Problems solved by technology
[0014] The manufacture of the brightness-enhancing integrated polarizing film / optical film structure and manufacturing method of the present invention is mainly based on the system combination model to overcome the poor matching of the overall optical effect after the combination of the traditional polarizing film and the brightness-enhancing film, resulting in a decrease in the overall penetration. The degree of polarization is only contributed by the optical mismatch of the polarizing film. The polarization and transmittance of different film layers are re-matched and integrated to produce an overall polarization and transmittance higher than that of the polarizing film combined with the brightness enhancement film, and it has reflection Light effect, the brightness-enhancing integrated polarizing film / optical film structure of the present invention is combined and matched, and the primary and secondary light penetration performance will be completely obtained without loss of penetrating light intensity

Embodiment Construction
[0032] When the light passes through two superimposed polarizing film layers, it is thicker than the thickness of a single polarizing film layer. The increase in the penetration thickness increases the absorption and polarization, but loses the light transmittance. When two polarizing films are superimposed, in addition to the basic film layer problem, there is also the problem of the optical axis alignment of the two film layers. When the polarized light generated by the first layer of polarizing film enters the second layer of polarizing film, due to the optical axis alignment The deviation angle will cause part of the light intensity to be absorbed, resulting in a decrease in light transmittance. Therefore, although the combination of two polarizing films can increase the degree of polarization, it sacrifices precious light transmittance, which is undoubtedly a great harm to the display industry where light transmittance is very important.
