Which is the difference between LED and LCD?-Which is better, LCD screen or LED Screen?

?

Now the domestic electronic components industry has a huge market, especially LED and LCD have been widely used, such as mobile phones, TVs, watches, remote controls, refrigerators, microwave ovens, humidifiers and so on. But when many companies choose display screens, how to distinguish between?LED screens?and LCD screens, which one is better? Shenzhen Xingyuhe Electronics Co., Ltd. is a manufacturer that has been focusing on the R&D and production of LCD screens and LCD modules for 19 years. The following is a brief introduction to the difference between LCD and LED. I hope it will be helpful.

?

The difference between LED and LCD is mainly reflected in brightness, color, contrast, viewing angle, appearance, screen, maintenance cost, application range, lifespan, energy consumption, environmental protection, etc.

?

1. Brightness

?

The response speed of a single element of the?LED display?is 1000 times that of the LCD liquid crystal screen, and its brightness is also more advantageous than that of the LCD liquid crystal screen. The?LED display?screen can also be taken care of under strong light, and it can adapt to the low temperature of minus 40 degrees. .

?

2. Color

?

The color gamut of LCD screens can generally only reach 70%. The?LED display?color gamut can reach 110%.

?

3. Screen

?

The?LED large screen?experience is good, seamless splicing can be realized, and the display effect is consistent. The mirror reflection of the LCD is serious, and the splicing will be used for a period of time. Due to the different degrees of attenuation of the LCD screen, the consistency is different, which will affect the look and feel.

?

4. Maintenance cost

?

The maintenance cost of the?LED display?is low, and the LCD liquid crystal display must be replaced once it leaks. The?LED display?only needs to replace the module accessories.

?

5. Application scope

?

The application range of the?LED?display is wider than that of the LCD display. It can display various texts, numbers, color images and animation information, and can also play color video signals such as TV, video, VCD, DVD, etc. More importantly, it can use multiple frames. The display is broadcasted online. The LCD display has a huge advantage in short distances and small screens.

?

6. Energy consumption

?

When the LCD is turned on, the entire backlight layer is turned on. It can only be fully turned on or turned off, and the power consumption is high. Each pixel of the LED works independently, and some pixels can be lighted up independently, so the power consumption of the LED will be lower.

?

8. Environmental protection

?

LED display?backlight is more environmentally friendly than LCD liquid crystal screen. The LED display backlight is lighter and consumes less fuel while shipping.?LED displays?are more environmentally friendly than LCD screens when disposed of, as LCD screens contain trace amounts of mercury. The longer life also reduces waste generation.

?

9. Viewing angle

?

The angle of the LCD display is very limited, which is a very troublesome problem. As long as the angle is slightly larger, the original color cannot be seen, and even nothing can be seen. The LED can provide a viewing angle of up to 160°, which has great advantages.

?

10. Contrast

?

The currently known relatively high-contrast LCD display is 350:1, but in many cases, it cannot meet various needs, but the?LED display?can reach a higher level and be used more widely.

?

11. Appearance

?

The?LED display?is based on light-emitting diodes. Compared with the LCD liquid crystal screen, the display can be made thinner.

?

12. Service life

?

LED displays?can generally support about 100,000 hours, and under normal circumstances, they can be used for decades; while LCDs generally last for 60,000 hours.

?

13. Backlight

?

LED display?backlight: power saving (compared to CCFL power saving 30%~50%), high price, high vividness and saturation. CCFL backlight: compared to LED backlight power consumption (still much less power than CRT), cheaper.
