Abstract

The invention discloses a brightness adjusting method of a light-emitting panel, the light-emitting panel and a display device, and belongs to the technical field of display, the light-emitting panel comprises a substrate and a light-emitting unit arranged on the substrate, and the light-emitting panel further comprises a control circuit and a plurality of signal lines arranged on the substrate, the control circuit comprises a data signal input end, a data storage module and a plurality of first signal ends. The data storage module is used for storing first voltage signals and first pulse width modulation signals corresponding to different gray-scale values. Each signal line connects one light-emitting unit with a first signal end; the brightness adjusting method comprises the following steps: acquiring a to-be-luminous picture, and determining different gray-scale values corresponding to each luminous unit in the to-be-luminous picture; and calling a first pulse width modulation signal and a first voltage signal corresponding to each gray-scale value in the data storage module according to different gray-scale values. The display device comprises the light-emitting panel. According to the invention, fine dimming can be realized, and the high-resolution display requirement is met.

Description

technical field

[0001] The present invention relates to the field of display technology, and more particularly, to a method for adjusting the brightness of a light-emitting panel, a light-emitting panel and a display device. Background technique

[0002] With the advent of the era of ultra-high-definition display, higher requirements are placed on display quality and resolution. LED (Light-Emitting Diode) display technology has shown a higher More excellent performance, therefore, Mini / Micro LED is the most promising new display technology in the display field.

[0003] Usually, a Mini / Micro LED display device is provided with a plurality of light-emitting elements and signal lines connected to the light-emitting elements, through which the light-emitting elements can receive signals to perform light-emitting display. The light-emitting element also has a transistor connected to each light-emitting element as a switch. By outputting different pulse width modulation (PWM, Pu...
