LCDs for handheld designs

20 February 2008 Opto-Electronics

The new LS022Q8UX05 2,2-inch TFT LCD and LQ025Q3DW02 2,5-inch display from Sharp Microelectronics are primarily aimed at the rapidly growing market for special handhelds. These include small-format industrial portables eg, testing and measuring devices and mobile systems for medical applications, as well as different consumer electronics products such as media players, cordless fixed network telephones and remote control handsets.

Thanks to their standard interfaces - 8 bit CPU for the LS022Q8UX05 and CMOS for the LQ025Q3DW02 - both LCDs can be integrated into many different applications and are simple to control. The QVGA resolution and a contrast ratio of 400:1 with a brightness of up to 350 cd/m² give brilliant picture reproduction. The displays are also equipped with Sharp's proprietary ASV technology, which provides a 160° viewing angle in all directions.

The 2,2-inch LCD is also a transflective display; in other words, around 4% of the structures within the display are coated with reflective microstructures that generate a contrast of 10:1 in reflective mode. This means that the display guarantees high visibility at all ambient light conditions, even in direct sunlight. With Sharp's Continuous Grain Silicon technology, the necessary drivers and power ICs for controlling the LS022Q8UX05 are directly integrated into the display glass.
