The central position is such that the positioning of the optical test device 20 is achieved. Thereafter, the first adjustment member 54 and the second adjustment member 55 of the fine adjustment assembly 50 are adjusted to adjust the relative distances of the two fine adjustment platforms 52, thereby adjusting the verticality of the optical test apparatus 20. Then, the hinge of the notebook computer 200 is removed, the screen area 220 and the button area 240 are at the same level, and the screen area 220 is placed between the limiting blocks 64 of the clamping assembly 60, and is adjusted according to the size of the screen area 220. The relative position between the plurality of stop blocks 64 in turn fixes the screen area 220. On the other hand, the button area 240 is passed between the bottom plate 62 of the clamping assembly 60 and the clamping plate 68, and the adjusting knob 69 cooperates with the through hole 674 to clamp the pressing member 672 and the clamping plate 68. The area 240 is such that the notebook computer 200 is positioned by the clamping assembly 60. Finally, the electronic control box 80 controls the first driving component 74 and the second driving component 78 to operate to drive the notebook computer 200 to achieve ±88 degrees of rotation in the Y-axis and Z-axis directions through the frame 72. Thus, the optical test device 20 can collect the light of the screen area 220 and further calculate the optical parameters of the screen of the notebook computer 200.

When the hinge of the notebook computer 200 does not need to be disassembled, the button area 240 is at an angle to the screen area 220 at this time, and the button area 240 still passes between the bottom plate 62 and the clamping plate 68. First, the clamping plate 68 is rotated, the clamping plate 68 is pressed against the button area 240, and the spacing between the resisting member 672 and the clamping plate 68 is adjusted by the adjusting knob 69, so that the clamping plate 68 and the resisting member 672 are common. The button area 240 is clamped.
