Sharp LM32019T 5.7 Inch STN LCD Panel

The Sharp LM32019T LCD Panel is a 5.7-inch monochrome STN-LCD module designed for industrial equipment, embedded systems, instrumentation, control panels, monitoring equipment, and legacy display replacement applications. It features a 320 × 240 pixel QVGA resolution with approximately 70 PPI and a traditional 4:3 display format.

The panel uses STN LCD technology with a blue negative, transmissive display mode. It provides a typical luminance of 100 cd/m² and a 6:1 contrast ratio. Its monochrome display configuration makes it suitable for equipment interfaces that primarily require clear text, numerical values, status information, menus, and simple graphics.

The LM32019T uses a 1-channel, 4-bit parallel data interface through a 12-pin FPC connector. It operates from a typical 5.0V supply and uses one CCFL backlight with an approximately 15,000-hour life. The CCFL backlight requires an external driver.

Technical Specifications

The specifications above are based on the supplied product listing and its technical specification data.

5.7-Inch QVGA Monochrome Display

The Sharp LM32019T features a 5.7-inch screen with a 320 × 240 QVGA resolution and approximately 70 PPI pixel density. Its active display area measures approximately 115.17 × 86.37 mm, providing a compact viewing area for industrial and embedded equipment.

The QVGA graphic resolution allows the host system to display text, numerical readings, menus, machine parameters, status information, symbols, and simple graphical elements.

Blue Negative STN Display

The LM32019T uses STN, blue negative, transmissive display technology. Unlike a conventional color TFT panel, it is designed as a monochrome display, making it suitable for applications where information readability and compatibility with an existing display system are more important than full-color reproduction.

The display has typical viewing angles of 40° left, 40° right, 25° downward, and 40° upward at CR≥2. The viewing direction should therefore be considered when installing the panel into equipment.

100 cd/m² Brightness and 6:1 Contrast

The LM32019T provides a typical luminance of 100 cd/m² and a 6:1 contrast ratio. These specifications are appropriate for equipment interfaces displaying static or slowly changing information such as machine readings, menus, diagnostics, and system status.

The panel has a typical response time of 190 ms rise and 210 ms fall, making it better suited to static and slow-refresh industrial content than applications requiring fast-moving graphics.

4-Bit Parallel Interface

The Sharp LM32019T uses a 1-channel, 4-bit parallel data interface through a 12-pin FPC connector. This interface configuration is suitable for embedded systems designed around compatible parallel LCD controllers.

For replacement applications, the connector type alone should not be considered sufficient to establish compatibility. The complete pin assignment, interface timing, power requirements, and host controller configuration should be verified before installation.

CCFL Backlight

The LM32019T uses one CCFL backlight with a specified life of approximately 15,000 hours. The backlight driver is not included with the display module.

Because CCFL backlights require appropriate high-voltage driving circuitry, the existing inverter or a compatible external CCFL driver should be checked before installation.

Compact 7.5 mm Design

The LM32019T has overall dimensions of approximately 166 × 109 × 7.5 mm, with an active display area of approximately 115.17 × 86.37 mm.

Its compact form factor makes it suitable for equipment where the available installation space is limited and where a specific 5.7-inch display format is required.

Operating Temperature Range

The Sharp LM32019T is specified for an operating temperature range of 0°C to 45°C and a storage temperature range of -25°C to 60°C.

The panel should be operated within the specified environmental range to maintain expected display performance.

Industrial and Embedded Applications

The Sharp LM32019T can be used in equipment requiring a 5.7-inch monochrome QVGA STN display with a 4-bit parallel interface.

Typical applications include:

·        Industrial control panels

·        HMI systems

·        Machine control equipment

·        Industrial automation

·        Instrumentation

·        Measurement equipment

·        Embedded systems

·        Process monitoring systems

·        Factory equipment

·        Control terminals

·        Electronic instruments

·        Diagnostic equipment

·        Equipment status displays

·        OEM equipment

·        Legacy equipment refurbishment

·        LCD replacement applications

Its compact size, monochrome format, and parallel interface make it particularly relevant for embedded and legacy systems requiring a compatible replacement display.

Compatibility and Replacement Note

The Sharp LM32019T is a specialized STN display, so compatibility should be verified carefully before installation.

Compare the existing display against:

·        Exact model number

·        Resolution

·        Active display area

·        Overall dimensions

·        Mounting arrangement

·        12-pin FPC connector

·        Connector pin assignment

·        4-bit parallel interface

·        LCD supply voltage

·        CCFL backlight configuration

·        External CCFL driver requirements

·        Operating temperature

·        Display orientation

A 5.7-inch 320 × 240 LCD is not automatically a direct replacement for the LM32019T. The electrical interface, connector pinout, backlight configuration, mechanical dimensions, and power requirements should all be verified.
