Some are criticizing the Pentile touch screens as a problem.
With the announcement of the Galaxy S3 this month and the expected roll out to much of the world this month, there are those who are criticizing the selection by Samsung of the Pentile display. And with that, it is going to be an ongoing discussion about the use of Pentile displays for the Galaxy S3. While Samsung is calling this the HD Super AMOLED, the Pentile really describes what the screen is and an explanation from Android Authority is shown below. These screens have been around for a while and is not really anything new. The biggest reason that Samsung is using the Pentile display is that the screens do last longer. The Galaxy Nexus, as an example, uses the Pentile display and we did not hear all the fuss that we are currently hearing about the Galaxy S3. Why is that?
It seems that the when the Galaxy Nexus was announced, people were talking about the Pentile display and how it measured up to the iPhone. At that time, the level of the conversation was much lower than it is for the Galaxy S3. All of the Nexus phones have been using Pentile, so for that device it is not something new being added. But the Galaxy S3 is supposed to be a revolutionary phone and it looks like the display is not all the revolutionary.
Part of the reasons for Samsung to stay with the Pentile display are reliability. Since smart phones have to last at least 2 years because of wireless carrier contracts, reliability comes into play. As with any display, pixels do break down and the more that do, the more problems you have with the display. Given that the Pentile displays last longer than the RGb displays being used, it makes sense for Samsung to use the Pentile display. For a great explanation, head over to Mobile Burn for a great run down on this.
The latest iPhone was expected to be a revolutionary phone, but was not. The Galaxy S3 was expected to be a revolutionary phone and in some respects it is not. But both of these phones are going to sell very well. With most people, they will not notice the difference between the RGB and Pentile displays, there are those who are critical of the less than crisp displays on the coming Galaxy S3. In the end, it will be the consumers who pass judgment by the purchases being made of the Galaxy S3.
In closing, here is a clarification from Android Authority providing a good explanation as to the differences between the RBG screens and Pentile screens of today.
RGB or PenTile – What is the difference?
Before getting into the subject, let’s quickly talk about PenTile and RGB and explain in a few words the two technologies. RGB means “red green blue” and is generally used to refer to the sub-pixel matrix used in a display that sees three individual sub-pixels (one red, one green, one blue) making up a complete pixel. The red, green, and blue sub-pixels exist as vertical bars, each one measuring a third of the width of the full pixel.
In contrast, the PenTile matrix uses five sub-pixels in a different formation. They can act as a part of numerous logical pixels, and they often contain pure white sub-pixels. PenTile displays are perceived as brighter than RGB screens, but many display purists consider them fuzzier and overall inferior to the classic RGB.
