Overview

LQ057Q3DC12 Sharp 5.7 inch 320*240  LCD  Display LCD

The Sharp LQ057Q3DC12 is a 5.7-inch active matrix TFT-LCD display module with a resolution of 320 × 240 pixels (QVGA). It features a transmissive display mode with normally white operation. The active area measures approximately 115.2(W)×86.4(H) mm, with overall outline dimensions of roughly 144(W)×104.6(H)×13.5(D) mm. The panel supports 18-bit parallel RGB interface (6 bits per color), capable of displaying up to colors. Logic power supply is 3.3V or 5.0V (selectable), with typical power consumption around 1.5W to 2.5W. The module utilizes a single CCFL (Cold Cathode Fluorescent Lamp) backlight, requiring an external inverter with typical lamp current of 5.0 mA and lamp voltage of approximately 350 Vrms to 400 Vrms. Operating temperature range is -30°C to +80°C, with a storage range of -30°C to +80°C. The module typically features a 33-pin or 40-pin FPC/connector interface for signal integration.

FAQ:

What is the brightness of this screen? Is it clear enough to read in a brightly lit factory?

The typical brightness of the LQ057Q3DC12 is 500 cd/m². While not an ultra-high brightness display, its industrial-grade contrast ratio 350:1) ensures excellent readability in standard factory lighting conditions.

My equipment is installed in a high-temperature environment. What is the operating temperature range of this display?

This model is a wide-temperature industrial display with an operating range of -25°C to +70°C and a storage range of -30°C to +80°C, making it ideal for harsh industrial environments.

If the backlight fails in the future, can the backlight tube be replaced separately?

This screen uses a single CCFL backlight. While the tube can be disassembled and replaced, we recommend it be done by professionals or by replacing the backlight module directly to ensure uniform display quality.
