Full-color flexible RGB faceplate and manufacturing method thereof

Abstract

The invention discloses a full-color flexible RGB faceplate. The full-color flexible RGB faceplate comprises a luminescent material layer, an electronic transmitting layer positioned on the luminescent material layer and an LED luminescent layer on the electronic transmitting layer. The LED luminescent layer uses a Flip chip blue chip (6). Green fluorescent powder and red fluorescent powder are sprayed on the surface of the Flip chip blue chip (6). The LED luminescent layer is provided with cover plate glass. The Flip chip blue chip (6) is used, and the green fluorescent powder and red fluorescent powder are sprayed on the surface of the Flip chip blue chip (6), so the corresponding green and red are emitted by the Flip chip blue chip (6). The current blue chip is matched with the Flip chip blue chip (6), so the full-color effect is achieved.

Description

technical field [0001] The invention relates to the technical field of LED light sources, in particular to a full-color flexible RGB panel and a manufacturing method thereof. Background technique [0002] Except for the blue chip, Flip chip chip has few red and green chips. If you use a front-mounted chip, you need to wire it. The reliability of the wire bonding on the flexible panel is very poor. It is relatively limited to realize the light color of other colors on the flexible substrate. , the existing flexible finished products are basically the white light emitted by the Flip chip blue chip plus yellow phosphor excitation, and there is no full-color RGB light color. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide a full-color flexible RGB panel and its manufacturing method, using a Flip chip blue chip, spraying green phosphor and red phosphor on its surface, so that it emits co...
