G121XCE-L02 Display Technology
To achieve stable and clear image performance, the G121XCE-L02 LCD adopts mature TFT-LCD display technology, combined with an efficient backlight system and a reliable signal transmission interface. Through the coordinated operation of an active matrix structure, WLED backlight, and an LVDS data interface, this display module is able to deliver stable and efficient visual performance.
1. TFT Active Matrix Structure
The G121XCE-L02 uses a TFT (Thin Film Transistor) active matrix structure. In this architecture, each pixel is controlled by an independent thin-film transistor, enabling precise regulation of the liquid crystal molecules and ensuring accurate image control.
Each pixel on the panel is composed of Red, Green, and Blue (RGB) sub-pixels, arranged in a vertical stripe pattern. By independently adjusting the brightness of each sub-pixel, the display can produce rich color levels and deliver high-quality image performance.
2. Backlight System
This module uses a WLED (White LED) backlight system as its light source, providing uniform and stable illumination for the LCD panel. Compared with traditional backlight solutions, WLED technology offers higher brightness efficiency and lower power consumption.
In addition, the LED backlight system provides excellent brightness stability and a long service life. It can maintain consistent display performance during long-term operation while helping reduce overall system power consumption, meeting the reliability and energy-efficiency requirements of industrial equipment.
3. Interface and Signal Transmission
The G121XCE-L02 adopts an LVDS (Low Voltage Differential Signaling) interface for data transmission. LVDS technology uses differential signaling to transmit data, which helps reduce electromagnetic interference while enabling high-speed and stable signal transmission with low power consumption.
Signal Interface of G121XCE-L02
The Innolux G121XCE-L02 features a standard LVDS (1 ch, 8-bit) signal interface, facilitating data exchange through a precision 20-pin connector. This single-channel 8-bit design not only provides a rich color depth of up to 16.7M colors for smooth gradients but also features exceptional resistance to electromagnetic interference (EMI).
For system integrators, the compact 20-pin configuration simplifies wiring complexity, allowing for seamless compatibility with a wide range of mainstream industrial controller boards.
