[0055] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0057] Near Field Communication (NFC) is a short-range, high-frequency wireless communication technology. NFC enables various functions, including card reading, card emulation, and point-to-point communication. Card reading refers to the contactless reading of external cards. In this mode, the NFC component enters a card reading mode, which alternates between a signal transmission period and a listening period. During the transmission period, the NFC component sends signals; during the listening period, it listens for external feedback signals.

[0058] However, during the signal transmission period, the near-field communication component will have a large current when transmitting signals, which may affect the normal display of the display component.

[0059] Specifically, during display, the display component cycles through an image refresh period and an image hold period. During the image refresh period, the drive circuit in the display component controls the image refresh via electrical signals. After the image refresh is complete, it enters the image hold period, maintaining the refreshed image. If the signal transmission period of the near-field communication component overlaps with the image refresh period of the display component (e.g., partially or completely), the large current in the near-field communication component may significantly affect the drive circuit in the display component, preventing the display component from refreshing the image correctly, potentially causing problems such as image flickering.

[0060] The refresh cycle mentioned above refers to the time it takes for the display component to display one frame of an image. Correspondingly, the display component can display multiple frames of images at a preset refresh rate. The refresh cycle can be the reciprocal of the refresh rate, such as... Figure 1 As shown, Figure 1 This is a diagram illustrating a refresh cycle for an image component. Figure 1 The diagram illustrates three consecutive refresh cycles F1, F2, and F3, each including an image refresh period and an image hold period (e.g., image refresh period F11 and image hold period F12 for refresh cycle F1). For example, when the display component's refresh rate is 60 Hz (refresh cycle 1 / 60 second), the display component displays 60 frames per second, with each frame displayed for 1 / 60 second. Figure 1 Taking the refresh cycle F1 as an example, in the refresh cycle F1, the image can first be refreshed in the image refresh period F11. After the image refresh is completed, it will enter the image hold period F12 and keep the image displayed. For example, the image refresh period F11 can be the first 1 / 300th of a 1 / 60th second, and the image hold period F12 can be the last 4 / 300th of a 1 / 60th second.

[0061] In addition, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the card reading mode of the near-field communication component mentioned above. Figure 2 The diagram illustrates two consecutive polling cycles, N1 and N2. Each polling cycle may include a signal transmission period and a listening period (e.g., polling cycle N1 includes a signal transmission period P1 and a listening period L1). During the signal transmission period, the near-field communication component can transmit at least one polling signal, such as NFC-A, NFC-B, NFC-F, and other polling signals. Specific details can be found in related technologies, and this application does not impose limitations on these aspects. During the listening period, the near-field communication component can listen for external feedback signals to the transmitted polling signals. If a feedback signal is received, it indicates that the card has been read.

[0062] refer to Figure 1 and Figure 2 It can be seen that in each polling cycle of the near-field communication component, if the signal transmission period of the near-field communication component cannot completely fall within the image holding period of the display component, the signal transmission period will overlap with the image refresh period, thus affecting the normal display of the display component. Based on this, embodiments of this application provide a control method, control component, and display device for a display device, which can solve this problem.

[0063] like Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. The display device 10 may have a light-emitting surface a1, which can display images.

[0064] Please refer to Figure 4 as well as Figure 5 , Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the display device (section AA). Figure 5 yes Figure 4 The diagram shows a partial (area q indicated by the dashed box) enlarged structural diagram of the display device.

[0065] The display device includes a display component 11 and a near-field communication component.

[0066] The display component 11 includes a display substrate 111 and a heat dissipation layer 112 located on the back of the display substrate 111.

[0067] The near-field communication component includes a first controller ( Figure 4 and Figure 5 (not shown in the image) and coils ( Figure 4 and Figure 5(Not shown in the image), the first controller is electrically connected to the coil, which is located in the heat dissipation layer 112.

