Description
本發明是有關一種電路板固定結構及一種具有電路板固定結構的顯示裝置。 The present invention relates to a circuit board fixing structure and a display device having the circuit board fixing structure.
習知的液晶顯示裝置包含背光模組與位於背光模組上的液晶顯示面板。軟性電路板(FPC)將液晶顯示面板與來源電路板(Source PCB；SPCB)電性連接。為了防止電磁干擾(EMI)與靜電放電(ESD)的問題產生，設計者通常將來源電路板與背光模組的背板電性連接，使SPCB接地而避免電磁干擾與靜電放電的問題產生。在習知技術中，SPCB安裝於背光模組的側邊，並將導電布設置於SPCB與背板之間以電性連接SPCB與背板，使SPCB接地。 A conventional liquid crystal display device includes a backlight module and a liquid crystal display panel on the backlight module. The flexible circuit board (FPC) electrically connects the liquid crystal display panel to the source circuit board (Source PCB; SPCB). In order to prevent electromagnetic interference (EMI) and electrostatic discharge (ESD) problems, designers usually electrically connect the source board to the back panel of the backlight module to ground the SPCB to avoid electromagnetic interference and electrostatic discharge. In the prior art, the SPCB is mounted on the side of the backlight module, and the conductive cloth is disposed between the SPCB and the back board to electrically connect the SPCB and the back board to ground the SPCB.
固定SPCB的方式例如使用額外的支撐件設於SPCB背對導電布的位置，並以背光模組前框壓迫支撐件，使SPCB壓迫導電布而電性連接背板。然而，此方式需使用導電布並設置複數個支撐件，使背光模組的成本增加。當前框壓迫支撐件時，支撐件可能會掉落，尚失壓迫SPCB的功能。在維 修或重工後，導電布及支撐件可能無法重複使用，使背光模組的良率難以提升。 The method of fixing the SPCB is, for example, using an additional support member disposed at a position opposite to the conductive cloth of the SPCB, and pressing the support member with the front frame of the backlight module, so that the SPCB presses the conductive cloth and electrically connects the back plate. However, this method requires the use of a conductive cloth and a plurality of support members to increase the cost of the backlight module. When the current frame presses the support member, the support member may fall, and the function of the SPCB is still lost. In dimension After repairing or heavy work, the conductive cloth and the support member may not be reused, which makes the yield of the backlight module difficult to increase.
又例如，可將SPCB固定在背光模組框體的卡勾 上，並使用導電布將SPCB與背板接地。然而，此方式也同樣需使用導電布，使背光模組的成本增加。在維修或重工後，導電布可能無法重複使用，使背光模組的良率難以提升。此外，部分卡勾位於SPCB上方抵靠SPCB頂面，另一部分卡勾位於SPCB下方抵靠SPCB底面，因此不易安裝，會增加組裝SPCB的時間。 For another example, the SPCB can be fixed on the hook of the backlight module frame. Ground the SPCB and the backplane with a conductive cloth. However, this method also requires the use of a conductive cloth to increase the cost of the backlight module. After repair or rework, the conductive cloth may not be reused, making it difficult to increase the yield of the backlight module. In addition, some of the hooks are located above the SPCB on the top surface of the SPCB, and the other part of the hooks are located below the SPCB against the bottom surface of the SPCB, so it is not easy to install and will increase the time for assembling the SPCB.

The hook portion has a free end that is away from the support portion. The orthographic projection of the hook portion on the side wall at least partially overlaps the orthographic projection of the hollowed out region on the side wall. The circuit board is positioned between the limiting bump, the support portion and the hook portion, and a vertical distance between the floating end and the support portion is greater than or equal to a width of the circuit board.
本發明之另一技術態樣為一種顯示裝置。 Another aspect of the present invention is a display device.
根據本發明一實施方式，一種顯示裝置包含顯示 面板、電路板固定結構與軟性電路板。電路板固定結構包含第一框架、第二框架、夾持結構與電路板。第一框架具有限位凸塊。限位凸塊位於第一框架之側壁。第二框架位於第一框架上且承載顯示面板。夾持結構沿側壁表面由第二框架凸出。夾持結構包含本體部、支撐部與卡勾部。本體部連接第二框架。本體部具有鏤空區。限位凸塊凸出於鏤空區。支撐部位於本體部遠離第二框架之一端。卡勾部連接於支撐部。卡勾部具有遠離支撐部之懸空端。卡勾部於側壁的正投影與鏤空區於側壁的正投影至少部分重疊。電路板定位於限位凸塊、支撐部與卡勾部之間，且懸空端與支撐部之間的垂直距離大於或等於電路板的寬度。軟性電路板電性連接顯示面板與電路板。 According to an embodiment of the invention, a display device includes a display Panel, circuit board fixed structure and flexible circuit board. The circuit board fixing structure includes a first frame, a second frame, a clamping structure and a circuit board. The first frame has a limit bump. The limit bumps are located on the side walls of the first frame. The second frame is located on the first frame and carries the display panel. The clamping structure projects from the second frame along the sidewall surface. The clamping structure comprises a body portion, a support portion and a hook portion. The body portion is coupled to the second frame. The body portion has a hollowed out area. The limit bumps protrude from the cutout. The support portion is located at one end of the body portion away from the second frame. The hook portion is connected to the support portion. The hook portion has a free end that is away from the support portion. The orthographic projection of the hook portion on the side wall at least partially overlaps the orthographic projection of the hollowed out region on the side wall. The circuit board is positioned between the limiting bump, the support portion and the hook portion, and a vertical distance between the floating end and the support portion is greater than or equal to a width of the circuit board. The flexible circuit board is electrically connected to the display panel and the circuit board.
