Rumors suggest that the Apple Watch 2 will come with a thinner screen made of a single sheet of glass. With this "one glass solution" display, Apple seems to be aiming to achieve longer battery life.

According to TechRadar, the second-generation Apple Watch will move to a "one glass solution" (OGS) display that will help the wearable device become thinner overall. According to Digitimes, TPK Holdings, which is Apple's display supplier, revealed that the company is currently working to make the transition in the upcoming Apple Watch 2 from a glass-on-glass panel to the new OGS display.

Up to date, traditional touch screens have been manufactured using glass-on-glass technology by integrating electronic components between two sheets of glass. MacRumors reports that the OGS display technology will eliminate one of the layers of glass from a traditional glass-on-glass display, replacing it with a thinner material. This way, the Apple Watch 2 will provide more space for a larger battery by moving to an OGS display.

Most of the smartwatches on the market, including the original Apple Watch, have suffered from short battery life. One of the solutions used by smartwatch makers against this inconvenient has been turning off displays automatically when not in use. This is saving battery life indeed, but also is making it difficult to get access to information quickly enough.

An OLED display combined with better battery life could enable the next generation Apple Watch 2 to finally display the required information without the need for users to awkwardly lift their arm. It is also speculated that the upcoming Apple Watch 2 will include a GPS chip in order to help runners track their activity without carrying their iPhones with them.

Most of the changes in the upcoming Apple Watch 2 are expected to come in the form of software under the hood. The wearable device's exterior is likely to keep the same design as seen in the first generation.
