Description

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 the photovoltaic power generation device will both show periodic stripes, if the two displays and the photovoltaic power generation device are combined in a stacked manner, it will easily form a moiré pattern 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.

[0045] The following will describe multiple embodiments of the present disclosure with reference to the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. 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.

[0046] 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. When it is explicitly stated that a certain element is "directly connected / linked" to another element, it means that there are no other elements between the element and the other element. The terms first, second, third, etc. are only used to describe different elements, and there is no restriction on the elements themselves. Therefore, the first element can also be renamed as the second element. Moreover, the combination of elements / units / circuits in this article is not a generally known, conventional or existing combination in this field. 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.

[0047] Please also read Figure 1 and Figure 2 ,in Figure 1 is a top view showing a composite self-powered transmission display device according to a first embodiment of the present disclosure; and Figure 2 It is shown Figure 1 A cross-sectional view of the composite self-powered through-display device along the tangent line A-A'. Figure 1 and Figure 2 As shown, the hybrid self-powered transparent display device 10 includes a display module 100 and a power generation module 200 .

[0048] The display module 100 includes a first transparent substrate 110, a second transparent substrate 120, a first light-transmitting display unit 130, a second light-transmitting display unit 140 and a non-light-transmitting unit 150. The first transparent substrate 110 and the second transparent substrate 120 are disposed opposite to each other. The first light-transmitting display unit 130 is disposed between the first transparent substrate 110 and the second transparent substrate 120, and includes a first light-transmitting area 131 and a first non-light-transmitting area 132. The first non-light-transmitting area 132 is connected to the first light-transmitting area 131. The second light-transmitting display unit 140 is disposed between the first transparent substrate 110 and the second transparent substrate 120, and includes a second light-transmitting area 141 and a second non-light-transmitting area 142. The second non-light-transmitting area 142 is connected to the second light-transmitting area 141. The first light-transmitting area 131 and the second light-transmitting area 141 are adjacent to each other. The first non-light-transmitting area 132 and the second non-light-transmitting area 142 are adjacent to each other and are centrally disposed in an area between the first transparent substrate 110 and the second transparent substrate 120. The non-light-transmitting unit 150 surrounds the first light-transmitting display unit 130 and the second light-transmitting display unit 140 and may include a plurality of signal lines. The plurality of signal lines are disposed between the first transparent substrate 110 and the second transparent substrate 120 and are disposed around the first light-transmitting display unit 130 and the second light-transmitting display unit 140, so that the first light-transmitting display unit 130 and the second light-transmitting display unit 140 can share the plurality of signal lines.

[0049] The power generation module 200 is stacked below the display module 100. When a light R sequentially penetrates the first transparent substrate 110, at least one of the first light-transmitting area 131 and the second light-transmitting area 141, and the second transparent substrate 120 and enters the power generation module 200, the power generation module 200 converts the light R into electrical energy to provide electrical energy to at least one of the first light-transmitting display unit 130 and the second light-transmitting display unit 140. In some embodiments, the composite self-powered transmissive display device 10 may further include a power storage unit (not shown separately), such as a rechargeable battery. The power storage unit is electrically connected to the first light-transmitting display unit 130, the second light-transmitting display unit 140, and the power generation module 200. The power storage unit can receive and store electrical energy from the power generation module 200, and provide electrical energy to at least one of the first light-transmitting display unit 130 and the second light-transmitting display unit 140.

[0050] Thus, the composite self-powered transmissive display device 10 of the present disclosure is based on the structural configuration that the first light-transmissive display unit 130 and the second light-transmissive display unit 140 are both disposed between the first transparent substrate 110 and the second transparent substrate 120, which means that the first light-transmissive display unit 130 and the second light-transmissive display unit 140 use the same transparent substrate in the panel process, thereby saving manufacturing costs and reducing the overall thickness of the device. In addition, since the first non-light-transmissive area 132 and the second non-light-transmissive area 142 are concentrated in the same area, for example, the aforementioned area can be located at a corner position on the inner side of the non-light-transmissive unit 150, thereby reducing the opaque area in the composite self-powered transmissive display device 10 and enlarging the transparent area, so that the area for the light R to penetrate is maximized, thereby improving the power generation efficiency of the power generation module 200.

