LCD liquid crystal with LED liquid crystal difference in where?

LED is only a classification, that is, light-emitting diodes (as a result of the backlight, so here refers specifically to the white light emitting diode). LED technology is relatively simple, but according to the arrangement of the LED backlight is divided into two types of side entry and the side, the side of the TV is very thin, but the screen brightness is slightly uneven, power. Straight down type of LED is slightly thick, but the backlight is uniform, can be carried out in the area of control light, the higher the contrast. LED backlight technology for CCFL backlight longer, more wide color gamut, compared to CCFL no obvious shortcomings, has gradually become the mainstream.

LCD Chinese literal translation LCD display, LED Chinese literal translation light-emitting diode. From the name can be seen, LCD refers to the imaging technology, LED is the lighting technology.

　　
　　LCD is a big classification, such as liquid crystal display technology, through the liquid crystal molecules of optically active color, specific technology and according to the different liquid crystal molecules, the electrode arrangement is divided to many sub technology, such as STNTFTAVIPS and essence of the same are use LCD technology, but results are slightly different, such as the STN is very low power but less color is not true, TFT color very real but viewing angle small.

Liquid crystal display also has its own unique advantages, it uses a strict sealing technology will come from the drive circuit of a small number of electromagnetic waves in the display, and the general monitor in order to distribute the heat, we must make the internal circuit and air contact, so that the electromagnetic wave generated by a large number of ground out "leak".
