Difference 1. Different working methods
LED is a semiconductor light-emitting diode. The LED lamp beads are reduced to the micron level. Each tiny LED lamp bead is a pixel, and the screen panel is directly composed of this micron level LED lamp bead. LCD display is actually a liquid crystal display. Its main working principle is to stimulate liquid crystal molecules to generate dots, lines and surfaces to form a picture with the back lamp.
Difference 2. Different display brightness
The single element reaction speed of LED display screen is 1000 times that of LCD screen, so LED display screen has more advantages in brightness. Even if you look at the screen under strong light, there is no problem at all. However, high brightness is not an advantage. It is better if you watch from a distance, but it will be very dazzling if you watch from a close distance. The LCD screen emits light by refracting light. The brightness is relatively soft and does not hurt the eyes, but it is difficult to see the screen clearly in strong light. Therefore, the LED screen will be more suitable for long-distance display, and the LCD screen will be better if it is mainly used for close viewing.
Difference 3. Different display colors
In terms of color texture, LCD screen has better color, richer and more colorful picture quality, especially stronger expressive force for gray scale.
Difference 4. Different power consumption
The power consumption ratio of LED and LCD is about 1:10. Because the LCD switch means that the whole backlight layer is fully open or closed; The difference is that LED can only light up some pixels in the display screen, which is better than others in terms of power saving.
Difference 5. Different contrast
In contrast, thanks to the self luminous characteristics of LED, the contrast is better than LCD, because LCD is difficult to show pure black due to the existence of backlight layer;
