Technical Field
[0001] The present disclosure relates to a display device, and more particularly to a composite self-powered penetrating display device. Background Art
[0002] As display technology continues to improve, more and more new display styles are emerging. From cathode ray tube (CRT) displays to liquid crystal displays (LCD) and organic light emitting diode (OLED) thin displays, and then expanded to LED splicing displays. Display functions have evolved from general displays to transparent backgrounds, such as OLED and micro-light emitting diode (MicroLED) displays. Based on the increase in screen resolution, the demand for the number of light sources has increased, which means that the total power consumption of displays is showing an upward trend. Therefore, how to save electricity or use renewable energy generated by solar power has attracted much attention.
[0003] The existing cholesterol liquid crystal display (also called cholesteric liquid crystal display, Cholesteric Liquid Crystal Display, ChLCD) and MicroLED display both have the property of being transparent, so they can be applied to photovoltaic power generation devices. However, in order to combine the three, a novel panel configuration structure must be proposed to bring into play the multiplication effect of the two displays and increase the power generation efficiency of the photovoltaic power generation device. In addition, since the two displays and photovoltaic power generation devices mentioned above will show periodic stripes, if they are arbitrarily overlapped, it will easily form moiré patterns on the image screen, which will seriously affect the visual quality. In view of this, the development of a composite display device with high power generation efficiency and not easy to form moiré patterns has become a problem that the relevant industry players are eager to solve.

In addition, in order to simplify the drawings, some existing conventional structures and elements will be shown in a simple schematic manner in the drawings; and repeated elements may be represented by the same number.
[0056] In addition, in this article, when a certain element (or unit or module, etc.) is "connected / linked" to another element, it may refer to that the element is directly connected / linked to another element, or it may refer to that a certain element is indirectly connected / linked to another element, that is, there are other elements between the element and the other element.

Whether the elements / units / circuits themselves are existing cannot be used to determine whether their combination relationship is easy to be easily completed by technicians in the technical field.
[0057] Please also read Figure 1 , Figure 2 and Figure 3 ,in Figure 1 is a three-dimensional schematic diagram showing a composite self-powered transmission display device in a first example of a first implementation mode of the present disclosure; Figure 2 It is shown Figure 1 An exploded schematic diagram of a composite self-powered through-display device; and Figure 3 It is shown Figure 1 A top view of a composite self-powered through-display device. Figure 1 , Figure 2and Figure 3 As shown, the composite self-powered transmissive display device 100 is formed by stacking multiple layers, and includes a first light-transmitting display unit 110 , a second light-transmitting display unit 120 and a power generation module 130 .
[0058] The first light-transmitting display unit 110 is the topmost layer of the composite self-powered transmissive display device 100, and includes a first light-transmitting area 111 and a non-light-transmitting area 112. The first light-transmitting area 111 is used for a light R to enter. The non-light-transmitting area 112 is arranged around the first light-transmitting area 111. The second light-transmitting display unit 120 is the middle layer of the composite self-powered transmissive display device 100, and is stacked below the first light-transmitting display unit 110. The second light-transmitting display unit 120 includes a second light-transmitting area 121 and a peripheral area 122. The second light-transmitting area 121 overlaps with the first light-transmitting area 111. The peripheral area 122 is arranged around the second light-transmitting area 121 and overlaps with the non-light-transmitting area 112. The power generation module 130 is stacked below the second light-transmitting display unit 120. The light R sequentially penetrates the first light-transmitting area 111 and the second light-transmitting area 121, and enters the power generation module 130. The power generation module 130 is the bottom layer of the composite self-powered transmissive display device 100 , and converts the light R into electric energy P to provide the electric energy P to the first light-transmissive display unit 110 and the second light-transmissive display unit 120 .
[0059] Specifically, a high-transmittance adhesive layer (not shown) is provided between the first light-transmittance display unit 110 and the second light-transmittance display unit 120, and another high-transmittance adhesive layer (not shown) is provided between the second light-transmittance display unit 120 and the power generation module 130. Both adhesive layers can be made of optical clear adhesive (OCA). Since the thickness of the adhesive layer is only between tens of microns and hundreds of microns, it can be ignored, so the first light-transmittance display unit 110, the second light-transmittance display unit 120 and the power generation module 130 are tightly fitted.
