How to solve the tail of LCD TV LCD panel?

The defects of liquid crystals, but the update of technology, the problem is also overcoming.

It is recommended not to buy this kind of machine with serious tailing, it is best to buy one with 100MHz frequency doubling, and there is Sony, Sharp's machine, Sony, Sharp's machine, even if there is no frequency doubling, the tail control is good (such as Sony46V440, Sharp46gx3).

The tailing phenomenon is related to the response time of flat panel LCD, which is an important performance parameter of LCD and cannot be changed.

Sharp solves this problem with QS liquid crystal drive technology and double-speed drive technology. However, the overall effect is not as fast as the response speed of LG and Philips joint venture IPS hard-screen LCD TV. Moreover, the cost of IPS LCD screen is not as expensive as that of Sharp LCD screen.

**Approachable.

Then you buy an IPS hard-screen LCD TV,,No tailing,

IPS hard screen LCD completely get rid of tailing.

Many consumers are most worried about the problem of drag when buying LCD TVs, due to the large LCD TVs, slow response, there will be shadow phenomenon when watching some ball games, which makes people very unhappy, the author has visited some professionals in this regard, and has come to the following conclusions.

According to experts,VA soft screen was launched earlier,And LCD TVs have been usingVAsoft screen,The effect is still very good,The effect is clear,Color saturation,It's just that sometimes there will be tailing when watching dynamic pictures,This is unavoidable,And since last year, the IPS hard screen panel researched and developed by South KoreaLG Display company has come out,All the way soaring,And surpassedVASsoft screen,And is used by many manufacturers,This is also for a reason, The main advantage of IPS hard screen in dynamic clarity, accurate color reproduction, viewing angle and other aspects is mainly in the IPS hard screen. First of all, compared with the traditional soft screen LCD, the IPS hard screen has a stable liquid crystal molecular arrangement structure, and the response speed is faster, so it has super expressiveness in dynamic definition, which completely eliminates the blur and water ripple diffusion phenomenon of the soft screen LCD screen when it is subjected to external pressure and shaking, and the afterimage and trailing are eliminated during the extremely fast picture, therefore, for the aerospace, automobile, subway and other industries that are always in motion, the IPS hard screen is used to obtain the image quality without any loss. IPS hard screen panel engraves the drag problem of VA soft screen,It is also clear and smooth when watching dynamic pictures,It makes people feel great,And the heat dissipation function is good,The surface is anti-extrusion。

Finally, I would like to remind you that in the current market, VA-type panels are mixed, and it is recommended to choose products that use IPS panels such as Philips, LG, etc. It is easy and convenient to identify, just press it with your finger. In terms of quality, it is much better than the products that use Taiwanese screens.

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.

Whether it is tailed,It also has a lot to do with the reaction speed of LCD TV,The smaller the response speed,The better the effect。

2.Theoretically speaking, all display devices have the phenomenon of delayed display (tailing is one of the cases), which is caused by the characteristics of the display device, which cannot be eliminated, and can only be optimized, improved or improved;

The response time of the LCD monitor is generally between 5 and 16ms (milliseconds), and when playing games, there is often a "tailing" phenomenon due to "delayed response";

And this "delay response" generally depends on the "response time" parameter of the display (if the graphics card parameters can be enough to meet), the larger size, the "response time" of the newer product can reach or lower than 5ms, if other parameters such as "**", "interface", "other performance" and other parameters can meet the user's requirements, you can meet the requirements of use.

Personal opinion is the problem of TV itself,The tail phenomenon of LCD TV cannot be completely solved from a technical point of view for the time being。

Because the LCD TV controls the passage of light by the rotation of the liquid crystal in the LCD panel,The rotation of the liquid crystal requires a reaction time,So the picture lags behind when it expresses the state of motion,It is what we call tailing。 The lag time of LCD rotation is the response speed,With current technology,Generally, LCD TVs are between 16 25 milliseconds,The fastest can do8 milliseconds。 However, 8 milliseconds still cannot completely overcome the tailing phenomenon, especially in large action screens, the liquid crystal can still be seen.

Whereas plasma is directly luminous, there is no such problem.
