Their applications are becoming increasingly widespread, including in electronic devices such as mobile phones, tablets, and wearable devices. While some display devices can achieve a mirror-like function, their contrast is extremely poor in high-light environments, affecting display quality. Summary of the Invention

[0006] A light-transmitting adjustment section is disposed at least partially opposite to the first metal section, and the light-transmitting adjustment section has a first state and a second state;

[0007] When the light transmission adjustment part is in the first state, the light transmission adjustment part allows external light to pass through to reach the first metal part, and allows the external light reflected by the first metal part to be transmitted to the outside of the display device through the light transmission adjustment part. When the light transmission adjustment part is in the second state, the light transmission adjustment part can block external light.

[0008] This application embodiment also provides a display device, which includes:

[0009] The light-emitting part is used to emit light signals; and

[0010] A metal anode is disposed on the side of the light-emitting part away from the light-emitting surface of the display device. The metal anode is adjacent to the light-emitting part, and the reflectivity of the metal anode is less than 20%.

[0014] A light-transmitting adjustment part is provided on the first metal part. The light-transmitting adjustment part is at least partially disposed opposite to the first metal part. The light-transmitting adjustment part has a first state and a second state. When the light-transmitting adjustment part is in the first state, the light-transmitting adjustment part allows external light to pass through to reach the first metal part, and causes the first metal part to reflect the external light through the light-transmitting adjustment part to the outside of the display device.

When the light transmission adjustment part is in the first state, external light can pass through, allowing it to illuminate the first metal part. The first metal part reflects the external light and transmits the reflected light through the light transmission adjustment part to the outside of the display device, thus enabling the display device to function as a mirror. In a high-intensity light environment, the light transmission adjustment part is set to the second state, blocking external light so that it cannot illuminate the first metal part. The first metal part does not reflect external light, allowing the display device to have better contrast and display effect. Attached Figure Description

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0037] This application provides a display device; please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram showing the light transmission adjustment unit in a first state in the display device provided in the embodiments of this application. Figure 2 This is a schematic diagram showing the light transmission adjustment section in a second state in a display device provided in an embodiment of this application. The display device 100 includes a first metal part 150 and a light transmission adjustment section 160. The first metal part 150 is capable of reflecting external light L1. The light transmission adjustment section 160 is at least partially disposed opposite to the first metal part 150, and the light transmission adjustment section 160 has a first state and a second state. When the light transmission adjustment section 160 is in the first state, external light L1 can be allowed to pass through, so that the external light L1 reflected by the first metal part 150 passes through the light transmission adjustment section 160 and is transmitted to the outside of the display device 100. When the light transmission adjustment section 160 is in the second state, it can block external light L1.

[0038] When the light transmission adjustment unit 160 is in its first state, external light L1 can pass through, allowing it to illuminate the first metal part 150. The first metal part 150 reflects the external light L1 and transmits the reflected light through the light transmission adjustment unit 160 to the outside of the display device 100, thus enabling the display device 100 to function as a mirror. In high-intensity light environments, the light transmission adjustment unit 160 is set to its second state, blocking the external light L1 from reaching the first metal part 150. The first metal part 150 does not reflect the external light L1, allowing the display device 100 to have better contrast and display effect.

[0039] The first metal part 150 has a high reflectivity, which is sufficient to enable the display device 100 to function as a mirror. For example, the reflectivity of the first metal part 150 can be greater than 70%, 80%, 85%, or 90%. The metal included in the first metal part 150 can be a high-reflectivity metal, such as silver (Ag) or molybdenum (Mo).

[0040] Please see Figure 3 , Figure 3 for Figure 1The diagram shows a first structural schematic of the light transmission adjustment unit in the display device. The light transmission adjustment unit 160 may include a first electrode sub-unit 1602, a light transmission adjustment sub-unit 1604, and a second electrode sub-unit 1606. The light transmission adjustment sub-unit 1604 is disposed between the first electrode sub-unit 1602 and the second electrode sub-unit 1606. The first electrode sub-unit 1602 and the second electrode sub-unit 1606 can change the light transmittance of the light transmission adjustment sub-unit 1604, causing the light transmission adjustment sub-unit 1604 to switch between a first state and a second state. The light transmittance of the light transmission adjustment sub-unit 1604 can be controlled by the first electrode sub-unit 1602 and the second electrode sub-unit 1606 disposed on both sides of the light transmission adjustment sub-unit 1604.

