OLED is an organic light-emitting diode, also known as organic dot laser display. Composed of a very thin coating of organic materials that emit light and a glass substrate, it has self-luminous properties, a large viewing angle and low power consumption.
It doesn’t need a backlight ( it will light up when the driver and wiring up are correct).
It has high contrast and fast response speed, applied for flexible surface. In addition, it is easy to build.
The module comes with 4 positioning holes, which is convenient for you to fix it on other devices.
