Before we discuss OLED burn-in, we must first explain what exactly makes up an OLED. OLED stands for organic light-emitting diode. It’s the “organic” in the name that can cause issues with extended use. The use of organic compounds makes OLED panels more fragile and susceptible to power input and high sustained brightness levels. In addition, OLEDs provide their own light source, as they are self-illuminating. Over time, these self-illuminating diodes will lose brightness and will appear dimmer to the naked eye as their luminescence degrades. When these overworked diodes sit next to diodes tha
