[0039] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0040] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0041] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0042] When using expressions such as "at least one of A, B, and C", they should generally be interpreted in accordance with the meaning that is commonly understood by a person skilled in the art (e.g., "a system having at least one of A, B, and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B, and C, etc.).

[0043] Embodiments of this disclosure provide a display driving method that can drive a display panel to switch between three modes: shared mode, dual-view mode, and privacy mode. This allows the display panel to not only fulfill the conventional wide-viewing-angle display function but also display different images to different viewing fields, or prevent one viewing field from receiving images from another, thereby improving the user experience of the display panel. The display driving method includes: determining a target viewing field from a plurality of viewing fields provided by the display panel, wherein the plurality of viewing fields includes a first viewing field facing a first region and a second viewing field facing a second region, the first region and the second region having no overlapping area or partial overlapping area; acquiring an image to be displayed for the target viewing field; and driving the display panel to display the image to be displayed for the target viewing field.

[0044] Figure 1 schematically illustrates a flowchart of a display driving method according to an embodiment of the present disclosure.

[0045] As shown in Figure 1, the method includes operations S110 to S130.

[0046] In operation S110, the target field of view is determined from multiple fields of view available from the display panel.

[0047] In operation S120, the screen to be displayed for the target field of view is acquired.

[0048] When operating S130, the drive display panel displays the image to be displayed in the target field of view.

[0049] The display panel can include devices used for displaying images in various electronic devices. These electronic devices may include, but are not limited to, mobile phones, monitors, and smart home appliances. For example, the display panel may include the screen portion of a mobile phone, the screen portion of a monitor, etc.

[0050] The display panel can consist of a display portion and a non-display portion. The display portion can include at least a pixel array, which can display the image frame by frame based on scan signals, data signals, etc. The non-display portion can include at least circuitry and devices that assist the pixel array in displaying the image.

[0051] Multiple fields of view may include a first field of view facing a first region and a second field of view facing a second region. Each field of view can be represented as a viewing angle range. For example, if the display panel can provide a viewing angle range of -80° to 80° in the horizontal direction, then the first field of view can represent a viewing angle range of -80° to 0°, and the second field of view can represent a viewing angle range of 0° to 80°.

[0052] The first or second region can be defined as the area within which the corresponding field of view displayed on the display panel can be seen from the corresponding viewing angle. There may be no overlap between the first and second regions, or there may be only partial overlap. That is, the field of view provided by the first region may not overlap with the field of view provided by the second region at all, or there may be only partial overlap; this is not limited here.

[0053] For the display panel, the image data of the screen to be displayed on the display panel can be stored in the memory of the display panel, and correspondingly, the screen to be displayed for the target field of view can be retrieved from the memory of the display panel.

[0054] The target field of view may include one field of view, that is, it can be any one of the first field of view and the second field of view; or, the target field of view may include multiple fields of view, that is, it can include the first field of view and the second field of view. Accordingly, the acquired display image for the target field of view may include only the image for the first field of view, or it may include the image for the second field of view, or it may include both the image for the first field of view and the image for the second field of view.

[0055] The display panel may include a pixel array, which can be connected to multiple data lines. Each data line can connect to a column of pixel units in the pixel array and provide a data signal to that column of pixel units. When driving the display panel to display an image to be displayed in a target field of view, the data signal of the display panel can be provided to at least a portion of the pixel unit columns of the pixel array through at least a portion of the multiple data lines, so that the image to be displayed can be displayed based on the target field of view of the display panel within one frame.

[0056] According to embodiments of this disclosure, when the display panel needs to switch the display field of view or change the displayed image, the target field of view can be determined from the multiple fields of view provided by the display panel, and the display panel can be driven to display the image to be displayed for the target field of view. This can meet the needs of different users to obtain different content through the same display panel, thereby effectively improving the user experience of the display panel.

[0057] Operations S110 to S130 as described above can be applied to a display device equipped with the display panel. The display device can execute operations S110 to S130 when the image displayed on the display panel changes. Changes in the image displayed on the display panel may include changes in the resolution of images displayed in one or more viewing areas, changes in the field of view for image display on the display panel, changes in the image to be displayed due to the access of an external device, etc., and are not limited thereto.

[0058] In one embodiment of this disclosure, a change in the image displayed on the display panel may include a change in the field of view of the display panel displaying the image. Examples of a change in the field of view of the image display may include changing from displaying only for a first field of view to displaying for both a first field of view and a second field of view simultaneously, changing from displaying for both a first field of view and a second field of view simultaneously to displaying only for the first field of view, changing from displaying for both a first field of view and a second field of view simultaneously to displaying only for the second field of view, and so on.

[0059] Optionally, the field of view provided by the display panel may further include a third field of view facing a third region, which overlaps with both the first and second regions. That is, the viewing angle range represented by the third field of view may be greater than that represented by both the first and second fields of view, and the viewing angle range represented by the third field of view may at least partially overlap with both the first and second fields of view. For example, if the viewing angle range represented by the first field of view is -80° to 0°, and the viewing angle range represented by the second field of view is 0° to 80°, then the viewing angle range represented by the third field of view may be -75° to 75°. Alternatively, the third region may include both the first and second regions. That is, the viewing angle range represented by the third field of view may be greater than the intersection of the viewing angle range represented by the first and second fields of view. For example, if the viewing angle range represented by the first field of view is -80° to 5°, and the viewing angle range represented by the second field of view is 5° to 80°, then the viewing angle range represented by the third field of view may be -80° to 80°.

[0060] In cases where the field of view provided by the display panel may also include a third field of view, examples of changes in the field of view for displaying the image may include changing from displaying only for the first field of view to displaying for the third field of view, changing from displaying for the third field of view to displaying for both the first and second fields of view simultaneously, and so on.

[0061] In the above examples of field-of-view changes, the conditions that trigger the field-of-view change are not limited. For example, the field of view can be changed based on the operator's operational instructions. As another example, the field of view can be changed adaptively based on the assessment of the states of multiple regions corresponding to multiple fields of view.

[0062] In one example, sensors, cameras, or other sensing devices can be installed in the first, second, or third area. These sensing devices can be used to collect data from multiple areas. By analyzing the collected data, a judgment can be made as to whether it is still necessary to display the image for a certain field of view. Based on this result, the field of view can be changed.

[0063] Optionally, the determination result can be represented based on the respective presence status of the first and second regions. The presence status can include both present and absent. If the presence status of a certain region is "present," then the determination result can indicate that image display is still required for the field of view corresponding to that region; that is, the determined target field of view can include that region. Conversely, if the presence status of a certain region is "absent," then the determination result can indicate that image display is not required for the field of view corresponding to that region; that is, the determined target field of view does not include that region.

[0064] Taking an in-vehicle display scenario as an example, the first area can represent the driver's area, and the second area can represent the passenger's area. The presence status of the first area indicates whether there is someone in the driver's area. If the presence status of the first area indicates that someone is in the driver's area, the result is that someone is in the driver's area, and the display needs to be directed towards this first field of view. If the presence status of the first area indicates that someone is not in the driver's area, the result is that no one is in the driver's area, and the display does not need to be directed towards this first field of view. Similarly, the presence status of the second area indicates whether there is someone in the passenger's area. If the presence status of the second area indicates that someone is in the passenger's area, the result is that someone is in the passenger's area, and the display needs to be directed towards this second field of view. If the presence status of the second area indicates that someone is not in the passenger's area, the result is that no one is in the passenger's area, and the display does not need to be directed towards this second field of view.

[0065] Therefore, when determining the target field of view from multiple fields of view provided by the display panel, the target field of view can be determined from multiple fields of view based on the respective in-situ states of the first region and the second region.

[0066] Optionally, in some embodiments, the presence status of both the first region and the second region can be represented as "in place". When both the first and second regions are represented as "in place", the target field of view can be determined to include both the first and second fields of view. In this case, the display panel needs to display images for both the first and second fields of view simultaneously.

[0067] In embodiments of this disclosure, the screen to be displayed may include a first screen to be displayed for a first field of view and a second screen to be displayed for a second field of view. The pixel array of the display panel may include a plurality of pixel unit columns, which may include a plurality of first pixel unit columns for displaying the screen for the first field of view and a plurality of second pixel unit columns for displaying the screen for the second field of view.

[0068] When a display panel needs to display images simultaneously for a first field of view and a second field of view, multiple columns of first pixel units and multiple columns of second pixel units can be used to display the first image to be displayed and the second image to be displayed respectively, so that different images can be displayed for the first field of view and the second field of view. Specifically, the data signal of the first image to be displayed can be provided to multiple columns of first pixel units to drive the display panel to display the first image to be displayed for the first field of view, and the data signal of the second image to be displayed can be provided to multiple columns of second pixel units to drive the display panel to display the second image to be displayed for the second field of view.

[0069] Optionally, the first and second images to be displayed can be the same, meaning the display panel can project the same image into both the first and second fields of view. Alternatively, the image can be displayed through a third field of view. Specifically, the data signal of the image to be displayed can be provided to multiple pixel unit columns to drive the display panel to display the image in the third field of view.

[0070] Optionally, in some embodiments, the presence state of one of the first and second regions can be represented as "in place," and the presence state of the other region can be represented as "out of place." In this case, the field of view corresponding to the region whose presence state is represented as "in place" can be used as the target field of view.

[0071] For example, if the in-situ state of the first region is represented as "in-situ" and the in-situ state of the second region is represented as "out-of-situ", the target field of view can be determined as the first field of view. If the in-situ state of the first region is represented as "out-of-situ" and the in-situ state of the second region is represented as "in-situ", the target field of view can be determined as the second field of view.