[0068] In addition, the display assembly 11 may also include other structures for realizing the display function, such as a transparent cover plate 113, ferrite 114, a flexible printed circuit (FPC) 115, a chip-on-film (COF) 116, and a display controller 117. The transparent cover plate 113 is located on the light-emitting surface of the display substrate 111 (the light-emitting surface is the side of the display substrate 111 where the image is displayed; the side opposite the light-emitting surface is the back surface of the display substrate 111) and is used to protect the display substrate 111. The ferrite 114 is located on the side of the heat dissipation layer 112 away from the display substrate 111 and is used to prevent various structures on the side of the ferrite 114 away from the display substrate 111 from affecting the coils in the near-field communication component. The flexible printed circuit board 115 is located on the side of the ferrite 114 away from the display substrate 111 and is used to carry various circuit devices. The COF 116 is connected to the portion of the display substrate 111 bent to the back surface and is also connected to the flexible printed circuit board 115. The display controller 117 is disposed on the flip-chip film 116.

[0069] Please refer to Figure 5 The display substrate 111 may include a buffer layer 1111, an organic light-emitting diode display panel 1112, a polarizing layer, a pressure-sensitive adhesive layer 1113, and an optical adhesive 1114, sequentially disposed on the side of the heat dissipation layer 112 away from the ferrite 114. The heat dissipation layer 112 may include a mesh adhesive layer 1121, foam 1122, pressure-sensitive adhesive 1123, a substrate 1124, and a metal layer 1125, sequentially disposed on the side of the ferrite 114 away from the flexible circuit board 115. The coil in the near-field communication component and the metal layer 1125 are of the same material and have the same layer structure. This simplifies the structure of the display device and saves on manufacturing processes.

[0070] For example, the material of the metal layer 1125 can be a metal with strong electrical and thermal conductivity, such as copper, aluminum, iron, or stainless steel. The metal layer 1125 and the coil in the near-field communication component can be formed by a single process (such as etching and laser cutting) and carried by ferrite.

[0071] The display device may also include a motherboard, on which the first control of the near-field communication component may be located and electrically connected to the coil via a flexible circuit board.

[0072] Please refer to Figure 6 , Figure 6 yes Figure 4 The diagram shown is a top view of the metal layer in the display device. (For clarity, this diagram is intended to illustrate the structure.) Figure 6The various structures above the metal layer are not shown. The coil 121 in the near-field communication component 12 is arranged around the metal layer 1125.

[0073] Optionally, the distance s between the coil 121 and the metal layer 1125 ranges from 1 mm to 50 mm. This avoids the metal layer 1125 from affecting the coil 121.

[0074] The display substrate contains data lines that can be arranged within it to achieve display functionality. In current display devices, to prevent the coil in the near-field communication (NFC) component from interfering with data transmission, the data lines and coil are typically designed to not overlap in a direction perpendicular to the first surface (the plane containing the light-emitting surface of the display substrate). This significantly impacts the coil's size. The method provided in this application solves this problem. Therefore, the orthographic projection of the NFC coil onto the first surface and the orthographic projection of the data line onto the first surface can at least partially overlap. This means that when setting the NFC coil, it is not necessary to deliberately avoid the data lines, allowing for a larger coil size and improving the NFC component's recognition distance.

[0075] Of course, in the display device provided in this application embodiment, the orthographic projection of the coil of the near-field communication component on the first surface and the orthographic projection of the data line on the first surface may not overlap, and this application embodiment does not impose any restrictions on this.

[0076] The display device also includes a control component, a near-field communication component, and a display component, all of which are electrically connected to the control component. The control component is used for:

[0077] Control the operation of the display components;

[0078] In response to a received first control command, control at least one of the near-field communication component and the display component to make the signal transmission period of the near-field communication component fall within the image holding period of the display component, wherein the near-field communication component is used to transmit a signal during the signal transmission period.

[0079] The display device may also include a motherboard, on which the control component may be located.

