Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a display component and an electronic device. Background Technology

[0002] With the development of terminal technology, wearable devices, such as smart bracelets and watches, are becoming increasingly diverse. Simultaneously, people are becoming more reliant on terminals, with most carrying various devices to handle work and daily life tasks. To meet users' demands for large screens and portability, terminal designs with foldable display modules have emerged. To ensure a stable connection between the stacked functional layers in a foldable display module, structural adhesive layers are introduced between at least some adjacent functional layers. However, while existing structural adhesive layers in foldable display modules offer good adhesion, they create creases during bending. Prolonged closure leads to significantly deepened creases that are difficult to remove, affecting aesthetics and reducing user experience. Summary of the Invention

[0003] One embodiment of this application provides a display component, including: a display panel having a bent portion and a non-bent portion rotatable around the bent portion; an electrochromic layer stacked on the display panel, the electrochromic layer at least covering the bent portion; when the display component is in a screen-on state or a screen-off state, the electrochromic layer is configured to be in a transparent state to allow light emitted from the display panel to pass through; when the display component is in a screen-off state, the electrochromic layer is configured to be in a reflective state to reflect light directed toward the display panel.

[0004] In addition, this application provides an electronic device, which includes the display component described in the above embodiments. The electronic device also includes a control circuit board, which is electrically connected to the electrochromic layer of the display component and is used to control the electrochromic layer to switch between the transparent state and the reflective state.

[0005] The display component and electronic device provided in this application incorporate an electrochromic layer within the display component. This layer is transparent when the screen is on or off, ensuring unaffected display. When the screen is off, the electrochromic layer is reflective, blocking light transmission to the panel with significant deformation and reflecting it directly off the electrochromic layer. This effectively conceals creases in the display component, achieving a virtually crease-free appearance. Since creases are a key performance indicator for foldable devices, this application's achievement of a virtually crease-free appearance significantly enhances the product's competitiveness.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

[0020] In existing foldable screen terminal products, the foldable display module is mainly composed of a large number of polymer materials laminated together. The macromolecular chain structure and unique thermal motion of polymer materials determine their viscoelastic properties, with creep being a typical characteristic. Creep refers to the phenomenon that the deformation of a material gradually increases over time under a certain temperature and constant external force (tension, pressure, torque, etc.). The creep process includes three types of deformation: elastic deformation, high-elastic deformation, and viscous flow. After the external force is removed, the material will always retain some irreversible deformation. Therefore, foldable screen terminal products that use a large number of polymer laminates will show creases after being bent for a period of time and then unfolded, especially when the screen is off, the creases will be more obvious.

[0021] This application provides a display component 10, such as... Figure 1As shown, the display assembly 10 includes a display panel 110 and an electrochromic layer 120 stacked together. The display panel 110 has a bent portion 111 and a non-bent portion 112 that can rotate around the bent portion 111. The electrochromic layer 120 at least covers the bent portion 111. When the display assembly 10 is in a screen-on state or a screen-off state, the electrochromic layer 120 is configured to be in a transparent state to allow light emitted from the display panel 110 to pass through. When the display assembly 10 is in a screen-off state, the electrochromic layer 120 is configured to be in a reflective state to reflect light toward the display panel 110.

[0022] Specifically, when the display component 10 is in a bright screen state or a screen-off display state, the display panel 110 can be in an illuminated state; when the display component 10 is in a screen-off state, the display panel 110 can be in a non-illuminated state. In some embodiments, when in a screen-off display state, information such as time and date can be displayed, for example, without lighting up the entire display panel. In this case, the display panel 110 can illuminate a portion of the display panel during a certain period of time, and another portion of the display panel can illuminate a portion of the display panel during a different period of time.

[0023] Optionally, when a first voltage is applied to the electrochromic layer 120, the electrochromic layer 120 is in a transparent state; when a second voltage is applied to the electrochromic layer 120, the electrochromic layer 120 is in a reflective state; the first voltage and the second voltage are different. Specifically, the first voltage and the second voltage are in opposite directions, and their absolute values ​​can be equal or unequal. For example, the first voltage can be a positive voltage with a value of 4V to 6V, and the second voltage can be a negative voltage with a value of -6V to -4V. Alternatively, both the first voltage and the second voltage can be positive, but with different values, such as the first voltage being 1 to 3V and the second voltage being 4 to 6V; or both the first voltage and the second voltage can be negative, but with different absolute values, such as the first voltage being -1 to -3V and the second voltage being -4 to -6V, etc.