[0072] When displaying the image to be displayed in the first field of view, the data signal of the image to be displayed can be provided to multiple columns of first pixel units to drive the display panel to display the image to be displayed in the first field of view.

[0073] When displaying the image to be displayed in the second field of view, the data signal of the image to be displayed can be provided to multiple columns of second pixel units to drive the display panel to display the image to be displayed in the second field of view.

[0074] Figure 2 schematically illustrates a flowchart of a display driving method according to another embodiment of the present disclosure.

[0075] As shown in Figure 2, the method may include operations S201 to S208.

[0076] In operation S201, the in-situ status of the first region and the second region is obtained.

[0077] In operation S202, it is determined whether the in-position state of the first region is indicated as "in-position". If it is determined that the in-position state of the first region is indicated as "in-position", operation S203 is executed. If it is determined that the in-position state of the first region is indicated as "out-of-position", operation S206 is executed.

[0078] In operation S203, it is determined whether the in-position state of the second region is indicated as "in-position". If it is determined that the in-position state of the second region is indicated as "in-position", operation S204 is executed. If it is determined that the in-position state of the second region is indicated as "out-of-position", operation S205 is executed.

[0079] In operation S204, the drive display panel displays the first image to be displayed for the first field of view and the second image to be displayed for the second field of view.

[0080] When operating S205, the drive display panel displays the image to be displayed for the first field of view.

[0081] In operation S206, it is determined whether the in-position state of the second region is indicated as "in-position". If it is determined that the in-position state of the second region is indicated as "in-position", operation S207 is executed. If it is determined that the in-position state of the second region is indicated as "out-of-position", operation S208 is executed.

[0082] When operating S207, the drive display panel displays the image to be displayed for the second field of view.

[0083] When operating S208, turn off the display panel or control the display panel to enter sleep mode.

[0084] According to embodiments of this disclosure, when displaying only one of the first and second fields of view, the data signal of the image to be displayed can be provided only to the pixel unit column of the corresponding field of view. At this time, only some pixel unit columns of the display panel are in working state, thus effectively reducing the power consumption of the display panel.

[0085] Optionally, in scenarios where power consumption is not critical, or where high resolution is required for the displayed image, even if only one of the first and second regions is present, the field of view corresponding to that present region can be selected as the target field of view, or a third field of view can be selected. That is, when the presence status of the first region is indicated as "present" and the presence status of the second region is indicated as "absent," either the first or third field of view can be selected as the target field of view. Conversely, when the presence status of the first region is indicated as "absent" and the presence status of the second region is indicated as "present," either the second or third field of view can be selected as the target field of view.

[0086] The target field of view can be determined from the field of view corresponding to the in-situ region and the third field of view based on various strategies. For example, it can be selected based on the power consumption mode of the display panel. If the power consumption mode of the display panel is in power saving mode, the field of view corresponding to the in-situ region can be selected as the target field of view. If the power consumption mode of the display panel is in a mode other than power saving mode, the third field of view can be selected as the target field of view. No limitation is made here.

[0087] When displaying the image to be displayed in the third field of view, the data signal of the image to be displayed can be provided to multiple pixel unit columns to drive the display panel to display the image to be displayed in the third field of view.

[0088] Figure 3 schematically illustrates a flowchart of a display driving method according to another embodiment of the present disclosure.

[0089] As shown in Figure 3, the method may include operations S301 to S312.

[0090] In operation S301, the in-situ status of the first region and the second region is obtained.

[0091] In operation S302, it is determined whether the in-position state of the first region is indicated as "in-position". If it is determined that the in-position state of the first region is indicated as "in-position", operation S303 is executed. If it is determined that the in-position state of the first region is indicated as "out-of-position", operation S308 is executed.

[0092] In operation S303, it is determined whether the in-position state of the second region is indicated as "in-position". If it is determined that the in-position state of the second region is indicated as "in-position", operation S304 is executed. If it is determined that the in-position state of the second region is indicated as "out-of-position", operation S305 is executed.

[0093] When operating S304, the drive display panel displays the first image to be displayed for the first field of view and the second image to be displayed for the second field of view.

[0094] In operation S305, determine whether the display panel's power consumption mode is power saving mode. If it is determined that the display panel's power consumption mode is power saving mode, proceed to operation S306. If it is determined that the display panel's power consumption mode is not power saving mode, proceed to operation S307.

[0095] When operating S306, the drive display panel displays the image to be displayed for the first field of view.

[0096] When operating S307, drive the display panel to display the image to be displayed for the third field of view.

[0097] In operation S308, it is determined whether the in-position state of the second region is indicated as "in-position". If it is determined that the in-position state of the second region is indicated as "in-position", operation S309 is executed. If it is determined that the in-position state of the second region is indicated as "out-of-position", operation S312 is executed.

[0098] In operation S309, determine whether the power consumption mode of the display panel is in power saving mode. If it is determined that the power consumption mode of the display panel is in power saving mode, execute operation S310. If it is determined that the power consumption mode of the display panel is not in power saving mode, execute operation S311.

[0099] When operating the S310, the drive display panel displays the image to be displayed for the second field of view.

[0100] When operating S311, the drive display panel displays the image to be displayed for the third field of view.

[0101] When operating S312, turn off the display panel or control the display panel to enter sleep mode.

[0102] Optionally, the display panel may include multiple display modes, such as shared mode, dual-view mode, and privacy mode. Using the display driving method described above, the display panel can be controlled to switch between shared mode, dual-view mode, and privacy mode.

[0103] For example, when it is necessary to control the display panel to switch to shared mode, the display panel can be driven to display the image for the third field of view. The displayed image can be the image originally displayed for the first field of view or the image originally displayed for the second field of view.

[0104] For example, when it is necessary to control the display panel to switch to dual-view mode, the display panel can be driven to display the first image for the first field of view and the second image for the second field of view.

[0105] For example, when it is necessary to control the display panel to switch to privacy mode, the display panel can be driven to display a normal image for one of the first and second viewing fields, and not display an image for the other viewing field, or display a default image for the other viewing field. The default image can be an image designed for privacy, for example, the default image can be a solid color image with a black color.

[0106] In the above embodiments, the resolution allocated by the display panel to the first and second fields of view can be fixed. For example, the number of first pixel unit columns and the number of second pixel unit columns in the pixel array of the display panel can be equal, then the resolution of the image displayed in the first field of view and the image displayed in the second field of view are both fixed at half the rated resolution of the display panel. Alternatively, for another example, the ratio between the number of first pixel unit columns and the number of second pixel unit columns in the pixel array of the display panel can be m:n, then the ratio between the resolution of the image displayed in the first field of view and the resolution of the image displayed in the second field of view can be m:n.

[0107] Optionally, in another embodiment of this disclosure, the change in the image displayed on the display panel may further include a change in the resolution of the image displayed for one or more viewing areas.

[0108] For example, if the field of view targeted by the display panel remains unchanged, or if the display panel only displays the image for one field of view after the field of view changes, the display panel can be driven to display the image for that field of view based on the resolution of the image to be displayed.

[0109] In one example, the target field of view can be a first field of view. The acquired display screen for the target field of view can include: acquiring a first display screen for the first field of view.

[0110] At this point, a first resolution for the first field of view can be determined based on the first image to be displayed. This first resolution can be less than or equal to the rated resolution of the display panel. Optionally, if the resolution of the first image to be displayed is less than the rated resolution, the first resolution can be equal to the resolution of the first image to be displayed. If the resolution of the first image to be displayed is greater than or equal to the rated resolution, the first resolution can be set to be equal to the rated resolution.

[0111] When driving the display panel to display an image, the display panel can be driven to display the first image to be displayed for the first field of view based on the first resolution.

[0112] Specifically, based on the first resolution, multiple first pixel unit columns for displaying the image for the first field of view can be determined from the multiple pixel unit columns included in the pixel array of the display panel, and the data signal of the first image to be displayed can be provided to the multiple first pixel unit columns to drive the display panel to display the first image to be displayed for the first field of view.

[0113] For a first field of view, when the resolution of the image to be displayed changes, the number and distribution of pixel unit columns used for displaying the image in the first field of view will also change accordingly. For example, if the resolution of the previous frame of the first image to be displayed is m1*k, when the display panel displays the previous frame for the first field of view, m1 pixel unit columns are selected from multiple pixel unit columns of the display panel, and the data signal of the previous frame is provided to these m1 pixel unit columns to drive the display panel to display the image with a resolution of m1*k for the first field of view. If the resolution of the first image to be displayed can be m2*k, then in the current frame, m2 pixel unit columns need to be selected from multiple pixel unit columns of the display panel, and the data signal of the first image to be displayed is provided to these m2 pixel unit columns to drive the display panel to display the image with a resolution of m2*k for the first field of view. K can represent the number of pixel units contained in each pixel unit column.

[0114] In another example, the target field of view can be a second field of view. The acquired display screen for the target field of view can include: acquiring a second display screen for the second field of view.

[0115] At this point, a second resolution for the second field of view can be determined based on the second image to be displayed. This second resolution can be less than or equal to the rated resolution of the display panel. Optionally, if the resolution of the second image to be displayed is less than the rated resolution, the second resolution can be equal to the resolution of the second image to be displayed. If the resolution of the second image to be displayed is greater than or equal to the rated resolution, the second resolution can be set to be equal to the rated resolution.

[0116] When driving the display panel to display an image, the second display panel can be driven to display a second image to be displayed for a second field of view based on the second resolution.

[0117] Specifically, based on the second resolution, multiple second pixel unit columns for displaying the image for the second field of view can be determined from the multiple pixel unit columns included in the pixel array of the display panel, and the data signal of the second image to be displayed can be provided to the multiple second pixel unit columns to drive the display panel to display the second image to be displayed for the second field of view.

