Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a repair method thereof, and a liquid crystal display device. Background technique [0002] With the rapid development of electronic products, consumers have higher and higher requirements for energy-saving products. For display panel manufacturers, the production of low-power consumption products has become a major challenge for them. In order to reduce the power consumption of liquid crystal display devices, the following solutions are usually adopted: 1. Increase the transmittance and reduce the power consumption of the backlight; 2. Use liquid crystal materials with high dielectric constants to reduce the panel driving voltage; 3. Use DC drive 4. Design a new pixel structure to reduce the liquid crystal operating voltage, thereby reducing panel power consumption. [0003] However, the above methods have the following problems: the improveme...

AI Technical Summary

Problems solved by technology

[0003] However, the above methods have the following problems: the improvement of transmittance is limited by resolution, color resistance materials, etc.; the current operating voltage of liquid crystal is already low, and it is difficult to lower it; the design of traditional AC common voltage drive (AV Vcom) Unable to perform column inversion and dot inversion, poor quality

[0004] According to p=1 / 2fcv 2 , P is the power, f is the refresh frequency, c is the capacitance, and v is the voltage. It can be seen that the power consumption of the liquid crystal display device is proportional to the refresh frequency, so the refresh frequency can be reduced to save power consumption when the picture is static, such as from 60HZ to 30HZ, but if the storage capacitor (Cs) of the liquid crystal display device is too small, there will be display problems such as flickering