[0051] Specifically, the first transparent substrate 110 may include a first transparent substrate layer 111 and a first transparent electrode layer 112. The first transparent substrate layer 111 is located on the top of the display module 100 and may be a rigid substrate (Rigid Substrate), which is, for example, a glass plate or polymethyl methacrylate (PMMA), that is, an acrylic plate. Alternatively, the first transparent substrate layer 111 may also be a flexible substrate (Flexible Substrate), which is, for example, a substrate made of a main material of polyimide (PI) or polyethylene terephthalate (PET). In addition to the materials exemplified above, the first transparent substrate 110 may also be a rigid substrate or a flexible substrate made of other materials. The first transparent electrode layer 112 is disposed below the first transparent substrate layer 111 and above the first light-transmitting display unit 130 and the second light-transmitting display unit 140. The first transparent electrode layer 112 may be made of a transparent conductive material, which may be a transparent conductive oxide (TCO), a conductive polymer or a metal thin film, such as indium tin oxide (ITO), indium zinc oxide (IZO), poly-3,4-ethylenedioxythiophene (PEDOT), a copper metal mesh film or a silver nanowire.

[0052] The second transparent substrate 120 may include a second transparent substrate layer 121 and a second transparent electrode layer 122. The second transparent substrate layer 121 is located at the bottom of the display module 100 and is disposed above the power generation module 200. An adhesive layer (not shown separately) with high transmittance may be provided between the second transparent substrate layer 121 and the power generation module 200. The adhesive layer may be composed 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 power generation module 200 and the display module 100 can be closely attached. The second transparent electrode layer 122 is disposed above the second transparent substrate layer 121 and below the first light-transmitting display unit 130 and the second light-transmitting display unit 140. In the first embodiment, the material of the second transparent substrate layer 121 is the same as the material of the first transparent substrate layer 111, and the material of the second transparent electrode layer 122 is the same as the material of the first transparent electrode layer 112.

[0053] The first light-transmitting display unit 130 may be a reflective light-emitting element, such as a cholesterol liquid crystal display (or cholesteric liquid crystal display (ChLCD)) panel, so the first transparent substrate 110, the first light-transmitting display unit 130 and the second transparent substrate 120 may be regarded as a ChLCD. The first light-transmitting area 131 may be a pixel area (i.e., an effective pixel area of ​​the ChLCD), which utilizes the characteristics of cholesterol liquid crystals to not only reflect the light R to provide a picture, but also allow the light R to penetrate to the power generation module 200 located at the bottom. In detail, the light R may be outdoor or indoor ambient light. When the cholesterol liquid crystals in the first light-transmitting area 131 are in a planar state, the cholesterol liquid crystals are arranged neatly, so that most of the light R is reflected by the first light-transmitting area 131, but a small part of the light R can still penetrate the first light-transmitting area 131 to the power generation module 200. When the cholesterol liquid crystal in the first light-transmitting area 131 is in a focal conic state, the cholesterol liquid crystal is arranged in a disordered manner, and the first light-transmitting area 131 scatters the light R, so that the light R that can penetrate into the power generation module 200 increases, resulting in improved power generation efficiency. The first light-transmitting display unit 130 is driven in an active manner, and the first non-light-transmitting area 132 may include a first switch element group electrically connected to a plurality of signal lines of the non-light-transmitting unit 150, and the first switch element group is composed of a plurality of thin-film transistors (TFTs).

