Electronic paper, e-paper and electronic ink are display technologies which are designed to mimic the appearance of ordinary ink on paper. Unlike conventional backlit flat panel displays which emit light, electronic paper displays reflect light like ordinary paper, theoretically making it more comfortable to read, and giving the surface a wider viewing angle compared to conventional displays. In this tutorial, we will introduce an E-paper shield. This E-paper shield can be programmed using pcDuino or Arduino.
E-paper is risen in recent years which is a kind of replacement of traditional paper books, the way to achieve the e-paper technology including cholesterol liquid crystal display technology, electrophoretic display technology( EPD) and electrowetting display technology. Support E-paper display is electronic ink, electronic ink is actually a new material, it is the product of chemistry, physics and electronics multidisciplinary development, this material can be printed onto any material surface and to display the text or image information. Next, we will demo how to display the image with the Arduino and E-paper.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Part List
1 x Arduino Uno
1 x E-paper
Step 2: Run and Test
Use Image2Lcd to deal with the image which will be progressed on E-paper( size 320 x 240), save to .c file:
2. Copy the data in the .c file to the code correspond location.
3. Unload the code to Arduino Uno, open the serial port, input the 1,2,3,4 to the data send box.
Wait for a moment, and you will see the e-paper display the final show picture.
