4 Inch AMOLED Screen 1080x1240 Resolution For Advanced HMI Control Panels

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 .

Measuring a maximum thickness of only 1.2mm, the CH400OL001A is engineered for sleek, modern device profiles where internal space is at a premium. Its free viewing angle ensures that operators can monitor the display from any perspective without color inversion or brightness loss. Designed for longevity and performance, this RoHS compliant module operates reliably within a temperature range of -10°C to +60°C, making it a robust choice for sophisticated control systems .

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.
