Description
WEO001602H is a16 Character x 2 lines COG OLED display module. This 16x2 OLED display is built-in with WS0012 IC; it supports 6800/8080 8-bit parallel and I2C, 4-wire SPI interface, the supply voltage for logic is 3.3V (VDD), and the supply voltage for display is 8.5V(VCC). The current with 50% checkerboard display is 2mA @ VCC 8.5V (for white color), 1/16 driving duty. WEO001602H OLED module can be operating at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃.
We suggest customers consider using this low-power 16x2 character OLED to upgrade the existing STN character display. Below are the advantages of this OLED display.
►Faster response time "At +25 ℃ 10 μsec
►Unlimited viewing angle "Up to 175 degree
►Thin – No need of backlight, self-emitting
►High Brightness
►High contrast ratio 10,000:1
►Wide Operation Temperature
►Lower power consumption
