Product Introduction
The AUO G121SN01 V4 is a high-performance 12.1-inch industrial-grade LCD module from AU Optronics. As a mature evolution of the G121SN01 series, the V4 version maintains the classic 4:3 aspect ratio and 800x600 resolution while further optimizing the stability and color reproduction of the backlight system.
The most significant feature of this model is its integrated built-in LED driver circuit, greatly simplifying system integration and eliminating the need for an additional boost converter. Its operating temperature range of -30°C to 85°C makes it suitable for a wide range of heavy industrial, military, and aerospace applications, from frigid polar regions to scorching deserts.