在本發明上述實施方式中，第一框架具有限位凸 塊，且夾持結構的本體部具有鏤空區，使得限位凸塊可凸出於鏤空區。由於卡勾部於第一框架之側壁的正投影與鏤空區於第一框架之側壁的正投影至少部分重疊，因此當電路板從卡勾部的懸空端與本體部之間的間隙***至支撐部時，第一框架的限位凸塊可抵接電路板，使電路板定位於限位凸塊、支撐部與卡勾部之間。此外，卡勾部的懸空端與支撐部之間的垂直距離大於或等於電路板的寬度，更可加強對電路板的固定性。 In the above embodiment of the present invention, the first frame has a limit convex And the body portion of the clamping structure has a hollowed out area, such that the limiting protrusion can protrude from the hollowed out area. Since the orthographic projection of the hook portion on the side wall of the first frame at least partially overlaps with the orthographic projection of the hollow region on the side wall of the first frame, when the circuit board is inserted into the support from the gap between the suspended end of the hook portion and the body portion When the portion is bounded, the limiting protrusion of the first frame can abut the circuit board, so that the circuit board is positioned between the limiting protrusion, the supporting portion and the hook portion. In addition, the vertical distance between the suspended end of the hook portion and the support portion is greater than or equal to the width of the circuit board, and the fixing property to the circuit board is further enhanced.
本發明的電路板固定結構可藉由限位凸塊與卡勾 部定位電路板，使電路板與限位凸塊抵接而達到接地的效果，不需使用額外的支撐件壓迫電路板，也不需使用額外的導電布對電路板接地。 The circuit board fixing structure of the invention can be supported by a limit bump and a hook The positioning circuit board allows the circuit board to abut against the limit bumps to achieve the grounding effect, without using an additional support member to press the circuit board, and does not need to use an additional conductive cloth to ground the circuit board.

第1A圖繪示根據本發明一實施方式之顯示裝置200的立體圖。第1B圖繪示第1A圖之顯示裝置沿線段1B-1B 的剖面圖。同時參閱第1A圖與第1B圖，顯示裝置200包含顯示面板210、電路板固定結構100與軟性電路板220。其中，顯示面板210可以為液晶面板，但不以此為限。電路板固定結構100包含第一框架110、第二框架120、夾持結構130與電路板140。第一框架110承載背光模組240。第二框架120位於第一框架110上並承載顯示面板210，且第二框架120圍繞第一框架110的邊緣。 FIG. 1A is a perspective view of a display device 200 according to an embodiment of the present invention. FIG. 1B is a diagram showing the display device of FIG. 1A along line segment 1B-1B Sectional view. Referring to FIGS. 1A and 1B, the display device 200 includes a display panel 210, a circuit board fixing structure 100, and a flexible circuit board 220. The display panel 210 can be a liquid crystal panel, but is not limited thereto. The circuit board fixing structure 100 includes a first frame 110, a second frame 120, a clamping structure 130, and a circuit board 140. The first frame 110 carries a backlight module 240. The second frame 120 is located on the first frame 110 and carries the display panel 210, and the second frame 120 surrounds the edge of the first frame 110.
第2圖繪示第1A圖之電路板固定結構100的局部放大圖。於此實施例中，夾持結構130沿第一框架110之側壁111表面設置且由第二框架120凸出。夾持結構130包含本體部132、支撐部134與卡勾部136。夾持結構130的本體部132連接第二框架120。支撐部134位於本體部132遠離第二框架120之一端。卡勾部136連接於支撐部134。卡勾部136具有遠離支撐部134之懸空端135，且懸空端135與支撐部134之間的垂直距離H大於或等於電路板140的寬度W，使得電路板140可在垂直方向固定於卡勾部136之內。 FIG. 2 is a partial enlarged view of the circuit board fixing structure 100 of FIG. 1A. In this embodiment, the clamping structure 130 is disposed along the surface of the sidewall 111 of the first frame 110 and protrudes from the second frame 120. The clamping structure 130 includes a body portion 132, a support portion 134 and a hook portion 136. The body portion 132 of the clamping structure 130 is coupled to the second frame 120. The support portion 134 is located at one end of the body portion 132 away from the second frame 120. The hook portion 136 is coupled to the support portion 134. The hook portion 136 has a floating end 135 away from the support portion 134, and the vertical distance H between the floating end 135 and the support portion 134 is greater than or equal to the width W of the circuit board 140, so that the circuit board 140 can be fixed to the hook in the vertical direction. Within section 136.
