Abstract

The embodiment of the invention discloses a display screen scanning method and a display screen, which realizes the scanning method of an odd-numbered LED display screen and solves the problem that the existing dynamic scanning is an even-numbered scanning method, which cannot be applied to an even-numbered form. At the same time, it avoids the technical problem of prolonging the man-hours of manufacturing the cabinet of the display module, and ensures the safety of the product and the reliability of the device. The method in the embodiment of the present invention includes: S1: determining that the scanning base of the display module is an odd number; S2: dividing the scanning base into a plurality of scanning groups containing an odd group according to the odd number; S3: performing a scan on the display module according to the scanning base of the scanning group corresponding scan.

Description

technical field [0001] The invention relates to the technical field of display screen scanning, in particular to a display screen scanning method and a display screen. Background technique [0002] Large-scale LED screens, such as LED splicing screens, are composed of several display modules, and each display module is mounted or welded with a number of LED particles in the form of rows. When the LED screen is working for display, it is necessary to statically The scanning method of scanning or dynamic scanning is used for driving, and usually the LED screen uses dynamic scanning. [0003] At present, the dynamic scan is usually an even-numbered scan, such as constant current 1 / 2 scan, 1 / 4 scan, 1 / 8 scan, 1 / 16 scan, which can be understood as 2-line scan, 4-line scan, and 8-line scan , 16-line scan mode. [0004] However, the above-mentioned dynamic scanning is usually an even-numbered scanning method. When the size of the LED substrate is fixed, the LED board with a certa...
