HTC One Full HD, D2 and Xperia Ascend Z

0

Display Mate’s boys are famous for their precision measurements on all types of variables related to device screens. Not the first time we talk about them here, because we saw a while ago its analysis of S4 Galaxy screen.

Now bring us an analysis of the other three terminals screens star of this year, the HTC One, Huawei Ascend D2 and Sony Xperia Z. Full HD devices that tell one by one all its features.

In the first few numbers we can make it clear that these three screens mark a full HD 1080p 4.7 inch diagonal for HTC One and 5.0 inches for the other two opponents. This causes the first screen is 12% lower in the area Z and Ascend Xperia D2, which raises its pixel density of 443 to 468 ppi, lowering in turn the distance at which the human eye resolves the pixel of 19.8 to 18.5 inches.

Calibration of color, viewing angles and reflections

Entering specific aspects, starting with the color, the phone takes the best score for fidelity in color reproduction is the Huawei terminal with an ‘excellent’ color and pictures ‘very good’, the other pair of devices are in “good” images due to saturated colors in the case of Z Xperia, contrast is defined as not required.

This is because, according to Display Mate, for the HTC One and Xperia Z worsen the quality of your screen through processing that makes images. While the Xperia Z the Bravia Engine can be disabled, it is not in the Taiwanese model.

As for the viewing angle, is the section where many will know beforehand as the Sony model is worse off. Not only in the loss of gloss with an inclination that is general in LCD displays, but in contrast, where the HTC One obtains a contrast three times (x4) and Ascend D2 approaches the triple.

In reflection, the three terminals get get a score ‘very good’, where Huawei model rises from 5.6% to 6.5% peers when it comes to light in all directions but is closer when we speak of ‘mirror reflection’ that is by 6.9% compared to 6.5% of HTC One and 6.7% the Sony model.

Brightness, contrast and battery consumption

Getting to shine, we see that the One takes 491 nits, the D2 421 nits and 478 nits Xperia Z, with black brightness levels of 0.4 nits for the One – which drops to 0.28 in dynamic contrast – and Z, which up to 0.57 in D2 Ascend.

In contrast we see that the HTC One takes the cake, with 1,228 points, which are on 739 points Ascend D2 and practically equal to the Xperia Z in 1226. The difference here is that the One has a dynamic mode that lowers the brightness level when a high proportion of black. In this case this phone up your brand to 1,754 points. In the presence of high levels of light phones remain respectively at 88, 65 and 85 points of contrast, due primarily to the maximum brightness and glare.

As for battery consumption, point in favor of LCD over AMOLED screens, we see very similar results. Speaking of completely blank screens, we have 1.05, 1.12 and 1.21 watts, which if normalized to 5-inch screens to 421 nits we have 1.03, 1.12 and 1.07 watts, which would definitely give this point to HTC One

Compared to the iPhone 5 and Galaxy S4

Beginning with the iPhone 5, riding a reference screen LCD field. Recall that this device runs on the famous resolution of 326ppi retina in 4 inches diagonally. Apart from this, the numbers are skewed in favor of Apple when it comes to maximum brightness at 556 nits, and reflexes, at 4.5%. This encourages low contrast bright almost double the D6 Ascend result in very light reading and improve the other pair of terminals around 50% with 121 points of contrast.

As for color fidelity, the one who bucks this reference is the Huawei Ascend D6, which matches the color reproduction quality of Apple in a resolution, and diagonal pixel density much higher. By contrast, the HTC One and Xperia Z remain “one or two steps behind” these phones in these sections.

Concerning the Galaxy S4, which we did together to review Galaxy SIII and iPhone 5, it should be noted that this AMOLED technology is very different from LCD panels. To summarize, this screen is better in terms of reflexes, which remain at 4.4%, which makes the contrast in highlights reaches 108, closer to the iPhone 5 that these mobile screens.

Another difference to note is that the Galaxy S4 uses a Pentile matrix 5 inches Full HD, lowering its density sub pixels per inch in red and blue to 312. Finally, blacks consider blacks we see in these screens, which increase its contrast to the infinite dark. While this Amoled screen is much improved, still has a section in which to approach the LCD, such as consumption, which exceeds figures around 50%.

Conclusions

What we have are three smartphones with Full HD screens among which is easier to decide who loses to do the same with who wins. The Sony Xperia Z falters in sections such as angles of vision, common in low-end smartphones and “inexcusable on a top of the line product” washing the image even at relatively low inclinations.

Then we have the HTC One, which adds points apart as pixel density – if that still counts to these figures – and in point of contrast, thanks to its dynamic mode and high maximum brightness.

Finally we have the Huawei Ascend D2, which is not particularly outstanding in many ways, but finally made the top spot. This is because the areas in which it fails, as reduced brightness and higher contrast reflections relatively short distance from the other pair of telephones. It is finally with a grade A.

Either way staff and in conclusion, I think the winning screen – and considering that phones are aimed at the average consumer where color accuracy is not as important – is the HTC One More maximum brightness – it always is appreciated in the street, the usual place for a phone – lower consumption, better inclinations and reflex response and a higher contrast also equipped with a dynamic mode that increases around 40% in dark samples give to me this position.
