Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to displays, and more particularly to hybrid self-powered transmissive displays. [Background technology]

[0002] With the continuous improvement of display technology, new display styles are becoming more and more numerous. They have evolved from cathode ray tube (CRT) displays to thin displays such as liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs), and even LED splice displays. Display functions have evolved from standard displays to transparent backgrounds such as OLEDs and micro-light-emitting diode (MicroLED) displays. As screen resolution improves, the demand for more light-emitting sources increases, and the total power consumption of displays tends to increase. Therefore, how to save power or utilize renewable energy generated by solar power has become a hot topic. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional cholesteric liquid crystal displays (ChLCDs) and microLED displays are both transmissive and therefore suitable for use in solar-powered devices. However, combining these three displays requires new panel layouts to maximize the synergistic effects of the two displays and increase the power generation efficiency of solar-powered devices. Furthermore, because both displays and solar-powered devices exhibit periodic stripes, combining these two displays and solar-powered devices in a stacked configuration can easily result in moire patterns on the image screen, severely impacting visual quality. Given this, developing a composite display device with high power generation efficiency and reduced moire patterns is a pressing challenge facing relevant industries.

[0004] The present disclosure aims to provide a hybrid self-powered transmissive display device in which a first translucent display unit and a second translucent display unit are both disposed between a first transparent substrate and a second transparent substrate, sharing the same signal line, thereby not only saving costs and reducing thickness, but also avoiding the formation of Moiré effects due to spatial interference of stripes. Furthermore, the present disclosure also provides a device in which the first non-transmissive region and the second non-transmissive region are concentrated in the same area, thereby maximizing the area through which light can pass and further improving the power generation efficiency of the power generating module located at the bottom.

The non-light-transmitting unit surrounds the first light-transmitting display unit and the second light-transmitting display unit. The power generation module is disposed stacked on the display module. The light passes through the first transparent substrate, at least one of the first and second light-transmitting regions, and the second transparent substrate to enter the power-generating module, which converts the light into electrical energy and provides the electrical energy to at least one of the first and second light-transmitting display units.

[0012] In another example of the embodiment, the display module further includes a filter layer disposed between the first transparent substrate and the first light-transmitting region.

[0013] In another example of the embodiment, the power generation module is a silicon crystalline solar cell, a thin film solar cell, an organic solar cell, a perovskite solar cell, or a dye-sensitized solar cell.

[Figure 2]2 is a cross-sectional view of the combined self-power generation transmission display device of FIG. 1 taken along line AA'. FIG. [Figure 3] 3 is a partially transparent top view showing a power generation module of the combined self-power generation transparent display device of FIG. 2. FIG. [Figure 4] FIG. 10 is a cross-sectional view showing a combined self-power generating transmissive display device according to a second embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, several embodiments of the present disclosure will be described with reference to the drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the present disclosure. That is, in some embodiments of the present disclosure, these practical details are not necessary. In addition, to simplify the drawings, some conventional structures and elements are simply and diagrammatically shown in the drawings, and overlapping elements may be represented by the same reference numerals.

[0017] Furthermore, in this specification, when an element (or unit, module, etc.) is "connected / coupled" to another element, this may mean that the element is directly connected / coupled to the other element, or that the element is indirectly connected / coupled to the other element, i.e., there is another element between the element and the other element. Only when an element is "directly connected / coupled" to another element is it meant that there is no other element between the element and the other element. Terms such as "first," "second," and "third" are used merely to describe different elements and do not limit the elements themselves, so a first element may be replaced with a second element. Furthermore, the combinations of elements / units / circuits in this specification are not commonly known, normal, or conventional combinations in the art. Therefore, whether the elements / units / circuits themselves are conventional or not should not be used to determine whether the combinations can be easily achieved by a person skilled in the art.

[0018] 1 and 2, in which Fig. 1 is a top view showing a combined self-powered transmission display device according to a first embodiment of the present disclosure, and Fig. 2 is a cross-sectional view taken along line A-A' of the combined self-powered transmission display device of Fig. 1. As shown in Fig. 1 and Fig. 2, the combined self-powered transmission display device 10 includes a display module 100 and a power generation module 200.