[0060] The first light-transmissive display unit 110 may be an active light-emitting panel, such as a micro light-emitting diode (MicroLED) panel.
[0061] The first light-transmitting region 111 is a transparent substrate or a transparent plate formed of a transparent material. The first light-transmitting region 111 can be, for example but not limited to, a transparent substrate made of indium tin oxide (ITO).
[0062] The non-light-transmitting area 112 includes a first area 1121 and a second area 1122 that are connected to each other and opaque, wherein the first area 1121 may include a plurality of LED dies and a plurality of thin-film transistors (TFTs), and the second area 1122 overlaps with the peripheral area 122 and is presented as a rectangular frame, and may include a plurality of scan lines (Scan lines) for transmitting scan signals to the LED dies and a plurality of data lines (Data lines) for transmitting data signals to the LED dies. The first area 1121 is centrally arranged at a corner position inside the second area 1122, thereby reducing the opaque area of the first light-transmitting display unit 110 and enlarging the transparent area, so that the area (i.e., the area that allows light R to penetrate) is reduced. Figure 3 The area of the first light-transmitting region 111 is increased.
[0063] The second light-transmitting display unit 120 can be a reflective light-emitting panel, such as a cholesteric liquid crystal display (ChLCD) panel, and its driving mode is passive, so it does not have a TFT element. The second light-transmitting area 121 is a pixel area (i.e., an effective pixel area of ChLCD), which uses the characteristics of cholesteric liquid crystal to reflect light R and provide a picture, and also allows light R to penetrate to the power generation module 130 located at the bottom. In detail, the light R can be outdoor or indoor ambient light. When the second light-transmitting display unit 120 is in a planar arrangement state (Planarstate), the cholesteric liquid crystal is arranged neatly, so that most of the light R is reflected by the second light-transmitting area 121, but a small part of the light R can still penetrate the second light-transmitting area 121 to the power generation module 130. When the second light-transmitting display unit 120 is in a focal conic arrangement state (Focal conic state), the cholesteric liquid crystal is arranged chaotically, and the second light-transmitting area 121 scatters the light R, so that the light R that can penetrate to the power generation module 130 increases, resulting in improved power generation efficiency. The peripheral area 122 can be used as an isolation area. The aforementioned isolation area is a non-conductive isolation layer and is arranged around the second light-transmitting area 121. It is made of a transparent material, wherein the transparent material can be, for example, but not limited to, glass. In this way, the composite self-powered transmission display device 100 of the present disclosure has both active luminescence and reflective luminescence functions. At the same time, the light R can be used by the bottom power generation module 130, which can not only reduce reflected light and improve readability under strong light, but also can achieve self-power generation effect by photoelectric conversion with the help of the bottom power generation module 130, thereby achieving energy saving effect.
[0064] In addition, a total area of the first light-transmitting area 111 and the non-light-transmitting area 112 may be A1 (i.e., representing the top area of the first light-transmitting display unit 110), and an overlapping area of the first light-transmitting area 111 and the second light-transmitting area 121 is A2, which satisfies the following conditions: A2 / A1≥50%, and preferably, A2 / A1≥90%. Thus, the composite self-powered transmissive display device 100 of the present disclosure increases the light-transmitting area through the structural configuration in which the first light-transmitting area 111 overlaps the second light-transmitting area 121, so as to effectively reduce the area of shielding the light R, thereby improving the power generation efficiency of the power generation module 130. In this embodiment, the first light-transmitting area 111 and the second light-transmitting area 121 may overlap completely or partially. If the first light-transmitting area 111 and the second light-transmitting area 121 overlap completely, the overlapping area of the first light-transmitting area 111 and the second light-transmitting area 121 can be maximized to achieve high power generation efficiency.
[0065] In addition, in the existing composite display device, multiple scanning lines and multiple data lines will present periodic stripes, which will easily form moiré patterns on the image screen, thereby reducing the visual quality. However, the present disclosure, through the overlapping configuration of the first light-transmitting area 111 and the second light-transmitting area 121 and the overlapping configuration of the non-light-transmitting area 112 and the peripheral area 122, makes the non-light-transmitting area 112 provided with multiple scanning lines and multiple data lines avoid the image screen presented by the first light-transmitting area 111 and the second light-transmitting area 121, thereby effectively reducing the chance of moiré patterns being formed, thereby ensuring the image quality of the composite self-powered transmission display device 100.
