Embodiment Construction

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

[0018] Specifically, a method for correcting brightness and chromaticity of an LED display screen 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 screen includes a plurality of LED display modules spliced ​​together, and each LED display module includes a plurality of pixels. The plurality of LED display modules can be taken from the same batch, or from different batches; a single pixel includes one or more LEDs, and in the case of multiple LEDs, for example, it includes red ( R), green (G), and blue (B) three-color LEDs, may even include white (W) LEDs or yellow (Y) LEDs, and of course may only include two-...

Abstract

The invention provides a method for correcting a bright color degree of an LED display screen. The method comprises the steps that the bright color degree data of a first LED display module and the bright color degree data of a second display module are read, and the bright color degree data of the first LED display module and the bright color degree data of the second LED display module are stored in a memorizer of the first LED display module and a memorizer of the second LED display module respectively or are connected with the recognition number of the first LED display module and the recognition number of the second LED display module respectively to be stored in a database; the read bright color degree data of the first LED display module and the read right color degree data of the second LED display module are analyzed to obtain the common bright color degree value of the first LED display module and the second LED display module, and the bright color degree correction target value of the LED display screen is set according to the common bright color degree value; the pixel point correction coefficient of the first LED display module is calculated according to the read bright color degree data of the first LED display module and the bright color degree correction target value. The correction coefficient can be generated on site without on-site collection.

Description

technical field [0001] The invention relates to the technical field of display correction, in particular to a method for correcting brightness and chromaticity of an LED display screen. 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] At present, the LED display industry usually adopts the method of adjusting the brightness and chromaticity of LED displays spliced ​​by single (multiple) production batches of LED lamp boards or LED cabinets, which is to correct the LED display screens at the calibration site through image acquisition equipment. The brightness and chromaticity information is collected, and the collected image is imported into the correction software for processing and a correction coefficient is generated...
