Title: DISPLAY SUBSTRATE AND PRODUCTION METHOD THEREOF, AND DISPLAY DEVICE
Abstract:
Provided are a display substrate and production method thereof, and a display device. The production method of the display substrate comprises: assembling LED chips of each color category (LR, LG, and LB) in printed templates (MR, MG, and MB) corresponding to each color category; arranging mounting grooves (F1, F2, and F3) on the printed template surfaces (MR, MG, and MB) on the basis of sub-pixel arrangements (PR, PG, and PB) corresponding to each color category; and separately transferring the LED chips (LR, LG, and LB) on each printed template (MR, MG, and MB) to a same substrate, so as to form on the substrate an LED chip array consistent with the sub-pixel arrangement. On the basis of the method, a production process of a color LED display device can be simplified. Compared with the prior art, the method of the invention can reduce production process complexity of a color LED display device, and lower costs.
