SHARP LQ10D321

The Sharp LQ10D321 is a rugged 10.4-inch a-Si TFT-LCD module developed for industrial and commercial applications where dependable display quality and long service life are essential. It offers a VGA resolution of 640 × 480 pixels with a 4:3 aspect ratio and an active display area of 211.2 × 158.4 mm, making it suitable for industrial HMIs, CNC systems, medical instruments, process control equipment, and embedded monitoring devices. The module size is approximately 245 × 179.4 × 10 mm.

The display uses TN, Normally White, Transmissive TFT technology with RGB vertical stripe configuration and supports up to 262K colors through a 6-bit signal structure. It provides a typical brightness of around 80 to 200 cd/m² depending on the backlight condition and refurbishment status, along with a contrast ratio between 100:1 and 250:1. The panel is designed for landscape orientation and uses a 31-pin Parallel RGB (1-channel, 6-bit) TTL interface for signal input.

The LQ10D321 is originally equipped with CCFL backlighting and is commonly available with one or dual CCFL lamps depending on the production version. Many industrial users now upgrade the original CCFL system to LED conversion kits for longer service life, lower power consumption, and easier maintenance. Some LED upgrade kits can extend backlight life beyond 100,000 hours.

The module typically operates on either 3.3V or 5V input voltage and includes a 31-pin connector for the display interface. Community discussions around older Sharp LCD modules often note that verifying exact connector pinout, inverter compatibility, and mounting dimensions is important when replacing or repurposing industrial display panels.
