Sharp has unveiled five industrial-standard, 7inch TFT LCDs. The spectrum ranges from the robust screens of the mechanically resilient Strong2 class, with extended temperature range from -30 to +80°C, to a light type, the LQ070Y3DG3A with an operating temperature of -20 to +50°C, which is designed to be more suitable for consumer applications. Type LQ070Y3DG3B is a touch screen model that has good optical properties. With 300cd/m², it possesses comparatively high brightness and is every bit equal in terms of contrast to its non touch screen sister model. This display is also slim, at 7.1mm being only 1.1mm deeper than the LQ070Y3DG3A, which does not have the touch screen unit. All the new displays have LED-based backlight. With a depth, depending on model, of between only 6 and 9mm, the new displays have less than half the depth of comparable CCFL variants. This is accompanied by high mechanical robustness, LEDs being far less fragile compared with the glass bodies of cold cathode tubes. The company has developed a special chassis for LED backlit industrial displays in which the backlighting LEDs are linked thermally directly with the mechanical parts of the module.
