Description

Technical Field

[0001] The utility model relates to the technical field of a cholesteric liquid crystal electronic reading device, in particular to a cholesteric liquid crystal electronic reading device and a cholesteric liquid crystal reader which utilize a high-efficiency thin-film photovoltaic cell and a supercapacitor power storage unit. Background Art

[0002] Existing electronic products all use a large number of disposable batteries or secondary batteries as energy storage materials, such as disposable batteries such as manganese dry batteries, alkaline batteries, silver oxide batteries, mercury batteries, and lithium batteries; secondary batteries such as nickel-cadmium batteries, lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries, lithium polymer batteries, and fuel cells. Among them, lithium-ion batteries are the largest energy storage materials. Although the energy storage density is high, lithium-ion batteries often have safety problems such as spontaneous combustion and explosion. Therefore, during transportation, such as air transportation, the transportation cost will increase, and the transportation protection procedures required during the transportation will become very complicated.

[0003] However, it is well known that among display devices, cholesteric liquid crystal display is an extremely power-saving display device, because cholesteric liquid crystal display is a display device that does not need to consume any electricity under static screen and only needs electricity when switching screens. In other words, when maintaining the same display screen, cholesteric liquid crystal display does not require electricity. In other words, cholesteric liquid crystal display is a very energy-saving and power-saving product with environmental protection concept.

[0004] In the prior art, patent publication number TW201346775A discloses a display type electronic tag and its setting management method, and is particularly directed to a display type electronic tag and its setting management method applied to wireless technology. In this invention, the traditional display type electronic tag, that is, the electronic tag that requires a built-in battery can be replaced, thereby avoiding the problem of having to replace the battery of the display type electronic tag with a new one when the battery is exhausted.

[0005] In the prior art, patent publication number TW202334865A discloses an electronic paper identification card system and an electronic paper identification card, which displays first image information and second image information through the electronic paper identification card to avoid the problem that most existing visitor identification cards are used once. If used once, it will cause a waste of resources. In the past, no personal information was displayed on the visitor identification card, and the user's identity may be stolen.

[0006] However, the power sources in the above two cases are too small. If the device needs to be used continuously today, there may be problems such as insufficient power when switching screens.

[0007] Therefore, the main purpose of the present invention is to provide a cholesteric liquid crystal electronic reading device, which solves the above problems by using a high-efficiency thin-film photovoltaic cell and a supercapacitor design on a cholesteric liquid crystal display with good energy saving effect. Utility Model Content

[0008] The purpose of the utility model is to provide a cholesterol liquid crystal electronic reading device, which utilizes the energy-saving characteristics of cholesterol liquid crystal displays and uses high-efficiency thin-film photovoltaic cells with supercapacitor power storage units to complete a cholesterol liquid crystal electronic reading device that does not require ordinary energy storage batteries and can have clean, safe energy storage and is lightweight.

[0009] The first preferred embodiment of the utility model is a cholesteric liquid crystal electronic reading device, which includes a cholesteric liquid crystal reader, a thin film photovoltaic cell, and a housing. The cholesteric liquid crystal reader has a display screen, which can be used to display the required images.

[0010] The shell has an upper cover, a lower cover, and a movable bending part connecting the upper cover and the lower cover. The thin-film photovoltaic cell is arranged on the inner surface of the upper cover, and the cholesterol liquid crystal reader is arranged on the inner surface of the lower cover. Through the movable bending part, the light-receiving surface of the photovoltaic cell can be covered on the display screen of the cholesterol liquid crystal reader.

[0011] The cholesteric liquid crystal reader also has a supercapacitor unit, a cholesteric liquid crystal display unit electrically connected to the supercapacitor unit, a display driving unit, a computing core unit, an input / output unit, a data storage unit and a second power transmission structure. The second power transmission structure is detachably electrically connected to the first power transmission structure, and is used to receive power from the thin-film photovoltaic cell and transmit it to the supercapacitor unit.

[0012] The input / output unit is used to connect to an external power device to transmit external power to the supercapacitor unit. That is to say, the first power transmission structure, the second power transmission structure, and the input / output unit are all used to transmit power to the cholesterol liquid crystal electronic reading device.