[0041] Optionally, the light transmission adjustment sub-section 1604 can be a liquid crystal sub-section, and the first electrode sub-section 1602 and the second electrode sub-section 1606 can change the arrangement of liquid crystal molecules in the liquid crystal sub-section so that the liquid crystal sub-section switches between a first state and a second state.

[0042] Understandably, when there is no voltage signal input to the first electrode sub-section 1602 and the second electrode sub-section 1606, the liquid crystal molecules in the liquid crystal sub-section are disordered, preventing external light from passing through and reaching the first metal section 150. Even if some external light reaches the first metal section 150 through other paths and is reflected, it still cannot pass through the liquid crystal sub-section to reach the outside of the display device 100. When there is a voltage signal input to the first electrode sub-section 1602 and the second electrode sub-section 1606, the liquid crystal molecules in the liquid crystal sub-section are arranged regularly, forming a light channel. External light can pass through this light channel to reach the first metal section 150, and external light reflected by the first metal section 150 can also pass through this channel to reach the outside of the display device 100.

[0043] The voltage signals of the first electrode sub-section 1602 and the second electrode sub-section 1606 can be set as needed, that is, the transmittance of the liquid crystal sub-section can be adjusted, thereby adjusting the external light transmittance and adjusting the mirror effect of the display device 100.

[0044] Optionally, the light transmission adjustment sub-section 1604 can be an electrochromic sub-section, and the first electrode sub-section 1602 and the second electrode sub-section 1606 can change the color of the electrochromic sub-section so that the electrochromic sub-section switches between a first state and a second state.

[0045] The color of the electrochromic sub-section can be changed according to the voltage of the first electrode sub-section 1602 and the second electrode sub-section 1606. For example, controlling the electrochromic sub-section to be colorless and transparent or to be a light-colored state with high light transmittance allows most of the external light illuminating the electrochromic sub-section to pass through. Alternatively, controlling the electrochromic sub-section to be black or a dark state with low light transmittance can block most of the external light illuminating the electrochromic sub-section.

[0046] The voltage signals of the first electrode sub-section 1602 and the second electrode sub-section 1606 can be set as needed, thereby adjusting the light transmittance of the electrochromic sub-section to adjust the external light transmittance and regulate the mirror effect of the display device 100. The color of the electrochromic sub-section can also be adjusted to achieve various mirror display effects.

[0047] It should be noted that the first electrode sub-part 1602 and the second electrode sub-part 1606 can be conductive materials with high light transmittance, such as indium tin oxide (ITO).

[0048] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. The display device 100 further includes a light-emitting portion 162 and a metal anode 152. The light-emitting portion 162 is used to emit light signals, and the light-emitting portion 162 can be an organic light-emitting material (OLED). The metal anode 152 is disposed on the side of the light-emitting portion 162 away from the light-emitting surface of the display device 100, and the metal anode 152 is adjacent to the light-emitting portion 162.

[0049] Understandably, the light signal emitted by the light-emitting part 162 needs to be transmitted to the outside of the display device 100 to realize the display function. The light-emitting part 162 itself also has a high light transmittance. Therefore, external light can also shine on the metal anode 152, and the metal anode 152 can also reflect at least part of the external light to the outside of the display device 100.

[0050] The reflectivity of the metal anode 152 can be high, such as being similar to that of the first metal part 150, so that it can cooperate with the first metal part 150 to realize the mirror function of the display device 100.

[0051] Understandably, since the metal anode 152 does not have a light transmission adjustment section 160 on the side facing the light-emitting part 162, the metal anode 152 will reflect external light, reducing the phone's contrast. To solve the problem of insufficient contrast of the display device 100 under high-intensity light, a circular polarizer can be added to the display device 100 to reduce the reflection of external light, such as controlling the reflectivity of the display device 100 to below 20%, 10%, or 5%, thereby allowing the display device 100 to be used normally under sunlight.

