Embodiment Construction

[0017] see figure 1 , figure 1 It is a schematic circuit diagram of an embodiment of the pixel driving circuit of the present application. This embodiment includes a data line Data, a scan line Scan, a first pixel electrode 101 and at least two first switches T1, T2; the respective input terminals 102, 103 of the at least two first switches T1, T2 are connected to the data line Data, The respective output terminals 104, 105 of at least two first switches T1, T2 are connected to the same first pixel electrode 101, and the respective control terminals 106, 107 of at least two first switches T1, T2 are connected to the scanning line Scan, so as to speed up The charging process of the first pixel electrode 101.

[0018] In order to meet the user's higher and higher requirements for the fluency of the screen display, the frame rate of the screen display is also increasing, the period of the pixel scanning signal is getting smaller and smaller, and the continuous driving time of t...

Abstract

The invention discloses a pixel driving circuit, an array substrate and a display panel. The pixel driving circuit comprises a data cable, a scanning line, a first pixel circuit, and at least two first switches; the input ends of the at least two first input switches are all connected to the data cable, the respective output ends of the at least two first input switches are all connected to the same pixel electrode, the respective control ends of the at least two first switches are all connected with the scanning line so as to quicken the charging process of the first pixel electrode, and thus the problem that the display quality of a display image is lowered caused when the first pixel electrode is not charged sufficiently is solved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a pixel driving circuit, an array substrate, and a display panel. Background technique [0002] With the development of display technology, people's demand for high-definition and realistic display pictures of liquid crystal display panels is becoming more and more common, especially the high-fidelity pictures of 3D display technology are more and more popular among film and television audiences. In the liquid crystal display panel technology driven by switches, such as thin film transistors (Thin Film Transistor, TFT), the frame rate is the number of frames that drive the display screen per second. The larger the frame rate, the more screens can be displayed per unit time. The screen display will be smoother. [0003] However, as the frame rate increases, the charging time of the switch to the pixel electrode will be reduced accordingly, which will lead to the ...
