withMobile phonesThe market is becoming increasingly competitiveMobile phonesManufacturers have launched new phones, and one of the highlights that has attracted much attention is the screen"Brightness"。Recently, Xiaomi andMeizuThe Redmik70 series has been released one after anotherMeizu21 series, and in the coming week, we will welcome new devices from OnePlus, Realme, and iQOO. However, if there is one bright spot in this race for new phones, it is the brightness of the screens claimed by various manufacturers. In this week, Xiaomi announced that the peak brightness of the Chinese screen equipped with Redmik70 K70Pro has reached 4000 nits, followed by OnePlus announced that the peak brightness of the Oriental screen equipped with the OnePlus 12 series has exceeded 4500 nits, and then realme also announced that the brightness of its dual-screen has reached 4500 nits. The increase in screen brightness has attracted people's attention, but is it a technical improvement or a publicity gimmick?
First, let's take a look at the definition of screen brightness. Screen brightness refers to the intensity of the screen's glow, which is usually measured in nits. InMobile phonesIn the field, the improvement of screen brightness is based on the user's demand for higher brightness. With people using it outdoorsMobile phonesAs the demand increases, so does the demand for screen visibility. Therefore,Mobile phonesManufacturers are constantly working to improve the brightness of the screen to ensure that it can be clearly seen in bright light environments. This is also the gimmick why various manufacturers announce the increase in screen brightness.
However, this increase in screen brightness didn't come out of nowhere. fromiphone15 nits peak brightness starts with 2000 series, othersMobile phonesManufacturers have also launched brightness enhancement products. However, it should be noted that the peak brightness advertised by the manufacturer does not necessarily represent the real screen brightness, or even the quality of the screen. Many manufacturers are confused in the publicity"Local peak brightness"with"Global peak brightness"The concept of direct use"Peak brightness"word, misleading consumers into believing that its screen brightness is ahead of the restMobile phones
Local peak brightness refers to the highest brightness when only a part of the screen is litOLED screenon is a characteristic. Due toOLED screenofPixelsIt is self-illuminating and does not need to have a backlight layer like an LCD screen, so it can only light up part of the areaPixels。Under certain conditions, these are litPixelsis able to excite higher brightness, thus obtaining the so-called"Local peak brightness"。However, the definition of local peak brightness varies from manufacturer to manufacturer, so direct comparisons are not possible.
In practice, the brightness of the screen depends not only on the peak brightness, but also on the accuracy of the automatic brightness adjustment and the range of manual brightness adjustment. Mobile phonesManufacturers should focus on improving the automatic adjustment algorithm of screen brightness to achieve different lighting environmentsAdaptiveShifts in brightness. In addition, it provides a wider range of manual brightness adjustment, which can meet the user's brightness needs in different scenarios.
Overall, the increase in screen brightness is indeedMobile phonesManufacturers are advancing in technology, but consumers are choosingMobile phones, the quality of the screen should not be judged by the peak brightness alone. A combination of factors should be considered, including factors such as brightness range, auto-adjustment algorithms, and color accuracy. The most important thing is that users should choose the right screen brightness according to their own usage needs, rather than blindly pursuing the highest brightness.
