Supply options for the Sharp LQ084V1DG21
- 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 LQ084V1DG21; we confirm fit before sampling.

Replacing a parallel RGB panel
The LQ084V1DG21 uses 31-pin, parallel RGB (18-bit). At 640×480 and 60 Hz the pixel clock is about 22.1 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
The original part number with suffix, a photo of the label and connector, your host processor and the annual quantity. We reply with the original-part availability and one or two alternatives, with the differences listed.
Note: CCFL backlight. The LQ084V1DG21E is a separate variant.
Frequently asked questions
Can you supply the original Sharp LQ084V1DG21?
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 LQ084V1DG21?
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 LQ084V1DG21 specifications come from?
From the source linked on this page. CCFL backlight. The LQ084V1DG21E is a separate variant. Always design against the Sharp datasheet revision for your exact part.
