Embodiment Construction

[0033] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0034] Please refer to FIG. 3A, which is a schematic side view of the structure of the polarizing plate axis vector measurement device of the present invention. The polarizing plate axis vector measuring device 3 of the present invention includes: a light generating device 31, a polarizing device 32 and a measuring and comparing device 33. The light generating device 31 can provide a light source 311, and the light source 311 can have several different wavelengths (ie, multi-color light, or white light, etc.). The polarizing device 32 is set corresponding to the light generating device 31, and can receive the light signal from the light source 311 and convert it into data that can be read. In a preferred embodiment of the present invention, the polarizing device 32 further includes: a light extraction unit 321, ...

Abstract

The invention relates to a polarizing plate axial measuring device and a measuring method. The measuring device can provide a polarizing plate to be measured, and comprises a light supply device, a polarizing device and a measuring comparing device. The light supply device can provide a light supply. The polarizing device is arranged corresponding to the light supply device and can bear the polarizing plate to be measured, and also can measure a light signal obtained after the measuring light supply passes through the polarizing plate without need to turn the polarizing plate to be measured and convert the signal into data which can be read and judged. The measuring comparing device is connected with the polarizing device through telecommunication, and at least presets a comparing data, and can receive the data provided by the polarizing device so as to make data comparison with the comparing data. Therefore, the axial deflexion angle of the polarizing plate to be measured can be quickly and accurately measured and calculated in virtue of the data provided by the polarizing device and the comparison between the data and the comparing data.

Description

Technical field [0001] The present invention relates to a polarizing plate axis vector measuring device and measuring method, in particular to a method that can quickly measure the axis of the polarizing plate to be measured without rotating the polarizing plate to be measured. Deflection angle to achieve real-time monitoring of the polarizing plate manufacturing process. Background technique [0002] Liquid crystal display (Liquid Crystal Display; LCD for short) has been widely used in various electronic information devices, such as televisions, computers, mobile phones, personal digital assistants (PDAs), and so on. The commercially available liquid crystal panels, because the liquid crystal molecules are between the solid and liquid, not only have the characteristic that the liquid is easy to flow under the action of external force, but also have the unique optical properties of the crystal, so it can use the external electric field to drive the liquid crystal alignment state....