[0013] The utility model then proposes a second preferred embodiment, which is another cholesterol liquid crystal electronic reading device, comprising a cholesterol liquid crystal reader, a thin film photovoltaic cell, and a housing. The cholesterol liquid crystal reader has a display screen, and the thin film photovoltaic cell has a light receiving surface and a first power transmission structure. The housing has a first window and a second window adjacent to the first window, the cholesterol liquid crystal reader is arranged in the first window, the thin film photovoltaic cell is arranged in the second window, and the cholesterol liquid crystal reader is arranged in the first window, and the display screen and the light receiving surface are both facing outward.

[0014] The cholesterol liquid crystal reader also has a supercapacitor unit, a cholesterol liquid crystal display unit electrically connected to the supercapacitor unit, a display driving unit, a computing core unit, an input / output unit, a data storage unit and a second power transmission structure. The second power transmission structure is electrically connected to the first power transmission structure, and is used to receive power from the thin-film photovoltaic cell and transmit it to the supercapacitor unit. The input / output unit is used to connect to an external power device and transmit external power to the supercapacitor unit.

[0015] Therefore, the cholesteric liquid crystal electronic reading device provided by the utility model utilizes the supercapacitor device to store electricity for use by the cholesteric liquid crystal electronic reading device. When the supercapacitor device is insufficient in power, the thin film photovoltaic cell can generate sufficient power indoors, and then the input / output unit, the first power transmission structure, and the second power transmission structure are used to transmit power to the supercapacitor device. When the use environment is not sufficient for the thin film photovoltaic cell to generate power, the input / output unit is connected to an external power device to transmit external power to the supercapacitor unit, which can also be used by the cholesteric liquid crystal electronic reading device.

Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; the technical features designed in different implementation modes of the utility model described below can be combined with each other as long as they do not conflict with each other; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The purpose of the utility model is to provide a cholesterol liquid crystal electronic reading device, which utilizes the energy-saving characteristics of the cholesterol liquid crystal display and uses a highly efficient and thin film photovoltaic cell with a supercapacitor power storage unit to complete a cholesterol liquid crystal electronic reading device that does not require a general energy storage battery and only requires power when switching screens.

[0050] See also Figure 1 , Figure 1This is the first preferred embodiment of the present invention, a schematic diagram of an open cholesterol liquid crystal electronic reading device. In other words, this is a schematic diagram of a cholesterol liquid crystal electronic reading device 1 when it is in the shape of a book. However, the present invention is not limited to this schematic diagram. The present invention is a cholesterol liquid crystal electronic reading device 1, such as Figures 1 to 3 As shown, it includes a cholesteric liquid crystal reader 10 , a thin film photovoltaic cell 20 , and a shell 30 .

[0051] The cholesterol liquid crystal reader 10 has a display screen 101, that is, a display screen, which can be used to display the desired picture. The display screen only needs to provide power when switching pictures. If it remains in the same picture, no additional power is required.

[0052] The thin film photovoltaic cell 20 has a light receiving surface 21. The thin film photovoltaic cell 20 is a type of solar cell and has the characteristics of being light and thin. In a preferred embodiment, a cell that can be used indoors is selected, and the photoelectric conversion efficiency is preferably greater than 20%.

[0053] As shown in the figure, the shell 30 can be disassembled into an upper cover 31, a lower cover 32, and a movable bending portion 33 connecting the upper cover 31 and the lower cover 32. The thin-film photovoltaic cell 20 can be set on the inner surface of the upper cover 31, and the cholesterol liquid crystal reader 10 will be set on the inner surface of the lower cover 32. The upper cover 31 and the lower cover 32 are closed by the movable bending portion 33, that is, the cholesterol liquid crystal electronic reading device 1 is closed, so that the light-receiving surface 21 of the thin-film photovoltaic cell 20 can cover the display screen 101 of the cholesterol liquid crystal reader 10, so that the cholesterol liquid crystal electronic reading device can be easy to carry.

[0054] Continue, see Figure 2 And with Figure 1 , Figure 2 The first preferred embodiment of the present invention is a schematic diagram of the structure of a cholesteric liquid crystal electronic reading device. In the first embodiment, the cholesteric liquid crystal electronic reading device 1 includes a cholesteric liquid crystal reader 10 , a thin film photovoltaic cell 20 , and a housing 30 .

