Problems solved by technology

When the data signal is switched, that is, at time t1, the scanning signal is not low level (as shown by the dotted line box in the figure), that is, the TFT on the scanning line is not completely closed, thus causing the problem of wrong charging, which affects the display effect

Abstract

A driving signal compensation method and device. The method comprises: obtaining a first phase difference between an output scanning signal and an output data signal of each pixel (S101); adjusting the phase of an input scanning signal or an input data signal of a corresponding pixel according to the first phase difference, to make the phase difference between the output scanning signal and the output data signal of the pixel after adjustment equal to the phase difference between the input scanning signal and the input data signal after adjustment (S102).

Description

【Technical field】 [0001] The invention relates to the technical field of displays, in particular to a compensation method and device for a driving signal. 【Background technique】 [0002] A liquid crystal display is currently the most widely used flat panel display, and is used in various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. The liquid crystal display commonly used at present is usually composed of upper and lower substrates and a liquid crystal layer, and the substrate is composed of glass and electrodes. When electrodes are provided on the upper and lower substrates, displays in vertical electric field modes can be formed, such as TN (Twist Nematic) mode, VA (Vertical Alignment) mode, and MVA (Multi-domain Vertical Alignment) developed to solve the problem of narrow viewing angles. When electrodes are provided on only one side of the substrate, a display in a lateral el...
