Problems solved by technology

[0003] The current production of LED light boards and LED cabinets is only assembled or calibrated in the factory. There is no original brightness and chromaticity information stored on each LED light board or LED cabinet, so that if you need to obtain LED lights later The original brightness and chromaticity information of the board or LED cabinet is more troublesome

Embodiment Construction

[0017] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific implementations of the present invention will be described in detail below.

[0018] Specifically, a method for collecting and storing brightness and chromaticity information of an LED display module proposed by an embodiment of the present invention includes, for example, the following steps S1 to S3, and each step will be described in detail later. Wherein, the LED display module includes a plurality of pixels, and a single pixel includes one or more LEDs. In the case of a plurality of LEDs, it includes red (R), green (G), blue (B) Three colors of LEDs may even include white (W) LEDs or yellow (Y) LEDs, and of course only two colors of LEDs may be included.

[0019] Steps S1 to S3 of the method for collecting and storing brightness and chromaticity information of an LED display module according to an embodiment of the present invention will be...

Abstract

The invention provides a bright chroma information collecting and storing method for an LED display module. The method comprises the steps of controlling the LED display module to display a plurality of different-color pictures, collecting the different-color picture to obtain bright chroma information of the LED display module, and storing the bright chroma information of the LED display module into a storer of the LED display module. The method can collect and store the original bright chroma information of the LED display module like the LED lamp panel or the LED box body before the LED display module leaves a factory. Thus, when the original bright chroma information is needed to correct or restore color, the original bright chroma information can be conveniently and quickly obtained. In addition, if the original bright chroma information is stored in a database, the original bright chroma information cannot be lost when the storer on the LED lamp panel or the LED box body is damaged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for collecting and storing brightness and chromaticity information of an LED display module. Background technique [0002] As a new type of display technology, LED display has gradually been accepted by the market due to its advantages of energy saving, environmental protection, and high brightness, and has been widely used in urban media, urban traffic electronic signage and other fields. [0003] The current production of LED light boards and LED cabinets is only assembled or calibrated in the factory. There is no original brightness and chromaticity information stored on each LED light board or LED cabinet, so that if you need to obtain LED lights later The original brightness and chromaticity information of the board or LED cabinet is more troublesome. Contents of the invention [0004] Therefore, in order to overcome the technical problems existing in the prior ...
