LG Display is working on the next generation of OLED panels that could bring a noticeable boost to screen capabilities. The company is developing a design using as many as five emissive layers, while the most advanced TVs currently use four. The new technology should increase brightness and extend panel lifespan, although it will be more expensive to manufacture.
Five OLED layers aim to deliver greater brightness and longer screen life
According to the Korean site The Elec, LG Display is developing a 5-layer OLED panel that will be the next step in the development of Tandem WOLED technology. LG Display’s most advanced panels currently use four emissive layers, while the new design will receive an additional blue layer. This should allow the manufacturer to boost the panel’s capabilities without sacrificing the advantages of OLED. A higher number of emissive layers can translate mainly into greater brightness and a longer screen lifespan. That is particularly important for large televisions and monitors, where users increasingly expect very high HDR brightness. At the same time, a more complex design will be more difficult and costly to manufacture. LG Display is therefore also working on solutions that go in the opposite direction. The company is reported to have recently developed a 2-layer OLED for cheaper televisions and monitors, intended to reduce production costs compared with current panels.
New OLED could make it into Apple's first OLED iMac
One of the most important uses of the new technology may be a future iMac from Apple. LG Display is said to have already developed a 27-inch 5K OLED panel using four layers, which is being considered as the display for a future Apple computer. The company is reportedly working on an even more advanced design, because Apple expects very high image quality for its first OLED iMac. According to current reports, Apple does not plan to introduce an OLED iMac until around 2029. Both LG Display and Samsung Display are working on suitable panels and are competing to supply Apple. Samsung is already developing 5-layer Penta Tandem QD-OLED panels, so LG Display will have to offer a solution of sufficiently high quality to secure the contract. The technology could, however, find applications beyond Apple computers. If production costs can be properly optimised, 5-layer OLEDs could in future also appear in TVs and premium monitors.
LG Display is developing a new generation of 5-layer OLED panels that are set to offer higher brightness and longer lifespan than current Tandem WOLED designs using four emissive layers. The solution could be used in the most advanced TVs and monitors, but the potential link to Apple’s first OLED iMac is particularly interesting, with its debut currently expected around 2029. LG Display is competing here with Samsung Display, which is also developing 5-layer OLED technology.
