Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, and in particular to a liquid crystal display capable of double-sided display. Background Technology

[0002] Chinese patent number CN2862090Y discloses a double-sided liquid crystal display (LCD) comprising two opposing liquid crystal display panels, two opposing light guide plates, and a double-sided light-emitting reflective sheet located between the two light guide plates. The two light guide plates and the double-sided reflective sheet are integrally formed. The two light guide plates and the double-sided reflective sheet are located between the two liquid crystal display panels. Another double-sided LCD comprises two opposing liquid crystal display panels, two opposing light guide plates, and two opposing reflective sheets located between the two light guide plates. The two reflective sheets are integrally formed with the two light guide plates, and the two reflective sheets and the two light guide plates are located between the two liquid crystal display panels. In the above-mentioned double-sided LCDs, there is no gap between the light guide plates and the reflective sheets, thereby reducing light loss.

[0003] This device can be used in the production of double-sided LCD displays. It can directly reflect light from the reflective sheet integrally formed with the light guide plate, reducing the transmission path and interface of the propagation medium and light, thereby reducing light loss. However, this device does not have an assembly structure. During the production process, it is necessary to fix the symmetrical LCD display panels separately. Traditional frames are not easy to install, so an improvement was proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that lack an assembly structure, require separate fixing of symmetrical liquid crystal display panels during production, and have traditional frames that are difficult to install. Therefore, this invention proposes a liquid crystal display that can display on both sides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a double-sided liquid crystal display, including a first frame and a second frame. A curved liquid crystal panel is fixedly installed inside the first frame, and a flat liquid crystal panel is fixedly installed inside the second frame. Thickened edges are provided at the four corners of the first frame and the second frame. L-shaped fixing grooves are provided inside the thickened edges. Fixing plates are movably engaged inside the fixing grooves. Two sets of limiting grooves are provided inside one end face of the fixing groove. The two sets of limiting grooves are respectively provided in the first frame and the second frame. Two sets of limiting blocks are fixedly connected to the inner end face of the fixing plate. The limiting blocks are movably inserted into the limiting grooves.

[0007] Preferably, the other end face of the fixing groove is internally threaded with two sets of fixing screws. The two sets of fixing screws are respectively disposed on the first frame and the second frame. The first frame, the second frame and the fixing plate are fixedly connected by the fixing screws.

[0008] Preferably, a ramp is provided at the connection between the thickened edge and the first frame and the second frame, and the first frame and the second frame smoothly transition to the thickened edge through the cooperation of the ramp.

[0009] Preferably, abutment plates are fixedly connected to the four corners inside the first frame and the second frame, and connecting rods and insertion rods are fixedly connected to the inner end faces of the two sets of abutment plates, with the insertion rods movably inserted into the interior of the connecting rods.

[0010] Preferably, control buttons are provided on one end face of both the first frame and the second frame.

[0011] Preferably, the first frame and the second frame have wire holes on the same side end face.

[0012] Preferably, the lower end faces of the first frame and the second frame are engaged and fixed with a support base.

[0013] The present invention proposes a double-sided liquid crystal display, which has the following advantages: by setting a thickened edge, a fixing groove can be opened inside it; by setting a ramp, the frame can gradually transition smoothly to the thickened edge. The thickened edge has better strength and can prevent collision damage. Then, a fixing plate is inserted, and a limiting block is inserted into the limiting groove to make the first frame and the second frame inseparable from each other. Finally, it is fixed with fixing screws, thus completing the frame assembly. This device can install liquid crystal displays inside the frames on both sides, thereby facilitating the assembly of the device and improving production efficiency.