[0052] Optionally, the reflectivity of the metal anode 152 can be lower than that of the first metal part 150. The reflectivity of the metal anode 152 can be lower than a preset value, such as 50%, 40%, 30%, 20%, 10%, etc. The metal of the metal anode 152 can be a low-reflectivity metal, such as aluminum, calcium, magnesium, zinc, etc. Because the reflectivity of the metal anode 152 is low, the ability of the light-emitting area to reflect external light is fundamentally reduced, so that the display device 100 does not need to be equipped with a circular polarizer.

[0053] The thickness of the metal anode 152 can be set as needed, such as not exceeding 200 nanometers or 300 nanometers.

[0054] The metal anode 152 may include a three-layer structure. The three-layer structure is an ITO, a low-reflectivity metal, and an ITO layer. The first metal part 150 may be an ITO, a high-reflectivity metal, and an ITO three-layer structure, or a single high-reflectivity metal layer.

[0055] The metal anode 152 and the first metal part 150 are located on the same layer and are spaced apart. It is understood that the display device 100 provides the metal anode 152 corresponding to the light-emitting part 162. There are multiple metal anodes 152, spaced apart, with sufficient space between them to avoid affecting other structures. Utilizing this space, the first metal part 150 can be positioned to achieve a larger area without affecting the arrangement of other structures. Furthermore, the light signal emitted by the light-emitting part 162 needs to be transmitted to the outside of the display device 100; therefore, the structure between the light-emitting part 162 and the outside of the display device 100 is a highly transparent structure, and the structure between the first metal part 150 and the outside of the display device 100 is also a highly transparent structure. The first metal part 150 can easily reflect external light.

[0056] The display device 100 also includes a pixel definition section 164, which is disposed between the metal anode 152 and the first metal part 150 to separate the metal anode 152 and the first metal part 150.

[0057] Understandably, the pixel definition section 164 is used to space the light-emitting section 162. The pixel definition section 164 can also be reused to space the metal anode 152 and the first metal section 150, without the need to set other structures to space the metal anode 152 and the first metal section 150.

[0058] The pixel definition section 164 is also disposed between the light-emitting section 162 and the light-transmitting adjustment section 160 to separate the light-emitting section 162 and the light-transmitting adjustment section 160. It can also be understood that by using the pixel definition section 164 to accommodate the light-transmitting adjustment section 160, the size of the display device 100 will not be increased.

[0059] The first metal part 150 and the light transmission adjustment part 160 can be spaced apart by the pixel definition part 164.

[0060] In some other embodiments, please refer to Figure 5 , Figure 5 This is a second structural schematic diagram of the display device provided in the embodiments of this application. The light transmission adjustment unit includes a first electrode sub-unit 1602 and a light transmission adjustment sub-unit 1604. The first electrode sub-unit 1602, the light transmission adjustment sub-unit 1604, and a first metal part layer 150 are stacked. The light transmission adjustment sub-unit 1604 is disposed between the first electrode sub-unit 1602 and the first metal part 150. The first metal part 150, as a second electrode sub-unit, and the first electrode sub-unit 1602 can change the light transmittance of the light transmission adjustment sub-unit 1604, so that the light transmission adjustment sub-unit 1604 switches between a first state and a second state. It can be understood that the first metal part 150 and the light transmission adjustment sub-unit 1604 can be directly adjacent. The first metal part 150 can also serve as one side electrode for controlling the light transmission adjustment sub-unit 1604, and cooperate with the first electrode sub-unit 1602 to jointly control the light transmission adjustment sub-unit 1604. That is, the first metal part 150 can be reused as the second electrode sub-unit in the above embodiments.

[0061] Please combine Figure 6 , Figure 6 for Figure 4 or Figure 5 The diagram shows a partial structural schematic of the first metal part and the metal anode in the display device. The first metal part 150 has a first surface 1502 facing the light-emitting surface of the display device 100, and the metal anode 152 has a second surface 1522 facing the light-emitting surface of the display device 100. The area of ​​the first surface 1502 is larger than the area of ​​the second surface 1522.

[0062] To improve the overall reflectivity of the display device 100, the area of ​​the first surface 1502 of the first metal portion 150 is larger than the area of ​​the second surface 1522 of the metal anode 152. For example, the aperture ratio of the metal anode 152 is no more than 25%, and the aperture ratio of the first metal portion 150 is no less than 60%. Under the premise of ensuring the aperture ratio of the metal anode 152 and the metal etching process, the larger the aperture ratio of the first metal portion 150, the better.

