Description

Technical Field

[0001] This disclosure relates to an electronic device, and more particularly to an electronic device having a transmissive area and a light-emitting area. Background Technology

[0002] With technological advancements, the applications of displays have become increasingly diverse. Because transparent displays possess a certain degree of transmittance, users can view the displayed content while simultaneously seeing the scene behind the display. In some cases, transparent displays with dual-sided display capabilities have also been proposed, further expanding their application range.

[0003] Generally, a transparent display with dual-sided display capability combines two transparent displays to present a front image and a rear image respectively. However, this approach requires more display components (such as light-emitting diodes) and circuitry (such as driving circuitry), thus requiring more space to house these components and circuitry. This can lead to problems such as the aperture ratio of the transparent display in the transmission area being affected.

[0004] Therefore, researchers in this field continue to improve transparent displays to meet the needs of users now and in the future. Summary of the Invention

[0005] The embodiments of this disclosure provide an electronic device that, by designing a light-emitting structure to overlap with a dimming structure, displays a first image viewed from a first side during a first period of frame time and a second image viewed from a second side during a second period of frame time. This helps to reduce the number of components and circuits used to achieve the dual-sided display function, so that the electronic device can have the dual-sided display function while also reducing the impact on the aperture ratio of the penetration area.

[0006] Embodiments of this disclosure provide an electronic device having a first side and a second side opposite to the first side, and including a dimming structure and a light-emitting structure overlapping the dimming structure. During frame time, the light-emitting structure displays a first image during a first period of frame time, and displays a second image during a second period of frame time, the first image being viewed from the first side and the second image being viewed from the second side.

[0007] Based on the above, in an electronic device according to an embodiment of the present disclosure, the light-emitting structure displays a first image viewed from a first side during a first period of frame time, and displays a second image viewed from a second side during a second period of frame time. This helps to reduce the number of components and circuits used to implement the dual-sided display function, so that the electronic device can have the dual-sided display function while reducing the impact on the aperture ratio of its penetration area.

Figure 2A This is a cross-sectional schematic diagram of the first embodiment of the present disclosure during the first period of the frame time.

[0030] Please refer to Figure 1The electronic device 10 has a first side S1 and a second side S2 opposite to the first side S1, and includes a dimming structure LAS1 (or dimming structure LAS2) and a light-emitting structure LES1 overlapping the dimming structure LAS1 or LAS2. In this embodiment, during a frame time, the light-emitting structure LES1 displays a first image viewed by the first side S1 (e.g., an image observed by observer Obs1) during a first period of the frame time, and displays a second image viewed by the second side S2 (e.g., an image observed by observer Obs2) during a second period of the frame time. This helps to reduce the number of components and circuits used to implement the double-sided display function, so that the electronic device 10 can have the double-sided display function while also reducing the impact on the aperture ratio of the transmission area TR1. In this embodiment, the dimming structure LAS1 or LAS2 can be configured to control the passage or block light. In this disclosure, "frame time" refers to the time it takes to display one frame. For example, when the refresh rate of an electronic device is 60Hz, one frame time is 1 / 60 of a second. "Overlap" in this disclosure refers to, for example, the overlap of two objects in the viewing direction, or the overlap of dimming structures (LAS1 or LAS2) in the direction toward the light-emitting structure LES1, or the overlap in the normal direction of the surface of the substrate on which the light-emitting unit LES1 is provided.

[0031] In this embodiment, the electronic device 10 may include a dimming structure LAS1 and another dimming structure LAS2, wherein the dimming structure LAS1 is located near the first side S1, the other dimming structure LAS2 is located near the second side S2, and the light-emitting structure LES1 is located between the dimming structure LAS1 and the other dimming structure LAS2. In this embodiment, the dimming structure LAS1 may be disposed between the substrate SUB1 and the light-emitting structure LES1, while the other dimming structure LAS2 may be disposed between the substrate SUB2 and the light-emitting structure LES1. The substrate SUB1 and the substrate SUB2 may each comprise any suitable transparent substrate material, such as a glass substrate or other flexible substrate, but this disclosure is not limited thereto. The dimming structure LAS1 and the other dimming structure LAS2 may each comprise a dimming structure such as an electroluminescent dimming structure, an electrowetting dimming structure, or a dye liquid crystal dimming structure.

