The structure of indoor digital LCD display is to place liquid crystals in two parallel pieces of glass. Between the two panes of glass there are many vertical and horizontal thin wires. The rod-shaped crystal molecules are controlled in such a way that they change their direction and refract the light, regardless of whether they are electrified or not. Generate screen.

What are the structural features of indoor digital LCD displays?
The feature of indoor digital LCD displays is that the liquid crystal must be poured between two layers with thin grooves in order to function properly. The grooves on the two planes of the indoor digital LCD display are perpendicular to each other (cross at an angle of 90 degrees), that is, if the molecules are arranged on one plane in a north-south direction, the molecules on the other plane are arranged in an east-west direction and are located between the two planes. The molecules are forced into a state of 90-degree rotation. Since the light spreads along the direction of arrangement of the molecules, the light is also rotated by 90 degrees as it passes through the liquid crystal. However, when a voltage is applied to the liquid crystal, the molecules are rearranged vertically so that the light can shoot out directly without twisting.
The luminous feature of the indoor digital LCD display is that it relies on a polarization filter and the light itself. Natural light scatters randomly in all directions. The polarization filter is actually a series of increasingly thin parallel lines. The lines form a network that blocks all light that is not parallel to these lines, and the lines of the polarization filter are exactly perpendicular to the first, so that already polarized light is completely blocked. The light only penetrates if the lines of the two filters are perfectly parallel or if the light itself has been rotated to fit the second polarization filter.
The indoor digital LCD display consists of two polarized filters that are perpendicular to each other, so under normal circumstances, all incoming light should be blocked. However, since the two filters are filled with twisted liquid crystals, after passing through the first filter, the light is twisted by 90° through the liquid crystal molecules and finally passes through the second filter. If, on the other hand, a voltage is applied to the liquid crystal, the molecules rearrange themselves completely parallel, so that the light is no longer twisted, but only blocked by the second filter. In short, turning on blocks the light, and no turning on leaves the light out. Of course, the arrangement of liquid crystals in the indoor digital LCD display can also be changed so that the light is emitted when it is on and blocked when it is not on. However, since the LCD screen is almost always on, only "on" blocks the light.
