Technical Specifications

The specifications are based on the available LG.Philips documentation and supporting technical references.

10.4-Inch VGA Industrial Display

The LG.Philips LB104V03-A1 features a 10.4-inch display with a 640 × 480 VGA resolution and a 4:3 aspect ratio. Its active display area measures approximately 211.2 × 158.4 mm, providing a practical viewing area for industrial equipment and embedded systems.

The traditional 4:3 format makes this panel suitable for equipment designed around older VGA-based display systems, particularly where a replacement for an original industrial LCD is required.

400 cd/m² Brightness and 300:1 Contrast

The LB104V03-A1 provides a typical luminance of 400 cd/m² and a 300:1 contrast ratio. These specifications support readable text, graphics, machine parameters, status information, and monitoring interfaces.

The panel supports 262K colors and approximately 45% NTSC color coverage.

TN Normally White Display Technology

The panel uses TN, normally white, transmissive TFT-LCD technology. Its typical viewing angles are approximately 60° left, 60° right, 40° upward, and 50° downward at CR≥10. The specified viewing direction is 6 o'clock.

This makes the panel particularly appropriate for fixed-position industrial equipment where the operator views the display from a defined location.

Antiglare Surface with 3H Hard Coating

The LB104V03-A1 features an antiglare surface with a 3H hard coating. The antiglare treatment helps reduce reflections from ambient lighting, while the hard coating offers additional protection against surface scratches during handling and regular use.

This is useful for industrial control panels and equipment installed in environments with varying ambient light.

Parallel RGB Interface with 30-Pin Connector

The LB104V03-A1 uses a 1-channel, 6-bit Parallel RGB interface through a 30-pin connector. The typical LCD supply voltage is 3.3V, with a refresh rate of 60 Hz.

For replacement applications, the connector type alone should not be used to establish compatibility. The complete pin assignment, RGB configuration, signal timing, supply voltage, and host controller specifications should be verified before installation.

Dual CCFL Backlight

The LB104V03-A1 uses two CCFL lamps for backlighting. The specified backlight life is approximately 40,000 hours, and the module does not include the backlight driver.

Because CCFL lamps require suitable high-voltage driving circuitry, the existing inverter or a compatible external CCFL driver must be checked before connecting the panel.

Compact 10.5 mm Panel Design

The module has overall dimensions of approximately 236 × 180 × 10.5 mm, while the active display area measures 211.2 × 158.4 mm. The maximum module weight is approximately 490 g.

These dimensions make the panel suitable for compact industrial equipment, embedded systems, control panels, and replacement applications where enclosure space is limited.

Operating Temperature Range

The LB104V03-A1 is specified for an operating temperature range of 0°C to 50°C and a storage temperature range of -20°C to 60°C.

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