此外，軟性電路板220電性連接顯示面板210與電路板140，用以傳輸訊號。 In addition, the flexible circuit board 220 is electrically connected to the display panel 210 and the circuit board 140 for transmitting signals.
第3圖繪示第2圖之電路板固定結構100省略電路板140時的立體圖。同時參閱第2圖與第3圖，電路板固定結構100的第一框架110具有限位凸塊112。限位凸塊112位於第一框架110之側壁111。在製作第一框架110時，限位凸塊112與側壁111可以為一體成型，但不在此限。夾持結構130的本體部132具有鏤空區133，鏤空區133的位置對應限位凸塊112的 位置，使得限位凸塊112可凸出於鏤空區133。 FIG. 3 is a perspective view showing the circuit board fixing structure 100 of FIG. 2 omitting the circuit board 140. Referring to FIGS. 2 and 3 simultaneously, the first frame 110 of the circuit board fixing structure 100 has a limiting bump 112. The limiting bump 112 is located on the sidewall 111 of the first frame 110. When the first frame 110 is fabricated, the limiting protrusion 112 and the side wall 111 may be integrally formed, but not limited thereto. The body portion 132 of the clamping structure 130 has a hollowed out area 133, and the position of the hollowed out area 133 corresponds to the limiting protrusion 112. The position is such that the limit bump 112 can protrude from the cutout 133.
此外，夾持結構130的卡勾部136於側壁111的正 投影與本體部132的鏤空區133於側壁111的正投影至少部分重疊。這樣的設計，當電路板140從卡勾部136之懸空端135與本體部132之間的間隙***到支撐部134後，電路板140可定位於限位凸塊112、支撐部134與卡勾部136之間。因此電路板140可被卡勾部139壓抵於限位凸塊112上。 In addition, the hook portion 136 of the clamping structure 130 is positive on the side wall 111 The projection and the orthographic projection of the hollowed out region 133 of the body portion 132 at least partially overlaps the sidewall 111. In such a design, after the circuit board 140 is inserted into the support portion 134 from the gap between the floating end 135 of the hook portion 136 and the body portion 132, the circuit board 140 can be positioned on the limiting protrusion 112, the support portion 134 and the hook Between the sections 136. Therefore, the circuit board 140 can be pressed against the limiting bump 112 by the hook portion 139.
在以下敘述中，將詳細說明電路板140定位時的狀態。 In the following description, the state when the circuit board 140 is positioned will be described in detail.
第4圖繪示第2圖之電路板固定結構100沿線段4-4的剖面圖。同時參閱第2圖與第4圖，第一框架110的限位凸塊112往卡勾部136的方向凸出鏤空區133。當電路板140位於限位凸塊112、支撐部134與卡勾部136之間時，限位凸塊112與卡勾部136可分別抵接電路板140的相對兩側，避免電路板140移動。此外，由於卡勾部136的懸空端135與支撐部134之間的垂直距離H大於或等於電路板140的寬度W，使得電路板140可在垂直方向固定於卡勾部136之內。 4 is a cross-sectional view of the circuit board fixing structure 100 of FIG. 2 taken along line 4-4. Referring to FIGS. 2 and 4, the limiting protrusion 112 of the first frame 110 protrudes from the cutout portion 133 in the direction of the hook portion 136. When the circuit board 140 is located between the limiting protrusion 112 and the supporting portion 134 and the hook portion 136, the limiting protrusion 112 and the hook portion 136 can respectively abut on opposite sides of the circuit board 140 to prevent the circuit board 140 from moving. . In addition, since the vertical distance H between the hanging end 135 of the hook portion 136 and the support portion 134 is greater than or equal to the width W of the circuit board 140, the circuit board 140 can be fixed in the vertical direction in the hook portion 136.
在本實施方式中，第一框架110的材質可以為金屬，且限位凸塊112可以為導電材料。限位凸塊112與第一框架110可以為一體成型的金屬件，但不在此限。當電路板140與限位凸塊112抵接時，電路板140的接地墊(未繪出)可透過限位凸塊112而與第一框架110的電性連接，達到接地的效果。 In this embodiment, the material of the first frame 110 may be metal, and the limiting bumps 112 may be conductive materials. The limiting block 112 and the first frame 110 may be integrally formed metal parts, but not limited thereto. When the circuit board 140 is in contact with the limiting bumps 112, the grounding pads (not shown) of the circuit board 140 can be electrically connected to the first frame 110 through the limiting bumps 112 to achieve the grounding effect.
