[0026] Working principle: Interactive display includes the following methods: Interactive display 1: When the first folding end 3 drives the double folding display screen 5 to fold forward at an angle of 60° at both ends, and the second folding end 4 drives the triple folding display screen 6 to fold backward at an angle of 120° at both ends, and the double folding display screen 5 is folded and covered, the display mode is that the three display screens of the triple folding display screen 6 are interactively displayed in an isosceles triangle shape separately, and the double folding display screen 5 is not displayed. Fig.12 .

[0027] Interactive display 2: When the second folding end 4 drives the three-fold display screen 6 to expand forward horizontally at 120° angles at both ends to form a large display screen, and the double-folding display screen 5 is still folded into two separate display screens, the display mode is that the three-folding display screen 6 expands a large display screen and the two separate display screens folded into the double-folding display screen 5 are interactively displayed as a large and two small three-screen display screen, see attached Fig.13 .

[0028] Interactive display three, when the second folding end 4 first drives the three-fold display screen 6 to expand forward horizontally at 120° at both ends to form a large display screen, and the first folding end 3 then drives the double folding display screen 5 to expand horizontally at 60° at both ends to form another large display screen, the display mode is that the three-fold display screen 6 expands horizontally to form a large display screen and the folding display screen 5 expands horizontally to form another large display screen, and the two large display screens are horizontally aligned for interactive display, refer to the attached Fig.11 .

[0029] Interactive display 4, when the second folding end 4 first drives the three-fold display screen 6 to expand forward horizontally at an angle of 120° at both ends to form a large display screen, and the first folding end 3 then drives the double-folding display screen 5 to expand horizontally at an angle of 60° at both ends to form another large display screen, and then the second folding end 4 drives the three-folding display screen 6 to swing back and forth at an angle of 60° again, the display mode is that the double-folding display screen 5 is horizontally expanded into a large display screen and the three-folding display screen 6 is folded back into three separate display screens, and the four display screens of one large and three small are interactively displayed in a trapezoidal shape, refer to the attached Fig.14 .

[0030] It should be noted that after the double folding display screen 5 and the triple folding display screen 6 in the above interactive displays one to four are combined with each other to form a variety of special-shaped surfaces, the control unit 7 is operated by the operation panel 9 to realize the interactive display of the double folding display screen 5 and the triple folding display screen 6 after folding or unfolding to form a variety of special-shaped surface display screens.

[0031] In addition, after the double-folding display screen 5 and the triple-folding display screen 6 are performing interactive display of special-shaped surfaces, the isosceles triangle frame 21 can be driven to rotate through the rotator 23, so that the double-folding display screen 5 and the triple-folding display screen 6 can perform dynamic rotation of multiple screens when performing interactive display of special-shaped surfaces to prevent viewing blind spots. When the rotator 23 rotates, the operating frame 8 needs to turn to the right to prevent the double-folding display screen 5 and the triple-folding display screen 6 from colliding with the operating panel 9 during dynamic rotation.

[0032] In addition, the unfolding method of the first folding end 3 is that the telescopic device 3433 retracts forward, driving the double-row rack 3431 to slide forward on the fixed slide 3432, and through the engagement of the two semicircular gear plates with the double-row rack 3431, the first push-pull component 341 and the second push-pull component 342 are synchronously swung backward. At this time, the Kara slider 3414 will slide in the Kara slide groove 322, so that the third movable frame 311 and the fourth movable frame 312 are synchronously swung backward on the hinge shaft 313 to be horizontally aligned.

[0033] In addition, the second folding end 4 is unfolded in such a way that the motor 444 on the second driving end 44 drives the driving gear to rotate, and the driving gear is engaged with the arc-shaped rack 4433 and moves on the arc-shaped tooth path 4432, driving the main shaft 441 to rotate on the bearing 442, and the bearing 442 is nested on the left end of the fixed frame 41, so that the first movable frame 42 swings forward on the left side of the fixed frame 41, and the third driving end 45 drives the second movable frame 43 to swing forward on the right side of the fixed frame 41 in the same way, so that the fixed frame 41, the first movable frame 42, and the second movable frame 43 swing into horizontal alignment.

[0034] In addition, when the first movable frame 42 and the second movable frame 43 are folded backwards, the semi-open display screen groove 421 will fit onto the left and right display screens after the double-folding display screen 5 is folded forwards, preventing the rear sides of the first movable frame 42 and the second movable frame 43 from colliding with the left and right display screens after the double-folding display screen 5 is folded forwards.
