The DBT080IXN40L140B is an 8-inch high-brightness TFT-LCD module designed for industrial, outdoor, transportation, automotive, security, and professional equipment applications. It combines 1024 × 768 resolution, 1400 cd/m² typical brightness, LVDS interface, wide-temperature operation, full viewing direction, and AG 3H anti-glare surface treatment in a compact 183 × 141 × 6.3 mm module. Its high luminance and reliable environmental performance make it a practical display solution for equipment that must remain readable and stable in demanding lighting and temperature conditions.
For system designers looking for an 8-inch high-brightness LCD module with LVDS connectivity, the DBT080IXN40L140B provides a balanced combination of optical performance, mechanical integration, electrical compatibility, and long-term reliability.
Display readability becomes increasingly important when equipment is used in bright factories, semi-outdoor environments, transportation systems, or locations exposed to direct or indirect sunlight. A conventional 300–500 nit LCD may become difficult to read under strong ambient illumination. The DBT080IXN40L140B addresses this requirement with a typical luminance of 1400 cd/m², with a minimum specified luminance of 1200 cd/m².
The display provides a 1024 × 768 XGA resolution on an 8-inch panel, producing a practical balance between image clarity, system processing requirements, and power consumption. The normally black display mode provides a dark background when the display is inactive and supports a contrast ratio of approximately 800:1.
The module also uses an AG 3H anti-glare surface treatment, helping reduce distracting reflections from ambient lighting. This is particularly useful for industrial HMI panels, outdoor terminals, control equipment, and other products where the display needs to remain visually accessible from different positions.

Specifications are based on the product specification. Final performance should be validated according to the customer's complete system design and operating conditions.
The primary advantage of the DBT080IXN40L140B is its high-brightness optical configuration.
With 1400 cd/m² typical luminance, the display is designed for applications where ambient illumination is significantly higher than that of a conventional indoor office environment. The minimum specified luminance is 1200 cd/m², providing an additional performance margin for demanding applications.
The display also provides approximately 70% minimum and 80% typical luminance uniformity, helping maintain consistent brightness across the active display area.
Its free viewing direction provides usable visibility from multiple positions. At a contrast ratio of at least 10, the specified viewing angles are approximately 75° minimum and 85° typical in the upper, lower, left, and right directions.
For applications where operators may view a machine interface while standing at different positions, this wide viewing performance can improve usability.
The DBT080IXN40L140B uses an LVDS interface, making it suitable for embedded display systems that require a stable digital video connection.
The module supports 6-bit and 8-bit configuration, with the color-depth mode selectable through the SELB pin. In 8-bit mode, the display can reproduce up to 16.7 million colors.
The product specification defines the relevant interface pin assignments, power requirements, signal timing, and power-sequencing requirements. These parameters are important when integrating the LCD into an existing controller board or designing a customized display system.
For engineering teams, Aptus Display can provide technical documentation needed for integration, including mechanical dimensions, interface information, timing parameters, and electrical characteristics.
The digital supply voltage is typically 3.3 V, while the panel electrical characteristics include AVDD of approximately 10 V, VGH of 18.9 V, VGL of –7.8 V, and VCOM of 3.6 V.
For the LED backlight, constant-current driving is recommended. The typical LED current is 240 mA, with a typical LED voltage of 24 V. The resulting backlight power consumption is approximately 5.76 W.
The LED backlight is specified for a lifetime of at least 30,000 hours to 50% of initial luminance at Ta = 25°C. Actual lifetime can vary depending on operating temperature, drive conditions, system ventilation, and other environmental factors.
The DBT080IXN40L140B is well suited to industrial human-machine interface systems, including factory automation equipment, machine tools, process control panels, and equipment monitoring terminals.
Its 8-inch form factor provides enough screen area for displaying operating parameters, alarms, menus, graphs, and machine status information without requiring the larger footprint of a conventional industrial monitor.
The –20°C to +70°C operating temperature range also supports equipment deployed in environments with significant temperature changes.
The display can be integrated into security terminals, monitoring equipment, access control systems, and professional surveillance products.
Its high brightness allows information such as camera feeds, alarm messages, status indicators, and control menus to remain visible in relatively bright environments.
A display used in industrial or outdoor equipment must be evaluated beyond resolution and brightness. Environmental stability, mechanical reliability, and long-term backlight performance can have a significant effect on the total system lifecycle.
The DBT080IXN40L140B has been evaluated through reliability-related testing covering conditions such as high and low temperature, humidity, thermal shock, vibration, shock, and electrostatic discharge.
The specified operating temperature is –20°C to +70°C, while the storage range extends from –30°C to +80°C.
These specifications make the module a strong candidate for equipment that may experience temperature fluctuations, transportation vibration, or demanding installation environments.
However, display reliability ultimately depends on the complete system. Enclosure design, thermal management, backlight driving, mounting stress, power quality, and operating conditions should all be considered during product validation.

The typical luminance is 1400 cd/m², with a minimum specified luminance of 1200 cd/m². This high-brightness configuration is designed for applications exposed to strong ambient lighting and semi-outdoor conditions.
Yes. The module uses an LVDS interface and supports 6-bit/8-bit configuration through the SELB pin. The 8-bit mode supports up to 16.7 million colors.
The module is suitable for many outdoor and semi-outdoor equipment applications, particularly where high brightness is required. However, the LCD module itself should not automatically be considered a complete outdoor-rated display. The final system should provide appropriate enclosure protection, thermal management, waterproofing, UV protection, and other environmental safeguards where necessary.
The specified operating temperature is –20°C to +70°C, while the storage temperature range is –30°C to +80°C.
The typical LED backlight current is 240 mA at approximately 24 V, resulting in around 5.76 W of backlight power consumption. Constant-current LED driving is recommended.
Aptus Display supports display solution customization and engineering evaluation. Depending on project requirements, customers can discuss brightness, interface, mechanical integration, touch panel, cover glass, cable, driver board, and other display-related requirements with the technical team.
If you are sourcing an 8-inch high-brightness TFT-LCD module for industrial HMI, outdoor equipment, transportation systems, security equipment, professional instruments, or other embedded applications, the DBT080IXN40L140B can be evaluated as a high-visibility LVDS display solution.
