How to identify the LED display screen, how to distinguish LCD and LED correctly? 1. The viewing angle of the LED LCD screen is relatively large
The image will not become very dim when viewed from the side, and will even be exactly the same as the film negative, while the general LCD screen will change color. 2. The response speed is very fast
When the image is moving, there will be no smear. When a general LCD screen processes a dynamic picture, the more dynamic the smear will be, the more obvious the smear will be, and the more blurred it will be.
3. Higher brightness
The LED LCD screen is very bright, much brighter than ordinary LCD screens, and it can be seen clearly even in the sun. 4. Screen thin
The general LED screen is much thinner than the general LCD screen. Which is better, led or lcc

Which one is better, led or lcd? From the difference between lcd and led, we can summarize:
1. Both LCD and LED have the advantages of each county
LCD has the advantages of high brightness and suitable for colorization; while LED has the advantages of low power consumption, long life, and small size. 2. LCD and LED also have disadvantages
LCD drive voltage is relatively high, the thickness is relatively large, and the power consumption is also high; LED dimming is difficult. 3. Led has replaced led (CCFL backlight)
CCFL backlit LCD is a more popular product before. At this stage, most LCDs are backlit by LEDs.
