Product Description:

		The CH400OL001A is a high-performance 4 inch AMOLED display module (specifically 3.92") designed to serve as a space-saving display solution for advanced Human-Machine Interface (HMI) control panels. With a native 1080x1240 resolution, this module offers an incredible pixel density, ensuring that complex industrial icons, detailed status charts, and high-definition UI elements are rendered with absolute precision.
		As an Active Matrix OLED panel, it provides self-emissive technology that guarantees deep blacks and a high contrast ratio, crucial for legibility in various lighting conditions found in smart home and industrial environments. The module is integrated with the CH*** driver IC and FT*** touch IC, facilitating responsive and intuitive touch interactions . For hardware engineers, the MIPI 4-lane interface allows for high-speed data throughput, supporting fluid animations and real-time data updates without the bulk of traditional parallel interfaces .

Features:

• Superior 1080x1240 HD Clarity: Provides high-definition visualization for intricate control interfaces and detailed data monitoring.
• Responsive FT*** Capacitive Touch: Features a high-sensitivity touch panel for reliable and smooth multi-touch HMI operation .
• Ultra-Slim 1.2mm Profile: One of the thinnest 4 inch AMOLED display modules in its class, ideal for compact and portable hardware design.
• Wide "Free" Viewing Angle: AMOLED technology ensures consistent visual performance from all angles, critical for wall-mounted or desktop control panels.
