[0028] like Figure 4-7 As shown, this example can achieve the effect that the OLED flexible screen 101 is effectively supported by the rubber plate 206 and the multiple trapezoidal blocks 205 when it is bent.

[0029] The flexible display screen includes a flat plate 201, a plurality of triangular grooves 202 are provided in the middle of the flat plate 201, the plurality of triangular grooves 202 divide the middle of the flat plate 201 into a plurality of trapezoidal blocks 205, a rubber plate 206 is bonded to the upper side of the flat plate 201, and the OLED flexible screen 101 is bonded to the upper side of the rubber plate 206, and the plurality of triangular grooves 202 on the flat plate 201 enable the middle of the rubber plate 206 to be bent through the plurality of triangular grooves 202, thereby enabling the OLED flexible screen 101 to be effectively supported by the rubber plate 206 and the plurality of trapezoidal blocks 205 when being bent, thereby preventing the OLED flexible screen 101 from easily leaving marks after being bent.

[0030] like Figure 6-7 As shown, this example can achieve the effect of connecting the left and right parts of the flat plate 201 and the plurality of trapezoidal blocks 205 into one.

[0031] Since the front sides of the left and right parts of the flat plate 201 are both provided with protrusions 204, the front sides of the multiple trapezoidal blocks 205 are both provided with protrusions 204, and the rubber strips 203 are connected to the multiple protrusions 204 by rivets, the left and right parts of the flat plate 201 and the multiple trapezoidal blocks 205 are connected as a whole by the rubber strips 203 to prevent the flat plate 201 from falling apart.

[0032] like Figure 6-7 As shown, this example can achieve the effect that the elastic plate 401 can restore the flat plate 201 to its original state through its own elastic force.

[0033] Since the limit sleeves 403 are welded to the left and right ends of the lower side of the flat plate 201, the left and right ends of the elastic plate 401 are respectively inserted into the two limit sleeves 403, a boss 404 is fixed in the middle of the elastic plate 401, and compression springs are fixed on the left and right sides of the boss 404, and the other ends of the two compression springs are respectively fixed on the two limit sleeves 403. The elastic plate 401 itself is straight. When the flat plate 201 is bent, the elastic plate 401 can restore the flat plate 201 to its original shape through its own elastic force. The two compression springs on the elastic plate 401 give the same elastic force to the two limit sleeves 403 respectively, so that the elastic plate 401 always remains centered between the two limit sleeves 403.

[0034] like Figure 6-7 As shown, this example can achieve the effect of preventing the elastic plate 401 from escaping from the limiting sleeve 403 .

[0035] Since both left and right ends of the elastic plate 401 are welded with blocks 402, both left and right ends of the lower side of the rubber plate 206 are welded with inclined legs 208, and the lower ends of the two inclined legs 208 are welded with cylinders 207, the flat plate 201 can be supported by the inclined legs 208 and the cylinders 207, and can still be supported when the flat plate 201 is bent; the two blocks 402 can prevent the elastic plate 401 from detaching from the limiting sleeve 403.

[0036] like Figure 6-7 As shown, this example can achieve the effect that the two hanging rods 301 can slide left and right between the corresponding two bars 303 respectively.

[0037] Since bars 303 are fixed on both the front and rear sides of the left part of the flat plate 201, bars 303 are fixed on both the front and rear sides of the right part of the flat plate 201, each bar 303 is provided with a slide groove 302, two hanging rods 301 are arranged on the left and right, and the two ends of each hanging rod 301 are respectively slidably connected to the corresponding slide groove 302, so that the two hanging rods 301 can slide left and right between the corresponding two bars 303.

[0038] like Figure 4-7 As shown, this example can achieve the effect of making the OLED flexible screen 101 always fit with the rubber plate 206.