[0118] For the second field of view, when the resolution of the image to be displayed changes, the number and distribution of pixel unit columns used for displaying the image in the first field of view will also change accordingly. For example, if the resolution of the previous frame of the second image to be displayed is m3*k, when the display panel displays the previous frame for the second field of view, m3 pixel unit columns are selected from multiple pixel unit columns of the display panel, and the data signal of the previous frame is provided to these m3 pixel unit columns to drive the display panel to display the image with a resolution of m3*k for the second field of view. If the resolution of the second image to be displayed can be m4*k, then in the current frame, m4 pixel unit columns need to be selected from multiple pixel unit columns of the display panel, and the data signal of the second image to be displayed is provided to these m4 pixel unit columns to drive the display panel to display the image with a resolution of m4*k for the second field of view.

[0119] Alternatively, in another example, the target field of view can be a third field of view. In this case, the third resolution of the third field of view can be determined based on the rated resolution of the display panel and the resolution of the image to be displayed. For example, if the resolution of the image to be displayed is less than the rated resolution, the resolution of the image to be displayed can be selected as the third resolution, or the rated resolution can be directly used as the third resolution. If the resolution of the image to be displayed is greater than or equal to the rated resolution, the rated resolution can be used as the third resolution.

[0120] When the third resolution is the rated resolution, the data signal of the image to be displayed can be provided to multiple pixel unit columns to drive the display panel to display the image to be displayed in the third field of view. When the third resolution is the resolution of the image to be displayed, multiple third pixel unit columns can be selected from multiple pixel unit columns based on the resolution of the image to be displayed, and the data signal of the image to be displayed can be provided to the multiple third pixel unit columns to drive the display panel to display the image to be displayed in the third field of view.

[0121] For example, when the display panel displays images for both a first field of view and a second field of view simultaneously, the resolution can be allocated based on the resolution of the image displayed in the first field of view and the resolution of the image displayed in the second field of view.

[0122] In this example, the target field of view may include a first field of view and a second field of view, and obtaining the screen to be displayed for the target field of view may include obtaining a first screen to be displayed for the first field of view and obtaining a second screen to be displayed for the second field of view.

[0123] Based on the resolution of the first and second images to be displayed, a resolution allocation ratio can be obtained. Based on the resolution allocation ratio, the rated resolution of the display panel can be allocated to determine the first resolution allocated to the first field of view and the second resolution allocated to the second field of view. The first and second resolutions are less than the rated resolution of the display panel.

[0124] Resolution allocation ratio refers to the horizontal resolution allocation ratio. When allocating resolution, the first and second display screens can be scaled to match the vertical resolution. The resolution allocation ratio is then determined based on these scaled screens. For example, if the resolution of the first display screen is n1*2*k and the resolution of the second display screen is n2*k, the second display screen can be scaled to obtain a scaled second display screen with a resolution of (2*n2)*2*k. Therefore, the resolution allocation ratio between the first and second fields of view can be n1:(2*n2). If the rated resolution of the display panel is N*K, then after resolution allocation, the first resolution can be (n1*N / (n1+2*n2))*K, and the second resolution can be (2*n2*N / (n1+2*n2))*K.

[0125] After determining the first resolution and the second resolution, the display panel can be driven to display a first image to be displayed for a first field of view and a second image to be displayed for a second field of view, based on the first resolution and the second resolution, respectively. Specifically, based on the resolution allocation ratio, multiple pixel unit columns can be divided into multiple first pixel unit columns and multiple second pixel unit columns, and then the multiple first pixel unit columns and multiple second pixel unit columns can be driven to display the first image to be displayed and the second image to be displayed, respectively. For example, the first resolution can be (n1*N / (n1+2*n2))*K, the second resolution can be (2*n2*N / (n1+2*n2))*K, the resolution allocation ratio can be n1:(2*n2), and the display panel includes N pixel unit columns, then the number of first pixel unit columns is n1*N / (n1+2*n2), and the number of second pixel unit columns is 2*n2*N / (n1+2*n2). The data signal of the first image to be displayed can be provided to n1*N / (n1+2*n2) first pixel unit columns respectively, so as to drive the n1*N / (n1+2*n2) first pixel unit columns to display the first image to be displayed in the first field of view. At the same time, the data signal of the second image to be displayed can be provided to 2*n2*N / (n1+2*n2) second pixel unit columns respectively, so as to drive the 2*n2*N / (n1+2*n2) second pixel unit columns to display the second image to be displayed in the second field of view.

[0126] Figure 4 schematically illustrates a flowchart of a display driving method according to another embodiment of the present disclosure.

[0127] As shown in Figure 4, the method includes operations S401 to S412.

[0128] In operation S401, a target field of view is determined from multiple fields of view. If the target field of view includes a first field of view and / or a second field of view, operation S402 is performed. If the target field of view is a third field of view, operation S410 is performed.

[0129] In operation S402, a first displayable image for a first field of view and / or a second displayable image for a second field of view are acquired. If the target field of view is the first field of view, operation S403 is performed. If the target field of view is the second field of view, operation S405 is performed. If the target field of view includes both the first and second fields of view, operation S407 is performed.

[0130] In operation S403, a first resolution is determined based on the first screen to be displayed.

[0131] When operating S404, based on the first resolution, the drive display panel displays the first image to be displayed for the first field of view.

[0132] In operation S405, a second resolution is determined based on the second screen to be displayed.

[0133] When operating S406, based on the second resolution, the drive display panel displays the second image to be displayed for the second field of view.

[0134] In operation S407, the resolution allocation ratio is obtained based on the first screen to be displayed and the second screen to be displayed.

[0135] In operation S408, the first resolution and the second resolution are obtained based on the resolution allocation ratio.

[0136] In operation of S409, based on the first resolution, the display panel is driven to display the first image to be displayed in the first field of view, and based on the second resolution, the display panel is driven to display the second image to be displayed in the second field of view.

[0137] In operation S410, the screen to be displayed for the third field of view is acquired.

[0138] When operating S411, a third resolution is obtained based on the rated resolution of the display panel and the resolution of the image to be displayed.

[0139] When operating the S412, based on the third resolution, the drive display panel displays the image to be displayed for the third field of view.

[0140] Optionally, in addition to allocating the resolution of the first and second fields of view based on the resolution of the images to be displayed in each field of view, the resolution of the first and second fields of view can also be freely adjusted based on the operator's instructions, which will not be elaborated here.

[0141] According to embodiments of this disclosure, when driving the display panel to display an image, the resolution of each field of view can be adaptively adjusted according to the needs or the resolution of the image to be displayed, so that the display panel can simultaneously meet the viewing and entertainment needs of multiple people, thereby effectively improving the user experience of the display panel.

[0142] Optionally, the image displayed on the display panel can be the image of an application running on the display device. For example, a first field of view can be used to display the image of a first application, and a second field of view can be used to display the image of a second application. The first application and the second application can be the same application, in which case the first field of view and the second field of view can be used to display the same image. Alternatively, the second application and the second application can be different applications, in which case the image displayed in the first field of view is different from the image displayed in the second field of view.

[0143] The display device described above can be configured with a display control system, and the first application and the second application can run in the operating environment provided by the display control system. Alternatively, the display control system can run a first virtual system, and both the first application and the second application can run in the first virtual system. In this case, the first field of view can be associated with the first virtual system, and the second field of view can also be associated with the first virtual system.

[0144] The following example illustrates the timing of the application of a display driving method in a display device, using the example of both the first and second fields of view being associated with a first virtual system.

[0145] Figure 5A schematically illustrates the timing diagram of applying a display driving method in a display device according to an embodiment of the present disclosure.

[0146] As shown in Figure 5A, the display control system 510 can acquire the in-situ status of the first region 520 and the second region 530 respectively.

[0147] Sensors can be installed in both the first region 520 and the second region 530. At time t1, the sensor in the first region 520 can detect an presence signal, and at this time, the sensor can transmit information indicating that the first region is in place to the display control system 510. When the first virtual system is not running, the display control system 510 will generate and run the first virtual system. If the first virtual system is already running, the display control system 510 can control the first virtual system to run the first application and control the display panel 540 to display the screen of the first application for the first field of view. When displaying the screen of the first application, the display panel 540 can display the screen according to the rated resolution of the display panel, half of the rated resolution, or the resolution of the screen of the first application, etc., without limitation.

[0148] At time t2, the sensor at the second region 530 can detect an presence signal. At this time, the sensor can transmit information indicating the presence of the second region to the display control system 510. The display control system 510 can control the first virtual system to run the second application and control the display panel 540 to display the screen of the first application in the first field of view while simultaneously displaying the screen of the second application in the second field of view. The relationship between the resolution of the first field of view and the resolution of the second field of view can be adjusted in response to operator commands, or the resolution of the first field of view and the resolution of the second field of view can be determined based on the resolution of the screen of the first application and the resolution of the screen of the second application; this is not limited here. For example, in the example shown in Figure 5A, the ratio between the resolution of the first field of view and the resolution of the second field of view can be 1:1 between time t2 and time t3.

[0149] At time t3, the sensor at the second region 530 detects a displacement signal. At this time, the sensor can transmit information indicating that the second region has been displaced to the display control system 510. The display control system 510 can control the first virtual system to stop running the second application and control the display panel 540 to display the screen of the first application for the first field of view.

[0150] At time t4, the sensor at the second region 530 can detect the presence signal again. At this time, the sensor can transmit information indicating that the second region is in place to the display control system 510. The display control system 510 can control the first virtual system to start running the second application, and control the display panel 540 to display the screen of the first application in the first field of view, while simultaneously displaying the screen of the second application in the second field of view.

