Explosion map. It should be understood that FIG. 6 omits some of the components shown in FIG. 5 for convenience of explanation, and also omits the side wall of the metal frame, for example, extending from the periphery of the bottom plate and then bending inward to accommodate the light-emitting two. The groove structure of the polar body. The display device 300 includes an integrated backlight module 301, a plurality of optical films 360, a display panel 370, a plastic frame 380, and an adhesive tape 390. The optical film 360 is disposed above the integrated backlight module 301, and the display panel 370 is disposed above the optical film 360. The plastic frame 380 and the integrated backlight module 301 are engaged with each other to accommodate the optical film 360 and the display panel 370. A hard tape 390 is attached to the periphery of the upper surface of the display panel 370 and extends around the periphery of the cover frame 380 to fix the display panel 370 and the frame 380. The integrated backlight module 301 includes a digital board 310, a light emitting diode 320, a metal frame 330, a light guide plate 340 and a reflective sheet 350. The metal frame 330 includes a bottom plate 3301 and a side wall 3302. The side wall 3302 surrounds the light guide plate 340, and the side wall 3302 is connected to the periphery of the bottom plate 3301.
圖5所示的顯示裝置300與圖1所示顯示裝置100的差異為，數位板310改為配置於底板3301的下方，反射 片350配置於底板3301的上方，導光板340相對於其出光面342之另一側配置於反射片350的上方。底板3301透設有第一開口331與第二開口332，數位板310佈設有電磁感應線路311與發光二極體線路312，發光二極體320設置於數位板310的上方且電性連接於發光二極體線路312。其中，第一開口331對應電磁感應線路311而設置，第二開口332對應發光二極體320而設置。 The difference between the display device 300 shown in FIG. 5 and the display device 100 shown in FIG. 1 is that the tablet 310 is disposed under the bottom plate 3301 instead of being reflected. The sheet 350 is disposed above the bottom plate 3301, and the light guide plate 340 is disposed above the reflection sheet 350 with respect to the other side of the light exit surface 342. The bottom plate 3301 is provided with a first opening 331 and a second opening 332. The digital board 310 is provided with an electromagnetic induction line 311 and a light-emitting diode line 312. The light-emitting diode 320 is disposed above the digital board 310 and electrically connected to the light-emitting diode 310. Diode line 312. The first opening 331 is disposed corresponding to the electromagnetic induction line 311, and the second opening 332 is disposed corresponding to the LED 201.
具體而言，第一開口331位於電磁感應線路311的正上方，且於水平面上來看，第一開口331的開口面積、形狀與位置皆大體上相同於電磁感應線路311於數位板310上的佈設區域，或較佳的第一開口331的面積大於電磁感應線路311的佈設區域，因此底板3301並不會因為其本身的金屬材質而干擾電磁感應線路311的訊號感應功能。在不同實施例中，金屬框架亦可採用非金屬材質，因而即使金屬框架並未設置有所述第一開口，也不致影響訊號感應功能。另外，數位板310的一側緣往上折彎後再水平往外延伸，其所延伸的部份佈設有發光二極體線路312，其上設置有發光二極體320，因而發光二極體320可穿過第二開口332設置且毗鄰導光板340的入光面341。本實施例的優點在於，在整合式背光模組或顯示裝置完成組裝並進行檢驗時，若發現訊號感應功能或發光功能有問題，可以簡便的針對數位板與發光二極體進行抽換或檢修，如此可大幅降低製程上或維修上的複雜度。 Specifically, the first opening 331 is located directly above the electromagnetic induction line 311, and the opening area, shape and position of the first opening 331 are substantially the same as those of the electromagnetic induction line 311 on the digital board 310 as viewed in a horizontal plane. The area, or the preferred area of the first opening 331 is larger than the area of the electromagnetic induction line 311. Therefore, the bottom plate 3301 does not interfere with the signal sensing function of the electromagnetic induction line 311 due to its own metal material. In different embodiments, the metal frame can also be made of a non-metal material, so that even if the metal frame is not provided with the first opening, the signal sensing function is not affected. In addition, one side edge of the digital board 310 is bent upward and then extended horizontally. The extended portion is provided with a light-emitting diode line 312 on which the light-emitting diode 320 is disposed, and thus the light-emitting diode 320 is disposed. The light incident surface 341 of the light guide plate 340 may be disposed through the second opening 332. The advantage of this embodiment is that when the integrated backlight module or the display device is assembled and inspected, if the signal sensing function or the lighting function is found to be problematic, the tablet and the LED can be easily exchanged or repaired. This can greatly reduce the complexity of the process or maintenance.
綜上所述，本發明所提出的一種整合式背光模組與使 用其之顯示裝置，係將發光二極體線路與發光二極體整合至數位板上，相較於習知技術，本發明使得整合式背光模組與顯示裝置在組裝上，不但能減少人力與工時的耗費，並且能降低對位組裝的難度，從而提高良率，同時還能節省材料成本。另外，本發明還提出另一種整合式背光模組與使用其之顯示裝置，其藉由鍍在數位板上的反射層來取代反射片，可降低顯示裝置的整體厚度與材料支出。本發明還提出又一種整合式背光模組與使用其之顯示裝置，其係將數位板改置於底板下方，並在底板上透設有分別與電磁感應線路與發光二極體對應的第一開口與第二開口，如此不但不會影響觸控功能，還能提高檢修時的便利性。 In summary, the present invention provides an integrated backlight module and With the display device, the LED array and the LED are integrated on the digital board. Compared with the prior art, the invention enables the integrated backlight module and the display device to be assembled, thereby reducing manpower. It is costly with working hours and can reduce the difficulty of alignment assembly, thereby increasing yield while saving material costs. In addition, the present invention also provides another integrated backlight module and a display device using the same, which replaces the reflective sheet by a reflective layer plated on the digital board, thereby reducing the overall thickness and material expenditure of the display device. The invention also proposes an integrated backlight module and a display device using the same, which is to change the digital board to the bottom of the bottom plate, and the first surface corresponding to the electromagnetic induction line and the light emitting diode is respectively disposed on the bottom plate. The opening and the second opening not only do not affect the touch function, but also improve the convenience during maintenance.
