The color calibration device 100 includes a cover assembly 10 having a first magnetic member 13 and a color calibration assembly 20 having a second magnetic member 23. The cover assembly 10 and the color calibration assembly 20 are detachably fixed together by the magnetic attraction between the first magnetic member 13 and the second magnetic member 23. To perform color calibration, the cover assembly 10 is separated from the color calibration assembly 20, and calibration is performed using the color calibration assembly 20. After calibration is complete, the cover assembly 10 is placed over the color calibration assembly 20.

[0028] Please refer to Figure 3 and Figure 4 The cover assembly 10 includes a lower cover 11, the first magnetic component 13, a dustproof pad 14 and a foot pad 16.

[0032] The number of the first magnetic member 13 can be one or more. It is understood that when there is only one first magnetic member 13, those skilled in the art can set the size, shape, and position of the first magnetic member 13 according to actual needs so that the first magnetic member 13 and the second magnetic member 23 attract each other, allowing the cover assembly 10 to reliably cover the color calibration assembly 20. For example, the first magnetic member 13 can be configured as a ring or semi-ring shape that circumferentially adapts to the lower cover 11 and is located at the edge of the lower cover 11. When there are multiple first magnetic members 13, they can be arranged in an array, a ring, or a random arrangement between the first lower cover 111 and the second lower cover 113, as long as the cover assembly 10 is reliably covered by the color calibration assembly 20.

[0045] The second magnetic member 23 may also be a magnet or an electromagnet. In this embodiment, the second magnetic member 23 is a magnet, and is magnetically arranged corresponding to the first magnetic member 13.

[0046] The shape, size and number of the second magnetic component 23 can be the same as or different from the shape, size and number of the first magnetic component 13. As long as the two correspond to each other, magnetic attraction can be generated to achieve detachable fixation of the cover assembly 10 and the calibration assembly 20. No specific limitation is made here.

[0047] The second magnetic member 23 can be embedded, inlaid, or adhered to the first upper shell 211 and / or the second upper shell 213 to be fixed between the first upper shell 211 and the second upper shell 213.
