LANMU 1.3" SSH1106 SPI I2C IIC 128X64 OLED LCD LED Display Module Board For Arduino UNO R3 STM OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. A simplified manufacturing process compared to TFT-LCD (See comparison of Picture 1 and Picture 2 below) Self-emitting light, in contrast to the required backlight for TFT-LCD High luminosity. Lightweight and thin
