Like all electronic technologies, many people do not understand about the screen. For example, you or your family want to buy a flat-panel TV or monitor that faces a host of parameters: resolution, faceplate type, backlighting, etc., that sounds complicated. However, in order to buy the most suitable for their own products, or need to find out the differences of these key parameters, so we may wish to briefly understand the following.
 
Panel Type:
TN
We often say that the TN screen is actually an abbreviation for the Twisted Nematic (twisted nematic) panel. In fact, you do not have to remember this complex academic name, just remember: TN screen is the lowest cost LCD panel, the worst display, narrowest angle on it. Basically, most low-end displays use this panel.
VA
As long as the VA panel is divided into the MVA developed by Fujitsu and Samsung PVA, it is a relatively better solution than TN but still inferior to IPS's compromise solution. VA panel has a better wide viewing angle, but still belongs to the soft screen (with finger touch panel will produce ripple), response time, viewing angle, uniformity and less than IPS. This panel is usually equipped with some high-end displays.
IPS and PLS
 
IPS (left) vs. TN (right) panel differences contrast
 
There is no doubt that IPS is the best performing LCD panel with outstanding color performance, high viewing angle and lower power consumption. IPS is often referred to as a "hard screen" because of the glass outer layer on its surface. High-end TVs, cell phones, tablets, and displays are commonly available with IPS panels. As for PLS, it is Samsung's standard IPS, which has a lower cost, but is basically consistent with IPS.
LED backlight technology:
LED TV is replaced by light-emitting diode CCFL cold cathode fluorescent lamp, to achieve better lighting imaging results. However, LED backlight development is also evolving so far, so mainly for the three types, the display is not the same.
 
Direct type LED backlight:
 
Mainly in the backlight covered with LED lights, to achieve uniform lighting effects. Characterized by the fine quality, the backlight can be set to the region, that is the so-called "local control light" technology, so as to achieve a separate treatment of different colors. However, the backlight technology will affect the thickness of the television, so some ultra-thin as the selling point of the TV to another backlight technology.
 
Side-entry LED backlight:
 
Very easy to understand, side-type LED backlight is built around the LCD panel LED bulbs, illuminate the light guide plate to achieve LCD screen lighting. As the light bulb is less, so running TV makers will be more lightweight TV body design, the mainstream of the market are using thin-screen TVs are using this technology. However, due to some inherent shortcomings, can not achieve local control, the color performance is less than the direct type so well.
 
 
Quantum dot technology:
 
Recently very popular "Quantum Dots TV", in fact, is also a new type of backlight technology. It features nanocrystalline materials instead of LED light source, to achieve more pure, more vivid color reproduction backlight color, the LCD TV's color effect can be comparable to the OLED level. Therefore, the use of quantum dot technology LCD TV is also the best display in the market, the most expensive price.
So OLED?
 
As for the OLED, in fact it is a completely different type of display, called Organic Light-Emitting Diode (Organic Light Emitting Diode), and Liquid Crystal (Liquid Crystal) is completely different concepts. OLEDs feature self-lighting (no backlighting required), slim, bright colors, wide viewing angles, and the use of plastic panels mean that it can be more flexibly flexible.
There is no doubt that OLED TV is currently the best display in the market, its dark black level and color fidelity and plasma quite, without plasma limitations. However, due to the OLED technology is still starting out period, there is the problem of high cost, low yield, the size of the LCD screen is also smaller, so the price of OLED TV is very expensive. If you pursue the perfect picture quality and not bad money, LG and other brands of OLED TV is the best choice.
