200x200, 1.54inch E-Ink display raw panel without driver board.
1.54inch e-Paper Module (B)

200x200, 1.54inch E-Ink display module, three-color, SPI interface
{{{name3}}}

{{{name4}}}

{{{name5}}}

Introduction

Note: As the raw panel requires a driver board, we recommend you to buy the HAT or buy a driver board for use, or you need to make the driver board by yourself. And this instruction is based on the version with PCB or driver board.

Display a Frame (DisplayFrame)

DisplayFrame is used to send a frame to module, and the screen will refresh and display it.

Process: Send command data start transmission 1 -> Send data of dark area -> Send command data start transmission 2 -> Send data of red area -> Refresh the screen. Note:

  • One frame consist of images of black area and red area, so we need to send two images for displaying one frame,
  • The image of black part: 2 bits = 1 pixel, doesn’t support Gray scale (Can only display black and white). 00b stand for black pixel, and 11b stand for white.

For example:

0xC3:4 pixels □■■□
0x00:4 pixels ■■■■
0xFF:4 pixels □□□□
0x66:The state of pixels is uncertain
  • The image of red area: 1 bit = 1 pixel, doesn’t support Gray scale (Can only display red and white). The pixel is white if Bit is set, and it is red on the contrary.

For example:

0xC3:8 pixels □□■■■■□□
0x00:8 pixels ■■■■■■■■
0xFF:8 pixels □□□□□□□□
0x66:8 pixels ■□□■■□□■
  • This module doesn’t support partial refresh.
  • The refresh rate of this module is slow, and it will flicker for several times during refreshing (about 8s). Please be patient.

FAQ

 Answer:
  • Two-color B/W e-paper
    • 【Working】Temperature: 0~50°C; Humidity: 35%~65%RH
    • 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 6 months
    • 【Transport】Temperature: -25~70°C; Max transport time: 10 days
    • 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h
  • Three-Color e-Paper
    • 【Working】Temperature: 0~40°C; Humidity: 35%~65%RH
    • 【Storage】Temperature: ≤30°C; Humidity: ≤55%RH; Max storage time: 3 months
    • 【Transport】Temperature: -25~60°C; Max transport time: 10 days
    • 【Unpack】Temperature: 20°C±5°C; Humidity: 50%RH±5%RH; Max storage time: Should be assembled in 72h

When store three-color e-Paper, please refresh it to white, and keep the screen upward. Note that you need to update it at least every three months.
