Technical Specifications

The exact LTM12C289S product listing confirms the 12.1-inch size, 800 × 600 resolution, a-Si TFT-LCD construction, RGB vertical stripe arrangement and 246 × 184.5 mm display area. Detailed electrical and optical characteristics above are based on available LTM12C289 series technical references.

12.1 Inch 800 × 600 SVGA Display

The Toshiba LTM12C289S features a 12.1-inch diagonal display with an 800 × 600 SVGA resolution. Its 246 × 184.5 mm active area provides the traditional 4:3 format commonly found in industrial computers and legacy machine interfaces.

With approximately 82 PPI, the display is suitable for presenting machine parameters, numerical readings, menus, status indicators, alarms, measurement values and graphical control interfaces.

The 800 × 600 resolution is particularly relevant when replacing older equipment designed around SVGA output. However, resolution and screen size alone do not establish compatibility. The interface, connector pinout, active area, physical dimensions, mounting arrangement, voltage and backlight system must also be matched.

Display Technology

The LTM12C289S uses amorphous silicon TFT-LCD technology. Available technical references for the LTM12C289 series identify the panel as TN, Normally White and Transmissive.

The panel uses an RGB vertical stripe pixel arrangement and supports 262K colors through its 6-bit display interface. The traditional TN configuration is characteristic of many industrial and legacy TFT-LCD modules from this generation.

Because the LTM12C289S is an older display design, replacing it with another 12.1-inch TFT panel should not be based solely on size and resolution. Different display technologies can have different electrical interfaces, timing requirements, optical characteristics and pin assignments.

Brightness and Contrast

Available technical references for the LTM12C289 series specify a typical brightness of 250 cd/m² and a typical contrast ratio of 250:1.

The available series specifications list typical viewing angles of approximately 60° left, 60° right, 50° upward and 50° downward.

These specifications describe the optical characteristics of the panel and should be considered when replacing the display in equipment where viewing position and ambient lighting are important.

Interface and Connector

The LTM12C289 series uses a legacy parallel RGB interface rather than the LVDS interface found on many later industrial TFT-LCD panels. Available technical references identify the signal interface as 1-channel, 6-bit parallel RGB and specify a 30-pin connector.

The typical LCD supply voltage is 3.3V. The display timing specification for the LTM12C289 identifies an 800 × 600 active display period and timing parameters based on the panel's RGB input clock.

This interface configuration is particularly important for replacement applications. A modern 12.1-inch LCD with an LVDS or eDP interface cannot be assumed to be a direct substitute.

Before connecting the LTM12C289S, verify:

• Exact connector pinout
• RGB signal assignment
• 6-bit configuration
• Pixel clock requirements
• Horizontal and vertical timing
• LCD supply voltage
• Connector orientation
• Controller output compatibility
• Backlight connection

A 30-pin connector alone does not guarantee compatibility. Another 30-pin display may use completely different signal assignments or electrical requirements.

Backlight

The LTM12C289 series uses two CCFL lamps for backlighting. Available technical references identify the backlight as an edge-light configuration with replaceable lamps and approximately 50,000 hours of typical lamp life.

The CCFL lamps require an appropriate high-voltage inverter to operate. The inverter specifications must be matched with the lamp voltage, current and frequency requirements of the LCD.

This is an important consideration when replacing the LTM12C289S. A modern LED-backlit 12.1-inch LCD may have the same resolution but will require a different backlight power and control arrangement.

The Toshiba Matsushita documentation for the related LTM12C289-series-compatible LTD121C30S also confirms the use of twin CCFLs and identifies a replaceable lamp structure compatible with the LTM12C289 series.

Mechanical Dimensions

The LTM12C289 series is listed with an outline size of approximately 278.3 × 209 mm and a depth of approximately 14 mm. The active display area is 246 × 184.5 mm, while the bezel area is approximately 249 × 187.5 mm.

The physical dimensions are important when installing the LCD into an existing equipment enclosure. Check the following before ordering a replacement:

• Overall width
• Overall height
• Panel thickness
• Active area
• Bezel opening
• Mounting-hole locations
• Connector position
• Cable routing
• Rear clearance
• CCFL inverter placement

A different 12.1-inch SVGA panel may have a different enclosure size, mounting arrangement or connector location even when its resolution is identical.

Operating Temperature

Available technical references for the LTM12C289 series specify an operating temperature range of 0°C to +50°C and a storage temperature range of -20°C to +60°C.

These limits apply to the LCD module. The controller, CCFL inverter, power supply, cables and equipment enclosure may have separate operating temperature specifications.

For equipment operating in demanding environments, the complete display assembly should be evaluated rather than relying only on the LCD panel's temperature rating.

Industrial Applications

The Toshiba LTM12C289S is a 12.1-inch SVGA TFT-LCD module designed around a legacy parallel RGB interface and CCFL backlight system. Its format is relevant to equipment that requires this specific display configuration. The model is listed for industrial PC applications in available panel references.

Potential applications include:

• Industrial PCs

• Mounting holes and mounting arrangement
• Connector type and location
• 30-pin connector configuration
• Complete RGB pinout
• Parallel RGB interface
• 6-bit signal configuration
• Pixel clock
• Horizontal timing
• Vertical timing
• 3.3V supply requirement
• CCFL backlight configuration
• Two-lamp configuration
• CCFL inverter requirements
• Lamp voltage and current
