After the release of Microsoft Surface RT, the official release of 10.6-inch, 1366 × 768 resolution and other information, many consumers The screen effect has been questioned. If we only look at the resolution parameters, the surface RT and the new The gap is still large, even can only be compared with the generation of iPad. In view of this, let's first understand the pros and cons, and finally add the comparison of actual effects and subjective experience.

1、 The explanation given by Zhengfang Microsoft:

Resolution is only a factor to measure the display effect, and the most accurate measurement standard of display effect should be the screen's analytical ability, which is called the modulation conversion function (MTF). MTF is a function of contrast, resolution and other parameters. In addition, there are dozens of other parameters that will affect MTF.

Among these ten factors, we mainly discuss resolution and contrast. The survey shows that when the resolution is improved, the sensitivity of the human eye will be reduced, which means that when the resolution of the iPad reaches a certain level, the intuitive experience of the human eye cannot be greatly improved. At this time, the contrast is more important. Surface is better at contrast. Although its resolution is lower than that of iPad, the advantage of contrast in overall display performance can level the score or even surpass that of iPad.

So, how does Microsoft improve the contrast experience? Official supplement: First, Microsoft has the ClearType pixel rendering technology, which is more unique on the Surface and better than the Windows desktop version. Secondly, Microsoft has adopted the LCD screen with high contrast and wide viewing angle, which makes it outstanding from the screen material. Finally, Microsoft's screen glass is also very excellent at present. It is not only thin but also has good optical performance, which can greatly reduce the screen reflection, and the reflection will be more excellent when reducing the contrast. According to unofficial data, the reflective ratio of the surface screen is 5.5% to 6.2%, while that of the iPad is 9.9%.

2、 Opposition:

The display screen of Surface RT adopts sub-pixel rendering technology, supplemented by ClearType font to bring smooth effect; The iPad series uses standard pixel rendering technology. The sub pixel rendering technology of Surface converts red, green and blue colors into independent picture elements instead of binding the three colors together. Its image pixels are special. The screen with sub-pixel rendering technology is three times as sharp as the screen with traditional normal pixel rendering technology, but it has no advantage over Apple's standard pixel rendering technology.

As for the improvement in screen materials, glass materials and other aspects, it is not as good as Microsoft claims. Apple's advantage in high resolution will be greater, and Microsoft can hardly avoid the suspicion of "boasting".

3、 Comparison of live shooting effects:

Next, we take the Surface RT and The New iPad to compare their actual effects and intuitively reflect their performance.

1. Outdoor display effect

In this link, we investigate in the outdoor scene environment. Adjust the brightness of both machines to 100%, and then compare them in the mode of browsing web pages, pictures, etc. The picture was taken at 3:00 p.m., and the sunlight was being photographed.

Because the camera is difficult to achieve the effect of human eye recognition when imaging, it is difficult to see the difference between the two from the photos. It is true that the display effect of the surface and the iPad in the outdoor is indistinguishable, but I still feel that the surface is slightly better. At the same time, I can be sure that both of them are OK for outdoor use.

2. Indoor display effect

The outdoor scene can well contrast the screen reflection effect, and the display effect of Microsoft and Apple products in the outdoor environment can be well reflected. In this scene, we adjust the background brightness to 100%.

Indoor display contrast is mainly from browsing web pages and pictures. The surface effect is warm, but the iPad is better in saturation.

3. Delicate contrast:

Use the same SLR to aim at the text in the same area of the Surface and iPad respectively for shooting. The shooting distance and SLR settings are the same. After the shooting is completed, the photos are magnified at the same scale for comparison.

In the above figure, the upper part is the surface and the lower part is the iPad. It can be seen intuitively that the iPad is much more exquisite than the Surface.

4、 Personal subjective experience:

From the perspective of personal experience, first of all, the screen size and proportion of the Surface RT and The New iPad are different, The surface is longer and the iPad is wider. These two different designs are suitable for different use environments. If you want to browse the web, the iPad is certainly more suitable, while watching videos, the surface is undoubtedly a better choice. Users can make choices according to their own preferences.

From the above figure, we can see the difference in the fineness between the two. In actual use, the fineness of the iPad can be clearly felt. Although the resolution of the Surface is the same as that of the traditional notebook, the screen is small, but because it is closer to the human eye when used, it can easily feel the graininess. From the perspective of reading experience, the iPad will undoubtedly be better.

In terms of saturation, it is surprising that the iPad is better than the Surface, which can be intuitively felt in the process of browsing pictures. And because of the high resolution of the iPad, the picture is more soft and delicate, and the surface is not as good as this.

In terms of temperature difference, Surface is also quite different from iPad. The surface screen effect is warm, while the iPad screen effect is cold. Warm colors are more comfortable when reading text, but the difference in fineness makes the overall reading experience of the Surface not keep up. The preference for color also varies from person to person.