因此，本發明的電路板固定結構100不僅可利用限位凸塊112與卡勾部136來定位電路板140，還藉由限位凸塊 112抵接電路板140，使電路板140接地。電路板固定結構100不需使用額外的支撐件定位電路板140，也不需使用額外的導電布對電路板140接地，且限位凸塊112與第一框架110可以為一體成型，夾持結構130與第二框架120也可以為一體成型，因此可節省材料成本與組裝時間。此外，電路板140可拆卸地定位於限位凸塊112、支撐部134與卡勾部136之間，因此容易維修或重工，可提升良率。 Therefore, the circuit board fixing structure 100 of the present invention can not only use the limiting bump 112 and the hook portion 136 to position the circuit board 140, but also by the limiting bump. 112 abuts the circuit board 140 to ground the circuit board 140. The circuit board fixing structure 100 does not need to use an additional support member to position the circuit board 140, and does not need to use an additional conductive cloth to ground the circuit board 140, and the limiting protrusion 112 and the first frame 110 can be integrally formed, and the clamping structure The 130 and the second frame 120 may also be integrally formed, thereby saving material cost and assembly time. In addition, the circuit board 140 is detachably positioned between the limiting protrusion 112, the supporting portion 134 and the hook portion 136, so that it is easy to repair or rework, and the yield can be improved.
在本實施方式中，第二框架120的材質可以為塑 膠，使卡勾部136具有彈性。限位凸塊112與卡勾部136之間的垂直距離d1小於或等於電路板140的厚度d2，以確保電路板140能與限位凸塊112、卡勾部136抵接。當電路板140的厚度d2大於垂直距離d1時，具彈性卡勾部136可將電路板140緊密壓迫於限位凸塊112，如此一來不僅可將電路板140固定的更加牢固，也能避免電路板140離開限位凸塊112而接地不良。 In this embodiment, the material of the second frame 120 may be plastic. The glue makes the hook portion 136 elastic. The vertical distance d1 between the limiting bump 112 and the hook portion 136 is less than or equal to the thickness d2 of the circuit board 140 to ensure that the circuit board 140 can abut the limiting bump 112 and the hook portion 136. When the thickness d2 of the circuit board 140 is greater than the vertical distance d1, the elastic hook portion 136 can tightly press the circuit board 140 against the limiting protrusion 112, so that not only the circuit board 140 can be fixed more firmly, but also can be avoided. The circuit board 140 leaves the limit bump 112 and is poorly grounded.
夾持結構130還可包含延伸部131。延伸部131連 接支撐部134，且延伸部131與卡勾部136分別朝相反方向延伸。延伸部131具有凹槽137。凹槽137位於延伸部131與支撐部134的連接處，且凹槽137由與卡勾部136的邊緣朝遠離卡勾部136的方向延伸。當電路板140位於限位凸塊112與卡勾部136之間時，延伸部131及其凹槽137的設計可在扳動卡勾部136時分散與支撐部134連接處的應力，防止於連接處斷裂。 The clamping structure 130 can also include an extension 131. Extension 131 The support portion 134 is connected, and the extension portion 131 and the hook portion 136 respectively extend in opposite directions. The extension 131 has a recess 137. The groove 137 is located at the junction of the extension portion 131 and the support portion 134, and the groove 137 extends from the edge of the hook portion 136 away from the hook portion 136. When the circuit board 140 is located between the limiting protrusion 112 and the hook portion 136, the extension portion 131 and the groove 137 thereof are designed to disperse the stress at the connection with the support portion 134 when the hook portion 136 is pulled, thereby preventing The joint breaks.
卡勾部136之懸空端135還可具有導引板138。導 引板138具有鄰近電路板140之第一側139a與遠離電路板140之第二側139b。第一側139a與第一框架110之間的垂直距離d3 小於第二側139b與第一框架110之間的垂直距離d4。也就是說，導引板138是傾斜的，可方便電路板140從卡勾部136的懸空端135***間隙。此外，導引板138的第一側139a朝鏤空區133的方向凸出，可避免電路板140輕易從卡勾部136的懸空端135脫離。 The free end 135 of the hook portion 136 can also have a guide plate 138. guide The lead plate 138 has a first side 139a adjacent to the circuit board 140 and a second side 139b remote from the circuit board 140. The vertical distance d3 between the first side 139a and the first frame 110 It is smaller than the vertical distance d4 between the second side 139b and the first frame 110. That is, the guide plate 138 is inclined to facilitate insertion of the circuit board 140 into the gap from the free end 135 of the hook portion 136.
