What is it?

This is a pin-for-pin compatible nearly exact replacement for the LCD module in the Sharp PC-1246 and PC-1247 pocket computers released in 1984. This LCD will not work in any pocket computer other than the Sharp PC-1246 or PC-1247.

Why did you make it?

Some PC-1246/7 pocket computers suffer from LCD degradation to the point where they are no longer useful. Apparently the seal around the LCD was of poor quality, and over the years moisture gets in and ruins the liquid crystal. The result is a display ranging from a few splotches to complete failure. Or, the LCD might just be broken.

I decided that it was important to bring all these dead PC-1246/7 computers back to life by reverse-engineering the LCD and remanufacturing them.

What makes it special?

These LCDs were custom manufactured by Sharp for the PC-1246/7. Replacement LCDs were never available, and finding a working LCD can involve finding another broken PC-1246/7 to strip it for its hopefully working LCD.

I tried as much as possible to make the fonts and positions used for the indicators as identical to the original as possible.

Instructions for replacement

I've made a video showing how to replace one of these LCDs. Please watch the entire video to see what you are getting into, and how to solve various issues. Instead of the acetone used in the video, I've heard about successes by putting the assembly on a hotplate set to 100C for about three minutes -- be very careful that you don't burn yourself!

Remember, even though you replace the LCD, there still might be something wrong with your PC-1246/7, since there is no way to test the machine without a working LCD.

Please note that because the top polarizer of the replacement LCD is integral to the LCD, while in the original LCD the top polarizer was separate, the bezel around the LCD will be brighter than on the original.
