Problems solved by technology

[0002] On the one hand, the existing polarized LED three-dimensional display technology is to set left-handed and right-handed polarizing films on adjacent rows / columns of the display device, and the pixel points of the corresponding LED display screen are also set for adjacent rows / columns. Pixels for the left eye and pixels for the right eye. Compared with the 2D resolution, the stereoscopic resolution of this solution is only reduced to 1 / 2 of the original in the vertical / horizontal direction, but there is no reduction in the horizontal / vertical direction. Therefore, this This imbalance reduces the quality of the stereoscopic image; on the other hand, the existing polarizing film is generally obtained by laminating a half-wave plate on the surface of the circular polarizer, and then punching, peeling and filling with glue. The production efficiency is low. The cost is high, or different left and right rotating polarizers are attached to the pixels of the LED display, the bonding efficiency is low and the bonding accuracy is difficult to guarantee

Abstract

The invention relates to the technical field of LED three-dimensional display, in particular to a polarizing LED three-dimensional display screen, a polarizing film and a manufacturing method thereof.The polarizing film comprises a linear polarizer and a phase difference plate arranged on the linear polarizer. The phase difference plate forms an optical rotation array in an optical alignment mode, the optical rotation array comprises left-handed polarized light and right-handed polarized light, and the left-handed polarized light and the right-handed polarized light are adjacent and continuous in the diagonal direction. According to the polarizing film, an optical rotation array is formed in an optical alignment mode, the precision and the manufacturing efficiency of the optical rotationarray are improved, and the manufacturing cost is reduced. Because the left-hand polarized light and the right-hand polarized light in the optical rotation array are adjacent and continuous in the diagonal direction, the reduction amplitudes of the three-dimensional resolution in all directions are consistent, a better 3D display effect is achieved, and the picture quality is improved.
