Problems solved by technology
At present, the technology for correcting LED displays is gradually becoming mature, but the brightness and chromaticity correction method for virtual pixel LED displays is still under development.
Since the virtual pixel involves the sharing of physical light points in the LED display screen, the display method of the virtual pixel is more complicated, and the common correction method cannot be applied to the virtual pixel LED display screen. It can be seen that the existing technology cannot guarantee that the virtual pixel LED The correction effect of the display

Embodiment Construction
[0065] The specific implementation manners disclosed by the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0066] figure 1 is a flowchart of a method for correcting virtual pixels according to an exemplary embodiment, as shown in figure 1 As shown, the method includes:
[0067] In step 101, according to the preset virtual pixel division strategy, the physical light points on the LED display screen are divided into several virtual pixels, and it is determined that each physical light point in the virtual pixel is divided into the virtual pixel and the adjacent virtual pixels. Number of times shared.
[0068] For example, virtual pixels specifically refer to the 1:N (N=2X2) relationship between the number of physical pixels (that is, actua...

The invention relates to a virtual pixel correction method and device, and the method comprises the steps: dividing a physical lamp point on an LED display screen into a plurality of virtual pixels according to a preset virtual pixel division strategy, and determining the number of times that each physical lamp point in the virtual pixels is shared in the virtual pixel and the adjacent virtual pixels; determining an initial tristimulus value of each virtual pixel according to the tristimulus value of each physical lamp point in the virtual pixel and the number of times that the physical lamp point is shared; determining a target correction coefficient corresponding to each virtual pixel according to a preset target tristimulus value and the initial tristimulus value of each virtual pixel; and performing brightness correction and / or chromaticity correction on the virtual pixel corresponding to the target correction coefficient through each target correction coefficient. The correction problem of the virtual pixel LED display screen can be solved, the display effect of the LED display screen is remarkably improved, the operation is simple, and no redundant operation is needed.
Description
technical field [0001] The disclosure of the present invention relates to the technical field of virtual pixel display effects, and in particular, to a virtual pixel correction method and device. Background technique [0002] The calibration of the LED display can play an important role in the later maintenance and significantly improve the uniformity of the brightness and chromaticity of the LED display. At present, the technology for correcting LED displays is gradually becoming mature, but the brightness and chromaticity correction method for virtual pixel LED displays is still under development. Since the virtual pixel involves the sharing of physical light points in the LED display screen, the display method of the virtual pixel is more complicated, and the common correction method cannot be applied to the virtual pixel LED display screen. It can be seen that the existing technology cannot guarantee that the virtual pixel LED The correction effect of the display. Ther...
