[0093] Figure 1 FIG. 1 is a schematic diagram of a transparent display device according to an embodiment of the present disclosure. Figure 1In the embodiment, the transparent display device 100 has, for example, an exposed area 100A and a non-exposed area 100B, wherein the non-exposed area 100B may partially surround the exposed area 100A. In some embodiments, the non-exposed area 100B is generally distributed around the local periphery of the transparent display device 100, and may not completely surround the exposed area 100A. In some embodiments, the exposed area 100A may extend to the local edge of the transparent display device 100 without being completely surrounded by the non-exposed area 100B. The non-exposed area 100B may be understood as a portion of the transparent display device 100 that can be surrounded by the frame ( Figure 1 The exposed area 100A is an area that is hidden or can be installed inside the frame (not shown). In some embodiments, during actual use, the non-exposed area 100B can be shielded and not directly seen by the user. The exposed area 100A can be understood as the area of ​​the transparent display device 100 that can be exposed during actual use, but the present disclosure does not exclude the situation where the exposed area 100A is temporarily shielded during use. For example, during actual use, the transparent display device 100 can have different usage states. In some usage states, the exposed area 100A can be at least partially exposed to allow the user to see it directly, while in other usage states, the exposed area 100A that can be seen by the user can be partially or completely shielded. In other words, when the transparent display device 100 is in use, the exposed area 100A may be shielded or exposed, but the non-exposed area 100B will be shielded regardless of the usage state. For ease of understanding, Figure 1 In the subsequent figures, the X direction, Y direction and Z direction are used to present the orientation of the transparent display device 100 in the respective figures. The Y direction may be perpendicular to the upper surface or the lower surface of the transparent display device 100, and the X direction and the Z direction may be parallel to the upper surface or the lower surface of the transparent display device 100. The Y direction may be perpendicular to the X direction and the Z direction, and the X direction may be perpendicular to the Z direction. In this embodiment, the plane of the transparent display device 100 is oriented to the plane formed by the X direction and the Z direction for description.

[0094] The transparent display device 100 may include at least a display panel 120 and a driving device DR. The display panel 120 may include a plurality of pixels PX. The pixel PX is, for example, located in the exposed area 100A and the driving device DR is located in the non-exposed area 100B. The driving device DR is suitable for driving the pixel PX. The pixel PX can be used to emit light to display a picture, and the driving device DR can be used to transmit the signal required by the pixel PX to the pixel. In some embodiments, the pixel PX may include, for example, a liquid crystal (Liquid Crystal), an organic light emitting diode (Organic Light Emitting Diode, OLED), an inorganic light emitting diode (Inorganic Light Emitting Diode, LED), a sub-millimeter light emitting diode (Mini-LED), a micro-light emitting diode (Micro-LED), a quantum dot (Quantum Dot, QD), a quantum dot diode (QLED / QDLED), electrophoresis (Electro-Phoretic), fluorescence (Fluorescence), phosphorescence (Phosphor), other suitable materials or a combination of the above materials, but the present disclosure is not limited thereto. In some embodiments, a plurality of pixels PX may emit light of multiple colors to achieve a colorful display effect. The driving element DR may be an opaque component, so arranging the driving element DR in the non-exposed area 100B can reduce the area of ​​the driving element DR in the exposed area 100A of the transparent display device 100 to form an opaque area, thereby helping to improve the overall transmittance of the exposed area 100A and / or increase the area of ​​the exposed area 100A that can present a transparent effect. The transparent display device disclosed herein can be applied to the fields of architecture, automobiles, interior decoration, signs, windows or optical devices, but is not limited thereto.

[0095] exist Figure 1 In the transparent display device 100, the display panel 120 can be configured on the carrier 110. The carrier 110 is, for example, a plate-like object with light transmittance and sufficient supporting properties. In some embodiments, the material of the carrier 110 may include glass, quartz, sapphire, polymer (such as polyimide (PI), polyethyleneterephthalate (PET)) and / or other suitable materials, or combinations of the above, etc., the present disclosure is not limited to this, in some embodiments, the carrier 110 can be a single-layer or multi-layer structure. Specifically, the display panel 120 can be attached or manufactured on the carrier 110. In some embodiments, the display panel 120 can be a transparent display panel. That is, the display panel 120 has a certain transmittance so that the user can see the scenery behind the display panel 120. In some embodiments, the area range of the display panel 120 can be less than or equal to the area of ​​the carrier 110, but is not limited to this.

