LG has developed MicroLED displays for smartphones: LG G8
The principle of the MicroLED displays is similar to the usual OLED displays, since its operation does not require a general illumination of the panel, and each pixel is capable of emitting light independently of the others.
However, MicroLED technology uses much smaller pixels and uses organic connections other than those used by OLED displays. As a result, the MicroLED panel should have an incredible margin of brightness, low thickness and low cost, but the very process of manufacturing them will be technically much more difficult. At first, the complexity of production will be leveled by the cost, but over time, such displays will even be cheaper than currently used OLED-panels.
Earlier this week, there was a leak of information that Apple is currently developing MicroLED displays on a secret facility in Santa Clara, California, USA. But from the latest news, it became known that LG filed an application for the registration of trademarks XμLED, SμLED and XLμLED. As we know, the symbol “μ” means “micro”. The first letters (X, S, XL) are, apparently, the size. The list of devices with which LG plans to use this trademark includes smartphones, watches, tablets, laptops, VR glasses and many more. Note that LG is a supplier of displays used in Apple Watch, and the company from Cupertino is gradually trying to lose its dependence on suppliers, expanding its own production capabilities.
LG G8 can be the first smartphone to feature MicroLED display, and at the moment commenting on the specifications, and other features of such display in a smartphone are difficult. Well, looking at the present technology scenario the cost of the smartphone might be increased a little, but the overall performance of the display will be in favor of a smartphone. It will have a better battery life, and even smartphone can feature 4K resolution in a size of 5 to 6 inches display.
