Polaroid and display device

Abstract

The invention relates to a polaroid and a display device. The polaroid comprises a protective layer, an optic uniaxial optical film layer and a polarization layer; the optic uniaxial optical film layer is arranged on the protective layer, an unusual optical refractive index of the optic uniaxial optical film layer is greater than the refractive index of the protective layer; the optic uniaxial optical film layer comprises a platy part and multiple prism parts arranged at one side of the platy part and arranged at intervals; multiple prism parts are stored in the protective layer, wherein eachof the prism part is a triangular prism structure of a triangular pyramid structure; when multiple prism parts are the triangular prism structures, one side of each prism part clings to the platy part, and when multiple prism parts are the triangular pyramid structures, a bottom surface of each prism art clings to the platy part; and the polarization layer is laminated at one side, far away from the prism parts, of the platy part. The above polaroid not only can improve the visual angle color cast, the panel penetration rate is relatively good.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer and a display device. Background technique [0002] The current large-size display panels include LCD (Liquid Crystal Display, liquid crystal display) panels and OLED (Organic Light-Emitting Diode, organic light-emitting diode) panels, etc., wherein the LCD panels include VA (Vertical Alignment, vertical alignment) liquid crystal panels and IPS ( In-Plane Switching (in-plane switching) liquid crystal panels, etc. Compared with IPS liquid crystal panels, VA liquid crystal panels have the advantages of higher production efficiency and lower manufacturing cost, but in terms of optical properties, they have more obvious optical properties than IPS liquid crystal panels. Defects in nature, especially large-size panels require a larger viewing angle for commercial applications. The brightness of VA-type LCD panels rapidly saturates with voltage at large viewing angles. Th...

The brightness of VA-type LCD panels rapidly saturates with voltage at large viewing angles. color cast problem

[0003] The way of VA-type liquid crystal technology to solve the viewing angle deviation is to divide the sub-pixels of R (red), G (green), and B (blue) into primary and secondary pixels, so that the overall large viewing angle brightness is closer to the front view as the voltage changes. In order to solve the problem of angular misalignment by giving different driving voltages to the primary and secondary pixels in space, it is often necessary to redesign metal wiring or switching elements to drive the secondary pixels, resulting in the sacrifice of the transparent opening area and affecting the panel transmittance.
