Sharp signage displays integrate LED drivers

New Products |
By eeNews Europe

The displays are designed for the requirements of digital signage applications and therefore offer a lifespan, depending on the model, of up to 60,000 hours of 24/7 continuous operation and, for the most part, an extended range of operating temperatures from 0° to 50°C. The most state-of-the-art technology from the development of TV ensures the brilliant image resolution. This includes Sharp’s proprietary UV2A process (which guarantees a wide viewing angle and high contrast conditions), Full HD with 1920 x 1080 pixels as standard resolution, Quattron technology for some models with yellow as an additional subpixel, and LED-based background lighting for all displays. Through local dimming, it not only allows the targeted increase of contrast to 1 million to 1 but rather it is also the basis for the screen’s high energy efficiency. For many models of the series, the drivers for LED backlighting and pulse-width modulation dimming are already integrated.

The new e-Signage model series includes standard TFT LCD modules of the types LK600D3LBX, LK695D3LBX, and LK800D3LBX in brightness levels of 350 cd/m², 500 cd/m² and 700 cd/m². In addition, Sharp offers numerous special models:

Suited especially for outside e-Signage applications are the 60 and 70 inch high-brightness models LK600D3LB14, LD600D3LH1, and LD700D3LH1, which, thanks to their brightness of up to 2,000 cd/m² are easy to read even in bright daylight. The integrated dimming capability makes it simple to adjust the display to lower levels of ambient light, which keep the average energy consumption within limits, despite the high backlight performance,

For applications that require an especially high resolution, like the imaging methods of medical diagnostics or special monitors in the movie and advertising industry, Sharp has Ultra High Resolution LCD panels available that, with 3840 x 2160 pixels, have more than four times the resolution of Full HD. Currently, the portfolio includes two models (types LK601R3LA19, LQ315D1LG91) with 60 and 31.5 inch screens; a 70 inch variant and an improved 60 inch variant are being planned for the second half of the year.

With two super narrow bezel TFT LCDs with a brightness of 1,500 cd/m² and 700 cd/m² and 60 inch diagonal screens, Sharp also offers displays that are especially suited to design monitors for the construction of video walls. Because of their special chassis, the modules have an asymmetrical frame with a thickness of only 2.4 mm and 4.1 mm, each on two sides, which leads to a total ligament width of 6.5 mm. This allows for the modular construction of almost seamless large-scale displays in any desired size.

Series production for the new signage displays is scheduled to start in the first quarter of 2012.