[0054] The second light-transmitting display unit 140 may be an active light-emitting element, such as a micro light-emitting diode (MicroLED) panel, so the first transparent substrate 110, the second light-transmitting display unit 140 and the second transparent substrate 120 may be regarded as a MicroLED display. The second light-transmitting area 141 is a transparent substrate or a transparent plate formed of a transparent material. The second light-transmitting area 141 may be, for example but not limited to, a transparent substrate prepared by ITO. The second light-impermeable area 142 may include a second switch element group electrically connected to multiple signal lines of the light-impermeable unit 150 and multiple LED dies, wherein the second switch element group is composed of multiple TFTs.

[0055] The non-light-transmitting unit 150 may be in the shape of a rectangular ring, and its multiple signal lines may be divided into multiple scan lines (Scan lines) for transmitting scan signals to cholesterol liquid crystal and LED crystals and multiple data lines (Data lines) for transmitting data signals to cholesterol liquid crystal and LED crystals. In terms of signal transmission and distribution, the cholesterol liquid crystal and MicroLED may share scan lines and / or data lines, which may increase the aperture ratio of the pixel area, and the signal transmission function may be achieved only through external timing and driving controllers. In addition, in the stacked structure of the existing composite display device, multiple scan lines and multiple data lines will present periodic stripes, which may easily form a moiré pattern on the image screen, thereby reducing the visual quality. However, the present disclosure utilizes a shared scanning line and / or data line to surround the first light-transmitting display unit 130 and the second light-transmitting display unit 140 with the non-light-transmitting unit 150 to avoid the image displayed by the first light-transmitting area 131 and the second light-transmitting area 141, thereby effectively reducing the chance of moiré formation and ensuring the image quality of the composite self-powered transmissive display device 10.

[0056] Furthermore, the first light-transmitting area 131 and the second light-transmitting area 141 may have a light-transmitting area, and the first non-light-transmitting area 132, the second non-light-transmitting area 142 and the non-light-transmitting unit 150 may have a non-light-transmitting area, wherein the sum of the aforementioned light-transmitting area and the aforementioned non-light-transmitting area is equal to the overall area of ​​the composite self-powered penetrating display device 10. The light-transmitting area is represented by A1, and the non-light-transmitting area is represented by A2, which satisfies the following conditions: A1 / (A1+A2)≥50%, and preferably, A1 / (A1+A2)≥90%. Since the light-transmitting area for the light R to penetrate occupies more than half of the overall area of ​​the composite self-powered penetrating display device 10, the composite self-powered penetrating display device 10 of the present disclosure has the functions of both reflective luminescence and active luminescence, and at the same time, the light R can be used by the power generation module 200 at the bottom, which can not only reduce the reflected light and improve the readability under strong light, but also can be used for photoelectric conversion by the power generation module 200 at the bottom to have a self-powered effect, thereby achieving an energy-saving effect.

[0057] Please continue reading Figure 3 , which is shown Figure 2 A partially transparent top view of a power generation module of a composite self-powered through-display device. Figure 3 As shown, the power generation module 200 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. The power generation module 200 may include an energy hunting area 210 for converting light R into electrical energy. The energy hunting area 210 is an effective power generation area of ​​the power generation module 200, 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 210 includes a plurality of power generation units 211 arranged in an array, and each power generation unit 211 may be a solar cell. The energy hunting area 210 and the first light-transmitting area 131 and the second light-transmitting area 141 may completely overlap or partially overlap. If the energy hunting area 210 and the first light-transmitting area 131 and the second light-transmitting area 141 completely overlap, the effective power generation area for absorbing light R can be maximized, thereby improving the power generation efficiency. The aforementioned wire area can transmit the current (corresponding to the electric energy) generated by the energy hunting area 210 to the first light-transmitting display unit 130, the second light-transmitting display unit 140 or an external circuit coupled thereto.

