and7, to reinforce fixation power, separate soldering may be performed after the supporter100is fixed in the through hole23. For example, the second body112may be soldered on the first surface21, and the head120may be soldered on the second surface22. The solder S may be soldered to fill the inner space160of the supporter100. The solder S may be soldered to fill the space24(refer toFIG.2) between the outer circumference surface of the first body111and the through hole23. However, the solder S shown in the drawings is an example, and a shape and location of the solder S are not limited to these.

FIG.8is a partial perspective view illustrating a printed circuit board assembly to which supporters for performing an eyelet function are applied according to various embodiments.FIG.9is a partial perspective sectional view illustrating the printed circuit board assembly shown inFIG.8after a portion of the printed circuit board assembly is cut according to various embodiments.FIG.10is a cross-sectional view of the printed circuit board assembly shown inFIG.8according to various embodiments.FIG.11is a cross-sectional view illustrating supporters for performing an eyelet function according to various embodiments.FIG.12is a cross-sectional view illustrating a supporter including a solder reinforcement hole according to various embodiments.FIG.13is a cross-sectional view illustrating a printed circuit board assembly to which the supporter shown inFIG.12is applied according to various embodiments. Content overlapping with that described above may not be repeated here.

Referring toFIG.8, the supporter100may perform an eyelet function in addition to a function of a PCB supporter supporting the printed circuit board20. For example, the supporter100may fix the lead33of the electronic component30. The supporter100may be applied to a portion in which overweight, a high voltage, or an overcurrent is generated, thereby improving PL-type defects (for example, heating, an electrical shock, etc.).

The lead33may be located inside the supporter100. For example, the lead33may be positioned in the internal space of the supporter100. The lead33may be fixed in the supporter100by soldering. A solder S may be filled in the internal space160of the supporter100in a state in which the lead33is positioned inside the supporter100. A molten solder S may be filled in the internal space160and then hardened, and accordingly, the lead33may be stably bonded with the supporter100. For example, the solder S may enter the internal space160through the opening120aof the second body120.

For example, the second body112may be soldered on the first surface21, the head120may be soldered on the second surface22, and the space24between the outer circumference surface of the body111and the through hole23may be soldered.

The length L1of the second body112of the supporter100may be longer than a length L3of the lead33. For example, the length L1of the second body112of the supporter100may protrude in a down direction (+X direction) more than the lead33with respect to the first surface21. Accordingly, the supporter100may prevent and/or reduce the lead33from damaging other components or being damaged by the other components. For example, a problem in which the lead33presses the insulating sheet17by an impact, vibrations, etc. applied from the outside to scratch or penetrate the insulating sheet17may be prevented or avoided. A problem in which the lead33is damaged by a friction with other components to cause connecting errors may be prevented or avoided.

The supporter100may optimize the length L3of the lead33. For example, the length L3of the lead33may be adjusted within the length L2of the second body121, and accordingly, the length L3of the lead33may be easily managed.

As shown inFIGS.12and13, the supporter100may include a solder reinforcement hole170. A plurality of solder reinforcement holes170may be arranged along a circumferential direction of the supporter100. The solder reinforcement hole170may enable the solder S to more smoothly enter the internal space160of the supporter100.

A worker may check a soldering task with his/her naked eyes through the solder reinforcement hole170. While the solder S is filled in the internal space16of the supporter100, the worker may determine a degree of soldering with his/her naked eyes through the solder reinforcement hole170. That is, the worker may check the solder S being filled from the opening112aof the second body112up to the head120. Accordingly, a problem in which a subsequent process is performed after inadequate soldering may be avoided. Also, by adjusting a size of the solder reinforcement hole170, a speed of soldering may be adjusted. As a result, because the supporter100includes the solder reinforcement hole170, solderability may be improved.

FIG.14is a cross-sectional view illustrating a printed circuit board assembly to which a supporter used as a via component is applied according to various embodiments. Content overlapping with that described above may not be repeated here.

Referring toFIG.14, the supporter100may be used as a via component. The head120may be soldered on the second surface22, and the second body112may be soldered on the first surface21. For example, the supporter100may be bonded with the surfaces21and22of the printed circuit board20through, for example, a cream solder. A via hole180may be formed inside the supporter100. For example, the internal space160of the supporter100may be formed as the via hole180. The electronic component30, etc. may be not inserted in the via hole180. The via hole180may enable connections between multiple layers of the printed circuit board20. The via hole180may reinforce a ground GND, and remove noise.

The supporter100according to various embodiments of the disclosure may perform complex functions. The supporter100may perform various functions according to a position of the supporter100, coupling between the electronic components30, etc. The supporter100may perform a PCB supporter function for distributing an impact applied on the printed circuit board20. The supporter100may perform an eyelet function for fixing the lead33. For example, the supporter100may be applied to a portion in which overweight, a high voltage, or an overcurrent is generated, thereby improving PL-type defects. The supporter100may perform a via component function. For example, the supporter100may form the via hole180therein to connect the first surface21of the printed circuit board20with the second surface22of the printed circuit board20, or allow connections between multiple layers.

A method for manufacturing the display apparatus1will be described in greater detail below. For example, a process in which the supporter100is inserted and fixed in the printed circuit board20during an auto insert process will be described.

The printed circuit board20may be prepared. The printed circuit board20may include the mounting surface22on which the electronic component30is mounted, the reverse surface21that is opposite to the mounting surface22, and the through hole23penetrating the mounting surface22and the reverse surface21.

The supporter100may be inserted in the through hole23from the reverse surface21of the printed circuit board20. Upon inserting of the supporter100into the through hole23from the reverse surface21, the second body112of the supporter100may be caught by the reverse surface21. Accordingly, the second body112may not penetrate the through hole23and may protrude with respect to the reverse surface21. A portion protruding from the mounting surface22of the supporter100may be clinched and fixed on the mounting surface22. Thereby, the clinch head120may be formed. The above-described process may be successively performed in the auto insert process, and accordingly, productivity may be raised.

The printed circuit board20(e.g., the printed circuit board assembly10) in which the supporter100is inserted may be installed in the bottom chassis15. For example, the second body112of the supporter100may be located between the reverse surface21of the printed circuit board20and the bottom chassis15.
