Abstract

The invention provides a polaroid, a display screen device and a mobile terminal. The polaroid comprises a substrate layer, a first protection glue layer, a polarization layer, a second protection glue layer and a functional layer which are sequentially stacked, the first protection glue layer annularly coats the surface of one side of the polarization layer and is in glue joint with the substrate layer, and the substrate layer in the surrounding area of the first protection glue layer is attached to the polarization layer. And the second protection glue layer is coated on the surface of the other side of the polarization layer and is in glue joint with the functional layer. The first protection glue layer and the second protection glue layer are respectively adhered to the two side surfaces of the polarization layer so that the polarization layer is sealed by the first protection glue layer, the substrate layer and the second protection glue layer, and a waterproof effect is good. In the area surrounded by the first protection glue layer, the polarization layer is directly attached to the substrate layer, the thickness of the part of the polaroid is small so that a light and thin design can be achieved, and the polaroid is high in reliability and good in bending effect.

Description

Technical field [0001] The present disclosure belongs to the technical field of electronic devices, and involves a polarizer, a display device, and a mobile terminal. Background technique [0002] The polarizer is applied to the field of display and is used to provide polarized light. For example, a polarizer is provided in a display device such as OLED or LCD, which includes a flexible screen or a hard screen having a stable shape. [0003] In the related art, the polarizing plate is also extremely fragile material, in order to ensure the thinning design and structural stability of the polarizer, the thickness dimension and the waterproof requirement are high. Such as figure 1 As shown, the polarizing plate includes a stacked pressure-sensitive layer 104, a PVA (polyvinyl alcohol, polyvinyl alcohol) layer 101, protective glue layer 103, and functional layer 102, wherein the polyvinyl alcohol constituting the PVA layer 101 is easily soluble. Water, the protective glue layer 103 h...
