It is true that there are a lot of LCD TVs that do not perform well, which is what many of us are worried about. However, I heard that the LCD TV with a hard screen panel solves our concerns,Its screen response time is short,The response speed is fast,The picture is clear and smooth when the picture is moving,There will be no tailing。
-
LCD 22 inches and below is not trailing.
-
The TV has a tailing phenomenon, mainly because there is a problem with the decoding chip and processor.
If there is only occasional tailing, it is usually caused by the processing speed of the image processor not keeping up with the requirements of the picture, and it does not affect the normal **, which is a normal phenomenon and can be ignored.
If there is often a tailing phenomenon, and the situation is serious, affecting the normal**, it is most likely that there is a problem with the decoding chip and processor, and it is necessary to contact the after-sales service of the TV for maintenance.

This phenomenon is a "common problem" with LCD TVs (or computer monitors). The higher the contrast of the picture, the faster the movement, and the more obvious the 'tailing' phenomenon is. This is not a "disease".
When purchasing, you should pay attention to the "response characteristics --- LCD pixel response speed", the shorter the response time, the better. The general display response time is 5--2ms, and the most advanced has been developed to.

When the liquid crystal changes the image with strong contrast, it will remain due to the effect of the response speed, and it will appear as a trailing on the whole picture. Now there is a millisecond response speed of the liquid crystal, and there is basically no tailing.

To really understand the causes of LCD smearing, take a look at the logs below. However, it is not easy to understand for non-specialists.
-
TV ghosting is often caused by a low refresh rate or slow reaction time. When moving quickly on the screen, such as an athlete running, the pixels linger for a short time and have a smearing effect. This phenomenon is known as "afterimage" or "dragging", and it is especially noticeable when watching sports events and action movies.
Specifically, wall-mounted TVs or radar TVs and other products that use OLED, LCD and LED screen technology, the drag effect of virtual leather hands is mainly related to the following factors:
Refresh rate: The number of times the display is updated per second, that is, the higher the refresh rate, the reduction of the phenomenon of TV ghosting. Generally speaking, the higher the refresh rate of a TV, the better the performance of getting a smoother, clearer picture.
Response time: Also known as grayscale response time, it refers to the time it takes for the different colors of the LCD TV screen to go from black to white to black. The faster the response time, the less ghosting on the screen.
The main ways to solve the problem of TV smearing include upgrading to a higher refresh rate TV, choosing a TV with a lower grayscale response time, and using additional equipment such as a TV editor to help reduce the smearing effect.

I heard a friend say that the IPS hard screen is not easy to cause eye fatigue, which is more beneficial to eye health. These are all certified by Beijing Institute of Ophthalmology and Beijing Tongren Hospital.
In this case, players who play 3C, Dota and Shinsan are more likely to encounter, and it is rare to play ordinary battles. The reason is explained, and the upper floors do not understand nonsense. >>>More