[0151] At time t5, the sensor at the first region 520 detects a displacement signal. At this time, the sensor can transmit information indicating that the first region has been displaced to the display control system 510. The display control system 510 can control the first virtual system to stop running the first application and control the display panel 540 to display the screen of the second application for the second field of view.

[0152] Taking an in-vehicle display scenario as an example, in the example shown in Figure 5A, the display control system can be represented as the vehicle's in-vehicle system, and the display device equipped with the display panel can be the vehicle's dual-view display screen. The first area can represent the driver's area, the presence status of the first area can indicate whether there is anyone in the driver's area, the first field of view can represent the driver's field of view, and the first application can represent the driver's application. The second area can represent the passenger's area, the presence status of the second area can indicate whether there is anyone in the passenger's area, the second field of view can represent the passenger's field of view, and the second application can represent the passenger's application.

[0153] After the vehicle is started, the in-vehicle system can receive registration requests from the dual-view display, the driver's seat sensor or door sensor, and the passenger seat sensor or door sensor. The in-vehicle system can subscribe to sensor data from the driver's seat sensor or door sensor, as well as the passenger seat sensor or door sensor.

[0154] The vehicle system can receive a driver presence event when someone is in the driver's area, the driver's seatbelt is engaged, or the vehicle is unlocked. The vehicle system can generate a virtual system that can run driver-specific applications. Optionally, the virtual system generation process may include the vehicle's processing chip first booting a virtualized operating system, and then generating the virtual system to be used as a real-time operating system. The vehicle system can control the dual-view display to show the driver's application feed at full resolution or half resolution from the driver's perspective.

[0155] When someone is in the passenger area or their seatbelt is fastened, the vehicle system can receive a passenger presence event, and the virtual system can run the passenger application. The vehicle system can control the dual-view display to show the driver's application at half resolution from the driver's perspective, and the passenger's application at half resolution from the passenger's perspective.

[0156] When the passenger area is unoccupied or the passenger's seatbelt is unfastened, the vehicle system can receive a passenger leaving the vehicle. The virtual system can then stop the passenger-side application from running and control the dual-view display to not show the image for the passenger's field of view. Furthermore, the vehicle system can control the dual-view display to show the driver's application's image for the driver's field of view at full resolution or half resolution.

[0157] Alternatively, if someone is in the passenger area or their seatbelt is fastened, but the driver's area is empty or their seatbelt is unfastened, the vehicle system can receive a driver departure event. The virtual system can then stop the driver's application from running. The vehicle system can control the dual-view display to not show the image from the driver's field of view. Furthermore, the vehicle system can control the dual-view display to show the passenger's application from the passenger's perspective at full resolution or half resolution.

[0158] Optionally, the resolution of each field of view can be adjusted based on the operator's instructions during the display process.

[0159] Figure 5B schematically illustrates the timing diagram of applying a display driving method in a display device according to another embodiment of the present disclosure.

[0160] As shown in Figure 5B, at time t1, both the sensor configured in the first region 520 and the sensor configured in the second region 530 can detect an presence signal. The sensor configured in the first region 520 can transmit information indicating the presence of the first region to the display control system 510, and the sensor configured in the second region 530 can transmit information indicating the presence of the second region to the display control system 510. The display control system 510 can generate a first virtual system and control the first virtual system to run a first application and a second application. Subsequently, the display control system 510 can control the display panel 540 to display the screen of the first application in a 1:1 resolution ratio, and display the screen of the second application in a first field of view and a second field of view, respectively.

[0161] At time t2, the operator in the second area 530 can control the first virtual system to move the third application via control commands, thereby controlling the display panel 540 to switch to displaying the third application's screen for the second field of view. Based on the resolution of the third application's screen and the resolution of the first application, the display control system 510 can control the display panel 540 to display the first application's screen for the first field of view and the third application's screen for the second field of view according to an m:n resolution allocation ratio.

[0162] Taking an in-vehicle display scenario as an example, in the example shown in Figure 5B, the display control system can be represented as the vehicle's in-vehicle system, and the display device equipped with the display panel can be the vehicle's dual-view display screen. The first area can represent the driver's area, the presence status of the first area can indicate whether there is someone in the driver's area, the first field of view can represent the driver's field of view, and the first application can represent the driver's application. The second area can represent the passenger's area, the presence status of the second area can indicate whether there is someone in the passenger's area, the second field of view can represent the passenger's field of view, and the second application can represent the passenger's application.

[0163] After the vehicle is started, the in-vehicle system can receive registration requests from the dual-view display, the driver's seat sensor or door sensor, and the passenger seat sensor or door sensor. The in-vehicle system can subscribe to sensor data from the driver's seat sensor or door sensor, as well as the passenger seat sensor or door sensor.

[0164] The vehicle system can receive a driver presence event when someone is in the driver's area, the driver's seatbelt is fastened, or the vehicle is unlocked. The system can then generate a virtual system that runs driver-specific applications. The system can control the dual-view display to show the driver's application feed at full resolution or half resolution from the driver's perspective.

[0165] When someone is in the passenger area or their seatbelt is fastened, the vehicle system can receive a passenger presence event, and the virtual system can run the passenger application. The vehicle system can control the dual-view display to show the driver's application at half resolution from the driver's perspective, and the passenger's application at half resolution from the passenger's perspective.

[0166] When an operator in the passenger seat area activates an entertainment application, the virtual system can request a resolution adjustment from the vehicle's in-vehicle system. The in-vehicle system can then adjust the display resolution ratio between the driver's and passenger's fields of view based on this request, and control the switching of resolution between the two fields of view, for example, switching the display resolution ratio to m:n. The in-vehicle system can then control the dual-view displays to show the driver's application's content in the driver's field of view and the entertainment application's content in the passenger's field of view, respectively, according to the m:n resolution ratio.

[0167] In some embodiments, to avoid crosstalk between applications providing images to different fields of view, the display control system may run multiple virtual systems, each of which may run an application associated with a field of view.

[0168] Optionally, the first field of view can be associated with the first virtual system, the second field of view can be associated with the second virtual system, and the first application and the second application can run on the first virtual system and the second virtual system, respectively.

[0169] At this point, when acquiring the image to be displayed for the target field of view, the target virtual system corresponding to the target field of view can be determined from the first virtual system and the second virtual system, and the image to be displayed can be obtained based on the image of the application running in the target virtual system. That is, when the target field of view is the first field of view, the image of the first application can be acquired from the first virtual system, and the image of the first application can be used as the image to be displayed. When the target field of view is the second field of view, the image of the second application can be acquired from the second virtual system, and the image of the second application can be used as the image to be displayed. When the target field of view includes both the first and second fields of view, the image of the first application can be acquired from the first virtual system, the image of the second application can be acquired from the second virtual system, and the images of the first and second applications can be used as the images to be displayed.

[0170] Figure 5C schematically illustrates the timing diagram of applying a display driving method in a display device according to another embodiment of the present disclosure.

[0171] As shown in Figure 5C, at time t1, the sensor at the first region 520 can detect an presence signal. At this time, the sensor can transmit information indicating the presence of the first region to the display control system 510. The display control system 510 can generate and run a first virtual system and control the first virtual system to run a first application. Subsequently, the display control system 510 can control the display panel 540 to display the screen of the first application for the first field of view.

[0172] At time t2, the sensor at the second region 530 can detect an presence signal. At this time, the sensor can transmit information indicating the presence of the second region to the display control system 510. The display control system 510 can generate and run a second virtual system and control the second virtual system to run a second application. Subsequently, the display control system 510 can control the display panel 540 to display the screen of the first application in the first field of view while simultaneously displaying the screen of the second application in the second field of view.

[0173] At time t3, the sensor at the second region 530 detects a displacement signal. At this time, the sensor can transmit information indicating that the second region is displaced to the display control system 510. The display control system 510 can freeze or stop the second virtual system and control the display panel 540 to display the screen of the first application for the first field of view.

[0174] Taking an in-vehicle display scenario as an example, in the example shown in Figure 5C, the display control system can be represented as the vehicle's in-vehicle system, and the display device equipped with the display panel can be the vehicle's dual-view display screen. The first area can represent the driver's area; the presence status of the first area can indicate whether there is someone in the driver's area; the first field of view can represent the driver's field of view; the first virtual system can represent the driver's virtual system; and the first application can represent the driver's application. The second area can represent the passenger's area; the presence status of the second area can indicate whether there is someone in the passenger's area; the second field of view can represent the passenger's field of view; the second virtual system can represent the passenger's virtual system; and the second application can represent the passenger's application.

[0175] After the vehicle is started, the in-vehicle system can receive registration requests from the dual-view display, the driver's seat sensor or door sensor, and the passenger seat sensor or door sensor. The in-vehicle system can subscribe to sensor data from the driver's seat sensor or door sensor, as well as the passenger seat sensor or door sensor.

[0176] The vehicle system can receive a driver presence event when someone is in the driver's area, the driver's seatbelt is fastened, or the vehicle is unlocked. The system can then generate a driver-centric virtual system, which can run driver-centric applications. The system can control the dual-view display to show the driver-centric application's view at full resolution or half resolution from the driver's perspective.

[0177] When someone is in the passenger area or their seatbelt is fastened, the vehicle system can receive a passenger presence event. The system can then generate a virtual passenger system, which can run passenger applications. The system can control the dual-view display to show the driver's application at half resolution from the driver's perspective, and also control the dual-view display to show the passenger's application at half resolution from the passenger's perspective.

[0178] When the passenger area is unoccupied or the passenger's seatbelt is unfastened, the vehicle system can receive a passenger leaving the vehicle. The system can then stop or freeze the passenger virtual system. Furthermore, the system can control the dual-view display to show the driver's application at full resolution or half resolution for the driver's field of view.

