Definitions
- the present disclosure relates to the field of display technologies, and in particular, to a display substrate, a method for fabricating the same, and a display device.
- a negative air pressure is applied to the through hole from the back surface of the printing template to cause the LED particles to be adsorbed in the fitting groove.
- the LED particles on each of the printing templates are respectively transferred onto the same substrate to form an array of LED particles on the substrate that is consistent with the arrangement of the sub-pixels.
- FIG. 4 is a schematic view showing the structure of an array of LED particles in the display substrate shown in FIG. 2.
- the red LED particles LR, the green LED particles LG, and the blue LED particles LB are alternately arranged in an array, wherein the red LED particles LR, the green LED particles LG, and the blue are arranged in the same row.
- the order of the LED fine particles LB is sequentially arranged, and the same column is sequentially arranged in the order of the red LED fine particles LR, the blue LED fine particles LB, and the green LED fine particles LG. Comparing Fig. 2 and Fig. 4, it can be seen that the arrangement of the LED particles is consistent with the arrangement of the sub-pixels in the display substrate, which is mainly by the arrangement of the grooves on the printing template and the printing template during the transfer process. Realized by the alignment of the base substrate.
