Pixel structure of liquid-crystal display device and liquid-crystal display device

Abstract

The invention discloses a pixel structure of a liquid-crystal display device. The pixel structure comprises a plurality of scanning lines, a plurality of data lines and a plurality of pixel units, wherein the plurality of scanning lines are arranged in parallel; the plurality of data lines are arranged along the direction vertical to the scanning lines; the plurality of pixel units are defined by the crossed scanning lines and data lines; each pixel unit comprises a liquid-crystal capacitor, a first transistor and a second transistor; the first transistor and the second transistor are connected in series; and the second transistor is coupled to the liquid-crystal capacitor. The pixel structure is characterized in that any scanning line is connected with the first transistor in the pixel unit positioned at one side of the scanning line, and is also connected with the second transistor in the pixel unit positioned at the other side of the scanning line. The invention also discloses the liquid-crystal display device. The pixel structure disclosed by the invention has the advantages that the transistors at different positions in two adjacent pixel units are directly connected to any scanning line, and the quantity of the scanning lines is reduced by a half, so that not only is the space saved, but also the area of the storage capacitor can be increased or the pixel size can be reduced, and the PPI and the display effect can be improved.

Description

technical field [0001] The invention relates to the technical field of pixel structures, in particular to a pixel structure for a liquid crystal display device and the liquid crystal display device. Background technique [0002] With the continuous development of LCD technology, in order to further reduce LCD power consumption, a new type of ultra-low frequency liquid crystal display has emerged. In order to reduce the loss of leakage current in the TFT transistor and increase the time for the storage capacitor to maintain the display, two transistors are arranged in one pixel. [0003] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of the circuit principle of the existing novel dual-transistor pixel structure. The left and right ends of the pixel structure lead out from the data lines 2', and the lower end leads out from the scan lines 1'; the pixel structure specifically includes a plurality of scan lines 1' and a plurality of data lines 2' arranged in a...

[0004] However, the existing double-transistor pixel structure contains two scanning lines in each pixel unit and is connected to two transistors respectively. Compared with the existing single-transistor pixel structure, the number of scanning lines is doubled, and corresponding Reduce the storage capacitor area or increase the pixel size, but also increase the load impedance and parasitic capacitance, which greatly affects the display effect