[0179] Similarly, during the display process, the resolution of each field of view can be adjusted based on operator commands. For example, in the example shown in Figure 5C, at a moment between time t2 and time t3, the operator located in the second area 530 can control the second virtual system to move the third application via control commands, thereby controlling the display panel 540 to switch to displaying the third application's image for the second field of view. Based on the resolution of the third application's image and the resolution of the first application, the display control system 510 can control the display panel 540 to display the first application's image for the first field of view and the third application's image for the second field of view according to an m:n resolution allocation ratio. Further details are omitted here.

[0180] For example, in the example shown in Figure 5C, the resolution of the dual-view display can be M*N. When both the driver's and passenger's viewpoints are displayed, after switching the resolution according to the m:n resolution allocation ratio, the vehicle system can control the dual-view display to display the driver's application screen at a resolution of (m*M / (m*n))*N for the driver's viewpoint, and control the dual-view display to display the passenger's application screen at a resolution of (n*M / (m*n))*N for the passenger's viewpoint.

[0181] In some embodiments, the display panel can also establish a communication connection with a mobile device and display the image provided by the mobile device for a target field of view. The protocol on which the communication connection is established may include Bluetooth communication protocol, wireless network protocol, etc., and is not limited thereto.

[0182] Optionally, determining the target field of view from multiple fields of view available from the display panel may include the following operations:

[0183] In response to establishing a communication connection with a mobile device, a target area is determined from a first area and a second area based on the location information of the mobile device; and a field of view facing the target area is determined as the target field of view.

[0184] For example, if the location point indicated by the location information of the mobile device is close to the first region, and the average distance between them is less than a preset distance threshold, then the target region can be determined as the first region. If the location point indicated by the location information of the mobile device is close to the second region, and the average distance between them is less than a preset distance threshold, then the target region can be determined as the second region.

[0185] Accordingly, the image to be displayed for the target field of view can be a mobile device image. That is, the mobile device image of a mobile application running on the mobile device can be acquired and used as the image to be displayed for the target field of view. Then, the display panel can be driven to display the mobile device image for the first or second field of view.

[0186] Optionally, in some examples, if the average distance between the location point indicated by the location information of the mobile device and the first area and the average distance between the location point and the second area are both greater than a preset distance threshold, then the target area can be determined to be the third area. In this case, the display panel can be controlled to display the mobile device screen for the third area.

[0187] Figure 5D schematically illustrates the timing diagram of applying a display driving method in a display device according to another embodiment of the present disclosure.

[0188] As shown in Figure 5D, at time t1, the display control system 510 can receive a communication signal from the first mobile device located in the first region 520. The display control system 510 can generate and run a first virtual system. The first mobile screen of the application running on the first mobile device can be sent to the first virtual system. Subsequently, the display control system 510 can control the display panel 540 to display the first mobile screen for the first field of view.

[0189] At time t2, the display control system 510 can receive a communication signal from the second mobile device located in the second region 530. The display control system 510 can generate and run a second virtual system. The second mobile screen of the application running on the second mobile device can be sent to the second virtual system. Then, the display control system 510 can control the display panel 540 to display the first mobile screen for the first field of view and the second mobile screen for the second field of view simultaneously.

[0190] At time t3, the display control system 510 can receive communication signals from the third mobile device located in the third region 550. The display control system 510 can generate and run a third virtual system. The third mobile screen of the application running on the third mobile device can be sent to the third virtual system. Afterwards, the display control system 510 can control the display panel 540 to display the third mobile screen for the third field of view.

[0191] Taking an in-vehicle display scenario as an example, in the example shown in Figure 5D, the display control system can be represented as the vehicle's in-vehicle system, and the display device equipped with the display panel can be the vehicle's dual-view display screen. The first area can represent the driver's area, the first field of view can represent the driver's field of view, the first virtual system can represent the driver's virtual system, and the first mobile device can represent the driver's mobile terminal. The second area can represent the passenger area, the second field of view can represent the passenger's field of view, the second virtual system can represent the passenger's virtual system, and the second mobile device can represent the passenger's mobile terminal. The third area can represent the rear area, the second field of view can represent the rear field of view, the third virtual system can represent the rear virtual system, and the third mobile device can represent the rear mobile terminal.

[0192] After the vehicle is started, the in-vehicle system can receive the registration request from the dual-view display and establish a communication connection with at least one of the driver's mobile terminal, the passenger's mobile terminal, and the rear-seat mobile terminal.

[0193] Upon receiving a mobile terminal signal, the location of the mobile terminal sending the signal can be used to determine whether the mobile terminal is a driver's side mobile terminal, a passenger's side mobile terminal, or a rear-seat mobile terminal. For example, determining whether a mobile terminal is a driver's side mobile terminal can be based on whether there is someone in the driver's area and whether the relative angle between the mobile terminal and the vehicle's in-vehicle system is within the driver's side angle range.

[0194] Once it is determined that the mobile terminal is the driver's mobile terminal, the in-vehicle system can generate a driver's virtual system and run the relevant software. The screen of the application running on the driver's mobile terminal can be provided to the driver's virtual system. The in-vehicle system can control the dual-view display to show the screen of the application running on the driver's mobile terminal at full resolution or half resolution from the driver's perspective.

[0195] If the mobile terminal also includes a passenger mobile terminal, the in-vehicle system can generate a passenger virtual system and run the relevant software. The screen of the application running on the passenger mobile terminal can be provided to the passenger virtual system. The in-vehicle system can control the dual-view display to show the screen of the application running on the driver's mobile terminal at half resolution from the driver's perspective, and simultaneously show the screen of the application running on the passenger mobile terminal at half resolution from the passenger's perspective.

[0196] Once it is determined that the mobile terminal is a rear-seat mobile terminal, the in-vehicle system can generate a rear-seat virtual system and run relevant software. The screen of the application running on the rear-seat mobile terminal can be provided to the rear-seat virtual system. The in-vehicle system can control the dual-view display screen to display the screen of the application running on the rear-seat mobile terminal at full resolution from the rear-seat perspective.

[0197] Figure 6 schematically illustrates a block diagram of a display driving device according to an embodiment of the present disclosure.

[0198] As shown in Figure 6, the display driving device 600 includes a determining module 610, an acquiring module 620, and a display module 630.

[0199] The determining module 610 is used to determine a target field of view from multiple fields of view provided by the display panel, wherein the multiple fields of view include a first field of view facing a first region and a second field of view facing a second region, and the first region and the second region have no overlapping area or have a partially overlapping area.

[0200] The acquisition module 620 is used to acquire the image to be displayed for the target field of view.

[0201] Display module 630 is used to drive the display panel to display the image to be displayed in the target field of view.

[0202] Any one or more of the modules, submodules, units, and subunits according to embodiments of the present disclosure, or at least part of the functions of any one or more of them, can be implemented in one module. Any one or more of the modules, submodules, units, and subunits according to embodiments of the present disclosure can be implemented by dividing them into multiple modules. Any one or more of the modules, submodules, units, and subunits according to embodiments of the present disclosure can be at least partially implemented as hardware circuitry, such as Field Programmable Gate Arrays (FPGAs), Programmable Logic Arrays (PLAs), Systems-on-Chip, Systems-on-Substrate, Systems-on-Package, Application-Specific Integrated Circuits (ASICs), or implemented in hardware or firmware by any other reasonable means of integrating or packaging circuitry, or implemented in software, hardware, or firmware, or in any suitable combination of any of these three implementation methods. Alternatively, one or more of the modules, submodules, units, and subunits according to embodiments of the present disclosure can be at least partially implemented as computer program modules, which, when run, can perform corresponding functions.

[0203] For example, any plurality of the determining module 610, acquiring module 620, and display module 630 may be combined into one module / unit / subunit, or any one of these modules / units / subunits may be split into multiple modules / units / subunits.

Alternatively, at least one of the determining module 610, the acquiring module 620, and the display module 630 may be implemented at least partially as a computer program module, which can perform corresponding functions when the computer program module is run.

[0204] It should be noted that the display driving device part in the embodiments of this disclosure corresponds to the display driving method part in the embodiments of this disclosure. For a detailed description of the display driving device part, please refer to the display driving method part, which will not be repeated here.

[0205] Embodiments of this disclosure also provide a display device that can be used to implement the display driving method described above.

[0206] Figure 7 schematically illustrates a display device according to an embodiment of the present disclosure.

[0207] As shown in Figure 7, the display device 700 may include a display panel 10 and a controller 20.

[0208] The display panel 10 can be used to provide multiple fields of view, including a first field of view facing a first region and a second field of view facing a second region, wherein the first region and the second region have no overlapping area or have a partial overlapping area.

[0209] The controller 20 can be used to respond to a display driving request, determine a target field of view from multiple fields of view, acquire the image to be displayed for the target field of view, and drive the display panel to display the image to be displayed for the target field of view.

[0210] According to embodiments of this disclosure, when the display panel needs to switch the display field of view or change the displayed image, the target field of view can be determined from the multiple fields of view provided by the display panel, and the display panel can be driven to display the image to be displayed for the target field of view. This can meet the needs of different users to obtain different content through the same display panel, thereby effectively improving the user experience of the display panel.

[0211] Optionally, the display panel can switch between three modes: shared mode, dual-view mode, and privacy mode, each catering to different user needs. For example, when a user requires a wider field of view, the display panel can be switched to shared mode. Alternatively, when a user needs to divide their field of view into left and right views, the display panel can be switched to dual-view mode. And finally, when a user requires a view in only one direction, the display panel can be switched to privacy mode.