[0096] The display panel 120 may have a display area 120A and a non-display area 120B, wherein the pixels PX are arranged in the display area 120A to display images in the display area 120A, and the non-display area 120B may surround the display area 120A. The display area 120A overlaps the exposed area 100A of the transparent display device 100, and at least a portion of the non-display area 120B overlaps the exposed area 100A and another portion overlaps the non-exposed area 100B. The non-display area 120B may include a bonding area BR located in the non-exposed area 100B. In addition, in addition to the pixels PX, the display panel 120 may also be provided with data connection lines SC1 and scan connection lines SC2. Specifically, signal lines (not shown) corresponding to the pixels PX, such as scan lines and data lines, are arranged in the display area 120A, and the data connection lines SC1 and the scan connection lines SC2 may connect these signal lines located in the display area 120A. The data connection lines SC1 and the scan connection lines SC2 may extend outward from the edge of the display region 120A and at least partially extend to the bonding region BR.

[0097] The driving element DR may include a data driving element, a gate driving element, a driving carrier DRB and a connecting element DRC. The data driving element may include a driving circuit DR1, and the gate driving element may include a driving circuit DR2. , a driving carrier DRB and a connecting element DRC. The driving circuit DR1 may be disposed on the driving carrier DRB, wherein the driving circuit DR1 may be an integrated circuit component, but the present disclosure is not limited thereto, and the driving carrier DRB may be a circuit board, such as a printed circuit board, but the present disclosure is not limited thereto. The driving carrier DRB may be joined to the joining area BR of the display panel 120 and connected to the data connection line SC1 through one or more connecting elements DRC. The connecting element DRA may be, for example, a flexible circuit board, but the present disclosure is not limited thereto. In this way, the driving circuit DR1 of the driving element DR may transmit corresponding signals to the pixel PX through the connecting element DRC and a plurality of data connection lines SC1. In addition, the driving circuit DR2 may be disposed on the display panel 120, and the driving circuit DR2 of the driving element DR may transmit a plurality of signals to the pixel PX through a plurality of scanning connection lines SC2.

[0098] In some embodiments, the driving circuit DR1 may include a data signal driving circuit for providing the data signal required by the pixel PX, and the driving circuit DR2 may include a scanning signal driving circuit for providing the scanning signal required by the pixel PX. In some embodiments, the driving circuit DR1 may be a packaged integrated circuit component, and the driving circuit DR2 may be composed of a plurality of transistors, a plurality of capacitors and other components fabricated on the display panel 120, but the present disclosure is not limited thereto. In some embodiments, the driving circuit DR2 has no independent packaging structure, but is integrated into the circuit layer of the pixel PX, but is not limited thereto. In other embodiments, the driving circuit DR2 (scanning signal driving circuit) may be implemented as a packaged integrated circuit component like the driving circuit DR1, or may be integrated into the packaged integrated circuit component of the driving circuit DR1.

[0099] In the present embodiment, the driving components DR are all located in the non-exposed area 100B of the transparent display device 100, which helps to improve the transmittance of the exposed area 100A, such as the transmittance of visible light, or improve the uniformity of the transmittance of the exposed area 100A. Therefore, during use, the transparent display device 100 can provide a good light transmission effect, and the transmittance of the exposed area 100A is uniform, so that the user can clearly see the environment behind the transparent display device 100. For example, when the rectangular range RR with the largest area is taken out from the range of the exposed area 100A, the center point RR1 of the rectangular range RR, the edge points RR2 and RR3 of the center point RR1 projected along the Z direction to the edge of the rectangular range RR, and the edge points RR4 and RR5 of the center point RR1 projected along the X direction to the edge of the rectangular range RR can be defined. The difference in the transmittance of the transparent display device 100 at the center point RR1, the edge point RR2, the edge point RR3, the edge point RR4 and the edge point RR5 can be within 30%. For example, |(transmittance T RRi -Penetration rate T RRj )│ / Penetration rate T RRi*100%≤30%, where i and j are any two of 1, 2, 3, 4, and 5. In this embodiment, the "transmittance" refers to the percentage of the light intensity of the penetrating light measured after the ambient light penetrates the transparent display device 100 divided by the light intensity measured when the ambient light does not penetrate the transparent display device 100. The aforementioned "light intensity" refers to the spectrum integral value of the light source (which may be, for example, display light or ambient light). In some embodiments, the light source may include visible light (for example, a wavelength between 380nm and 780nm) or ultraviolet light (for example, a wavelength less than 365nm), but is not limited thereto, meaning that when the light source is visible light, the light intensity is the spectrum integral value within the wavelength range of 380nm to 780nm. In other embodiments, when two area ranges of the same area are arbitrarily selected from the exposed area 100A of the transparent display device 100, the transmittances presented by the two area ranges are roughly close or the same. For example, when a region of a specified size is selected in the display area 120A of the exposed area 100A and a region of the same specified size is selected in the non-display area 120B of the exposed area 100A, the transmittances presented by the two regions may be substantially the same or differ by less than 30%.

