Abstract

The embodiment of the invention provides a correction method of an LED display screen and a related device. The method comprises the following steps: calculating to obtain a point-by-point thermal compensation correction coefficient according to the thermal compensation correction coefficient and the point-by-point correction coefficient of an LED display screen box body; and correcting the LED display screen box body according to the point-by-point thermal compensation correction coefficient. According to the method and the device provided by the invention, the thermal compensation correction coefficient and the point-by-point correction coefficient are separately stored, and one-time correction is carried out after the point-by-point thermal compensation correction coefficient is calculated according to the thermal compensation correction coefficient and the point-by-point correction coefficient; the invention solves the problem that due to the fact that the position of the LED display screen module is changed, thermal compensation correction cannot achieve the expected effect; besides, the separated thermal compensation correction coefficient only needs to be collected once for an LED display screen box of the same structure and PCB layout, and the correction efficiency is greatly improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a calibration method and a related device for a light emitting diode (light emitting diode, LED) display screen. Background technique [0002] With the rapid development of modern industrial technology, LED display has gradually been widely used in people's life and industrial production process. The LED display is not only easy to manufacture, but can maintain normal work in various environments, and the LED display has the characteristics of high resolution, wide viewing range, long viewing distance, and large area. LED displays are usually used in outdoor advertising, commercial display, stage rental, data visualization and other fields. In the LED display control system, the LED display is a flat-panel display spliced ​​by small LED modules or LED cabinets, which is used to display various information such as text, images, and videos. Each LED box includes a rece...