[0066] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 4 It is shown Figure 1 A partially transparent top view of a power generation module of a composite self-powered through-display device. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the power generation module 130 may be, for example but not limited to, a silicon crystalline solar cell, a thin film solar cell, an organic solar cell (OPV), a perovskite solar cell (PSC) or a dye sensitized solar cell (DSSC), or other solar cells that can convert ambient light into electrical energy P. The power generation module 130 may include an energy hunting area 131 for converting light R into electrical energy P. The energy hunting area 131 is an effective power generation area of the power generation module 130, which actually refers to an area with a light-to-electricity conversion function, and non-power generation areas (such as insulating areas, forbidden areas, and wire areas) need to be deducted. The energy hunting area 131 includes a plurality of power generation units 1311 arranged in an array, and each power generation unit 1311 may be a solar cell. The energy hunting area 131 may completely overlap or partially overlap with the first light-transmitting area 111 and the second light-transmitting area 121. If the energy hunting area 131 completely overlaps with the first light-transmitting area 111 and the second light-transmitting area 121, the effective power generation area for absorbing light R can be maximized, thereby improving the power generation efficiency. The aforementioned conductive line area can transmit the current (corresponding to the electric energy P) generated by the energy hunting area 131 to the first light-transmitting display unit 110, the second light-transmitting display unit 120 or an external circuit coupled thereto.
[0067] The composite self-powered transparent display device 100 may further include a power storage unit 140, such as a rechargeable battery. The power storage unit 140 is electrically connected to the first light-transmitting display unit 110, the second light-transmitting display unit 120, and the power generation module 130. The power storage unit 140 receives and stores electric energy P from the wire area of the power generation module 130, and provides the electric energy P to the first light-transmitting display unit 110 and the second light-transmitting display unit 120.
[0068] At Figure 4In the energy hunting area 131, a plurality of power generation units 1311 are arranged at intervals from each other. Each power generation unit 1311 has a unit length L. A unit spacing G1 is provided between two power generation units 1311 spaced from each other. In addition, the power generation module 130 may further include a plurality of conductive wires 1312. The plurality of conductive wires 1312 are arranged at intervals from each other and are used to connect the plurality of power generation units 1311 in the energy hunting area 131 in series. A wire spacing G2 is provided between two conductive wires 1312 spaced from each other. At least one of the unit length L, the unit spacing G1 and the wire spacing G2 is greater than or equal to 1 centimeter (cm). In detail, the power generation units 1311 and the conductive wires 1312 will both present periodic stripes, and even the insulating area used to electrically isolate the plurality of power generation units 1311 will present periodic stripes. The common pixel size of a general display is between 50 and 300 micrometers (μm), and 3 to 17 stripes can be seen at a 1 degree viewing angle at a normal observation distance (e.g., 50 cm). Therefore, as long as the unit length L, the unit spacing G1 and the wire spacing G2 are controlled to be above 1 cm, and the light-dark contrast of the periodic stripes is less than 0.55, the sensitivity of the human eye to the moiré pattern is reduced, thereby avoiding the power generation module 130 from causing stripe spatial interference to the first light-transmitting display unit 110 and the second light-transmitting display unit 120, and reducing the probability of the occurrence of the moiré effect.
[0069] See also Figure 5 , which is a schematic diagram of an exploded view of a composite self-powered transmission display device in a second embodiment according to the first embodiment of the present disclosure. Figure 5 As shown, the composite self-powered transparent display device 200 includes a first light-transmitting display unit 210, a second light-transmitting display unit 220, and a power generation module 230. The first light-transmitting display unit 210 and the power generation module 230 are respectively connected to Figure 2 The first light-transmissive display unit 110 and the power generation module 130 are the same components, so their detailed structures and functions are not described in detail.