[0212] The display panel can be implemented in various ways. As one implementation, the display panel can be composed of multiple functional modules.

[0213] Figure 8 schematically illustrates a display device according to another embodiment of the present disclosure.

[0214] As shown in Figure 8, the display panel 10 may include a raster module 11 and a first display module 12. The first display module 12 can be used to display images. The raster module 11 can be used to deflect the display area of ​​the first display module 12 to drive the first display module 12 to display images for a target field of view.

[0215] Optionally, the grating module may include at least a layer structure for controlling the light emission direction. In one example, the layer structure for controlling the light emission direction may be a liquid crystal array, wherein the liquid crystal cells included in the liquid crystal array can control the light emission direction based on their rotation angle.

[0216] Figure 9A schematically illustrates a grating module according to an embodiment of the present disclosure.

[0217] As shown in FIG9A, the grating module 11 may include a first substrate 111, a second substrate 112 and a first liquid crystal array 113 disposed between the first substrate 111 and the second substrate 112.

[0218] A first control electrode 114 may be provided on the side of the first substrate 111 facing the first liquid crystal array 113, and a second control electrode 115 may be provided on the side of the second substrate 112 facing the first liquid crystal array 113.

[0219] The first liquid crystal array 113 includes a plurality of first liquid crystal cell columns 116, and the orthographic projection of the first control electrode 114 and the second control electrode 115 onto the first liquid crystal array 113 covers the plurality of first liquid crystal cell columns 116. That is, in the vertical direction, the first control electrode, the second control electrode and the first liquid crystal cell columns can overlap.

[0220] The first control electrode 114 and the second control electrode 115 can be used to control their orthogonal projection on the first liquid crystal array 113 to cover the first liquid crystal cell column 116, so as to change the rotation angle of the liquid crystal cell 1161 disposed in the first liquid crystal cell column 116.

[0221] The realization of dual-view mode and privacy mode of the display panel requires that each first liquid crystal cell column can be controlled individually. Optionally, in order to individually control each first liquid crystal cell column, at least one of the first control electrode and the second control electrode includes multiple strip sub-electrodes, each strip sub-electrode's orthogonal projection on the first liquid crystal array covering one first liquid crystal cell column. Thus, the strip sub-electrode can deflect the display area of ​​the first display module by controlling the rotation angle of multiple liquid crystal cells disposed in one first liquid crystal cell column.

[0222] Here, we will take the example of the first control electrode comprising multiple strip sub-electrodes for further explanation.

[0223] Figure 9B schematically illustrates a first control electrode and a second control electrode according to an embodiment of the present disclosure.

[0224] As shown in Figure 9B, the first control electrode 114 can be patterned during fabrication to form multiple strip-shaped sub-electrodes 1141, while the second control electrode 115 can be fabricated without patterning.

[0225] Optionally, when the display panel needs to provide images of different resolutions for different viewing fields, the controller can control the level of the drive signals sent to each of the multiple strip sub-electrodes to control the resolution of the images displayed by the first display module for different viewing fields, such as the resolution of the image displayed for the first viewing field and the resolution of the image displayed for the second viewing field.

[0226] Optionally, the level of the driving signal can distinguish whether the strip sub-electrode is used to deflect light into a first field of view or to deflect light into a second field of view. For example, in one example, a strip sub-electrode with a high level applied can be used to deflect light into the first field of view, and a strip sub-electrode with a low level applied can be used to deflect light into the second field of view.

[0227] Figure 9C schematically illustrates a first control electrode according to an embodiment of the present disclosure.

[0228] As shown in Figure 9C, the multiple strip sub-electrodes may include multiple first sub-electrodes 1142 and multiple second sub-electrodes 1143. The ratio of the number of first sub-electrodes 1142 and second sub-electrodes 1143, and the arrangement of the first sub-electrodes 1142 and second sub-electrodes 1143, are not limited here. In the example shown in Figure 9C, the ratio of the number of first sub-electrodes 1142 and second sub-electrodes 1143 can be 1:2, and the multiple strip sub-electrodes 1141 can be divided into multiple sub-electrode groups, each sub-electrode group including one first sub-electrode 1142 and two second sub-electrodes 1143.

[0229] The controller can be used to send drive signals in a first level state to a plurality of first sub-electrodes 1142 respectively, and send drive signals in a second level state to a plurality of second sub-electrodes 1143 respectively.

[0230] The first sub-electrode 1142 can be used to drive a plurality of liquid crystal cells disposed in the first target liquid crystal cell column to rotate to a first angle in response to a drive signal in a first level state, wherein the orthogonal projection of the first sub-electrode on the first liquid crystal array covers the first target liquid crystal cell column.

[0231] The second sub-electrode 1143 can be used to drive a plurality of liquid crystal cells disposed in the second target liquid crystal cell column to rotate to a second angle in response to a drive signal in a second level state, wherein the orthogonal projection of the second sub-electrode on the first liquid crystal array covers the second target liquid crystal cell column.

[0232] The display panel can be used to display images for a first field of view and a second field of view respectively, that is, the display panel can display images in dual-view mode or privacy mode.

[0233] In the example shown in Figure 9C, the ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 1:2.

[0234] In some embodiments, the ratio of the number of the first sub-electrode and the second sub-electrode, as well as the arrangement of the first sub-electrode and the second sub-electrode, can be freely set according to specific application scenarios to meet the requirements of resolution allocation.

[0235] Figure 9D schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0236] As shown in Figure 9D, if the total resolution of the display panel is H*V, and the ratio between the required resolution of the display panel for the first field of view and the resolution of the display panel for the second field of view is m:n, then the resolution of the display panel for the first field of view can be (m*H / (m+n))*V, and the resolution of the display panel for the second field of view can be (n*H / (m+n))*V.

[0237] Every m+n strip-shaped sub-electrodes of the first control electrode can form a sub-electrode group. Each sub-electrode group can include m first sub-electrodes 1142 and n second sub-electrodes 1143. In the first sub-electrode group, the m first sub-electrodes 1142 and the n second sub-electrodes 1143 can be used for display in the first field of view. In the second sub-electrode group, the m first sub-electrodes 1142 and the n second sub-electrodes 1143 can be used for display in the first field of view. This process is repeated to achieve a ratio of m:n between the resolution of the image displayed in the first field of view and the resolution of the image displayed in the second field of view.

[0238] Figure 9E schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0239] As shown in Figure 9E, the ratio of the number of first sub-electrodes 1142 to the number of second sub-electrodes 1143 can be 2:3. Multiple strip-shaped sub-electrodes 1141 can be divided into multiple sub-electrode groups, each of which can include two first sub-electrodes 1142 and three second sub-electrodes 1143. The ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 2:3.

[0240] Figure 9F schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0241] As shown in Figure 9F, the ratio of the number of first sub-electrodes 1142 to the number of second sub-electrodes 1143 can be 1:3. Multiple strip-shaped sub-electrodes 1141 can be divided into multiple sub-electrode groups, each of which can include one first sub-electrode 1142 and three second sub-electrodes 1143. The ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 1:3.

[0242] Figure 9G schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0243] As shown in Figure 9G, the ratio of the number of first sub-electrodes 1142 to the number of second sub-electrodes 1143 can be 2:1. Multiple strip-shaped sub-electrodes 1141 can be divided into multiple sub-electrode groups, each of which can include two first sub-electrodes 1142 and one second sub-electrode 1143. The ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 2:1.

[0244] Figure 9H schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0245] As shown in Figure 9H, the ratio of the number of first sub-electrodes 1142 to the number of second sub-electrodes 1143 can be 3:1. Multiple strip-shaped sub-electrodes 1141 can be divided into multiple sub-electrode groups, each of which can include three first sub-electrodes 1142 and one second sub-electrode 1143. The ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 3:1.

[0246] Figure 9I schematically illustrates a first control electrode according to another embodiment of the present disclosure.

[0247] As shown in Figure 9I, the ratio of the number of first sub-electrodes 1142 to the number of second sub-electrodes 1143 can be 3:2. Multiple strip-shaped sub-electrodes 1141 can be divided into multiple sub-electrode groups, each of which can include three first sub-electrodes 1142 and two second sub-electrodes 1143. The ratio between the resolution of the image displayed on the display panel for the first field of view and the resolution of the image displayed for the second field of view can be 3:2.

[0248] Optionally, the allocation method of the first sub-electrode and the second sub-electrode can be freely configured, which will not be elaborated here.

[0249] Optionally, when the target field of view is the third field of view, the controller can send drive signals in a third-level state to the multiple strip sub-electrodes respectively; the multiple strip sub-electrodes can be used to drive the multiple liquid crystal cells disposed in the first liquid crystal array to rotate to an initial angle in response to the drive signals in the third-level state; the display panel can be used to display the image for the third field of view. That is, the display panel can display the image in a shared state.

[0250] When the liquid crystal cell is at its initial angle, it will not deflect light. The specific value of this initial angle can be determined according to the specific application scenario, and will not be elaborated here.

[0251] Optionally, both the first control electrode and the second control electrode can be patterned into multiple strip-shaped sub-electrodes. In this case, the multiple strip-shaped sub-electrodes of the first control electrode and the multiple strip-shaped sub-electrodes of the second control electrode should coincide in the vertical direction.

[0252] In one embodiment of this disclosure, the first display module may include a pixel array made of a photoluminescent material or device. The photoluminescent material may be, for example, a liquid crystal material.

[0253] Figure 10 schematically illustrates a first display module according to an embodiment of the present disclosure.

[0254] As shown in Figure 10, the first display module 12 includes a third substrate 121, a fourth substrate 122, and a second liquid crystal array 123 disposed between the third substrate 121 and the fourth substrate 122.

