Problems solved by technology

[0005] The current 3D image display screens are all designed for a single stereoscopic imaging method. If consumers use a 3D display screen suitable for the polarization method, they cannot watch the film source of the cylindrical lens grating method; It is a 3D display screen suitable for the cylindrical lens grating method, but it is impossible to watch the polarized film source, which brings inconvenience to consumers

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the three-dimensional naked-view polarizing display screen of the present invention includes a display screen 1 , a polarizing film 2 and a lenticular lens grating film 3 . Wherein, the display screen 1 is a common display screen for displaying two-dimensional images, such as an LCD display screen, a plasma screen, and the like. In order to minimize the influence of the drop in brightness of the output image caused by the film sticking on the viewing effect, the display screen 1 preferably adopts a high-brightness display screen, such as an LED display screen.

[0014] One side of the polarizing film 2 is closely attached to the surface of the display screen 1 , covering the entire display area of ​​the display screen 1 , and the back side of the cylindrical lens grating film 3 is closely attached to the other surface of the polarizin...

Abstract

The invention discloses a stereoscopic glasses-free polarized display screen, which comprises a display screen body, a polarized film and a lenticular lens grating film, wherein one face of the polarized film is arranged on the surface of the display screen body; and the back surface of the lenticular lens grating film is arranged on the other face of the polarized film. The polarized film and the lenticular lens grating film, which cover a display area, are arranged on the surface of the display screen body, so a consumer can watch lenticular lens grating method video source and can watch a polarization method video source through the stereoscopic glasses-free polarized display screen, and multiple video choice opportunities are obtained.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a display screen for stereoscopic display. Background technique [0002] Polarization method and lenticular lens grating method are commonly used stereoscopic imaging methods. [0003] Cinema projections use the polarization method. Through two projectors, the two sets of films captured by the two cameras are projected synchronously, so that the two slightly different images are superimposed on the screen. A polarizer is installed in front of each projector. From the light emitted from two projectors, after passing through the polarizer, it becomes polarized light. The polarization directions of the polarizers in front of the left and right two projectors are perpendicular to each other, so the polarization directions of the two beams of polarized light produced are also perpendicular to each other. These two beams of polarized light are projected onto the screen and then refle...