[0039] Since connecting strips 102 are bonded to both ends of the left and right ends of the OLED flexible screen 101, each connecting strip 102 is provided with a hanging ring 103, and the hanging ring 103 is hung on the hanging rod 301 on the corresponding side. When the two hanging rods 301 slide away from each other, the two connecting strips 102 are driven to move away from each other, and then the OLED flexible screen 101 is tightened through the two connecting strips 102, so that the OLED flexible screen 101 is always in contact with the rubber plate 206.

[0040] like Figure 6-7As shown, this example can achieve the effect of setting the OLED flexible screen 101 tautly.

[0041] Since each of the hanging rods 301 is welded with a sliding bar 305, the two sliding bars 305 are respectively slidably connected to the two fixing sleeves 306, and the two fixing sleeves 306 are respectively welded to the left and right ends of the lower side of the flat plate 201, and the ends of the sliding bars 305 are welded with stop pins 307. The sliding bars 305 are welded with arc spring rods 304, and the other ends of the arc spring rods 304 are welded to the fixing sleeves 306. The two arc spring rods 304 respectively give the two sliding bars 305 a force to slide outward on the fixing sleeves 306, so that the two hanging rods 301 always have an elastic force to move away from each other, thereby tightening the OLED flexible screen 101.

[0042] like Figure 8 As shown, this example can achieve the effect of driving the OLED flexible screen 101 to bend.

[0043] Since fixing parts 503 are fixed on the left and right ends of the lower side of the flat plate 201, each fixing part 503 is provided with a long hole 502, the two ends of the screw 501 are respectively inserted into the two long holes 502, and the two ends of the screw 501 are inserted with pads 505. The left and right ends of the screw 501 are respectively threaded with a nut 504, and the two nuts 504 are rotated to press the two pads 505 respectively, so that the two pads 505 are close to each other, and then the two fixing parts 503 are pressed close to each other through the two pads 505, thereby driving the flat plate 201 to bend through the multiple triangular grooves 202 thereon, and then driving the OLED flexible screen 101 to bend.

[0044] A flexible display manufacturing device includes a workbench 601, wherein support columns 602 are fixed at the four corners of the lower side of the workbench 601, and the front and rear ends of the workbench 601 are vertically slidably connected to portal frames 603, and the lower end of each portal frame 603 is fixed to a bottom bar 608, and a hydraulic cylinder is fixed on the bottom bar 608, and the movable end of the hydraulic cylinder is fixed to the lower side of the workbench 601, and a vertical column 607 is fixed to the lower side of the workbench 601, and an L-shaped frame 606 is vertically slidably connected to the vertical column 607, and the L-shaped frame 606 is driven to slide by the hydraulic cylinder, and the upper part of the L-shaped frame 606 is slidably connected to a T-shaped frame 605 in the front and rear directions, and a plurality of triangular knives 604 are fixed to the ends of the T-shaped frame 605 from left to right, and the T-shaped frame 605 is driven to slide by the hydraulic cylinder.

[0045] like Figure 9-10 As shown, this example can achieve the effect of producing a flexible display screen.

[0046] The flat plate 201 can be placed on the upper side of the workbench 601, and then the gantry 603 on the rear side is used to press the flat plate 201 on the workbench 601, and then the T-shaped frame 605 and the triangular knife 604 are driven to cut the flat plate 201, and the L-shaped frame 606 can slide vertically on the vertical column 607, and then the height of the multiple triangular knives 604 can be adjusted, and then a plurality of triangular grooves 202 can be processed on the front of the flat plate 201, and then the flat plate 201 is horizontally turned 180 degrees, and a plurality of triangular grooves 202 are processed on the flat plate 201 again, so that the multiple triangular grooves 202 processed twice penetrate the flat plate 201 from front to back, and then the two gantry frames 603 are driven to press on the workbench 601, and then the flat plate 201 and the multiple trapezoidal blocks 205 thereon are fixed, and then the rubber plate 206 is bonded to the upper side of the flat plate 201, and then the OLED flexible screen 101 is attached to the upper side of the rubber plate 206, and then a flexible display screen is produced.