[0024] The general process of crease formation is as follows: In the initial state, all the layers are very flat. After the display component 10 is bent and held for a period of time, the polymer materials such as the structural adhesive layer undergo creep. When the display component 10 is unfolded, due to the creep, some layers undergo irreversible deformation. The display panel 110 also undulates with the polymer layers that are bonded together. Light is reflected from the undulating display panel 110, and the phenomenon of crease undulation appears to the eye.

[0025] The electrochromic layer 120 of this application can block the crease of the bent portion 111 when the display component 10 is in a screen-off state, that is, when the display panel 110 does not emit light, effectively reducing the visual appearance of the crease.

[0026] Optionally, such as Figure 2 As shown, the electrochromic layer 120 includes a conductive layer 122, an ion storage layer 123, and a light control mirror layer 127 stacked sequentially.

[0027] Furthermore, the material of the light-controlled mirror layer 127 includes a magnesium-nickel alloy. The initial state of the light-controlled mirror layer 127, which uses a magnesium-nickel alloy (Mg-Ni alloy) thin film, is a mirror state, at which point the magnesium-nickel alloy is in a metallic state, and the electrochromic layer 120 is in a reflective state. When a voltage of approximately 5 volts is applied, the ion stored in the ion storage layer 123 (hydrogen tungsten bronze: H...)... x Hydrogen ions (H+) from WO3 move into the photosensitive mirror layer 127 (a metallic Mg-Ni alloy), causing the Mg-Ni alloy to hydrogenate and become nonmetallic. The photosensitive mirror layer 127 becomes transparent, and the electrochromic layer 120 is also transparent. When a voltage opposite to the aforementioned positive voltage is applied, i.e., approximately -5 volts, the hydrogen ions return to the ion storage layer 123 (tungsten oxide: WO3), and the photosensitive mirror layer 127 returns to its original mirror (metallic) state. Once ion implantation in either direction is completed, the photosensitive mirror layer 127 can be maintained in its current state (i.e., reflective or transparent) without a continuous voltage. In other words, this transition is non-volatile. Specifically, a voltage can be applied to the electrochromic layer 120 through the conductive layer 122.

[0028] Optionally, the electrochromic layer 120 includes a support layer 121, a conductive layer 122, an ion storage layer 123, an electrolyte layer 124, a buffer layer 125, a catalyst layer 126, and a light control mirror layer 127, which are stacked sequentially.

[0029] Furthermore, the support layer 121 can support other layers, the electrolyte layer 124 can serve as a medium for ion movement, the buffer layer 125 is used to improve the contact between different materials, and the catalyst layer 126 is used to promote ion movement.

[0030] Furthermore, the catalyst layer 126 can be made of palladium (Pd), the buffer layer 125 can be made of aluminum (Al), the electrolyte layer 124 can be made of solid electrolyte tantalum pentoxide (Ta2O5), the conductive layer 122 can be made of transparent indium tin oxide (ITO), and the support layer 121 can be made of transparent polyimide (CPI) or polyethylene terephthalate (PET) substrate.

[0031] Optionally, such as Figure 3 As shown, the display assembly 10 includes a support plate 150, a first protective layer 160, a display panel 110, an electrochromic layer 120, a second protective layer 170, and a third protective layer 180, which are stacked in sequence.

[0032] Furthermore, the display component 10 includes a bent area 130 and a non-bent area 140 that can rotate around the bent area 130.

[0033] Furthermore, the support plate 150 can be made of materials such as ultra-thin stainless steel (SUS), titanium alloy, or carbon fiber. The support plate 150 can have multiple openings 1501 located within the bending area 130 to facilitate folding of the bending area 130.

