Angle cutting system of display and timing sequence angle cutting control method thereof

Abstract

The invention discloses an angle cutting system of a display and a timing sequence angle cutting control method thereof. The angle cutting system is connected to a grid circuit and comprises a timing sequence controller and an angle cutting module; according to a system input signal, the timing sequence controller can generate an enabling signal, an angle cutting triggering signal and a reference work signal of which the frequencies are the same as the frame frequency of the system input signal; the angle cutting module regulates the reference work signal by using the enabling signal and the angle cutting triggering signal, so that the reference work signal carriers a first angle cutting voltage and the first angle cutting voltage is input to the grid circuit; and when the frame frequency is changed, the triggering points and triggering time of the enabling signal and the angle cutting triggering signal are regulated by the timing sequence controller, so that the angle cutting module regulates the reference work signal to enable the reference work signal to carry a second angle cutting voltage equivalent to the first angle cutting voltage and then the second angle cutting voltage is output to the grid circuit, thus the charging time and charging charge of a liquid crystal unit connected with the gird circuit are unchanged.

Description

technical field [0001] The present invention relates to a timing controller and a timing control method of a liquid crystal panel, in particular to a reference trigger signal and a chamfering system and timing of a system signal that still provides the same signal information before and after the frame frequency change Chamfer control method. Background technique [0002] At present, the energy-saving requirement of electronic equipment has been one of the main indicators designed by manufacturers, and the same is true for active-matrix displays such as liquid crystal displays and OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) displays. Therefore, manufacturers develop and adjust the frame frequency of the working signal to reduce the power consumption of the display under different working environments. For example, during the working mode, the timing controller of the display provides a reference working signal with a frame rate of 60Hz, while during ...

Problems solved by technology

However, after the frame rate is switched, the charging time of the liquid crystal components will be inconsistent, which will cause differences in the display brightness of the liquid crystal panel, and then cause the screen to flicker momentarily.

In addition, the change of the frame rate will cause the waveform of the corner-cutting voltage generated by the corner-cutting module to be inconsistent, resulting in inconsistent charging of the charging charge, making the situation of the screen flickering worse
