This is the first article in our new series ‘Explained’ – a series of articles that highlight a few important features of the Samsung Galaxy S3 explain – not for the seasoned smartphone fanatic, but for anyone who ever that is interested in a device like the Galaxy S3, but a little dizzy from all the technical, trendy terms such as Quad Core, Android, and Super HD AMOLED.
This last term steps we therefore depend: AMOLED, or in the case of the Samsung Galaxy S3: Super AMOLED HD. You see the term everywhere in leaflets, on websites and in the product information in shops. But what does it mean? And why is it so useful to mention this?
Super AMOLED HD (screen)
To explain this it is useful to know that there are roughly two types of displays used in smartphones: LCD and AMOLED displays. The major difference between these two lies in the way the screen is illuminated. An LCD screen has separate lighting to the image on the screen visible. In a screen AMOLED rays of light from the pixels themselves, without the need for more lighting is used.
This creates the huge difference between the two screens. If an AMOLED display the ‘color’ black display is simply no light emitted. This contrasts with an LCD screen, which also black – or dark colors – just relieved. The difference: the contrast of the AMOLED screen is larger than that of an LCD screen. This gives a very nice ‘effect’: black is really black, dark, really dark. And bright colors seem to really like the splash screen. An LCD display shows – compared with an AMOLED screen – a rather dull image.
Yet you can not simply say that AMOLED screens so prettier or better than LCD screens. The color reproduction of a good LCD screen is more natural than that of an AMOLED display – in the real world colors are not as bright as an AMOLED screen. And where AMOLED screens appear as black really black, LCDs are actually better at displaying white as true white. A few years ago was the difference between the two screen types are great – today is the color of AMOLED screens increasingly natural, and contrast of LCD screens getting bigger. Therefore, the differences between the two screen types now very small. An example of a smartphone with a very good LCD screen is the HTC X One .
The ‘term’ HD is probably a lot more understandable, even for non-smartphone enthusiasts, and of course stands for High Definition. It says nothing else about the screen a amount of pixels available – in this case 720 pixels in width – and thus may be classified as HD. So you can look for example on YouTube in HD quality.
We still need to mention what that word ‘Super’ still does. Once there were namely is gewone’Amoled screens. These were put it simply, of two layers: a layer which displays an image, and a layer which is sensitive to touch. Today, these two layers are merged in a single layer. The name for this is Super AMOLED. The advantage of this means a thinner screen. Yet the word ‘Super’ is no longer as relevant – it would have been quite startling to have a flagship smartphone released without ‘Super’ but with ‘AMOLED screen.
In summary, you could say that an AMOLED display screen, one of the two major types that you meet in smartphones (LCD being the other). An AMOLED screen has no special lighting is needed – or an LCD screen. This is an AMOLED display more contrast than an LCD screen, but again has a somewhat less exact color reproduction. Today, the differences between both types of screen a lot smaller than a few years ago.
So far our explanation of one of the terms that you repeatedly meet in combination with the Samsung Galaxy S3. Next time: ‘Quad Core’.
