Problems solved by technology

With such a structure, there are several points for improvement: 1. In order to obtain a current that emits light within a certain range, a resistor needs to be added in the structure to adjust the current; For the metal layer to input current to emit light, it is necessary to combine the bare LED die with the metal pad on the soft board by wire bonding; 3. When the bare LED die is fixed on the metal backing board, Put soft glue on it to protect its structure; 4. The second metal layer has a high astigmatism rate, which will make the light of the bare die of the light-emitting diode in the dot matrix layout state, and the light will be hazy.

Abstract

The invention relates to an ultra-thin light-emitting diode (LED) display. The display not only can be applied to single LED, but also can be applied to seven-segment displays, LED bars, dot matrix phalanxes and other special displays with specific patterns and design.

Description

technical field [0001] The present invention relates to an ultra-thin light-emitting diode display. The display of the present invention can be applied not only to a single light-emitting diode, but also to seven-segment displays, light-emitting diode display bars (Bar), dot matrix squares, and other specific Dedicated display for patterns and designs. Background technique [0002] This type of light-emitting diode display is currently known, such as the "flexible LED surface light source structure, flexible board, and manufacturing method thereof" announced by the patent bulletin I289947 (application 095109119) in Taiwan, such as figure 2 shown. The flexible LED surface light source structure includes: a flexible board with a first metal layer and a second metal layer, the first metal layer has a circuit layout, and the second metal layer is in a circular structure or fully Formed on the flexible board, and the second metal layer has a metal coating with high reflectivity...
