Abstract

The invention relates to a liquid crystal display device and a drive method thereof. The liquid crystal display device comprises a plurality of pixel units, wherein each pixel unit comprises a first transistor, a second transistor, a reflection plate and a storage capacitor. The channel width-length ratios of the first transistor and the second transistor are larger than 12 / 5; the reflection plate is arranged in a position close to the transistors to reflect the environment light; and the storage capacitor is arranged in a position overlapping that of the reflection plate and the capacity thereof is larger than 1 pF.

Description

technical field [0001] The invention relates to a liquid crystal display device capable of effectively reducing power consumption and a driving method thereof. Background technique [0002] figure 1 It is a schematic diagram of a conventional reflective thin film transistor liquid crystal display (reflective type TFT LCD). like figure 1 As shown, in the reflective thin film transistor liquid crystal display 100 , the thin film transistor T and the storage capacitor Cst can be formed by using a stack structure including a first metal layer M1 and a second metal layer M2 . The reflective plate 104 disposed on one side of the array substrate 102 can reflect the ambient light I1 to save power. figure 2 It is a schematic diagram of an existing transflective type TFT LCD. like figure 2 As shown, in the transflective thin film transistor liquid crystal display 200 , each pixel area has a transmissive area and a reflective area at the same time, and the reflective area is for...
