Yamaha S90 Graphic LED Display Upgrade.
White/Black or White/Blue available. (Negative)
These NEW Custom LED displays have a number of unique design features.
1. Custom Japanese FFSTN (negative) Tri-Axis LCD panel for improved side to side (lateral) and 6o’clock desktop/keyboard view.
The White/Black and White/Blue looks great sat in the front panel of the S90. Colour choice will depend on personal preference. Both types are ready to ship. Say bye bye to that awful green LCD forever !
2. Optimised display contrast to match the existing S90 contrast control.
Display contrast is perfect @ the midway setting on the Yamaha contrast control with both displays. This was possible by analysing the characteristics of the old display and replicating its VOP specification. These things are possible with custom designs.
The end result is a display that requires NO modifications, resistor change etc to correct the contrast. Display will arrive ready to Plug N Play !
3. Oversized LED backlight.
Largest possible backlight footprint, keeping LED’s away from the viewing area to avoid unwanted lightspot. The result is a flat, even background / border with minimal imperfections. With these negative displays, the backlight design was very important. If the border was patchy and uneven due to LED lightspot, it would ruin the look of the display.
4. Custom AA optomised metal bezel.
The metal bezel on this display has been specified to within 1mm of the active viewing area.This is an unusual feature not found on any other display. The result when combined with the oversized LED backlight is a perfect looking negative display, with a flat black border. The oversized AA optomised metal bezel can be seen pictured last listing pic.
5. Custom 5000K Pure White LED’s.
The LED’s used on this display are pure white 5000 Kelvin types. They were specifically requested. I wanted pure white light to maximise the display contrast. Combined with the backlight design, custom bezel dimensions and the highest quality ‘FF’ double film compensation / polarizers. The final result is a display that looks nearly like an OLED, nearly ! Its as close as it’s possible to get with a Negative Black LCD.
Its very difficult to get the black display ‘right’
A significant number of revisions were required during design to achieve this aim.
Marginal gains philosophy was applied to everything, the collective result is, indisputably, the best looking Negative Black LCD available.
6. Fully adjustable backlight dimmer.
This feature is absolutely necessary with the black display. The blue display is not so fussy. Before it ships, the brightness will be set to the level ‘i’ think is correct for the black FFSTN glass. You can, ofcourse, adjust it further to either brighten (anticlockwise) or dim (clockwise) trick is, not to boost it too much. When its clearly readable @ arms length, it’s bright enough. There is a point, a sweetspot, where the graphics are not too bright and not too dim, the background is as black as possible and it looks amazing. Armed with the backlight dimmer. Its possible to dial in this sweetspot perfectly. It simply needs fine tuning. The dimmer is located on a long ribbon cable, adjustment is possible with a small screwdriver. The display can be mounted, connected up, keyboard fully reassembled, then display switched on and backlight brightness set up from your normal viewing position. When the brightness is set to your liking, the trimpot is tucked inside, out of the way. Its purpose is ‘set and forget’ only !
I started work on these negative Yamaha displays around July’18 after completing the roland jd.jv, xp etc They’ve been technically difficult to sort out due to the old obsolete TAB display Yamaha used as standard. Pretty much everything was designed to the same philosophy as my roland display. I used the same glass/bezel tricks on both to maximise the performance. Both have the same Tri-Axis glass produced in Japan, designed to maximise the viewing angles. A lot of time and effort has went into designing and manufacturing these special Yamaha displays. The pursuit of perfection, means the display is built by 2 different companies. One to produce the special Tri-Axis glass. The other, the chip on board and final assembly. The selling price is a reflection of that whole process and ultimately what you’ll recieve, the best looking, best performing, highest quality display for your S90.
The display will arrive, ready to Plug N Play !
NO soldering is required !
NO modifications are required !
Simply, bolt it in, connect it up, reassemble then switch on and adjust the backlight dimmer from your optimal viewing position.
**Some customers prefer the displays very bright, if that’s your preference, you should choose the White on Blue. The background is a beautiful blue at every brightness setting**
***This display is specifically configured to upgrade your S90. The viewing angle is set during manufacture @ 6o’clock view. Correct for a desktop/keyboard instrument. Its important to fit the correct type, otherwise the look and functionality of the display will be badly compromised. Both displays have a 6o’clock viewing angle***