[0255] A third control electrode 124 is provided on the side of the third substrate 121 facing the second liquid crystal array 123. A fourth control electrode 125 is provided on the side of the fourth substrate 122 facing the second liquid crystal array 123.

[0256] The third control electrode 124 and the fourth control electrode 125 have their orthographic projections on the second liquid crystal array 123 coincide, and the third control electrode 124 and the fourth control electrode 125 can be used to drive the second liquid crystal array 123.

[0257] The fourth control electrode 125 may have a TFT electrode structure.

[0258] Since the pixel array of the first display module is a second liquid crystal array, that is, the corresponding pixel unit is made of liquid crystal material, in order to excite the pixel unit to emit light, the display panel may also include a backlight structure for providing a backlight source.

[0259] Figure 11 schematically illustrates a display panel according to another embodiment of the present disclosure.

[0260] As shown in Figure 11, the display panel may further include a backlight module 13, which can be used to provide a backlight source to the first display module 12 so that the first display module 12 can display an image. The display panel may be provided with a backlight module 13, a raster module 11 and a first display module 12 from bottom to top.

[0261] Optionally, the first liquid crystal cell column and the second liquid crystal cell column may overlap in the vertical direction so that the first liquid crystal cell column deflects the light emitted from the second liquid crystal cell column.

[0262] In the example shown in FIG11, the second liquid crystal array 123 includes a plurality of second liquid crystal cell columns. The orthographic projection of the strip sub-electrode 1141a on the second liquid crystal array 123 can cover the second liquid crystal cell column 126a, and the orthographic projection of the strip sub-electrode 1141a on the first liquid crystal array 113 can cover the first liquid crystal cell column 116a. The first liquid crystal cell column 116a can be used to deflect the light provided to the second liquid crystal cell column 126a by the backlight module 13.

[0263] Optionally, the positions of the grating module 11 and the first display module 12 can be interchanged, which is not limited here.

[0264] Optionally, compensation film layers may be respectively disposed above the third substrate 121 and below the fourth substrate 122. For example, one of the two compensation film layers may be a +C compensation film and the other may be a -C compensation film. Alternatively, when the grating module 11 is located above the first display model 12, the two compensation film layers may also be disposed above the first substrate 111 and below the second substrate 112, respectively, without limitation.

[0265] Optionally, a polarizer may also be provided near each compensation film layer. For example, a polarizer provided near one compensation film layer can achieve +45° polarization, and a polarizer provided near another compensation film layer can achieve -45° polarization. Through these two polarizers, the light emitted from the first display module can be collimated.

[0266] In another embodiment of this disclosure, the first display module may include a pixel array made of a self-emissive material or device.

[0269] A fifth control electrode 1271 is provided on the side of the fifth substrate 127 facing the first light-emitting unit array 128. The fifth control electrode 1271 can be used to drive the first light-emitting unit array 128 to emit light.

[0270] Optionally, the fifth control electrode 1271 may have a TFT electrode structure.

[0271] Figure 13 schematically illustrates a display panel according to another embodiment of the present disclosure.

[0272] As shown in FIG13, the first light-emitting unit array 128 may include a plurality of first light-emitting unit columns 129. The orthographic projection of the strip sub-electrode 1141b on the first light-emitting unit array 128 may cover the first light-emitting unit column 129b, and the orthographic projection of the strip sub-electrode 1141b on the first liquid crystal array 113 may cover the first liquid crystal unit column 116b. The first liquid crystal unit column 116b may be used to deflect the light emitted by the first light-emitting unit column 129b. In the display panel of the present disclosure embodiment, the grating module 11 may be located above the first display module 12.

[0273] Optionally, compensation film layers may be provided above the first substrate 111 and below the second substrate 112, respectively. For example, one of the two compensation film layers may be a +C compensation film and the other may be a -C compensation film.

[0274] Optionally, a polarizer may also be provided near each compensation film layer. For example, a polarizer provided near one compensation film layer can achieve +45° polarization, and a polarizer provided near another compensation film layer can achieve -45° polarization. Through these two polarizers, the light emitted from the first display module can be collimated.

[0275] As another way to implement a display panel, the display panel can consist of only a single functional module, that is, the functional module can simultaneously emit light and deflect the emitted light.

[0276] Figure 14 schematically illustrates a display device according to another embodiment of the present disclosure.

[0277] As shown in Figure 14, the display panel 10 may include a second display module 14. The second display module 14 may be a flexible module, such as a rollable screen or a stretchable screen, or it may be a rigid module, which is not limited here.

[0278] The second display module 14 may include a sixth substrate 141 and a second light-emitting unit array 142 disposed on the sixth substrate 141.

[0279] The second light-emitting unit array 142 may include a plurality of light-emitting units 143. Each light-emitting unit 143 may include two sub-light-emitting unit groups, and each sub-light-emitting unit group may include a plurality of sub-light-emitting units 144 for displaying multiple colors. Specifically, the two sub-light-emitting units 144 for displaying the same color in the two sub-light-emitting unit groups are arranged adjacent to each other along a first direction.

[0280] Optionally, the first direction can be represented as the column direction of the second light-emitting unit array 142. Taking an RGB light-emitting unit as an example, each sub-light-emitting unit group of the light-emitting unit can include sub-light-emitting units for displaying red, blue and green respectively. Two sub-light-emitting units for displaying red can be arranged adjacent to each other along the first direction, two sub-light-emitting units for displaying blue can be arranged adjacent to each other along the first direction, and two sub-light-emitting units for displaying green can be arranged adjacent to each other along the first direction.

[0281] Figure 15A schematically illustrates a light-emitting unit according to an embodiment of the present disclosure.

[0282] As shown in Figure 15A, the light-emitting unit 143 may include sub-light-emitting units 144a, 144b, 144c, 144d, 144e, and 144f. Sub-light-emitting units 144a, 144c, and 144e belong to the first sub-light-emitting unit group, while sub-light-emitting units 144b, 144d, and 144f belong to the second sub-light-emitting unit group. Sub-light-emitting units 144a and 144b can be arranged adjacent to each other along the column direction of the second light-emitting unit array, as can sub-light-emitting units 144c and 144d, and sub-light-emitting units 144e and 144f. Sub-light-emitting units 144a and 144b can be used to display green at different gray levels, sub-light-emitting units 144c and 144d can be used to display red at different gray levels, and sub-light-emitting units 144e and 144f can be used to display blue at different gray levels.

[0283] The second display module may further include multiple black matrices, which can be respectively disposed in multiple light-emitting units 143. For each light-emitting unit 143, the number of black matrices disposed in that light-emitting unit 143 can be the same as the number of sub-light-emitting units contained in that light-emitting unit 143. The multiple black matrices can be disposed at intervals with the multiple sub-light-emitting units, and the black matrices are used to limit the emission angle of the sub-light-emitting units.

[0284] Optionally, the height of the black matrix in the vertical direction can be higher than the height of the sub-emitting units in the vertical direction, so that the black matrix can limit the emission angle of the sub-emitting units. Furthermore, for a black matrix spaced apart from a sub-emitting unit, the orthographic projection of the black matrix onto the second emitting unit array can be spaced from the sub-emitting unit. The spacing between the orthographic projection of the black matrix onto the second emitting unit array and the sub-emitting units, the spacing between adjacent sub-emitting units, and the height difference between the black matrix and the sub-emitting units in the vertical direction can be set according to the light-shielding requirements of the specific application scenario, and are not limited here.

[0285] For every two sub-light-emitting units used to display the same color, one of the two sub-light-emitting units has a black matrix spaced apart at its first boundary along the second direction, and the other sub-light-emitting unit has a black matrix spaced apart at its second boundary along the second direction, wherein the first direction intersects the second direction.

[0286] The second direction can be, for example, the row direction of the second light-emitting unit array 142. When the sub-light-emitting unit is rectangular, it can have two sides along the second direction, and the two boundaries of the sub-light-emitting unit along the second direction refer to the two sides of the sub-light-emitting unit along the second direction. When the sub-light-emitting unit is circular, hexagonal, or other non-rectangular, a rectangular envelope pattern can be set based on the shape of the sub-light-emitting unit. This rectangular envelope pattern can have two sides along the second direction, and the two boundaries of the sub-light-emitting unit along the second direction refer to the two sides of the rectangular envelope pattern of the sub-light-emitting unit along the second direction.

[0287] For example, in the example shown in Figure 15A, the light-emitting unit 143 can be provided with six black matrices, namely black matrix 145a, black matrix 145b, black matrix 145c, black matrix 145d, black matrix 145e, and black matrix 145f. The two boundaries of the sub-light-emitting unit along its second direction can be the left boundary and the right boundary of the sub-light-emitting unit, respectively.

[0288] Black matrix 145a can be positioned at the right boundary of sub-light-emitting unit 144a, and the distance between the orthographic projection of black matrix 145a on the second light-emitting unit array and the right boundary of sub-light-emitting unit 144a can be d1. Black matrix 145b can be positioned at the left boundary of sub-light-emitting unit 144b, and the distance between the orthographic projection of black matrix 145b on the second light-emitting unit array and the left boundary of sub-light-emitting unit 144b can be d2. Black matrix 145c can be positioned at the right boundary of sub-light-emitting unit 144c, and the distance between the orthographic projection of black matrix 145c on the second light-emitting unit array and the right boundary of sub-light-emitting unit 144c can be d1. Black matrix 145d can be positioned at the left boundary of sub-light-emitting unit 144d, and the distance between the orthographic projection of black matrix 145d on the second light-emitting unit array and the left boundary of sub-light-emitting unit 144d can be d2. The black matrix 145e can be positioned at the right boundary of the sub-light-emitting unit 144e, and the distance between the orthographic projection of the black matrix 145e on the second light-emitting unit array and the right boundary of the sub-light-emitting unit 144e can be d3. The black matrix 145f can be positioned at the left boundary of the sub-light-emitting unit 144f, and the distance between the orthographic projection of the black matrix 145f on the second light-emitting unit array and the left boundary of the sub-light-emitting unit 144f can be d4.

