BRUCE SYSTEMS 6.6" 10-Pin Custom Display Replacement — Case Study
BRUCE SYSTEMS industrial display modules are found on specialized machinery and control panels. These units often use non-standard 10-pin signal interfaces with integrated voltage regulation, making off-the-shelf LCD replacement impossible. This case study documents a fully custom 6.6-inch TFT LCD replacement engineered to match the exact pinout, voltage, and mechanical specifications of the original unit.
The Challenge
The customer's BRUCE SYSTEMS display had failed — the backlight was dead, and the 10-pin connector was damaged. The original display used a specific pinout carrying RGB + HSYNC + VSYNC + DC power, plus a voltage regulation circuit that was integrated into the display assembly. No standard replacement existed. The machine was down, and a full control replacement would cost over $3,000 with extended lead time.

The Solution
We reverse-engineered the 10-pin connector and voltage regulation requirements, then built a custom 6.6-inch TFT LCD module that matches the original signal pinout exactly. The replacement integrates the voltage regulation circuit, so no external modifications are needed. The panel size matches the original display opening, providing a seamless drop-in fit. The complete solution includes the LCD module, pin-to-pin harness adapter, and mounting hardware.
