Problems solved by technology

Therefore, as time goes by, the OLED material will age, such as its luminosity will gradually decrease, and there will be chromatic aberration, etc., and because the decay rates of the red, green, and blue light-emitting materials are often different, this leads to OLED displays. uneven brightness

Abstract

Embodiments of the invention disclose a pixel call method and a pixel call device. The method comprises the following steps: counting the on-time of the display screen of a terminal, and detecting whether the counted on-time exceeds a preset time threshold; if the counted on-time exceeds the preset time threshold, determining a target standby pixel point associated with the time threshold from at least one standby pixel point; and using the target standby pixel point to replace a target sub pixel point in a screen pixel, and calling the target standby pixel point to emit light. By implementing the embodiments of the invention, the luminance and chrominance of an OLED can be compensated through a preset standby pixel point.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a pixel calling method and device. Background technique [0002] At present, Organic Light-Emitting Diode (OLED) is an emerging application technology of flat-panel displays. Due to its self-luminous characteristics, no need for backlight source, energy saving, large viewing angle and other advantages, it has been used in mobile phones. , digital cameras, tablet PCs and televisions are widely used in terminals. [0003] Among them, OLED light-emitting materials are composed of three primary colors, including red, green and blue light-emitting materials. Since OLED is self-luminous, its light-emitting process is the process of continuous consumption of OLED materials. Therefore, as time goes by, the OLED material will age, such as its luminosity will gradually decrease, and there will be chromatic aberration, etc., and because the decay rates of the red, green, an...
