Over the past few years, we’ve seen an absolute explosion of activity in the OLED monitor space. What was once a niche panel option available on premium laptops has wonderfully spread to encompass the best gaming monitors for desktop PCs. That makes understanding the inner workings of the panels more important now than ever, especially when it comes to burn-in, the most common source of anxiety for potential customers. Below, we'll outline why this occurs, and this guide will also teach you how you can prevent it.OLEDs differ from traditional LCDs because each pixel in the panel emits its own light when current passes through it. This design means there is no need for a separate backlight to illuminate each pixel, unlike LCDs. So, to display black, the individual pixels can be turned off, allowing true “inky” blacks, infinite contrast, and vibrant colors unmatched by LCD-based monitors. That means the necessary pixels are turned off when representing the color black.The different types of OLED monitorsThere are several types of OLED monitors, with WOLED and QD-OLED among the most popular. WOLED monitors feature red, green, blue, and white subpixels overlayed on a white OLED layer. The white light passes through the red, green, and blue filters to produce color, while the light passing through the unfiltered white subpixel can be used to enhance overall brightness (and to compensate for the inefficiency of the color filters).QD-OLED monitors, on the other hand, use a blue-emitting layer instead of WOLED’s white layer. Furthermore, the light passes through a quantum dot layer without the need for color filters, which helps to boost color saturation compared to WOLEDs.
