Abstract

The present invention is one plate display with LED as light source and its preparation. The plate display includes light guide plate with one group of cylindrical lens cavities around it and LEDs inside the cavities. The surface of the light guide plate has a rough light-dispersing surface layer with display signs and one covering layer of luminous paint. The said device has the advantages of high light transparency clear display, homogeneous lighting, etc. The present invention may be used in producing various monochromic and color LED display.

Description

Technical field [0001] The invention relates to a method for preparing a flat panel display device using a light-emitting diode as a light source. Background technique [0002] In recent years, there have been major breakthroughs and rapid development of ultra-high-brightness green, blue, and red LED materials at home and abroad, and they have been called new optoelectronic light sources by domestic and foreign experts. Single crystal LED light-emitting chip is usually 0.2×0.2-0.3×0.3mm 2 , Is a very small point light source. In order to give full play to the performance characteristics of LEDs, shape packaging is usually used to change the light intensity distribution, such as lens packaging, and a matrix flat display module made of a plastic injection frame. The display icons of the above-mentioned display module and the working point of the LED chip basically correspond to each other, and it is difficult to change from a point light source to a surface light source, which affe...
