What are the advantages of liquid crystal display ?

An LCD is an active matrix liquid crystal display driven by a thin-film transistor (TFT), so what are the advantages of an LCD display?

1. LCD has obvious advantages in energy saving.

2. Its radiation index is generally lower than that of CRT.

3. Due to its principle, there will be no geometric distortion and linear distortion.

4. The LCD display has a large viewing area.

5. High-definition picture quality (except for some low-cost shrinkage displays).

6. Compared with CRT's, the display is several times lighter in weight, and the thickness is also several times thinner, so it is easy to move.

7. It will not cause the color distortion of the picture due to insufficient power supply.

The above is an introduction to the advantages of liquid crystal displays.

Comparison of LCD and CRT:

1. The dot spacing of CRT displays is mostly millimeters, while the pixel spacing of LCD is mostly millimeters.

2. A CRT resolution can be adjusted to a variety of resolutions, but its maximum resolution may not be the most suitable resolution. But the maximum resolution for the LCD is the best resolution. If the set resolution is less than the real resolution, the display effect will be affected.

3. The refresh rate of CRT should reach more than 75Hz to avoid flickering; Every pixel of the LCD is emitting light continuously, so there is no flickering on the LCD.

4. The viewing angle of most flat screen monitors can reach 180 degrees, while the LCD is about 120 160 degrees, once the viewing angle exceeds its actual viewing range, the color of the picture will decrease.

5. The size of the CRT display is the size of its picture tube, and the part that can be used to display the image cannot reach this size at all, but for LCD, the nominal size is basically the size of the viewing area.

6. The response speed of LCD is 16-40ms, while CRT is only 1ms.

7. Theoretically, CRT can display unlimited colors, while LCD can only display about 260,000 colors, and LCD is not as good as CRT in terms of grayscale.

8. CRT has problems in focusing, convergence, respiration effect and other aspects to varying degrees, while LCD does not, and CRT display effect is not as good as LCD.

9. CRT has radiation, while LCD does not have any radiation at all, CRT is large in size, large in weight, occupies space, LCD thickness is only a few centimeters or more than ten centimeters, small in size, light in weight, space-saving. **LCD is much more expensive than CRT. LCD is much better than CRT in terms of text performance as well as environmental friendliness.

Advantages and disadvantages of LCD:

1. The advantages of LCD, compared with CRT, LCD has low working voltage, low power consumption, 70% less power consumption than traditional CRT display, small heat dissipation, no radiation, no damage to human health, complete plane, accurate image restoration, no distortion, large viewing area, novel and diverse styles, can save a lot of space, strong anti-interference ability, sharp display characters, stable picture without flickering, and convenient screen adjustment.

2. The shortcomings of LCD, the LCD display is high, the viewing angle is small, the reaction time is slower than CRT, and there are bad pixels that cannot be repaired.

The display is different.

The viewing angle of the LCD monitor is symmetrical from left to right, while the upper and lower levels are not necessarily symmetrical. When the incident light from the backlight passes through the polarizer, liquid crystal, and orientation film, the output light has a specific directional characteristic, that is, most of the light emitted from the screen has a vertical direction. If you look at a completely white picture from a very oblique angle, you may see blacks or distorted colors.

Due to the different range of human vision, if you do not stand in the best viewing angle, you will see errors in color and brightness.

The traditional display is more delicate, but it consumes power, it is easier to hurt the eyes when it is close, the image is clearer, the image quality is better, the LCD display is more power-saving, the color and picture quality are not as good as the traditional one, and it is better for the eyes.

I don't know what era you said about traditional displays, traditional to which era! If it's a big head, then there's nothing to say!

At present, LCD displays are divided into 2 eras! One is the LCD era, the other is the LED era, and they both actually belong to LCD displays! The easiest way to tell the difference is that the LCD is thicker and heavier than the LED!

The advantage of LCD is that there is a small chance of light leakage, and the disadvantage is that the color is not high!

The advantage of LED is that the color degree is improved, and it also adds functions such as eye protection! The shortcomings are light leakage, but this normal use can't be seen, and it's not a quality problem!