[0034] Furthermore, the first protective layer 160 can be made of polyimide (PI). Polyimide is a general term for aromatic heterocyclic polymers containing imide groups in their molecular structure, and it is one of the organic polymer materials with the best comprehensive performance. Polyimide is currently the most heat-resistant of the industrialized polymer materials, and it is widely used in high-tech fields as films, coatings, plastics, composite materials, adhesives, foams, fibers, separation membranes, liquid crystal alignment agents, photoresists, etc. As a special engineering material, polyimide has been widely used in aerospace, microelectronics, nanotechnology, liquid crystals, separation membranes, lasers, and other fields. The first protective layer 160 can protect the display panel 110, providing waterproofing and puncture resistance to ensure the normal operation of the display panel 110. In some other embodiments, the first protective layer 160 can also be made of transparent polyimide (CPI) or other materials.

[0035] Furthermore, the second protective layer 170 can be made of materials such as ultra-thin glass (UTG), polyethylene terephthalate (PET), or transparent polyimide (CPI). Ultra-thin glass (UTG) is typically between 0.1 and 1.2 mm thick, although some models achieve a thickness of less than 0.1 mm. Ultra-thin glass thicker than 1 mm is usually flat, while glass between 1 and 0.2 mm can be bent, and glass thinner than 0.2 mm can be folded. Ultra-thin glass (UTG) is scratch-resistant. In terms of light transmittance, thanks to the inherent advantages of glass, UTG can achieve over 90% light transmittance, providing a better viewing experience. Polyethylene terephthalate (PET) is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth, glossy surface, and is a common resin in everyday life. Polyethylene terephthalate (PET) possesses excellent mechanical properties, low gas and water vapor permeability, excellent barrier properties against gas, water, oil, and odors, high transparency, UV protection, and good gloss. Transparent polyimide (CPI) boasts high transparency, high heat resistance, and high mechanical strength, making it an important type of polyimide material. The rigidity of the imide rings and the regularity of the molecular chain in CPI contribute to its superior properties. The imide rings in the polyimide molecular chain are rigid and stable structural units, providing excellent mechanical and chemical stability. Furthermore, the regularity of the polyimide molecular chain is beneficial for the material's high-temperature and optical properties. Due to its high transparency, high heat resistance, and high mechanical strength, CPI is widely used in the manufacture of components for high-speed aircraft and space probes in the aerospace field. In addition, CPI is also widely used in the electronics field, such as in the manufacture of integrated circuit packaging materials and thin-film circuits for electronic components.

[0036] Furthermore, the third protective layer 180 can be made of polyethylene terephthalate (PET). The second protective layer 170 and the third protective layer 180 can be used to protect the display panel 110, while being transparent to allow light emitted from the display panel 110 to pass through. In some other embodiments, the third protective layer 180 can also be made of materials such as transparent polyimide (CPI).

[0037] When the display panel 110 is in an luminous state, a positive voltage is applied to the electrochromic layer 120 and then the power is turned off. At this time, the electrochromic layer 120 will be in a transparent state, and the light emitted by the display panel 110 will pass through the electrochromic layer 120 to achieve normal display. At the same time, the crease is not obvious when the screen is on. The positive voltage applied to the electrochromic layer 120 can be 4V to 6V. More specifically, the positive voltage can be 4V, 4.5V, 5.2V, 6V, or any value between the above voltages. Specifically, the positive voltage can be 5V.

[0038] When the display panel 110 is in an off-screen state and does not emit light, a negative voltage is applied to the electrochromic layer 120 and then the power is cut off, causing the electrochromic layer 120 to be in a reflective state. The negative voltage applied to the electrochromic layer 120 can be -6V to -4V, and further, the negative voltage can be -6V, -5.5V, -4.9V, -4V, or any value between the above voltages. Specifically, the negative voltage can be -5V. There are only three layers stacked on top of the electrochromic layer 120. Even if these three layers are folded and then unfolded, their irreversible creep deformation is very small. At this time, when light shines on the display component 10 and enters the display component 10, it will be reflected on the electrochromic layer 120. Since the crease of the electrochromic layer 120 is very small, it can achieve a crease-free effect to the eye.