[0063] Please continue reading. Figure 4 The display device 100 also includes a common electrode layer 170, which is disposed on the side of the light-emitting portion 162 away from the metal anode 152. The common electrode layer 170 and the metal anode 152 together drive the light-emitting portion 162 to emit light.

[0064] The light transmission adjustment unit 160 includes a first electrode sub-unit 1602, a light transmission adjustment sub-unit 1604, and a second electrode sub-unit 1606 arranged sequentially. The first electrode sub-unit 1602 is disposed on the side of the light transmission adjustment sub-unit 1604 facing the light-emitting surface of the display device 100, and is electrically connected to the common electrode layer 170 of the display device 100. The first electrode sub-unit 1602 can be powered by the common electrode layer 170, eliminating the need for a separate power supply line. A via can be provided between the first electrode sub-unit 1602 and the common electrode layer 170, and then electrically connected through a conductive structure within the via. The second electrode sub-unit 1606 can be powered by a power supply line.

[0065] Please see Figure 7 , Figure 7 This is a schematic diagram of a third structure of the display device provided in this application embodiment. The display device 100 further includes a protective layer 180, which covers the light-emitting part 162 and the light-transmitting adjustment part 160. The protective layer 180 can protect the light-emitting part 162 and the light-transmitting adjustment part 160 from damage by external objects and provide waterproofing, etc. The protective layer 180 can be a thin film encapsulation (TFE) layer. The protective layer 180 can include a multilayer structure. For example, please refer to... Figure 8 , Figure 8 for Figure 7 The diagram shows the structure of the protective layer in the display device. The protective layer 180 may include a first TFE inorganic water-blocking oxygen layer 182, a TFE organic buffer layer 184, and a second TFE inorganic water-blocking oxygen layer 186 arranged sequentially.

[0066] Please see Figure 9 , Figure 9 This is a third structural schematic diagram of the display device provided in this application embodiment. The display device 100 further includes a driver 190, which is connected to the light transmission adjustment unit 160. The driver 190 can control the light transmission adjustment unit 160 to switch between a first state and a second state according to a received instruction. When the driver 190 receives an external control instruction, it can control the light transmission adjustment unit 160 to be set to the first state or the second state according to the control instruction. The driver 190 can be a driver chip of the display device 100, or it can be other devices of the display device 100.

[0067] To better understand display devices, please continue reading. Figure 7 The display device 100 may include a substrate 110, a base 120, a driving layer 130, a planarization layer 140 (PLN), a metal anode 152, a light-emitting part 162, a common electrode layer 170 and a protective layer 180 arranged sequentially.

[0068] The substrate 110 can be a glass substrate or a resin substrate, etc., and can serve as a carrier for the display device 100. The substrate 120 can be a polyimide (PI) substrate or other substrates. A driving circuit structure, such as a thin-film transistor structure, is disposed within the driving layer 130. The thin-film transistor structure within the driving layer 130 is connected to the metal anode 152 and provides a voltage signal to the metal anode 152. The metal anode 152 and the common electrode layer 170 jointly drive the light-emitting part 162 to emit light. The planarization layer 140 can be used to obtain a planarized layer structure so that other structures can be disposed on the planarization layer 140. The driving layer 130 includes multiple layer structures, some of which can be disposed on the planarization layer 140. The structures of the metal anode, the light-emitting layer, and the protective layer 180 can be referred to the structures in the above embodiments, and will not be repeated here.

[0069] The display device 100 further includes a pixel defining section 164, which forms a pixel defining region, i.e., a region accommodating the light-emitting section 162. In this embodiment, the pixel defining section 164 also forms a region accommodating the light-transmitting adjustment section 160. By simultaneously forming a first region accommodating the light-emitting section 162 and a second region accommodating the light-transmitting adjustment section 160, the pixel defining section 164 can space the light-emitting section 162 and the light-transmitting adjustment section 160. In addition, the display device 100 also includes a first metal section 150, which can be disposed on the same layer as the metal anode 152, and the pixel defining section 164 can also space the first metal section 150 and the metal anode 152.

