32 Inch 4K UHD TFT LCD Module with 8-Lane eDP Interface

The DBT315DZN51E060A is a 31.5-inch color TFT-LCD module designed for monitor applications that require high resolution, high brightness, wide viewing angles, and high color depth. It features a 3840 × 2160 UHD resolution, 600 nit typical luminance, 8-lane eDP interface, and support for refresh rates up to 120 Hz. The module uses an oxide active-matrix driving scheme and a transmissive, normally black display mode.

With an active area of 697.3056 × 392.2344 mm and an overall module size of 709.38 × 412 × 12.92 mm, this 31.5-inch LCD module provides a large viewing area while maintaining a relatively slim module profile. Its 8-bit+FRC color architecture supports up to approximately 1.07 billion display colors, making it suitable for applications where detailed images, smooth gradients, and accurate color reproduction are important.

The DBT315DZN51E060A is specified as a monitor-oriented LCD module and is particularly suitable for professional display equipment, commercial monitor products, workstation displays, visualization systems, and other large-format display products requiring 4K image quality.

Key Features

4K UHD Resolution for Detailed Visual Content

The 3840 × 2160 resolution provides four times the pixel count of Full HD. This allows the 31.5-inch display area to present fine text, detailed graphics, high-resolution images, and complex interface information with greater clarity.

For professional monitor designs, the 4K UHD resolution can provide additional workspace while maintaining detailed visual presentation. This makes the module suitable for applications where users need to display multiple windows, detailed graphical interfaces, engineering information, or high-resolution visual content.

600 Nit High Brightness

The DBT315DZN51E060A provides a typical luminance of 600 nit, measured under the specified optical test conditions. The higher brightness level can help maintain image visibility in environments with stronger ambient lighting compared with standard low-brightness LCD modules.

The datasheet specifies a minimum white luminance uniformity of 80%, helping support consistent brightness across the measured display area.

120Hz Refresh Rate Support

The module supports a frame-rate range of 24 to 120 Hz, with 120 Hz as the typical maximum operating point specified in the eDP interface timing table. The response time is optimized for 120 Hz operation, with a typical response time of 14 ms and a maximum specification of 25 ms under the stated measurement conditions.

This combination can be useful for monitor products displaying moving graphics, video content, interactive interfaces, and other applications where smoother image transitions are required.

8-Lane eDP Interface

The DBT315DZN51E060A uses an 8-lane eDP interface for high-speed digital video transmission. The eDP receiver specification lists an eDP frequency of 5.4 Gbps, providing the high-speed interface architecture required by the module.

The main connector is a 51-pin eDP interface, incorporating signal lanes, AUX channels, HPD signals, power connections, and ground connections. System designers should match the host controller, connector configuration, power supply, and eDP timing with the module specification during integration.

Wide Viewing Angle

The LCD module offers an ultra-wide viewing angle. At a contrast ratio greater than 10, the typical viewing angle reaches approximately ±89° horizontally and ±89° vertically.

This wide viewing characteristic allows the display to remain visually accessible from different viewing positions and can be beneficial for large monitor products used by more than one viewer or viewed from different angles.

High Color Depth and Wide Color Gamut

The module supports 10-bit input color depth and uses an 8-bit+FRC output architecture, providing up to approximately 1.07 billion colors. The specified typical color gamut is 92% NTSC.

This color performance makes the module suitable for monitor products where smooth color transitions, detailed images, and broad color reproduction are important considerations.

Technical Specifications

The electrical specifications are based on the datasheet test conditions, including a supply voltage of 12 V and an ambient temperature of 25 ± 2°C.

Mechanical and Integration Considerations

The DBT315DZN51E060A has a module outline of approximately 709.38 × 412 × 12.92 mm, including the side seal. The mechanical drawing specifies mounting provisions including M3 mounting points, allowing the module to be integrated into a compatible monitor enclosure or mechanical structure.

During product development, the host enclosure should provide adequate mechanical support without applying excessive pressure, bending, or twisting to the LCD module. The datasheet also recommends assembly in clean working conditions because dust and oil may affect the polarizer or cause electrical problems.

The module uses a 12 V nominal power supply. The specified power consumption of the LCD section is approximately 23.36 W at 120 Hz typical and 12.98 W at 60 Hz typical, while the LED backlight power is specified separately. System designers should therefore consider the display and backlight power requirements when selecting the final power architecture.

Temperature and Reliability

The specified operating ambient temperature range is 0°C to +50°C, while the storage temperature range is -20°C to +60°C. The datasheet notes that thermal management should be considered in the final product design. Under the specified test setup, the display surface temperature should not exceed 65°C.

The module specification also includes reliability testing covering high-temperature storage, low-temperature storage, high-temperature and high-humidity operation, thermal shock, vibration, shock, and electro-static discharge.

The documented reliability tests include:

• High-temperature storage at 60°C for 240 hours

• Low-temperature storage at -20°C for 240 hours

• High-temperature and high-humidity operation at 50°C and 80% RH for 240 hours

• High-temperature operation at 50°C for 240 hours

• Low-temperature operation at 0°C for 240 hours

• Thermal shock from -20°C to 60°C for 100 cycles

• Random vibration testing at 1.2 Grms

• Shock testing at 50G

• ESD testing at 8 kV air discharge and 4 kV contact discharge

These tests provide engineering reference points when evaluating the module for a finished monitor product, although the test conditions should not be interpreted as a guarantee of the environmental performance of a completed system.
