The next generation Apple iPhone 13 is likely to hit the market later this year, and if the rumors we've seen so far are empty, it should be a pretty impressive package. Reports claim that the device will start with advanced video recording technology, longer battery life, a smaller “notch” and a 120Hz refresh rate (a first for Apple phones).
Even a report from LG last Christmas suggested that Apple start implementing Always Display technology on its latest devices. According to the report, LG is making low-temperature polycrystalline oxide (LPTO) panels for Apple's low-end iPhones. These boards allow devices to receive highly variable refresh rates - depending on what each manufacturer allows, the number can be as high as 120 Hz or 10 Hz. 10Hz is almost the same as an iPhone, or any other modern phone needs to achieve an always-on display without much battery drain. The higher the refresh rate, the faster the battery charge. Combined with OLED, LPTO panel technology can keep refresh rates low if you don't need 60 or 120 Hz, and always stays in certain parts of your screen. This can include the time, date, time, outside temperature, and more.
