Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] see figure 1 , the invention provides a method for testing the ion content of a polarizer, comprising:

[0025] Step S1, providing a polarizer sample including a polarizing layer and a polarizing film on the opposite surface of the polarizing layer. The polarizer sample described in this embodiment is a square, specifically a sheet body of 1 cm*1 cm. This polarizer sample does not include protective film and release film.

[0026] Step S2, putting th...

Abstract

The invention provides a polaroid ion content testing method. The method comprises the following steps: putting a polaroid sample into ultrapure water according to a certain ratio; heating the ultrapure water to a first temperature and lasting a first time so as to obtain a primary ionic solution; adding ultrapure water in the same amount as that of the primary ultrapure water into the primary ionic solution; heating the ionic solution in which the ultrapure water is added to a second temperature and lasting a second time so as to obtain a sample ion solution; establishing an ionic standard substance curve and determining a standard concentration relational expression; obtaining a response value curve of to-be-detected ions in the sample ion solution by an ion chromatograph; and substituting the response value of to-be-detected ions in the sample ion solution into the standard concentration relational expression, thereby obtaining the actual ion concentration of the polaroid sample.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel manufacture, in particular to a method for testing the ion content of a polarizer. Background technique [0002] TFT-LCD (Thin film transistor-liquid crystal display: Thin film transistor-liquid crystal display) is currently the only display device that has fully caught up with and surpassed CRT in terms of brightness, contrast, power consumption, life, volume and weight. Its With excellent performance, good mass production characteristics, high degree of automation, and broad development space, it has quickly become the current mainstream product. [0003] The Cell liquid crystal panel is composed of a thin film transistor array substrate, a color filter array substrate and liquid crystal sandwiched between the two substrates. The array substrate and the color filter substrate are filmed by chemical or physical methods, and then exposed, developed, and etched to obtain the array sub...
