embedded world: Sharp microelectronics to set new standards in light technology?

Designed for total or partial outside use, the high brightness models feature 19 and 23in diagonal screens, led backlighting and operate at a temperature range between -20 and 60°C. According to Sharp, the LQ190E1LX51 and LQ231U1LW31 devices offer a brightness of up to 1000 and 500cd/m² respectively, as well as a service life of up to 50,000 hours. In addition, the new 15 and 25W Mega Zeni models are designed to be compact, lightweight and according to Sharp, offer 'exceptional' brightness. The company says the devices can produce a light output of up to 2550 lumen (depending on the model) and will set 'new standards' for light technology. Measuring 24 x 20 x 1.8mm and with an aluminium ceramic plate as the carrier material, the devices are optimised to deliver a luminous flux of up to 102lm/W at an operating temperature of 80°C. Expanding its range of memory lcds, Sharp has also introduced a 2.7in (LS027B4DH01) display with a resolution of 400 x 240, a 2.94in (LS029B4DN01) model with a resolution of 456 x 240 pixels and a 6.02in model (LS060S2UD01) with a resolution of 600 x 800 pixels to specifically address the e-books market and other portable reading devices. For this particular market segment, Sharp aims to supplement the range with transflective and touchscreen models in the first half of 2011. Lastly, the company announced new HAP modules, designed to provide simple solutions for the uncomplicated design-in of displays such as human machine interfaces (HMIs) for appliances such as coffee machines, microwave ovens and washing machines. The devices are designed for use at operating temperatures ranging from -10 to 60°C.
