Abstract

The invention discloses a crystal ball axial measuring method, comprising the following steps: S1: setting a backlight station, a crystal ball station and a polarizer station, the backlight station is provided with a backlight, and the crystal ball station A crystal ball is provided, and the polarizer station is provided with a polarizer; S2: The polarizer station is set above the backlight station, and the polarizer is located on the upper surface of the backlight; S3: Set the crystal ball station above the polarizer station, and the crystal ball is located on the upper surface of the polarizer; S4: observe the inside of the crystal ball, there is an aperture inside the crystal ball, and there is an arc in the aperture line; S5: The direction indicated by the arc in the aperture is used to judge the axial direction of the polarizer. The detection efficiency is high, and the effect is intuitive and obvious, which ensures that the direction of the polarizer is correct when it is attached to the liquid crystal display.

Description

[0001] method field [0002] The invention relates to the technical field of polarizer axial measurement, in particular to a crystal ball axial measurement method. Background technique [0003] The basic structure of the polarizer includes PVA in the middle and two layers of TAC. In the field of liquid crystal display manufacturing, the polarizer is the basic part of the liquid crystal display. It is easy to cause waste of materials and low work efficiency in the process. [0004] At present, a simple, convenient and efficient detection method is needed in the aspect of polarizer axial detection. Contents of the invention [0005] In order to overcome the above disadvantages, the object of the present invention is to provide a method for measuring the axial direction with a crystal ball, which can simply and efficiently detect the axial direction of the polarizer. [0006] In order to achieve the above object, the technical solution adopted in the present invention is: th...
