The LCD display screen is smaller in size and lighter in weight
The traditional CRT display device needs to have a vacuum picture tube inside and an electron gun at the tail end because it uses picture tube skills to image, so that its length is generally more than 30 cm, then the volume of the whole display is of course larger. For example, the LCD display selects liquid crystal data, and then uses the corresponding imaging skills to complete the display intention. It is not necessary to install a picture tube inside the display device. The volume is of course small, and the volume is relatively light.
LCD display screen has a larger relative display area
LCD Display's facial image principle and the difference between traditional CRT renderers, the scale indicated by it is the visible area of practice,
while the traditional CRT Visualizer is constrained by the visible skill, therefore, the marked scale is smaller than the appearance area of the fluorescent screen.
The LCD display screen has zero radiation and no shine
Because of the selection of liquid crystal materials, the LCD display does not need to select the electron beam during operation, therefore, there is no problem that static electricity and radiation affect vision. CRT display device uses cathode picture tube for imaging, and the electron beam inside it will generate a lot of static electricity and radiation when it moves, and the faster the electron beam runs, the greater the radiation, and the human body will use it for a long time, it will cause harm to eyes and skin, and cause problems such as myopia and skin allergy.
LCD display screen has low power consumption and strong anti-interference ability
CRT display device has power consumption of display screen in addition to circuit and display power consumption, the LCD liquid crystal display is mainly backlight and circuit power consumption, and the power consumption of its display screen can be ignored. Because the liquid crystal display is not like the CRT display, which uses picture tube and electron gun to image, it is unnecessary to consider the high radiation effect brought by the electron beam emitted by the progressive electron gun, however, the brightness is only obtained through the backlight emitted by the fluorescent tube, thus having a stronger anti-interference ability. Even in an environment where light is relatively concentrated, it will also be well displayed.
The picture quality of the LCD display screen is higher
The signal transmission of the LCD liquid crystal display device adopts the digital method, which is to directly input countless word signals from the graphics card, it will not constitute the loss of signal and the picture quality is better. The traditional CRT display device chooses the imitation method, and the signal output of the display card chooses the imitation method, which may constitute the loss of the image in the transmission process, resulting in the decline of the picture quality.