[0055] The thin-film photovoltaic cell includes not only a light-receiving surface 21 , but also a first power transmission structure 22 .

[0056] The cholesteric liquid crystal reader 10 further comprises a supercapacitor unit 11, a cholesteric liquid crystal display unit 12 electrically connected to the supercapacitor unit 11, a display driving unit 13, a computing core unit 14, an input / output unit 15, a data storage unit 16 and a second power transmission structure 17.

[0057] Among them, the second power transmission structure 17 is detachably electrically connected to the first power transmission structure 22, and is used to receive power from the thin-film photovoltaic cell 20 to transmit it to the supercapacitor unit 11. That is to say, the electrical energy converted by light energy through the thin-film photovoltaic cell 20 can be transmitted to the supercapacitor unit 11 via the first power transmission structure 22 and the detachable second power transmission structure 17, and the supercapacitor unit 11 can then provide power to the computing core unit 14, and the computing core unit 14 then provides power to the data storage unit 16 and the display driving unit 13 respectively.

[0058] Because the input / output unit 15 can be used to connect to an external power device, external power can also be transmitted to the supercapacitor unit 11. That is to say, the first power transmission structure 22, the second power transmission structure 17, and the input / output unit 15 are all used to transmit power to the supercapacitor unit 11, and the supercapacitor unit 11 then provides power to the units in the cholesterol liquid crystal reader 10 for use.

[0059] In the cholesterol liquid crystal electronic reading device 1 , the input / output unit 15 can also be used to connect to an external data device to receive external data and transmit it to the computing core unit 14 . The computing core unit 14 can then store the external data in the data storage unit 16 .

[0060] In the cholesterol liquid crystal electronic reading device 1, the thin film photovoltaic cell 20 can be a dye-sensitized solar cell (DSSC), also known as a dye-sensitized cell. The dye-sensitized cell is not specifically used outdoors under direct sunlight, but is mainly used in indoor low-light and semi-outdoor environments. Under indoor low-light conditions, the photoelectric conversion efficiency of the dye-sensitized cell is still very high, and experiments have shown that it can be as high as 30%.

[0061] The main reason why we did not choose traditional silicon solar cells is that they are heavy and are mostly used outdoors under direct sunlight, where they have better photoelectric conversion efficiency. At the same time, silicon solar cells not only consume energy in the process, but also cause a lot of pollution and waste, so they are costly and less environmentally friendly.

[0062] In this embodiment, the thin film photovoltaic cell 20 can also be an amorphous silicon photovoltaic cell, a microcrystalline silicon photovoltaic cell, a compound semiconductor II-IV photovoltaic cell, an organic conductive polymer photovoltaic cell, a perovskite photovoltaic cell, or a copper indium selenide photovoltaic cell. The characteristics of this group are that the light absorption capacity for the visible spectrum is about 500 times stronger than that of a crystalline silicon photovoltaic cell, and the amorphous silicon photovoltaic cell is placed at a depth of 1.5 meters, and the conversion efficiency does not drop much. Therefore, when the cholesterol liquid crystal electronic reading device 1 is used underwater, it can also effectively provide power through the amorphous silicon photovoltaic cell.

[0063] See also Figure 3 , is a schematic diagram of another arrangement of the supercapacitor unit 11 in the first preferred embodiment of the utility model. Slightly different from the above, in this embodiment, the cholesterol liquid crystal reader 10 is also provided with an opening and a detachable cover covering the opening. From the opening to the inside of the cholesterol liquid crystal reader 10, a receiving area and a third power transmission structure 183 are formed. The supercapacitor unit 11 is arranged in the receiving area and is electrically connected to the third power transmission structure 183, thereby connecting to the input / output unit 15 to transfer power to other components. This arrangement is to set the supercapacitor unit 11 in a detachable and replaceable form. When the original supercapacitor unit 11 fails or runs out of power, it is convenient to replace it with other new, fully powered supercapacitor units 11; or the original exhausted supercapacitor unit 11 can be easily removed and charged in other external devices and then installed back.

