Technical Specifications

The specifications above are based on the supplied product information and supporting technical references for the KCS057QV1AJ-G23.

5.7-Inch QVGA Color LCD Display

The Kyocera KCS057QV1AJ-G23 features a 5.7-inch screen with a 320 × 240 QVGA resolution and a 4:3 aspect ratio. Its active display area measures approximately 115.2 × 86.4 mm, making it suitable for compact industrial and embedded equipment.

The QVGA resolution provides sufficient display space for equipment status, measurement values, menus, graphical controls, monitoring information, and other visual content commonly used in embedded systems.

CSTN Normally Black Display Technology

The KCS057QV1AJ-G23 uses CSTN technology with an STN normally black, transmissive display mode. It supports color reproduction with approximately 35% NTSC coverage.

Its typical viewing angles are approximately 50° left, 50° right, 30° upward, and 30° downward at CR≥2. The installation orientation should therefore be considered when integrating the module into equipment.

200 cd/m² Brightness and 40:1 Contrast

The panel provides a typical luminance of 200 cd/m² and a 40:1 contrast ratio. These specifications are suited to applications focused on displaying equipment information, measurement values, menus, status indicators, and basic graphical interfaces.

The glossy surface treatment has a listed haze value of 0%, which preserves the characteristics of the panel's original display surface.

8-Bit Parallel Interface

The KCS057QV1AJ-G23 uses an 8-bit parallel data interface through a 15-pin connector. The module operates at a specified 75 Hz frame rate and uses a typical 5.0V input voltage.

For replacement applications, the host controller's interface configuration, pin assignment, timing requirements, and electrical specifications should be verified before installation.

CCFL Backlight

The display uses one CCFL lamp for backlighting, with an approximately 40,000-hour lamp life. Available specifications indicate that the backlight driver is optional.

Since CCFL lighting requires appropriate driving circuitry, the backlight connection should be checked carefully when replacing an existing display or integrating the panel into a new system.

Compact 9 mm Module Design

The KCS057QV1AJ-G23 has overall dimensions of approximately 154.6 × 114.8 × 9 mm, with an active display area of 115.2 × 86.4 mm.

Its compact dimensions make it suitable for embedded controllers, industrial instruments, equipment control panels, monitoring devices, and other applications with limited installation space.

Operating Temperature Range

The KCS057QV1AJ-G23 supports an operating temperature range of 0°C to 60°C and a storage temperature range of -20°C to 60°C.

The display should be operated within the specified environmental limits to maintain expected optical and electrical performance.