[0019] 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 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 region 131 and a first non-light-transmitting region 132. The first non-light-transmitting region 132 is connected to the first light-transmitting region 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 region 141 and a second non-light-transmitting region 142. The second non-light-transmitting region 142 is connected to the second light-transmitting region 141. The first light-transmitting region 131 and the second light-transmitting region 141 are adjacent to each other. The first non-light-transmitting region 132 and the second non-light-transmitting region 142 are adjacent to each other. The first non-light-transmitting region 132 and the second non-light-transmitting region 142 are collectively provided between the first transparent substrate 110 and the second transparent substrate 120. The non-light-transmitting unit 150 surrounds the first and second light-transmitting display units 130 and 140 and may include a plurality of signal lines. These signal lines are provided between the first and second transparent substrates 110 and 120 and surround the first and second light-transmitting display units 130 and 140, so that the first and second light-transmitting display units 130 and 140 can share these signal lines.

[0020] The power generating module 200 is stacked below the display module 100. When light R sequentially passes through the first transparent substrate 110, at least one of the first translucent region 131 and the second translucent region 141, and the second transparent substrate 120 and enters the power generating module 200, the power generating module 200 converts the light R into electrical energy and provides the electrical energy to at least one of the first translucent display unit 130 and the second translucent display unit 140. In some embodiments, the combined self-powered transmissive display device 10 may further include a power storage unit (not shown), such as a rechargeable battery. The power storage unit is electrically connected to the first translucent display unit 130, the second translucent display unit 140, and the power generating module 200. The power storage unit can receive and store electrical energy from the power generating module 200 and provide the electrical energy to at least one of the first translucent display unit 130 and the second translucent display unit 140.

[0021] Therefore, the hybrid self-powered transmissive display device 10 of the present disclosure is based on a structural arrangement in which the first translucent display unit 130 and the second translucent display unit 140 are both disposed between the first transparent substrate 110 and the second transparent substrate 120, thereby saving manufacturing costs and reducing the overall thickness of the device. This structural arrangement means that the first translucent display unit 130 and the second translucent display unit 140 use the same transparent substrate in the panel manufacturing process. Furthermore, the first non-transmissive area 132 and the second non-transmissive area 142 are concentrated in the same area, for example, the area may be located at an inner corner of the non-transmissive unit 150, thereby reducing the non-transmissive area and enlarging the transparent area of ​​the hybrid self-powered transmissive display device 10, thereby maximizing the area through which light R passes and further improving the power generation efficiency of the power generating module 200.

[0022] Specifically, the first transparent substrate 110 may include a first transparent base layer 111 and a first transparent electrode layer 112. The first transparent base layer 111 is located on the top of the display module 100 and may be a rigid substrate such as a glass plate or an acrylic plate such as polymethyl methacrylate (PMMA). Alternatively, the first transparent base layer 111 may be a flexible substrate such as a substrate primarily made of polyimide (PI) or polyethylene terephthalate (PET). In addition to the materials listed above, the first transparent substrate 110 may also be a rigid or flexible substrate made of other materials. The first transparent electrode layer 112 is located below the first transparent base layer 111 and above the first translucent display unit 130 and the second translucent display unit 140. The first transparent electrode layer 112 may be made of a transparent conductive material, and the transparent conductive material may be a transparent conductive oxide (TCO) such as indium tin oxide (ITO), indium zinc oxide (IZO), poly-3,4-ethylenedioxythiophene (PEDOT), copper metal mesh film, or silver nanowire, a conductive polymer, or a metal thin film.

[0023] 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 provided above the power generation module 200. A high-transmittance adhesive layer (not shown) may be provided between the second transparent substrate layer 121 and the power generation module 200. The adhesive layer may be made of an optical clear adhesive (OCA). The thickness of the adhesive layer is only tens to hundreds of microns and is therefore negligible. Therefore, the display module 100 and the power generation module 200 appear to be in close contact with each other. The second transparent electrode layer 122 is provided above the second transparent substrate layer 121 and below the first translucent display unit 130 and the second translucent 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 .

[0024] The first translucent display unit 130 may be a reflective light-emitting device such as a cholesteric liquid crystal display (ChLCD) panel, and therefore the first transparent substrate 110, the first translucent display unit 130, and the second transparent substrate 120 may be considered as a ChLCD. The first translucent region 131 may be a pixel region (i.e., an effective pixel region of the ChLCD) that not only reflects light R to provide a screen by utilizing the properties of cholesteric liquid crystal, but also transmits the light R to the power generating module 200 located underneath. Specifically, the light R may be outdoor or indoor ambient light. When the cholesteric liquid crystal in the first translucent region 131 is in a planar state, the cholesteric liquid crystal is regularly aligned, so that most of the light R is reflected by the first translucent region 131, but a small amount of the light R can pass through the first translucent region 131 and reach the power generating module 200. When the cholesteric liquid crystal in the first light-transmitting region 131 is in a focal conic state, the alignment of the cholesteric liquid crystal is disturbed, and the first light-transmitting region 131 scatters the light R, thereby increasing the light R that passes through and reaches the power generation module 200, thereby improving power generation efficiency. The first light-transmitting display unit 130 is driven in an active manner, and the first non-light-transmitting region 132 may include a first switching element group composed of a plurality of thin-film transistors (TFTs) and electrically connected to a plurality of signal lines of the non-light-transmitting unit 150.

