Problems solved by technology
Although in an ideal design, the pixel unit will maintain the pixel voltage value during the vertical blank interval, but the pixel voltage value will still be shifted by the coupling effect of the data line signal, resulting in flicker
On the other hand, in order to avoid the polarization of the liquid crystal, the polarity of the operating voltage of the liquid crystal is reversed in operation, which makes the flickering phenomenon of the display worse.
In addition, with the evolution of display specifications, the coupling effect between pixel voltage and data lines cannot be ignored, and has become an important issue in display design.

A display panel control method and its drive circuit, the display panel control method is suitable for display panels. The display panel has at least one common electrode line and a plurality of data lines. A timing control signal is provided, which includes an active interval and a vertical blank interval, and is used to control the display panel to enter the active interval or the vertical blank interval to execute a corresponding operation process. When the display panel is in the active interval, corresponding data voltages are respectively output to each of the data lines according to the frame data. When the display panel is in the vertical blank interval, blank data voltages are respectively output to each of the data lines. Each blank data voltage is determined according to the polarity of the data voltage of the corresponding data line and the common voltage on the common electrode line. The invention also provides a driving circuit of the display panel control method.
Description
technical field [0001] The invention relates to a display panel control method and its driving circuit, in particular to a display panel control method and its driving circuit in which a display frame has a vertical blank interval. Background technique [0002] Although the display quality is not perfect, liquid crystal displays (LCDs) have been popularized in today's consumer market due to various convenient features. Briefly speaking, the liquid crystal display selectively charges and discharges each pixel unit in the pixel array through gate lines and data lines to display desired display images. Wherein, the display screen will be updated at a fixed or variable frequency. Correspondingly, the data line transmits a data signal to be written into the pixel unit, and the data signal is defined as a plurality of frames, and each frame includes the image data of a display frame. As the picture data in different frames are written into each pixel unit, the pixel array can up...
