Display screen and assembly method thereof

Abstract

The invention relates to a display screen and an assembly method thereof. The display screen assembly method includes obtaining position information of a plurality of first preset positions on at least two display modules; detecting the first preset positions of two adjacent display modules Whether the spacing of the position in the second direction matches the first preset spacing; when it matches, obtain the position information of multiple second preset positions on the box; detect the distance between the first preset position and the second preset position Whether the pitch matches the second preset pitch; when matched, assemble the cabinet and a plurality of display modules. According to the position information of the first preset position of the display module and the first preset distance, adjust the distance between adjacent and even display modules, thereby improving the gap accuracy between the display modules; according to the second preset Set the position information of the position and the second preset distance, adjust the distance between the parallel cabinet and the display module, so that the distance between the cabinet and the display module can be adjusted, thereby improving the distance between the display module and the cabinet flatness.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a display screen and an assembly method thereof. Background technique [0002] With the improvement of the production technology of LED (Light-Emitting-Diode) display, since the LED display is composed of multiple display modules, there is a gap between adjacent display modules, which will make adjacent display modules The pixel spacing between modules is too large or too small, that is, the pixel spacing between two adjacent modules exceeds the range of the preset spacing, which affects the overall display effect of the display screen. For example, when two adjacent modules When the pixel pitch between two adjacent modules is too large, there will be a lack of pixels in the preset gap between two adjacent modules, thus forming a dark line; There are too many pixels in the preset gap to form bright lines, and the difference in thickness between two adjacent modules also ...

AI Technical Summary

Problems solved by technology

[0003] For small-pitch display screens, as the pixel pitch decreases, the processing accuracy requirements for the cabinet and bottom case become more and more stringent, while traditional assembly methods include manual assembly, robotic assembly, or positioning by scanning systems Afterwards, manual / mechanical assembly is carried out. On the basis of the precision box, bottom case and module, the cumulative error of the box-bottom case, bottom case-module is still too large, and the module installation process still needs to be repeated. Replace the position of the module, and then manually adjust it in a small range, the adjustability is poor, and the improvement effect is not obvious, which makes the gap accuracy between the module and the module and the flatness of the cabinet lower, and the small-pitch display screen The display effect is poor
