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 the color 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 invention also relates to a packaging method of the above-mentioned display screen. Background technique [0002] The light-emitting diode display is a new type of information display medium that has 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 flat panel display field and have been widely used. [0003] The application range of LED displays involves many social and economic fields, such as financial information display of stock exchanges and banks; airport flight dynamic information display; passenger guidance information display such as ports, stations, and passenger trains; road traffic information display; sports venues , Command center, shopping mall and other large places information display. There...
