OLED (Organic Light-Emitting Diode) means that the screen consists of all small RGB LEDs (each pixel equals 1 RGB LED). As a result, the display does not need a backlight and is much more economical in use. In addition, this gives a much higher contrast, making this display very clear and readable despite its size. This display contains 96 x 64 (6144) RGB LEDs on an area of 20mm x 14mm.