[0100] According to some embodiments, when the transparent display device 100 is configured on the carrier 110, the relationship of the transmittances at the center point RR1, the edge point RR2, the edge point RR3, the edge point RR4, and the edge point RR5 may also conform to the above relationship: |(transmittance T RRi -Penetration rate T RRj )│ / Penetration rate T RRi *100%≤30%, where i and j are any two of 1, 2, 3, 4, and 5. In other words, regardless of whether the transparent display device 100 is disposed on the carrier 110, the transmittances corresponding to the center point RR1, the edge point RR2, the edge point RR3, the edge point RR4, and the edge point RR5 are substantially similar, and the effect of uniform transmittance can be achieved. In other words, the transmittances presented by the carrier 110 at various positions are substantially consistent. Figure 2 is a schematic diagram of a transparent display device in a first state according to an embodiment of the present disclosure, and Figure 3 for Figure 2 A schematic cross-sectional view of the device along line III-III. Figure 2 In the embodiment, the electronic device ED may include a transparent display device 100, a carrier board 110, and a frame 200. The transparent display device 100 may be installed in the frame 200. Figure 2 In the first state, the transparent display device 100 can be accommodated in the frame 200. At this time, the transparent display device 100 can be completely hidden by the frame 200. Figure 2 The components of the transparent display device 100 may be Figure 1The same or similar, no further description is given here. Figure 3 In the embodiment, the transparent display device 100 may include a display panel 120 and a driving element DR, wherein the display panel 120 may include a substrate 122, an exposed area component 124, and a non-exposed area component 126. In some embodiments, the exposed area component 124 may include Figure 1 The pixel PX and the related signal lines connected to the pixel PX are shown. In some embodiments, the exposed area component 124 may include a display component, and may also include a touch component, a sensing component, etc. The non-exposed area component 126 may include Figure 1 The data connection line SC1 and the scan connection line SC2 are shown. The driving element DR may include Figure 1 The driving circuit DR1, the driving circuit DR2, the driving carrier DRB and the connecting element DRC are shown. Figure 1 The driving circuit DR2 shown can also be disposed in the display panel 120 as a part of the exposed area component 124. In addition, the display panel 120 of the transparent display device 100 can also include a protective layer 128, which is disposed on the substrate 122 and covers the exposed area component 124 and the non-exposed area component 126 to reduce the probability of damage to the exposed area component 124 and the non-exposed area component 126.

[0101] The substrate 122 may be a multi-layer substrate, which is composed of a plurality of layer structures. In some embodiments, the layer structure constituting the substrate 122 may include an inflexible substrate, a flexible substrate, an insulating layer and a conductive layer or any combination thereof. The substrate 122 may be a hard substrate, a flexible substrate or a combination thereof, and the material of the substrate 122 may include, for example, glass, quartz, ceramic, sapphire, plastic, polycarbonate (PC), polyimide (PI), polypropylene (PP) or polyethylene terephthalate (PET), other suitable materials or a combination of the aforementioned materials, but is not limited thereto. In some embodiments, at least one of the layer structures of the substrate 122 may have a plurality of slits or holes, and the slits or holes are disposed in the exposed area 100A of the transparent display device 100. In other embodiments, at least one of the layer structures of the substrate 122 may have slits or holes in the non-exposed area 100B. Providing slits or holes in the substrate 122 helps to improve the flexibility, transparency and / or stretchability of the substrate 122, so that the display panel 120 can conform to surfaces with different curvature structures or conform to surfaces with irregular shapes. In some embodiments, providing slits or holes in the substrate 122 can also help to improve the transmittance of the display panel 120. In addition, the protective layer 128 can be made of different materials in different areas. For example, the protective layer 128 can be a light-transmitting material in the exposed area 100A, and can be a light-proof / light-shielding material in the non-exposed area 100B. For example, the transmittance of the light-proof / light-shielding material is less than the transmittance of the light-transmitting material.

