Overview
WB238-M194L is a color active matrix TFT LCD MDL using amorphous silicon TFT’s(Thin Film Transistors) as an active switching devices. This Open Cell has a 23.8 inch diagonally measured active area with FHD resolutions (1920 horizontal by 1080 vertical pixel array). Each pixel is divided into RED, GREEN, BLUE dots which are arranged in vertical stripe and this module can display 16.7M colors. The TFT LCD panel is adapted for a low reflection and higher color type.
- LVDS interface with 2 pixel / clock
- High-speed response
- Low color shift image quality
- 8-bit color depth, display 16.7M colors
- Wide viewing angle
- DE (Data Enable) only mode
- HADS technology is applied for high display quality
- RoHS compliant
Description
The WB238-M194L is a 23.8″ FHD a-Si TFT-LCD module using dual-channel LVDS — the interface standard for legacy-compatible industrial controllers and existing LVDS-based system designs. The WB238-M194L (250 cd/m²) suits standard indoor applications. The WB238-M412H (800–1000 cd/m²) is specified for high-ambient and outdoor environments. HADS technology delivers wide 89° viewing angles with consistent colour at any approach angle. MOQ 10. Sample within 1 week
Built for LVDS-based system designs
Unlike the eDP-interfaced modules in the DNR Touch range, the WB238-M194L uses 30-pin dual-channel LVDS (8-bit). This makes it the right choice for system designs built around existing LVDS controller architectures, replacement procurement for equipment using LVDS-interfaced panels, and integrators standardising on LVDS across a product line for driver and supply chain continuity. LVDS remains widely supported in industrial control hardware, and this interface choice means the WB238-M194L integrates without requiring an eDP-to-LVDS bridge or controller redesign.
Wide viewing angles, consistent colour — HADS technology explained
The WB238-M194L uses HADS (High Aperture-ratio Drive Scheme) panel technology, a wide-viewing-angle approach comparable in effect to IPS. The result is 89° viewing angles in all four directions with minimal colour shift at extreme angles — relevant for shared-view applications like wall-mounted HMI panels, multi-operator control stations, and public-facing self-service terminals where users approach from varying positions and heights.
Standard or high-brightness — same family, different deployment
The WB238-M194L (250 cd/m²) is the standard configuration for controlled indoor environments. The WB238-M412H (800–1000 cd/m²) is specified for high-ambient and outdoor deployments — kiosks, transit displays, and industrial environments with strong overhead or natural lighting. Both variants share the same 543.08×316.72mm footprint, so a design validated on one configuration carries over to the other without mechanical rework.
Integration notes for hardware engineers
The WB238-M194L operates from a 5V supply (higher than the 3.3V seen on the smaller eDP modules in the range — confirm against your power budget). At 543.08×316.72×10.2mm, this is the thickest module reviewed in the DNR Touch series, reflecting the structural requirements of a larger panel at this size. Response time is 14ms (Tr+Td) at 60Hz — faster than the smaller eDP modules in the range, suitable for applications with more dynamic content. RoHS compliant.
Suitable for integration into
- Legacy industrial HMI and control systems built around LVDS interface architectures
- Wall-mounted and shared-view applications where wide, consistent viewing angles matter
- Medical equipment displays and self-service terminals requiring 24/7 reliability
- High-ambient and outdoor kiosk displays (WB238-M412H, 800–1000 nit variant)
- Replacement procurement for existing equipment using compatible 23.8″ LVDS FHD panels
