E-Paper display module TYKEGM042001T09

TFTcapacitive touch screendot-matrix

Product Overview
The 4.2-inch e-paper display module TYKEGM042001T09 integrates a 400×300 high-resolution E-Ink panel with a built-in front light and an optional capacitive touch panel. Designed for extremely low power consumption and long-term content retention, it delivers paper-like readability in direct sunlight and low-light conditions. Suitable for industrial, medical and IoT applications requiring clear visuals, user interaction and energy efficiency.

Features

• Display Size: 4.2 inches
• Resolution: 400 (H) × 300 (V) dot matrix (119 DPI)
• Touch: Capacitive touch panel (resistive optional)
• Front Light: Integrated for low-light visibility
• Low Power: Consumes power only during screen updates
• Interfaces: SPI common; I2C or higher-speed interfaces available

Benefits

• Battery-friendly operation—energy used primarily on refresh
• High readability—E-Ink contrast with front illumination for any lighting
• Intuitive control—capacitive touch support for user interaction
• Stable image retention—content remains without continuous power
• Compact and lightweight—suitable for portable or handheld devices
• Flexible integration—fits medical devices, industrial tools, smart tags, e-readers and IoT systems
