Feature:1. Working Principle: The working principle is charged nanoparticles suspended in the liquid are subjected to the action of the electric field to migrate, and reflect under the ambient light to form a display effect close to that of traditional printing paper.2. Viewing Angle: The electronic ink screen can clearly display the picture under ambient light such as lighting, natural light, etc., without backlight, and the viewing angle is almost 180°. Because of its display effect comparable to traditional paper, it is often used in applications such as readers.3. Microcapsule Electrophoresis Display: The epaper display uses microcapsule electrophoresis display technology for image display.4. Multi Mode Selection: E paper display supports multi mode selection. Through the mode switch button, users can freely switch between GC16, A2 and A2+ three modes.5. Speed Adjustment: Electronic ink screen supports 10 contrast adjustments and 5 display speed adjustments. With the mode selection, users can match their own display effects.Specification:Item Type: E Paper DisplayMaterial: LCD, PCBSize: 7.8inGray Level: 2-16 Levels (1-4 Bits)Display Panel: Electronic Ink ScreenDisplay Interface: High Definition Multimedia InterfaceResolution: 1872x1404 (300DPI)Display Color: Black, WhiteViewing Angle: ＞170°Display Adjustment: Mode/ContrastSupport Equipment: For , for , PCSize: Approx. 127.6mm / 5.0in, Approx. 158.184mm / 6.2in, Approx. 173.8mm / 6.8in, Approx. 118.638mm / 4.7in, Approx. 81.05mm / 3.2in, Approx. 73.61mm / 2.9in, Approx. 42.30mm / 1.7in, Approx. 15.30mm / 0.6inPackage List:1 x Electronic Ink Screen1 x High Definition Multimedia Interface Cable1 x Mini High Definition Multimedia Interface Adapter1 x Type-C Data Cable1 x Riser CardNote:1. Due to the limitation of the display principle, the electronic ink screen display has a low freshen rate (about 15Hz in A2 mode), which is suitable for
