Forward voltage for white LED backlight is 3.0~3.6V. Please take care of derating for T >+25C a Attention: Do never drive backlight directly to VDD this may damage backlight immediately The blue display cannot be read without backlight. For direct sunlight we suggest to use the J-type.

Alternative module can be programmes with serial data stream. For that solder link SPI has to be closed. Harware specification for serial operation mode is written down in user manual for SSD1803:
