Embodiment Construction

[0026] The following describes the embodiments of the present application in detail.

[0027] Electronic devices may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (UserEquipment, UE), mobile station (Mobile Station, MS), terminal device (terminal device) and so on.

[0028] The electronic device includes a screen, an application processor (Application Processor, AP) and a bus (Bus). The AP is connected to the bus, and the AP includes a distributed processing unit (Distributed Processing Unit, DPU). The DPU includes N layer hardware, a layer mixer (layer mix), a display post processing (Display post processing, DSPP) and a display serial interface (display serial interface, DSI). The N layers of hardware include first layer hardware and M second layer hardware, N is an integer greater than 1,...

Abstract

The invention discloses a display brightness adjustment method and related equipment. The method comprises: applying to an electronic device comprising a screen and a DPU, the DPU comprising N layer hardware and layer mixers, the N layer hardware comprising first layer hardware and M second layer hardware, N being an integer larger than 1, M being smaller than N, and each layer hardware being connected with the layer mixers. The method comprises the following steps: when an adjustment instruction for the backlight brightness of the screen is detected, setting the backlight brightness value ofthe screen as a first threshold value, then modifying the first layer to reduce the brightness of the first layer, then superposing the modified first layer with a plurality of second layers to obtaina third layer, and finally displaying the third layer through the display screen. By adopting the embodiment of the invention, the screen flickering effect can be reduced.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a display brightness adjustment method and related equipment. Background technique [0002] At present, the method of adjusting the gray level of the screen in the range of 0-256 is different from that in the range of 257-1024. Adjusting within the range of 257 to 1024 is to adjust the voltage, while adjusting within the range of 0 to 256 is to adjust the duty cycle of the power supply. At present, the frequency band set when adjusting the power supply duty cycle is 480Hz, and since 480Hz is a low frequency band that is easily perceived by human eyes, it produces a flickering effect on the screen. Contents of the invention [0003] Embodiments of the present application provide a display brightness adjustment method and related equipment to reduce the flickering effect of the screen. [0004] In the first aspect, the embodiment of the present application provide...