[0080] Optionally, the control component is also used for:

[0081] Send a first control signal to the near-field communication component and a second control signal to the display component;

[0082] The first control signal includes the target length of the signal transmission period, the target polling period, and the target position of the signal transmission period in each polling period. The target length is less than or equal to the length of the image holding period when the display component runs at the target refresh period. The target polling period is an integer multiple of the target refresh period. The target position is the same as the position of the image holding period in one refresh period of the display component. The second control signal is used to make the display component run at the target refresh period.

[0083] The control process of this control component can also be referred to in subsequent embodiments.

[0084] Please refer to Figure 7 , Figure 7 A schematic diagram of another display device provided in an embodiment of this application is shown. In this display device, the ferrite 114 is located on the side of the flexible circuit board 115 away from the display substrate 111, and the coil of the near-field communication component includes a first sub-coil 1211 and a second sub-coil 1212. The first sub-coil 1211 is located on the side of the flexible circuit board 115 closer to the display substrate 111, and the second sub-coil 1212 is located on the display substrate 111. This allows for a further increase in the size of the coil, thereby improving the recognition distance of the near-field communication component.

[0085] Figure 4 and Figure 7 Two display devices with front-facing near-field communication (NFC) capabilities are shown. These devices can perform NFC on the side displaying the image. They have a wide range of applications, such as those where NFC communication via the back of the display is inconvenient, like smartwatches and smart bracelets which typically require front-facing NFC.

[0086] However, such display devices may suffer from the problem of near-field communication components affecting the normal display of the display components. The control method for the display device provided in this application embodiment can solve this problem.

[0087] like Figure 8 As shown, Figure 8 This is a flowchart illustrating a control method for a display device according to an embodiment of this application. The method can be used in a display device, which can be the display device provided in the above embodiment. The method includes:

[0088] Step 801: Control the operation of the display component.

[0089] Step 802: In response to the received first control command, control at least one of the near-field communication component and the display component so that the signal transmission period of the near-field communication component is located within the image holding period of the display component, wherein the near-field communication component is used to transmit a signal during the signal transmission period.

[0090] In summary, the embodiments of this application provide a control method for a display device. This method controls at least one component of the near-field communication component and the display component during the display component's display phase, so that the signal transmission period of the near-field communication component is located within the image holding period of the display component. This avoids the overlap between the signal transmission period of the near-field communication component and the image refresh period of the display component, thereby preventing the near-field communication component from affecting the image refresh of the display component when transmitting signals. This solves the problem of poor display effect in related technologies and improves the display effect of the display device.

[0091] like Figure 9 As shown, Figure 9 This is a flowchart illustrating another control method for a display device provided in this application embodiment. This method can be used in a control component of a display device, which can be the display device provided in the above embodiment. The method includes:

[0092] Step 901: Control the operation of the display component.

[0093] In the method provided in this application embodiment, the control component can first control the display component to operate. For example, the control component can send a control signal to the display component to make the display component operate, and the display component can operate at a preset refresh rate, such as 30 Hz, 60 Hz, 120 Hz, 144 Hz, etc.

[0094] In one exemplary embodiment, the control component can control the display component to run while simultaneously controlling the process communication component to enter card mode. In card mode, the near-field communication component will not affect the normal display of the display component.

[0095] Step 902: In response to the received first control command, send a control signal to at least one of the near-field communication component and the display component.

[0096] The first control signal is used to make the polling period an integer multiple of the refresh period of the display component, and the signal transmission period is located in the image holding period of the display component. The polling period is the period during which the near-field communication component cyclically enters the signal transmission period and the listening period.

[0097] In one exemplary embodiment, a first control command may be used to instruct the near-field communication component to enter a card reader mode, wherein the near-field communication component is used to cycle through signal transmission periods and listening periods in the card reader mode.

