Display screen, display algorithm, display data processing method and current adjusting method

Abstract

The invention relates to a display screen, a display algorithm, a display data processing method and a current adjusting method. The pixel point comprises first, second and third primary color light sources and a constant current source. The display time of the first, second and third primary color light sources is not overlapped. Each display cycle period is divided into a plurality of periods, and each period is divided into first, second and third sub-time units. The display time of the first primary color light source is only distributed in the first sub-time unit. Meanwhile, the display time of the second primary color light source is only distributed in the second sub-time unit, and the display time of the third primary color light source is only distributed in the third sub-time unit.

Description

technical field [0001] The invention mainly relates to the field of lighting display, more specifically, to providing a corresponding display screen, display algorithm, display data processing method and current adjustment method in the lighting display application scene containing three primary color light emitting diodes. Background technique [0002] In the field of lighting display, pulse dimming needs to adjust the time width of the diode to turn on or off within a certain period of time, and consider that the current flowing through the diode during the on-lighting period of the light-emitting diode is a fixed value, so as to realize the brightness change. As the performance requirements of the display screen are getting higher and higher, for example, high-speed cameras are popular in the industry to capture wonderful screen actions, then a display screen with a higher refresh rate is required to cooperate with it during playback. The refresh rate of the display scree...

Problems solved by technology

The traditional frequency increase mode usually requires the use of more complex logic circuits to break up the long turn-on lighting time

In the case of a display screen with a huge number of built-in pixels, the complex circuit not only leads to the disadvantage of error-prone logic operations, but also consumes too much power and generates a lot of heat. The most intuitive external performance of the display screen is the light-emitting diode. There are low-quality display effects such as flickering and incorrect display content

Furthermore, in the color mixing scene of multi-primary color LED light source, even if the up-frequency mode is adopted, it is difficult to flexibly allocate the conduction time of each primary color in each pixel and freely allocate the power of each primary color light source. There are defects in the fineness of color changes of pixels and the fidelity of image changes, and the image processing capabilities of current technical conditions need to be improved urgently
