Problems solved by technology

However, as users have higher and higher requirements for picture quality and picture resolution, more and more conductive lines are arranged in the peripheral circuit area, and it is difficult to meet the design requirements of narrow borders. , so how to take into account the quality of the display screen and the design requirements of the narrow frame is actually the goal that those skilled in the art are eager to pursue.

Embodiment Construction

[0034] figure 1 It is a system diagram of a display panel according to an embodiment of the present invention. Please refer to figure 1 , in this embodiment, the display panel 100 includes, for example, a pixel array 110 and a gate driving circuit 120 . The pixel array 110 has a plurality of pixels PX, and these pixels PX are arranged in an array, for example. The gate driving circuit 120 is coupled to these pixels PX to provide a plurality of gate signals (such as G1-Gm), and the gate driving circuit 120 includes, for example, a plurality of shift registers (such as 121_1-121_x) and a plurality of demultiplexing devices (such as 123_1~123_x), where x is a positive integer, and m is a multiple of x (4 times here). And each shift register (such as 121_1-121_x) and the coupled demultiplexer (such as 123_1-123_x) can be regarded as a first-stage gate signal generation unit.

[0035] The shift registers 121_1~121_x respectively receive the start signal STV or the gate signal (...

Abstract

A display panel including a pixel array and a gate driver circuit is provided. The pixel array has a plurality of pixels. The gate driver circuit is used for providing a plurality of gate signals to the pixels and includes a plurality of shift registers and a plurality of demultiplexers. The shift registers respectively receive a first gate signal of the gate signals and a first clock signal of a plurality of clock signals to respectively provide a first control signal and a second control signal. The demultiplexers respectively receive a plurality of second clock signals of the clock signals, respectively turn-on according to the corresponding the first control signal, and respectively cut-off according to the corresponding second control signal. The display panel may reduce the number of transistors disposed on the gate driver circuit of the display panel to narrow the border of the display panel.

Description

technical field [0001] The present invention relates to a display panel, and in particular to a display panel with a gate driving circuit. Background technique [0002] With the evolution of optoelectronic and semiconductor technologies, flat panel displays have been widely used recently, and have replaced cathode ray tube (Cathode Ray Tube, CRT) displays as the mainstream of next generation displays. Taking a liquid crystal display panel as an example, it is mainly composed of an active element array substrate, an opposite substrate, and a display element sandwiched between the active element array substrate and the opposite substrate, wherein the active element array substrate has a plurality of pixels arranged in an array . For the sake of aesthetic appearance and special visual experience, a current trend is to make the display panel meet the design requirements of narrow bezels. However, as users have higher and higher requirements for picture quality and picture reso...
