Description

Liquid crystal display capable of improving screen flicker and related driving method technical field The invention relates to a liquid crystal display and a related driving method, in particular to a liquid crystal display capable of improving screen flicker and a related driving method. Background technique Liquid crystal display (liquid crystal display, LCD) has the advantages of low radiation, small size and low energy consumption, and has gradually replaced the traditional cathode ray tube display (cathoderay tube display, CRT), so it is widely used in notebook computers, personal digital assistants (personal digital assistant, PDA), flat-screen TV, or information products such as mobile phones. The driving method of the traditional liquid crystal display is to use the source driver circuit (source driver) and the gate driver circuit (gate driver) to drive the pixels on the panel to display images. Since the cost of the source driver circuit is higher than that of the...

Even if the two types of pixel units PXL and PXR have the same design, it is easy to cause different performances due to process offsets (for example, the offset of the first metal layer Metal1 and the second metal layer Metal2 will cause the pixel units PXL and PXR to have different CGD ), will still produce different sizes of feedthrough voltage VFD

In the prior art driving method shown in Fig. 2 and Fig. 3, the gate cross-voltage is reduced by the same magnitude, although the effect of the feed-through voltage can be reduced, but the feed-through voltage of each pixel unit will still be different, so it cannot be effectively Eliminate screen flickering by adjusting the common voltage Vcom