[0070] This design integrates a mirror display device with a conventional display device, allowing the device to function normally while also switching to a mirror display mode. In the light-emitting area, the high-reflectivity metal anode is replaced with a low-reflectivity metal anode, fundamentally reducing the reflection of ambient light and eliminating the need for a polarizer. In the non-light-emitting area, a mirror light path switch is created using a high-reflectivity first metal component, liquid crystal or electrochromic material, transparent metal, or ITO. When needed, this switch is activated, transforming the conventional display into a mirror display; when not needed, the switch is deactivated, allowing for normal operation. This design enhances the technological feel of the display and improves product presentation.

[0071] This application also provides a display device; please refer to [link / reference]. Figure 10 , Figure 10This is a fourth structural schematic diagram of the display device provided in the embodiments of this application. The display device 100 includes a light-emitting part 162 and a metal anode 152. The light-emitting part 162 is used to emit light signals. The metal anode 152 is disposed on the side of the light-emitting part 162 away from the light-emitting surface of the display device 100, and the metal anode 152 is adjacent to the light-emitting part 162. The reflectivity of the metal anode 152 is less than 20%.

[0072] Understandably, the light signal emitted by the light-emitting part 162 needs to be transmitted to the outside of the display device 100 to realize the display function. The light-emitting part 162 itself also has a high light transmittance. Therefore, external light can also shine on the metal anode 152, and the metal anode 152 can also reflect at least part of the external light to the outside of the display device 100.

[0073] If the reflectivity of the metal anode 152 is very high, it will reflect external light, reducing the phone's contrast. To solve the problem of insufficient contrast of the display device 100 under high light, a circular polarizer can be added to the display device 100 to reduce the reflection of external light, such as controlling the reflectivity of the display device 100 to below 10% or 5%, so that the display device 100 can be used normally under sunlight.

[0074] In this embodiment, the reflectivity of the metal anode 152 can be lower than 30%, 20%, or 10%, etc. The metal of the metal anode 152 can be a low-reflectivity metal, such as aluminum, calcium, magnesium, zinc, etc. Because the metal anode 152 has a low reflectivity, the ability of the light-emitting area to reflect external light is fundamentally reduced, so that the display device 100 does not need to be equipped with a polarizer.

[0075] The structure of the metal anode 152 can be referred to in the above embodiments, and will not be repeated here. Other structures of the display device 100 can be referred to in the above embodiments, and will not be repeated here.

[0076] This application also provides a method for manufacturing a display device. Please refer to [link to relevant documentation]. Figure 11 and Figure 12 , Figure 11 This is a schematic diagram illustrating a method for manufacturing a display device according to an embodiment of this application. Figure 12 for Figure 11 The display device is manufactured using the method shown. The method for manufacturing the display device includes:

[0077] 201, a substrate 110 is provided.

[0078] The substrate 110 can be a glass substrate or a resin substrate, or it can be a flexible substrate, such as a PI film.

[0079] 202. A first metal portion 150 is provided on the substrate 110, and the first metal portion 150 is capable of reflecting external light.

[0080] The first metal part 150 can have a high reflectivity, which is sufficient to enable the display device to function as a mirror. For example, the reflectivity of the first metal part 150 can be greater than 70%, 80%, 85%, or 90%. The metal included in the first metal part 150 can be a high-reflectivity metal, such as silver (Ag) or molybdenum (Mo).

[0081] 203. A light-transmitting adjustment portion 160 is provided on the first metal part 150. The light-transmitting adjustment portion 160 is at least partially disposed relative to the first metal part 150. The light-transmitting adjustment portion 160 has a first state and a second state. When the light-transmitting adjustment portion 160 is in the first state, the light-transmitting adjustment portion 160 allows external light to pass through to reach the first metal part 150, and the first metal part 150 reflects the external light through the light-transmitting adjustment portion 160 to the outside of the display device. When the light-transmitting adjustment portion 160 is in the second state, the light-transmitting adjustment portion 160 can block external light.