[0039] Optionally, the second protective layer 170 on the electrochromic layer 120 can be ultra-thin glass (UTG). Ultra-thin glass has less creep deformation, which can reduce the creases generated by the three layers above the electrochromic layer 120 and further reduce the visual appearance of creases in the display component 10.

[0040] Optionally, the thickness of the electrochromic layer 120 is 10 μm to 100 μm. The thickness of the electrochromic layer 120 can be 10 μm, 20 μm, 35 μm, 50 μm, 80 μm, 100 μm, or any value between these thicknesses. Further, the thickness of the remaining layers of the display component 10 can be 15 μm to 50 μm.

[0041] Optionally, such as Figure 4 As shown, a first adhesive layer 190 is provided between the support plate 150 and the first protective layer 160, a second adhesive layer 191 is provided between the first protective layer 160 and the display panel 110, a third adhesive layer 192 is provided between the display panel 110 and the electrochromic layer 120, and a fourth adhesive layer 193 is provided between the second protective layer 170 and the third protective layer 180.

[0042] Furthermore, the third adhesive layer 192 and the fourth adhesive layer 193 can be made of optical adhesive, while the first adhesive layer 190 and the second adhesive layer 191 can be made of pressure-sensitive adhesive. Optical adhesive has high light transmittance and, when applied to the display panel 110, allows light emitted from the display panel 110 to pass through. In some other embodiments, the first adhesive layer 190 and the second adhesive layer 191 can also be made of optical adhesive.

[0043] Optical adhesive (OCA) is a substrate-free adhesive made from optical acrylic. It's a special adhesive used to bond transparent optical components (such as display covers and touch panels), boasting advantages like high purity, high light transmittance, high adhesion, and UV resistance. It's widely used in consumer electronics such as smartphones, laptops, and wearable devices, and is currently the best adhesive for touchscreens, gradually penetrating into automotive, education, commercial displays, smart wearables, and smart home applications. In touch display modules, OCA primarily functions in three ways: bonding different layers, filling ink step gaps, and enhancing display effects through full lamination. Using OCA for touchscreen module bonding and for bonding touchscreens and displays results in clearer, thinner, flatter, and more durable screens. In addition, OCA is also used for assembling lenses in optical lenses and bonding and assembling other optical components.

[0044] Pressure-sensitive adhesive (PSA) is a special type of adhesive. It is sensitive to pressure and can form a strong bond under relatively light pressure.

[0045] When in a reflective state, the electrochromic layer 120 can shield the creep deformation generated by the first adhesive layer 190, the second adhesive layer 191, the third adhesive layer 192, the display panel 110, and the first protective layer 160 in the bending area 130, greatly reducing the visual appearance of creases in the bending area 130 of the display assembly 10. Meanwhile, the second protective layer 170 can be made of ultra-thin glass, which is less prone to creep deformation. Therefore, no adhesive layer is needed between the second protective layer 170 and the electrochromic layer 120; a tight fit between the second protective layer 170 and the electrochromic layer 120 can be achieved simply by bonding their edges.

[0046] In some other embodiments, the electrochromic layer 120 may also be located between the second protective layer 170 and the third protective layer 180, or on the side of the third protective layer 180 opposite to the second protective layer 170.

[0047] Optionally, the area of ​​the electrostrictive layer 120 facing the display panel 110 can be the same as the area of ​​the display panel 110 facing the electrostrictive layer 120, and the electrostrictive layer 120 can completely cover the display panel 110. In some embodiments, the electrostrictive layer 120 can also simultaneously cover the bent portion 111 and a portion of the non-bent portion 112, or the electrostrictive layer 120 can only cover the bent portion 111 and not the non-bent portion 112.

[0048] Optionally, such as Figure 5 and Figure 6 As shown, the electrochromic layer 120 completely covers the display panel 110. The creep deformation of each stack above the electrochromic layer 120 is small, while the creep deformation of each stack below the electrochromic layer 120 is large. When the display component 10 is in the off state, the light incident on the display panel 110 is directly reflected by the electrochromic layer 120, so that the bending area 130 achieves the effect of no crease in the eyes.

