The topic of whether the iPhone 12 series supports 120Hz screen refresh rate is controversial, but according to the latest information and IOS 14 test version, only the high configuration version of the iPhone 12 promax will be equipped with this function. And there’s lidar. This has almost confirmed the major upgrade of the iPhone 12 Series in terms of hardware, and foreign reviewers have got the iPhone 12 promax tester in advance, and have a hands-on experience, which proves that the two major functions are stable. < / P > < p > foreign informant Jon Prosser has accurately predicted the release time of the product in the past few years, even this year’s new iPhone release time is accurate. According to two screenshots of iPhone 12 promax exposed on the Internet, the button to activate the adaptive refresh rate is displayed. It is also explained below that the user can reduce the refresh rate of the screen display from 120Hz to 60Hz according to the demand. < / P > < p > to confirm that the interface is not fake, Jon Prosser also recorded the process of iPhone 12promax switching to 120Hz refresh rate, and also showed the body shape, with little improvement in bangs. According to Jon Prosser, apple currently has multiple internal testers, but not all of them are equipped with a 120Hz refresh rate. At present, apple is testing the performance of the iPhone 12pro and 12promax at 120Hz refresh rate. If there is no accident, they should both support it. < / P > < p > and everythingapplepro, another apple whistleblower, also exposed two photos of the iPhone 12promax tester on the social platform, which also showed the switch to activate the adaptive refresh rate, almost confirming that this function should be stable. However, it is disappointing that the bangs of the iPhone 12promax tester are not likely to be narrowed as previously rumored, but still maintain the original width. Even if the screen is raised to 6.7 inches, the bangs still remain unchanged. According to the above news, both the 6.7-inch iPhone 12 and the 6.1-inch iPhone 12 will adopt a 120 Hz refresh rate, while the 5.4-inch iPhone 12 and the 6.1-inch iPhone 12max will not support the 120Hz refresh rate, so the price should be cheaper. At present, the mainstream screen of smart phones is OLED panel. Apple’s iPad Pro has supported five refresh rates of 24Hz, 48Hz, 60Hz, 90hz and 120Hz. The iPhone 12 system should only support 60Hz and 120Hz refresh rates, which will be automatically adjusted according to different states. For example, when playing games, watching videos and other dynamic interfaces, the 120Hz refresh rate will be automatically activated. If you are watching news or chatting, it should be automatically adjusted to 60Hz. The main purpose is to save power and improve battery life. < / P > < p > in addition to the 120Hz refresh rate, Jon Prosser also exposed a screenshot of the ios14 camera settings, which shows the lidar lens switch. This almost confirms that the iPhone 12 promax will use lidar scanner lens. However, the iPhone 12 promax supports more options than the iPad pro, and further illustrates that the perspective lidar scanner can greatly improve the night scene and video recording. Mainly when taking photos or videos, with the help of lidar’s powerful recognition and focusing function. < / P > < p > this time, foreigners experienced PVE testing machine, which is called production verification test stage model in Chinese. In other words, before the official release of the new machine, the tester is mainly used for the verification of various functions. More often, the testing machine will be directly converted to mass production machine after verification, which is also the last stage before the new machine production. From the experience of the iPhone 12 promax tester, the two functions are more powerful than expected. They are likely to be only used in high configuration version, and the price should be more expensive! Continue ReadingAmerican companies begin to give up R & D: who should pay for corporate research?