[0082] When the light-transmitting adjustment section 160 is in its first state, external light can pass through, allowing it to illuminate the first metal part 150. The first metal part 150 reflects the external light and transmits the reflected light through the light-transmitting adjustment section 160 to the outside of the display device, thus enabling the display device to function as a mirror. In high-intensity light environments, the light-transmitting adjustment section 160 is set to its second state, blocking external light from reaching the first metal part 150. The first metal part 150 does not reflect external light, resulting in better contrast and display effect for the display device.

[0083] The light-transmitting adjustment part provided on the first metal part includes:

[0084] A second electrode sub-part is provided on the first metal part;

[0085] A light transmission adjustment sub-section is provided on the second electrode sub-section; and

[0086] A first electrode sub-part is provided on the light transmission adjustment sub-part. The first electrode sub-part and the second electrode sub-part can change the light transmittance of the light transmission adjustment sub-part so that the light transmission adjustment sub-part switches between a first state and a second state.

[0087] The light transmittance of the light transmittance adjustment sub-section can be controlled by the first electrode sub-section and the second electrode sub-section located on both sides of the light transmittance adjustment sub-section.

[0088] In other embodiments, providing a light-transmitting adjustment portion on the first metal portion may further include:

[0089] A light-transmitting adjustment sub-part is provided on the first metal part; and

[0090] A first electrode sub-part is provided on the light transmission adjustment sub-part, and a first metal part serves as a second electrode sub-part. The first electrode sub-part can change the light transmittance of the light transmission adjustment sub-part, so that the light transmission adjustment sub-part switches between a first state and a second state.

[0091] The first metal part and the light transmission adjustment sub-part are directly adjacent to each other. The first metal part can also serve as one side electrode for controlling the light transmission adjustment sub-part, and cooperate with the first electrode sub-part to jointly control the light transmission adjustment sub-part. That is, the first metal part can be reused as the second electrode sub-part in the above embodiment.

[0092] Optionally, the light-transmitting sub-section can be a liquid crystal sub-section. Understandably, when there is no voltage signal input to the first and second electrode sub-sections, the liquid crystal molecules within the liquid crystal sub-section are disordered, preventing external light from passing through and reaching the first metal part. Even if some external light reaches the first metal part through other paths and is reflected, it still cannot pass through the liquid crystal sub-section to reach the outside of the display device. When there is a voltage signal input to the first and second electrode sub-sections, the liquid crystal molecules within the liquid crystal sub-section are arranged regularly, forming a light channel. External light can pass through this light channel to reach the first metal part, and external light reflected from the first metal part can also pass through this channel to reach the outside of the display device.

[0093] The voltage signals of the first electrode sub-section and the second electrode sub-section can be set as needed, which can adjust the light transmittance of the liquid crystal sub-section, thereby adjusting the external light transmittance and regulating the mirror effect of the display device.

[0094] Optionally, the light-transmitting sub-section can be an electrochromic sub-section. The color of the electrochromic sub-section can be changed according to the voltage of the first electrode sub-section and the second electrode sub-section. For example, controlling the electrochromic sub-section to be colorless and transparent or to be a light-colored state with high light transmittance allows most of the external light illuminating the electrochromic sub-section to pass through. Alternatively, the electrochromic sub-section can be controlled to be black or a dark state with low light transmittance, blocking most of the external light illuminating the electrochromic sub-section.

[0095] The voltage signals of the first and second electrode sub-sections can be set as needed, thereby adjusting the light transmittance of the electrochromic sub-section and thus adjusting the external light transmission rate to regulate the mirror effect of the display device. The color of the electrochromic sub-section can also be adjusted to achieve various mirror display effects.

[0096] It should be noted that the first electrode sub-section and the second electrode sub-section can be conductive materials with high light transmittance, such as indium tin oxide (ITO).

[0097] The manufacturing method of the display device may also include:

[0098] A metal anode is disposed on the substrate, and the reflectivity of the metal anode is less than that of the first metal part;

[0099] A light-emitting part is set on the metal anode.

[0100] The metal anode can be disposed on the same layer as the light-emitting part or on different layers. For example, the metal anode and the light-emitting part can be disposed first, and then the first metal part and the light transmission adjustment part can be disposed on the light-emitting part. It is understandable that the light signal emitted by the light-emitting part needs to be transmitted to the outside of the display device to realize the display function. The light-emitting part itself also has a high light transmittance. Therefore, external light can also shine on the metal anode, and the metal anode can also reflect at least part of the external light to the outside of the display device.

