Welcome to our shop! This is a 1.3 inch OLED display module with a resolution of 128x64. It features an emissive electroluminescent layer made of organic compound that emits light in response to an electric current. The 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. The small dimension of this display makes it suitable for MP3 players, function cellphones, smart health devices, and more.