[0049] Optionally, such as Figure 7 As shown, the second protective layer 170 has a groove 1701. The projection surface of the groove 1701 toward the display panel 110 coincides with the side of the bent portion 111 facing the second protective layer 170. The electrostrictive layer 120 is embedded in the groove 1701. In some other embodiments, the area of ​​the projection surface of the groove 1701 toward the display panel 110 may also be larger than the area of ​​the bent portion 111, so that the electrostrictive layer 120 can simultaneously cover the bent portion 111 and a portion of the non-bent portion 112.

[0050] Alternatively, in some embodiments, such as Figure 8 As shown, the display assembly 10 also includes a transparent layer 194, which is disposed in the same layer as the electrochromic layer 120. The electrochromic layer 120 covers the bent portion 111, and the transparent layer 194 covers the non-bent portion 112. Since the creases of the display assembly 10 are mainly located in the bent area 130, the visual appearance of the creases can be effectively reduced by simply blocking the bent area 130 when the display panel 110 is not emitting light.

[0051] In some other embodiments, when the display component 10 is in a screen-off display state, the display panel 110 may emit light only in a portion of its area to display information such as time. The light-emitting area of ​​the display panel 110 may be located in the non-bent portion 112. At this time, the electrochromic layer 120 covering the bent portion 111 may be in a reflective state to block the crease of the non-light-emitting bent portion 111.

[0052] Furthermore, the transparent layer 194 can be made of materials such as ultra-thin glass (UTG) or transparent polyimide (CPI).

[0053] This application also provides an electronic device, such as... Figure 9 As shown, the electronic device includes the display component 10 described in the above embodiments. The electronic device also includes a control circuit board 20, which is electrically connected to the electrochromic layer 120 of the display component 10 to control the electrochromic layer 120 to switch between a transparent state and a reflective state. The control circuit board 20 can apply an appropriate voltage to the electrochromic layer 120 while the display panel 110 is emitting light, causing the electrochromic layer 120 to be in a transparent state. The control circuit board 20 can also apply an appropriate voltage to the electrochromic layer 120 while the electronic device is off, causing the electrochromic layer 120 to be in a reflective state.

[0054] Further, please refer to Figure 10 The electronic device can be a mobile phone, tablet computer, laptop computer, or wearable device, etc. This embodiment illustrates a mobile phone as an example. The structure of this electronic device may include an RF circuit 910, a memory 920, an input unit 930, a display unit 940, a sensor 950, an audio circuit 960, a Wi-Fi module 970, and a power supply 990, all connected to the processor 980. The RF circuit 910, memory 920, input unit 930, display unit 940, sensor 950, audio circuit 960, and Wi-Fi module 970 are all included. The power supply 990 provides power to the entire electronic device.

[0055] Specifically, the RF circuit 910 is used to transmit and receive signals; the memory 920 is used to store data instruction information; the input unit 930 is used to input information, and may specifically include a touch panel 931 and other input devices 932 such as operation buttons; the display unit 940 may include a display panel 941, etc.; the sensor 950 includes infrared sensors, laser sensors, etc., used to detect user proximity signals, distance signals, etc.; the speaker 961 and the microphone 962 are connected to the processor 980 through the audio circuit 960 for transmitting and receiving sound signals; the Wi-Fi module 970 is used to receive and transmit Wi-Fi signals; and the processor 980 is used to process the data information of the electronic device. For specific structural features of the electronic device, please refer to the relevant descriptions in the above embodiments; detailed descriptions will not be provided here.

[0056] This application provides a display component 10 and an electronic device. An electrochromic layer 120 is disposed in the stack of layers of the display component 10, and its transparency and reflectivity are achieved by applying different voltages. When the display component 10 is in a screen-on or screen-off state, i.e., when the display panel 110 emits light, the electrochromic layer 120 is transparent to avoid affecting the display. When the display component 10 is in a screen-off state, i.e., when the display panel 110 does not emit light, the electrochromic layer 120 is reflective to block light transmission to the large-deformation display panel 110, allowing light to be directly reflected off the electrochromic layer 120, thereby achieving a visually crease-free appearance and greatly enhancing the product's competitiveness.
