Challenges LED projection OLED micro projection technology appears

Recently, the German Institute of Applied Optics and precision engineering, named Fraunhofer, demonstrated a new OLED technology using a micro projector.

It does not use the general micro projectors are used DLP or LCOS technology, but the use of OLED technology, and the biggest advantage of this technology is the need for static optical systems, such as lens. Since OLED is self luminous, there is no need for DLP to use the reflected light projection technique.

This projector uses a 8 x 6mm green OLED panel, can be projected out of 640 x 480 screen. In terms of size, the diameter is only 17mm, the length is only 24mm, and the entire volume of only 10 cubic centimeters. In terms of performance, the current projector can be projected on the 30-50cm distance of 6 inches of the size of the screen, but it is now faced with the same problem as the LED projector - brightness is too low.

However, according to the inventor said that the current OLED technology is still in development, if the future brightness can reach 4-5 times now, then this technology will be maximized application.

Commentary: active lighting technology prospects, the main problem is the brightness and cost control.
