Embodiment 1
[0049] see figure 1 , figure 1 A schematic structural diagram of a virtual LED display module based on a three-color strip LED chip provided by an embodiment of the present invention.
[0050] The virtual LED display module 10 includes a three-color LED chipset 11, which is composed of several three-color strip LED chips; each three-color strip LED chip includes three LED light-emitting units R, G, and B; There are three types of color bar-shaped LED chips, including a first three-color bar-shaped LED chip 12 , a second three-color bar-shaped LED chip 13 and a third three-color bar-shaped LED chip 14 . Wherein, the 3 LED light-emitting units of the first three-color strip LED chip 12 are arranged in RGB order; the three LED light-emitting units of the second three-color strip LED chip are arranged in BRG order; the third three-color strip The three LED light-emitting units of the LED chip are arranged sequentially in GBR. The plurality of three-color strip-shaped LED chips ...
Embodiment 2
[0064] The three-color bar-shaped LED chip of the embodiment of the present invention is an RGB three-color integrated LED chip prepared based on GaN materials and using three colors of light-emitting materials. The three-color bar-shaped LED chip structurally includes light-emitting units of three primary colors, which are red LED light-emitting units, green LED light-emitting units, and blue LED light-emitting units, and also includes N-type electrodes and P-type electrodes. The surroundings of the three primary color light-emitting units are filled with isolation substances, forming an isolation layer between two adjacent LED light-emitting units.
