Recently, vivo released two flagship mobile phones, the biggest feature of the two mobile phones is the screen, a super large screen, a folding screen, vivo although late, but also finally joined the team of large-screen mobile phones, some people say that vivo this is a helpless move, some people say that the large screen is the trend of the times, is it really so? #手机屏幕 #
Yesterday, Antutu announced the 2022 Q1 user preference list, and the mainstream notes on the Current Android screen are: 6.6 inches, 120Hz, 1080P+.
In this way, it is not necessarily that everyone loves the big screen ah ~ In addition to the screen size, screen refresh rate and picture quality are also within the user's consideration, today is a phase of the mobile phone screen selection guide to share with everyone
Visual effects
Visual effects are the first element of mobile phone screens, which can be divided into two parts: image quality and eye protection.
Quality
Mainly reflected in the screen resolution, that is, how many pixels can be displayed on the mobile phone screen, the higher the value, the higher the picture clarity, the higher the energy consumption. At present, the mainstream mobile phone rates are 2K, 1080P and 720P, respectively. This one is going to go up the whole way.
Screen dimming
Screen dimming is to solve the problem of stroboscopic, screen flicker is caused by current or voltage instability, but also everyone looks at the phone for a long time will have visual fatigue, and even tears, headaches and other problems of the main reason.
When choosing a mobile phone, pay attention to the way of mobile phone dimming, the current commonly used 3 dimming methods are:
DC dimming: DC dc dimming changes the brightness of the mobile phone screen by adjusting the screen voltage or current.
The LCD screen is usually used for DC dimming, but due to poor color rendering, the high-end flagship machines in service rarely use LCD screens.
PWM dimming: By adjusting the time ratio of "light" and "off", the time difference of human vision is used to achieve screen brightness adjustment.
DC+PWM mixed dimming: Select DC dimming at high brightness and switch to PWM dimming mode only when the brightness falls below a certain threshold.
The use of PWM dimming or mixed dimming is usually OLED screen, due to the excellent display effect, there is basically no strobe problem, which is the standard configuration of most flagship machines, but it will also be more eye-hurting.
Touch effects
The control reaction depends on the screen's touch sample rate and screen refresh rate.
Touch sampling rate
The hand sends out various instructions to the mobile phone by sliding the screen, and the higher the screen sampling rate of the mobile phone, the higher the accuracy of the instructions, and there will be no broken contact.
The sampling rate is more accurate to the positioning of the finger on the mobile phone screen, and when playing the game, the mobile phone with the high touch sampling rate will also receive the finger command faster, so as to be one step ahead in the game.
The general screen sampling rate has reached more than 200Hz, this year's Honor Magic4 series screen has supported 360Hz touch sampling rate, and the instantaneous touch sampling rate of iQOO Neo6 released has even reached 1200Hz, basically referring to where to play, without delay.
Refresh rate: High brush screen is one of the biggest advances in mobile phones in the past few years, and the smoothness of mobile phones is improved through the refresh rate.
From the latest statistics, the users of high brush screen (above 90Hz) account for 62.5%, indicating that the high brush screen has basically completed the comprehensive transcendence, of which 120Hz is the most common.
What exactly is the refresh rate? A picture for everyone to intuitively feel:
The domestic market is more internally rolled, when we choose a new machine, whether it is equipped with a 120Hz high brush screen is also a criterion for judging whether the model is sincere or not, and it is correct to choose according to this standard.
Service life
The LCD screen with liquid crystal material has great advantages in the service life, and the OLED screen that has won a complete victory in the color display effect will be slightly inferior.
Due to the aging of pixels, the OLED screen will leave the original display of the afterimage, commonly known as "burn-screen", which will occur about 2-3 years after the screen is used.
And in general, it is irreversible, the only solution is to change the screen, and the cost of OLED is relatively high, which is also a major defect of OLED screen.
Write at the end
In summary, everyone can choose in accordance with the "color development to find OLED, eye protection to choose LCD, 120 high brush must" in the purchase of mobile phones.
