Problems solved by technology

[0003] However, as the liquid crystal display tends to be larger, the number of gate drivers and the length of the wiring also increase accordingly, and the voltage loss of each driver connected in series in the prior art is constantly accumulating, so the terminal at the end The driver can no longer accurately accept the control signal sent from the external circuit, resulting in serious distortion of the display screen

Embodiment Construction

[0019] The present invention changes the traditional serial gate driver connection mode into a parallel connection mode, thereby effectively suppressing the loss of the control signal in the wiring and the driver, so that each driver can receive a consistent voltage control signal, avoiding the Poor display due to voltage loss.

[0020] Please refer to figure 2 . figure 2 is a schematic diagram of a liquid crystal display device of the present invention, wherein the liquid crystal display device 200 includes a liquid crystal display panel 210, a plurality of gate drivers 231-233 on one side thereof, and a plurality of wires of the same number as the plurality of gate drivers 221-223. One section of the multiple traces 221-223 is correspondingly connected to each gate driver, for example, the trace 221 is connected to the gate driver 231, and the other end is uniformly connected to an external printed circuit through one of the multiple connection circuits 202 On the board...

Abstract

The invention relates to a liquid crystal display device, which comprises a liquid crystal panel, wherein the liquid crystal panel is provided with a plurality of grid drivers, a plurality of running cables is connected with one grid driver, and each running cable has identical resistance value. Through the above liquid crystal display device, the traditional serial-connection grid driver connection mode is changed to the parallel-connection mode, so the loss of the control signal in the running cable and the driver can be effectively controlled, each driver can receive the consistent voltage control signal, and the unfavorable display caused by the loss of the voltage can be avoided.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular, the present invention relates to a liquid crystal display device having the same gate input signal. Background technique [0002] Liquid crystal displays have been widely used in electronic devices such as televisions, notebook computers, mobile phones, and personal digital assistants due to their low radiation, thin thickness, and low power consumption. Generally, a liquid crystal display device is mainly composed of a liquid crystal panel as a display unit, a display control unit, and a plurality of driving circuits. figure 1 It is a conventional liquid crystal display device. Such as figure 1 As shown, the liquid crystal display device 100 includes a liquid crystal panel 110, and there are a plurality of gate drivers 131-133 on one side thereof. To the printed circuit board 101 , the printed circuit board 101 can provide a control signal to the plurality of gate driv...
