[0023] The PCB structure of a large-size LCD screen mainly consists of a timing control board and an LCD panel source driver board. Specifically, the screen is connected to three LCD panel source driver boards: XR, XM, and XL segments. An additional timing control board connects to these three LCD panel source driver boards to power the display. This method results in an excessive number of PCB boards, leading to high design and material costs.

[0024] To address the aforementioned issues, this application provides an LCD TV that reduces the number of PCB boards used, thereby lowering costs.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

The first driver board 210, the integrated driver board 220, and the second driver board 230 are respectively electrically connected to the screen 100. The integrated driver board 220 has a timing function routing area 221 and a signal conversion function routing area 222, and a gap is provided between the timing function routing area 221 and the signal conversion function routing area 222.

[0027] It should be noted that the first driver board 210 and the second driver board 230 are LCD panel source driver boards, and the integrated driver board 220 is a PCB board that integrates the timing control board and the LCD panel source driver board. The timing function routing area 221 on the integrated driver board 220 is used to realize signal timing management and coordination, and the signal conversion function routing area 222 is used to realize the conversion of data signals into voltage output, thereby driving the screen 100. In this way, the traditional timing control board and LCD panel source driver board are integrated on a single PCB board to form the integrated driver board 220. This significantly reduces the overall PCB board area and greatly reduces production costs.

[0030] See Figure 1In one embodiment, the transmission component 200 further includes a first FPC board 300 and a first gold finger 310. The first gold finger 310 is disposed on the first driver board 210. One end of the first FPC board 300 is electrically connected to the screen 100, and the other end of the first FPC board 300 is electrically connected to the first gold finger 310. Specifically, the transmission component 200 further includes a second FPC board 320 and a second gold finger 330. The second gold finger 330 is disposed on the integrated driver board 220. One end of the second FPC board 320 is electrically connected to the screen 100, and the other end of the second FPC board 320 is electrically connected to the second gold finger 330. Specifically, the transmission component 200 further includes a third FPC board 340 and a third gold finger 350. The third gold finger 350 is disposed on the second driver board 230. One end of the third FPC board 340 is electrically connected to the screen 100, and the other end of the third FPC board 340 is electrically connected to the third gold finger 350. Specifically, the number of the first FPC board 300 is the same as the number of the first gold fingers 310, the number of the second FPC board 320 is the same as the number of the second gold fingers 330, and the number of the third FPC board 340 is the same as the number of the third gold fingers 350.
