The DBT043BWSA02 V1 is a transmissive 4.3-inch TFT-LCD module featuring an active display area of 95.04 × 53.86 mm and an overall module size of only 105.50 × 67.20 × 3.00 mm.
With 800 × 480 pixels, the display provides sufficient resolution for graphical user interfaces, equipment status information, measurement data, menus, icons, and image-based visualization. Its 16.7 million color capability allows the display to reproduce detailed graphical interfaces and color-coded information.
A key advantage of this model is its 900 cd/m² typical luminance, with a minimum specification of 800 cd/m². Compared with standard low-brightness TFT displays, this higher luminance level can improve readability in bright indoor environments and applications exposed to ambient light.
The display uses a 24-bit RGB parallel interface, providing 8-bit data for each red, green, and blue channel. This interface architecture is widely used in embedded display applications and can be integrated with compatible MCUs, processors, and system-on-chip platforms.
The module operates from a typical 3.3 V supply, with a recommended VDD range of 2.7–3.6 V. Its operating temperature range of –20°C to +70°C further expands its suitability for industrial and professional equipment.
The 4.3-inch size provides a useful balance between screen area and mechanical compactness. With a 105.50 × 67.20 mm outline and 3.00 mm thickness, the module can be integrated into equipment where enclosure space is limited.
The 800×480 WVGA-class resolution provides sufficient pixel density for equipment interfaces, control menus, graphs, measurement information, and graphical dashboards.
The display provides 900 cd/m² typical brightness at the specified backlight drive condition. This makes it particularly useful where conventional 300–500 cd/m² displays may have limited readability under strong ambient lighting.
The 24-bit RGB interface provides independent 8-bit red, green, and blue channels. It supports full-color image transmission and is suitable for embedded hardware architectures using parallel RGB display output.
The DBT043BWSA02 V1 provides viewing angles of approximately 80° in all four directions at CR ≥10. This gives designers greater flexibility when positioning the display within equipment or control panels.
The module is specified for operation from –20°C to +70°C and storage from –30°C to +80°C, making it suitable for many industrial and professional environments.
The white LED backlight is rated for at least 30,000 hours to 50% of initial brightness under the specified operating conditions, supporting long-term equipment deployment.

For engineers integrating the DBT043BWSA02 V1 into a new hardware platform, electrical compatibility is an important consideration.
The module operates with a typical 3.3 V VDD supply, while the recommended operating range is 2.7–3.6 V. The specified input logic levels are based on the supply voltage, with input-high voltage of at least 0.7 × VDD and input-low voltage of no more than 0.3 × VDD.
The 40-pin interface provides connections for the RGB data channels and display timing signals. The RGB interface includes:
The display supports SYNC, SYNC-DE, and DE timing modes, giving system designers flexibility when configuring the display controller.
The typical DCLK frequency is approximately 25 MHz, with a specified range of approximately 23–27 MHz. Developers should verify the exact timing parameters and initialization sequence against the applicable module documentation before hardware production.
The DBT043BWSA02 V1 uses a white LED backlight consisting of 15 LEDs arranged in a 5 × 3 configuration.
At a typical forward current of 60 mA, the backlight has a typical forward voltage of approximately 15.0 V and typical power dissipation of approximately 0.9 W.
The specified brightness is:
For system designers, the LED backlight should be driven using a suitable constant-current circuit or compatible backlight driver. The backlight electrical requirements should be considered separately from the 3.3 V LCD logic supply.
The combination of 800×480 resolution, 16.7 million colors, 1200:1 contrast ratio, and 900 cd/m² typical brightness makes this module suitable for interfaces where information needs to remain visually clear.
The 80° viewing angle in all directions provides flexibility for mounting the display horizontally, vertically, or at an angle. This can be especially useful in industrial equipment where the operator may not always view the display directly from the front.
The typical response time is 30 ms, while the NTSC color ratio is approximately 50%. These characteristics make the module suitable for graphical interfaces, status screens, equipment controls, data visualization, and general embedded display applications.
The DBT043BWSA02 V1 is well suited to compact industrial HMI systems, equipment controllers, automation interfaces, PLC-related displays, and machine control panels. Its wide temperature specification and high brightness support operation in demanding working environments.
The 800×480 resolution and full-color capability can be used for oscilloscopes, electronic test equipment, portable analyzers, multimeters, laboratory instruments, and other measurement products requiring a compact graphical interface.
IoT gateways, edge-computing devices, monitoring terminals, data acquisition equipment, and industrial communication products can use the 4.3-inch module to display system status, sensor data, alarms, and configuration menus.
Its compact size makes the display suitable for smart appliances, control terminals, security equipment, access systems, and other embedded products requiring a dedicated user interface.
Choosing an embedded TFT-LCD module is not only about resolution. Mechanical dimensions, interface compatibility, brightness, thermal conditions, backlight lifetime, supply stability, and long-term availability all affect the success of a finished product.

The DBT043BWSA02 V1 has an 800 × 480 pixel resolution and supports 16.7 million colors.
The specified minimum brightness is 800 cd/m², while typical brightness is approximately 900 cd/m² at the specified backlight drive condition.
The module uses a 40-pin 24-bit parallel RGB interface with RGB data and timing signals including PCLK, HSYNC, VSYNC, and DE.
The recommended VDD operating range is 2.7–3.6 V, with 3.3 V as the typical operating voltage. The LCD logic supply should not be confused with the separate LED backlight drive requirements.
Yes. The specified operating temperature range is –20°C to +70°C, while the storage range is –30°C to +80°C.
The 900 cd/m² typical brightness and wide temperature range make it suitable for some bright-environment and outdoor equipment designs. However, outdoor readability depends on the complete optical stack, ambient sunlight, cover glass, reflections, enclosure design, and system-level thermal management. For direct-sunlight applications, additional optical optimization may be required.
The specification identifies the controller/driver as ST7265 or equivalent. Engineers should verify the actual controller used on samples or production units and confirm the applicable initialization and timing requirements.
Sample availability, lead time, MOQ, pricing, and production schedules can be discussed with the Aptus sales team according to the project requirements.
