Embodiment Construction

[0064] figure 1It is a circuit diagram of a chamfering module according to an embodiment of the present invention. The chamfering module 100 can be used to generate chamfering signals. The chamfering module 100 includes: a selection unit 110 and a control unit 120 . The selection unit 110 includes a scanning signal input terminal 111 , a first inverter N1 , a second inverter N2 , a resistor R1 , a capacitor C1 , a comparator OP1 and an AND gate A1 . The scanning signal input terminal 111 is used for periodically receiving a first potential and a second potential. When the scan signal input terminal 111 receives a first potential, the selection unit 110 generates a first control signal according to the first potential. When the first potential received by the scanning signal input terminal 111 drops to the second potential, the selection unit 110 turns off the first control signal and generates a second control signal. After the first output terminal 121 outputs the chamfer...

Abstract

The invention relates to a scanning circuit for generating cutting angle signal, a liquid crystal panel and a cutting angle signal generation method. The scanning circuit comprises a scanning module and a plurality of cutting angle modules, wherein the scanning module is provided with a plurality of scanning output ends and is used for sequentially outputting a scanning driving signal, and the scanning driving signal comprises a first level and a second level; and each cutting angle module is sequentially and electrically connected with each scanning output end, a second output end of each cutting angle module is electrically connected with a first output end of the next cutting angle module to transmit partial electric energy received by the second output end of the control unit of the first cutting angle module to the first output end of the control unit of the next cutting angle module.

Description

technical field [0001] The invention relates to a scanning circuit, a liquid crystal panel and a method for generating a clipping signal, in particular to a scanning circuit, a liquid crystal panel, and a method for generating a clipping signal by means of voltage division. Background technique [0002] Generally, the liquid crystal panel will transmit the activation signal to each gate circuit of the liquid crystal panel one by one to open the semiconductor channel layer of the TFT component that controls the charging timing of the liquid crystal unit connected to the gate circuit, so that the pixel data signal can be transmitted from the source (source) is transferred to the drain through the opened semiconductor layer, and then the liquid crystal unit (Liquid Crystal Unit) is charged. When the liquid crystal cells arranged in each arrangement are charged, the starting signal will be affected by the electrical impedance due to the increasing number of passing liquid crysta...
