Nowadays the domestic electronic component industry market is huge, especially LED and LCD has been widely used, such as mobile phones, TVs, watches, remote controls, refrigerators, microwave ovens, humidifiers, and so on. But when many companies choose the display screen, how should they distinguish between LED screen and LCD screen? Which one is better?
The following is a brief introduction to the differences between LCD and LED, I hope it will helpful for your project.
The difference between LED and LCD is mainly reflected in brightness, color, contrast, viewing angle, screen appearance, maintenance cost, application range, service life, energy consumption, environmental protection, etc.
Brightness
The reaction speed of a single element of the LED display is 1000 times that of the LCD screen, and its brightness is more advantageous than that of the LCD screen. The LED display can also be illuminated under strong light and is suitable for low temperatures of minus 40 degrees .
Color
The color gamut of LCD screens can generally only reach 70%. The color gamut of the LED display can reach 110%.
Screen
The large LED screen has a good experience, can be seamlessly spliced, and the display effect is consistent. The LCD mirror has serious reflections, so after splicing and using for a period of time. Due to the different attenuation levels of the LCD screen, the consistency is different, which will affect the look and feel.
Maintenance cost
The maintenance cost of the LED display is low. Once the LCD liquid crystal display leaks, the entire screen must be replaced. The LED display only needs to replace the module accessories.
Application scope
The application range of LED display is wider than LCD display. It can display all kinds of text, numbers, color images and animation information. It can also play color video signals such as TV, video, VCD, DVD, and more importantly, it can use multiple The display screen is broadcasted online. The LCD display has a huge advantage at close range and a small screen.
Use energy consumption
When LCD is turned on, the entire backlight layer is turned on, and it can only be fully turned on or fully turned off, which has high power consumption. Each pixel of the LED works independently and can light up some pixels individually, so the power consumption of the LED will be lower.
Service life
The LED display screen can generally support about 100,000 hours, and under normal circumstances, it can be used for decades; while the LCD screen is generally 60,000 hours.
Backlight
LED display backlight: power saving (compared to CCFL power saving 30%~50%), high price, high brightness and saturation. CCFL backlight: Compared with LED backlight power consumption (still much more power saving than CRT), it is cheaper.
Environmental protection
The LED display backlight is more environmentally friendly than the LCD screen. The LED display backlight is lighter in weight and consumes less fuel during transportation. LED screens are more environmentally friendly than LCD screens when they are disposed of, because LCD screens contain trace amounts of mercury. The longer life span also reduces waste generation.
Appearance
The LED display screen uses light-emitting diodes as its basis, and its display can be made thinner compared to LCD liquid crystal screens.
Contrast
At present, the known high-contrast LCD display is 350:1, but in many cases, it cannot meet various needs, but the LED display can reach higher and more widely used.
Viewing angle
The angle limit of the LCD display is very large, which is a very lively and headache. As long as the deviation angle is slightly larger, the original color cannot be seen, or even nothing. The LED can provide a viewing angle of up to 160°, which has great advantages.
Which kind of displays would you like to try? I think you should choose according to your project and requirements. If you have any question about the TFT LCD screen, please advise your needs and we will help you find the suitable one.
