[0006] Preferably, an L-shaped plate is fixed at the upper end of the second gear turntable, and bolt posts are fixed at the left, right, upper, and lower positions of the L-shaped plate. A rubber plate is sleeved on the outer wall of the bolt post, and a nut is sleeved on the outer wall of the bolt post.

[0007] Preferably, the nut rotates along the outer wall of the bolt post via the threaded structure on the inner wall, and fits against the outer end face of the rubber plate.

[0008] Preferably, the second gear turntable drives the L-shaped plate to rotate, the base plate rotates at the upper end of the second gear groove, the L-shaped plate places the MicroLED display screen at the upper end, and the rubber plate is attached to the left and right ends of the MicroLED display screen.

[0009] Preferably, the socket plate is angle-adjustable at the inner side of the support frame, and the handle is pulled outward to disengage the insertion post from the insertion hole.

[0010] Preferably, the insertion post disengages from the insertion hole, allowing the socket plate to rotate. The socket plate rotates around the fixed shaft as a central axis. Pulling the handle outward stretches the stainless steel spring, causing the stainless steel spring to accumulate a reaction force.

[0014] 1. This device clamps the MicroLED display screen using an L-shaped plate, a rubber plate, bolts, and nuts. The support frame rotates the L-shaped plate via a first gear turntable at the bottom. A connecting plate adjusts the angle of the L-shaped plate from the inside of the support frame. Simultaneously, a second gear turntable rotates the MicroLED display screen again from the top of the connecting plate. By adjusting the angles of the two gear turntables and the connecting plate, the L-shaped plate can be adjusted to multiple angles, thus making the measurement more accurate.

[0015] 2. Multiple insertion holes are distributed at the lower left end of the socket plate. When adjusting the angle of the socket plate, pull the handle outward to disengage the insertion post from the insertion hole. At the same time, the tension causes the stainless steel spring to generate a reaction force. At this time, the socket plate rotates around the fixed axis. After adjusting to the appropriate angle, release the stainless steel spring and insert the insertion post into the corresponding insertion hole. In this way, the angle of the socket plate can be quickly adjusted. Attached Figure Description

[0026] The utility model provides, for example Figure 1-6 The device shown is a viewing angle testing device for a MicroLED display screen. It includes a base plate 1, a first gear groove 13 is provided inside the base plate 1, and a first gear turntable 2 is installed at the upper end of the base plate 1 through the first gear groove 13. A support frame 3 is fixed at the upper end of the first gear turntable 2, a fixing shaft 14 is fixed at the inner side of the support frame 3, a sleeve plate 9 is sleeved at the inner side of the support frame 3, and the fixing shaft 14 is sleeved inside the sleeve plate 9. A plurality of insertion holes 12 are provided at the left end of the sleeve plate 9. A handle 4 is installed at the left end of the support frame 3. An insertion post 16 for insertion into the insertion hole 12 is fixed at the upper and lower right end of the handle 4. A stainless steel spring 15 is fixed at the middle of the handle 4. The other end of the stainless steel spring 15 is fixed to the fixing shaft 14. A second gear groove 11 is fixed at the upper end of the sleeve plate 9, and a second gear turntable 10 is sleeved at the upper end of the second gear groove 11.

[0027] The base plate 1 is installed on the upper part of the work platform by bolts. The MicroLED display screen is placed on the upper part of the L-shaped plate 8. The two rubber plates 7 are attached to the left and right ends of the MicroLED display screen. The nut 5 is rotated to make it fit tightly to the left and right ends of the rubber plates 7, thus completing the clamping of the MicroLED display screen. The first gear turntable 2 and the second gear turntable 10 can both rotate. At the same time, the angle of the socket plate 9 can be adjusted. During the rotation, the changes in brightness, color and contrast of the display screen at different angles are measured by optical sensors.

[0028] like Figure 4 and Figure 5 As shown, an L-shaped plate 8 is fixed at the upper end of the second gear turntable 10. Bolt posts 6 are fixed at the left, right, upper, and lower positions of the L-shaped plate 8. A rubber plate 7 is sleeved on the outer wall of the bolt post 6. A nut 5 is sleeved on the outer wall of the bolt post 6. The nut 5 rotates along the outer wall of the bolt post 6 through the threaded structure on the inner wall and fits against the outer end face of the rubber plate 7. The second gear turntable 10 drives the L-shaped plate 8 to rotate. The base plate 1 rotates at the upper end of the second gear groove 11. The L-shaped plate 8 places the MicroLED display screen at the upper end, and the rubber plate 7 fits against the left and right ends of the MicroLED display screen.

[0029] The first gear turntable 2 and the second gear turntable 10 can be rotated by external force, and after the external force is removed, the first gear turntable 2 and the second gear turntable 10 remain at their respective angles.

[0030] like Figure 3 and Figure 6 As shown, the socket plate 9 can be angled at the inner position of the support frame 3. Pulling the handle 4 outward causes the insertion post 16 to disengage from the insertion hole 12. The disengagement of the insertion post 16 from the insertion hole 12 allows the socket plate 9 to rotate. The socket plate 9 rotates with the fixed shaft 14 as the central axis. Pulling the handle 4 outward stretches the stainless steel spring 15, causing the stainless steel spring 15 to accumulate reaction force. The first gear turntable 2 is fixed at a right angle to the support frame 3. The first gear turntable 2 can rotate at the inner position of the base plate 1 by external force control. The base plate 1 has through holes at the four corners of the upper end. The base plate 1 is installed at the upper position of the work platform by bolts and through the through holes.

[0031] Multiple insertion holes 12 are distributed at the lower left end of the socket plate 9. When adjusting the angle of the socket plate 9, pull the handle 4 outward to disengage the insertion post 16 from the insertion hole 12. At the same time, the tension causes the stainless steel spring 15 to generate a reaction force. At this time, the socket plate 9 rotates around the fixed shaft 14 as the center axis. After adjusting to the appropriate angle, release the stainless steel spring 15 and insert the insertion post 16 into the corresponding insertion hole 12. In this way, the angle of the socket plate 9 can be quickly adjusted.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