[0064] See also Figure 4 And with Figure 5 , is the second preferred embodiment of the utility model, a cholesterol liquid crystal electronic reading device 2, Figure 4 is a schematic diagram of the appearance of the second preferred embodiment, Figure 5 2 is a schematic diagram of the structure of the second preferred embodiment. The cholesteric liquid crystal electronic reading device 2 comprises a cholesteric liquid crystal reader 10 , a thin film photovoltaic cell 20 , and a housing 90 .

[0065] like Figure 4 As shown, the housing 90 has a first window 91 and a second window 92 adjacent to the first window 91. The cholesterol liquid crystal reader 10 is arranged at the position of the first window 91, and the thin film photovoltaic cell 20 is arranged at the position of the second window 92. The cholesterol liquid crystal reader 10 has a display screen 101 for displaying images, and the thin film photovoltaic cell 20 has a light receiving surface 21 for receiving light, and the display screen 101 and the light receiving surface 21 are both facing outward. When the light receiving surface 21 receives light, the thin film photovoltaic cell 20 can convert energy to provide electrical energy to the display screen 101 of the cholesterol liquid crystal reader 10 to display images. Among them, the thin film photovoltaic cell 20 is preferably a dye-sensitized photovoltaic cell, and can also be an amorphous silicon photovoltaic cell, a microcrystalline silicon photovoltaic cell, a compound semiconductor II-IV photovoltaic cell, an organic conductive polymer photovoltaic cell, a perovskite photovoltaic cell, or a copper indium selenide photovoltaic cell.

[0066] Please refer to Figure 5The thin-film photovoltaic cell 20 located at the second window 92 has a first power transmission structure 22, and the cholesterol liquid crystal reader 10 located at the first window 91 further includes a supercapacitor unit 11, a cholesterol liquid crystal display unit 12, a display driving unit 13, a computing core unit 14, an input / output unit 15, a data storage unit 16, a second power transmission structure 17, and a third power transmission structure 183.

[0067] The second power transmission structure 17 can be detachably electrically connected to the first power transmission structure 22, so that the power of the thin-film photovoltaic cell 20 can be received and transmitted to the ultracapacitor unit 11. Since the input / output unit 15 is connected to an external power device, the external power can be transmitted to the ultracapacitor unit 11 via the second power transmission structure 17. The input / output unit 15 is also used to connect to an external data device to receive external data and transmit it to the computing core unit 14. The received external data can be stored in the data storage unit 16.

[0068] In addition to being fixedly arranged in the housing 90, the supercapacitor unit 11 can also be arranged in a detachable and replaceable form. When the original supercapacitor unit 11 fails or runs out of power, it is convenient to replace it with a new supercapacitor unit 11 that is fully charged; or the supercapacitor unit 11 that has run out of power can be easily removed and charged in other external devices and then installed back. In order to achieve this purpose, the housing 90 is also provided with an opening and a detachable cover covering the opening. The opening has a receiving area and a third power transmission structure 183 inside the cholesterol liquid crystal reader 10. At the same time, the supercapacitor unit 11 is also arranged in the receiving area and is electrically connected to the third power transmission structure 183, so that the cholesterol liquid crystal display unit 12, the display drive unit 13, the computing core unit 14, the input and output unit 15, the data storage unit 16, and the second power transmission structure 17 can be electrically connected to the supercapacitor unit 11 through the third power transmission structure 183.

[0069] In summary, the cholesterol liquid crystal electronic reading device provided by the utility model uses the super capacitor device to store electricity for use in the cholesterol liquid crystal electronic reading device in the manner described in the first embodiment and the second embodiment, and the weight is greatly reduced compared to the electronic reader that generally needs to use traditional batteries. When the super capacitor device is insufficient in power, the thin film photovoltaic cell can generate enough electricity indoors, and then the input and output unit, the first power transmission structure and the second power transmission structure are used to transmit the electricity to the super capacitor device. When the use environment is not sufficient for the thin film photovoltaic cell to generate electricity, the external power device is connected through the input and output unit to transmit the external power to the super capacitor unit, which can also provide the cholesterol liquid crystal electronic reading device for use.
