What is the difference between LED and LCD displays?

2019-11-12

We have often heard of LCD displays, that is, LCD displays, so there should be friends who have heard of LED displays. Do you know the difference between the two? Today I will tell you.

LED, the full name of Light Emitting Diode, we can call it a light emitting diode, and this is one of the light sources for liquid crystal displays. The colors displayed by the LED are softer, and the light at the center of the screen and the edges of the screen are almost the same. We can't feel it, and it is suitable for those white-collar workers or gamers who face the computer every day.

LCD, full name Light Crystal Display, this is called liquid crystal display, and this kind of display uses CCFL as the light source, what is CCFL? It is a cold cathode fluorescent lamp. Don't understand this if you don't understand. In short, it is different from the light source of LED. The light intensity displayed by the LCD is relatively large. If you stare at the display for a long time, your eyes will feel tired. However, because the light is strong, the colors are more vivid. This is more suitable for watching movies, chasing dramas and the like. The light in the center of the screen and the edges will slightly deviate, and the edges will look a little darker overall. Without special attention, the effect will not be great.

So which one is better? Let's make a comparison.

1. LED-based displays are thinner than LCD displays.

2. LED has longer life, lower power and environmental protection. We all know that LED lights have a long life, and of course displays are no exception. The basic life can reach 100,000 hours. If you use it continuously for 10 hours a day, you can use it for nearly 27 years. And LED is very energy-saving, everyone knows that you have bought electric lamps, which is very energy-saving and power-saving. Energy saving is about 48% than LCD, which is almost half. LED does not use mercury, everyone should know that mercury is highly toxic, if it leaks, it will cause damage to the environment. The CCFL of LCDs contains mercury.

3. LCD backlight screen has better color capability than LED

This color will be clearer for those who professionally map. Various color purity, color gradation, gray scale, etc. LED is the color performance is worse than CCFL, most professional professional graphics drawing LCD display, because CCFL color performance is better.

Don't be misled. LCD and LED displays are actually the same, because the internal light source is different, so it will cause a difference. LCD backlight and LED backlight are cold cathode tube and diode respectively.

What is the size of the LED panel?

parameter Because LED displays are based on LEDs, their light, electrical characteristics, and limiting parameters are mostly the same as those of light-emitting diodes. But because the LED display contains multiple light-emitting diodes, the following special parameters are required: 1. Luminous intensity ratio Because each segment of the digital tube has the same driving voltage, the forward current of each segment is different, so the luminous intensity of each segment is different. The ratio of the maximum value to the minimum value of the luminous intensity values of all segments is the luminous intensity ratio. The ratio can be between 1.5 and 2.3, and the maximum cannot exceed 2.5. 2. Pulse forward current If the typical forward DC working current of each segment of the stroke display is IF, the forward current under pulses can be much larger than IF. The smaller the pulse duty cycle, the larger the pulse forward current can be. size The size of the CRT display refers to the diagonal size of the picture tube. The maximum viewing area is the maximum range of graphics that the monitor can display. The size of the picture tube is usually measured by the length of the diagonal, in inches (1 inch = 2.54cm), and common are 15 inches, 17 inches, 19 inches, 20 inches and so on. The display area will be smaller than the size of the display tube. The display area is expressed by the product of length and height. Usually people also use the diagonal length of the visible part of the screen. The viewing range of a 15-inch display is about 13.8 inches, the viewing area of a 17-inch display is mostly between 15 and 16 inches, and the viewing area of a 19-inch display is about 18 inches. Display size The size of the LCD display refers to the diagonal size of the LCD panel, in inches (1 inch = 2.54cm). The mainstream ones are 15 inches, 17 inches, 19 inches, 21.5 inches, 22.1 inches, 23 inches, 24 inches and so on. Added: mainstream notebook sizes are 10.1 inches, 12.2 inches, 13.3 inches, 14.1 inches, 15.4 inches, 17 inches.

LED Light Features

LED lamps are light-emitting diodes, which use solid semiconductor chips as the light-emitting material. Compared with traditional lamps, LED lamps have the advantages of energy saving, environmental protection, color rendering and response speed. (I) Energy saving is the most prominent feature of LED lights In terms of energy consumption, the energy consumption of LED lamps is one-tenth that of incandescent lamps and one-fourth that of energy-saving lamps. This is one of the biggest features of LED lights. People now advocate energy saving and environmental protection. It is precisely because of this feature of energy saving that the application range of LED lights is very wide, making LED lights very popular. (Two) can work in high-speed switching state We usually walk on the road, and we will find that the screen or picture of each LED is unpredictable. This shows that LED lights can perform high-speed switching. However, for the incandescent lamps we usually use, this working state cannot be achieved. In ordinary life, if you switch too many times, it will directly cause the incandescent filament to break. This is also an important reason for the popularity of LED lights. (Three) environmental protection The LED lamp does not contain any heavy metal materials such as mercury, but it is contained in the incandescent lamp, which reflects the environmental protection characteristics of the LED lamp. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lights. (4) Fast response speed LED lights also have a prominent feature, which is that they respond faster. As soon as the power is turned on, the LED will light up immediately. Compared with the energy-saving lamps we usually use, the response speed is faster. When turning on the traditional light bulb, it often takes a long time to illuminate the room, and it can only turn on after the light bulb is completely heated. (5) Compared with other light sources, LED lights are "cleaner" The so-called "clean" does not mean that the surface and interior of the lamp are clean, but that the lamp belongs to a cold light source, does not generate too much heat, and does not attract insects who like light and heat. Especially in the summer, there will be a lot of bugs in the countryside. Some bugs are naturally hot, and incandescent and energy-saving lamps generate heat after being used for a period of time. This heat is exactly what the bugs like and it is easy to attract them. This will undoubtedly bring a lot of pollutants to the surface of the lamp, and the excrement of insects will also make the room dirty. However, the LED light is a cold light source and will not attract insects, so no insect waste will be produced. Therefore, LED lights are more "clean".
