240x160 LCD Module 3.24-inch COG+PCB - RX240160A - Raystar

240x160 LCD 3.24-inch COG+PCB Graphic Display Module (ST7529 IC)

Model No. RX240160A

The RX240160A is a 3.24-inch 240x160 LCD module featuring the ST7529 controller IC and an 80-series parallel interface for efficient data communication. This 240x160 LCD display adopts a COG+PCB (Chip-on-Glass plus PCB) structure that provides enhanced mechanical strength and simplifies integration for developers. The additional PCB helps users save time by eliminating the need to design their own driver board, enabling faster development and reducing engineering effort.

Operating within a temperature range of -20°C to +70°C, the RX240160A 240x160 LCD ensures stable performance across various environments. The LED backlight delivers consistent brightness, while the module’s low power consumption (typically 4.8 mA at 3.3 V) makes it ideal for portable and battery-powered devices.