[0032] In this embodiment, the light-emitting structure LES1 may include a substrate SUB3, a plurality of light-emitting units LEU1 disposed on the substrate SUB3, and a dielectric layer DL1 disposed on the substrate SUB3 and covering the light-emitting units LEU1. The substrate SUB3 may include any suitable transparent substrate material, such as a glass substrate or other flexible substrate, but this disclosure is not limited thereto. The light-emitting units LEU1 may include light-emitting elements. Light-emitting elements may include light-emitting diodes (LEDs), quantum dots (QDs), fluorescence, phosphorescence, other suitable materials, or combinations thereof. Light-emitting diodes may include, for example, organic light-emitting diodes (OLEDs), micro-LEDs, mini-LEDs, or quantum dot light-emitting diodes (QLEDs, QDLEDs), but are not limited thereto. The dielectric layer DL1 may contain any suitable dielectric material. According to some embodiments, the dielectric layer DL1 may contain inorganic materials, organic materials, or combinations thereof, but is not limited thereto. According to some embodiments, the inorganic material may include silicon nitride, silicon oxide, silicon oxynitride, aluminum oxide, other suitable materials, or combinations thereof, but is not limited thereto.

[0033] In this embodiment, the electronic device 10 may include a light-emitting area ER1 in which light-emitting units LEU1 are disposed, and a transmission area TR1 between multiple light-emitting units LEU1. In this embodiment, the light generated by the light-emitting units LEU1 can be incident on observers Obs1 and Obs2 through the first side S1 and the second side S2, respectively. In this embodiment, the transmission area TR1 may refer to the area of ​​the entire electronic device 10 that allows ambient light to pass through, while areas in which light-blocking films (e.g., light-shielding layers), traces (e.g., signal lines), and components (e.g., active components) are formed are not included in the transmission area defined in this embodiment.

[0034] In the first embodiment, please refer to Figure 1 and Figures 2A to 2C The dimming structure LAS1 may include multiple first dimming units LAU1, each of which includes a first light-emitting area ER1 and a first light-transmitting area TR1. Another dimming structure LAS2 may include multiple second dimming units LAU2, each of which includes a second light-emitting area ER2 and a second light-transmitting area TR2. The multiple first dimming units LAU1 and the multiple second dimming units LAU2 can be respectively configured to correspond to multiple light-emitting units LAU1, thus achieving the desired display effect by individually controlling the first dimming units LAU1 and the second dimming units LAU2. In this embodiment, as... Figures 2A to 2CAs shown, the first light-emitting region ER1 can overlap with the second light-emitting region ER2, and the first penetrating region TR1 can overlap with the second penetrating region TR2.

[0035] In the first embodiment, please refer to Figures 2A to 2C The dimming structure LAS1 may include a first electrowetting dimming structure EWS1, and the other dimming structure LAS2 may include a second electrowetting dimming structure EWS2. The first electrowetting dimming structure EWS1 may include a first non-polar solution (e.g., the first non-polar solution NPS1v, NPS1nv of electronic devices 20a, 20b, 20c at different periods of the frame time), and the second electrowetting dimming structure EWS2 may include a second non-polar solution (e.g., the second non-polar solution NPS2v, NPS2nv of electronic devices 20a, 20b, 20c at different periods of the frame time). The first non-polar solution NPS1v, NPS1nv and the second non-polar solution NPS2v, NPS2nv may each include a non-polar solution such as ink, but this disclosure is not limited thereto.

[0036] In a first embodiment, the first electrowetting dimming structure EWS1 may include a first electrode pattern EL1a disposed on a substrate SUB1, a first hydrophobic layer HBL1 disposed on the substrate SUB1 and covering the first electrode pattern EL1a, a first hydrophilic barrier HLD1 disposed on the first hydrophobic layer HBL1, a first polar solution PS1 and first non-polar solutions NPS1v and NPS1nv, and a first electrode layer EL1b disposed above the first hydrophobic layer HBL1, wherein the first polar solution PS1 and the first non-polar solutions NPS1v and NPS1nv are sandwiched between the first hydrophobic layer HBL1 and the first electrode layer EL1b, and the first non-polar solutions NPS1v and NPS1nv are disposed in the area defined by the first hydrophilic barrier HLD1. In some embodiments, the first hydrophilic barrier HLD1 may be used to define the light-shielding position of the first dimming unit LAU1.