[0070] and Figure 2The difference is that the second light-transmitting display unit 220 can be a reflective light-emitting panel, such as a ChLCD panel, and its driving method is active, so it can have TFT elements. The second light-transmitting display unit 220 includes a second light-transmitting area 221 and a peripheral area 222 arranged around the second light-transmitting area 221. The second light-transmitting area 221 overlaps with the first light-transmitting area 211 of the first light-transmitting display unit 210, and overlaps with the energy-hunting area 231 of the power generation module 230. The peripheral area 222 overlaps with the non-light-transmitting area 212 of the first light-transmitting display unit 210. In detail, the non-light-transmitting area 212 can include a plurality of first scan lines and a plurality of first data lines. The peripheral area 222 can serve as another non-light-transmitting area, and includes a third area 2221 and a fourth area 2222 that are connected to each other and opaque, wherein the third area 2221 can be provided with a plurality of TFT elements, and the fourth area 2222 is presented as a rectangular frame, and can include a plurality of second scan lines and a plurality of second data lines. The third area 2221 is concentrated at a corner position inside the fourth area 2222, thereby reducing the opaque area of the second light-transmitting display unit 220 and enlarging the transparent area. Since the upper opaque first scan line and the first data line overlap the lower opaque second scan line and the second data line, and the first light-transmitting area 211, the second light-transmitting area 221 and the energy-hunting area 231 overlap each other, the light penetration area is maximized to increase the light aperture ratio, which can not only improve the power generation efficiency of the power generation module 230, but also avoid the formation of moiré effect due to the spatial interference of stripes on the upper and lower panels.

The power generation module 330 and the power storage unit 340 are respectively connected to Figure 1 The power generation module 130 and the power storage unit 140 are the same components, so their detailed structures and functions are not further described.
[0072] The first light-transmitting display unit 310 includes a first light-transmitting area 311 and a peripheral area 312. The first light-transmitting area 311 is used for light R to enter. The peripheral area 312 is arranged around the first light-transmitting area 311. The second light-transmitting display unit 320 is stacked below the first light-transmitting display unit 310, and includes a second light-transmitting area 321 and a non-light-transmitting area 322. The second light-transmitting area 321 overlaps with the first light-transmitting area 311. The non-light-transmitting area 322 is arranged around the second light-transmitting area 321 and overlaps with the peripheral area 312. The power generation module 330 is stacked below the second light-transmitting display unit 320, and the energy-hunting area 331 of the power generation module 330 overlaps with the first light-transmitting area 311 and the second light-transmitting area 321. The light R penetrates the first light-transmitting area 311 and the second light-transmitting area 321 in sequence and enters the power generation module 330. The energy-collecting region 331 of the power generation module 330 converts the light R into electric energy P, so as to provide the electric energy P to the first light-transmitting display unit 310 and the second light-transmitting display unit 320 .
[0073] In detail, the first light-transmitting display unit 310 can be a reflective light-emitting panel, such as a ChLCD panel, and its driving mode is passive, so it does not have a TFT element. The first light-transmitting area 311 is a pixel area (i.e., an effective pixel area of the ChLCD), which utilizes the characteristics of cholesterol liquid crystal to reflect light R to provide a picture, and also allows light R to penetrate into the energy-hunting area 331 of the power generation module 330. The peripheral area 312 can be used as an isolation area, which is a non-conductive isolation layer and is arranged around the first light-transmitting area 311, and is composed of a transparent material, wherein the transparent material can be, for example, but not limited to, glass.
[0074] The second light-transmitting display unit 320 may be an active light-emitting panel, such as a MicroLED panel. The second light-transmitting area 321 is a transparent substrate or a transparent plate formed of a transparent material, such as an ITO transparent substrate. The non-light-transmitting area 322 includes a first area 3221 and a second area 3222 that are connected to each other and opaque. The first area 3221 may include a plurality of LED chips and a plurality of TFTs. The second area 3222 overlaps with the peripheral area 312 and appears as a rectangular frame, and may include a plurality of scan lines and a plurality of data lines. The first area 3221 is centrally arranged at a corner position on the inner side of the second area 3222, thereby reducing the opaque area of the second light-transmitting display unit 320 and enlarging the transparent area, so that the area that allows light R to penetrate is increased.
