Display unit and spliced screen

Abstract

The embodiment of the invention discloses a display unit and a spliced screen. In a specific implementation mode, the display unit comprises a first side, a second side, a third side, a fourth side, awireless transmission module, a first short-distance wireless communication module, a second short-distance wireless communication module, a third short-distance wireless communication module and a fourth short-distance wireless communication module, wherein the first side and the second side are opposite to each other; the first short-distance wireless communication module and the third short-distance wireless communication module are used for transmitting a wireless signal carrying the unique identification code of the display unit; the second short-distance wireless communication module and the fourth short-distance wireless communication module are used for receiving wireless signals transmitted by other display units; and the wireless transmission module is used for sending the unique identification code of the display unit, the azimuth information of other display units adjacent to the display unit and the unique identification codes of other adjacent display units to the splicing controller. Based on the display unit of the embodiment, the splicing controller can accurately and conveniently identify and position each display unit in the splicing screen.

Description

technical field [0001] This application relates to the field of display technology. More specifically, it relates to a display unit and a splicing screen. Background technique [0002] With the development of the electronics industry, display screens are being used more and more in education, security, medical care, business, etc. The production technology is very mature, the product yield rate is high, the production cost is relatively low, and the market acceptance is high. At present, the demand for various super-sized display screens is increasing day by day, and its applications are becoming more and more extensive. Due to technological limitations, the integrated production process of super-large display screens is difficult and costly. It has become the best choice for super large screen display. The splicing screen can not only combine multiple units into a large screen, but also use one of the units to display independently, which has high flexibility. [0003] A...
