G150XGE-L04 Pin Configuration
This module adopts an LVDS (1-channel, 6-bit/8-bit compatible) signal interface. The display data and logic signals are transmitted through a 20-pin surface-mount connector, with the commonly used matching socket typically being MSB240420-E. When designing the carrier board, it is necessary to select a precisely compatible cable harness and wiring assembly.

Hardware Tips
To avoid signal distortion or hardware damage, PCB engineers must strictly follow the two rules below during layout design:
1. 100Ω Differential Impedance Control
LVDS signals (such as RX0±) are high-speed differential signals, and the trace impedance must be controlled at 100Ω ±10%. Differential pairs must be strictly length-matched (within ±5 mil), via usage should be minimized, and a solid ground reference plane should be provided to reduce reflection and EMI, preventing screen flickering or water ripple effects.
2. Strict Power On/Off Sequence Control
During power-up, VCC (e.g., 3.3V) must be stabilized first, and after meeting the required delay (typically Tt > 0.5 ms), LVDS signals can be enabled. During power-down, LVDS signals must be disabled first before cutting off VCC. Otherwise, the driver IC may enter a latch-up condition, causing excessive current and potential damage to the module.
G150XGE-L04 Block Diagram Analysis
According to the system block diagram, the G150XGE-L04 module completes image display through four main paths: signal decoding, power conversion, row/column driving, and independent backlight control.
First, external LVDS differential signals and clock are transmitted through the 20-pin connector to the LVDS receiver for image decoding. Meanwhile, the input logic voltage VCC is converted by a DC/DC converter into internal reference voltages required by each circuit block.
Next, the decoded timing data is sent to the scan driver IC (row driver) and data driver IC (column driver) to accurately control the 1024 × 768 TFT LCD panel. At the same time, independent backlight power (Vi) is supplied via a 5-pin connector and regulated by the built-in LED converter, providing a stable constant-current drive for the LED backlight unit.
