Combining high performance and power efficiency in a standard-size module, Sharp Microelectronics of the Americas has introduced a new 4.3-inch amorphous silicon thin-film transistor liquid crystal display (TFT-LCD) for next-generation mobile devices. The LQ043T3DX02 digital landscape display features a 16:9 aspect ratio, 480 x 272 pixel format, and is capable of displaying 16 million colors.

The new displays target new and emerging mobile products in North America with audio/visual capabilities such as gaming devices, portable media players and DVD players that demand a significantly wider range of colors, higher brightness, high contrast, and low-power consumption in a landscape orientation. The new display can also be used for PDAs, GPS devices, instrumentation and portable medical equipment that require greater on-screen performance.

"Feature-rich mobile devices must be capable of displaying images in either portrait or landscape mode to accommodate the various uses of an application. Because of this, there is a growing need among portable product designers to incorporate high-quality displays with wide viewing cones and 16:9 aspect ratio into products," said Dave Hagan, product marketing manager for the Display Business Unit at Sharp Microelectronics of the Americas, in a statement.

In the past, the company said OEMs developing mobile A/V products were limited to portrait mode displays which taxed the ARM microprocessor or DSP to rotate the images into a landscape orientation. The symmetrical viewing cone of the new display gives engineers the option of using the display in either landscape or portrait mode. It comes with a standard TFT interface, and because it is backlit by seven LEDs, the color screen can be continuously dimmed to save additional power for other functions.

Developed with proprietary Advanced Super View (ASV) technology, the display features a 160(H) x 160 (V) viewing cone, so images can be viewed from any angle without color reversal. Also thanks to the ASV technology, the display features a low-reflective black screen that yields higher contrast, good black level uniformity, and a high image quality. It also allows users to view graphics, video and still images in a wide range of ambient lighting conditions.

Other specifications include a pixel pitch of 0.198(H)-by-0.198(V)mm, active area of 95.04(H)-by-53.856(V)mm, outline dimension of 105.5(W)-by-67.2(H)-by-3.95(D)mm, brightness of 165cd/m? (7 LED, 18mA), NTSC ratio of 48 percent, and contrast ratio of 400:1.

The display integrates with Sharp's line of BlueStreak microcontrollers and SoC, as well as the company's full system solutions that include Flash memory, imagers and optoelectronics.

The LQ043T3DX02 will be in production starting in June 2005. One-piece price is $116.