[0098] Upon receiving the first control command, the control component can control the near-field communication component to enter the card reading mode, thereby cyclically entering the signal transmission period and the listening period, and sending control signals to at least one of the near-field communication component and the display component (that is, it can send control signals to the near-field communication component, send control signals to the display component, or send control signals to both the near-field communication component and the display component), so that the polling period is an integer multiple of the refresh period of the display component, and a certain signal transmission period is located in the image holding period of the display component, so that each signal transmission period in each polling cycle is located in the image holding period of the display component.

[0099] Of course, the first control command can also be a control command with other functions. For example, the first control command can be used to instruct the near-field communication component and the display component to synchronize so that the signal transmission period is within the image holding period of the display component. In this case, the near-field communication component can enter card reading mode before step 902, and upon receiving the first control command, it can begin to control the near-field communication component and the display component to synchronize.

[0100] When the near-field communication component is in card reading mode, if it reads information from an external card, it will change its operating state and enter information card reading mode to read the card information. In this mode, the near-field communication component will stop cycling between signal transmission period and listening period.

[0101] Step 903: In response to the card removal information received from the near-field communication component, control at least one of the near-field communication component and the display component to make the signal transmission period of the near-field communication component fall within the image holding period of the display component, wherein the card removal information is used to indicate that the card has been removed as read by the near-field communication component.

[0102] When the near-field communication component reads the card and the card is removed (card removal can mean that the read external card has moved beyond the maximum recognition distance of the near-field communication component), the control component can re-control the near-field communication component to enter the card reading mode, and control at least one of the near-field communication component and the display component so that the signal transmission period of the near-field communication component is located within the image holding period of the display component.

[0103] In steps 902 and 903 above, controlling at least one component of the near-field communication component and the display component to ensure that the signal transmission period of the near-field communication component is within the image holding period of the display component can include three implementations. The first implementation is to control the near-field communication component to achieve the effect of its signal transmission period being within the image holding period of the display component. The second implementation is to control the display component to achieve the effect of its signal transmission period being within the image holding period of the display component. The third implementation is to control both the display component and the near-field communication component to achieve the effect of its signal transmission period being within the image holding period of the display component. These three implementations will be described below:

[0104] In the first implementation: step 902 may include: sending a first control signal to the near-field communication component.

[0105] The first control signal includes the target length of the signal transmission period, the target polling period, and the target position of the signal transmission period in each polling period. The target length is less than or equal to the length of the current image holding period of the display component, the target polling period is an integer multiple of the current refresh period of the display component, and the target position is the same as the position of the image holding period in one refresh period of the display component.

[0106] The length of the image refresh period of the display component can be a characteristic of the display component itself, which can be determined before leaving the factory. The length of the image hold period can be related to the refresh cycle or refresh frequency of the display component. When the length of the refresh cycle of the display component is determined, the length of the image hold period (the length of the refresh cycle minus the length of the image refresh period is the length of the image hold period) will also be determined. For example, the longer the refresh cycle of the display component, the longer the image hold period will be. The current refresh cycle of the display component can be a fixed value at the factory or a variable value. For example, the refresh cycle of the display component can be a fixed 1 / 60 second, or it can vary between 1 / 30 second, 1 / 60 second, and 1 / 120 second under the control of the control component. Since the refresh frequency of the display component does not need to be adjusted in the first embodiment, the display component can operate at a higher refresh frequency (such as 60 Hz or higher).

[0107] In the first embodiment, it is possible to adjust only the near-field communication component without adjusting the display component (e.g., adjusting the refresh cycle). For example, the length of the signal transmission period can be adjusted so that the length of the signal transmission period is less than or equal to the length of the image holding period, and the position and period of the signal transmission period can be adjusted so that the signal transmission period in each polling cycle is located within the image holding period.

[0108] It should be noted that, in this embodiment, the position of the signal transmission period is used to indicate the position of the signal transmission period within a certain polling cycle, so that the signal transmission period can be located within the image hold period of a certain refresh cycle of the display component (which can be any refresh cycle after the current time, such as the refresh cycle closest to the current time). The position of the signal transmission period can be indicated by various information, such as the start time, middle time, or end time of the signal transmission period. For example, when the position of the signal transmission period is the start time of the signal transmission period, the start time can be the same as the start time of the image hold period in a certain refresh cycle of the display component.

