Technical Specifications

*Backlight life is listed as 100,000 hours in the current product specification. Mitsubishi technical documentation for the AC121SA01 also references a typical LED life of 60,000 hours. For engineering or replacement purposes, verify the applicable specification for the exact unit.

12.1-Inch SVGA Industrial Display

The Mitsubishi AC121SA01 features a 12.1-inch display with 800 × 600 SVGA resolution and a traditional 4:3 aspect ratio. The approximately 246 × 184.5 mm active area provides sufficient space for displaying machine parameters, monitoring information, control menus, graphs, and other industrial interface elements.

Its 12.1-inch format is suitable for equipment where a larger viewing area is required while maintaining a compact industrial panel design.

450 cd/m² Brightness and 800:1 Contrast

The AC121SA01 offers a typical brightness of 450 cd/m² and an 800:1 contrast ratio. These specifications provide good image visibility and distinction between display elements in industrial and professional environments.

The panel also supports 262K colors using 6-bit input or 16.7 million colors using 8-bit input, with approximately 72% NTSC color saturation.

Wide Viewing Angles

The AC121SA01 has a specified viewing angle of approximately 80° left, 80° right, 60° up, and 80° down at CR≥10.

This wider viewing range can be useful in industrial environments where operators may view the display from different positions around a machine or control station.

LVDS Interface with 20-Pin Connector

The Mitsubishi AC121SA01 uses an LVDS 1-channel, 6/8-bit digital interface with a 20-pin connector. The LCD operates from a typical 3.3V supply.

When replacing an existing LCD, the connector type alone should not be used to determine compatibility. The pin assignment, LVDS configuration, signal timing, power requirements, and host controller specifications should all be verified before installation.

Integrated WLED Backlight

The AC121SA01 incorporates a WLED edge-light backlight with an integrated LED driver. Unlike older industrial LCD modules using CCFL lamps and external inverters, this configuration provides an integrated LED-based backlight system.

The listed product specification states a backlight life of up to 100,000 hours, while Mitsubishi documentation identifies a typical LED life of 60,000 hours. Actual service life can vary depending on operating conditions and usage.

Antiglare Surface and 3H Hard Coating

The display uses an antiglare surface treatment with 3H hard coating. The antiglare finish helps reduce reflections from ambient light, while the hard coating provides additional protection against surface scratches during normal handling and operation.

This surface treatment can be useful for industrial control interfaces and equipment installed in environments with variable lighting conditions.

Wide Operating Temperature Range

The AC121SA01 is specified for an operating temperature range of -30°C to 80°C and a storage temperature range of -30°C to 80°C.

This wide temperature specification allows the panel to be considered for industrial environments with significant temperature variations, subject to the operating limits of the complete equipment system.

Industrial Applications

The Mitsubishi AC121SA01 can be used in systems requiring a 12.1-inch SVGA TFT-LCD with LVDS connectivity and an integrated LED backlight.

Typical applications include:

·        Industrial automation equipment
