Description

Technical Field

[0001] This application belongs to the field of electronic product technology, specifically relating to a display panel, a privacy control method, and an electronic device. Background Technology

[0002] With the development of internet technology, people are using electronic products more and more frequently, and in order to protect their personal privacy, people's demand for privacy protection displays is also increasing.

[0003] Privacy protection is a special requirement for display panels. For viewers directly facing the screen, the display appears normal, but for viewers at certain angles, the panel brightness is significantly reduced or color information is noticeably lost, thus improving the privacy of the displayed information. Current privacy protection technology primarily achieves this by mechanically adding a privacy film to the outer screen. This film works on the principle of blinds, adding a privacy layer to a regular film structure. Within this layer, parallel arranged grating structures control the angle of light, narrowing the screen's wide viewing angle. However, the privacy layer blocks some screen light, resulting in a 30% reduction in brightness compared to a screen without a privacy layer at the same brightness level. To maintain screen brightness, additional screen brightness must be increased, leading to increased power consumption. Summary of the Invention

[0004] The purpose of this application is to provide a display panel, a privacy control method, and an electronic device that can solve the problem that existing privacy solutions increase screen power consumption.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0009] A fixed structure is set at the other end of the grating channel;

In the second state, the second end of the light-shielding unit extends out from the storage structure and is connected to the fixed structure.

In the second state, the second end of the light-shielding unit extends from the storage structure and connects to the fixing structure, the light-shielding unit is arranged within the grating channel, and the grating channel is light-shielding. Thus, in application scenarios where the user needs to enable the privacy function, the privacy layer structure can be controlled to be in the second state; in application scenarios where the user does not need to enable the privacy function, the privacy layer structure can be controlled to be in the first state.

[0039] 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0041] The control method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0042] Please refer to Figures 1 to 12 This invention provides a display panel, comprising:

[0043] The glass cover 1 has a privacy layer structure 10, which includes a plurality of grating channels 101 arranged side by side at intervals along the first direction X, and each grating channel 101 is used to install a light-shielding unit 102.

[0044] The storage structure 11 is disposed at one end of the grating channel 101 and is fixedly connected to the first end of the light-shielding unit 102;

[0045] The fixing structure 12 is located at the other end of the grating channel 101;

[0046] The driving structure 13 is used to control the privacy screen structure 10 to switch between a first state and a second state. In the first state, the light-shielding unit 102 retracts into the storage structure 11, and the grating channel 101 is in a light-transmitting state. In the second state, the second end of the light-shielding unit 102 extends out from the storage structure 11 and is connected to the fixing structure 12. The light-shielding unit 102 is arranged in the grating channel 101, and the grating channel 101 is in a light-shielding state.

[0047] Optionally, the first direction X is the length direction of the screen or the width direction of the screen.

[0048] Optionally, the glass cover 1 can be provided with a double privacy layer structure, in which multiple grating channels 101 in one privacy layer structure are arranged at intervals along the length direction of the screen, and multiple grating channels 101 in the other privacy layer structure are arranged at intervals along the width direction of the screen. In this way, the display panel can have privacy protection function in multiple directions.

[0049] For example, Figure 1 The diagram shows a cross-sectional view of the display panel, which includes the following layers stacked from top to bottom: a glass cover plate 1, a touch layer, a panel, and a back plate (iron plate); wherein, the touch panel (TP) glass is the touch layer, and the display panel includes: a color filter (CF) glass, a thin film transistor (TFT) glass, an upper brightness enhancement film (UP Prism), a lower brightness enhancement film (Down Prism), a diffuser, a light guide plate (LGP), and a backlight module.

[0050] See Figure 1 and Figure 10 The privacy screen structure 10 includes multiple grating channels 101 arranged in parallel along the length of the screen. The grating channels 101 are spaced apart, so that when the light-shielding unit 102 is arranged in the grating channel 101, a strip-shaped light-transmitting area can be formed between the spaced grating channels 101.

