The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0017] ​​Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0018] Specific embodiments of the present application are described herein with reference to the accompanying drawings.

[0019] Embodiment 1 In this embodiment, a self-charging extended-range liquid crystal television module is proposed, please refer to Figures 1-5 , the self-charging extended-range liquid crystal television module comprises a back plate 1 formed by one-piece stamping, a liquid crystal panel 2 arranged on the front side of the back plate 1, a plurality of LED light strips 3 and a light energy battery panel 4. Specifically, the back plate 1 is made of metal material, and the main part thereof forms a central recessed accommodating space through stamping process. The top side (upper edge) and the left and right side edges of the back plate 1 are integrally formed with a bending part 5 extending towards the inside of the accommodating space through bending process. In this embodiment, the bending part 5 is a sheet structure, and the included angle formed between the bending part 5 and the plane of the frame of the back plate 1 is 90°, which is beneficial to the accurate positioning and installation of each component. In other embodiments, the angle can be adjusted between 88° and 92° to adapt to different design tolerance requirements.

[0020] Please refer to Figure 3 , the bending part 5 ingeniously separates the frame area of the back plate 1 into two functional layers in the height direction, specifically, the upper layer as a first support layer and the lower layer as a second support layer. The first support layer is used to fix the liquid crystal panel 2, specifically, a high-adhesion double-sided tape 6 is pasted on the surface of the bending part 5 facing outward (i.e. facing the liquid crystal panel 2), and during assembly, the frame area of the liquid crystal panel 2 is accurately positioned and pressed on the double-sided tape 6, thereby realizing the firm fixation of the liquid crystal panel 2 and the back plate 1. This fixing method is simple to operate, reliable in connection, and is beneficial to realizing narrow frame design. The second support layer is used to accommodate and support the diffuser plate 8 and the diaphragm, the edge part of the diffuser plate 8 is placed into the space of the second support layer formed by the bending part 5, the side wall and the bottom of the back plate 1, in order to further improve the stability of the structure, a shock-absorbing strip 7 is installed in the space, which is pasted on the surface of the bending part 5 facing inward (i.e. facing the accommodating space), used to tightly fit the edge of the diffuser plate 8, plays a role of buffering and shock-absorbing, and prevents damage to the diffuser plate 8 and other optical diaphragms caused by vibration during transportation or use.

[0021] Please refer to Figure 3 and Figure 4In the light cavity formed by the accommodating space of the back plate 1 and the diffusion plate 8, a plurality of LED lamp strips 3 are arranged in an array, which are directly fixed on the bottom surface of the back plate 1, and a light energy panel 4 is arranged between two adjacent LED lamp strips 3, and in order to maximize the utilization of light energy, the inner surface of the whole light cavity (including the bottom surface and the side wall of the back plate 1) is coated with a layer of high-reflectivity reflective paper 9 except the position of the diffusion plate 8.

[0022] The working principle of the present application is as follows: when the liquid crystal television module works, the LED lamp strip 3 is powered to emit light, part of the light directly passes through the diffusion plate 8 to provide backlight for the liquid crystal panel 2, and the other part of the light is scattered in all directions, and the scattered light is reflected by the reflective paper 9 coated on the inner wall of the light cavity. After one or more reflections, most of the light will eventually pass through the diffusion plate 8, and part of the light will be directed and irradiated onto the light energy panel 4 arranged between the LED lamp strips 3, the light energy panel 4 absorbs the light energy and converts it into electrical energy, which is transmitted to the power management module of the module through the wire, used to supplement the power consumption of the module, or used to power other low-power modules. In this way, the light energy that would be lost due to multiple reflections and absorption is effectively recovered, thereby achieving the purpose of energy saving and consumption reduction.

[0023] The technical features of the above-described embodiments can be combined in any manner, and in order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present application.

[0024] The above-described embodiments only express several embodiments of the present application, which are described in detail and in detail, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