[0037] In a first embodiment, the second electrowetting dimming structure EWS2 may include a second electrode pattern EL2a disposed on a substrate SUB2, a second hydrophobic layer HBL2 disposed on the substrate SUB2 and covering the second electrode pattern EL2a, a second hydrophilic barrier HLD2 disposed on the second hydrophobic layer HBL2, a second polar solution PS2 and second non-polar solutions NPS2v and NPS2nv, and a second electrode layer EL2b disposed above the second hydrophobic layer HBL2, wherein the second polar solution PS2 and the second non-polar solutions NPS2v and NPS2nv are sandwiched between the second hydrophobic layer HBL2 and the second electrode layer EL2b, and the second non-polar solutions NPS2v and NPS2nv are disposed in the area defined by the second hydrophilic barrier HLD2. In some embodiments, the second hydrophilic barrier HLD2 may be used to define the light-shielding position of the second dimming unit LAU2.

[0038] The first electrode pattern EL1a, the first electrode layer EL1b, the second electrode pattern EL2a, and the second electrode layer EL2b may each include any suitable transparent electrode material, such as indium tin oxide (ITO), indium zinc oxide (IZO), or zinc oxide (ZnO), but this disclosure is not limited thereto.

[0039] The first hydrophobic layer HBL1 and the second hydrophobic layer HBL2 may each comprise any suitable hydrophobic material. For example, the first hydrophobic layer HBL1 and the second hydrophobic layer HBL2 may be fluorinated polymer layers, cobalt-like carbon layers, or self-polymerizing monolayers, but this disclosure is not limited thereto.

[0040] The first hydrophilic barrier HLD1 and the second hydrophilic barrier HLD2 may each comprise any suitable hydrophilic material, such as epoxy resin or acrylic resin, but this disclosure is not limited thereto.

[0041] The first polar solution PS1 and the second polar solution PS2 may each comprise any suitable polar solution, such as water or an aqueous solution containing electrolytes, but this disclosure is not limited thereto. The first nonpolar solutions NPS1v and NPS1nv and the second nonpolar solutions NPS2v and NPS2nv may each comprise any suitable nonpolar solution, such as ink or other nonpolar solutions, but this disclosure is not limited thereto.

[0042] Figure 2A This represents the state of electronic device 20a during the first period of the frame time. For example... Figure 2AAs shown, a bias voltage is provided between the first electrode pattern EL1a and the first electrode layer EL1b, causing electrowetting of the first hydrophobic layer HBL1 in the region overlapping the first electrode pattern EL1a and the first electrode layer EL1b (i.e., the region where the electric field is distributed). This results in the first nonpolar solution NPS1v being pushed by the first polar solution PS1 into the region of the first hydrophobic layer HBL1 where there is no electric field distribution (e.g., pushed into the region that does not overlap with the first electrode pattern EL1a). In this way, the first nonpolar solution NPS1v can overlap with the first light-emitting region ER1 but not with the first transmission region TR1 during the first period, and the first nonpolar solution NPS1v does not overlap with the light-emitting unit LEU1. On the other hand, as Figure 2A As shown, no bias voltage is provided between the second electrode pattern EL2a and the second electrode layer EL2b, so that the second hydrophobic layer HBL2 does not exhibit electrowetting due to the electric field distribution in the second light-emitting region ER2 and the second light-transmitting region TR2. Therefore, the second non-polar solution NPS2nv is laid flat on the second hydrophobic layer HBL2 to overlap with the second light-emitting region ER2 and the second light-transmitting region TR2. That is, during the first period of the frame time in the electronic device 20a, the first non-polar solution NPS1v overlaps with the first light-emitting region ER1 but not with the first light-transmitting region TR1, and the first non-polar solution NPS1v does not overlap with the light-emitting unit LEU1, while the second non-polar solution NPS2nv overlaps with the second light-emitting region ER2 and the second light-transmitting region TR2. In this way, the electronic device 20a can display the first image viewed from the first side S1 during the first period, while the ambient light from the second side S2 can be blocked by the second non-polar solution NPS2nv, thereby helping to reduce the interference of the first image from the ambient light from the second side S2.

