Custom OLED Display Upgrade for Akai VX90 (Plug & Play)

Breathe new life into your vintage gear with this premium custom OLED display upgrade!

If you own the legendary Akai VX90 analog synthesizer and are struggling with a faded, dead, or unreadable screen, this is the ultimate solution.

Why a standard OLED won't work:
Swapping the display on these specific Akai models is notoriously tricky. You can't just drop in a standard off-the-shelf OLED (like the 1601 type). Due to the character addressing of the old controllers, standard screens will wrap the text in the middle of the line—resulting in a jumbled, unreadable mess.

My Custom Solution:
I designed a dedicated hardware hack/custom PCB that elegantly and permanently solves this character addressing issue.

Why choose this module over others?

• No Stretched Font: Unlike other options (honestly, the only other solution currently on the market), the font on this display is not artificially stretched vertically. The characters have their natural proportions, making the screen look incredibly clean, "cozy," and true to the instrument's vintage aesthetic. Check out the photos!
• The Original Contrast Knob Works!
  Unlike most OLED mods where the contrast potentiometer becomes completely useless, this module keeps it functional. Please note that due to the technological differences between modern OLEDs and vintage LCDs, the brightness changes only within a limited section of the knob's rotation, while the rest of the path remains inactive. However, this active range is perfectly sufficient to let you dial in the ideal glow!
• Beautiful Amber Yellow: The module comes in a stunning Yellow (Amber) color. Classic green 1601 OLEDs are extremely hard to source nowadays, but this yellow gives the unit a fantastic, warm, and premium retro vibe that fits perfectly with the Akai design.

Plug & Play Installation:
No destructive mods, no soldering inside the instrument! The display comes ready to install right out of the box:

• The custom PCB comes with a new 40cm ribbon cable for direct connection. Mounting to the VX90 chassis is straightforward and uses all 4 original screws. On the left side, the screws fit perfectly. On the right side, simply bend the mod PCB gently (it can be done safely without issues) to insert the screws. Note: You will need a slim screwdriver to pass through the holes in the mod PCB to tighten them. Once installed, the module is perfectly secure.

What's included in the box:

• Fully assembled and tested custom OLED display on a PCB.
• Correct wiring (40cm ribbon cable).

Mounting:
Installation is a breeze. You simply reuse the original screws that held the old LCD. Everything drops right into place perfectly.
