Technical Specifications

The above specifications follow the current product specification available for the AT070TN83-V.1. Some third-party references list different brightness, contrast, and dimensional values for this model, so the exact panel revision and applicable datasheet should be verified for engineering-critical replacement requirements.

7-Inch WVGA Industrial Display

The Innolux AT070TN83-V.1 features a compact 7.0-inch screen with an 800 × 480 WVGA resolution and approximately 133 PPI pixel density. Its active display area of 152.4 × 91.44 mm provides sufficient space for graphical interfaces, machine information, status screens, controls, and monitoring data while maintaining a compact overall panel size.

400 cd/m² Brightness and 1000:1 Contrast

With a typical brightness of 400 cd/m² and a 1000:1 contrast ratio, the AT070TN83-V.1 is designed to provide clear image visibility and good distinction between dark and bright areas.

The display supports 262K colors and approximately 50% NTSC color coverage, making it suitable for displaying text, graphics, icons, control information, and other interface elements in embedded and industrial systems.

TN Normally White Display Technology

The AT070TN83-V.1 uses TN, normally white, transmissive TFT-LCD technology. Its specified viewing angles are approximately 70° left, 70° right, 50° upward, and 70° downward at CR≥10.

The panel is therefore well suited to applications where the display is installed in a defined viewing position and operators primarily view the screen from the front.

Antiglare Surface Treatment

The display features an antiglare surface treatment designed to reduce reflections from surrounding light sources. This can improve readability when the panel is used in equipment exposed to indoor lighting, machine lighting, or other ambient illumination.

The antiglare finish is particularly useful for control interfaces where operators need to read displayed information without excessive reflections.

TTL Interface with 40-Pin Connector

The Innolux AT070TN83-V.1 uses a TTL 1-channel, 6-bit signal interface through a 40-pin connector. The typical LCD supply voltage is 3.3V.

For replacement or integration applications, the connector and interface specifications should be checked carefully. A display with the same size and resolution is not necessarily electrically compatible with the AT070TN83-V.1.

Before installation, verify the pin assignment, signal format, timing requirements, power supply, and host controller compatibility.

WLED Backlight with Integrated LED Driver

The AT070TN83-V.1 uses a WLED backlight with an integrated LED driver. The specified backlight life is approximately 20,000 hours.

The integrated driver simplifies the backlight arrangement compared with LCD modules that require a separate external LED driver, although the host system must still meet the specified electrical requirements of the module.

Compact 5.8 mm Panel Depth

With an outline dimension of approximately 165 × 104 × 5.8 mm, the AT070TN83-V.1 provides a compact form factor for embedded equipment and space-constrained display applications.

Its relatively thin module profile can be useful when designing or maintaining equipment where installation space is limited.

Wide Operating Temperature Range

The AT070TN83-V.1 is specified for an operating temperature range of -20°C to 70°C and a storage temperature range of -30°C to 80°C.

This temperature range allows the panel to be considered for a variety of industrial, embedded, and semi-rugged applications, subject to the temperature limits and environmental requirements of the complete system.
