Technical Specifications

The technical specifications above are based on available Sharp documentation and multiple technical references for the exact LQ121S1LW01 model.

12.1 Inch 800 × 600 SVGA Display

The Sharp LQ121S1LW01 features a 12.1-inch diagonal display with an 800 × 600 SVGA resolution. The 246.0 × 184.5 mm active area provides a conventional 4:3 format, which was widely used in industrial computers, control systems, medical equipment, and embedded equipment.

With approximately 82 PPI, the display provides suitable image detail for machine parameters, numerical readings, menus, alarms, status information, measurement data, and graphical control interfaces.

The 800 × 600 resolution is particularly relevant when replacing legacy equipment designed around SVGA output. However, resolution and screen size alone are not enough to establish compatibility. The active area, physical dimensions, mounting arrangement, interface, pinout, voltage, backlight, and controller requirements should also be checked.

Display Technology

The LQ121S1LW01 uses Sharp's Advanced Super View (ASV) TFT-LCD technology with a Normally Black, Transmissive display mode. This distinguishes it from several other Sharp 12.1-inch LCD models that use different TFT technologies or display modes.

The panel uses an RGB vertical stripe pixel arrangement and provides 262,144 colors through its 6-bit LVDS interface. The Normally Black configuration means the display's optical characteristics differ from Normally White panels, even where screen size and resolution may be identical.

For replacement applications, matching the exact model is therefore important rather than selecting another 12.1-inch SVGA panel solely based on resolution.

Brightness and Contrast

The LQ121S1LW01 has a typical luminance of 250 cd/m² and a typical contrast ratio of 800:1. These specifications describe the panel's light output and its ability to distinguish between darker and brighter portions of an image.

The panel provides a typical viewing angle of 85° to the left, right, upward, and downward under the CR ≥ 10 condition. Its viewing direction is specified as symmetrical.

The wide viewing characteristics can be useful in equipment where the operator may view the display from different positions. The actual viewing performance can also depend on the controller, display settings, ambient lighting, and installation angle.

Interface and Connector

The Sharp LQ121S1LW01 uses a single-channel, 6-bit LVDS interface through a 20-pin connector. The panel supports a typical LCD supply voltage of 3.3V or 5.0V.

The LVDS interface is used for transmitting the digital display data between the equipment controller and the LCD module. The exact connector pinout, signal assignment, power connections, and timing requirements should be verified against the applicable technical documentation before installation.

A 20-pin connector alone does not guarantee compatibility. Another LCD with a 20-pin connector may have a different LVDS pinout, voltage arrangement, signal mapping, or timing configuration.

Before connecting the panel, verify:

• Exact connector pinout
• LVDS channel configuration
• 6-bit signal configuration
• LVDS signal mapping
• LCD supply voltage
• Connector orientation
• Display timing
• Controller compatibility

Backlight

The LQ121S1LW01 uses a dual-CCFL backlight system with two lamps. The specified backlight life is at least 50,000 hours. The panel does not incorporate the external DC-to-AC inverter required to drive the CCFL lamps.

The technical references specify a typical lamp voltage of approximately 583V and a typical lamp current of 6.0 mA, with minimum and maximum current values also specified.

The existing inverter should therefore be checked carefully when using the LQ121S1LW01 as a replacement. An LED-backlit LCD should not be assumed to be a direct replacement for this CCFL-based panel simply because it has the same screen size and resolution.

Mechanical Dimensions

The LQ121S1LW01 has an active display area of 246.0 × 184.5 mm and a bezel area of approximately 249.0 × 187.5 mm. The maximum outline dimensions are 276.0 × 209.0 × 11.0 mm, with a maximum specified mass of 800 g.

The panel uses face-mounting provisions on the left and right bezel areas. Available technical references identify mounting holes of 2-Φ3.4 and 2-R1.7 on the respective bezel areas.

These dimensions are important when replacing an LCD inside an existing enclosure. Width, height, depth, mounting holes, connector location, cable routing, and available clearance should all be compared with the original display.

Two 12.1-inch 800 × 600 panels can have the same resolution and similar active areas while differing in mounting arrangement or overall dimensions.

Operating Temperature

The LQ121S1LW01 is specified for an operating temperature range of 0°C to 50°C and a storage temperature range of -25°C to 60°C.

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

For installations operating near the specified limits, the complete display assembly and surrounding electronics should be evaluated according to their individual environmental specifications.

Industrial Applications

The Sharp LQ121S1LW01 was developed as an industrial-oriented LCD module and can be relevant to equipment requiring a 12.1-inch SVGA display with LVDS connectivity and a dual-CCFL backlight. Sharp also identified industrial, gaming, medical, and electronic signage applications for this generation of display technology.

Potential applications include:

• Industrial PCs
• HMI systems
• Industrial control panels
• CNC machine interfaces
• Factory automation equipment
• Machine monitoring systems
• Process control equipment
• Medical equipment
• Medical monitoring systems
• Measuring instruments
• Industrial instrumentation
• Embedded computing systems
• Operator interface terminals
• Electronic signage equipment
• Legacy industrial machinery

The actual suitability depends on the electrical, mechanical, environmental, controller, and backlight requirements of the target equipment.

Compatibility and Replacement Note

The Sharp LQ121S1LW01 should be selected as a replacement only after comparing its complete specifications with the original LCD.

Before purchasing or installing the panel, verify:

• Exact original LCD model and suffix
• 12.1-inch screen size
• 800 × 600 resolution
• Active display area
• Bezel dimensions
• Overall dimensions
• Panel thickness
• Mounting holes and mounting arrangement
• Connector type and location
• 20-pin connector configuration
• Complete LVDS pinout
• Single-channel LVDS configuration
• 6-bit signal configuration
• Display timing requirements
• 3.3V or 5.0V supply requirement
• CCFL backlight configuration
• CCFL inverter requirements
• Lamp voltage and current requirements
• Controller compatibility
• Operating temperature requirements
• Mechanical clearance

A similar 12.1-inch size, 800 × 600 resolution, or 20-pin connector does not automatically mean another LCD is a direct replacement.

Connector type alone is not sufficient to establish compatibility. The exact model and suffix, active area, dimensions, mounting, LVDS pinout, voltage, timing, backlight system, inverter, and controller compatibility should all be verified.

The LQ121S1LW01 is specifically documented as a 1-channel, 6-bit LVDS module with a 20-pin connector and 3.3V/5.0V typical supply. These characteristics should be matched against the original equipment before connecting the replacement.

For legacy equipment, compare the model number printed on the original LCD with LQ121S1LW01 and verify the complete technical specifications before ordering.
