In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 1, in an embodiment of the present invention, a display module is provided, which includes an LED light emitting screen 100 and a polarization component 200 attached to a light emitting surface of the LED light emitting screen 100, wherein the polarization component 200 includes a polarizer 210 and a liquid crystal layer 220 stacked on top of each other, and the polarizer 210 is located between the LED light emitting screen 100 and the liquid crystal layer 220.
The embodiment of the utility model provides a display module's 3D shows the principle as follows:
after the light exits from the LED panel 100, the light passes through the polarizer 210 of the polarizer assembly 200 to form a light beam with a first polarization direction, and then exits through the liquid crystal layer 220. While two situations are encountered when light is output through the liquid crystal layer 220:
in the first case, when the light passes through the liquid crystal layer 220, the liquid crystal layer 220 is in the power-off state, the polarization direction of the light is not changed, and the light beam still exits in the first polarization direction;
in the second case, the liquid crystal layer 220 is in the energized state, and the polarization direction of the light passing through the liquid crystal layer 220 is changed from the first polarization direction to a second polarization direction perpendicular to the first polarization direction.
In order to form a 3D display effect, in practical use, the liquid crystal layer 220 may be controlled by a controller or the like to be repeatedly switched between an on state and an off state at a certain frequency, so that the polarization direction of light may be repeatedly changed, thereby realizing switching of a broadcast picture between a first picture corresponding to a first polarization direction and a second picture corresponding to a second polarization direction. When the switching speed is fast to a certain degree, the human eyes may misunderstand that the two pictures are played simultaneously. When watching the display module, the viewer can receive two groups of pictures through the left and right eyes by wearing the polarized glasses, and then synthesize a three-dimensional image through the brain.
For a better understanding of the above principles, we will now illustrate:
at T0At the moment, the liquid crystal layer 220 is in the power-off state, and at the moment, the light is emitted in the first polarization direction, so that the display module displays a first picture in the first polarization direction; at T0At time + a, the liquid crystal layer 220 is adjusted to be in the power-on state, and at this time, the light is emitted in the second polarization direction, so that the display module displays a second picture in the second polarization direction; at T0At +2a, the liquid crystal layer 220 adjusts the power-back state, and the display module displays a first picture in the first polarization direction; at T0At +3a, the liquid crystal layer 220 is turned back to the energized state, and the display module displays a second picture … … with a second polarization direction
Thus, the first picture and the second picture can be alternately displayed. The adjustment of the switching frequency can be achieved by adjusting the interval (i.e., the size of a) at which the first picture and the second picture appear. When a is sufficiently small, the human eye can receive a plurality of first pictures and a plurality of second pictures within 1 second, thereby mistaking that the first pictures and the second pictures are seen simultaneously.
The embodiment of the utility model provides a display module adopts LED luminescent screen 100 as backlight module, compares ordinary backlight module, and display module's luminance effectively improves, and the visual angle is bigger simultaneously. The polarization assembly 200 may be composed of only the polarizer 210 and the liquid crystal layer 220, which are stacked, and has a simple structure. In summary, the display module provided by the embodiment has a simple structure and high brightness.
