Advantages of EINK

E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.

Touch control power supply configuration

the touch control power supply is determined by the position of 0R resistor.


0R RESISTOR POSITION     TOUCH CONTROL POWER SUPPLY      DESCRIPTION
A                                          VCC                                                     always powered by VCC (default)
B                                          EN                                                      controlled by user I/O
C                                          VEN                                                    controlled with ePaper (ERST)
NC                                       GND                                                    no power supply for touch control
