The thickness of only 25mm OMRON LED backlight Tama!

Japan's OMRON and FINE Tama OPTO exhibited only 25mm thickness of direct type LED backlight. The backlight is an improved version of the FLATLED (red), G (green), B (blue) LED package as a light source component in a grid configuration with more than one R configuration. It is characterized by a variety of colors within the various components of the LED light generated a certain degree of color mixing, so you can shorten the distance of the LCD panel. In the "FPD International 2004" exhibited thick 30mm backlight, has attracted wide attention. This is another feature of backlight is easy to achieve local control back according to local control light state "(Area Control)". 32 inch LED backlight, we can see that the configuration of a plurality of light source element is on display 32 inch back illuminated light, brightness is 11000cd/m2, power consumption is 150W. Color range of NTSC is more than 100%. About 300 x 22mm x 22mm x 6mm light source components. Each light source element has 5 LED, in which the red LED is 1, green LED and blue LED each of the 2. The was able to achieve a slim, because of the further spread of the light emitted by the light source element. As a result, "even if the liquid crystal panel and the backlight is closer to the point, it is not easy to see each grid configuration of the light source component of the light spot" (OMRON commentator). It is reported that, in order to make the light diffusion, in the upper part of the LED to install the diffusion resin, and the element has a mirror into a white resin, further improve the degree of light diffusion. By making the light source element diffusion of light, backlight bright spots and pigmentation also reached a practical level "(OMRON Guide), such as bright spot, in the plane of the brightest and darkest parts of the brightness difference control in less than 10%. OMRON and FINE Tama OPTO said, will consider the sample delivery 25mm back light.
