The DBT043BPSA-01P is designed around a 4.3-inch form factor that provides enough display area for operating parameters, numerical information, menus, icons, status indicators, and basic graphical interfaces while keeping the overall equipment footprint compact.
The 480 × 272 pixel resolution is suitable for many industrial HMI and instrumentation applications where the primary requirement is clear presentation of operational information rather than high-resolution multimedia content. The 16.7M color capability also allows system designers to distinguish different operating states through graphical elements, status indicators, and interface colors.
Its Normally Black display mode provides a dark display appearance when the LCD is not actively displaying image content and can support interface designs that require a high-contrast visual presentation.
One of the key characteristics of the DBT043BPSA-01P is its specified ALL viewing direction. This provides greater flexibility when positioning the display within industrial equipment.
For control panels, instruments, automation equipment, and embedded interfaces, operators may not always look directly at the display from a fixed position. A display with broad viewing performance can help maintain consistent visual information when viewed from different directions.
This characteristic can be particularly useful for equipment installed in production areas, control cabinets, testing stations, or operator interfaces where the viewing position may change during operation or maintenance.
The DBT043BPSA-01P uses a 24-bit RGB parallel interface, providing dedicated RGB data channels together with timing and control signals.
The interface includes:
R0–R7 RGB data channels
G0–G7 RGB data channels
B0–B7 RGB data channels
Pixel clock (PCLK)
Horizontal synchronization (HSYNC)
Vertical synchronization (VSYNC)
Data enable (DE)
Display standby/control signals
This interface structure allows engineers to connect the LCD module with compatible display controllers, processors, and industrial control architectures.
The module operates from a 3.3 V typical supply, with a specified operating range of 3.0–3.6 V. Designers should follow the module's electrical specifications, timing requirements, power sequencing requirements, and absolute maximum ratings when developing the host system.
The DBT043BPSA-01P incorporates a white LED backlight with a 5 × 2 configuration, using 10 LEDs in total.
The backlight provides the illumination required for displaying text, numerical information, graphics, and control interfaces. Its compact construction is suitable for equipment where the LCD assembly must be integrated into a limited mechanical space.
The backlight and LCD should be evaluated together with the final enclosure, viewing environment, optical structure, and system design. For applications with specific brightness requirements, Aptus can discuss display customization options based on project requirements.
The module provides touch-panel control pins identified as XR, YD, XL, and YU. These connections allow a resistive touch solution to be considered when touch operation is required.
The standard DBT043BPSA-01P specification does not mean that an integrated touch panel is included as a default configuration. Instead, the available touch-related interface provides a foundation for integrating an appropriate resistive touch solution into a customized product.
For equipment manufacturers requiring a complete touch display assembly, customization can be discussed according to the mechanical structure, cover lens requirements, touch technology, and system integration requirements.
The DBT043BPSA-01P is specified for an operating temperature range of −20°C to +70°C, with a storage temperature range of −30°C to +80°C.
This temperature range makes the module appropriate for many controlled industrial environments, automation systems, instrumentation products, and professional equipment.
Temperature performance should always be evaluated according to the complete equipment design. The final operating conditions can be affected by enclosure construction, internal heat generation, backlight operation, installation position, and other components surrounding the LCD module.
The DBT043BPSA-01P is intended for industrial and professional applications where a compact TFT-LCD module is required. Typical applications include:
The 4.3-inch size makes this LCD module suitable for compact human-machine interfaces used in industrial machinery and automation equipment. It can display machine parameters, operating status, alarms, menus, process information, and configuration interfaces.
The 480 × 272 resolution provides sufficient space for basic graphical HMI layouts while keeping the module compact.
Automation equipment often requires local displays for monitoring operating conditions and configuring machine parameters. The DBT043BPSA-01P can be integrated into PLC-based equipment, automation controllers, production machinery, and customized industrial control systems when the host controller supports the required RGB interface.
Compact measurement equipment can use the module to present numerical readings, measurement parameters, configuration menus, and equipment status. The lightweight 57 ± 5 g construction and 4.10 mm module thickness can help simplify mechanical integration into portable or benchtop professional instruments.
The LCD can serve as a local information interface for industrial meters, energy monitoring equipment, environmental monitoring devices, and other professional measurement systems. The display area provides sufficient space for numerical values, status information, icons, and simple graphical elements.
Beyond standard HMI applications, the module can be integrated into customized professional equipment where its 4.3-inch size, RGB interface, compact dimensions, and temperature specifications match the system requirements.
The product is positioned for industrial and professional equipment rather than consumer electronics or aviation applications.
