Problems solved by technology

[0004] However, the typical common electrode is made of opaque metal, so when the electrode area of ​​the storage capacitor increases to increase the capacitance, the aperture ratio of the pixel area will decrease
In order to maintain the brightness of the liquid crystal display, it is necessary to increase the power of the backlight module, thus increasing the power consumption.
