Foldable displays require thinner display panels, more durable flexible materials, and lower power consumption display technology, but, according to 9to5mac, Apple has begun developing a new, thinner OLED display that can be folded. The technology described is similar to that used in the Samsung galaxy z fold 3. In order to make the panel thinner, more durable, and lower power consumption, it will need to compromise on technical specifications such as panel brightness, and Apple is unlikely to compromise on immature technology. According to previous reports, the first generation of Samsung galaxy z fold uses a polarized sheet to make the panel thinner, but the light transmission is not good, affecting the screen brightness, in order to improve the brightness, it will improve power consumption and reduce the screen life. We usually wear polarized sunglasses, you can filter out part of the dazzling light, reducing the brightness. According to The Elec, Samsung's third-generation ga