[0043] In this embodiment, the electronic device 20a may further include a circuit layer CL1 electrically connected to the light-emitting unit LEU1. In this embodiment, the circuit layer CL1 may be configured not to overlap with the light-emitting unit LEU1, thereby reducing the influence of the lines in the circuit layer CL1 on the light emitted by the light-emitting unit LEU1 toward the first side S1 and / or the second side S2. In this embodiment, the first non-polar solution NPS1v may overlap with the circuit layer CL1 but not with the light-emitting unit LEU1 during the first period.

[0044] Figure 2B This refers to the state of electronic device 20b during the second period of the frame time. For example... Figure 2BAs shown, a bias voltage is provided between the second electrode pattern EL2a and the second electrode layer EL2b, causing electrowetting of the second hydrophobic layer HBL2 in the region overlapping the second electrode pattern EL2a and the second electrode layer EL2b (i.e., the region where the electric field is distributed). This results in the second nonpolar solution NPS2v being pushed by the second polar solution PS2 into the region of the second hydrophobic layer HBL2 where there is no electric field distribution (e.g., pushed into the region that does not overlap with the second electrode pattern EL2a). In this way, the second nonpolar solution NPS2v can overlap with the second light-emitting region ER2 but not with the second penetration region TR2 during the second period, and the second nonpolar solution NPS2v does not overlap with the light-emitting unit LEU1. On the other hand, as Figure 2B As shown, no bias voltage is provided between the first electrode pattern EL1a and the first electrode layer EL1b, so that the first hydrophobic layer HBL1 does not exhibit electrowetting due to the electric field distribution in the first light-emitting region ER1 and the first light-transmitting region TR1. Therefore, the first non-polar solution NPS1nv is laid flat on the first hydrophobic layer HBL1 to overlap with the first light-emitting region ER1 and the first light-transmitting region TR1. That is, when the electronic device 20b is in the second period of the frame time, the second non-polar solution NPS2v overlaps with the second light-emitting region ER2 but does not overlap with the second light-transmitting region TR2, and the second non-polar solution NPS2v does not overlap with the light-emitting unit LEU1, while the first non-polar solution NPS1nv overlaps with the first light-emitting region ER1 and the first light-transmitting region TR1. In this way, the electronic device 20b can display the second image viewed from the second side S2 during the second period, while the ambient light from the first side S1 can be blocked by the first non-polar solution NPS1nv, thereby helping to reduce the interference of the second image from the ambient light from the first side S1.

[0045] Figure 2C This represents the state of electronic device 20c during the third period of the frame time. For example... Figure 2C As shown, a bias voltage is provided between the first electrode pattern EL1a and the first electrode layer EL1b, causing electrowetting of the first hydrophobic layer HBL1 in the region overlapping the first electrode pattern EL1a and the first electrode layer EL1b (i.e., the region where the electric field is distributed). This results in the first nonpolar solution NPS1v being pushed by the first polar solution PS1 into the region of the first hydrophobic layer HBL1 where there is no electric field distribution (e.g., pushed into the region that does not overlap with the first electrode pattern EL1a). In this way, the first nonpolar solution NPS1v can overlap with the first light-emitting region ER1 but not with the first transmission region TR1 during the third period. On the other hand, as... Figure 2CAs shown, a bias voltage is provided between the second electrode pattern EL2a and the second electrode layer EL2b, causing electrowetting of the second hydrophobic layer HBL2 in the region overlapping the second electrode pattern EL2a and the second electrode layer EL2b (i.e., the region where the electric field is distributed). This causes the second nonpolar solution NPS2v to be pushed by the second polar solution PS2 into the region of the second hydrophobic layer HBL2 where there is no electric field distribution (e.g., pushed into the region that does not overlap with the second electrode pattern EL2a). In this way, the second nonpolar solution NPS2v can overlap with the second light-emitting region ER2 but not with the second transmission region TR2 during the third period. That is, when the electronic device 20c is in the third period of the frame time, the electronic device 20c can be in the state of a transparent display with dual-sided display function, which can display a first image and a second image on the first side S1 and the second side S2. Alternatively, the electronic device 20c can display an image presented by ambient light originating from the second side S2 on the first side S1, and display an image presented by ambient light originating from the first side S1 on the second side S2, i.e., the state of the window.

