Embodiment Construction

[0042] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. In the description of the present application, terms such as "first", "second", "third" and the like are only used to distinguish the description, and should not be construed as indicating or implying relative importance or sequence.

[0043] As mentioned above, the LED display screen usually has uneven chromaticity, so how to correct the chromaticity of the LED display screen is a technical problem to be solved in this application.

[0044] For example, in practical applications, an LED display usually includes a circuit board and a plurality of light-emitting LED lamp beads that are fixed on the circuit board in an array. These LED lamp beads may easily cause uneven chromaticity of the LED display when emitting light due to different structures during packaging or inconsistent attenuati...

Abstract

The invention provides a chromaticity correction method and device of an LED display screen and electronic equipment. The method comprises the following steps: determining an actual chromatic value of a target lamp bead in a to-be-corrected LED display screen when the target lamp bead is displayed in a primary color; determining a correction coefficient according to the actual chromatic value and a reference chromatic value of the primary color; and correcting the chromaticity of the primary color light emitted by the target lamp bead in the to-be-corrected LED display screen by using the correction coefficient. Therefore, the chromaticity of the to-be-corrected LED display screen can be corrected, and the phenomenon that the chromaticity of the LED display screen is not uniform is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a method, device and electronic device for chromaticity correction of an LED display screen. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the application of LED (Light Emitting Diode) displays is becoming more and more extensive. In practical applications, the LED display screen usually has uneven chromaticity, so how to correct the chromaticity of the LED display screen is a technical problem to be solved in the present application. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a method, device and electronic device for chromaticity correction of an LED display screen, which are used to solve the problems in the prior art. [0004] A first aspect of the embodiments of the present application provides a chromaticity corre...