[0289] The intervals d1, d2, d3, and d4 can be set between 1µm and 15µm.

[0290] The black matrix 145a can be used to block the propagation of green light of different gray levels emitted by sub-emitting unit 144a to the right. The black matrix 145b can be used to block the propagation of green light of different gray levels emitted by sub-emitting unit 144b to the left. The black matrix 145c can be used to block the propagation of red light of different gray levels emitted by sub-emitting unit 144c to the right. The black matrix 145d can be used to block the propagation of red light of different gray levels emitted by sub-emitting unit 144d to the left. The black matrix 145e can be used to block the propagation of blue light of different gray levels emitted by sub-emitting unit 144e to the right. The black matrix 145f can be used to block the propagation of blue light of different gray levels emitted by sub-emitting unit 144f to the left.

[0291] Therefore, by utilizing the black matrix provided in the light-emitting unit, the sub-light-emitting units 144a, 144c, and 144e can emit light to the left, and the sub-light-emitting units 144b, 144d, and 144f can emit light to the right, thereby enabling the display panel to provide different content in the left and right directions.

[0292] In the light-emitting unit 143, the distance between adjacent black matrices can be greater than the distance between the orthographic projection of the black matrix on the second light-emitting unit array and the boundary of the sub-light-emitting unit. For example, in the example shown in FIG15A, black matrix 145c can be arranged adjacent to black matrix 145f, and the distance between black matrix 145c and black matrix 145f can be d5, where d5 can be greater than d1 / d2 / d3 / d4. This ensures that the black matrix does not obstruct the emission angle of other sub-light-emitting units besides those adjacent to it. For example, black matrix 145a can be adjacent to sub-light-emitting units 144a and 144e respectively, and the distance between the right boundary of black matrix 145a and the right boundary of sub-light-emitting unit 144a can be less than the distance between the left boundary of black matrix 145a and the left boundary of sub-light-emitting unit 144e. This allows black matrix 145a to only obstruct sub-light-emitting unit 144a from emitting light to the right, without obstructing sub-light-emitting unit 144e from emitting light to the left.

[0293] Optionally, in the second light-emitting unit array, the distance between adjacent light-emitting units in the second direction can also be greater than the interval distance d1 / d2 / d3 / d4, so as to avoid the black matrix set in one light-emitting unit from obstructing the light emission angle of another light-emitting unit. This will not be elaborated here.

[0294] Optionally, the second light-emitting unit array may include multiple second light-emitting unit columns, each of which can be controlled independently to achieve free adjustment of the resolution of the display panel and free adjustment of the field of view in the display panel used for image display.

[0295] Figure 15B schematically illustrates a second light-emitting unit array according to an embodiment of the present disclosure.

[0296] As shown in Figure 15B, the second light-emitting unit array 142 may include a plurality of second light-emitting unit columns 146, and each second light-emitting unit column may include a plurality of light-emitting units 143 as shown in Figure 15A.

[0297] The sixth substrate 141 has a sixth control electrode on its side facing the second light-emitting unit array 142. The sixth control electrode can be used to control the light emission state of the two sub-light-emitting unit groups included in each of the multiple light-emitting units 143 included in each of the multiple second light-emitting unit columns 146, so as to control the resolution of the image displayed by the second display module for the first field of view and the resolution of the image displayed by the first display module for the second field of view.

[0298] The light emission state of the sub-light-emitting unit group can include, for example, emitting light or not emitting light. For example, the resolution of the second light-emitting array 146 after being fully deployed is (H+X)*V. Under the control of the sixth control electrode, if all the sub-light-emitting units in the second light-emitting array 146 can be controlled to emit light, then the resolution of the image displayed by the second display module for the first field of view and the resolution of the image displayed by the first display module for the second field of view can both be (H+X)*V. If the sub-light-emitting units in the H columns of the second light-emitting unit group in the second light-emitting array 146 that emit light for the first field of view can be controlled to emit light, and the sub-light-emitting units in the X columns of the second light-emitting unit group in the second light-emitting array 146 that emit light for the first field of view can be controlled to emit light, then the resolution of the image displayed by the second display module for the first field of view can be H*V, and the resolution of the image displayed for the second field of view can be X*V. If the sub-light-emitting units in the H columns of the second light-emitting unit array 146 used for emitting light in the first field of view can be controlled to emit light, and all sub-light-emitting units in the X columns of the second light-emitting unit array 146 can be controlled to emit light, then the resolution of the image displayed by the second display module for the first field of view can be (H+X)*V, and the resolution of the image displayed for the second field of view can be X*V. Therefore, through the control action of the sixth control electrode, the resolution of the image displayed by the second display module for the first field of view and the resolution of the image displayed by the first display module for the second field of view can be freely adjusted.

[0299] For example, in the example shown in Figure 15B, the first field of view can be represented as the left field of view, the second field of view can be represented as the right field of view, and correspondingly, the sub-light-emitting unit used to emit light for the first field of view can be represented as the left sub-light-emitting unit, and the sub-light-emitting unit used to emit light for the second field of view can be represented as the right sub-light-emitting unit.

[0300] When a resolution ratio of 1:2 between the left and right fields of view is required, as a control method, the left sub-light-emitting units of the 1st, 4th, 7th, ..., 1+3kth second light-emitting unit columns can be controlled to emit light to display left-view video or image content, while the right sub-light-emitting units of the 1st, 4th, 7th, ..., 1+3kth second light-emitting unit columns are controlled to not emit light. The left sub-light-emitting units of the remaining second light-emitting unit columns are controlled to not emit light, while the right sub-light-emitting units of the remaining second light-emitting unit columns are controlled to emit light to display right-view video or image content, thereby achieving a resolution ratio of 1:2 between the left and right fields of view.

[0301] As another control method, the left-view sub-light-emitting units of the second light-emitting unit column in odd-numbered columns can be controlled to emit light to display left-view video or image content, while the left-view sub-light-emitting units of the second light-emitting unit column in even-numbered columns can be controlled to not emit light, and the right-view sub-light-emitting units of all second light-emitting unit columns can be controlled to emit light to display right-view video or image content, thereby achieving a resolution ratio of 1:2 between the left-view field of view and the right-view field of view.

[0302] Optionally, by using the sixth control electrode, the field of view targeted by the second display module when displaying an image can also be controlled by controlling the light emission state of the two sub-light emission unit groups included in each of the multiple light emission units in the multiple second light emission unit columns.

[0303] For example, the sixth control electrode can control the sub-light-emitting unit group in the second light-emitting unit array to emit light for the first field of view, while the sub-light-emitting unit group for the second field of view does not emit light or emits light at a gray level of 0. In this case, the field of view targeted by the second display module when displaying the image is the first field of view. That is, the display panel can display the image for the first field of view, but not for the second field of view, or only display a pure black image for the second field of view, so that the display panel is in a privacy mode.

[0304] For example, the sixth control electrode can control both the sub-light-emitting unit group for emitting light in the first field of view and the sub-light-emitting unit group for emitting light in the second light-emitting unit array to emit light. In this case, the second display module targets both the first and second field of view when displaying the image. That is, the display panel can simultaneously display the image in both the first and second field of view, making the display panel a dual-view state.

[0305] Optionally, the sixth control electrode can also be used to control the grayscale level of each of the two sub-light-emitting unit groups included in each of the multiple light-emitting units, so as to control the image displayed by the second display module for each of the multiple fields of view.

[0306] For example, the sixth control electrode is used to drive the two sub-light-emitting unit groups included in each of the multiple light-emitting units to emit light based on different grayscale levels. That is, the sixth control electrode can control the sub-light-emitting unit groups in the second light-emitting unit array that emit light for the first field of view and the corresponding sub-light-emitting unit groups that emit light for the second field of view to emit light based on different grayscale levels. At this time, the field of view targeted by the second display module when displaying the image is the first field of view and the second field of view. That is, the display panel can be used to display images for the first field of view and the second field of view respectively, and the images displayed in the first field of view and the second field of view are different, so that the display panel is in a dual-view state.

[0307] For example, the sixth control electrode can also be used to drive the two sub-light-emitting unit groups included in each of the multiple light-emitting units to emit light based on the same grayscale level. That is, the sixth control electrode can control the sub-light-emitting unit groups in the second light-emitting unit array that emit light for the first field of view and the corresponding sub-light-emitting unit groups that emit light for the second field of view to emit light based on the same grayscale level. In this case, the field of view targeted by the second display module when displaying the image can be a fourth field of view, which can simultaneously include the first field of view and the second field of view. That is, the viewing angle range represented by the fourth field of view can include the viewing angle ranges represented by the first field of view and the second field of view, respectively. In other words, the display panel can be used to display the image for the fourth field of view, or it can be used to display the same image for the first field of view and the second field of view, so that the display panel is in a shared state.

[0308] According to embodiments of this disclosure, by using the display panel described above, the power consumption of the display panel can be reduced and the user experience of the display panel can be improved while meeting the needs of multiple users at different angles to view different content.

[0313] According to embodiments of this disclosure, by equipping a vehicle with an in-vehicle display as described above, the operating mode of the in-vehicle display can be dynamically adjusted according to the situation of the driver / passenger, thereby meeting the needs of the driver and passenger for viewing content while reducing the power consumption of the in-vehicle display and improving the experience of using the display device while in the vehicle.
