Embodiment

[0025] Referring to Figures 1-2 As shown in the figure, a kind of hexagonal three primary color LED includes hexagonal package piece main body, and package piece main body is provided with red LED (R), green LED (G) and blue LED (B) these three different color LEDs in it.The anode of the above-mentioned red LED, green LED and blue LED is in the center position of package piece main body, to form anode in this center position.This common electrode design mode is conducive to the connection of circuit and the transmission of signal, simplifies the complexity of circuit structure.

[0026] The red LED, the green LED and the blue LED are arranged in a ring array with the center of the package body as a reference.

[0027] On this basis, the red LED, the green LED and the blue LED form a red display unit, a green display unit and a blue display unit on the package body.

[0028] The design of the hexagonal three-primary color LED has obvious advantages. From the perspective of optics, various colors can be mixed by combining red, green and blue, meeting different color display requirements and having great potential in color brightness and accuracy. From the perspective of electricity and structure, the specific distribution of the positive and negative electrodes on the back is conducive to the optimization of the internal circuit and the improvement of the stability and reliability of the LED. Meanwhile, the hexagonal shape of the package body provides unique spatial adaptability in different application scenarios.

[0029] In combination with Figures 3-5 As shown in the figure, a Micro LED display screen has a TFT circuit layer 1, an LED layer 2 and a protective layer 3 from bottom to top.

[0030] The TFT circuit layer 1 mainly undertakes the function of signal transmission, which can accurately transmit signals to each LED in the LED layer 2, ensuring accurate lighting and color display of each LED. The LED layer 2 as the core light-emitting layer uses the hexagonal three-primary color LED to realize colorful color display by combining red, green and blue, providing the basis for the display screen. The protective layer 3 protects the internal structure from physical damage, water vapor erosion and other damages to the TFT circuit layer 1 and the LED layer 2, prolonging the service life of the display screen and ensuring its performance stability.

[0031] In this embodiment, the plurality of hexagonal three-primary color LEDs on the LED layer 2 have a plurality of arrangement modes. They can be arranged in a rectangular array, which is relatively regular and facilitates orderly transmission and control of signals; or they can be arranged in a "honeycomb" structure, which enables more efficient and closer connection between the LEDs. Of course, the arrangement modes of the hexagonal three-primary color LEDs on the LED layer 2 include but are not limited to the two modes, and different arrangement modes can meet different display requirements and performance requirements.

[0032] The Micro LED display screen of the utility model innovates in the pixel arrangement mode, and changes the original pixel arrangement mode to three-primary color LED arrangement. By integrating red, green and blue three-color LEDs in the packaging body of each LED, the packaging body is then used as a whole for massive transfer. Compared with the traditional Micro LED display screen which needs to realize rich color display through RGB color mixing, the efficiency of Micro LED massive transfer is greatly improved. Moreover, the error probability caused by multiple operations is reduced, thereby improving the yield. At the same time, the simplification of the process and the improvement of the yield also reduce the production cost.