[0058] At Figure 3In the energy hunting area 210, a plurality of power generation units 211 are arranged at intervals from each other. Each power generation unit 211 has a unit length L. A unit spacing G1 is provided between two power generation units 211 spaced from each other. In addition, the power generation module 200 may further include a plurality of conductive wires 220. The plurality of conductive wires 220 are arranged at intervals from each other and are used to connect the plurality of power generation units 211 in the energy hunting area 210 in series. A wire spacing G2 is provided between two conductive wires 220 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 211 and the conductive wires 220 will both present periodic stripes, and even the insulating area used to electrically isolate the plurality of power generation units 211 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, based on the specific periodic spacing design of the power generation module 200, for example, as long as the unit length L, the unit spacing G1 and the wire spacing G2 are controlled to be above 1 cm, so that 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 200 from causing stripe spatial interference to the first light-transmitting display unit 130 and the second light-transmitting display unit 140, and reducing the probability of the occurrence of the moiré effect.

[0059] See also Figure 4 , which is a cross-sectional view showing a composite self-powered transmission display device according to a second embodiment of the present disclosure. Figure 4 As shown, the composite self-powered transmission display device 10a includes a display module 100a and a power generation module 200a. The display module 100a includes a first transparent substrate 110a, a second transparent substrate 120a, a first light-transmitting display unit 130a, a second light-transmitting display unit 140a and a non-light-transmitting unit 150a. The components of the composite self-powered transmission display device 10a mentioned above are all the same as Figure 2 The corresponding elements in the composite self-powered transmissive display device 10 are the same, so the detailed structure and function are not further described.

[0060] The difference is that the display module 100a may further include at least one blocking member 160a. In the second embodiment, the number of the blocking members 160a may be two. The blocking member 160a is disposed between the first light-transmitting area 131a and the second light-transmitting area 141a to separate the first light-transmitting area 131a from the second light-transmitting area 141a. Another blocking member 160a is disposed around the first non-light-transmitting area 132a and the second non-light-transmitting area 142a. In detail, the blocking member 160a may be a photo spacer (PS). In order to reduce the amount of cholesterol liquid crystal used and prevent the cholesterol liquid crystal from overflowing to the MicroLED and affecting the brightness of the active light-emitting element, the display module 100a of the present disclosure is configured with photo spacers around the MicroLED and TFTs area to prevent the cholesterol liquid crystal in the first light-transmitting area 131a from overflowing to the second light-transmitting area 141a, the second non-light-transmitting area 142a and the first non-light-transmitting area 132a.

[0061] In addition, the display module 100a may further include a filter layer 170a, and it may be a monochromatic filter layer. The filter layer 170a is disposed between the first transparent substrate 110a and the first light-transmitting area 131a. For applications with higher color saturation requirements, the use of MicroLED can provide a narrower spectrum of three-color light sources (red, green and blue), and it is easy to meet the requirements of the color gamut space, but cholesterol liquid crystals mainly rely on the reflection of ambient light to provide a color picture. When under a very wide spectrum light source such as sunlight. In order to achieve better color gamut space performance, the present disclosure adds a filter layer 170a to the panel process of the display module 100a, and its filtering effect can be matched with the reflection spectrum of the cholesterol liquid crystal in the first light-transmitting area 131a, so that the color of the picture presents a more saturated reflected light.

[0062] In summary, the present disclosure has the following advantages: First, compared with the existing two-panel stacking structure, it saves more manufacturing costs and reduces the thickness of the overall device. In addition, in the panel process, the first light-transmitting display unit and the second light-transmitting display unit use the same transparent substrate, which is also convenient for the subsequent TFTs process. Second, the cholesterol liquid crystal and MicroLED share scanning lines and / or data lines, which can increase the aperture ratio of the pixel area. Third, the TFTs that drive the cholesterol liquid crystal and MicroLED are concentrated in the same area, which is conducive to minimizing the non-light-transmitting area; in other words, it is conducive to improving the transmittance and improving the power generation efficiency. Fourth, by sharing scanning lines and / or data lines, they surround the first light-transmitting display unit and the second light-transmitting display unit, so as to effectively suppress the formation of moiré patterns and thus ensure the picture quality.

[0063] Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make various changes and modifications without departing from the concept and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be based on what is defined in the claims.
