Example Embodiment

[0015] The present invention will be described in detail below in conjunction with examples. The examples are only preferred embodiments of the present invention and are not intended to limit the present invention.

[0016] The existing two-transistor pixel structure design has limited space in the pixel, and in order to reduce the refresh frequency as much as possible, the storage capacitor must be increased as much as possible to maintain the picture for a longer time; but the existing two-transistor pixel structure contains Two scan lines are connected to two transistors respectively, and the number of scan lines is doubled compared with the existing single-transistor pixel structure. The area of ​​the storage capacitor needs to be reduced accordingly, but the storage capacitor will be reduced and the stored power will be insufficient In order to maintain the display to the next pixel charging time; or correspondingly increase the pixel size but reduce the PPI, reducing the sam...

Abstract

The invention discloses a pixel structure of a liquid crystal display device. Each pixel unit includes a liquid crystal capacitor and a first transistor and a second transistor connected in series, and the second transistor is coupled to the liquid crystal capacitor; it is characterized in that any one of the scanning lines and the pixel located on one side thereof The first transistor in the unit is connected to the second transistor in the pixel unit on the other side thereof. The invention also discloses a liquid crystal display device. In the pixel structure of the liquid crystal display device of the present invention, by directly connecting transistors located at different positions in two adjacent pixel units on any scan line, the number of scan lines is reduced by half, which not only saves space, but also increases storage capacitance Area or reduce the pixel size, increase the PPI, and improve the display effect.

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...
