Innolux G121X1-L04 and G121X1-L03

The Innolux G121X1-L04 and G121X1-L03 are both 12.1-inch TFT-LCD panels designed for industrial and automotive applications. Here, we will compare their key specifications and discuss whether they can be used interchangeably.

Key Specifications Comparison

Resolution: Both models offer a resolution of 1024(RGB)×768 (XGA), providing clear and detailed images suitable for a variety of applications.

Brightness:

• G121X1-L04: 500 cd/m²
• G121X1-L03: 600 cd/m²

The G121X1-L03 has higher brightness, making it more suitable for environments with higher ambient light.

Contrast Ratio:

• G121X1-L04: 700:1
• G121X1-L03: 700:1

Both panels have the same contrast ratio, ensuring similar performance in terms of image quality and color depth.

Viewing Angle:

• G121X1-L04: 80/80/70/70 (Typ.)(CR≥10) (Left/Right/Up/Down)
• G121X1-L03: 80/80/70/70 (Typ.)(CR≥10) (Left/Right/Up/Down)

Both models offer the same viewing angles, ensuring consistent image quality from various perspectives.

Response Time:

• G121X1-L04: 8 ms (Typ.)
• G121X1-L03: 5/11 ms (Typ.)(Tr/Td)

The G121X1-L03 has a faster response time, which is beneficial for reducing motion blur in dynamic images.

Light Source:

• G121X1-L04: WLED, 50K hours, With LED Driver
• G121X1-L03: WLED, 50K hours, With LED Driver

Both panels use the same light source technology, ensuring long-lasting and efficient backlighting.

Interface:

• G121X1-L04: LVDS (1 ch, 6-bit), 20 pins Connector
• G121X1-L03: LVDS (1 ch, 6/8-bit), 20 pins Connector

The G121X1-L03 supports both 6-bit and 8-bit interfaces, allowing for more color depth and flexibility in display quality.

Power Supply:

• G121X1-L04: 3.3/5.0V (Typ.)(VCC)
• G121X1-L03: 3.3/5.0V (Typ.)(VCC)

Both models operate at the same voltage, ensuring compatibility with existing systems.

Operating Temperature:

• G121X1-L04: -30 ~ 80 °C
• G121X1-L03: -30 ~ 80 °C

Both panels can operate within the same temperature range, making them suitable for harsh environmental conditions.

Interchangeability

While the Innolux G121X1-L04 and G121X1-L03 share many similar specifications, the differences in brightness, response time, and interface options mean they are not entirely interchangeable. The G121X1-L03’s higher brightness and faster response time make it better suited for high-ambient-light environments and applications requiring faster image transitions. However, for general purposes, they can be used interchangeably if these specific differences do not impact the application significantly.