[0014] The connecting rod and the plug-in rod can be fixed by the abutment plate. The plug-in rod and the connecting rod can be plugged in to prevent the first frame and the second frame from shifting during assembly. The control buttons can control the flat LCD panel and the curved LCD panel separately. They can be turned on individually or simultaneously as needed, which facilitates the use of the device. The support base can support the frame. The support base is locked in place after the first frame and the second frame are fixed, which is convenient for installation. The control wires of the display can be led out through the wire hole for convenient power supply connection. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7A double-sided liquid crystal display includes a first frame 1 and a second frame 2. A curved liquid crystal panel 3 is fixedly installed inside the first frame 1, and a flat liquid crystal panel 4 is fixedly installed inside the second frame 2. Thickened edges 8 are provided at the four corners of both the first frame 1 and the second frame 2. L-shaped fixing grooves 802 are provided inside the thickened edges 8, and fixing plates 9 are movably engaged inside the fixing grooves 802. Two sets of limiting grooves 803 are provided inside one end face of the fixing grooves 802, respectively located in the first frame 1 and the second frame 2. Two sets of limiting blocks 901 are fixedly connected to the inner end face of the fixing plate 9, and the limiting blocks 901 are movably inserted into the limiting grooves 803. By providing the thickened edges 8, fixing grooves 802 can be opened inside them, and then the fixing plate 9 can be engaged. The insertion of the limiting blocks 901 into the limiting grooves 803 prevents the first frame 1 and the second frame 2 from separating, thus completing the frame assembly. This device allows liquid crystal displays to be installed inside the frames on both sides, thereby improving production efficiency.

[0025] refer to Figure 1 In order to control the device, control buttons 6 are provided on one side of the first frame 1 and the second frame 2. By setting control buttons 6, the flat LCD panel 4 and the curved LCD panel 3 can be controlled respectively. They can be turned on individually or simultaneously as needed, which facilitates the use of the device.

[0026] refer to Figure 1 In order to facilitate power supply to the device, wire holes 7 are provided on the same side end face of the first frame 1 and the second frame 2.

[0027] refer to Figure 3 In order to support the frame, a support base 5 is engaged and fixed on the lower end face of the first frame 1 and the second frame 2. The engagement and fixing facilitates the installation and disassembly of the support base 5.

[0028] refer to Figure 4 In order to connect the fixing plate 9, two sets of fixing screws 902 are threaded on the inner end face of the fixing groove 802. The two sets of fixing screws 902 are respectively set on the first frame 1 and the second frame 2. The first frame 1, the second frame 2 and the fixing plate 9 are fixedly connected by the fixing screws 902, which facilitates installation and disassembly.

[0029] refer to Figure 4 To enhance aesthetics, a ramp 801 is provided at the connection between the thickened edge 8 and the first frame 1 and the second frame 2. The first frame 1 and the second frame 2 smoothly transition to the thickened edge 8 through the cooperation of the ramp 801.

[0030] refer to Figure 6To prevent displacement during assembly, abutment plates 10 are fixedly connected at the four corners inside the first frame 1 and the second frame 2. Connecting rods 11 and insertion rods 12 are fixedly connected to the inner end faces of the two sets of abutment plates 10. The insertion rods 12 are movably inserted into the interior of the connecting rods 11.

[0031] Working method: During operation, insert the plug rod 12 into the connecting rod 11 to prevent the first frame 1 and the second frame 2 from shifting during assembly. By setting the thickened edge 8, a fixing groove 802 can be opened inside it. By setting the ramp 801, the frame can gradually transition smoothly to the thickened edge 8. The thickened edge 8 has better strength and can prevent collision damage. Then, the fixing plate 9 is inserted, and the limiting block 901 is inserted into the limiting groove 803 to make the first frame 1 and the second frame 2 inseparable. Then, it is fixed with the fixing screw 902. This completes the assembly of the device frame. This device can install LCD screens inside the frames on both sides, which facilitates the assembly of the device and improves production efficiency. After assembly, the flat LCD panel 4 and the curved LCD panel 3 can be controlled separately by the control button 6. They can be turned on individually or simultaneously as needed, which facilitates the use of the device.
