What is MEMC technology? What TVs are available on the market?

MEMC (Motion Picture Quality Compensation) technology,General TVs are60Hz This is under the PAL system Foreign standards are generally 50Hz 120Hz Frequency doubling is generally the name of domestic brands It just improves the image scanning frequency If you say that the solution to tail 120Hz is not absolute, I personally think it has something to do with the response time MEMC is based on an image processing technology of the American Taiding chip There's nothing to talk about,If you plan to buy a TV,I suggest you don't let people fool you These things are just selling points, and they don't have much practical meaning (I'm doing this) If you buy a joint venture, you can choose Samsung, Sharp, and domestic can choose Hisense, don't forget that you get what you pay for, and when you choose, you will become Remember that good things are never cheap!

Most TVs on the market have MEMC technology, MEMC: Chinese called motion compensation. Almost every time manufacturers talk about image quality processing, it is the first thing to mention.

However, we have to reveal that MEMC is not a new black technology. This technology, developed by the Americans, has been adopted by Japanese color TV manufacturers for a long time. It's just that most of them were used in high-end TVs at that time(This point"High-end"It was grabbed by some manufacturers,But it's opportunistic,It's all high-end TVs more than ten years ago,Can it be counted now),And in recent years, most of the products of traditional TV manufacturers will basically use this technology。

Hope mine can help you.

First of all, playing games on mobile phones, it has little to do with you often coming to Guangzhou, but if you go to Guangzhou from a cold place, you should pay attention to changing a coat (shell) for your mobile phone in time, and secondly, the main reason, your mobile phone memory or performance is too poor to support you** and play this game, the game has high requirements for the performance and speed of the mobile phone, just like we use the computer to play games, but also to configure a high-performance assembly machine, not to mention the mobile phone. It is recommended that you clean up the apps that are not commonly used on your phone, release the memory, make your phone run as fast as possible, and take a look at your phone's network, if it is wifi to see how the network speed is, if it is poor, it will also cause the mobile game to freeze, if it is 4G to see how the signal is, if the signal is not good, it will affect the network speed and will also cause such a situation, next time if this situation occurs again, the fast way is to kill the process, and then try to enter again.

In the mid-to-high-end products of the LCD market, such a function is usually included, MEMC image stabilization, which is also the most commonly overlooked function, and if you really focus on the viewing experience of TV, especially friends who are keen on blockbusters and ball games, this is an essential feature.

What is MEMC?

A standard LCD TV refreshes 60Hz per second, which is enough to quickly eliminate flickering and create a motion illusion from a series of still images. In fact, most** sources sent to your monitor arrive at the standard rate of 30 frames per second, and each frame is repeated by the TV to reach a total rate of 60 frames.

In most cases, the 60Hz refresh rate is enough to meet the needs of most people, and it may be difficult for you to find out what kind of difference there will be at a higher refresh rate, despite this, when it comes to the motion model shooting back to paste, not every pair of eyes and every brain's perception is consistent, some viewers can perceive motion blur from the standard 60Hz LCD display, and this motion blur will be easier to perceive when ** sports blockbusters or ball games.

To reduce blurring, most mid-to-high-end LCD monitors.

Use to become MEMC (Motion Estimation and Motion Compensation.

to compensate between each frame, and the end result is that there will be an extra frame between every real frame.

And with the development of technology, now MEMC motion compensation is not only that, the TV is actually not 120Hz, but increased by 4 times, to achieve 240Hz, three additional frames will be inserted between each real frame, to obtain a smoother image, reduce motion blur.

In general,MEMCThe stabilization function is not a very perceptual function,But in the actual user, it will affect every viewing experience,If you like to enjoy shocking blockbusters and ball games,If you are more sensitive to visual perception,MEMC is an important feature you need to pay attention to in TV purchases。

There are 80 types of LCD TV EMMC. emmc** reads and writes need to find at least 5 wires of vcc gnd clk cmd d0. VCC GND is the best to find, if there are drawings or dismantling the PCB of EMMC, you can easily find the flying lead.

Dot. If these conditions are not available, you can look for a full row of 0 to 10 ohm resistors and signal lines near the eMMC chip.

eMMCLook at the entire row of 0 to tens of ohms of resistors and signal lines near the EMMC chip. CLK has characteristics on the PCB, there is often a small resistor in series next to the pass-and-destroy circle, and some boards also have an empty capacitor pad, and there is generally no pull-up resistor.

The CLK has a clock signal of several hundred kHz when the cavity is electrically initialized on the eMMC.

When there is data communication, a clock signal of tens of meters will appear, with an oscilloscope.

Or the frequency meter can be seen; cmd d0 generally has a pull-up resistor.

Today's smart TVs,Most of them have MEMC function,That is, picture motion compensation technology。 TV without this technology,In**The program source is24Frames or30When the picture is moving,There will be obvious image trailing、Blur and other images,Such a picture not only affects the image quality,At the same time**Long**It will also damage people's eyesight,Therefore, this function is very important to improve picture quality。

Does it matter <> 4K TV wide and thick memc: Important, smart TV.

Most of them have MEMC function punching, that is, screen motion compensation technology. TV without this technology,When the program source is24Frames or 30Frames of moving picture,There will be obvious image tailing、Blur and other images,This cautious judgment of the picture not only affects the image quality,At the same time, it will also damage people's eyesight for a long time。

This answer is suitable for Hisense75E3D, Sony KD-65X9000H brand TV models.

<> the so-called MEMC: motion estimate and motion compensation; That is, motion estimation and motion compensation, the motion picture quality compensation technology used in LCD TVs. The principle is to use a dynamic imaging system, inserting a motion compensation frame between the traditional two frames of images, and increasing the refresh rate of ordinary flat-screen TVs from 50 60Hz to 100 120Hz.

To put it simply, in fast-moving scenes such as racing cars or ball games, MEMC technology can accurately calculate and interpolate each frame of image. Let you be in ****, the picture is more smooth and no lag. LETV zero65 has it, it's expensive for a reason, and it's also a selling point.

When the amplitude of movement is relatively large, the picture will be blurry, why is there blur and shaking? This matter also starts from the ancient film standard, the ancient film was still in the film era, in order to meet the reaction time of the human eye and the cost of shooting (film was very expensive at that time), the display frame rate (the number of films displayed per second) was set at a minimum of 24Hz. But in the era of television, because TV is self-luminous, and it is a pixel scanning way to display the picture, in fact, a black picture will be inserted between the two pictures as blanking, we call it field blanking, why not here; So when we watch TV in chronology, the TV display order is:

A valid picture black point A valid picture black square, go like this. In this case, if it is still displayed in the way of 24 pictures per second, the human eye will see flickering, for this reason, the TV display frequency is set at 50Hz (Chinese TV) or 60Hz (American TV); The corresponding radio and television programs are also determined according to this frequency. Therefore, for a movie shot at 24hz, if you want to display it at 50hz, you need to insert frames.
