Sharp Microelectronics of the Americas announced its 2.2-inch QCIF+ Advanced-TFT LCD (AD-TFT LCD) module to meet the needs of design engineers in North America developing new and emerging mobile devices capable of showing text, video content and still images. Sharp is the first company to offer this size display as a standard part for both mobile phone and other portable handheld applications.
As mobile phone users upgrade to new, multi-feature models, and as new categories of A/V products emerge, such as portable media players, there is a growing demand for small, high-resolution color display modules capable of showing text, still photos and video. These displays must meet stringent display requirements and do so at price points necessary to attract consumers at every level of entry. Sharp's new, cost-effective 2.2-inch QCIF+ AD-TFT LCD offers the best combination of display technology and power efficiency available for these low-cost mobile products.
The 2.2-inch QCIF+ AD-TFT module is thin, rugged, lightweight, features low power consumption, fast response rate and supports full-motion color. Developed using Advanced-TFT (Transflective) display technology, images are readable in a full range of ambient lighting conditions both inside and outdoors. This is accomplished because the transflective mode is optimized with an emphasis on reflectivity, and the panel more closely resembles the characteristics of paper than other LCDs. To reduce power consumption, this display module is backlit using white LEDs and can be used in different modes to reduce color, reduce refresh rate, or to write to only part of the screen.
Sharp Reference Designs for Portable Media Players
Sharp's 2.2-inch QCIF+ AD-TFT is one of the key components to a reference design recently announced by Sharp for lower-cost portable media players (PMP), an emerging category of portable handheld devices that can play audio, slide shows and video content on a single application. A reference design using a 3.6-inch QVGA landscape display for mid-range PMPs was also announced. The reference designs provide complete hardware and software solutions to speed time to market and lower system costs, and also feature the Sharp BlueStreak(tm) LH7A404 ARM9 System-on-Chip as the interface for the display.
