[Q] IPS Display

---

If IPS display is so good, how come no other major manufacturer is using it?
Everyone else is going for TFT.

No other major manufacturer, really? Apple uses them in iPads. B&N uses them in Nooks Color. Lenovo will use it in LePad tablet. I believe Toshiba will use it their upcoming tablet. I think that's enough but there may be others too, we just don't have final specs on all upcoming tablets yet.

Some manufacturers don't use them (motorola and acer for example) to cut costs and make bigger profit I am guessing.

A lot use them. Those that don't do so to cut costs.

Everyone is going for TFT because every LCD is using TFT (thin-film transistor). IPS is also TFT-LCD.

There are three main types of TFT-LCD:
TN - very cheap, poor angles, contrast and colors (almost certainly used by Acer A500).
VA - good black and contrast, not so good angles (but quite OK), slow, good colors but most suffer from black crush (the colors near black all look like black), probably used by Motorola Xoom,
IPS - very good colors, good angles of view, worse black than VA, faster than VA, slower than TN, probably costs more than most VA, used by iPad and Transformer.
There is also AFFL - Asus used it in Asus Slate but named it IPS if I remember correctly (it should be very similar to IPS).

There are many other versions, especially VA is in many different versions - some worse, some better. The type of backlight (typically fluorescent lamp, sometimes LED) will also have impact on colors.

kinda like how porterhouse is better than cube steak... everyone doesn't eat porterhouse cause it costs more.

now just to clarify, i know it's a personal preference as to which meat is better b/c there's a bbq joint here that makes a cube steak that i'd pick over a porterhouse any day!

a 24" standard TN display will run you starting at $170

The cheapest IPS display will cost you $400+ for the same size.

comes down to cost, and yes I do have two IPS displays, I will never go back to anything lower, putting it beside my TN panel acer, the acer looks like a POS.

Winner, winner, chicken dinner.

I didn't think the colors looked that good on the xooms display when I saw it in store and when I saw the xooms screen compared to the transformer in a review (can't remember which sorry) I thought it looked pretty terrible..

tests by anandtech show the transformer being better at showing blacks AND contrast so I doubt the Xoom is a VA panel.
