High Resolution 3.92" AMOLED Touchscreen Module for Handheld Medical Devices

Product Description:

The CH400OL001A is a professional-grade 3.92 inch AMOLED touchscreen module specifically designed to meet the rigorous imaging requirements of modern handheld medical devices and high-end industrial instruments. With a native resolution of 1080x1240, this display offers an exceptional pixel density that ensures crystal-clear visualization of complex data and high-resolution medical imagery.

At the core of its interactive capability is the FT*** touch IC, which provides precise capacitive touch control, essential for critical diagnostic equipment. The module utilizes Active Matrix OLED technology, delivering deep blacks and a high contrast ratio that traditional LCDs cannot match. Engineers will appreciate the space-saving display solution provided by its ultra-thin profile—measuring only 1.2mm in maximum thickness—allowing for more compact and ergonomic device designs.

The integration of a MIPI interface ensures high-speed data throughput while maintaining the low power consumption necessary for portable, battery-operated devices. Furthermore, the free viewing angle characteristic of AMOLED technology ensures that critical information remains legible from any position, enhancing usability in fast-paced clinical environments. Manufactured under strict quality protocols, the module is fully RoHS compliant and operates reliably within a temperature range of -10°C to +60°C.