[0051] Optionally, such as Figures 1 to 5 In this structure, the grating channel 101 is a cylindrical channel formed by hollowing out the interior of the glass cover plate 1. Under the driving action of the driving structure 13, the light-shielding unit 102 can move within the grating channel 101 to switch the privacy layer structure 10 between a first state and a second state. Specifically, when the privacy function is not activated, the light-shielding unit 102 is stored in the storage structure 11. When the privacy function is activated, the first end of the light-shielding unit 102 is connected to the storage structure 11, and the second end of the light-shielding unit 102 extends out from the storage structure 11 and moves along the grating channel 101 to connect with the fixing structure 12. At this time, the light-shielding unit 102 is arranged within the grating channel 101, and the grating channel 101 is in a light-shielding state.

[0052] In the above embodiments, in application scenarios where the user needs to enable the privacy function, the privacy layer structure can be controlled to be in the second state; in application scenarios where the user does not need to enable the privacy function, the privacy layer structure can be controlled to be in the first state. This allows the privacy function to be intelligently enabled or disabled according to the user's needs, reducing the screen's power consumption.

[0053] like Figures 2 to 4 In some embodiments, the driving structure 13 includes:

[0054] The driving coil 130 is wound around the outer periphery of the plurality of grating channels 101, and the driving coil 130 is made of transparent material.

[0055] Multiple first magnetic elements 131, with a first magnetic element 131 provided at the second end of each light-shielding unit 102;

[0056] The rotating structure 132 is wound around the first end of the plurality of light-shielding units 102;

[0057] Power supply module 133 is used to supply power to drive coil 130 and rotating structure 132;

[0058] When the power supply module 133 is charging the drive coil 130 in the forward direction, the drive coil 130 drives the first magnetic element 131 to move along the grating channel 101 toward the fixed structure 12, and the rotating structure 132 rotates along the direction of releasing the light-shielding unit 102 until the first magnetic element 131 is connected to the fixed structure 12, and the privacy layer structure 10 is in the second state.

[0059] When the power supply module 133 reverse charges the drive coil 130, the rotating structure 132 rotates in the direction of the recycling light shielding unit 102. The rotating structure 132 and the drive coil 130 drive the first magnetic element 131 to separate from the fixed structure 12 until the privacy layer structure 10 is in the first state.

[0060] Optionally, the driving coil 130 is a coil formed by conductive glass surrounding the periphery of multiple grating channels 101. The conductive glass body is transparent, and a conductive film is attached to its surface to conduct electricity. The driving coil 130 includes two conductive ports: one conductive port is the initial conductive disconnection located at the starting point, and the other conductive port is the end conductive port after the driving coil 130 winds to the top of the screen and then flows down in a straight line along the grating channel direction; the initial conductive port is connected to the power line c1, and the end conductive port is connected to the ground line c2.

[0061] It should be noted that the rest of the glass cover plate 1, except for the grating channel 101 and the drive coil 130, is made of ordinary glass.

[0062] The power supply module 133 provides forward or reverse current to the drive coil 130 through the start conductive port and the end conductive port of the drive coil 130. Optionally, when the power supply module provides forward current to the drive coil 130, the drive coil 130 generates a magnetic force toward the fixed structure 12; when the power supply module provides reverse current to the drive coil 130, the drive coil 130 generates a magnetic force away from the storage structure 11.

[0063] Optionally, the rotating structure 132 includes:

[0064] Motor 1320, which is electrically connected to power supply module 133;

[0065] The rotating shaft 1321 is fixedly connected to the motor 1320, and the first ends of the plurality of light-shielding units 102 are wound around the rotating shaft 1321.

[0066] For example, such as Figure 5 In the storage space 110, the rotating shaft 1321 is located at the end of the storage space 1321. The rotating shaft 1321 is connected to the motor 1320, which is a micro motor used to provide rotational torque to the rotating shaft 1321. Driven by the motor 1320, the rotating shaft 1321 can rotate clockwise or counterclockwise. When the rotating shaft 1321 rotates clockwise, it winds the first end of the light-shielding unit 102. When the rotating shaft 1321 rotates counterclockwise, it releases the wound light-shielding unit 102.

[0067] Thus, when the user activates the privacy function, when the power supply module 133 provides positive current to the drive coil 130, the drive coil 130 generates a magnetic force toward the fixed structure 12, and at the same time the rotating shaft 1321 rotates counterclockwise to release the wound light-shielding unit 102. Under the magnetic force of the drive coil 130, the light-shielding unit 102 moves along the grating channel 101 to connect with the fixed structure 12.

