I am using V-synth GT after a 10-year break. Nostalgia has choked me and here it is again “hello!”, I thought:
- are some experiments possible with installing a much larger screen with touchpad than the original 5.7" (320x240)? because the LCD controller is on a separate sub-board (see p. 39/42)
the motivation is as follows: the Korg Kronos mk1 of that time of design has an 8" display 800x600 SVGA, TouchView. And compared to the authoritative old man Korg OASYS with 10.4" (640 x 480) - a legend from the same 2005, V-synth GT looks quite shameful… :?
Nevertheless, I thought about how to fit the new LCD display into the size of the old plastic frame (the dimensions of the frame opening are 155x135 mm or 205 mm = 7.9~8.0 inches diagonally). or in the case of a wide screen with an aspect ratio not 4:3 but wider, so you may to use the central area width of 19-20 cm and make a rotating frame-transformer like the OASYS:
Since I have experience replacing LCD-chart screens on old synthesizers and new ones memories from replacing non-original touchpads (Korg Z1 touchpad). It would be interesting to hear the opinions of those who have done similar tricks?!
From the datasheet for the C1D13742 LCD controller it is known that:
• Supports TFT panels
• 18/36-bit RGB interface
• Supports resolution up to 800x480 pixels!
Such a controller can provide operability for a TFT display up to 7" and more than 8 inch… (but we must adhere to the possibility of non-destructive replacement due to the existing frame on the front panel of the V-synth)
I have doubts that unless in the V-synth_GT service manual may be another LCDC from this family is installed, but with weaker suitable characteristics C1D13743 is maximum up to 352x440, which is suitable for the declared characteristics of the V-synth GT screen (320x240)
