1. Field of the Invention
The invention relates in general to an electronic device, and more particularly to a liquid crystal display and a gate driver thereof.
2. Description of the Related Art
Because a liquid crystal display (LCD) apparatus has the low power consumption, the low generated heat, the light weight and the non-radiative property, LCD apparatuses are used in various electronic products, and gradually replace the conventional cathode ray tube (CRT) display apparatuses. The liquid crystal molecule of the LCD apparatus possesses a property that the liquid crystal molecule cannot be always driven by the same voltage with the same polarity, or otherwise the property of the liquid crystal molecule is damaged after a long time and cannot rotate in response to the variation of the electric field even if the voltage is cancelled. Thus, the polarity of the voltage must be changed every other period of time to prevent the property of the liquid crystal molecule from being damaged.
At present, the frequently seen liquid crystal display panels may be classified into a normal pixel array and a flip pixel array. The polarity of the normal pixel array is switched by way of 1+2 line inversion, while the polarity of the flip pixel array is switched by way of column inversion. However, the flip pixel array has the smaller aperture ratio, while the polarity switching of the 1+2 line inversion has the higher power consumption. Thus, it is a very important subject to consider the high aperture ratio and the low power consumption.
