The invention relates to a semi-penetration and semi-reflective liquid crystal display device and a driving method thereof. The semi-penetration and semi-reflective liquid crystal display device comprises a plurality of pixel units, wherein each pixel unit comprises a penetration region, a reflection region, a thin-film transistor, a coupling capacitor, a first liquid crystal capacitor and a second liquid crystal capacitor; the first liquid crystal capacitor comprises a first common electrode, a liquid crystal layer corresponding to the penetration region and a penetration electrode; the second liquid crystal capacitor comprises a second common electrode, a liquid crystal layer corresponding to the reflection region and a reflective electrode; the thin-film transistor is electrically connected with the first liquid crystal capacitor and is electrically connected with the second liquid crystal capacitor through the coupling capacitor; and the thickness of the liquid crystal layer corresponding to the penetration region and the thickness of the liquid crystal layer corresponding to the reflective region are substantially the same. The semi-penetration and semi-reflective liquid crystal display device has the advantages of simple fabrication process and low cost.
Description
technical field [0001] The invention relates to a semi-transmissive and semi-reflective liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices have been widely used in the fields of mobile phones, personal digital assistants, notebook computers, personal computers, and televisions due to their low radiation, small size, and low power consumption. With the maturity and innovation of related technologies, their The variety is increasing. [0003] According to different light sources used by the liquid crystal display device, the liquid crystal display device can be divided into a transmissive liquid crystal display device and a reflective liquid crystal display device. The transmissive liquid crystal display device must set a backlight on the back of the liquid crystal display panel to realize image display, however, the energy consumption of the backlight accounts for about half of the energy consumption of th...
