Sharp LQ084S3DG01 8.4 Inch TFT LCD Panel

The Sharp LQ084S3DG01 is an 8.4-inch industrial TFT-LCD module designed for equipment that requires a compact SVGA display with a traditional parallel RGB interface. It features a resolution of 800 × 600 pixels and uses a-Si TFT-LCD technology with a TN, normally white, transmissive display mode.

The panel provides a 170.4 × 127.8 mm active display area and a typical luminance of 350 cd/m². Its 320:1 typical contrast ratio and antireflection surface treatment make it suitable for a range of industrial and embedded display applications where clear visual information is required.

The LQ084S3DG01 uses a 30-pin Parallel RGB interface with 1-channel 6-bit configuration and operates from a typical 3.3V LCD supply. The display uses two CCFL backlight tubes with a specified life of 50,000 hours and requires an external backlight driver.

This Sharp LCD module is particularly relevant when replacing an original display in industrial PCs, control equipment, embedded systems, instrumentation, and other legacy equipment designed around the same panel specifications.

Technical Specifications

The technical specifications above are based on the supplied product listing and cross-checked technical references.

8.4 Inch 800 × 600 SVGA Display

The Sharp LQ084S3DG01 features an 8.4-inch display with an 800 × 600 SVGA resolution. This resolution provides 480,000 pixels across the panel, making it suitable for displaying control interfaces, machine parameters, monitoring information, menus, graphs, and other industrial operating data.

The active display area measures 170.4 × 127.8 mm. The combination of the 8.4-inch screen size and 800 × 600 resolution is particularly relevant for older industrial systems that were designed around SVGA-format LCD panels.

When replacing an existing panel, the screen size and resolution should be treated as only part of the compatibility check. The active area, outline dimensions, mounting arrangement, interface, connector, pinout, voltage, and backlight system should also match the original equipment.

Display Technology

The LQ084S3DG01 uses a-Si TFT-LCD technology with a TN, normally white, transmissive display mode. TFT technology provides individually controlled pixels for displaying graphical and textual information, while the transmissive configuration uses the panel's backlight to illuminate the display.

The TN configuration is characteristic of many industrial and legacy TFT panels and should be considered when replacing a panel with a different display technology or viewing-angle specification.

The panel has an antireflection surface treatment, which is intended to reduce reflected light from the display surface.

Brightness and Contrast

The Sharp LQ084S3DG01 has a typical luminance of 350 cd/m² and a typical contrast ratio of 320:1. These specifications describe the panel's brightness and its ability to distinguish between dark and bright image areas.

The viewing angle specification is 80° / 80° / 45° / 80° under the stated contrast-ratio measurement condition. Because the panel uses TN technology, viewing performance can vary depending on the direction from which the display is observed.

The available specifications should be considered when replacing an LCD in equipment where the original viewing characteristics are important.

Interface and Connector

The LQ084S3DG01 uses a Parallel RGB signal interface with a 1-channel, 6-bit configuration and a 30-pin connector. It is specified for a typical 3.3V LCD supply and has a 60 Hz frame rate.

For replacement applications, the connector count or physical appearance alone should not be used to determine compatibility. The complete interface configuration, signal assignment, pinout, voltage requirements, and controller electronics must be checked against the equipment's original LCD.

A panel with the same number of pins may still be electrically incompatible if the pin assignment or signal configuration differs.

Backlight

The Sharp LQ084S3DG01 uses two CCFL tubes for illumination. The specified backlight life is 50,000 hours, and the panel requires an external backlight driver.

This is particularly important when replacing an LCD in older industrial equipment. A replacement installation should account for the original CCFL inverter or backlight driver requirements. The LCD signal connection and the CCFL backlight circuit should be treated as separate compatibility considerations.

Do not connect the backlight directly to a power source unless the required driver specifications and connection method have been confirmed.

Mechanical Dimensions

The LQ084S3DG01 has an active area of 170.4 × 127.8 mm and an outline dimension of approximately 199.5 × 149.5 mm. The listed overall depth is 12.1 mm.

These dimensions are important when the LCD is being used as a replacement in an existing enclosure. Even when two panels have the same 8.4-inch diagonal size, differences in active area, outer dimensions, thickness, mounting points, and bezel arrangement can prevent a direct mechanical replacement.

Measure the existing panel and compare the original manufacturer's specifications before installation.

Operating Temperature

The Sharp LQ084S3DG01 is specified for an operating temperature range of -30°C to 80°C and a storage temperature range of -30°C to 80°C. The available technical references also specify a vibration level of 2.0G (19.6 m/s²).

These specifications make the panel suitable for equipment that operates across a relatively broad temperature range. However, the complete system's environmental requirements should also be considered, including the enclosure, controller, backlight driver, and other connected components.

Industrial Applications

The Sharp LQ084S3DG01 is suited to equipment designed around an 8.4-inch SVGA TFT display and Parallel RGB interface. Its specifications are particularly relevant to industrial and embedded systems using legacy display architectures.

Typical applications can include:

·        Industrial PCs

·        Industrial control systems

·        HMI equipment

·        CNC machine interfaces

·        Industrial automation equipment

·        Machine control panels

·        Process monitoring systems

·        Instrumentation equipment

·        Embedded control systems

·        Factory monitoring equipment

·        Legacy industrial equipment

·        Equipment requiring replacement of an original 8.4-inch SVGA TFT panel

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

Compatibility and Replacement Note

The Sharp LQ084S3DG01 should be considered for replacement only after comparing its specifications with the original LCD installed in the equipment.

Before purchasing or installing the panel, verify the following:

·        Exact LCD model number and suffix

·        8.4-inch screen size

·        800 × 600 resolution

·        Active display area

·        Overall panel dimensions

·        Panel thickness

·        Mounting points and mounting arrangement

·        Connector type and physical location

·        Complete connector pinout

·        Parallel RGB interface configuration

·        Signal channel and bit configuration

·        LCD supply voltage

·        Backlight type

·        CCFL configuration

·        Backlight driver or inverter requirements

·        Operating temperature requirements

·        Controller compatibility

·        Mechanical clearance inside the equipment

A similar screen size, resolution, or connector count does not automatically mean that another LCD is a direct replacement. Connector type alone is not sufficient to establish compatibility.

For legacy equipment, it is recommended to compare the part number printed on the original LCD and, where possible, match the original datasheet or technical documentation before ordering.