[0068] When the user disables the privacy function, when the power supply module provides reverse current to the drive coil 130, the drive coil 130 generates a magnetic force toward the storage structure 11. At the same time, the rotating shaft 1321 rotates clockwise, and the first end of the wound light-shielding unit 102, under the action of the pulling force of the rotating shaft 1321 and the magnetic force of the drive coil 130, retracts the light-shielding unit 102 along the grating channel 101 into the storage structure 11.

[0069] In an optional embodiment, the light-shielding unit 102 includes: an elastic pull cord 1020 and black foam 1021 attached to the elastic pull cord 1020.

[0070] See Figure 7 The light-blocking unit 102 includes two parts. One part is a first magnetic element at the top, which is the same size as the grating channel 101 and can pass through the grating channel 101 perfectly. The other part is an elastic pull cord 1020 connected to the first magnetic element. Optionally, the elastic pull cord 1020 is a non-magnetic spring cord with elasticity and is not easy to break. The cord is covered with black foam 1021 that can completely fill the grating channel 101.

[0071] In this embodiment, because the black foam 1021 has very high compressibility, it can be quickly compressed and pulled into the storage structure 11 under the elastic tension of the elastic cord 1020.

[0072] In some embodiments, the storage structure 11 includes a plurality of storage spaces 110, and the first opening end of each storage space 110 corresponds to a grating channel 101;

[0073] The first opening end is provided with a first receiving area 111; in the first state, the first magnetic element 131 is received in the first receiving area 111, and the light-shielding unit 102 retracts into the storage space 110.

[0074] Alternatively, to prevent the light-shielding unit 102 from becoming entangled within the storage structure 11, the storage space 110 is a curved cylindrical space.

[0075] For example, in such Figure 5 and Figure 6 In the cross-sectional view shown, each storage space 110 corresponds to a grating channel 101. Multiple cylindrical storage spaces 110 are arranged side by side in the storage structure 11. Each storage space 110 is used to store a light-shielding unit 102. The first opening end of each storage space 110 corresponds to a grating channel 101 in the glass cover plate 1. The first opening end of the storage space 110 is thicker than the subsequent space, forming a first receiving area 111. After the first magnetic element 131 enters the first receiving area 111, due to the thinner subsequent space, the first magnetic element 131 is stuck in the first receiving area 111 and remains stationary.

[0076] It should be pointed out that, Figure 6 The storage space 110 shown only shows the elastic drawstring 1020; the black foam 1021 is not shown.

[0077] In some embodiments, the fixing structure 12 includes a second magnetic element 120; in the second state, the first magnetic element 131 is attracted and connected to the second magnetic element 120.

[0078] For example, such as Figure 8 and Figure 9 In the process, the main body of the fixing structure 12 is made of a hard, opaque material such as plastic or plastic that is not attracted by a magnet. The second magnetic element is a long strip magnet embedded in the plastic filling, which is used to attract and connect the first magnetic element 131 in the first accommodating area 111 to fix the first magnetic element 131.

[0079] In some embodiments, the fixing structure 12 further includes a second receiving area 121 corresponding to each of the first magnetic elements 131; in the second state, the first magnetic elements 131 are received in the second receiving area 121.

[0080] For example, such as Figure 8 and Figure 9 In the fixed structure 12, there are multiple cylindrical grooves inside the main body, forming multiple second receiving areas 121, and each light-shielding unit 102 corresponds to one second receiving area 121. In this way, the displacement of the first magnetic element 131 can be avoided.

[0081] In some embodiments, the power supply module 133 includes:

[0082] The first switching element 1330 and the second switching element 1331, the first pin a1 of the first switching element and the second pin b2 of the second switching element are respectively connected to the voltage input terminal, and the second pin a2 of the first switching element and the first pin b1 of the second switching element are respectively grounded;

[0083] Grounding wire C2 is connected to the common terminal of the first switching element 1330.

[0084] Power line C1 is electrically connected to the common terminal of the second switching element 1331.

[0085] The control line V_ctrl is connected to the first switching element 1330 and the second switching element 1331 respectively, and is used to input a first voltage or a second voltage to the first switching element 1330 and the second switching element 1331; wherein, when the first voltage is input to the control line, the power supply module 133 charges the drive coil 130 in the forward direction, and when the second voltage is input to the control line, the power supply module 133 charges the drive coil 130 in the reverse direction.

