LG Display LB315WRM-SVA1 32-Inch 4K LCD Panel

The LG Display LB315WRM-SVA1 is a 32-inch TFT (Thin-Film Transistor) LCD panel designed for professional applications requiring high brightness, ultra-high definition resolution, and wide viewing angles. This panel delivers 3840 × 2160 pixel UHD (4K) resolution at a 16:9 aspect ratio, providing exceptional detail for industrial control room displays, medical diagnostic monitors, public information signage, and high-end video walls. With a typical brightness of 1000 cd/m², it is suitable for environments with high ambient light, such as broadcast studios, airport terminals, and outdoor kiosks. The LB315WRM-SVA1 is manufactured by LG Display, one of the world's leading producers of large-format LCD panels.

Technical Specifications

The LB315WRM-SVA1 has a diagonal screen size of 31.5 inches (80.01 cm). Resolution is 3840 × 2160 pixels (UHD). Panel type is a-Si TFT-LCD with IPS (In-Plane Switching) technology, which provides consistent color reproduction and contrast across a wide viewing angle. Brightness is 1000 cd/m² (typical), contrast ratio is 1300:1 (typical). Viewing angles are 89° in all four directions (left, right, up, down). Color depth is 16.7 million colors (8 bits per color). Response time is 14 ms (typical, gray to gray). Backlight type is WLED (White Light Emitting Diode) with a dimming function. The panel uses a V-by-One (Vx1) interface, an 8-lane high-speed serial interface developed for high-resolution displays. The surface is treated with anti-glare (Haze 25%) and hard coating (3H) to reduce reflections and protect against scratches. Pixel arrangement is RGB vertical stripe. Display mode is normally black (IPS mode). Operating temperature range is 0°C to +50°C, with storage from -20°C to +60°C. The display area is 697.306 mm (width) × 392.234 mm (height). External dimensions are 730.7 mm (width) × 425.2 mm (height) × 23 mm (depth). Typical weight is 6.00 kg, with a maximum of 6.30 kg.

Display Performance

The LB315WRM-SVA1's IPS technology provides consistent color and grayscale performance regardless of the viewer's position, a critical feature for control room or medical applications where the display may be viewed from multiple angles. The 1000 cd/m² brightness allows the display to overcome high ambient light levels, which is particularly valuable for outdoor kiosks or brightly lit industrial environments. The 1300:1 contrast ratio ensures that dark content in images and video is rendered with depth and detail, while white content remains bright and clean. The 8-bit color depth supports 16.7 million colors, sufficient for most professional video and graphics applications. The 14 ms response time is adequate for video playback and general-purpose display applications. Color temperature is 6485K, consistent with industry standards for natural white reproduction.

Interface and Compatibility

The V-by-One (Vx1) interface is a high-speed serial interface developed specifically for large-format, high-resolution LCD panels. It reduces the number of signal pairs required compared to older LVDS interfaces, simplifying the design of the timing control (TCON) board. The 8-lane configuration supports the full UHD resolution at 60 Hz refresh rate without requiring compression or data rate reduction. This interface is supported by a wide range of timing control boards, scaler boards, and embedded systems designed for industrial display applications. Compatible single-board computers and embedded systems (such as the SBC NPA-2009) can directly drive this panel. This open-architecture compatibility allows system integrators to pair the LB315WRM-SVA1 with a variety of video processing boards, from off-the-shelf industrial computers to custom-designed controllers.

Applications

The LB315WRM-SVA1 is designed for professional display applications that demand high resolution, brightness, and reliability. Typical applications include industrial control room displays (SCADA systems, process visualization), medical diagnostic monitors (surgical displays, PACS viewing stations), public information signage (airport flight information, train station departure boards), digital signage in high-ambient-light environments (retail store windows, outdoor kiosks), broadcast studio monitors, and video wall components where the 31.5-inch size and slim bezel allow multiple panels to be tiled for larger displays. The panel's high brightness and wide viewing angles are also beneficial for information kiosks located in shopping malls, hotels, and convention centers.

Installation and Physical Characteristics

The panel's dimensions of 730.7 mm × 425.2 mm × 23 mm make it relatively slim for its size, enabling integration into shallow enclosures. The weight of approximately 6.0 kg ensures that the panel can be supported by standard mounting frames and brackets. The anti-glare (matte) surface treatment is rated at 25% haze, providing effective glare reduction without excessive diffusion that would degrade image sharpness. The 3H hard coating protects the surface from scratches during cleaning and routine handling. The panel uses LED backlight technology, which eliminates the need for high-voltage inverter boards and CCFL tubes, reducing overall system complexity and improving long-term reliability. The WLED backlight also contributes to lower power consumption compared to traditional CCFL backlights. The edge-lit or direct-lit configuration ensures uniform brightness across the entire display area.

Conclusion

The LG Display LB315WRM-SVA1 32-inch 4K LCD panel provides a combination of ultra-high resolution, high brightness, and wide viewing angles suitable for professional display applications. Its V-by-One interface, industrial-grade temperature range, and IPS technology make it a versatile component for system integrators building control room displays, medical monitors, and high-end signage solutions. With 1000 cd/m² brightness and 1300:1 contrast ratio, this panel delivers clear, vibrant images even in challenging lighting conditions.
