Micro-lens WOLED displays are a hope for OLED technology. Not only can they achieve similar brightness values ​​to QD-OLED displays, but they are also easier to produce and therefore cheaper.

WOLED – Hope in OLED technology

Screen technologies are constantly evolving to provide people with a better viewing experience. Manufacturers are constantly competing for the next and best innovation. So-called micro-lens WOLEDs are the current hope for OLED technology. They compensate for the previously lower brightness of older OLED technologies, and are cheaper to produce than the well-known QD-OLED displays Samsung has previously relied on.

What is WOLED?

The term OLED is now familiar to many TV enthusiasts and stands for Organic Light Emitting Diode (OLED for short). WOLED displays are special OLED displays that contain white pixels, and thus have the additional term “white” in their name. Unlike older OLED displays, which relied on red, blue, and green subpixels, WOLED displays only require white subpixels.

The colors of these sub-pixels are created by special filters during the image output, which is why the image can be displayed brighter and more balanced than in older OLED models. Due to cheap production costs, WOLED displays are expected to prevail over other OLED technologies.

Modern WOLED panels use so-called micro lens arrays (MLA). With the help of micro lenses, OLED TVs can shine particularly bright and clean. In addition to the true black values ​​already known for OLED technology, it is also possible to obtain pure and bright white. At a presentation in Barcelona last year, Philips compared three OLED displays, including the Philips OLED908, the LG G3, and the Samsung S95C. Only the Samsung OLED TV was the so-called QD-OLED model, whose screen was darker and less clean than the MLA-OLED display.

Philips initially considered investing in QD-OLED displays, but eventually decided to go with WOLED displays. Similar trends can be seen at Samsung. The company signed a contract to supply WOLED panels with LG in the coming years. More and more OLED manufacturers are incorporating WOLEDs into their portfolios.
