Frequently Asked Questions

What type of backlight does the LQ057Q3DC02 use?

This specific Sharp model utilizes a CCFL (Cold Cathode Fluorescent Lamp) backlight system. This requires your controller board or motherboard to have a compatible CCFL inverter to power the backlight. Ensure your hardware supports CCFL before ordering, as it is not interchangeable with LED-backlit panels without a driver modification.

Can I use this 5.7" QVGA screen with a Raspberry Pi or modern HDMI board?

The LQ057Q3DC02 uses a Parallel RGB (TTL) interface, which cannot be plugged directly into an HDMI port. However, you can easily use it with a Raspberry Pi or other modern SBCs by purchasing an "HDMI to TTL/RGB" universal LCD controller board configured for 320x240 QVGA. We offer compatible driver boards upon request.

Does the LQ057Q3DC02 come with a touchscreen?

The standard LQ057Q3DC02 listed here is a pure TFT-LCD display module without a touch layer. However, it is frequently paired with a 4-wire resistive touch digitizer in industrial applications. If your equipment requires a touch-bonded version, please contact our sales team, and we can source or customize the compatible touch assembly for you.
