Welcome to our shop! This is a 1.3 inch OLED display module with a resolution of 128x64. It features an emissive electroluminescent layer that emits light in response to an electric current. The OLED display module works without a backlight and can give out light by itself. In low ambient light conditions, such as a dark room, the OLED screen can achieve a higher contrast ratio compared to an LCD. Additionally, OLEDs have a much faster response time than LCDs.
