AUO C070EAN03.1 6.9 inch TFT LCD for Industrial HMI

The AUO C070EAN03.1 is a 6.9-inch WXGA TFT-LCD cell engineered for industrial OEM and ODM integrators who need a compact, wide-temperature display module with a slim mechanical profile. Built on a-Si TFT-LCD technology in an AHVA, normally black, transmissive configuration, the C070EAN03.1 delivers 1280 × 720 (RGB) resolution with 16.7M (8-bit) color depth, 1000:1 typical contrast ratio, and 92% sRGB coverage (CIE 1931). The panel operates from -40 °C to +85 °C with a storage range of -40 °C to +95 °C, making it well suited to harsh, temperature-extended environments. Supplied as a CELL module without an integrated backlight (No B/L), it gives system designers full control over backlight architecture, thermal management, and optical stack-up. Signal handling is based on a single-channel 8-bit LVDS interface with an SPI command/control port, operating from a typical 3.3 V supply, and the module is driven at a standard 60 Hz refresh rate with a maximum response time of 25 ms (Tr+Td). With an outline dimension of 163.8 mm × 89.6 mm, an active area of 156.48 mm × 80.136 mm, and a weight of 0.5 kg, the C070EAN03.1 integrates cleanly into mid-size HMI, instrumentation, and in-vehicle display assemblies.

Does the AUO C070EAN03.1 include a backlight?

No. The C070EAN03.1 is supplied as a CELL module with Backlight Type listed as No B/L. The display cell must be paired with an external backlight unit designed for the application's optical, thermal, and lifetime requirements, which also gives the integrator control over brightness strategy and system heat dissipation.

What is the native resolution and color capability of this panel?

The panel offers a native WXGA resolution of 1280 × 720 (RGB) with 16.7M (8-bit) color depth, a 1000:1 typical transmissive contrast ratio, a 6208K color temperature, and 92% sRGB coverage measured per CIE 1931.

Which interfaces does the C070EAN03.1 support?

The module uses an LVDS interface with 1 channel at 8-bit data width for the video signal, supplemented by an SPI interface for command and control functions. It operates from a typical 3.3 V supply, which allows connection to standard industrial controller and video-processing hardware.

What environmental conditions can the panel withstand?

The specified operating temperature range is -40 °C to +85 °C, and the storage temperature range is -40 °C to +95 °C. These extended limits make the module suitable for equipment deployed in harsh, thermally variable industrial and automotive environments when combined with an appropriately rated backlight and enclosure design.

What are the mechanical dimensions and mounting considerations?

The outline dimension is 163.8 mm (W) × 89.6 mm (H), and the active area is 156.48 mm (W) × 80.136 mm (H). The module weighs 0.5 kg. Integration should be planned around the cell outline, the external backlight stack-up, and the mechanical fixation method selected for the end assembly.

What are the viewing angle and response characteristics?

Viewing angle is specified at 80/80/80/80 (Typ.) at CR ≥ 10 for all four directions, supporting use in equipment with wide viewing requirements. The maximum response time is 25 ms (Tr+Td) at a 60 Hz refresh rate, which is well suited to graphical user interfaces, menus, and data displays rather than full-motion video.

Is this display a CELL or a complete display module?

The panel type is a-Si TFT-LCD, CELL. This means the C070EAN03.1 provides the transmissive normally black AHVA liquid crystal cell only; a backlight, driver integration, bonding, and cover lens are supplied at the system level by the OEM or ODM integrator.
