Embodiment Construction

[0030] Please refer to figure 1 , figure 1 Showing a display panel according to an embodiment of the present invention is a block diagram. Please refer to figure 2 , figure 2 A block diagram of a display panel according to an embodiment of the present invention is shown. The display panel 100 includes a plurality of pixel circuits P11 -Pxy, a plurality of horizontal signal lines HL1 -HLx, a plurality of vertical signal lines VL1 -VLy and a control chip 110 . The pixel circuits P11 ˜ Pxy are configured as x rows and y columns, where x and y are positive integers. Each row of pixel circuits is coupled to the control chip 110 through a corresponding horizontal signal line. The pixel circuits of each column are coupled to the control chip 110 through corresponding vertical signal lines. The pixel circuits are also divided into two groups. The first group and the second group of pixel circuits respectively include multiple rows of pixel circuits, wherein the row belonging ...

Abstract

The invention discloses a display panel and an operation method thereof. The display panel includes a plurality of pixel circuits. The pixel circuits are configured into a first group and a second group. A first contact of the first group of pixel circuits receives a first power supply voltage, and a second contact receives a second power supply voltage. The first contact of the second group of pixel circuits receives the second power supply voltage, and the second contact receives the first power supply voltage. During a first time period of a frame, a second power supply voltage is pumped and loaded to perform data writing on the first group of pixel circuits, and the second group of pixel circuits emit light by taking the first power supply voltage as a reference voltage. And during a second time period of the frame, the first power supply voltage is pumped and loaded to perform data writing on the second group of pixel circuits, and the first group of pixel circuits emit light by taking the second power supply voltage as a reference voltage.

Description

technical field [0001] The invention relates to a display panel and an operating method thereof. Background technique [0002] The resolution of display devices is increasing day by day. The improvement of the resolution means the increase of the scanning line (SCAN line). For high-resolution display devices, there are still some practical problems in the progressive scanning driving method. For example, current division affects optical effects, signal voltage conversion loading, and other issues. Therefore, it is necessary to improve the high-resolution display device and its driving method. Contents of the invention [0003] An embodiment of the invention discloses a display panel, which includes a plurality of pixel circuits. The pixel circuits are arranged in a plurality of rows and a plurality of columns, and the pixel circuits in some rows are arranged in a first group, and the pixel circuits in the remaining rows are arranged in a second group, and each pixel ci...
