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 flicke...

Embodiment Construction

[0180] The solution of the present invention will be clearly and completely described below with reference to each embodiment. The solutions obtained by those skilled in the art without creative work all belong to the protection scope of the present invention.

[0181] see figure 1 , and many cascaded pixels are arranged in one or more columns on the power supply path. The power input terminal of the first pixel point PX1 at the head of each column is coupled to the positive power supply VP, and correspondingly, the potential reference terminal of the last pixel point PXN as the tail of the column is coupled to the negative power supply VN. In each column, the power input terminal of the next pixel is also set to be coupled to the potential reference terminal of the previous pixel. In the illustrated embodiment, for example, in the first column, the current inflow terminal of the second pixel point PX2, that is, the power input terminal, is coupled to the current outflow ter...

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...
