Step S6 is a cutting step, in which the periphery of the display panel is cut in step S6 to remove at least a part of the main body layer 1 located at the outer edge of the light guide portion 2. The cutting step will lead the cutting of the main part layer 1 of light portion 2 outer fringe to fall, when guaranteeing display panel structural strength, let display panel's outer fringe be for can see through light guide portion 2, can be applied to the use scene of polylith display panel concatenation for polylith display panel does not have the frame each other when the concatenation, has improved the visual effect after the concatenation of polylith display panel.
The periphery in the cutting step S6 means the periphery of the display panel, and the shape of the cut and the range of the cut need to be determined depending on the display effect to be actually achieved by the display panel, and is not exclusive.
Note that, although the light guide portion providing step S1 to the cutting step S6 are performed in this embodiment, the order of steps is not necessarily performed in the order of steps 1 to 6, and may be changed in other embodiments of the present invention. For example, the machining sequence of the cutting step S6 may be set between the groove portion setting step S3 and the surface layer setting step S4, which may reduce the cutting of the surface layer 7, and is advantageous for cost saving. This is merely an example and other step changes are possible and will not be described further here.
The light guide portion providing step S1 includes a plurality of sub-steps, fig. 6 is a flowchart of a light guide portion providing step S1 according to a third embodiment of the present invention, and the light guide portion providing step S1 is described in detail below.
As shown in fig. 6, first, the process proceeds to a hole forming step S11, where a hole forming portion 11 is formed in the main body layer 1. In the present embodiment, the opening portion 11 is milled in the main body layer 1 using a milling machine, and the opening portion 11 has a certain depth but does not penetrate through the main body layer 1. After the machining of the hole 11 is completed, the process proceeds to injection step S12.
In the injection step S12, the molten liquid organic glass is injected into the opening portion 11, so that the organic glass is injection-molded in the opening portion 11, thereby forming the light guide portion 2 matching with the opening portion 11. The light guide part 2 is arranged in the injection molding processing mode, the light guide part 2 is matched with the opening part 11 more tightly, the gap between the light guide part 2 and the opening part 11 is reduced and even eliminated, the problems of light refraction and reflection caused by the gap are reduced and even avoided as much as possible, light entering the light guide part 2 is more uniform, and the light guide effect of the light guide part 2 is effectively improved. In addition, the light guide part 2 is tightly matched with the opening part 11, so that the light guide part 2 and the main body layer 1 are more stably connected, the light guide part 2 is prevented from falling off from the main body layer 1, and the service life of the light guide part 2 and even the service life of the display panel are prolonged. After the injection molding of the light guide portion 2 is completed, the process proceeds to a smoothing step S13. In other embodiments of the present invention, the light guide part 2 may be disposed on the opening part 11 by means of insert bonding, and the shape and size of the light guide part 2 may be matched with those of the opening part 11.
In the smoothing step S13, the main body layer 1 in which the light guide portion 2 is embedded is milled flat and then ground flat. The main body layer 1 embedded with the light guide part 2 is milled and then ground, so that the side surface embedded with the light guide part 2 is smooth, and the light is uniform when being emitted out through the light guide part 2, thereby being beneficial to ensuring the light guide effect of the light guide part 2. In addition, because the side of the main body layer 1 embedded with the light guide part 2 needs to be attached to the pattern layer 6, the close attachment degree of the main body layer 1 and the pattern layer 6 is also improved.
Those of skill in the art will appreciate that the specific features of the various embodiments may be adaptively separated or combined. Such splitting or combining of specific features does not cause the technical solutions to deviate from the principle of the present invention, and therefore, the technical solutions after splitting or combining will fall within the protection scope of the present invention. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
