Frequently Asked Questions About LJ640U32

Can I use a standard 640x480 (VGA) screen instead of this 640x400 LJ640U32?

No. 640×400 and 640×480 have different physical active areas, different timing signals, and different pinouts. Using a 640x480 screen in a machine designed for 640x400 will result in a distorted image, black bars, or a completely blank screen. You must use the exact LJ640U32 replacement.

Does this Sharp 8.9" module include a touch screen?

The standard LJ640U32 is supplied as a bare LCD display module without a touch panel. If your original equipment had a touch screen, you will need to carefully transfer the original touch glass and bezel to this new LCD module.

My old screen uses a CCFL backlight. Is this new one LED or CCFL?

Depending on the specific revision and stock, the LJ640U32 may come with its original CCFL backlight or a modern LED upgrade. If your machine has a high-voltage CCFL inverter board, please contact us before ordering so we can match the correct backlight type for your system.

Can I get the datasheet and pinout for the LJ640U32?

Yes, our technical team can provide the official Sharp datasheet upon request. We highly recommend checking the FPC connector pinout against your motherboard before installation.

Need Datasheet or Pricing for Sharp LJ640U32?

Don't let a broken 8.9" screen halt your legacy equipment. Contact our Sharp display specialists today to verify stock and compatibility.
