Speaking of last year's DIY market, it is really necessary to mention the chicken-end PC-side game. It can be said that the chicken-fighting game is almost a self-sustaining effort to feed a slow-moving DIY market in recent years.
However, by 2018, they will all reach May. Although chickens can still win the crown from time to time on the STEAM sales list, the number and popularity of online games have clearly declined.
Some time ago, some friends had given me an ammunition screen for him because of eating chicken. However, as the enthusiasm receded, I believe that many of my friends are just like him and have not played much now. The attention of eSports is still lower than the tradition of audio and video entertainment. demand.
The VA panel and TN panel are the most used in the eSports screen. Then we will take this opportunity to chat with you about the most used panel for the eSports panel: What are the advantages and disadvantages of the TN panel, the VA panel, and the IPS panel that everyone sees most? Is it worth buying?
This time we talk about performance, talk about daily experience.
First of all, simple science popularization of the difference between the 3 kinds of panels
Our three protagonists today are actually all The same belongs to the LCD screen camp , And we are familiar with the OLED screen is another camp, this will not be discussed today.
First of all, we know that the LCD screen itself does not emit light. It is necessary to have the LED lights on the back to brighten the screen, and the screen must be able to achieve light and dark changes. How is this achieved?
The engineers added two polarizers on the upper and lower sides of the LCD panel. The orientation of the openings of the two polarizers was inconsistent, making it impossible for the linear LED light to pass through both openings at the same time, but to pass through two layers of polarizers. Between the liquid crystal molecules guide the light to twist through, so as to achieve the purpose of displaying images.
The biggest difference between IPS, VA, and TN is that The arrangement of liquid crystal molecules is different The path that guides the light to twist is different.
When the N screen displays white, the light is guided through the horizontal spiral liquid crystal molecules, and when the display is black, the liquid crystal molecules change from the horizontal direction to the vertical direction, so that the light can not be smoothly guided through, so the TN screen It is called Twisted Nematic.
The IPS screen, when displaying white, is guided by the spiral liquid crystal molecules in the horizontal direction similar to the TN screen. However, the liquid crystal molecules do not turn in the vertical direction when displaying black, but the horizontal direction is still twisted, and the original spiral is made. Formed into layers, the light will be blocked in the upper polarizer, so IPS screen English is called (In-Plane Switching), which means to twist in the same plane.
The VA screen can roughly understand that between the IPS and the TN screen, the liquid crystal molecules are turning to a certain angle but not vertical. At present, there are mainly Fujitsu-led MVA panels and Samsung-led PVA panels, the latter being the former. Inheriting and improving, now we see that most of the products sold on the market are Samsung's VA panels.
What are the advantages and disadvantages of these types of screens?
Here we have found 3 monitors with IPS, VA, and TN screens, respectively. Their positioning is not the same. See if the actual display results are the same as the theoretical results.
Since we don't talk about performance, let's take a look at what points will affect your experience when used daily.
Gray scale: Let's talk about grayscale first. What impact does it have on daily use? In these types of screens, the TN panel is Native 6bit , while the IPS and VA panels are Native 8bit The difference between the two is the difference in the number of colors. The TN screen is 2 to the 6th power of 2.62 million colors, and the IPS and V screen is 2 to the 8th power of 16.77 million colors. The difference in the number of colors is significant.
From the grayscale graph above you can see the transition from white to black, because 8bit has more color than the 6bit panel in the middle gray area, so the perception is that the color transition is more natural, this is watching movies and watching pictures. There will be obvious feelings.
Although there are many 6bit panels that use the algorithm of the driver IC to increase the display color, the display effect is still a certain distance from the native 8bit.
(In the upper left-hand corner of the figure, the sky is full of gray shades.)
Viewing angle: Another point that affects daily use is the viewing angle of the screen. The TN screen also has congenital defects due to the arrangement of the liquid crystals.
As mentioned above, when the IPS screen displays black, the liquid crystal molecules will be twisted in the horizontal direction. Therefore, the twisted liquid crystal molecules in the vertical direction of the TN screen make the light perpendicular to the twisted liquid crystal molecules. The screen is played out, so it only has the best viewing effect when the human eye is facing the screen, and the screen will be clearly deflected when viewed diagonally.
(narrow viewing angle of TN screen is unbearable)
In comparison, both IPS and VA screens belong to the wide viewing angle screen. Most of the publicity can reach a viewing angle of 178 degrees, which is already close to 180 degrees. From the actual perspective, it can basically do.
If you are a single person, the low left and right viewing angles of the TN screen may have little effect on you. However, the viewing angles on the top and bottom of the TN screen are very poor. If you are in a dormitory and watch a movie together, you can sit on the edge of your classmates. Basically can not see.
(In addition to IPS and VA brightness reduction, color performance is also good)
Light leakage & contrast: The advantages of blowing out so many IPS screens are discussed below. Since the IPS screen adopts a horizontal liquid crystal molecular arrangement, the viewing angle is increased and the penetrability of light is also reduced, in order to achieve the same as others. The display effect will increase the brightness of the LED backlight, and increase the brightness of the backlight when the same display is black, it will be brighter than other panels, that is, the light leakage phenomenon is more serious, which is very common in the IPS screen.
