For better explanation of the structure of the detecting apparatus 01, the structure of the detecting apparatus 01 will be described with reference to the X, Y, Z coordinate axis, wherein the X, Y, Z coordinate axes are perpendicular to each other.
As shown in fig. 1 and 2, the first detecting device 20 is configured to detect an offset amount of the film in the first direction, and the first detecting device 20 detects the first edge 1002a of the film to thereby detect the offset amount of the film in the first direction.

The color detected by the first detection module is different from the color detected by the second detection module, and in this embodiment, the first detection module detects the color of the film, and the second detection module detects the color of the LCD screen. When the positioning device 40 pushes the display to move towards the first direction, that is, the positioning device 40 pushes the display to move towards the direction where the first detection device 20 is arranged, and positioning is completed in the first direction, the first detection module 201 is clung to one side of the film far away from the display, the first detection module 201 can detect the color of the film, if the film occurs, the first detection module 201 and the second detection module 202 are clung to one side of the film far away from the display, that is, the second detection module 202 can detect the color of the film, and the difference exists between the color of the film and the color of the LCD screen detected by the original setting, which indicates that the offset of the first edge 1002a of the film does not meet the preset condition. For example: the LCD screen may be set to be black, the film may be set to be white, the color detected by the first detection module 201 is set to be white, the color detected by the second detection module 202 is set to be black, and when the display is positioned, only when the color detected by the first detection module 201 is set to be white and the color detected by the second detection module 202 is set to be black, the offset of the first edge 1002a of the film meets the preset condition.

In some embodiments, the first detection module 201 and the second detection module 202 are color sensors that can detect the color of the object.
It should be noted that: since the offset of the film is strictly defined in the left and right of the LCD panel, the maximum allowable offset is 0.5mm, and thus the preset condition for the offset of the film is usually set to be less than 0.5 mm.

It will be appreciated that: the distance between the first detection module 201 and the second detection module 202 is not limited to 0.5mm, but may be set to other dimensions, where the distance between the first detection module 201 and the second detection module 202 is set according to the maximum allowable offset of the actual object, for example: when the maximum offset of the film on the display screen is required to be 0.8 mm in other embodiments, the distance between the first detection module 201 and the second detection module 202 may be set to be 0.8 mm.
In other embodiments, the color sensors of the first detection module 201 and the second detection module 202 may be replaced by a proximity sensor, where the proximity sensor is a device capable of sensing the proximity of an object, and the proximity sensor may sense the object through a preset sensing distance, for example, the proximity sensor may be set to have a preset sensing distance of 0.5mm in the third direction, and the object may be sensed by the proximity sensor within a range of 0.5mm from the proximity sensor in the third direction. In some embodiments, the thickness of the film is 0.28mm, thus setting the preset sensing distance of the proximity sensor to be 0.28mm, after the display is positioned in the first direction, the film may be detected by the first detection module 201, and if the film is detected by the second detection module 202, it indicates that there is a shift of the film in the LCD screen along the first direction, and the shift of the film does not meet the preset condition. Wherein the third direction is perpendicular to the first direction and the second direction.
As for the second detecting device 30, as shown in fig. 1 and 2, the second detecting device 30 is configured to detect an offset of the first edge 1002b of the film on the LCD screen.

When the positioning device 40 pushes the display to move towards the second direction, that is, the positioning device 40 pushes the display to move towards the direction where the second detecting device 30 is arranged, and positioning is completed in the second direction, the side, away from the display, of the film is clung to the third detecting module 301, the third detecting module 301 can detect the color of the film, if the side, away from the display, of the film appears, the side, away from the display, of the film is clung to the third detecting module 301 and the fourth detecting module 302, that is, the fourth detecting module 302 can detect the color of the film, and the difference exists between the color of the film and the color of the LCD screen detected by the original setting, which indicates that the offset of the second edge 1002b of the film does not meet the preset condition. For example: the LCD screen may be set to be black, the film may be set to be white, the color detected by the third detection module 301 is set to be white, the color detected by the fourth detection module 302 is set to be black, and when the display is positioned, only when the color detected by the third detection module 301 is set to be white and the color detected by the fourth detection module 302 is set to be black, the offset of the second edge 1002b of the film meets the preset condition.