[0102] Depend on Figure 3 It can be seen that the frame 200 can accommodate the transparent display device 100 and the frame 200 has an opening 202. In some embodiments, a driving mechanism (not shown) may be provided in the frame 200, and the transparent display device 100 may be installed on the driving mechanism, so that the driving mechanism can push the transparent display device 100 to move in the direction Z, so that the transparent display device 100 can protrude from the opening 202 of the frame 200 to expose the exposed area 100A or the transparent display device 100 is completely hidden in the frame 200. In some embodiments, the design of installing the transparent display device 100 in the frame 200 can be applied to windows, such as car windows, but is not limited thereto. In other embodiments, the design of installing the transparent display device 100 in the frame 200 can be applied to display windows or similar products.

[0103] Figure 4 is a schematic diagram of a transparent display device in a second state according to an embodiment of the present disclosure, and Figure 5 for Figure 4 Schematic cross-sectional view of the device along line VV. Figure 4 The components presented are Figure 2 Same and Figure 5 The components presented are Figure 3 Same, but Figure 4 and Figure 5 The transparent display device 100 is shown in the second state. In the second state, the transparent display device 100 can be moved to expose the frame 200. In some embodiments, the transparent display device 100 can be moved by a driving mechanism disposed in the frame 200 to be in the second state. Figure 4 and Figure 5 status. Figure 4 and Figure 5 In the state of, the area of ​​the transparent display device 100 not shielded by the frame 200 is Figure 1 The exposed area 100A is the area of ​​the transparent display device 100 shielded by the frame 200. Figure 1 The non-exposed area 100B. Figure 4 and Figure 5 The state presented is, for example, a state where the driving mechanism is at the limit of movement. That is, the driving mechanism is no longer able to move the transparent display device 100 from Figure 4 and Figure 5 The exposed area 100A is, for example, located at Figure 4 and Figure 5 The boundary of the exposed area 100A can be defined as Figure 4 and Figure 5 In the state, it is defined along the boundary of the frame 200.

[0104] In addition, in other states, the relative position of the transparent display device 100 and the frame 200 may be between Figure 2 and Figure 4 At this time, the exposed area 100A may be partially hidden by the frame 200, while the non-exposed area 100B is hidden by the frame 200 in any state. Therefore, during the use of the user, the non-exposed area 200 will not be seen by the user, while the exposed area 100 can be partially or completely seen by the user according to the adjustment of the use state. In some embodiments, the transparent display device 100 can be applied to a car window, wherein Figure 2 and Figure 3 The first state is that the window is fully opened, and Figure 4 and Figure 5 The second state is a state where the window is completely closed. According to the above description, the exposed area 100A has a uniform transmittance, so when the transparent display device 100 is applied to a window, the window can have a uniform transmittance and present a desired visual effect.

Figure 6 In the amplification area E1, three pixels PX may be provided, which are pixel PXR, pixel PXG and pixel PXB. In addition, the amplification area E1 also includes a plurality of first signal lines SL1 and a plurality of second signal lines SL2. Pixel PXR, pixel PXG and pixel PXB are each light-emitting pixels, which can emit light for displaying images. In some embodiments, pixel PXR, pixel PXG and pixel PXB can emit light of different colors, such as red light, green light, blue light, etc., but not limited to this. Each first signal line SL1 extends, for example, along the Z direction, and each second signal line SL2 extends, for example, along the X direction. The pixel PXR, pixel PXG and pixel PXB can share one of the second signal lines SL2, and correspond to different first signal lines SL1 respectively. Specifically, Figure 6 The layout presents a first signal line SL1 , a pixel PXR, a first signal line SL1 , a pixel PXG, a first signal line SL1 , and a pixel PX arranged in sequence along the X direction, but the present invention is not limited thereto.

