Engineered with a projected capacitive multi-touch panel, an advanced touch controller board, and a high-performance LED backlight system, this display solution offers responsive 10-point touch functionality, high contrast ratio, wide color gamut, and vivid imagery for premium human-machine interface applications.
The module features SXGA resolution (1280 x 1024 pixels) with 16.7M colors (8-bit), providing sharp, detailed imagery for content-rich displays. The 2-channel LVDS interface ensures stable, high-speed signal transmission with dual-pixel architecture. With 72% NTSC color gamut, 1000:1 contrast ratio, and a fast 5ms response time, this display delivers exceptional image quality and smooth motion performance. The projected capacitive touch panel supports 10 simultaneous touch points with USB and RS232 interface options, and is compatible with Windows, Linux, and Android operating systems.
Note: This module does not include an integrated LED driver board. The LED light bar requires an external driver board (recommended OVP: 10% higher than maximum LED string voltage).

Important Note – External LED Driver Required
This display module does not include an integrated LED driver board. The LED light bar requires an external driver board capable of driving 4 strings of LEDs (11 LEDs per string, 44 total). Key driver design recommendations:
- Analog dimming is strongly recommended for wavy noise-free backlight control
- Over Voltage Protection (OVP) should be set at least 10% higher than the maximum LED string voltage (33.7V × 1.1 = 37.07V minimum)
- If PWM dimming is used, it is recommended to synchronize the PWM signal with the frame frequency
- LED string current: 50mA (typical), 53mA (maximum)
- LED string voltage: 27.2V to 33.7V
Applications
- Industrial Control Panels and HMIs
- Medical Display Systems
- Professional Workstations
- Factory Automation Systems