[0025] 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 can be considered a MicroLED display. The second light-transmitting region 141 may be a transparent substrate or a transparent plate made of a transparent material, such as, but not limited to, an ITO transparent substrate. The second non-light-transmitting region 142 may include a second switching element group and a plurality of LED dies electrically connected to a plurality of signal lines of the non-light-transmitting unit 150, and the second switching element group may be composed of a plurality of TFTs.

[0026] The non-transmitting unit 150 may have a rectangular ring shape, and its multiple signal lines may be divided into multiple scan lines for transmitting scan signals to the cholesteric liquid crystal and the LED die, and multiple data lines for transmitting data signals to the cholesteric liquid crystal and the LED die. When transmitting and allocating signals, the cholesteric liquid crystal and the MicroLED may share the scan lines and / or data lines, thereby increasing the aperture ratio of the pixel area and enabling only an external timing and driving controller to achieve the function of transmitting signals. In addition, in the stacked structure of a conventional composite display device, the multiple scan lines and multiple data lines both exhibit periodic stripes, which are prone to forming moire patterns on the image screen, further degrading visual quality. However, in the present disclosure, by sharing the scanning lines and / or data lines, the non-transparent unit 150 surrounds the first and second translucent display units 130 and 140 to avoid the screen of the images displayed in the first and second translucent areas 131 and 141, thereby effectively reducing the chance of forming moire and further ensuring the screen quality of the combined self-powered transmissive display device 10.

[0027] The first light-transmitting region 131 and the second light-transmitting region 141 may have a light-transmitting area, and the first non-light-transmitting region 132, the second non-light-transmitting region 142, and the non-light-transmitting unit 150 may have a non-light-transmitting area, with the sum of the light-transmitting area and the non-light-transmitting area being equal to the entire area of ​​the combined self-powered transmissive display device 10. The light-transmitting area is represented by A1, and the non-light-transmitting area is represented by A2, which satisfies the condition A1 / (A1+A2)≧50%, and preferably A1 / (A1+A2)≧90%. Since the translucent area through which light rays R can pass accounts for more than half of the entire area of ​​the combined self-powered transparent display device 10, the combined self-powered transparent display device 10 of the present disclosure combines the functions of reflective emission and active emission, and at the same time, the light rays R can be utilized by the power generating module 200 at the bottom, which not only reduces reflected light and improves readability in strong light, but also performs photoelectric conversion by the power generating module 200 at the bottom, providing a self-powering effect and achieving energy-saving effects.

[0028] Please continue to refer to FIG. 3, which is a partial transparent top view showing the power generation module 200 of the hybrid self-powered transmissive display device 10 of FIG. 2. As shown in FIG. 3, 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 (OSC), a perovskite solar cell (PSC), or a dye-sensitized solar cell (DSSC), or other solar cell capable of converting ambient light into electrical energy. The power generation module 200 may include an energy harvesting region 210 for converting light R into electrical energy. The energy harvesting region 210 is the effective power generation region of the power generation module 200 and actually refers to the region having a photoelectric conversion function, excluding non-power generation regions (e.g., insulating regions, prohibited regions, and conductive line regions). The energy harvesting region 210 may include a plurality of power generation units 211 arranged in an array, and each power generation unit 211 may be a solar cell. The energy harvesting region 210 may completely or partially overlap with the first light-transmitting region 131 and the second light-transmitting region 141. When the energy harvesting region 210 completely overlaps with the first light-transmitting region 131 and the second light-transmitting region 141, the effective power generation area for absorbing the light rays R can be maximized, further improving the power generation efficiency. The conductive wire region can transmit the current (corresponding electrical energy) generated in the energy harvesting region 210 to the first light-transmitting display unit 130, the second light-transmitting display unit 140, or an external circuit coupled thereto.

