Just wondering what is the resolution of ES920's screen and if it can possibly replace the MP7SE's screen. In the videos, the dimensions seem the same to me.
Trying to get a new display for my Onkyo mini hifi proved to be an absolute P.I.TA - everything had to be spot on. I gave up because it was an odd size.

Learning to play. Consciously incompetent, which apparently is a good starting point.
I'd say they can be! The screen resolution of ES920 is 128 x 64 pixels (OLED) which is the same as MP7SE. Assuming the underlying firmware is the same, there is a chance for compatibility.
I like the OLED screen way more than the annoying blue screen.
The silly thing is black and white is known to be superior in readability scientifically yet many companies use blue when it comes to matrix displays...

The ES920 (OLED) and MP7SE (LCD) both use a 128x64 pixel resolution screen, however the technologies used to render these displays are completely different.
As far as I'm aware, the parts are not interchangeable.
Thanks James. Just wondering if you can give us the part number/names? They are usually some workarounds even if it can't be replaced, there might be a better graphic display like this:
If you look at the video you can see how better the B&W screen is compared to blue... and that's not OLED.

No, I'm afraid not.

Yes, you can also replace the original screens in other retro handheld consoles (Sega GameGear, Atari Lynx, etc.) with brighter, more responsive, lower energy consuming alternatives.
However, unless there is a hidden Easter Egg in the instrument that I'm not aware of, I don't believe it's possible to play Mario on an MP7SE. Therefore, the merits of swapping out the original display with an alternative part are not so compelling.
But bothered by blue, I imagine there might be a piece of plastics to cover and change color and improve contrast.
All color displays I have owned with backlit, the backlit itself is adjustable as well. So you can try back and forth to get blackness and brightness optimized. Maybe that is something firmware for MP7SE can fix if some feel contrast is weak.
As a Kawai rep here, KJ would never encourage us to do such a thing. To figure this out, someone needs to investigate the internals of each keyboard, find the model/brand of the screens, and the chips they use.
The nice thing with OLED is that there is no "backlight". So it won't bother eyes as much as a backlit graphic display (with blue backlight!) does.
BTW blue is the worst light you can use on a screen:
If they are different as KJ says, you’d need is an oscilloscope to ‘sniff’ the serial commands to the LCD driver. This basically decodes what serial commands it’s sending to the chip to display different things. You then tack-on an add-on circuit to translate the commands to a different serial protocol to drive, for example, a nice OLED display.
You could take your MP7SE apart... post detailed pics... perhaps there is a ‘standard’ replacement part out there somewhere with a different coloured backlight.
Even if it’s not possible, it’s all interesting and gets the brain working.

We all know that there will be a time when the keys start failing... that's the time when I will order the plastic bubbles and will investigate the screen