[0046] Figure 3A This is a cross-sectional schematic diagram of the second embodiment of the present disclosure during the first period of the frame time. Figure 3B This is a cross-sectional schematic diagram of the second embodiment of the present disclosure during the second period of the frame time. Figure 3A The electronic device 30a of the second embodiment shown is Figure 2A The electronic device 20a of the first embodiment shown is similar, except that the dimming structure LAS3 of the electronic device 30a is different from the dimming structure LAS1 of the electronic device 20a, and another dimming structure LAS2 is not included in the electronic device 30a. Other identical or similar elements are represented by the same or similar element symbols, and will not be described again here.

[0047] In the second embodiment, please refer to Figure 1 and Figure 3A and Figure 3BThe dimming structure LAS3 may include multiple dimming units LAU3 corresponding to multiple light-emitting units LEU1, wherein each dimming unit LAU3 includes a light-emitting region ER3, a transmission region TR3, and a reflection region RR1. In this embodiment, the dimming structure LAS3 may include a reflective layer RL1 disposed in the reflection region RR1 and a dielectric layer DL2 disposed on the substrate SUB1 and covering the reflective layer RL1. The reflective layer RL1 may include any material suitable for reflecting light, such as a metallic material such as aluminum or silver, or a metal oxide such as titanium oxide, but this disclosure is not limited thereto. The dielectric layer DL2 may contain any suitable dielectric material. According to some embodiments, the dielectric layer DL2 may contain inorganic materials, organic materials, or combinations thereof, but is not limited thereto. According to some embodiments, the inorganic material may contain silicon nitride, silicon oxide, silicon oxynitride, aluminum oxide, other suitable materials, or combinations thereof, but is not limited thereto.

[0048] In the second embodiment, please refer to Figure 3A and Figure 3B The dimming structure LAS3 may include an electrowetting dimming structure EWS3, wherein the electrowetting dimming structure EWS3 may include a non-polar solution NPS3v. The non-polar solution NPS3v may include non-polar solutions such as inks, but this disclosure is not limited thereto.

[0049] In a second embodiment, the electrowetting dimming structure EWS3 may include an electrode pattern EL3a disposed on a substrate SUB1, a hydrophobic layer HBL1 disposed on the substrate SUB1 and covering the electrode pattern EL3a, a hydrophilic barrier HLD1 disposed on the hydrophobic layer HBL1, a polar solution PS1 and a non-polar solution NPS3v disposed on the hydrophobic layer HBL1, and an electrode layer EL3b disposed above the hydrophobic layer HBL1, wherein the polar solution PS1 and the non-polar solution NPS3v are sandwiched between the hydrophobic layer HBL1 and the electrode layer EL3b, and the non-polar solution NPS3v is disposed in the area defined by the hydrophilic barrier HLD1. In some embodiments, the hydrophilic barrier HLD1 may be used to define the light-shielding position of the dimming unit LAU3. In this embodiment, the electrode pattern EL3a may include a first portion EL3a1, a second portion EL3a2, and a third portion EL3a3 that are horizontally separated from each other.

[0050] Figure 3A This represents the state of electronic device 30a during the first period of the frame time. For example... Figure 3AAs shown, a bias voltage is provided between the second portion EL3a2 of the electrode pattern EL3a and the electrode layer EL3b, but not between the first portion EL3a1 of the electrode pattern EL3a and the electrode layer EL3b, or between the third portion EL3a3 of the electrode pattern EL3a and the electrode layer EL3b. This causes electrowetting of the hydrophobic layer HBL1 in the area overlapping the second portion EL3a2 of the electrode pattern EL3a. This results in the nonpolar solution NPS3v being pushed by the polar solution PS1 to both sides of the second portion EL3a2 of the electrode pattern EL3a, including the first portion MPS3v1 overlapping the first portion EL3a1 of the electrode pattern EL3a and the second portion MPS3v2 overlapping the third portion EL3a3 of the electrode pattern EL3a. In other words, the nonpolar solution NPS3v can overlap the reflective region RR1 and the transmissive region TR3 during the first period, but not the luminescent region ER3. In this way, the electronic device 30a can display a first image viewed from the first side S1 during the first period.

