Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to a flexible liquid crystal display screen that can be bent to display uniformity. Background Technology

[0002] Flexible screens, also known as flexible OLEDs, have been successfully mass-produced. This success not only greatly benefits the manufacturing of next-generation high-end smartphones, but also has a profound impact on the application of wearable devices due to their low power consumption and bendability. In the future, flexible screens will be widely used as personal smart terminals continue to penetrate the market.

[0003] When existing flexible LCD screens are subjected to bending forces during use, the liquid crystal material at the corresponding bending point will flow rapidly, resulting in a lack of liquid crystal material at the bending point for display. This causes uneven display or no display at all, which cannot meet the actual use needs. In addition, some existing flexible LCD screens lack corresponding auxiliary support devices after bending, which may cause the flexible LCD screen to break, reducing the performance.

[0004] A flexible liquid crystal display screen that can be bent to display uniformity is proposed in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a flexible liquid crystal display screen that can be bent to display uniformly, in order to solve the problems of existing flexible liquid crystal displays, where the display screen lacks liquid crystal material at the bending point when subjected to bending force during use, and also lacks support after bending.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible liquid crystal display screen that can be bent to display uniformity, comprising a display screen housing, a base plate, and a flexible outer plate fixedly installed on one side of the front of the display screen housing, wherein a support base is fixedly connected to the bottom of the base plate;

[0007] A flexible substrate is fixedly installed on one side of the inner side of the display screen housing, and liquid crystal material is filled between the flexible outer plate and the flexible substrate.

[0008] Also includes:

[0009] A blocking pad is fixedly connected to the side of the flexible substrate near the flexible outer plate. The blocking pad is bent and is evenly distributed in multiple layers. A material inlet is formed between two adjacent blocking pads.

[0010] The base plate is rotatably connected to the top center of the base plate, and a top plate is threaded to the upper outer side of the main screw. A vertical rod is fixedly connected to the top of the base plate, a side rod is fixedly connected to one side of the vertical rod, and a side block is fixedly connected to the side of the side rod away from the vertical rod.

[0011] The top and bottom of the side block are symmetrically slidably mounted with sliders, and a clamping plate is fixedly connected to the side of the slider away from the side block. A fitting plate is slidably mounted inside the slider.

[0012] Preferably, the barrier pad is located between the flexible outer plate and the flexible substrate, and there are no fewer than three layers of barrier pads, with no fewer than six barrier pads in each layer.

[0013] Preferably, two vertical rods are symmetrically arranged, and both vertical rods are slidably connected to the top plate, while the side rods are fixedly connected to the middle of the outer side of the vertical rods.

[0014] Preferably, the top and bottom surfaces of the side block are provided with sliding grooves, an auxiliary spring is fixedly installed inside the sliding groove, the slider is slidably connected to the sliding groove, and the end of the slider away from the clamping plate is fixedly connected to the auxiliary spring.

[0015] Preferably, the outer side of the side block is threaded with a clamping bolt, the number of which is the same as the slider, and the clamping bolt passes through the side block and abuts against the slider.

[0016] Preferably, the slider is internally threaded with an adjusting screw, and the adjusting screw is rotatably connected to a bonding plate on the side near the display screen housing.

[0017] Preferably, there is at least one adjusting screw, and the bonding plate is a long strip plate or a square plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The specific details are as follows:

[0019] 1. By setting up a flexible outer plate, a feed port, liquid crystal material, a blocking pad, and a flexible substrate, when the display screen housing is bent, the display screen housing drives the flexible substrate to bend, which in turn puts pressure on the liquid crystal material at the bend. The liquid crystal material flows between the flexible outer plate and the flexible substrate. It is blocked by the blocking pad, so that the liquid crystal material at the bend will not flow much. The feed port realizes a small part of the liquid crystal material transfer, compensates for the pressure, and avoids the problem that excessive pressure can easily damage the flexible display screen.

[0020] 2. By setting up a main lead screw, top plate, side blocks, sliders, clamping plates, adjusting screws, and bonding plates, the operator rotates the main lead screw, which limits the vertical rod to the top plate. The rotation of the main lead screw adjusts the height of the top plate, thereby clamping and fixing the display screen housing in conjunction with the base plate. By loosening the clamping bolts, the slider is pulled to move inside the slide groove. The auxiliary spring assists the movement of the slider until the upper and lower sliders drive the clamping plates respectively, clamping the top and bottom surfaces of the vertical rod, thus completing the positioning and clamping of the vertical rod. This method is suitable for vertical rods of different heights. When bending the sides of the vertical rod later, the sides of the vertical rod will move away from or towards the bonding plate. By turning the adjusting screw, the bonding plate is moved, allowing the bonding plate to be pressed tightly against the bent vertical rod again. This facilitates support for the bent vertical rod, avoids unstable bending adjustments, and reduces damage from bending. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a flexible liquid crystal display screen that can be bent to display uniformity, including a display screen housing 1, a base plate 3 and a flexible outer plate 2 fixedly installed on one side of the front of the display screen housing 1, and a support base 4 fixedly connected to the bottom of the base plate 3.

