Embodiment Construction

[0020] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0021] refer to figure 1 , a low-brightness, high-gray, high-display LED manufacturing process provided by the present invention comprises steps:

[0022] S1. Add black raw materials when making the substrate, so that the substrate becomes a black matrix carrier;

[0023] S2, install the chip and the crystal wire on the black substrate, and carry out crystal bonding and welding respectively;

[0024] S3, making black colloid, and encapsulating the black colloid on the LED;

[0025] S4, baking and splitting the LED;

[0026] S5. Packaging and sealing the LED after packaging.

[0027] Compared with the prior art, the low-brightness, high-gray and high-display LED manufacturing process provided by the present invention adopts an all-black manufacturing design, so that the front side of the LED light is completely...

Abstract

The invention discloses a low-brightness high-gray high-display LED manufacturing process which comprises the steps of S1, adding a black raw material in manufacturing a substrate so that the substrate becomes a black matrix carrier; S2, mounting a wafer and a crystal wire on the black substrate, and performing crystal fixing and welding; S3, manufacturing black colloid, and packaging the black colloid on the LED; S4, performing baking and optical splicing on the LED; and S5, performing package sealing on the packaged LED. Through a total-black manufacturing design, light emitting from the front surface of the LED is black totally. The light source of the LED emits light from a relatively black background, thereby realizing higher contrast effect, better visual effect and high contrast in the picture of a display screen when the LED is applied in the display screen.

Description

technical field [0001] The invention relates to the technical field of a logarithmic eye chart, in particular to an LED manufacturing process with low brightness, high gray and high display. Background technique [0002] Light Emitting Diode (LED) is a semiconductor electronic component capable of emitting light, which can convert electrical energy into light energy output. Because of its high brightness and illuminance and low power consumption, it is widely used in lighting, display and other fields. However, the light-emitting surface of the currently used LED display is point-emitting and a light surface, which is prone to glare and reflection, and the display contrast is not high. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention provides a simple and convenient LED manufacturing process with low brightness, high gray and high display. [0004] In order to achieve the above purpose, the present i...
