1, CRT display
is a display that uses a cathode ray tube (CathodeRayTube), which is usually one of the standard equipment of a computer. Early CRT monitors had only a small green patch, but nowadays 20-inch CRT monitors are commonplace. As the size increases, the maximum display effect of CRT displays is also improving.
LCD
2, LCD display
is a liquid crystal display, which has the advantages of thin body, small footprint, and small radiation. The working principle of LCD liquid crystal display, there are many liquid crystal particles inside the display, they are regularly arranged into a certain shape, and the colors of each side of them are differently divided into: red, green, and blue. These three primary colors can be restored to any other colors. When the monitor receives the display data from the computer, it will control each liquid crystal particle to rotate to a different color surface to combine into different colors and images. Also because of the disadvantages of such LCD screens are that the colors are not bright enough and the viewing angle is not high. At this time, if it is matched with a polarizer, it has the effect of preventing light from passing through (when no electric field is applied, the light can pass through smoothly), if it is matched with a color filter, changing the voltage applied to the liquid crystal can change The light transmittance of a certain color can also be said vividly by changing the voltage across the liquid crystal to change its transmittance (but in practice this must be matched with the polarizer).
3, LED display
Through the appropriate connection of the light-emitting diode chip (including series and parallel) and the appropriate optical structure. It can form the light-emitting segment or light-emitting point of the light-emitting display. These light-emitting segments or light-emitting points can be composed of a digital tube, a symbol tube, a rice-shaped tube, a matrix tube, a level display tube, and so on. Usually the nixie tube, symbol tube, and rice-shaped tube are collectively called the stroke display, and the stroke display and the matrix tube are collectively called the character display.
4, 3D display screen:
has now developed two major three-dimensional display technology systems that require and do not need to wear three-dimensional glasses. Traditional 3D movies have two sets of images on the screen. The audience must wear polarizers to eliminate ghost images, form parallax, and create a three-dimensional effect.
