Hey everyone,
I’ve been working on a DIY audio project where I’m building a custom front panel interface for an amplifier. I wanted to use an ultra-wide bar-type LCD as the main display for volume level, EQ visualization, and input selection.
Recently I found this 13.6-inch 1920×168 CTP touch bar LCD module that seems ideal for the layout I’m trying to achieve:
13.6 inch 1920x168 CTP bar LCD module
It supports 30-pin eDP, 500 nits brightness, and a capacitive touch panel, which sounds perfect for integration into an audio device’s control surface.
However, I’m facing a few technical challenges that I’m hoping someone here might have insights on:
-
eDP to SBC connection – Has anyone successfully interfaced a display like this with Raspberry Pi or other SBCs that only have HDMI or MIPI output?
-
Touch driver compatibility – Since this module uses a CTP interface, what’s the best way to handle USB touch input under Linux (RetroPie or Raspbian)?
-
UI rendering optimization – With such a low vertical resolution (168 px), what would be the most efficient way to design a readable and functional interface for controls like sliders or meters?
-
Mounting and enclosure design – Any advice on integrating an ultra-wide panel into an existing amplifier case without introducing noise or thermal issues?
If anyone here has experimented with similar bar-type displays or built audio front panels using touch LCDs, I’d love to hear your setup details and lessons learned.
Appreciate any pointers or shared experiences!
