1. What is LCD?

 

LCD is the full name of liquid Crystal Display. There are several types of LCD, such as TFT, TFD, STN and so on, which can not locate program input points on the DLL.

 

So,Notebook LCD screen is commonly used in TFT. TFT (Thin Film Transistor) refers to thin film transistors. Each LCD pixel point is driven by a thin film transistor integrated behind the pixel point, so that it can display screen information with high speed, high brightness and high contrast. It is one of the best LCD color display devices at present, and it is now on notebook computers and desktop computers. The mainstream display device. Compared with STN, TFT has excellent color saturation, restoring power and higher contrast. It can still see very clearly in the sun, but its disadvantage is that it consumes more power and costs more.

 

2, what is LED?

 

LED is the abbreviation of light emitting diode Light EmittingDiode. LED applications can be divided into two categories: one is LED display screen; the other is LED single tube applications, including backlight LED, infrared LED and so on. Now, for the LED display, China's design and production technology level is basically in keeping with international synchronization. The LED display screen is a display device consisting of 5000 light-emitting diodes arranged in a computer configuration sheet. It is driven by low voltage scanning. It has the characteristics of low power consumption, long service life, low cost, high brightness, few faults, large viewing angle and long visual distance.

 

3. The difference between LCD display screen and LED display screen.

 

Compared with LCD display, LED display has more advantages in brightness, power consumption, visual angle and refresh rate, and has been cancelled to the navigation of the web page. Using LED technology, we can produce a thinner, brighter and clearer display than LCD.