[0109] In a second implementation, step 902 may include sending a second control signal to the display component.

[0110] The second control signal is used to cause the display component to operate at a target refresh rate, so that the signal transmission period falls within the image holding period of the display component. Since the signal transmission period of the near-field communication component is typically long, the target refresh rate may be greater than the preset refresh rate of the display component (this preset refresh rate may be the default refresh rate of the display component or a user-defined refresh rate), so that the length of the image holding period of the display component is greater than or equal to the signal transmission period. In other words, this implementation reduces the refresh rate of the display component.

[0111] For example, if the preset refresh period of the display component is 1 / 60 second, the length of the image holding period is the last 4 / 300 seconds of 1 / 60 second, and the length of the signal transmission period of the near-field communication component is 10 / 300 seconds, then the control component can increase the length of the image holding period to greater than or equal to 10 / 300 seconds based on the second control signal, and correspondingly increase the refresh period to the target refresh period, for example, the target refresh period can be 1 / 50 second.

[0112] Furthermore, the second control signal may only include the length of the signal transmission period. The display component can determine the target refresh period based on the length of the signal transmission period, so that the length of the image holding period is greater than or equal to the signal transmission period. Additionally, if the near-field communication component has not yet entered card reading mode at the current moment, the control component can send a control signal to the near-field communication component to cause it to enter card reading mode.

[0113] It should be noted that since simply increasing the length of the image hold period will reduce the refresh rate of the display component and affect the display effect, the control component can also reduce or eliminate the impact of increasing the length of the image hold period on the refresh rate of the display component by shortening the length of the image refresh period and increasing the length of the image hold period.

[0114] In the display device to which the method provided in this application is applied, the display component may include a low-temperature polycrystalline oxide (LTPO) display panel. This type of display panel can avoid screen flickering at low frame rates. Of course, the display component may also include other types of display panels, such as low-temperature polycrystalline silicon (LTPS) display panels, etc., and this application does not limit this.

[0115] In a third implementation, step 902 may include: sending a first control signal to the near-field communication component and sending a second control signal to the display component.

[0116] The first control signal includes the target length of the signal transmission period, the target polling period, and the target position of the signal transmission period in each polling period. The target length is less than or equal to the length of the image holding period when the display component runs at the target refresh period. The target polling period is an integer multiple of the target refresh period. The target position is the same as the position of the image holding period in one refresh period of the display component. The second control signal is used to make the display component run at the target refresh period.

[0117] In this implementation, both the display component and the near-field communication component are adjusted. This avoids the problem of poor performance caused by excessive adjustment to a single component. For example, it avoids the issue of poor display quality caused by drastically reducing the refresh rate of the display component.

[0118] This implementation method can be referred to. Figure 10 , Figure 10 This is a schematic diagram of one embodiment of the control method for a display device provided in this application. The control component can send a first control command to a near-field communication component and a second control command to a display component. Specifically, it can send the first control command to a first controller of the near-field communication component and the second control command to a display controller of the display component.

[0119] The display component can begin time alignment with the near-field communication (NFC) component. After time alignment, the NFC component can enter card reader mode, and the display component can operate at the target refresh rate. Time alignment here means ensuring that the signal transmission period of the NFC component falls within the image holding period of the display component. For example, the display component can begin adjusting the refresh rate length, and the NFC component can begin adjusting the polling period.

[0120] Once time alignment is complete, the display component can operate at the target refresh cycle. For the near-field communication component, when the card is detected, it can begin reading the card's information. While reading the card's information, it may affect the normal display of the display component. However, since the reading time is short and the user usually does not view the image displayed by the display component during the card reading process, it will not affect the user experience.

