Nowadays, the new flagship mobile phones of major brands tend to use higher specifications and more advanced screens, such as familiar curved screens, high screen ratio, high brush screen, high resolution, on this basis, LTPO screen technology has begun to be frequently mentioned by many mobile phone manufacturers in the past year. The newly released Honor Magic4 series, OPPO Find X5 Pro, Xiaomi Mi 12 Pro, and last year's Apple iPhone 13 Pro/Pro Max all use this technology that can make the high brush experience more power-efficient. Not to say that I don't know, although LTPO is a general-purpose solution, but the models of different manufacturers, often there will be a big gap in experience, how should consumers choose?
You may wish to take a look at the following comparison chart, the same is the screen of LTPO technology, honor Magic4 Pro in low brightness only a subtle strobe, and iPhone 13 Pro in the same conditions, due to only 480Hz PWM dimming, the screen strobe has been unable to look directly. Strobe injuries, light is easy to cause visual fatigue, heavy damage to vision. In order to minimize the strobe of olED screen, the Honor Magic4 series has brought an industry breakthrough, based on LTPO screen to provide high-frequency PWM dimming, eye protection effect is remarkable.
Speaking of this, some netizens may ask, some manufacturers do not have DC dimming, what is the difference between the two? Why do PWM dimming? To put it simply, DC dimming and PWM dimming are both paths to deal with stroboscopic, but DC dimming is prone to problems such as color casts and smearing at low brightness, resulting in discounts when the screen experiences low brightness, so high-frequency PWM dimming has become another direction of exploration.
According to Zhao Ming, CEO of Honor, the LTPO technology of existing display panel manufacturers can only achieve 480Hz dimming itself, so Glory began to actively communicate with screen suppliers such as BOE in the early days, at the expense of increasing costs and investing more research and development energy to seek breakthroughs. Combined with a series of software and hardware deep tuning such as driver IC customization, circuit improvement, algorithm optimization, etc., the final Honor Magic4 series once again created a precedent, the industry's first LTPO dimming + 1920Hz high-frequency PWM dimming, breaking the ceiling of innovation and experience, bringing users a better eye protection experience.
Next, compare several other representative flagship machines, Huawei P50 Pro and Mate40 Pro are also taking the path of high-frequency PWM dimming, both models provide 1440Hz PWM dimming, but unfortunately they are not equipped with LTPO technology. OPPO Find X5 Pro and Xiaomi Mi 12 Pro have LTPO technology, but only 360Hz low-frequency PWM dimming or 360Hz low-frequency PWM+ DC dimming, low-brightness use scenarios are not eye-catching. The Honor Magic4 series realizes the combination of LTPO and 1920Hz PWM dimming, which can truly meet the user's eye protection needs in all scenarios.
In addition to the different solutions for eye protection, in fact, the algorithm optimization of LTPO technology by different manufacturers is also quite important. Previously, some consumers specifically picked models with LTPO technology to start with, but after experiencing it, some would complain that they did not save electricity, and some would complain that mobile phones sometimes stuck. Some early users of Xiaomi Mi 12 Pro feedback that its LTPO dynamic adaptive high refresh rate is still not smooth or stuttering when switching apps, which shows that the adaptation and detail tuning of a large number of software is a greater challenge for the algorithm team. The dynamic refresh rate adjustment of the Honor Magic4 series, combined with a large number of use cases, is repeatedly polished to achieve an accurate match between the refresh rate change curve and the change of the user's touch sliding speed. Compared to the dynamic refresh rate experience of some Android phones, the Honor Magic4 series can really make the whole process very smooth and comfortable.
In terms of other screen specifications, from the above parameters of a variety of flagship machines can be seen, the Honor Magic4 standard version such as true 1.07 billion colors, curved screens are also arranged, and some consumers are more concerned about the resolution and PPI pixel density, OPPO Find X5 Pro and Xiaomi 12 Pro are higher.
On the whole, the Honor Magic4 series brings an excellent configuration of the screen, with the control of a powerful algorithm, Honor also makes LTPO better to use more eye protection, it can be said that in a variety of domestic flagship machines, its screen experience is outstanding. With the significant progress of key screen performance, the comprehensive strength of the Honor Magic4 series starting from 3999 yuan is indeed stronger, and it is a flagship machine that can truly solve consumer pain points in all aspects.
Keke comments: The Honor Magic4 series has a further good screen, not only pleasing to the eye, but also more eye-pleasing and silkier, which can really make the key screen experience go further.
