OLED modules
These are displays that uses an electroluminescent layer created from an organic semiconductor to emit light. It is positioned between two electrodes, with one electrode being transparent. The advantage of this display type is that it does not require backlighting as it emits visible light. It features a wide viewing angle, high contrast ratio, and "true" black, as the inactive pixels are completely turned off. The construction advantages of this display type allow for its implementation in transparent or flexible versions, making it suitable for portable and miniature devices.
This type of display is widely used in smartphones, televisions, monitors, smartwatches, and similar devices.
SOS electronic offers OLED modules from brands like Display Visions, Bolymin, Winstar, 4D Systems, and others.