[0029] In FIG. 3 , the multiple power generation units 211 in the energy harvesting region 210 are arranged at intervals. Each power generation unit 211 has a unit length L. A unit pitch G1 exists between two spaced-apart power generation units 211. The power generation module 200 may further include a multiple number of conductive wires 220. These conductive wires 220 are arranged at intervals and are used to connect the multiple power generation units 211 in the energy harvesting region 210 in series. A conductor pitch G2 exists between two spaced-apart conductive wires 220. At least one of the unit length L, the unit pitch G1, and the conductor pitch G2 is equal to or greater than 1 centimeter (cm). Specifically, the power generation units 211 and the conductive wires 220 both exhibit periodic stripes, and therefore the insulating region for electrically insulating the multiple power generation units 211 also exhibits periodic stripes. In a typical display, the pixel size is typically between 50 and 300 microns (μm), and 3 to 17 stripes are visible at a viewing angle of 1 degree at a typical observation distance (e.g., 50 cm). Therefore, based on the specific periodic pitch design of the power generating module 200, for example, by controlling the unit length L, unit pitch G1, and conductor pitch G2 to 1 cm or more and making the brightness contrast of the periodic stripes smaller than 0.55, the visual sensitivity to moiré can be reduced, and further, spatial interference of the stripes on the first and second translucent display units 130 and 140 caused by the power generating module 200 can be avoided, thereby reducing the probability of the moiré effect occurring.

[0030]

[0033] Referring to Figure 4, a cross-sectional view of a hybrid self-powered transparent display device 10a according to a second embodiment of the present disclosure is shown. As shown in Figure 4, the hybrid self-powered transparent display device 10a includes a display module 100a and a power generating 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. Each element of the hybrid self-powered transparent display device 10a described above is the same as the corresponding element in the hybrid self-powered transparent display device 10 of Figure 2, and therefore detailed structure and function will not be described in detail.

[0031] The difference is that the display module 100a may further include at least one blocking member 160a. In the second embodiment, the number of blocking members 160a may be two. The blocking member 160a is provided between the first light-transmitting region 131a and the second light-transmitting region 141a to separate the first light-transmitting region 131a and the second light-transmitting region 141a. Another blocking member 160a is provided around the first non-light-transmitting region 132a and the second non-light-transmitting region 142a. In particular, the blocking member 160a may be a photo spacer (PS). In order to reduce the amount of cholesteric liquid crystal used and prevent the cholesteric liquid crystal from overflowing into the MicroLED and affecting the brightness of the active light-emitting element, the display module 100a of the present disclosure has a photospacer arranged around the MicroLED and TFTs area to prevent the cholesteric liquid crystal in the first translucent area 131a from overflowing into the second translucent area 141a, the second non-translucent area 142a, and the first non-translucent area 132a.

[0032] The display module 100a may further include a filter layer 170a, which may be a mono-color filter layer. The filter layer 170a is disposed between the first transparent substrate 110a and the first translucent region 131a. For applications requiring high color saturation, a microLED can be used to provide a three-color light source (red, green, and blue) with a narrow spectrum, thereby easily achieving the required color space. However, cholesteric liquid crystals provide a color screen primarily by reflecting ambient light. To achieve a more desirable color space representation under a very wide-spectrum light source such as sunlight, the present disclosure adds the filter layer 170a to the panel manufacturing process of the display module 100a. The filter effect of the filter layer 170a, combined with the reflection spectrum of the cholesteric liquid crystal in the first translucent region 131a, can make the screen color more saturated.

[0033] In summary, the present disclosure has the following advantages: First, compared with the conventional two-panel stacked structure, it reduces manufacturing costs and the overall device thickness. Furthermore, the first and second translucent display units use the same transparent substrate during the panel manufacturing process, which simplifies the subsequent TFT manufacturing process. Second, the cholesteric liquid crystal and the microLEDs share scan lines and / or data lines, which increases the aperture ratio of the pixel area. Third, the TFTs driving the cholesteric liquid crystal and the microLEDs are concentrated in the same area, which helps minimize non-transmissive areas and, in other words, improves transmittance and power generation efficiency. Fourth, the shared scan lines and / or data lines surround the first and second translucent display units, which effectively suppresses moire and ensures high screen quality.

[0034] Although the present disclosure has been disclosed as described above by way of embodiments, the above embodiments are not intended to limit the present disclosure, and those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure is determined by the content specified in the following claims. [Explanation of symbols]