[0086] Optionally, the main FPC extension of the screen forms an extension FPC1333, which is the main structure of the power supply module 133. The extension FPC1333 includes a power line c1 and a ground line c2. Most of the area of ​​the extension FPC1333 is embedded in the plastic filling of the storage structure 11.

[0087] See Figure 11 The extended FPC1333 has two areas near the glass cover plate 1: a conductive silver paste access area d1 and a motor access area d2. The surface of both areas has exposed copper and is connected to the power line c1 and the ground line c2. The conductive silver paste access area d1 supplies power to the drive coil 130 within the glass cover plate 1; the motor access area d2, located near the bottom of the storage structure 11, supplies power to the motor 1320. The area containing d3 is the IC area of ​​the power supply module 133, and the area containing d4 is the screen BTB wiring.

[0088] In its specific implementation, the main circuit components of the power supply module 133 are located on the main FPC of the screen, mainly including a first switching element 1330 and a second switching element 1331. The first switching element 1330 and the second switching element 1331 use the same Vcc power supply and the same V_ctrl control line. The first pin a1 of the first switching element and the second pin b2 of the second switching element are respectively connected to the voltage input terminal V_in, and the second pin a2 of the first switching element and the first pin b1 of the second switching element are respectively grounded to GND.

[0089] When the privacy protection function is activated, Vcc is powered on first, activating the first switching element 1330 and the second switching element 1331. V_ctrl sends a high-level control command, causing the first switching element 1330 to point to pin a1 and the second switching element 1331 to point to pin b1. This means power line c1 is connected to V_in, and ground line c2 is grounded to GND, causing the drive coil 130 to charge in the forward direction. Motor 1320 drives shaft 1321 to release the light-shielding unit 102. After the privacy protection function is activated, V_in is de-energized, then V_ctrl, and finally Vcc.

[0090] When the privacy screen function is disabled, Vcc is powered on first, activating the switch. V_ctrl sends a low-level control command, causing the first switching element 1330 to point to pin a2 and the second switching element 1331 to point to pin b2. This connects the power supply line to GND and the ground line to V_in, causing the drive coil 130 to charge in reverse, and the motor 1320 to drive the shaft 1321 to wind the light-shielding unit 102. After the privacy screen function is disabled, V_in is de-energized, then V_ctrl, and finally Vcc.

[0091] In addition, embodiments of this application also provide an electronic device, including the display panel described above.

[0092] Optionally, electronic devices include, but are not limited to: computers, mobile phones, digital products, home appliances, office equipment, game consoles, etc.

[0093] In this embodiment, when the user needs to enable the privacy function, the electronic device can control the privacy layer structure in the display panel to be in a second state. In the second state, the second end of the light-shielding unit 102 extends from the storage structure 11 and is connected to the fixing structure 12. The light-shielding unit 102 is arranged inside the grating channel 101, and the grating channel 101 is in a light-shielding state. When the user does not need to enable the privacy function, the privacy layer structure in the display panel can be controlled to be in a first state. In the first state, the light-shielding unit 102 retracts into the storage structure 11, and the grating channel 101 is in a light-transmitting state. This allows the privacy function to be intelligently enabled or disabled according to user needs, reducing screen power consumption.

[0094] See Figure 13 This application provides a privacy control method applied to the above-mentioned display panel, comprising the following steps:

[0095] Step 101: Receive the first input.

[0096] The first input is a pre-set input, which may include, but is not limited to, at least one of the following: click input, press input, long press input, pinch input, drag input, slide input, and swipe input. That is to say, the first input may be one of the above inputs, or it may be a combination of two or more of the above inputs.

[0097] Step 102: When the first input is used to trigger the opening of the privacy function, in response to the first input, the privacy layer structure in the display panel is controlled to be in the second state.

[0098] For example, when a user presses the first button to "activate privacy function," the processor of the electronic device sends instructions to the power supply module 133 and the motor 1320. The power supply module 133 supplies power to the drive coil 130 in the forward direction, and the motor 1320 drives the rotating shaft 1321 to rotate counterclockwise, releasing the light-shielding unit 102 until the first magnetic element 131 is connected to the fixed structure 12, and the privacy layer structure 10 is in the second state. After the privacy layer structure 10 is in the second state, the power supply module 133 stops outputting voltage, the drive coil 130 and the motor 1320 stop working, the light-shielding unit 102 fills the grating channel 101, completing the construction of the privacy layer and enabling the privacy function.

