Embodiment Construction

[0035] The technical solution of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0036] It should be noted that, compared with the prior art, the display screen provided by the embodiment of the present application adds a comparator between two pixels, and the comparator can compare the driving signal output by one of the pixels with the undelayed Compared with the driving signal at the time, and output the undelayed signal, the undelayed signal can be input into another pixel and drive the pixel. In this way, since the...

Abstract

The invention discloses a display screen, a pixel driving method and a display device. The display screen comprises at least one display unit. Each display unit comprises a first pixel, a second pixeland a comparator. A first input end of each comparator is connected with a driving signal output end of the corresponding first pixel. The driving signal output end of each first pixel is used for outputting first driving signals. A driving signal line is connected with a second input end of each comparator, and is used for providing second driving signals, namely non-delayed signals. An output end of each comparator is connected with a driving signal input end of the corresponding second pixel. The comparators are used for comparing the first driving signals with the second driving signals and outputting third driving signals, namely non-delayed signals. The third driving signals are used for driving the second pixels. The signals for driving the second pixels are the non-delayed signals, so that data can be written into the second pixels normally, and normal display of the display device can be guaranteed effectively.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display screen, a pixel driving method and a display device. Background technique [0002] An organic light-emitting display device is a display device that uses an organic light-emitting diode as a light-emitting device. It has the characteristics of high contrast, thin thickness, wide viewing angle, fast response speed, and low power consumption. It is increasingly used in various display and lighting applications. field. [0003] Generally, an organic light-emitting display device may include a driver and a plurality of pixels, each pixel may correspond to a pixel circuit, wherein the driver may generate a driving signal, and the driving signal may be transmitted in a plurality of pixel circuits, and each pixel circuit may be Scan and write data, so that the light-emitting diodes in the pixel circuits emit light, and the entire display device emits light. [000...
