A polarizer and its construction method

Abstract

The invention discloses a polaroid and a construction method thereof. The polaroid comprises an upper support layer, a lower support layer and a polarized layer arranged between the upper support layer and the lower support layer. The upper support layer or the lower support layer is provided with a phase difference of 1 / 2 lambda, wherein the lambda is the wavelength since the upper support layer or the lower support layer is stretched. The direction in which the upper support layer or the lower support layer is stretched is perpendicular to the direction of the absorption axis of the polaroid body. Compared with the prior art, the warping problem of the polaroid can be effectively solved; on the premise that the normal function of the polaroid is achieved, thickness of the polaroid will not be increased and penetration rate of the polaroid is not reduced; and furthermore, with the construction method, there is no need to change the manufacturing procedures and cost of the current polaroid, so the construction method has quite high promotion value.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a polarizer and a construction method thereof. Background technique [0002] With the continuous development of the display industry, thinner and lighter liquid crystal display devices have gradually become a development trend. With the reduction of product thickness, the thickness of LCD panels has also developed from the mainstream 0.5mm in the past to 0.3mm and 0.25mm. Some LCD panel manufacturers have even focused on developing 0.1mm LCD panels. In the near future, thin and light panels will become the mainstream. [0003] However, the thinner and lighter liquid crystal panels also have the possibility of panel bending. For example, in some liquid crystal panel structures, it is necessary to attach a polarizer on the surface of the liquid crystal panel. In the natural state and under the conditions of high temperature and high humidity or alternating temperature and h...
