Overview 

• Due to the advantages of ultra-low power consumption, wide viewing angle, and clear display without electricity, it is an ideal choice for applications such as shelf labels and industrial instruments. This is a 2.13-inch DES electronic paper display with a resolution of 212x104 and can communicate through the SPI interface.
• The driver IC includes gate buffer, source buffer, time control logic, oscillator, DC-DC, SRAM, LUT, VCOM, and each panel provides a frame. Wide operating temperature range: -20℃ ~ 60℃.
• Can be used in cold environment and sunlight, GDEW0213M21 is an excellent choice for shelf label, smart label, smart home application, industrial tool, smart card, outdoor equipment application.
• Power consumption: ultra-low power consumption
• Viewing angle: 180 degrees
• Use in the sun: support
• Ultra-wide temperature -20 degrees use: support 

Features

• No backlight, even if it is turned off, the last content can be displayed for a long time
• Ultra-low power consumption, basically only need to refresh the power supply
• Comes with development resources and manuals (example of Arduin-MCU32)
• Manufactured using new technology: DES, DES has the following characteristics: Compared with other similar products, DES has higher contrast and better display effect. (DES products are greater than 1:45, ordinary EPD products are less than 1:25)
• Ultra-wide temperature working range: -20℃ ~ 60℃ (conventional monochromatic electronic ink screen working temperature range: 0℃-50℃, three-color working temperature 0℃-40℃, ultra-low temperature working temperature: -25℃ ~ 25℃)
• It can be used in the sun and cold environment.
