Liquid crystal display device

Abstract

A liquid crystal display device includes a display panel, and the display panel includes a plurality of scan lines, a gate drive circuit, and a clock circuit. This clock circuit includes a clock generator and an adjustment circuit. The clock generator generates a clock signal, and the clock signal has a first high potential level and a first low potential level. The adjustment circuit is connected with the clock generator to receive the clock signal, and then generates a modified clock signal with the same period as the clock signal. The modified clock signal has a second high potential level and a second low potential level. The gate driving circuit is connected with the clock circuit to receive the modified clock signal, and uses the modified clock signal as a gate driving signal to drive the plurality of scan lines.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device containing a low-temperature polysilicon thin film transistor. Background technique [0002] Liquid crystal display devices have the advantages of high image quality, small size, low driving voltage, and low power consumption, making liquid crystal display screens widely used in today's portable information products, such as mobile phones, notebook computers, personal digital assistants, etc. . However, there is often a problem with large-sized liquid crystal display devices, that is, the larger the screen size, the more serious the problem of flicker. [0003] Generally speaking, a liquid crystal display device has a liquid crystal panel, wherein a gate (gate) driving circuit outputs a gate driving signal to sequentially turn on thin film transistors (TFTs) on the scanning lines. Usually the waveform of the driving signal is a square wave, but ...

[0005] However, the above methods must provide a variable voltage source. Although the effect of modifying the waveform of the gate drive signal can be achieved, the change of the voltage source will cause more power consumption. In addition, the known methods will increase the circuit. Complexity, relatively will increase the cost of the process
