Product Description

OLED 2864 display module can work without backlight. In a dark environment, contrast of OLED display is higher compared to that of LCD display, and OLED is thinner and lighter. OLED 2864 is a monochrome graphic display module with built-in 0.96 inch, 128X64 high-resolution display. Driver chip of OLED module is SSD1306, which is compatible with IIC or SPI communication interface greatly reducing the IO port occupation. OLED module can be used in various commercial applications, such as display of mobile phones, portable digital media players, radio and digital cameras, and so on.
