Embodiment Construction

[0036] In order to further illustrate the display brightness adjustment module, adjustment method, and display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0037] An embodiment of the present invention provides a display brightness adjustment method, which is applied to a light emission control circuit. The light emission control circuit is used to generate a light emission control signal EM for controlling the display device to emit light. The display brightness adjustment method includes: when the display brightness of the display device is not at the predetermined brightness When within the range, adjust the duty cycle of the light emission control signal EM, so that the brightness of the display device is within the predetermined brightness range.

[0038] Specifically, the specific structures of the existing light-emitting control circuits are various, and generally ...

Abstract

A method of adjusting display brightness, a light-emission control circuit and a display device are provided. A method of adjusting display brightness is applied to an light-emission control circuit, where the light-emission control circuit is configured to generate an light-emission control signal configured to control a light-emission of a display device. The method includes: adjusting, in the case that a display brightness of the display device is not within a predetermined brightness range, a duty ratio of the light-emission control signal, to enable the display brightness of the display device to fall into the predetermined brightness range.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display brightness adjustment module, an adjustment method, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device has many advantages such as self-illumination, ultra-thin, fast response speed, high contrast ratio, wide viewing angle, etc., and is a display device that has attracted extensive attention at present. [0003] When the OLED display device is working, the driving circuit drives the light-emitting element to emit light, thereby realizing the display function of the OLED display device. However, during the working process of the driving circuit, the thin film transistor included in it is prone to electric leakage, which causes the display brightness of the OLED display device to decrease within a display time of one frame, thus making it easy for human eyes to observe flickering display im...