[0121] After the card is removed, the near-field communication component will receive the card removal information and send it to the control component. The control component can then re-control the near-field communication component and the display component to re-align the time.

[0122] The second and third embodiments described above adjust the refresh cycle of the display component, which may cause the display component to operate at a lower refresh rate. To improve the display effect, the control method for the display device in the second and third embodiments may further include:

[0123] In response to the received second control command, the near-field communication component is controlled to stop entering the signal transmission period, and the display component is controlled to operate at a first refresh cycle, which is less than the target refresh cycle.

[0124] The second control command can be used to instruct the near-field communication component to exit card reading mode and stop sending signals. The display component can then operate at the first refresh cycle, increasing the refresh rate and thus improving the display effect. After exiting card reading mode, the near-field communication component can enter card emulation mode, or it can stop operating altogether.

[0125] For example, with a target refresh cycle of 1 / 30 of a second, after the near-field communication component exits the card reading mode, the display component can operate at a first refresh cycle of 1 / 60 of a second, thereby increasing the refresh rate from 30 Hz to 60 Hz, which greatly improves the display effect.

[0126] In summary, the second and third implementation methods described above adjust the refresh cycle of the display component to ensure it operates at a target refresh cycle. Since the signal transmission period of the near-field communication (NFC) component is typically long, the display component's image retention period needs to be longer than or equal to the signal transmission period to increase the refresh cycle and consequently decrease the refresh frequency, resulting in a reduced display quality. Therefore, upon receiving the second control command, the NFC component can be controlled to exit card reading mode, and the display component can be controlled to operate at a first refresh cycle shorter than the target refresh cycle to increase the refresh frequency and improve the display quality.

[0127] In an exemplary embodiment, the signal transmission period of the near-field communication component is 100 microseconds; the refresh cycle of the display component is 16.67 milliseconds; and the listening period of the near-field communication component is 300 to 500 milliseconds. The control component can then begin time alignment to ensure that the length of the signal transmission period of the near-field communication component is less than or equal to the image holding period of the display component. The control component adjusts the signal transmission period T1 and the listening period T2 of the near-field communication component so that (T1+T2) / 16.67 is an integer. This ensures that each signal transmission period T1 falls within the image holding period.

[0128] like Figure 11 As shown, Figure 11 This is a schematic diagram of the operation after the display component and the near-field communication component are aligned. The length of the polling period N1 of the near-field communication component is twice the length of the refresh period F1 of the display component, and in each polling period, the signal transmission period completely coincides with the image holding period (e.g., F11 completely coincides with P1).

[0129] In summary, the embodiments of this application provide a control method for a display device. This method controls at least one component of the near-field communication component and the display component during the display component's display phase, so that the signal transmission period of the near-field communication component is located within the image holding period of the display component. This avoids the overlap between the signal transmission period of the near-field communication component and the image refresh period of the display component, thereby preventing the near-field communication component from affecting the image refresh of the display component when transmitting signals. This solves the problem of poor display effect in related technologies and improves the display effect of the display device.

[0130] This application embodiment also provides a control component for a display device, used in a display device including a near-field communication component and a display component, the control component of the display device including:

[0131] The first control module is used to control the operation of the display components.

[0132] The second control module is configured to control at least one of the near-field communication component and the display component in response to a received first control command, such that the signal transmission period of the near-field communication component is located within the image holding period of the display component, and the near-field communication component is configured to transmit a signal during the signal transmission period.

[0133] In summary, the embodiments of this application provide a control component for a display device. This control component controls at least one component of the near-field communication component and the display component during the display component's display time, so that the signal transmission period of the near-field communication component is located within the image holding period of the display component. This avoids the overlap between the signal transmission period of the near-field communication component and the image refresh period of the display component, thereby preventing the near-field communication component from affecting the image refresh of the display component when transmitting signals. This solves the problem of poor display effect in related technologies and improves the display effect of the display device.
