The Institute published ultra-thin soft RGB-LED light display technology, expect to find new export products for LED Taiwan factory

Taiwan city is an important industrial technology research institute (ITRI), assembly and material of the polymer group announced in the day before what's the lightning 2 group research team jointly issued a ultra-thin soft direct type light source module prototype, first display can be bent and image display of the seven "concept product.

This module combines the advantages of direct light and side light type LED LED type light source, the design of ultra-thin prototype products, can provide local dimming capability, Dimming_ and Local (multi block full-color control so that the screen can be displayed on the digital and simple drawings. In particular, when the LED display module is bent, the brightness and chroma of each angle are not affected.

The Institute pointed out that the module uses a combination of LED chip on zero gap flexible substrate technology and the development of new light diffusion film group two novel technology, ultra-thin package LED chip on soft substrate does not need to display lamp lighting source thickness is less than 1mm, can carry out precise control of any single point of light and color response time; zero clearance light diffusion film group can directly contact with the light emitting point LED (Contact), through the structure of the multilayer LED point light source with high efficiency diffusion halo, showing homogeneous light emitting area, thickness is less than 1.5mm, the combination of the thickness of only 2.5mm.

A map of the main technical differences, the general source requires a longer diffusion distance is in the bottom of the light source module, also produced a light source module and thickness control problem of thick, this technique uses special diffusion film for direct contact light source, no air gap layer is larger, therefore in the assembly with the deflection, are of great advantage.

A table for the display of machine specifications finishing, full-color brightness above 2000nits, as the indoor and outdoor signs, instructions, advertising and display that can be attached to the light source module, any vehicle, such as window glass, plastic board, table plate, wall or poles, cement column bending surface. Easy and convenient use, can be used as white light source local area (Fig. three). Ultrathin thickness (Figure four) less than 2.5mm.

Full color pattern technology (Figure five) by static or dynamic performance such as film (Figure six) is shown by the color sequence of the way, at the same time display color and pattern required in a surface or plane, and the power required for the total power consumption of only 1/3-1/2, the cost of less than 50 dollars, can use proportional amplifier or elastic splicing way to get larger display area, application development is very suitable for domestic LED manufacturer of multimedia products.
