In order for your reviewer to have a further understanding and understanding of the features of the present invention and the effects achieved, only examples and detailed descriptions are provided. The description is as follows: please refer to the second figure, which is the film of the present invention The structure diagram of the first embodiment of the solar cell display device. As shown in the figure, the display device 3 with thin film solar cells of the present invention includes: a substrate layer 30; a liquid crystal layer 32 disposed on the substrate layer 30; a filter layer 34 including a plurality of filters 340, each A filter 340 is arranged adjacent to each other and is arranged on the liquid crystal layer 32, and each filter 340 adjacently includes a containing chamber 342; a plurality of thin-film solar cells 36 are arranged in the containing chambers 342 And an optical substrate 38 disposed on the filter layer 34.

The above-mentioned substrate layer 30 is a layer body composed of Array Glass, which serves as a substrate. The above-mentioned liquid crystal layer 32 is a layer composed of a plurality of liquid crystals (Liquid Crystal) body. The above-mentioned filter layer 34 is a color filter composed of a plurality of filters 340 arranged adjacent to each other, and the filters 340 are a combination of red, green, and blue. For one of the groups, the following embodiments are described by the arrangement of red, green, and blue in order from right to left in the figure, but it is not limited to this. The above-mentioned thin-film solar cells 36 are amorphous silicon (Amorphus Silicon, a-Si), microcrystalline silicon (Nanocrystalline Silicon, nc-Si, Microcrystalline Silicon, mc-Si), compound semiconductor II-IV group [CdS, CdTe (tellurium) Cadmium), CuInSe2], Dye-Sensitized Solar Cell, Organic/polymer solar cells, CIGS (Copper Indium Selenide) and other battery structures. The above-mentioned optical substrate 38 is glass.

For example, light (not shown) may enter the filter layer 34 from the substrate layer 30, so that the filter 340 and the thin-film solar cell 36 of the filter layer 34 receive the light and perform their own related functions. When at least one light enters the filter layer 34 through the optical substrate 38, the non-essential light band can be filtered by the filter 340 of each color, and only the necessary light wave band can enter the next layer. In addition, after the thin film solar cell 36 receives light, it can perform photoelectric conversion to generate electrical energy, and the electrical energy can be effectively used in the subsequent. Among them, the thin film solar cell 36 also functions as the conventional black matrix 140 when the light enters the filter layer 34. The light shielding function of the position; a first distance D1 between the bottom of the containing chambers 342 and the top of the liquid crystal layer 32 is greater than a second distance between the top of the containing chambers 342 and the bottom of the optical substrate 38 The distance D2, that is, the positions of the accommodating chambers 342 are biased toward or close to the optical substrate 38.

Please refer to the first figure and the second figure again. As shown in the first figure, in the traditional display device 1 with a solar cell structure, the filter layer 14 needs to be provided with a plurality of black matrices 140 adjacent to the plurality of filters 142 included in the filter layer 14. The intention is The light that does not necessarily enter the filter layer 14 is effectively blocked. As shown in the second figure, the display device 3 with thin-film solar cells according to the first embodiment of the present invention simplifies the filter layer 34 and does not need to provide the black matrix 140 of the prior art, and each filter in the filter layer 34 An accommodating chamber 342 is arranged adjacent to the 340 so that the thin-film solar cells 36 are arranged in the accommodating chamber 342. In this way, the thin-film solar cell 36 itself does not have light-transmitting characteristics It is arranged at the adjacent position (the junction of the color layers) of each filter 340 to replace the conventional black matrix 140, and has the following advantages:

1. Streamline the settings of components and further save manufacturing costs.

2. Taking into account the original effect of the black matrix 140, it can block the light, and because it is arranged adjacent to the second filter 340, it can effectively reduce the light mixing caused by the adjacent filters 340 of different colors when receiving/outputting light. , And improve the accuracy of filtering out unwanted light bands.

3. Due to the use of thin-film solar cells 36, the thickness of the overall display device 3 is further reduced.

In addition, arranging the thin film solar cell 36 in the accommodating chamber 342 also plays the role of protecting the thin film solar cell 36, and there is no need to add a protective layer 18 to protect the solar cell 180 as shown in the first figure. At the same time, it also protects the thin film solar cell. 36 and reduce the overall structural thickness of the display device 3. Furthermore, the present invention does not need to add the solar cell substrate layer 20 shown in the first figure, but directly uses the optical substrate 38 disposed above the filter layer 34 as the filter layer 34 and the filter layer of the thin film solar cell 36 It can reduce the thickness of the display device 3.

That is, the way that each filter 340 is arranged adjacent to each other is close to each other, so that there is no gap between the adjacent places of each filter 340. This design method can reduce the leakage of light input to the filter layer 34 from the gap G, and avoid affecting the performance of the output screen of the display device 3.

Please refer to FIG. 4, which is a schematic structural view of the third embodiment of the display device with thin-film solar cells of the present invention. As shown in the figure, the difference between the third embodiment of the present invention and the first embodiment is that the optical substrate 38 is disposed on a surface S of the thin-film solar cells 36 and the optical filters 340 that are aligned with each other. If the space of the accommodating chamber 342 is not enough to completely accommodate the thin-film solar cell 36, a part of the thin-film solar cell 36 will protrude beyond the filter layer 34. In this way, in order to enable the optical substrate 38 to be placed on the filter layer 34 as expected, it is necessary to construct the optical substrate 38 into the shape of the element (thin film solar cell 36) protruding corresponding to the filter layer 34 to avoid affecting the filter layer. The degree of lamination and bonding of the optical layer 34 and the optical substrate 38. Therefore, as shown in the third and fourth pictures As shown, the height of the accommodating chamber 342 can be greater than or equal to the height of the filter 340; further, as shown in the fourth figure, the thin-film solar cell 36 is disposed behind the accommodating chamber 342, and the upper surface of the thin-film solar cell 36 362 can be aligned with the upper surface S of the filter 340. In addition, since the accommodating chamber 342 has been designed to completely accommodate the thin-film solar cell 36, the thickness of the filters 340 of the filter layer 34 can be exactly equal to the height of the accommodating chamber 342 to reduce the thickness of the overall display device 3. . Of course, the thickness of the filters 340 of the filter layer 34 can also be greater than the containing chamber 342, and it is not limited thereto.
