DBC088LCDAEN40L045A 8.8-Inch 1280×320 LVDS TFT LCD Datasheet

DBC088LCDAEN40L045A 8.8-Inch TFT LCD Overview

The DBC088LCDAEN40L045A is an 8.8-inch ultra-wide TFT LCD module designed around a 1280 × 320 RGB pixel format and an LVDS video interface. Unlike conventional 16:9 LCD panels, its 216.96 × 54.24 mm active display area provides an approximately 4:1 panoramic format, making it particularly useful where information needs to be presented across a long, narrow display surface.

The module uses a normally-black IPS-type display structure with wide viewing characteristics and supports 16.7 million colors. Its LCD outline measures 223.36 × 65.34 × 4.85 mm, allowing the panel to be integrated into compact elongated enclosures where vertical installation space is limited.

1280×320 LVDS Display Interface

DBC088LCDAEN40L045A uses an LVDS interface rather than HDMI or eDP at the native panel level. The recommended mating connector is the Hirose FH12-40S-0.5SH, using a 40-pin, 0.5 mm pitch connection.

The LVDS section provides differential channels RXIN0 through RXIN3 together with the LVDS clock pair. The module supports both 6-bit and 8-bit LVDS input selection through the LVBIT signal.

For system timing, the specification defines:

• Resolution: 1280 × 320 pixels
• Typical frame rate: 60 Hz
• Pixel clock: 31 MHz
• Horizontal total: 1440 clocks
• Vertical total: 358 lines
• Horizontal active pixels: 1280
• Vertical active lines: 320

These timing parameters are particularly important when developing a custom LVDS controller board or configuring an embedded processor directly for the DBC088LCDAEN40L045A panel.

Optical Performance

The optical specification lists a 1500:1 typical contrast ratio, with a minimum value of 1000:1.

Viewing angles reach approximately 80° in the top, bottom, left and right directions under CR ≥10 measurement conditions. Combined with the normally-black display mode, this makes the panel more suitable for interfaces that may be viewed from different positions rather than only directly in front of the screen.

The optical table specifies:

• Minimum luminance: 400 cd/m²
• Typical luminance: 450 cd/m²
• Typical contrast ratio: 1500:1
• Typical viewing angle: 80° / 80° / 80° / 80°
• Typical TON response time: 12 ms
• Typical TOFF response time: 12 ms
• Typical luminance uniformity: 80%
• NTSC color gamut: 50%

These characteristics distinguish DBC088LCDAEN40L045A from standard low-brightness consumer bar displays and provide useful optical data for engineers evaluating the panel for embedded HMI or panoramic display designs.

Power and LED Backlight Requirements

The TFT LCD logic operates from a 3.3V typical supply, with a recommended VDD operating range of 3.0V to 3.6V.

The LED backlight is specified separately at:

• Backlight current: 180 mA typical
• Backlight voltage: 10.8–13.6V
• Typical driving voltage: 12V
• Maximum listed backlight power: 2.448W
• LED lifetime: 25,000 hours at 25°C under the specified typical current condition

The datasheet defines LED lifetime as the period until brightness decreases to 50% of its original value under the stated test condition.

This distinction between panel VDD and LED backlight supply should be considered when designing the power architecture for the module.

Capacitive Touch Interface Signals

An important feature of the DBC088LCDAEN40L045A interface definition is the inclusion of dedicated capacitive-touch signals within the connector pin assignment.

The interface includes:

• TP-RES — touch reset
• TP-SDA — I²C data
• TP-SCL — I²C clock
• TP-INT — touch interrupt
• TP-VDD — touch power supply

The specification also defines an I²C clock frequency up to 400 kHz for the touch interface.

This allows an embedded controller to communicate with the touch subsystem independently from the LVDS image data path.

Mechanical Dimensions and Integration

For enclosure and mechanical design, the primary DBC088LCDAEN40L045A dimensions are:

The unusually wide 216.96 mm active width combined with only 54.24 mm active height is one of the defining characteristics of this model. It allows developers to build elongated graphical interfaces without using multiple smaller LCD modules side by side.

Reliability and Environmental Testing

DBC088LCDAEN40L045A is specified for operation from -20°C to +70°C and storage from -30°C to +80°C.

The datasheet also documents a number of reliability tests, including:

• +80°C high-temperature storage for 96 hours
• -30°C low-temperature storage for 96 hours
• +70°C high-temperature operation for 96 hours
• -20°C low-temperature operation for 96 hours
• +60°C / 90% RH high-temperature humidity storage
• -30°C to +80°C thermal shock for 20 cycles
• ±4 kV contact ESD
• ±8 kV air ESD
• 10–55 Hz vibration testing
• 60G / 6 ms mechanical shock
• 60 cm packaged drop test

These published test conditions give engineers additional reference data when evaluating the display for applications that experience temperature changes, vibration or handling stress. The module is also specified as RoHS compliant.
