LED display screen and encapsulation method thereof

Abstract

The invention discloses a light emitting diode display screen, wherein a light emitting diode naked chipset is stuck on the front surface of a printing circuit board, and the outer side of the light emitting diode naked chipset is equipped with an integrated encapsulated sticking membrane. The invention further discloses an encapsulated method of the light emitting diode display screen. Because the light emitting diode display screen uses a special device to do a patch treatment of the light emitting diode naked chipset, simultaneously, the encapsulated sticking membrane is an integrated body,the leveling of the light emitting diode display screen which is obtained by the method is observably improved, a wave phenomenon can be avoided to produce when words or images are displayed, and thecolor of the display screen also can have a higher consistency.

Description

technical field [0001] The invention relates to a display screen, in particular to a display screen using a semiconductor light-emitting diode (LED) as a luminous body. The present invention also relates to a packaging method for the above-mentioned display screen. Background technique [0002] Light-emitting diode display is a new type of information display media that developed rapidly around the world in the late 1980s. In less than two decades, light-emitting diodes have rapidly grown into mainstream products in the field of flat panel displays and have been widely used. [0003] The application range of light-emitting diode displays involves many fields of social economy, such as the financial information display of stock exchanges and banks; the dynamic information display of airport flights; the display of passenger guidance information such as ports, stations, and passenger trains; the display of road traffic information; sports venues , command center, shopping ce...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned hardware mode mainly has the following disadvantages: since the existing light-emitting diode display screen is assembled from a plurality of digital dot matrix modules, it takes a lot of energy and time to debug the consistency of brightness and color of each dot matrix module; In the process of assembling multiple dot matrix modules on the circuit board, unevenness will inevitably appear on the surface of the display screen, and the flatness of the entire display screen is also poor, which affects its appearance

In addition, because the light-emitting hole is deep, the light-emitting diode is in a relatively deep position, so the included angle of the scattered light is small, and the viewing angle of the display screen is small.