[0051] In this embodiment, the electronic device 30a may further include a circuit layer CL2 electrically connected to the light-emitting unit LEU1. In this embodiment, the circuit layer CL2 may be configured to overlap with the light-emitting unit LEU1.

[0052] Figure 3B This represents the state of electronic device 30b during the second period of the frame time. For example... Figure 3B As shown, a bias voltage is provided between the third portion EL3a3 of the electrode pattern EL3a and the electrode layer EL3b, but not between the first portion EL3a1 of the electrode pattern EL3a and the electrode layer EL3b, or between the second portion EL3a2 of the electrode pattern EL3a and the electrode layer EL3b. This causes electrowetting of the hydrophobic layer HBL1 in the region overlapping the third portion EL3a3 of the electrode pattern EL3a, resulting in the nonpolar solution NPS3v being pushed by the polar solution PS1 to the region not overlapping with the third portion EL3a3 of the electrode pattern EL3a (e.g., the region overlapping with the first portion EL3a1 and the second portion EL3a2 of the electrode pattern EL3a). In other words, the nonpolar solution NPS3v can overlap the transmission region TR3 and the light-emitting region ER3 during the second period, but not the reflection region RR1. In this way, the electronic device 30b can display the second image viewed from the second side S2 through the reflection layer RL1 in the reflection region RR1 during the second period. In other embodiments, the frame time may also include a third period in which a bias may be provided between the first portion EL3a1 of the electrode pattern EL3a and the electrode layer EL3b, but not between the third portion EL3a3 of the electrode pattern EL3a and the electrode layer EL3b, or between the second portion EL3a2 of the electrode pattern EL3a and the electrode layer EL3b, during which the electronic device is in a transparent state, but this disclosure is not limited thereto.

[0053] Figure 4A This is a cross-sectional schematic diagram of a period of time according to a third embodiment of the present disclosure. Figure 4B This is a cross-sectional schematic diagram of the third embodiment of the present disclosure at another period of time in the frame. Figure 4A The electronic device 40a of the third embodiment shown is Figure 2A The electronic device 20a of the first embodiment shown is similar, except that the dimming structure LAS4 of the electronic device 40a is different from the dimming structure LAS1 of the electronic device 20a, and another dimming structure LAS2 is not included in the electronic device 40a. Other identical or similar elements are represented by the same or similar element symbols, and will not be described again here.

[0054] In the third embodiment, please refer to Figure 1 and Figure 4A and Figure 4B The dimming structure LAS4 may include multiple dimming units LAU4 corresponding to multiple light-emitting units LEU1, wherein each dimming unit LAU4 includes a light-emitting area ER4 and a transmission area TR4. In this embodiment, the dimming structure LAS4 may include an electrowetting dimming structure EWS4, wherein the electrowetting dimming structure EWS4 may include a non-polar solution NPS4v. The non-polar solution NPS4v may include a non-polar solution such as ink, but this disclosure is not limited thereto.

[0055] In the third embodiment, the electrowetting dimming structure EWS4 may include an electrode pattern EL4a disposed on a substrate SUB1, a hydrophobic layer HBL1 disposed on the substrate SUB1 and covering the electrode pattern EL4a, a hydrophilic barrier HLD1 disposed on the hydrophobic layer HBL1, a polar solution PS1 and a non-polar solution NPS4v disposed on the hydrophobic layer HBL1, and an electrode layer EL4b disposed above the hydrophobic layer HBL1, wherein the polar solution PS1 and the non-polar solution NPS4v are sandwiched between the hydrophobic layer HBL1 and the electrode layer EL4b, and the non-polar solution NPS4v is disposed in the area defined by the hydrophilic barrier HLD1. In this embodiment, the electrode pattern EL4a may include a first portion EL4a1 and a second portion EL4a2 that are horizontally separated from each other.