[0099] Step 103: When the first input is used to trigger the disabling of the privacy function, in response to the first input, the privacy layer structure 10 in the display panel is controlled to be in a first state.

[0100] For example, when a user presses the second button to "turn off privacy function," the processor of the electronic device sends instructions to the power supply module 133 and the motor 1320. The power supply module 133 supplies reverse power to the drive coil 130, and the motor 1320 drives the rotating shaft 1321 to rotate clockwise, winding the light-shielding unit 102. The rotating structure 132 and the drive coil 130 drive the first magnetic element 131 to separate from the fixed structure 12 until the privacy layer structure 10 is in the first state. After the privacy layer structure 10 is in the first state, the power supply module 133 stops outputting voltage, the drive coil 130 and the motor 1320 stop working, and the light-shielding unit 102 has been retracted into the storage structure 11, thus turning off the privacy function.

[0101] In the above embodiments, in application scenarios where the user needs to enable the privacy function, the privacy layer structure can be controlled to be in the second state; in application scenarios where the user does not need to enable the privacy function, the privacy layer structure can be controlled to be in the first state. This allows the privacy function to be intelligently enabled or disabled according to the user's needs, reducing the screen's power consumption.

[0102] For example, suppose that the grating channel 102 extends along the length direction of the screen, and the plurality of grating channels 102 are arranged at intervals along the width direction of the screen.

[0103] See Figure 14 Methods to enable the privacy feature include:

[0104] Step 1401: The user selects to enable the privacy protection function;

[0105] Step 1402: The switching power supply Vcc is turned on, and the control line sends a high level to the first switching element 1330 and the second switching element 1331. The power line c1 of the extended FPC1333 is connected to the power supply, and the ground line c2 is grounded.

[0106] Step 1403: Drive coil 130 is energized in the forward direction to generate an upward magnetic force along the length of the screen, drive motor 1320 is energized, and shaft 1321 begins to release light-shielding unit 102.

[0107] Step 1404: The light-shielding unit 102 moves with the first magnetic element 131, and fills the grating channel 102 to form a grating. Finally, the first magnetic element 131 reaches the fixing structure 12 and is fixed.

[0108] Step 1405: V_in is powered off, V_ctrl is powered off, Vcc is powered off, the drive coil 130, motor 1320, first switching element 1330 and second switching element 1331 stop working, and the privacy screen function is activated.

[0109] See Figure 15 Methods to disable the privacy feature include:

[0110] Step 1501: The user selects to disable the privacy feature;

[0111] Step 1502: The switching power supply Vcc is turned on, and the control line sends a low level to the first switching element 1330 and the second switching element 1331. The power line c1 of the extended FPC1333 is grounded, and the ground line c2 is connected to the power supply.

[0112] Step 1503: Drive coil 130 is energized in reverse to generate a magnetic force downward along the length of the screen, motor 1320 is energized, and shaft 1321 begins to wind the light-shielding unit 102.

[0113] Step 1504: The light-shielding unit 102 moves with the first magnetic element 131 until the first magnetic element 131 and the light-shielding unit 102 are recycled into the storage structure 11.

[0114] Step 1505: Power off V_in, V_ctrl, and Vcc. Drive coil 130, motor 1320, first switching element 1330, and second switching element 1331 stop working, and the privacy screen function is turned off.

[0115] In some embodiments, when the privacy protection function is enabled, the method further includes:

[0116] Receives the user's photoelectric fingerprint input;

[0117] In response to the photoelectric fingerprint input, the privacy screen structure is controlled to switch from the first state to the second state;

[0118] When the photoelectric fingerprint input is determined to be finished, the privacy layer structure is controlled to switch from the second state back to the first state.

[0119] It should be noted that privacy films can block some of the screen light, preventing users from fully recognizing fingerprint information when using in-display fingerprint sensors, thus making it impossible for users to use in-display fingerprint sensors.

[0120] In the above embodiments, when the privacy feature is enabled, it automatically disables when the user needs to use the in-display fingerprint sensor, and automatically re-enables when the fingerprint sensor usage is finished. This prevents the privacy layer structure from interfering with the user's use of the in-display fingerprint sensor.
