What is the difference between LED display and LCD display on the market now?

It is very likely that we watch too many ads, and we all think that LED is good.

In fact, the difference between them is not very big, please be patient and read it.

The difference between LED and LCD is only in the backlight, the panels are the same.

The merchant said this, which is somewhat deceptive.

Real LEDs are the ones we see on the big billboards on the walls.

Both of their panels are LCD, also called TN panels.

Compare it with the diode is of course good, energy-saving, environmentally friendly, small place, high brightness, and fashionable.

But it's a bit more expensive.

If you are optimistic about these two **, you still buy LED, if the difference is too much, you need LCD.

LCD is also beneficial, I think the lamp is softer, and the adjustable range is relatively high.

Understand, it's pure hand, and I don't want to copy.

Good luck.

1. Whether the display is LCD or LED.

2. LED display.

and LCD displays.

3. The difference between LED display and LCD.

4. Liquid crystal display.

Is it LCD or LED.

Liquid crystal display is the abbreviation of LiquidCrystalDisplay, the structure of LCD is to place the liquid crystal box in two parallel glass substrates, set TFT (thin film transistor) on the lower substrate glass, set up color filters on the upper substrate glass, and control the rotation direction of liquid crystal molecules through the signal and voltage changes on the TFT, so as to achieve the purpose of controlling the polarized light of each pixel and whether it is out or not to achieve the purpose of lifting and grinding.

2.Now that LCD has replaced CRT as the mainstream, it has also declined a lot and has become fully popular.

Abbreviation of English word, main meaning: led = lightemittingdiode, light-emitting diode.

It is a solid-state semiconductor device capable of converting electrical energy into visible light.

It can directly convert electricity into light.

Large-scale e-display.

The differences are as follows:

First, the principle is different.

1. LCD is to display the picture on the backlight board, and it needs a liquid crystal display unit.

2. The LED is a lattice light, and the two principles are different, resulting in different production processes, but it is difficult to say which of the two is more advanced.

Second, the clarity is different.

The screen resolution of LED can be higher than that of LCD, so that its clarity will be higher, and the more obvious difference is reflected in the mobile phone, because the pixel density of most LCD materials is lower than that of LED.

Third, the performance is different.

The color performance of the LCD screen, the anti-rotten search speed, etc., is slower than the LED, which can make the color display more accurate, and the response speed is faster, and the operation will be more sensitive.

Fourth, ** different.

The LCD screen is usually cheaper than the LED, because it has a lower production cost, and the LED screen is higher, and the experience is better.

Fifth, the applicable scenarios are different.

1. The LCD screen is suitable for occasions where the clarity is not high, and the display area of the calendar is less than 10 square meters.

2. The LED screen is suitable for occasions with high display effect requirements and very accurate color requirements.

LCD means liquid crystal display, and LCD can be subdivided into several different types of liquid crystal displays such as TFT, TFD, UFB, STN, etc. LED is the English abbreviation of lightemittingdiode. The difference between the two:

1. The luminous principle of LED and LCD is different, and the corresponding manufacturing process is also different. Specifically, LEDs are densely dotted with light-emitting diodes (LEDs) to form and display images, and the clarity of such images depends on the resolution of the light-emitting dots. LCD is composed of liquid crystal units, and this process manufacturing is mainly controlled by large manufacturers.

For example, Samsung, LG, BOE, AUO, Sharp, etc. 2. If the requirements for clarity are not high, then the LED display is very suitable, and the LCD is suitable for users who have strict requirements for clarity. 3. If the size of the screen is to be high, then the key orange LED display can meet the demand.

The LCD splicing screen display is suitable for those with a small demand area, generally less than 10 square meters. 4. In terms of the way of calculating the first formwork, the LED display is calculated by square, and the LCD is calculated by block or unit. Obviously, in terms of cost, LEDs are better [ooo

If the distance is short, it is recommended to use LCD LCD splicing screen, and if the distance is long, it is recommended to use a small pitch LED screen, but it is necessary to refer to the actual use environment.

To put it simply, the single screen size of LCD LCD splicing screen is larger, while the single screen size of LED is smaller. Therefore, the specific choice must be comprehensively considered from the user's own needs and the use environment.

LED display (LED panel): LED is the English abbreviation of light emitting diode, referred to as LED.

It is a display method that controls semiconductor light-emitting diodes, and its general appearance is that it is composed of many light-emitting diodes, usually red, and the characters are displayed by turning the lights on and off.

In order to solve the color problem of dot matrix screen, a scheme that draws on outdoor display technology is borrowed, and at the same time, the outdoor pixel reuse technology (also known as pixel sharing technology, virtual pixel technology) is transplanted to the indoor display screen.

Here we should first clarify the concept of LED screen, for home users, the so-called LED screen refers to the LCD screen with LED light source as backlight; And what really uses LEDs to display images is the large outdoor screen.

