Problems solved by technology

[0004] At present, the mainstream design of LCD panels is developing towards narrow bezels, and they are trying to reduce the design of the glass edge in various ways as much as possible. Every small space saving may be crucial, so too many wires will occupy the The space at the edge of the glass, it is necessary to reduce the number of traces

Embodiment Construction

[0026] A scanning driving circuit of a liquid crystal panel, the driving circuit of the liquid crystal panel includes a delay component, the input end of the delay component is coupled to an enabling control signal, and the output terminal is coupled to a clock pulse signal, and the delay component is The delay time is less than the action time of a single enable control signal.

[0027] Due to the adoption of the delay component in the present invention, the delay component can output the same input signal after a delay, and the pulse width driven by each scanning line is related to the signal width of one cycle of the clock pulse signal, and is related to the signal width within one cycle of the clock pulse signal. The pulse width of the high-level signal is not directly related. Therefore, the pulse width of the clock pulse signal is consistent with the pulse width of the enable control signal, so that signal multiplexing can be realized through the delay component, and the ...

Abstract

A scanning drive circuit of a liquid crystal panel, a liquid crystal display device and a driving method are disclosed. The drive circuit of the liquid crystal panel comprises a time delay component, wherein the input end of the time delay component is coupled to an enable control signal (OE) while the output end of the time delay component is coupled to a clock pulse signal (CLK), and the delayed time of the time delay component is less than the action time of single enable control signal (OE).

Description

technical field [0001] The invention relates to the field of liquid crystal display, and more specifically, relates to a scanning driving circuit of a liquid crystal panel, a liquid crystal display device and a driving method. Background technique [0002] The liquid crystal display panel includes criss-cross scanning lines and control lines, and the scanning lines are controlled by scanning driving chips arranged on both sides of the liquid crystal panel. At present, there are 3 control signals required by the scanning driver chip that controls the opening and closing of each line of the liquid crystal display, namely the start pulse signal STV (startvoltage pulse), which controls the beginning of the first line; the clock pulse signal CKV (clockvoltagepulse), which is provided to the scan driver The chip shift register controls the switching frequency of each row, and starts to act when the rising edge detects that STV is high; the output enable control signal OE (output e...
