For product developers and equipment manufacturers, the DBT156BZN40E055A provides a high-resolution TFT LCD foundation for embedded systems and specialized display equipment. Before integration, engineers should verify interface compatibility, timing requirements, backlight control, mechanical dimensions, and operating conditions against the module's technical documentation.
4K UHD resolution for detailed visual information
The 3840 × 2160 pixel resolution provides a high pixel density on a 15.6-inch display. It is suitable for interfaces that need to show multiple information panels, fine graphical elements, detailed diagrams, or high-resolution visual content without increasing the physical display size.
550 nits typical brightness
The display offers a typical brightness of 550 cd/m². This level is useful for many bright indoor environments, industrial workstations, and professional equipment. Actual visibility depends on ambient lighting, viewing direction, reflections, and the enclosure design. For direct-sunlight applications, the complete system should be evaluated under the intended lighting conditions.
40-pin, four-lane eDP interface
The module uses a 40-pin connector and a four-lane eDP interface with a specified link rate of up to 5.4 Gbps. Host-side compatibility must be confirmed before design-in, including the eDP version and lane configuration, connector pin assignment, timing settings, and supported resolution.
ADS wide-viewing-angle technology
ADS technology supports wide viewing angles, with typical viewing-angle specifications of 85° in the horizontal and vertical directions at a contrast ratio of at least 10. This helps users view information from different positions around a workstation or equipment panel.
Slim mechanical profile
With outline dimensions of 352.26 × 206.88 × 2.7 mm, the module can be considered for designs where installation depth is limited. Mechanical integration should account for mounting points, cable routing, connector clearance, support structures, and protection against pressure on the LCD panel.
Anti-glare surface treatment
The anti-glare surface helps reduce distracting reflections in suitable lighting conditions. It can be useful for industrial control equipment and professional displays exposed to overhead lighting. The final optical result depends on the cover structure, enclosure, ambient light, and viewing conditions.
Specified industrial operating temperature range
The module's specified operating temperature range is −20°C to +60°C, with a storage temperature range of −30°C to +70°C. These ratings should be considered separately: the storage range does not mean the display is intended to operate continuously at those temperatures. Thermal conditions inside the final equipment should be checked during system validation.

Specifications are based on the supplied product information. Confirm the latest datasheet and approved specifications before making final engineering decisions.
The DBT156BZN40E055A is intended for systems that benefit from high-resolution imagery, a slim display structure, and a high-bandwidth digital interface. Its suitability for a specific application depends on the host platform, optical requirements, mechanical design, and operating environment.
Industrial human-machine interfaces often need to present equipment status, process information, alarms, control settings, and data visualizations in one interface. A 15.6-inch UHD display can provide sufficient pixel density for detailed diagrams and multi-panel layouts.
The module can be evaluated for industrial control terminals, machine interfaces, monitoring workstations, and specialized operator equipment. System designers should confirm the host system's eDP output capability and evaluate the display's brightness, viewing angle, and temperature ratings against the installation environment.
Professional equipment may need to display detailed images, graphs, video, or several information windows at once. The 3840 × 2160 resolution supports high-detail content on a relatively compact 15.6-inch panel.
Potential uses include professional monitoring equipment, technical visualization terminals, and specialized image-display systems. The display module itself does not determine the performance of the complete system; image processing capability, signal compatibility, software support, and system calibration remain important considerations.
Embedded equipment sometimes requires a display that can show detailed interfaces while fitting into a defined mechanical enclosure. The module's slim profile and UHD resolution make it a candidate for compatible embedded computing platforms, engineering terminals, and specialized control units.
Designers should check whether the selected platform supports the required eDP configuration natively or through an approved solution. Connector compatibility alone does not guarantee that a host system can drive the panel at its native resolution.
Selecting a high-resolution LCD module involves more than matching the diagonal size and resolution. Before integrating the DBT156BZN40E055A, engineers should evaluate several system-level requirements.
eDP host compatibility: Confirm that the host platform supports the panel's required four-lane eDP configuration and link rate. Check the electrical interface, connector pinout, display timing, and system firmware configuration against the official documentation.
Power and backlight control: The logic supply is specified at 3.3 V typical, within a 3.0–3.6 V range. The LED backlight uses PWM and enable control. The complete power architecture and backlight-control signals should be designed according to the manufacturer's electrical specifications.
Mechanical installation: Allow for the 352.26 × 206.88 × 2.7 mm module outline, connector access, cable bend radius, and mounting clearances. Avoid applying concentrated pressure to the active area, polarizer, or panel edges.
Thermal management: The rated operating temperature is −20°C to +60°C. The enclosure's internal temperature may differ from the surrounding ambient temperature, especially when other electronic components generate heat. Validate the complete system under realistic operating loads.
Optical performance: The 550-nit typical brightness and anti-glare treatment may suit bright indoor environments, but actual readability depends on ambient light, reflections, and viewing direction. Evaluate the assembled equipment rather than relying only on the bare module specification.
Touch and cover integration: The listed specifications do not establish that a touch panel or cover glass is included as standard. If touch input or a customized front structure is required, discuss the intended mechanical and optical configuration with APTUS before finalizing the design.
The native resolution is 3840 × 2160 pixels, also known as 4K UHD. This provides a high pixel density for detailed graphics, fine text, and information-rich interfaces on a 15.6-inch display.
The module uses a 40-pin connector with a four-lane eDP interface. The specified link rate is up to 5.4 Gbps. The host device must support a compatible eDP configuration and the panel's required timing parameters.
The typical 550-nit brightness is suitable for many bright indoor environments and may work in some shaded or semi-outdoor locations. It should not automatically be considered sunlight-readable. Direct sunlight, reflections, enclosure glass, and viewing angle can significantly affect readability, so evaluate the complete assembly in the intended environment.
The specified operating temperature range is −20°C to +60°C. The storage temperature range is −30°C to +70°C. Storage ratings should not be interpreted as operating ratings.
Yes. The ADS display technology has a typical viewing-angle specification of 85° in four directions at a contrast ratio of at least 10. Actual viewing experience may vary with the image, installation angle, and ambient conditions.