The following is for your answer, the mainstream of the LCD screen is now LED backlight, which has the advantages of high efficiency, low power consumption and long life; However, in the high-end industry, it is still the traditional CCFL backlight that accounts for the majority of the market share.

Now most of them are LED. In fact, it is mainly distinguished by the backlight mode of LCD, using LED as the backlight, with low voltage, low power consumption, high brightness and low failure rate! The old-fashioned high-voltage LCD lamp is mostly used as the backlight, which is relatively complex, and this backlight method is rarely used at present.

Economical angle LED maintenance cost is low and convenient. You just need to change the mod and you're good to go. We've used both screens before.

Sinbaco's LEDsHikvision's LCD. There are gaps in liquid crystals.

Low brightness. The lifespan is not long. High clarity.

This is relative.

1. Compared with LCD displays, LED displays have more advantages in terms of brightness, power consumption, viewing angle and refresh rate. With LED technology, it is possible to create displays that are thinner, brighter, and clearer than LCDs.

Nowadays, merchants in the market are deliberately confusing the difference between LCD and LED.

Let's put it this way, LCD itself does not emit light, but it can control the amount of light that passes through itself, and the structure is a liquid crystal between two thin layers of glass. In order to see the image, we need to add a layer of light-emitting plate behind him, which is called a backlight. In the past, the backlight of LCD displays was a fluorescent light source.

To put it bluntly, it is a very thin tube lamp, which is used as a white light source through the whiteboard, so the size is thick, the energy consumption is large, and the heat dissipation is large. The LED LCD display on the market now refers to the LCD display with LED backlight, which has the advantages of thinness, low energy consumption and low heat generation. But LEDs are only used as backlights, emitting uniform white light.

A true LED display means that there is no liquid crystal at all. Using the principle of LED luminous color and controllable light intensity, the LED display point on the display board can directly display the image. This is the future development direction of the display field, but because there are still problems in the technology, there is no specific product, and it is expected that such products will appear in thirty or fifty years.

Both can be used in some situations today, so how do you choose? What are the differences and advantages between the two? Today, we will explain it in detail to you.

The reason why LED display has been widely valued and developed rapidly is inseparable from its own advantages. It has: high brightness, miniaturization, long life, low operating voltage, low power consumption, stable performance and shock resistance.

LED display screen display screen bright color, three-dimensional sense of strong, static like oil painting, dynamic like a movie, LED development prospects are extremely broad, is currently moving towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, panchromatic direction.

The LCD splicing screen is a kind of splicing screen body that uses the splicing method of LCD display unit splicing to achieve the large-screen display effect through the splicing control software system. At present, the common splicing methods include 55-inch ultra-narrow edge LCD splicing, 46-inch ultra-narrow LCD splicing screen, 47-inch LCD splicing, 60-inch LCD splicing wall and 40-inch narrow-edge LCD splicing system.

Compared with TV and PC LCD screens, LCD splicing screens have higher brightness. The brightness of the TV or PC LCD screen is generally only 250 300cd m2, while the brightness of the DID LCD screen can reach more than 700cd m2. Because every point of the LCD retains the same color and brightness after receiving the signal, unlike the CRT, which needs to constantly refresh the pixel dots.

As a result, LCD brightness is uniform, image quality is high and flicker-free, close range**, and the picture is more delicate.

So compared with the LED display and LCD splicing screen, who is the real king of the screen display, we will see at a glance from the following aspects. Web Links.

The LED display is not limited by size, supports customization, and has bright colors, which is favored by the market now.

LCDs are backlit with tubes similar to energy-saving lamps.

LEDs use light-emitting diodes as backlights.

LED is more energy-saving, LED light is softer, closer to nature, and there is a kind of LED TV, which is directly composed of many light-emitting diodes The display screen has no backlight, this kind of TV color is more natural, and it is more energy-saving, but it is very expensive.

To put it simply, LED has lower power consumption than LCD displays, and it saves a little power, although the electricity cost saved is not enough for the price difference between the two;

LED heat dissipation is smaller, so it can be made thinner, and now the market price is not much different, think about it yourself.

LCD preparation is outdated, LED energy saving and the like are good, and the use time is long.

The current LCD TV, there is a kind of called LED TV, which refers not to use LED as a display screen, but to use LED as the backlight of the LCD panel, which is more energy-efficient. And it can be made very thin. In addition, the life of LEDs is also longer.

Another kind of real LED display refers to the display made of LED light-emitting diodes, which is usually used in large screens in outdoor and indoor public places. But the display effect is not as fine as that of liquid crystals.

LCD is liquid crystal and LED is composed of light-emitting diode screen, the principle of light is different, LED because it is composed of a small light-emitting bulb, so its response speed is fast, that is, the luminaire from light to off very fast, projection of high-speed motion picture when the tail phenomenon is better than LCD, of course, ** is higher.
