Abstract

Embodiments of the present application provide a dimming method and device for an OLED display screen applied to two-dimensional code scanning. In this method, after the terminal device detects that the two-dimensional code appears on the display interface, it increases the light-on time of all pixels in the area used to display the two-dimensional code, so that the light-off time of each pixel is shortened. When the scanning device scans the QR code displayed by the terminal device, at least all pixels in the area where the QR code is located will maintain a short extinguishing time to ensure that most of the pixels read by the scanning device can be in the In the lighted state, the number and width of black diagonal lines can be reduced, or even eliminated, so that the scanning device can quickly identify the QR code, improving the recognition efficiency and accuracy. In addition, when it is detected that the QR code on the display interface is turned off, the lighting time of the target pixel is restored to the initial lighting time, so that the full-screen brightness of the display screen is restored to adapt to the ambient brightness, and the power consumption of the display screen is reduced.

Description

technical field [0001] The present application relates to the technical field of display control, in particular to a dimming method and device for an OLED display screen applied to two-dimensional code scanning. Background technique [0002] Organic Light-Emitting Diode (OLED) display screens can individually light up and control each pixel, and have the advantages of clear black and white and high color saturation, so more and more terminal devices use OLED display screens. [0003] The terminal device can automatically adjust the brightness of the OLED display, so that users can normally watch the content on the display under different light conditions. At present, terminal equipment generally adopts the PWM dimming mode to change the brightness of the display screen. The PWM dimming mode makes each pixel continuously flash on and off according to the predetermined dimming frequency. It will think that the screen is always on. The pixels flicker on and off once in a dimm...
