DBC103LCDHXN20L050A 10.3-Inch Square LCD Overview

The DBC103LCDHXN20L050A is a square-format industrial TFT LCD module designed for
applications requiring equal horizontal and vertical display dimensions.
Unlike conventional widescreen panels, this module uses a
1:1 square display format with 768×768 native resolution.

The panel adopts a normally-black display mode with LVDS signal transmission and supports
16.7 million colors. The compact square structure provides designers with a flexible
solution for industrial interfaces, simulation systems, control equipment and specialized display terminals.

768×768 Square TFT LCD Display Format

The most distinctive feature of the DBC103LCDHXN20L050A is its
768 × 768 square pixel matrix.
The equal horizontal and vertical resolution creates a true square display area suitable for applications
where traditional landscape screens cannot provide the required layout flexibility.

The active display area is:

• Horizontal active area: 184.32 mm
• Vertical active area: 184.32 mm
• Pixel pitch: 0.240 mm × 0.240 mm

Square LCD modules are commonly selected for applications requiring centered graphics,
round instrument interfaces, simulation dashboards, industrial visualization systems and custom HMI designs.

LVDS Interface with JD9168S Driver IC

The DBC103LCDHXN20L050A uses an
LVDS differential interface driven by the integrated
JD9168S driver IC.

The LVDS interface provides:

• LVDS_D0P / LVDS_D0N
• LVDS_D1P / LVDS_D1N
• LVDS_D2P / LVDS_D2N
• LVDS_D3P / LVDS_D3N
• LVDS_CLKP / LVDS_CLKN

The module supports:

• 6-bit LVDS input mode
• 8-bit LVDS input mode
• JEIDA format
• VESA format

This provides compatibility with various LVDS controller boards when correctly configured.

500 cd/m² Brightness and High Contrast Performance

The optical specification defines the following performance:

• Luminance: 500 cd/m² typical
• Contrast ratio: 700 minimum, 1900 typical
• Viewing angle: 85° typical in four directions
• Response time: 25 ms typical
• Luminance uniformity: 70% minimum, 75% typical
• Color gamut: 70% minimum, 75% typical

The high contrast ratio combined with the square display geometry helps maintain clear image presentation
for detailed industrial graphics and information interfaces.

3.3V LCD Power Supply

The TFT LCD operating voltage is specified as:

• Minimum VDD: 3.0V
• Typical VDD: 3.3V
• Maximum VDD: 3.6V

The LVDS interface and power design should be matched with the controller hardware according to the
published pin assignment and power sequence requirements.

LED Backlight Specification

The integrated LED backlight uses:

• Driving current: 590–640mA
• Typical current: 620mA
• Driving voltage: 9V–10.2V
• Typical voltage: 9.6V
• Backlight power consumption: 5.952W typical
• LED lifetime: 30,000 hours

LED lifetime is defined as the time until brightness decreases to approximately 50% of the original value
under Ta=25°C operating conditions.

Wide Temperature Industrial Operation

The DBC103LCDHXN20L050A supports extended temperature operation:

• Operating temperature: -30°C to +80°C
• Storage temperature: -30°C to +85°C

The reliability test conditions include:

• High temperature storage: +85°C, 96 hours
• Low temperature storage: -35°C, 96 hours
• High temperature operation: +80°C, 96 hours
• Low temperature operation: -30°C, 96 hours
• High temperature humidity storage: +60°C, 90% RH, 96 hours
• Thermal shock: -30°C to +80°C, 20 cycles
• Contact ESD: ±4kV
• Air ESD: ±8kV
• Mechanical shock: 60G, 6ms

20-Pin LVDS Connector Assignment

The module uses a 20-pin interface assignment.
Main signals include:

• LVDS differential data channels D0-D3
• LVDS clock differential pair
• VDD3V3 power supply
• GND connections
• UPDN and SHLR display direction controls

The compact connector arrangement simplifies integration into custom display systems while maintaining
high-speed LVDS signal transmission.
