Digital driving pixel circuit and method for digitally driving pixels

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a digital driving pixel circuit and a digital driving pixel method. The digital driving pixel circuit providedby the invention comprises a pixel driving module, a display module, a storage module and a short circuit module. The output end of the pixel driving module is electrically connected with the input end of the display module, and the control end of the pixel driving module is electrically connected with any output end of the storage module. The input end of the short circuit module is electricallyconnected with the input end of the display module, the output end of the short circuit module is electrically connected with the output end of the display module, and the control end of the short circuit module is electrically connected with any output end of the storage module. And under the condition that the level signal indicates that the display module is closed, the short circuit module isin short circuit with the input end of the display module and the output end of the display module. According to the embodiment of the invention, the level signal can accurately control the light-emitting assembly in the display screen to emit light, and the display effect of the display screen is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a digitally driven pixel circuit and a method for digitally driven pixels. Background technique [0002] OLED (Organic Light-Emitting Diode) is called an organic light-emitting diode, because it has many advantages, such as active light without a backlight source, wide viewing angle, fast response speed, high definition and contrast, wide operating temperature range, and can be realized With many advantages such as flexible display and large-area full-color display, it has been applied to televisions and monitors. In addition, Micro LED, as a solution for future display, has also become a hot spot in the research and development of the display field. [0003] At present, common pixel circuits are divided into analog driving pixel circuits and digital driving pixel circuits. However, analog driving pixel circuits have problems such as high circuit po...
