The Sharp LQ057Q3DC17 is a 5.7-inch a-Si TFT-LCD module designed for space-constrained embedded and industrial applications that demand reliable performance and consistent image quality. Featuring a QVGA resolution of 320 × 240 pixels, this display is tailored for compact systems where clarity and form factor are equally important. Its active area of 115.2 mm × 86.4 mm mirrors the overall form factor, simplifying mechanical integration and enabling efficient use of panel real estate.
The display offers a typical luminance of 500 cd/m², delivering high brightness that ensures clear visibility even under strong ambient lighting conditions. Although the contrast ratio is rated at 300:1, it provides sufficient distinction between visual elements for applications involving graphical interfaces, data visualization, and control panels. While this contrast level may not match high-end multimedia displays, it is well-suited for standard industrial, automotive, and instrumentation use.
The module employs a-Si TFT-LCD technology in a full-color format and supports 262K colors through a Parallel RGB interface (1 channel, 6-bit) using a 33-pin connector—a common configuration that eases integration with various embedded systems and microcontrollers. It operates on a 3.3V power supply, maintaining compatibility with low-voltage platforms and energy-efficient devices.
Backlighting is provided by a CCFL system, ensuring reliable and uniform illumination across the screen, ideal for continuous or long-duration operation. While specific viewing angles and response times are not provided, the panel’s high brightness compensates for this, making it suitable for typical usage environments where visibility and readability are paramount.
Environmentally, the LQ057Q3DC17 is built to function in ambient temperatures ranging from -30°C to 80°C, supporting usage in semi-rugged and industrial conditions where durability and performance are key considerations.
