Technical Specifications

10.4 Inch 640 × 480 VGA Display

The Sharp LQ10D368 provides a 10.4-inch diagonal display with a 640 × 480 VGA resolution. Its 4:3 format and 211.2 × 158.4 mm active area are characteristic of the 10.4-inch VGA LCD modules widely used in earlier generations of industrial and embedded equipment.

The 640 × 480 resolution is suitable for displaying machine parameters, numerical readings, menus, status information, control interfaces, measurement values, and basic graphical information.

The panel has an approximate pixel density of 76 PPI. For replacement applications, however, screen size and resolution should only be considered part of the compatibility assessment. Active area, outline dimensions, mounting arrangement, connector, pinout, interface, voltage, backlight, and controller requirements must also match the target equipment.

Display Technology

The LQ10D368 uses amorphous silicon TFT-LCD technology with a TN, Normally White, Transmissive display mode. TFT technology allows the panel to control individual pixels for displaying text, graphics, images, and equipment status information.

The TN display configuration has viewing characteristics that differ from newer IPS and other LCD technologies. This can be important when replacing a legacy industrial panel where the original viewing direction and optical behavior are part of the equipment design.

The panel supports 262K colors and uses an RGB vertical stripe pixel arrangement.

Brightness and Contrast

The Sharp LQ10D368 has a typical luminance of 200 cd/m² and a typical contrast ratio of 300:1. These specifications describe the panel's light output and its ability to distinguish between darker and brighter image areas.

The specified viewing angles are 70° to the left, 70° to the right, 40° upward, and 70° downward under the CR ≥ 10 measurement condition. These viewing characteristics should be considered when the LCD is installed in equipment where the operator views the display from a fixed position.

The front surface has antiglare treatment and a 3H hard coating. This surface treatment can help reduce reflected light and provides a degree of surface protection during normal handling.

Interface and Connector

The LQ10D368 uses a Parallel RGB interface with a 1-channel, 6-bit signal configuration and a 31-pin connector. This corresponds to an 18-bit RGB signal configuration, with 6 bits assigned to each RGB color channel.

The revised Sharp specification identifies a VCC range supporting 3.3V and 5.0V operation, with the nominal supply depending on the system configuration. The original specification revision specifically documents the change from a 5.0V-only supply specification to a 3.3V/5.0V supply arrangement.

A 31-pin connector does not automatically make another 31-pin LCD compatible. The complete pinout, RGB signal assignment, timing signals, supply voltage, connector orientation, and controller electronics should be compared before installation.

This is especially important when replacing legacy LCDs because panels with the same connector count can have different electrical configurations.

Backlight

The Sharp LQ10D368 uses a single CCFL backlight with a specified life of 50,000 hours. The module requires appropriate external circuitry for driving the CCFL backlight.

The backlight system should be treated separately from the LCD signal interface when checking compatibility. The existing equipment's CCFL inverter or backlight driver should be verified for the required electrical characteristics before installation.

An LED-backlit panel should not be assumed to be a direct replacement for the LQ10D368 simply because it has the same screen size and resolution.

Mechanical Dimensions

The Sharp LQ10D368 has an active area of 211.2 × 158.4 mm. The original Sharp specification lists an outline dimension of 246.5 × 179.4 mm with a maximum depth of 11.5 mm. The specified maximum mass is 520 g.

Some secondary technical references list a nominal thickness around 10.5 to 11 mm, while the revised Sharp specification identifies 11.5 mm as the maximum dimension. For mechanical replacement work, the applicable original specification should be used when checking available enclosure clearance.

Before installing a replacement, compare the original LCD's active area, overall width and height, thickness, mounting locations, connector position, and cable clearance. Two 10.4-inch VGA LCDs can have different mechanical dimensions and may not be physically interchangeable.

Operating Temperature

The Sharp LQ10D368 is specified for an operating temperature range of -10°C to 65°C and a storage temperature range of -30°C to 70°C. These values are documented in the Sharp specification revision.

The temperature rating should be considered for the complete installation. The LCD controller, CCFL inverter, cables, enclosure, and other electronics may have different environmental limits.

For equipment operating near the upper or lower temperature limits, the applicable specifications of the complete display assembly should be checked before deployment.

Industrial Applications

The LQ10D368 is a legacy 10.4-inch VGA TFT-LCD module suited to equipment using compatible Parallel RGB display electronics and CCFL backlight circuitry.

Potential applications include:

·        Industrial PCs

·        HMI systems

·        CNC machine interfaces

·        Industrial automation equipment

·        Machine control panels

·        Process monitoring systems

·        Instrumentation equipment

·        Medical equipment

·        Industrial monitoring equipment

·        Embedded control systems

·        Factory automation equipment

·        Legacy industrial machinery

·        Equipment requiring replacement of an original 10.4-inch VGA LCD

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

Compatibility and Replacement Note

The Sharp LQ10D368 is an older LCD module and should be selected for replacement only after comparing its complete specifications with the original display.

Before purchasing or installing the panel, verify:

·        Exact original LCD model and suffix

·        10.4-inch screen size

·        640 × 480 resolution

·        Active display area

·        Overall dimensions

·        Panel thickness

·        Mounting holes and mounting arrangement

·        Connector type and position

·        31-pin connector configuration

·        Complete connector pinout

·        Parallel RGB interface

·        1-channel, 6-bit signal configuration

·        LCD supply voltage

·        Display timing requirements

·        CCFL backlight configuration

·        Backlight inverter or driver requirements

·        Controller compatibility

·        Operating temperature requirements

·        Mechanical clearance inside the equipment

A similar screen size, VGA resolution, or connector count does not automatically mean that another LCD is a direct replacement.

Connector type alone is not sufficient to establish compatibility. The model number, pinout, interface, voltage, mounting dimensions, backlight system, timing, and controller requirements should all be verified.

The LQ10D368 is listed as obsolete by DigiKey, which means it is no longer manufactured as a current product. This makes exact model verification particularly important when sourcing a replacement for legacy equipment.

For replacement applications, compare the model number printed on the original panel with LQ10D368 and verify the complete technical specifications before ordering.
