Embodiment Construction

[0022] The innovations and protection scope of the present invention will be described in detail in conjunction with the accompanying drawings. The red chips, green chips, blue chips and white chips in the description specifically mean that the primary colors of the LED chips are red, green, blue and white, respectively, that is, the luminous colors are red, green, blue and white, respectively.

[0023] figure 1 It is a composite chip including one red chip and one green chip. The negative poles of the red chip 1 and the green chip 2 are fused together to form a common negative pole 4, and the positive poles 5 and 6 of the red chip 1 and the green chip 2 are isolated from each other. The two chips are packaged together in a wafer housing 3 with two cores and three pins.

[0024] figure 2 It is a composite chip including one red chip 1, one green chip 2 and one blue chip 3. The positive poles of the three chips are laser welded together to form a common positive pole 5, and ...

Abstract

The invention discloses an LED (light-emitting diode) composite chip, a processing method, and a display screen using the composite chip, and belongs to the technical field of LEDs. The invention particularly discloses a composite chip comprising a plurality of LED monochrome chips. The processing efficiency of the LED display screen display accuracy of pixels can be improved, and the manufacturing cost can be lowered. In addition, the composite chip can also be applied to certain specific locations, such as the outer space, the military and the like; the life of an LED light source is prolonged; the reliability of the LED light source is improved; and the composite chip has an obvious improvement.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of LED technology. 【Background technique】 [0003] LED display has gradually won the recognition of customers due to its long life, bright colors, wide viewing angle, easy modularization of structure, and simple grid connection method. The scope of application has gradually penetrated from traditional lighting instructions to decoration, display, aviation , Submarine operations and other civil and industrial fields. [0004] Commercially available LED displays can be divided into single-color, double-color and three-color according to the color, and the three-color display is divided into full-color and true-color. The production principle of the two-color display is to use two single-color LED lights as a pixel, and the production principle of the three-color display is to use three single-color LED lights as a pixel. By adjusting the color of each pixel, A different pattern or text is displayed. [00...
