Working principle
LCD(Liquid Crystal Display) LCD Monitor
LCD is a passive display device. Its basic principle is to use the
physical characteristics of liquid crystal, liquid crystal
molecules will change the arrangement under different electric
fields. Inside the display, there is a backlight source (usually a
cold cathode fluorescent tube CCFL or an LED light bar). The light
is emitted from the backlight source and passes through components
such as a liquid crystal layer and a polarizer. When the
arrangement of the liquid crystal molecules changes, the
polarization direction of the light is changed, thereby controlling
the transmission and blocking of the light and realizing the image
display. For example, when the black part is to be displayed, the
liquid crystal molecules will adjust the arrangement to block the
light from passing through; And when the white part is displayed,
the light is allowed to pass through.
TFT(Thin - Film Transistor) Thin - Film Transistor displays
TFT belongs to active matrix liquid crystal display, which is
improved on the basis of LCD. The TFT display integrates a thin
film transistor (TFT) behind each liquid crystal pixel. These TFTs
can precisely control the state of the liquid crystal molecules at
each pixel, thereby more precisely controlling the passage and
blocking of light. By applying different voltage signals to the
TFT, the brightness and color of each pixel can be independently
controlled, achieving high-quality image display. For example, when
displaying a color image, the TFT can accurately adjust the
brightness of the red, green, and blue sub-pixels according to the
input signal to combine various colors.
