Claim Text:
1. A device comprising: a transparent bearing platform for bearing the liquid crystal display panel to be detected; a first polarizer, positioned over the transparent bearing platform; a second polarizer, positioned under the transparent bearing platform; a backlight source, positioned below the second polarizer, wherein light emitted from the backlight source is capable of arriving at the first polarizer after passing through the second polarizer and the transparent bearing platform; a first transparent electrode layer, provided over the transparent bearing platform; a second transparent electrode layer, provided under the transparent bearing platform; and a signal loading unit, electrically connected to the first transparent electrode layer and the second transparent electrode layer, for loading an electric signal to the first transparent electrode layer and the second transparent electrode layer, so that an electric field is generated between the first transparent electrode layer and the second transparent electrode layer, liquid crystal molecules of the liquid crystal display panel to be detected on the transparent bearing platform are deflected under control of the electric field; wherein the first transparent electrode layer is a first transparent glass substrate on which a transparent conductive film is coated; an area of the first transparent glass substrate is larger than an area of the liquid crystal display panel to be detected; and wherein the second transparent electrode layer is a second transparent glass substrate on which a transparent conductive film is coated; an area of the second transparent glass substrate is larger than an area of the liquid crystal display panel to be detected.
