It should be noted that the frame of the liquid crystal display 100 described in the following embodiments of the present invention mainly refers to the middle frame 108 of the liquid crystal display 100.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a frame of a liquid crystal display according to a first embodiment of the invention. As shown in fig. 2, the frame 200 of the liquid crystal display 100 of the embodiment includes a first frame main body 201 and a second frame main body 202 connected to each other, and a gap 203 is formed at a connection position of the first frame main body 201 and the second frame main body 202, the gap 203 is disposed in a curve shape near a first edge 204 of the first frame main body 201 and a second edge 205 of the second frame main body 202, respectively, wherein the first frame main body 201 and the second frame main body 202 are bent at a first angle α, and the first edge 204 and the second edge 205 are engaged with each other.
The matching between the first edge 204 and the second edge 205 may specifically include the following three cases:
in the first case, when the first edge 204 and the second edge 205 are engaged with each other, the first edge 204 and the second edge 205 may be completely attached, i.e., there is no gap between the first edge 204 and the second edge 205.
In the second case, when the first edge 204 and the second edge 205 are fitted to each other, the first edge 204 and the second edge 205 partially fit each other, and a gap is partially formed.
In the third case, when the first edge 204 and the second edge 205 are fitted to each other, the first edge 204 and the second edge 205 are fitted to each other and spaced apart from each other, and the gap between the first edge 204 and the second edge 205 is also curved.
In this embodiment, a third case is taken as an example, and the structure of the frame of the liquid crystal display shown in fig. 2 is that when the first frame main body 201 and the second frame main body 202 are bent at the first angle α, the first edge 204 and the second edge 205 are fitted to each other and spaced apart from each other, and the gap between the first edge 204 and the second edge 205 is curved.
The present invention is not limited to which structure the first edge 204 and the second edge 205 are engaged with each other, as long as the bent position of the frame 200 cannot transmit light when the first edge 204 and the second edge 205 are engaged with each other.
Therefore, in the present embodiment, a notch 203 is formed at a connection position of the first frame main body 201 and the second frame main body 202, and the notch 203 is disposed close to the first edge 204 of the first frame main body 201 and the second edge 205 of the second frame main body 202 in a curved manner, respectively, so that when the first frame main body 201 and the second frame main body of the frame of the liquid crystal display 100 of the present embodiment are bent at the first angle α, the first edge 204 and the second edge 205 can be engaged with each other, thereby preventing light from leaking from the notch 203 at the bent position, and improving product performance.
The invention further provides a frame 200 of the liquid crystal display 100 of the second embodiment, which is described on the basis of the frame 200 of the liquid crystal display 100 disclosed in the first embodiment. In the present embodiment, the gap 203 between the connection portions of the first frame body 201 and the second frame body 202 may be formed by CNC (Computer numerical control) milling. Of course, in other embodiments, the gap 203 between the connection portions of the first frame main body 201 and the second frame main body 202 may be formed by other methods, which are not limited herein.
As shown in fig. 3, the first edge 204 may be provided with a first convex portion 2041, the second edge 205 may be provided with a first concave portion 2051, and when the first frame body 201 and the second frame body 202 are bent at a first angle α, the first convex portion 2041 is inserted into the first concave portion 2051, so as to prevent light from leaking from the notch 203 and causing light leakage, thereby improving product performance.
Optionally, the first edge 204 may be further provided with a second recess 2042, and the second edge 205 may be provided with a second protrusion 2052, wherein the second protrusion 2052 is inserted into the second recess 2042 when the first frame body 201 and the second frame body 202 are bent at the first angle α to each other. In the embodiment shown in fig. 3, the first edge 204 is provided with a first protrusion 2041 and a second recess 2042, the second edge 205 is provided with a first recess 2051 and a second protrusion 2052, and when the first frame body 201 and the second frame body 202 are bent at a first angle α, the first protrusion 2041 of the first edge 204 is inserted into the first recess 2051 of the second edge 205, and the second protrusion 2052 of the second edge 205 is inserted into the second recess 2042 of the first edge 204, so that even if there is a notch 203 during bending of the frame of the liquid crystal display 100, light cannot be transmitted from the notch 203, thereby improving product performance.
Wherein, the workpiece has resilience (which means the ability of the object to quickly return to the original shape after the external force causing the deformation of the object is removed). Therefore, in an embodiment, when the first frame body 201 and the second frame body 202 of the frame of the liquid crystal display 100 are required to be bent at the first angle α, the first frame body 201 and the second frame body 202 are required to be bent at the second angle β in advance, as shown in fig. 4. The first edge 204 and the second edge 205 are configured to allow the first frame body 201 and the second frame body 202 to be capable of bending over each other to a second angle β, wherein the second angle β is smaller than the first angle α, so that after the external force of bending is removed, the workpiece utilizes the resilience of the workpiece, and the first frame body 201 and the second frame body 202 are resilient to bend to form a first angle α.
The present invention further provides a frame 300 of a liquid crystal display 100 according to a third embodiment, which is different from the frame 200 of the liquid crystal display 100 disclosed in the first embodiment in that, as shown in fig. 5, a first edge 304 of a first frame main body 301 of the frame 300 of the liquid crystal display 100 according to the present embodiment may be configured as a plurality of straight bends, and a second edge 305 of a second frame main body 302 may also be configured as a plurality of straight bends, so that the processing operation of the notch 303 of the frame 300 of the liquid crystal display 100 according to the present embodiment is simpler compared to the frame 200 of the liquid crystal display 100 according to the first embodiment.
The present invention further provides a frame 400 of a liquid crystal display 100 of a fourth embodiment, which is different from the frame 200 of the liquid crystal display 100 disclosed in the first embodiment in that, as shown in fig. 6, the depth of the notch 403 of the frame 400 of the present embodiment is greater than the depth of the notch 203 of the frame 200 of the first embodiment, and therefore, the present embodiment can also achieve the effect of shielding light by adjusting the depth of the notch 203 of the frame of the liquid crystal display 100. In other words, the depth of the notch 203 of the frame of the lcd 100 in the present invention can be adjusted according to the actual situation, so long as the structure of the notch 203 can achieve the effect of shielding light, and the present invention is not limited thereto.

Of course, in other embodiments, when the first edge 204 is provided with only the first convex portion 2041 and the second edge 205 is provided with the first concave portion 2051, the first convex portion 2041 is inserted into the first concave portion 2051 when the first frame body 201 and the second frame body 202 are disposed at the first angular bend α to each other.
