Description

TECHNICAL FIELD

[0001] The present disclosure relates to a liquid crystal display and a double-layer liquid crystal display, in particular, to a liquid crystal display and a double-layer liquid crystal display combined with a solar module. BACKGROUND

[0002] A bistable liquid crystal display only consumes power when updating a picture, and no power is needed when maintaining a static display picture. With the climate change becoming more and more serious, combining a bistable liquid crystal display with a solar cell can absorb ambient light and convert it into power to drive the liquid crystal display to update a picture, thereby saving energy.

[0003] However, if the display is set outdoors and shaded by environmental dirt, leaves or other obstacles, the current of the solar cell in the shaded area is low, which reduces the power generation efficiency of other solar cells connected in series with the solar cell in the shaded area, and the cell in the shaded area presents a high resistance state, which is prone to local heating.

[0004] Furthermore, when the liquid crystal display displays a high-contrast picture, the color displayed by different areas of the display is different, and the light intensity of each solar cell is different, which also causes the power generation efficiency of the solar cells in different areas to be uneven.

[0005] Therefore, there is a lack of a liquid crystal display or a double-layer liquid crystal display that can adjust the overall power generation efficiency in the market, and relevant industries are seeking solutions. CONTENT OF THE INVENTION

Also, the combination of elements / units / circuits in this document is not a combination that is generally known, conventional or well-known in the art, and whether the combination of elements / units / circuits is easy to be completed by those skilled in the art cannot be determined by whether the elements / units / circuits themselves are well-known.

[0045] Referring to Figure 1 and Figure 2 , Figure 1 is a top view schematic diagram illustrating a liquid crystal display of a first embodiment of the present disclosure; and Figure 2 is a top view schematic diagram illustrating a liquid crystal display of a second embodiment of the present disclosure; and Figure 1FIG. 1 is a side view schematic diagram of a liquid crystal display according to an embodiment of the present disclosure. The liquid crystal display 100 comprises a display panel 110 and a solar module 120. The solar module 120 is disposed on a surface of the display panel 110 and comprises a polymer layer 121, a plurality of solar cells 122, at least one diode 123, and a light-transmitting layer 124. The solar cells 122 are electrically connected to each other and are embedded in the polymer layer 121 at intervals. The at least one diode 123 is embedded in the polymer layer 121 and is connected in parallel to at least one of the solar cells 122. The light-transmitting layer 124 is disposed between the display panel 110 and the polymer layer 121. Any two adjacent ones of the display panel 110, the light-transmitting layer 124, and the polymer layer 121 are bonded by an optical adhesive. In this way, the liquid crystal display 100 of the present disclosure arranges the diode 123 in the solar module 120, thereby adjusting the power generation efficiency without increasing the overall thickness of the liquid crystal display 100.

[0046] In detail, the display panel 110 can be a cholesteric liquid crystal panel, the polymer layer 121 can be ethylene vinyl acetate (EVA), polyolefin elastomer (POE), Tedlar, or other elastic polymers, any one of the solar cells 122 can be one of a silicon wafer solar cell, a thin-film solar power module, an organic solar power module, a perovskite solar power module, and a dye-sensitized solar power module, the diode 123 can be a bypass diode, and the light-transmitting layer 124 can be tempered glass, but the present disclosure is not limited thereto.

[0047] In the first embodiment, the number of the at least one diode 123 is a plurality, the diodes 123 correspond to the solar cells 122 respectively, and the diodes 123 are connected in parallel to each other. A thickness TH1 of the diode 123 can be less than or equal to 1.2 mm, but the present disclosure is not limited thereto. The solar cells 122 are connected to each other by a wire W1, and the power stored by all the solar cells 122 is integrated to a signal output end 111 through the wire W1 to supply power to the display panel 110.

[0048] Further, the solar module 120 can further comprise a plurality of light-shielding layers 125. The light-shielding layers 125 are embedded in the polymer layer 121 and correspond to the diodes 123 respectively. The light-shielding layers 125 are disposed between the diodes 123 and the light-transmitting layer 124. By disposing the light-shielding layers 125 at positions corresponding to the diodes 123, the display effect of the display panel 110 can be prevented from being affected by the reflection of the diodes 123 made of metal materials.

[0049] In addition, the LCD 100 may further include a backplane 130. The backplane 130 is disposed on one side of the solar module 120. The solar module 120 is located between the backplane 130 and the display panel 110. The backplane 130 may be made of black or opaque material to increase the contrast of the LCD 100.

[0050] Please refer to Figures 1 to 3 , Figure 3 It is drawn according to Figure 1 When the LCD 100 is set in an outdoor environment, the LCD 100 may be blocked by outdoor obstacles, such as Figure 3 As shown, area A1 of the LCD 100 is shaded by an obstruction, which reduces the current flowing through the solar cells 122 in area A1. Consequently, the current does not flow through the solar cells 122, but only through the diodes 123 corresponding to the shaded area. Thus, the LCD 100 of the present disclosure, by providing the diodes 123 in the solar modules 120, can mitigate the problem of reduced power generation efficiency of the solar cells 122 due to partial shading.

Two adjacent solar cells 122a are connected in series, each corresponding to one diode 123. When at least one of the two solar cells 122a connected in series is shaded or experiences low current, current flows through the corresponding diode 123 instead. In other embodiments, the solar cell may be adjusted to other sizes, but the present disclosure is not limited thereto.
