For now the TV screen LCD TV and LED TV uses a different Panel. Many people may be wondering how do you "Panel" Each of them are different. Including the pros and cons, and then we should not use any of it. But do not worry! This article will take you to the Panel recognized that the three used in the IPS, VA and TN.



1. Panel Type IPS (In-Plane Switching).
IPS screen, I think probably most familiar to her eyes. Because most of the time we went to the mall to see this on the TV hanging on a brand. For the benefit of IPS is the most prominent. "Broad view" to 178-degree screen that allows this kind of advantage over other types of screens in the viewing position. Whether a corner. Rates of distortion is a little much, but he is the drawbacks of IPS in terms of the "black" (black-level) may not play as good as S-PVA.


This compares to the side. The IPS screen with the VA.


The IPS is popularly called the strong (Hard Panel) of the family referred to as the VA or soft (Soft Panel).
If I rubbed my finger up the screen, VA will not be a watermark.

Type of Panel IPS was developed by different companies.

- Super-IPS (S-IPS).
The company originated in 1998 by Hitachi, which aims to improve the quality of the screen is better than conventional IPS LCD Response Time in the lower and the colorful display. Currently being produced by the two giants of the industry, LG and Philips and the LG monitor is a TV screen with their own points of sale with a view to reaching them.


I see a picture of my S-IPS screen pixel.
That the pixels are stacked chevrons. In a side view of the good.

- Horizontal IPS (H-IPS).
Another type of screen that was developed in IPS. In order to fix the light leakage along the edges of the screen in the corner and straight. The purple tones and edit images in perspective and reduce the Noise as well, but this makes the H-IPS screen, with a view to narrow down.


The arrangement of the H-IPS pixel is shown here.
- IPS-alpha (Panasonic).
Panel Type IPS-alpha is really being developed from the Panel, known as IPS-Pro it is today, the Panasonic has applied to the LCD TV / LED TV of the advantages of the Panel of this kind is the subject of Contrast. Ratio Color Space or higher and wider color space. As a result, the colors are full and more natural. Panel PVA and ASV as bringing together, without the disadvantages of a narrow view.

Two. Screen Vertical Alignment (VA).
If the screen is IPS, TN and VA, the most distinctive feature of the VA, it was black dark, or to the Contrast Ratio is high for the screen, VA, it would not escape the view that less IPS, but it is. A good example is a TN in the dark. The detail with less. If it is not sitting in the middle of the screen. But it is out in vibrant colors.


I compare it to the Panel VA and TN.
The left VA is black than black on the right side of TN.

- S-PVA (Super Patterned Vertical Alignment).
Panel Form S-PVA is one of the most widely used (developed from the Panel and MVA), which currently has the Samsung and Sony to the market by the Panel 8 Bit More (8 bit enables the color. the 256 level in the first part of a 10 Bit color display with up to four times the 1024 level in more than one color), the advantages of S-PVA is shown in black. To the dark dimension. Response Time, and was developed to lower it.

- ASV (Axially Symmetric Vertical Alignment).
This Panel was developed by Sharp with the claim that a large screen at the same point of view. Which is marketed under the name "Advance Super View", but basically it was developed from the screen itself is based on VA.

3. Panel is TN (Twisted Nematic).
To the Panel a TN or Twisted Nematic to share in most markets, with the advantages of 2 that is the decision to buy the consumer that is "cheap" and "The Response Time is low" is. The price was not considered a major factor. The most common LCD TV models in the middle to lower part of the Response Time, it will cause no problem to see the animation. But all that comes with it is great. Narrow viewing angle. Rates of distortion and color than IPS and VA screens that are only 170 degrees horizontally and vertically to 160 degrees only.