[0106] In this embodiment, the enlarged area E1 also includes a pixel transparent area TPX, wherein the pixel transparent area TPX refers to a region without signal lines and pixels PX. That is, the user can see through the transparent display device 100 in the pixel transparent area TPX. Figure 6 In the embodiment, the pixels PX are arranged in a centralized manner, so the pixel transparent area TPX is located on the same side of the pixels PXR, the pixels PXG and the pixels PXB, but the present invention is not limited thereto. In some embodiments, a transmittance adjustment layer (not shown) may be further provided in the pixel transparent area TPX or in an area corresponding to the pixel transparent area TPX (e.g., an area overlapping the pixel transparent area TPX when viewed along the direction Y). The transmittance adjustment layer may be provided at Figure 3 The transmittance adjusting layer is between the substrate 122 and the carrier 110 in the cross-sectional structure. The transmittance of the transmittance adjusting layer can be controlled by an electrical signal, and examples of its material may include dye liquid crystal (Dichroic dye liquid crystal, DDLC), polymer dispersed liquid crystal (Polymer dispersed liquid crystal, PDLC), polymer network liquid crystal (Polymer network liquid crystal, PNLC), cholesterol liquid crystal (Cholesteric liquid crystal, CLC), electrochromic material (Electrochromic, EC), suspended particle device (Suspended Particle Device, SPD) or a combination thereof.

[0107] The transmittance adjustment layer can improve the visual contrast of the transparent display device 100. For example, in an environment where the light intensity of the ambient light is high, the transmittance of the transmittance adjustment layer can be reduced to shield the ambient light and make the displayed image on the transparent display device 100 easier to identify. In addition, in some embodiments, when the transparent display device 100 is applied to products such as car windows or windows, when the light intensity of the ambient light is too high, the transmittance of the transmittance adjustment layer can be reduced to shield the external ambient light and improve the visual comfort of the passengers. Alternatively, reducing the transmittance of the transmittance adjustment layer helps to improve the privacy of the passengers, but the present disclosure is not limited to this.

Figure 1 In the layout, each scanning connection line SC2 can be used to electrically connect one of the second signal lines SL2 to the driving circuit DR2. In addition, each scanning connection line SC2 can be divided into a connection line exposed segment SC2A and a connection line hidden segment SC2B, wherein the connection line exposed segment SC2A refers to the segment of the scanning connection line SC2 located in the exposed area 100A, and the connection line hidden segment SC2B refers to the segment of the scanning connection line SC2 located in the non-exposed area 100B. The connection line exposed segments SC2A of the scanning connection lines SC2 are presented in the enlarged area E2. The layout of the connection line exposed segments SC2A in the enlarged area E2 is, for example, grouped. For example, several connection line exposed segments SC2A can be centrally arranged to form a connection line group GSC, and adjacent connection line groups GSC are separated by a spacing SSC, wherein there are no connection lines in the spacing SSC. Therefore, the spacing SSC can define a connection line transparent area TSC.

[0109] In some embodiments, Figure 6 The amplified area E1 and Figure 7 The enlarged area E2 can have the same area and the pixel transparent area TPX in the enlarged area E1 and the connection line transparent area TSC in the enlarged area E2 can have a similar or the same area. In this way, the transmittance of the enlarged area E1 and the transmittance of the enlarged area E2 can be substantially the same, thereby achieving the exposed area 100A (such as Figure 1 ) has a design with uniform penetration.

Fig. 9 In the embodiment, the exposed connecting wire segments SC2A are arranged in the enlarged area E2 in a substantially evenly spaced manner, so that the transparent connecting wire area TSC is divided into a plurality of areas by the exposed connecting wire segments SC2A. In general, when the enlarged area E1 and the enlarged area E2 have similar areas, the overall area of ​​the transparent connecting wire area TSC can be substantially similar to or even equal to the overall area of ​​the transparent pixel area TPX, so that the exposed area 100A (shown in FIG. Figure 1 ) has uniform penetration as a whole.

In some embodiments, at least one insulating layer in the insulating layer stack INX and the insulating layer constituting the substrate 122 may have the same material. The protective layer PR may be made of different materials in different areas. For example, the protective layer PR may be made of a transparent material in the exposed area 100A and may be made of an opaque / light-shielding material in the non-exposed area 100B. For example, the transmittance of the opaque / light-shielding material is lower than that of the transparent material.
