High-Brightness TFT LCDs Go Industrial

High-brightness TFT LCDs go industrial Three new 15-in. active-matrix thin-film-transistor (TFT) LCD modules flaunt the high brightness needed for industrial applications like wide-angle factory automation, test and measurement, kiosk, and financial point-of-sale. Developed by Toshiba, the XGA modules (1024 by 768 pixels) also fit financial and medical products as well as a host of emerging applications requiring superior image quality.

These LCDs come with four lamps, instead of the typical two, for higher brightness levels that range from 350 to 400 candelas/meter2 (cd/m2). Featured are wide viewing angles of 160° horizontal and 140° vertical, along with a high contrast level and a fast response time of 25 ms.

The LTM15C458C suits cost-constrained applications that require high brightness levels. The LTM15C458S offers the highest luminance rating at 400 cd/m2. The LTM15C458T fits applications where mounting is above eye level, such as airport arrival/departure screens.

The LCDs offer a high color range of 72% of the NTSC TV spec, which is significantly more than the typical 40% to 50% on the market. Long-life, cold-cathode fluorescent lamp (CCFL) backlighting with four replaceable lamps is an added feature.

Pricing for the LTM15C458C, LTM15C458S, and LTM15C458T is $385, $400, and $415 each, respectively, in sample quantities.