[0030] A flexible substrate 8 is fixedly installed on one side of the inside of the display screen housing 1, and liquid crystal material 6 is filled between the flexible outer plate 2 and the flexible substrate 8.

[0031] A blocking pad 7 is fixedly connected to the side of the flexible substrate 8 near the flexible outer plate 2. The blocking pad 7 is bent and is evenly distributed in multiple layers. A feed inlet 5 is formed between two adjacent blocking pads 7.

[0032] The barrier pad 7 is located between the flexible outer plate 2 and the flexible substrate 8. There are no fewer than three layers of barrier pad 7, and no fewer than six barrier pads in each layer.

[0033] When the display housing 1 is bent, the display housing 1 causes the flexible substrate 8 to bend, which in turn causes the liquid crystal material 6 at the bend to be under pressure. The liquid crystal material 6 flows between the flexible outer plate 2 and the flexible substrate 8. It is blocked by the blocking pad 7, so that the liquid crystal material 6 at the bend will not flow much. The feed port 5 realizes a small part of the liquid crystal material 6 to compensate for the pressure and avoid the problem that excessive pressure can easily damage the flexible display.

[0034] Among them, the top center of the base plate 3 is rotatably connected to the main screw 9, the upper outer side of the main screw 9 is threaded to the top plate 10, the top of the base plate 3 is fixedly connected to the vertical rod 11, one side of the vertical rod 11 is fixedly connected to the side rod 12, and the side of the side rod 12 away from the vertical rod 11 is fixedly connected to the side block 13.

[0035] There are two vertical rods 11 symmetrically arranged, and both vertical rods 11 are slidably connected to the top plate 10. The side rods 12 are fixedly connected to the middle of the outer side of the vertical rods 11.

[0036] A slider 16 is symmetrically slidably mounted on the top and bottom of the side block 13. A clamping plate 17 is fixedly connected to the side of the slider 16 away from the side block 13. A bonding plate 20 is slidably mounted inside the slider 16.

[0037] The operator rotates the main screw 9, which limits the top plate 10 to the vertical rod 11. The rotation of the main screw 9 adjusts the height of the top plate 10, thereby clamping and fixing the display screen housing 1 in conjunction with the base plate 3. By loosening the clamping bolt 18, the slider 16 is pulled to move inside the slide groove 14. The auxiliary spring 15 assists the movement of the slider 16 until the upper and lower sliders 16 drive the clamping plate 17 respectively, clamping the top and bottom surfaces of the vertical rod 11, thus completing the positioning and clamping of the vertical rod 11. This method is suitable for vertical rods 11 of different heights and sizes.

[0038] The top and bottom surfaces of the side block 13 are provided with sliding grooves 14. An auxiliary spring 15 is fixedly installed inside the sliding groove 14. The slider 16 is slidably connected to the sliding groove 14. The end of the slider 16 away from the clamping plate 17 is fixedly connected to the auxiliary spring 15.

[0039] The side block 13 is threaded with a clamping bolt 18. The number of clamping bolts 18 is the same as that of the slider 16. The clamping bolt 18 passes through the side block 13 and abuts against the slider 16. The slider 16 is threaded with an adjusting screw 19. The adjusting screw 19 is rotatably connected to a bonding plate 20 on the side near the display screen housing 1. There is no less than one adjusting screw 19. The bonding plate 20 is a long strip plate or a square plate.

[0040] When the vertical rod 11 is bent on both sides, the two sides of the vertical rod 11 will move away from or closer to the bonding plate 20. By turning the adjusting screw 19, the bonding plate 20 is moved so that the bonding plate 20 can be pressed against the bent vertical rod 11 again, which facilitates the support of the bent vertical rod 11, avoids unstable bending adjustment, and reduces bending damage to the vertical rod 11.

[0041] Working principle:

[0042] Before using this flexible LCD screen that can be bent to display uniformity, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, the operator rotates the main screw 9, which limits the vertical rod 11 to the top plate 10. The top plate 10, together with the bottom plate 3, clamps and fixes the display screen housing 1. Then, the operator loosens the clamping bolt 18 and pulls the slider 16 to move until the upper and lower sliders 16 respectively drive the clamping plate 17 to clamp the top and bottom surfaces of the vertical rod 11, thus completing the positioning and clamping of the vertical rod 11. When the display screen housing 1 is bent, the display screen housing 1 causes the flexible substrate 8 to bend, which in turn causes the liquid crystal material 6 at the bend to be under pressure. The liquid crystal material 6 flows between the flexible outer plate 2 and the flexible substrate 8 and is obstructed. The pad 7 blocks the flow of liquid crystal material 6 at the bend, preventing excessive flow. The feed port 5 allows for a small transfer of liquid crystal material 6, compensating for pressure and preventing damage to the flexible display screen due to excessive pressure. When bending the two sides of the vertical rod 11 later, the two sides of the vertical rod 11 will move away from or closer to the bonding plate 20. By turning the adjusting screw 19, the bonding plate 20 is moved, allowing the bonding plate 20 to be pressed tightly against the bent vertical rod 11 again. This facilitates support for the bent vertical rod 11, avoids unstable bending adjustment, and reduces bending damage to the vertical rod 11.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
