[0025] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] The utility model provides a photovoltaic charging liquid crystal display screen, which includes a backlight module, a TFT module and a first cover plate, wherein the TFT module is arranged above the backlight module, the first cover plate is arranged above the TFT module, a main board is arranged below the backlight module, a photovoltaic film module is arranged on the lower surface of the first cover plate, an FPC is bound to the lower surface of the first cover plate, the FPC is electrically connected to the photovoltaic film module, and the main board is electrically connected to the FPC.

[0027] Since a photovoltaic thin film module is provided on the lower surface of the first cover plate, the FPC is electrically connected to the photovoltaic thin film module, and the main board is electrically connected to the FPC, so that after the photovoltaic thin film module generates electricity, the electricity can be transmitted to the battery through the FPC and the main board, so that the user can continuously charge the battery while working under the sun, thereby improving the battery life and thus improving the competitiveness of the product.

[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0029] Example 1

[0030] See also Figure 1 , a photovoltaic charging liquid crystal display screen provided by the utility model, which includes a backlight module 100, a TFT module 200 and a first cover plate 1, the TFT module 200 is arranged above the backlight module 100, the first cover plate 1 is arranged above the TFT module 200, a main board 2 is arranged below the backlight module 100, a photovoltaic film module 3 is arranged on the lower surface of the first cover plate 1, an FPC4 is bound to the lower surface of the first cover plate 1, the FPC4 is electrically connected to the photovoltaic film module 3, and the main board 2 is electrically connected to the FPC4. Since the photovoltaic film module 3 is arranged on the lower surface of the first cover plate 1, the FPC4 is electrically connected to the photovoltaic film module 3, and the main board 2 is electrically connected to the FPC4, the photovoltaic film module 3 can transmit the electricity to the battery through the FPC4 and the main board 2 after generating electricity, so that the user can continuously charge the battery when working under the sun, improve the endurance, and thus improve the competitiveness of the product.

[0031] Furthermore, the photovoltaic thin film module 3 is located in the non-visible area to avoid affecting the normal display of the TFT module 200 .

[0032] Furthermore, the thickness of the photovoltaic thin film module 3 is 0.5 mm to 1 mm.

[0033] Example 2

[0034] See also Figure 2As a further optimization scheme of Example 1, in this embodiment, a second cover plate 5 is provided below the first cover plate 1, an ink layer 6 is provided on the lower surface of the photovoltaic film module 3, and the second cover plate 5 and the first cover plate 1 are fixed by an adhesive layer 7, and the adhesive layer 7 completely covers the ink layer 6 and the lower surface of the first cover plate 1. Since there is another first cover plate 1 above the second cover plate 5, and the adhesive layer 7 is printed on the entire back of the first cover plate 1, it covers the ink layer 6 in the non-visible area and the lower surface of the first cover plate 1 in the visible area, fills the ink step difference, and does not cause the phenomenon of laminating bubbles and edge yellow spots. The second cover plate 5 can be fully laminated with the upper polarizer through liquid optical glue. Since the second cover plate 5 is not provided with an ink layer 6, it will not cause the phenomenon of laminating bubbles and edge yellow spots, thereby avoiding display abnormalities of the liquid crystal display module, thereby reducing the probability of defective products in the liquid crystal display module, and the production and manufacturing costs of the liquid crystal display module will also be greatly reduced.

[0035] And when the first cover plate 1 is impacted by external force, the first cover plate 1 will break first. Due to the buffering effect of the adhesive layer 7, the second cover plate 5 is not easy to break, so the second cover plate 5 and the main screen can be well protected. When the first cover plate 1 is broken, the first cover plate 1 can be easily peeled off, and only a new first cover plate 1 needs to be replaced. There is no need to replace the entire LCD display module, thereby greatly reducing the maintenance cost of the LCD display module, thereby improving the product competitiveness of the LCD display module, thereby meeting the company's growing quality requirements.

[0036] Furthermore, the thickness of the ink layer 6 is 8 μm to 15 μm.

[0037] Furthermore, the thickness of the adhesive layer 7 is 50 μm.

[0038] Furthermore, the upper surface of the first cover plate 1 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the first cover plate 1 and enhance the aesthetics.

[0039] Furthermore, the hardness of the first cover plate 1 is greater than the hardness of the second cover plate 5 to enhance the protection effect.

[0040] Furthermore, the thickness of the first cover plate 1 is 5 mm to 10 mm, and the thickness of the second cover plate 5 is 3 mm to 5 mm.
