Problems solved by technology

[0003] The existing 3D-LED display technology is mainly formed by precise alignment and lamination of polarized 3D film and LED. In 3D-LED display, on the one hand, the light of the LED lamp bead is in a free scattering state, and on the other hand, the side of the matching 3D film is easy to Light leakage, resulting in light leakage at the seam position during the splicing process of 3D-LED modules, which is manifested as a white edge phenomenon
At the same time, as the LED dot pitch becomes smaller and smaller, the pitch accuracy requirements for polarized 3D film matching are getting higher and higher, and light intrusion and optical crosstalk are prone to occur at the junction of adjacent row and column phase differences, which will affect the comfort of 3D

specific Embodiment approach 2

[0029] Specific embodiment two: the following combination figure 1 and 2 This embodiment is described. This embodiment further describes Embodiment 1. There are two options for the polarizing layer 301: a circular polarizer or a linear polarizer, and the corresponding retardation layer 303 is changed, specifically:

[0030] The first type: the polarizing layer 301 adopts a circular polarizer, and the polarizing layer 301 adopts a circular polarizer;

[0031] The first retardation layer 303-1 adopts a 1 / 2 retardation layer, and the second retardation layer 303-2 is a sealing layer without retardation; or the second retardation layer 303-2 adopts a 1 / 2 retardation layer, The first retardation layer 303-1 is a sealing and leveling layer without retardation.

[0032] see figure 2 , forming a layout in which left-handed light and right-handed light are alternately arranged.

[0033] The second type: the polarizing layer 301 adopts a linear polarizer, the first retardation laye...
