Replacement Touch Panel - Drop-in?

Post by MMTGuy28 »

I've seen various threads here about Trinity touch panel problems and some attempts at retro fitting other digitizers.

Has anybody found a true drop-in replacement for the Trinity touch panel?

There are some on eBay which might work but I'm not sure and I don't think Triton digitizers are the same as Trinity digitizers.

My Trinity LCD is okay. The touch panel has become a little odd looking in some areas towards the middle and less sensitive in the same area because clearly too much pressure was applied over the years.

It still works correctly with a soft tip tablet stylus though and passes the simple calibration test.

Were these touch panels ever really accurate with a finger or were they always a little sloppy?

Yes, Trinity LCD was always kinda sloppy, requiring your own learned finger technique to use effectively, and it had a slow redraw rate.

I guess it was of its era with early touch LCD technology of its day - truly ground breaking and futuristic of its time, but pales in comparison to the pin-sharp accuracy, detail and draw rate of something like a modern iPad that we're used to thesedays.

Thanks for the info Timo.

So then I gather frustrated users would mash the glass touch panel so much that it got micro stress fractures and started losing sensitivity and looking strange.

These things should have come with a stylus to begin with!

Nah, not that bad, it's still highly usable, I had no problems in using it, my mis-clicks are minimal, it's just a tad clunky when you compare it to modern/current standards (like iPad) given it's 24 years old. Got my Trinity in 1998, and the LCD is still intact and in identical condition to when I bought it.

I think on iPad, for example, the physical 'hit-area' of graphic buttons are actually larger than they're visually shown on the LCD, effectively to idiot-ify the selection process and allow for mistakes/tolerances slightly outside the buttons to still work, whereas the visual button 'hit-areas' on Trinity's LCD are more surgically confined.

I don't have your problem though, it sounds like someone could've stacked something weighty onto your LCD.

I believe user "SpaceCowboy" on the forums here has replaced various screens for the Trinity so it may be worth viewing his posts here in the past (such as this), or maybe send him a message if he wouldn't mind: http://www.korgforums.com/forum/phpBB2/ ... le&u=11814

I can't decide if the flawed look of my LCD is just a stressed touch panel or partially the LCD as well. The only way to find out is to remove it. That's a sizeable job.

Thanks for the link. I'll check that out.
