LCD advertising machine is usually said to be the LCD advertising machine, the English name: ADVERTISING LCD DISPLAYER. TFT-LCD, for example, the principle of LCD is by the backlighting light source in the polarizing plate, the light in the light through the polarizing plate, will be polarized, the polarization of the light will be passed through the liquid crystal, because of the liquid crystal molecules in the arrangement of electrode voltage, so the liquid crystal is affected by the voltage generated. Because the liquid crystal molecules are arranged in such a way that the voltage generated by the electrodes is affected, the liquid crystal can change the angle of polarization of the polarized light, and the intensity of the light coming out of the different polarization angles will be different, and the intensity of the light will be different, and then after the red, blue, and green elements of the color filters are passed through, a variety of different brightnesses and different colors of the elements will be displayed, and then finally, through the various elements of the paintings can be composed of a variety of images and graphics that are visible to the naked eye.
With the popularity of advertising machines and the popularity of plasma, LCD and other flat panel display devices, network streaming media technology, the development of the system architecture, but has been through several generations of change, initially by the display and DVD player or PC, after the introduction of network technology technology, dedicated network media player to replace the traditional pure DVD or PC playback form, the function has become richer, Applications have also become more diversified.
