Embodiment Construction

[0017] Such as figure 1 As shown, in a specific embodiment, the encapsulation lens 6 of the LED point light source inherits four LED monochrome chips whose primary colors are red 1, green 2, blue 3 and white 4 respectively, and the four LED monochrome chips are misplaced and overlapped. And share one anode pin 5. Pin 1-1, pin 2-1, pin 3-1 and pin 4-1 are the cathodes of four single-color chips of red 1, green 2, blue 3 and white 4 respectively. Five pins lead out the encapsulation lens 6 from the semi-major axis of the ellipse on the bottom surface of the encapsulation lens, forming a "four cores and five pins" structure.

[0018] Such as figure 2 As shown, the cross-sectional shape of the packaged lens 6 is elliptical, and the five pins are evenly distributed on the semi-major axis.

Abstract

The invention belongs to the light-emitting diode (LED) technical field, in particular to a novel chip which can is suitable for being used as display pixels. Due to the fact that a geometric structure with an oval sectional area is adopted by a packaging lens, the LED light source disclosed by the invention is characterized in that in display screen applications, the horizontal raster is wide and the requirements of display screen applications are met. Due to the fact that an 'all-in-one' chip structure is adopted by the LED full-color display screen, the LED display screen disclosed by the invention is enabled to have the advantages that the pixel display is accurate, the video colors are realistic.

Description

technical field [0001] The invention belongs to the field of LED technology, and more specifically relates to an LED point light source capable of improving the display effect of an LED display screen and a manufacturing method thereof. Background technique [0002] In many applications of LEDs, LED light sources are required to have a wider light domain in a certain dimension. For example, in display technology, a wider light domain is required in the horizontal direction so that viewers in different directions can see continuous And a consistent image, at the same time, the light field requirements in the vertical direction are not very high. [0003] On the other hand, since LEDs are angled, LED displays also have angular directionality. That is, when viewed from different angles, its brightness will gradually increase or decrease. The angular consistency of the three primary colors of red, green and blue LEDs will directly affect the fidelity of video colors. [0004]...
