Embodiment Construction

[0023] The given embodiment of the present invention can refer to accompanying drawing:

[0024] First, the light guide plate is prefabricated: the light guide plate 5 can be a single material of organic PmmA or PC, or the substrate is PmmA, the surface is PC or coated with a thin layer of silicone wear-resistant, and the surface of inorganic optical thin glass and organic substrate can also be composited. made. The concave holes 7 on the top of the cylindrical lens are prefabricated on both sides, and the light-emitting diodes are pre-embedded in it, and epoxy-type optical resin glue is injected. If the LED light-emitting tube is arranged on one side, a layer of reflective film can be pasted on the opposite side. On the front of the light guide plate, a rough scattering layer 4 is injected through a film, and the rough scattering layer 4 can form a prismatic concave-convex shape by interlacing dotted lines.

[0025] Secondly, the fixed frame 8 is made into a set of grooves ...

Abstract

An integrated type LED otpical display assembled with components includes light guide sheet and fixed frame, of which the light guide sheet having several shapes corresponding to fixed groove of the fixed rack is fixed in the middle of the groove in interval and it has prebuilt LED lighting tubes at one side or both sides of its periphery. The light guide sheet has rough light dispersing layer covered with the window covering plate which can display pictures and signs or covered with the light reflecting film on its positive face. The present display has a transparent protecting layer at its outermost layer and a back cover plate at its back side. The display has the advantages of high and uniform brightness, good light electric performance, suitable for large scale production in batch type and individualized assembling.

Description

technical field [0001] The invention relates to 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, red and other LED materials at home and abroad, and are 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, external packaging is usually used to change the light intensity distribution, such as lens packaging, and matrix flat display modules made of plastic injection molding frames. The display icons of the above-mentioned display module basically correspond to the working points of the LED chip. It is difficult to change from a point light source to a surface light source, which affects the development of LEDs to...
