3,5-inch TFT-LCD

28 June 2006 Opto-Electronics

Touting outstanding price/performance value, Sharp Microelectronics' 3,5-inch QVGA thin-film transistor liquid crystal display (TFT-LCD) with integrated touch screen, the LQ035Q7DH06, is a higher performance upgrade of its LQ035Q7DH01, offering 225 nits of brightness from six high-efficiency white LED backlights and 4% reflectivity.

Power consumption is 405 mW with the backlight (21 mW without backlight). The display also offers readability in a wide range of ambient environments. The QVGA mobile display includes a high bright panel with transflective properties and 262 144 colours. The contrast ratio is 80:1 in transmissive mode and 3:1 in reflective mode. This display panel only requires a Sharp-supplied ASIC timing control chip. Both the LQ035Q7DH06 display and LZ9FC23 controller are RoHS-compliant.

The display also features an integrated touch panel that simplifies the design process by allowing design engineers to include a user interface, says the company, lending itself to a greater range of handheld product applications including portable media players, handheld gaming devices and portable DVD players. It can also be used in applications that call for greater on-screen performance such as PDAs, GPS/navigation devices, test and measurement instruments and portable patient monitoring equipment.
