Supply options for the Sharp LQ057Q3DC02
- Original Sharp part: sourced on request. Availability, date code and lead time are confirmed per order; we do not hold stock of third-party panels.
- Alternative from our direct factories: a standard or customized module with the same size and resolution, with the mechanical and electrical differences documented before you order samples.
Standard models with the same resolution
From our direct factories’ catalog. Pinout and outline differ from the LQ057Q3DC02; we confirm fit before sampling.

Replacing a parallel RGB panel
The LQ057Q3DC02 uses Parallel RGB (1 ch, 6-bit). At 320×240 and 60 Hz the pixel clock is about 5.5 MHz. When you move to an alternative, check:
- Timing: horizontal/vertical blanking and DE or SYNC mode must match what your controller generates.
- Colour depth: a 6-bit (18-bit bus) host can drive an 8-bit panel with the low bits tied, and vice versa with dithering.
- Connector and pinout: same pin count does not mean the same pin map; an adapter FPC is often enough.
- Backlight and touch: LED driver, brightness and whether the original had a resistive or capacitive touch layer.
What to send us

Frequently asked questions
Can you supply the original Sharp LQ057Q3DC02?
Yes, on request. We confirm availability, date code and lead time per order. We do not hold stock of third-party panels.
What can replace the LQ057Q3DC02?
A module with the same size and resolution from our direct factories, adapted where needed (FPC, backlight, outline). Send the original datasheet and we propose options with the differences listed.
Where do these LQ057Q3DC02 specifications come from?
From the source linked on this page. CCFL backlight. Always design against the Sharp datasheet revision for your exact part.
