The difference between them is that the LED light can be placed on the whole panel, but the LCD light can't, so the brightness of the LED display is more uniform than that of the LCD display, and it's more realistic and vivid to see, while the LED light is more energy-saving, long service life and more durable than the LCD light. thank you.

The working principle of liquid crystal display is: under the action of electric field, the arrangement direction of liquid crystal molecules is changed to change the light transmittance of the external light source (modulation), so as to complete the electrical optical conversion. Then, the color re display in time domain and space domain is completed by using the different excitation of R, G and B primary color signals and through the red, green and blue primary color filter film.

You are also wrong. According to the backlight, there are led and CCFL backlight LCD displays (LCD stands for liquid crystal display, not backlight). If you touch CCFL backlight on the lower frame of the screen (the installation position of the driving board and the lamp), you can feel obvious heat (the lamp and the driving circuit are calorific), while the LED can't feel heat even if the screen is on for a day

The display card receives the signal and controls the voltage of the liquid crystal array through the internal coding of the display. By applying a certain voltage to the liquid crystal, the crystal presents different light refraction and reflection characteristics, so as to restore the color and graphics.

Compared with LCD display, LED display has more advantages in brightness, power consumption, viewing angle and refresh rate. The power consumption ratio of LED and LCD is about 10:1, and the higher refresh rate makes led have better performance in video, which can provide up to 160 bandwidth ° It can also play TV, video, VCD, DVD and other color video signals. Multiple displays can also be broadcast online. The single element reaction speed of organic LED display screen is 1000 times of that of LCD screen. It can be taken care of under strong light and adapt to the low temperature of minus 40 degrees/

Sharp LCD TV and sharp LED TV are both LCD TV. The difference is that the backlight of LCD is fluorescent tube, while the backlight of LED is led, so the display screen of LED TV can be thinner than that of LCD TV. At the same time, the life of LED TV is longer and the energy is saved.