[0075] In addition, the total area of the first light-transmitting area 311 and the peripheral area 312 can be A1 (i.e., representing the top area of the first light-transmitting display unit 310), and the overlapping area of the first light-transmitting area 311 and the second light-transmitting area 321 is A2, which satisfies the following conditions: A2 / A1≥50%, and preferably, A2 / A1≥90%. In this way, the composite self-powered transmissive display device 300 of the present disclosure increases the light-transmitting area through the structural configuration of the first light-transmitting area 311 overlapping the second light-transmitting area 321, so as to effectively reduce the area of shielding the light R, thereby improving the power generation efficiency of the power generation module 330.
[0076] Specifically, Figure 6 The first light-transmitting display unit 310 and the second light-transmitting display unit 320 of the composite self-powered transmissive display device 300 are exchanged to form Figure 1 In other words, Figure 6 The first light-transmitting display unit 310 and Figure 1 The second light-transmitting display unit 120 is the same element, and the second light-transmitting display unit 320 and the first light-transmitting display unit 110 are also the same element. Therefore, the composite self-powered transmissive display device 300 of the present disclosure also has the functions of reflective luminescence and active luminescence, and has a self-powered effect by means of photoelectric conversion by means of the energy-hunting area 331 of the power generation module 330. In addition, the composite self-powered transmissive display device 300 of the present disclosure, through the overlapping configuration of the first light-transmitting area 311 and the second light-transmitting area 321 and the overlapping configuration of the peripheral area 312 and the non-light-transmitting area 322, allows the non-light-transmitting area 322 provided with multiple scan lines and multiple data lines to avoid the image screen presented by the first light-transmitting area 311 and the second light-transmitting area 321, thereby effectively reducing the chance of moiré formation and thus ensuring the image quality.
[0077] Please also read Fig. 9 and Fig.10 ,in Fig. 9 is an exploded schematic diagram showing a composite self-powered transmission display device in a second example of a second embodiment of the present disclosure; and Fig.10 It is shown Fig. 9 A top view of a composite self-powered through-display device. Fig. 9 and Fig.10 As shown, the composite self-powered transmissive display device 400 includes a first light-transmitting display unit 410, a second light-transmitting display unit 420, and a power generation module 430. The second light-transmitting display unit 420 and the power generation module 430 are respectively connected to Figure 7 The second light-transmissive display unit 320 and the power generation module 330 are the same components, so their detailed structures and functions are not described in detail.
[0078] and Figure 7The difference is that the first light-transmitting display unit 410 can be a reflective light-emitting panel, such as a ChLCD panel, and its driving method is active, so it can have TFT elements. The first light-transmitting display unit 410 includes a first light-transmitting area 411 and a peripheral area 412 arranged around the first light-transmitting area 411. The first light-transmitting area 411 overlaps with the second light-transmitting area 421 of the second light-transmitting display unit 420, and overlaps with the energy-hunting area 431 of the power generation module 430. The peripheral area 412 overlaps with the non-light-transmitting area 422 of the second light-transmitting display unit 420. In detail, the peripheral area 412 can serve as another non-light-transmitting area, and this other non-light-transmitting area can include multiple first scan lines and multiple first data lines, and the non-light-transmitting area 422 can include multiple second scan lines and multiple second data lines. Since the upper opaque first scan line and the first data line overlap the lower opaque second scan line and the second data line, and the first light-transmitting area 411, the second light-transmitting area 421 and the energy-hunting area 431 overlap with each other, the light penetration area is maximized and the light aperture ratio is improved, which not only improves the power generation efficiency of the power generation module 430, but also avoids the formation of a moiré effect due to spatial interference of stripes between the upper and lower panels.
[0079] In summary, the present disclosure has the following advantages: First, it has the functions of active luminescence and reflective luminescence to realize two different display technologies, and can achieve self-generating effect by means of photoelectric conversion with the aid of power generation modules. Second, the structural configuration of the first light-transmitting area overlapping the second light-transmitting area maximizes the area through which light can penetrate, thereby improving the power generation efficiency of the power generation module. Third, the overlapping configuration of the first light-transmitting area and the second light-transmitting area and the overlapping configuration of the non-light-transmitting area with scanning lines and data lines and the peripheral area effectively reduces the chance of moiré formation, thereby ensuring the picture quality.
