Thread: hd or xga

I found this...::

* VGA - 640 X 480
* SVGA - 800 X 600
* XGA - 1024 X 768
* QVGA - 1280 X 960
* SXGA+ - 1400 X 1050
* UXGA - 1600 X 1200
* QXGA - 2048 X 1536
* QSXGA+ - 2800 X 2100
* QUXGA - 3200 X 2400

* WXGA - 1280 X 800
* SXGA - 1280 X 1024
* WSXGA+ - 1680 X 1050
* WUXGA - 1920 X 1200
* QSXGA - 2560 X 2048

HD is a misnomer ...used too often...to make products seem more expensive/valuable than they really are...

So are we talking about pixel count? If so at what point is something considered hd? What about TFT COLOR.....does this affect weather or not a particular item is hd or not?

A thin-film-transistor liquid-crystal display (TFTLCD) is a variant of a liquid-crystal display (LCD) that uses thin-film transistor (TFT) technology to improve image qualities such as addressability and contrast.

Are the TFTs staggered or coplaner or inversed staggered or a combination construction?

There appears to be several ways that the TFT can be use for different aplications. Types of TFT LCD Displaysby*Admin6/12/2012

TFT stands for thin-film transistor, and this variety of LCD represents the highest-end commercially available liquid crystal display screen. TFT is the technology used in televisions and computer monitors, though the latest crop of mobile phones and tablet devices also use TFT LCD displays.

However, not all TFT displays are created equal. If you need your*TFT display*for a certain function, if you're passionate about viewing angles and color brilliance, or if you just want to be in the know about LCD technology, you need to be aware of the many different types of TFT LCD displays.

Twisted Nematic (TN)*- TN displays are the cheapest type of TFT LCD displays. They have 6-8 bit color technology, and their max contrast when viewed straight on is 1000:1. When viewed from a 60 degree angle, TN displays only have 10:1 contrast. The max horizontal viewing angle is 60 degrees and the max vertical viewing angle is 15 degrees.
Multi-domain Vertical Alignment (MVA)*- MVA displays are a mid-range type of TFT LCD displays. With 6000:1 contrast, they improve upon TN technology, but they tend to be more expensive. The horizontal viewing angle is increased to 100 degrees while the vertical angle is 30 degrees, making it easier to use on a mobile phone or tablet that may be held and used at an angle. The max color quality of MVA LCD displays is 10-bit.
Super In-Plane Switching (S-IPS)*- Also known as Super-LCD displays, S-IPS displays rival AMOLED displays in terms of quality. They are a mid-ranged option that are less expensive than their LED counterparts, and they use significantly less energy than either TN displays or MVA displays. The level of contrast doesn't change as drastically with a wider viewing angle, though the contrast is comparable to TN displays. S-IPS displays offer near 180-degree vertical angle viewing and a stunning 150 degree horizontal angle viewing.

It is all about column and rows. A display is a grid of these cols and rows. Just like your telephone is a column and row. Take button one on a phone. That would be row 1 column 1. Button 2 would be row 1 column 2. Button 3 would be row 1 column 3.

Button 4 would row 2, column 1. Button 5 would be row 2, column 2. Button 6 would be row2 column3.

Understand the pattern?

Well that is how pixels are arranged, but just more complicated that a 4 row, 3 column telephone key pad. But, this is the jest of it.

If you touch a screen and it is soft, the it is a passive display. An active display would be hard (glass).

So when a a monitor reaches *VGA - 640 X 480 this were hd starts ?
