Embodiment Construction

[0025] figure 2 It is a schematic diagram of an apparatus for inspecting an alignment film according to a preferred embodiment of the present invention.

[0026] Please refer to figure 2 , the detection equipment of the alignment film of this embodiment includes a detection chamber 200 , a steam generator 204 and a strong light 208 .

[0027] Wherein, the detection chamber 200 is made of a solid frame, and a black curtain 202 is also covered around the solid frame. Airflow interference is blocked outside.

[0028] The steam generator 204 is placed in the detection chamber 200 , and an alignment film test piece 206 to be tested is placed above the steam generator 204 so that the steam generated by the steam generator 204 can atomize the alignment film test piece 206 . Wherein, the alignment film test piece 206 has undergone a grinding process, so many grooves have been formed on the surface of the alignment film test piece 206 . The steam generator 204 is further connected ...

Abstract

In the invention, a testing piece of oriented film is placed in a detecting chamber. Next, a steam generator is utilized to atomize the testing piece of oriented film. Then, with atomized testing piece of oriented film being irradiated by strong light, whether there are abnormal phenomena on testing piece of oriented film is viewed by visual method directly.

Description

technical field [0001] The present invention relates to a method and device for inspecting an alignment film, and in particular to a method and device for directly visually inspecting an alignment film of a Liquid Crystal Display (LCD). Background technique [0002] Liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range. Therefore, they have been widely used in medium and small portable TVs, mobile phones, video recording Consumer electronics or computer products such as computers, notebook computers, desktop monitors, and projection TVs, and gradually replace cathode ray tubes (Cathode Ray Tube, CRT) to become the mainstream of displays. [0003] A liquid crystal display is mainly composed of two substrates and a liquid crystal layer arranged between the two substrates. Moreover, an alignment film is usually arranged on the surfaces of the two substrates (the surface i...
