Understanding TFT LCD EPD: Definition and Technical Specifications

TFT LCD EPD refers to two distinct yet complementary display technologies often evaluated together for industrial and consumer applications. A TFT LCD uses thin-film transistors to control individual pixels, delivering vibrant colors, fast refresh rates, and high brightness. In contrast, EPD (Electrophoretic Display), commonly known as e-paper, mimics the appearance of ink on paper, offering ultra-low power consumption and excellent sunlight readability.

Key technical specifications for TFT LCD modules typically include:

• Resolution: From 320x240 (QVGA) to 1920x1080 (Full HD) and beyond
• Brightness: 250 to 1000 nits, depending on application
• Viewing Angle: 80/80/80/80 degrees for IPS panels
• Interface: RGB, LVDS, MIPI, or eDP
• Operating Temperature: -20°C to +70°C for standard models

For EPD modules, critical parameters include:

• Resolution: Typically lower than TFT, ranging from 128x64 to 1872x1404
• Reflectivity: 30% to 45% for paper-like readability
• Update Time: 300ms to 1s depending on grayscale depth
• Power Consumption: Near zero during static image display
• Bistability: Image retention without power

International standards governing these technologies include IEC 62368-1 for safety, RoHS for hazardous substance restriction, and REACH for chemical compliance. For TFT LCDs, the ISO 9241-305 standard addresses ergonomic display quality. EPD modules often follow ASTM F2150 for electronic paper performance testing.