[0101] The reflectivity of the metal anode can be high, such as being similar to that of the first metal part, so that it can work with the first metal part to achieve the mirror function of the display device.

[0102] Understandably, since there's no light-regulating section on the side of the metal anode facing the light-emitting part, the metal anode will reflect external light, reducing the phone's contrast. To address the issue of insufficient contrast under high-intensity light, a circular polarizer can be added to the display device to reduce the reflection of external light, such as controlling the reflectivity to below 10% or 5%, thus allowing the display to function normally under sunlight.

[0103] Optionally, the reflectivity of the metal anode can be lower than that of the first metal part. The reflectivity of the metal anode can be lower than a preset value, such as 50%, 40%, 30%, 20%, 10%, etc. The metal of the metal anode can be a low-reflectivity metal, such as aluminum, calcium, magnesium, zinc, etc. Because the reflectivity of the metal anode is low, the ability of the light-emitting area to reflect external light is fundamentally reduced, allowing the display device to eliminate the need for a polarizer.

[0104] The thickness of the metal anode can be set as needed, such as not exceeding 200 nanometers or 300 nanometers.

[0105] The metal anode may include a three-layer structure. This three-layer structure consists of ITO, a low-reflectivity metal, and another ITO layer. The first metal layer may be an ITO, high-reflectivity metal, and another ITO layer, or a single high-reflectivity metal layer.

[0106] Please see Figures 13 to 19 , Figure 13 This is another schematic flowchart illustrating the manufacturing method of the display device provided in the embodiments of this application. Figures 14 to 19 for Figure 13 The apparatus formed at each stage of the manufacturing method of the display device shown. The manufacturing method of the display device includes:

[0107] 301, provides a substrate 110.

[0108] The substrate 110 can be a glass substrate or a resin substrate, etc.

[0109] 302, A substrate 120 is disposed on the substrate 110.

[0110] A substrate 120 is formed by coating the surface of the substrate 110 with polyimide (PI coating).

[0111] 303, A driving layer 130 is disposed on the substrate 120.

[0112] A driving layer 130 is obtained on a substrate 120 through processes such as chemical vapor deposition (CVD) and excimer laser annealing (ELA). The driving layer 130 may include a 3L layer forming a thin-film transistor and an intermediate insulating layer.

[0113] 304, Set a flattening layer 140 on the driving layer.

[0114] 305, A first metal portion 150 and a metal anode 152 are provided at intervals on a planarization layer 140.

[0115] Physical vapor deposition (PVD) and exposure development techniques are used on the planarization layer 140 to obtain a metal anode based on a low-reflectivity metal and a first metal part based on a high-reflectivity metal.

[0116] The metal anode 152 can be a multilayer structure, such as a three-layer structure of ITO / low-reflectivity metal / ITO. The low-reflectivity metal can be aluminum, calcium, magnesium, zinc, etc., and its thickness does not exceed 200 nm. The first metal part 150 can be a three-layer structure of ITO / high-reflectivity metal / ITO, or it can be a single layer of high-reflectivity metal, such as silver, molybdenum, etc. For example, the reflectivity of the high-reflectivity metal is >90%.

[0117] The area of ​​the first metal portion 150 is larger than the area of ​​the metal anode 152. For example, the aperture ratio of the metal anode 152 of the low reflectivity metal can not exceed 25%, and the aperture ratio of the first metal portion 150 of the high reflectivity metal is not less than 60%. Under the premise of ensuring the aperture ratio 152 of the metal anode and the metal etching process, the larger the area of ​​the first metal portion 150, the better.

[0118] 306. A pixel definition portion 164 is provided on the first metal portion 150 and the metal anode 152, and a first groove relative to the first metal portion 150 and a second groove relative to the metal anode 152 are formed.

[0119] The pixel definition section 164 has two main functions: one is to form the pixel definition area, i.e., the defined area of ​​the light-emitting section, and the other is to form the defined area of ​​the light-transmitting adjustment section.

[0120] 307, a light-transmitting adjustment part 160 is provided in the first groove, and a light-emitting part 162 adjacent to the metal anode is provided in the second groove.

