Abstract

The invention discloses a display driving method and electronic equipment. The display driving method comprises a step of obtaining image data outputted to an OLED display screen by a display card at different times according to a preset period, a step of accumulating the image data and storing accumulated image data, a step of executing a screen protection display instruction and generating a screen protection image based on the accumulated image data, and a step of driving the OLED display screen to display the screen protection image, wherein the screen protection image is used for reducing the difference of light emitting intensity decay of a pixel unit. In the technical scheme, the screen protection image is formed through driving the OLED display screen, the difference of light emitting intensity decay of the pixel unit in the OLED display screen is reduced, thus the image residual degree of the OLED display screen can be reduced, and the image display quality is improved.

Description

technical field [0001] The present invention relates to the technical field of display driving, and more specifically, to a display driving method and electronic equipment. Background technique [0002] With the continuous advancement of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable essential tool. [0003] The main part of electronic equipment to realize the display function is the display screen. LCD display and OLED display are the two mainstream displays today. OLED display has many advantages such as high color, wide viewing angle, high contrast, high response speed, light and thin, and low power consumption. It is regarded as the next generation of advanced display device after LCD. It has been widely used on the Internet, and it is also expected to be widely used in electronic devices such...