[0056] Figure 4A This represents the state of electronic device 40a during a specific period within the frame time. For example... Figure 4AAs shown, a bias voltage is provided between the second portion EL4a2 of the electrode pattern EL4a and the electrode layer EL4b, but not between the first portion EL4a1 of the electrode pattern EL4a and the electrode layer EL4b. This causes electrowetting of the hydrophobic layer HBL1 in the region overlapping the second portion EL4a2 of the electrode pattern EL4a. This results in the nonpolar solution NPS4v being pushed by the polar solution PS1 into the region that does not overlap with the second portion EL4a2 of the electrode pattern EL4a (e.g., the region that overlaps with the first portion EL4a1 of the electrode pattern EL4a). In other words, the nonpolar solution NPS4v can overlap the light-emitting region ER4 but not the light-transmitting region TR4 during this period. In this way, the electronic device 40a can display an image presented by ambient light originating from the second side S2 on the first side S1, and display an image presented by ambient light originating from the first side S1, i.e., the state of the window, on the second side S2.

[0057] Figure 4B This represents the state of electronic device 40b during another period of the frame time. For example... Figure 4B As shown, a bias voltage is applied between the first portion EL4a1 of the electrode pattern EL4a and the electrode layer EL4b, but not between the second portion EL4a2 of the electrode pattern EL4a and the electrode layer EL4b. This causes electrowetting of the hydrophobic layer HBL1 in the area overlapping the first portion EL4a1 of the electrode pattern EL4a. This results in the nonpolar solution NPS4v being pushed by the polar solution PS1 into the area that does not overlap with the first portion EL4a1 of the electrode pattern EL4a (e.g., the area overlapping with the second portion EL4a2 of the electrode pattern EL4a). In other words, the nonpolar solution NPS4v can overlap the transmission region TR4 but not the light-emitting region ER4 during the other period. In this way, the electronic device 40b can display a first image viewed from the first side S1 during the other period, while ambient light from the second side S2 can be blocked by the nonpolar solution NPS4v, thereby helping to reduce interference of the first image from ambient light from the second side S2.

[0058] Figure 5 This is a flowchart of the manufacture of an electronic device according to an embodiment of the present disclosure. Figure 6 This is a flowchart of the manufacture of an electronic device according to another embodiment of the present disclosure. Figure 1 The electronic device 10 shown can, for example, be transmitted via... Figure 5 The process shown is for manufacturing, but this disclosure is not limited thereto.

[0059] Please refer to Figure 5Manufacturing an electronic device may include the following steps. First, a light-emitting structure LES1 is provided. Next, a dimming structure LAS1 is sandwiched between the light-emitting structure LES1 and a substrate SUB1. In some embodiments, the dimming structure LAS1 may be formed first on one side of the light-emitting structure LES1, and then the substrate SUB1 may be covered on the dimming structure LAS1, but this disclosure is not limited thereto. In other embodiments, the dimming structure LAS1 may be formed first on the substrate SUB1, and then the dimming structure LAS1 formed on the substrate SUB1 may be bonded to one side of the light-emitting structure LES1. Subsequently, a dimming structure LAS2 formed on the substrate SUB2 may be bonded to the other side of the light-emitting structure LES1.

[0060] In other embodiments, such as Figure 6 As shown, in an embodiment where the light-emitting unit LEU1 is formed on, for example, a flexible substrate SUB3', a method for manufacturing an electronic device may include the following steps. First, a light-emitting structure LES1' is provided on a carrier substrate CSUB. Next, a dimming structure LAS1 is sandwiched between the light-emitting structure LES1 and the substrate SUB1 using the method described above. Then, the carrier substrate CSUB is removed. Afterwards, as... Figure 5 As shown, the dimming structure LAS2 formed on the substrate SUB2 is bonded to the other side of the light-emitting structure LES1'.

[0061] In summary, in the electronic device of the embodiments of this disclosure, the light-emitting structure displays a first image viewed from a first side during a first period of the frame time, and displays a second image viewed from a second side during a second period of the frame time. This helps to reduce the number of components and circuits used to implement the dual-sided display function, enabling the electronic device to have a dual-sided display function while reducing the impact on the aperture ratio of its penetration area.
