Embodiment 1

[0054] On the basis of the foregoing embodiments, in one embodiment of the present application, as Image 6 as shown, Image 6 A schematic structural diagram of a display panel provided by an embodiment of the present application; in this embodiment, the first control circuit 100 includes: a first control switch M1, a first terminal of the first control switch M1 and a first data signal input terminal S10 is electrically connected, the second terminal is electrically connected to the first data line S1, and the control terminal is electrically connected to the first control signal input terminal SW1; in the first time period, the first control signal input terminal SW1 inputs a conduction level to control the first control signal input terminal SW1. A control switch M1 is in a conducting state, so as to transmit the first data voltage input from the first data signal input terminal S10 to a plurality of devices electrically connected to the first data line S1 through the first...

Embodiment 2

[0076] The difference from Embodiment 1 is that in the display panel provided in the embodiment of the present application, the specific implementation manner of the second control circuit is different.

[0077] Specifically, in one embodiment of this application, as Figure 10 As shown, the first control circuit includes: a first control switch M1, the first end of the first control switch M1 is electrically connected to the first data signal input end S10, the second end is electrically connected to the first data line S1, and the control end is electrically connected to the first data signal input end S10. The first control signal input terminal SW1 is electrically connected; in the first time period, the first control signal input terminal SW1 inputs a conduction level, and controls the first control switch M1 to be in a conduction state, so that in the first time period, through the second A data line S1 transmits the first data voltage input from the first data signal in...

Embodiment 3

[0098] The difference from Embodiment 1 and Embodiment 2 above is that not all the sub-pixels electrically connected to the same data line are sub-pixels of the same color, that is, not all the sub-pixels electrically connected to the first data line S1 are the first sub-pixel. Such as Figure 13 as shown, Figure 13 A pixel arrangement diagram in a display panel provided by an embodiment of the present application.

[0099] Specifically, in the embodiments of this application, such as Figure 13 with Figure 14 as shown, Figure 14 A schematic structural diagram of a display panel provided in yet another embodiment of the present application; in this embodiment, the display panel further includes:

[0100] A plurality of second sub-pixels 2 electrically connected to the first data line S1;

[0101] The first control circuit includes:

[0102] The first control switch M1, the first end of the first control switch M1 is electrically connected to the first data signal inp...

Abstract

The embodiment of the present application discloses a display panel and its use method. When the display panel ages each light-emitting unit in its first sub-pixel, different inputs are given to a plurality of first sub-pixels electrically connected to the same data line. The data voltage input by the first sub-pixel that is closer to the power supply voltage terminal is larger, and the data voltage input by the first sub-pixel that is farther from the power supply voltage terminal is smaller, so as to offset some of the data voltages that are farther from the power supply voltage terminal. The input voltage of the power supply voltage terminal received by the first sub-pixel is smaller than the influence of the voltage input of the power supply voltage terminal received by the first sub-pixel closer to the power supply voltage terminal, thereby reducing the influence of the first sub-pixel farther from the power supply voltage terminal. The luminance difference between the pixel and the first sub-pixel close to the power supply voltage end during normal display improves the chromaticity uniformity of the display panel when displaying pictures.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a method for using the same. Background technique [0002] With the development of display technology, display screens are used more and more widely, and have gradually become an indispensable component of people's daily life. Correspondingly, with the popularization of display screens, people have higher and higher requirements for display quality. come higher.