[0121] In this process, a layer of liquid crystal or electrochromic material can be coated on the surface of the first metal part 150, and then a layer of transparent metal electrode or ITO can be deposited on the liquid crystal or electrochromic material to complete the fabrication of the light transmission adjustment part 160. It is understood that the pixel definition part 164 can expose the first metal part 150, and then the liquid crystal or electrochromic material and the first electrode sub-part are sequentially disposed on the first metal part 150 to form the light transmission adjustment part 160. The first metal part 150 can be reused as the second electrode sub-part, meaning that the first metal part 150, as the second electrode sub-part, and the first electrode sub-part jointly drive the liquid crystal or electrochromic material. Alternatively, the pixel definition part 164 can cover the first metal part 150, and then the second electrode sub-part, the liquid crystal or electrochromic material, and the first electrode sub-part are sequentially disposed on the pixel definition part 164 to form the light transmission adjustment part 160.

[0122] The metal anode 152 and the first metal part 150 are located on the same layer and spaced apart. The display device provides metal anodes 162 corresponding to the light-emitting part 162. Multiple metal anodes 152 are provided, spaced apart, with sufficient space between them. This space is used to arrange the first metal part 150, resulting in a larger area without affecting the arrangement of other structures. Furthermore, the light signal emitted by the light-emitting part 162 needs to be transmitted to the outside of the display device; therefore, the structure between the light-emitting part 162 and the outside of the display device is highly transparent, as is the structure between the first metal part 150 and the outside of the display device. The first metal part 150 can easily reflect external light.

[0123] The pixel defining unit 164 is used to space the light-emitting unit. The pixel defining unit 164 can also be reused to space the metal anode 152 and the first metal part 150, eliminating the need for additional structures to separate the metal anode 152 and the first metal part 150. The pixel defining unit 164 can also space the light-emitting unit 162 and the light-transmitting adjustment unit 160. By accommodating the light-transmitting adjustment unit 160 using the pixel defining unit 164, the size of the display device is not increased.

[0124] 308. A common electrode layer 170 is provided on the light-emitting part 162, and the common electrode layer 170 covers the light-emitting part 162 and the light-transmitting adjustment part 160.

[0125] The common electrode layer 170 and the metal anode 162 jointly drive the light-emitting part 162 to emit light. The light-transmitting adjustment part 160 includes a first electrode sub-part, a light-transmitting adjustment sub-part, and a second electrode sub-part arranged sequentially. The first electrode sub-part is located on the side of the light-transmitting adjustment sub-part facing the light-emitting surface of the display device, and is electrically connected to the common electrode layer 170 of the display device. The first electrode sub-part can be powered by the common electrode layer 170, eliminating the need for a separate power supply line. A via can be provided between the first electrode sub-part and the common electrode layer 170, and then electrically connected through a conductive structure within the via. Alternatively, the first electrode sub-part and the common electrode layer 170 can be directly adjacent. The second electrode sub-part can be powered by a power supply line.

[0126] 309. A protective layer 180 is provided on the common electrode layer 170.

[0127] The protective layer 180 can protect the common electrode layer 170, the light-emitting part 162, and the light-transmitting adjustment part 160 from damage by external objects and provide waterproofing. The protective layer 180 can be a thin film encapsulation (TFE) layer. The protective layer 180 can include a multilayer structure. For example, the protective layer can include a first TFE inorganic water-blocking oxygen layer, a TFE organic buffer layer, and a second TFE inorganic water-blocking oxygen layer arranged sequentially.

The processor 400 can automatically control the light transmission adjustment unit 160 to switch between the first state and the second state upon receiving user operation or environmental parameters. For example, when the processor receives a first operation command from the user, the processor controls the light transmission adjustment unit to be in the first state; when the processor receives a second operation command from the user, the processor controls the light transmission adjustment unit to be in the second state. As another example, when the display device is in display mode and the processor obtains information that the electronic device is in a high-brightness environment, the processor controls the light transmission adjustment unit to be in the second state.

Alternatively, the display device 100 can consist entirely of identical display areas. The optical sensor, such as the camera, can move between the inside and outside of the housing via a retractable drive mechanism, allowing the camera to move outside the housing to acquire external light signals for imaging, enabling functions such as selfies.
