Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention application clearer, the technical solutions in the embodiments of this invention application will be clearly and completely described below in conjunction with the embodiments of this invention application. Obviously, the described embodiments are only some embodiments of this invention application, not all embodiments. Based on the embodiments of this invention application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] In this field, the most common display mode switching is full-screen switching. If the entire screen is in the first display mode (non-peeping mode) or the second display mode (peeping mode), it is difficult to achieve a situation where some areas of the display panel 100 are in the first display mode and some areas are in the second display mode.

[0032] Figure 1 This is a schematic diagram of the structure of a display panel provided in one embodiment of this application. Figure 1 As shown, this application embodiment provides a display panel 100 including: multiple rows of pixel groups 110, each pixel group 110 including multiple sub-pixels 111 of different display modes; a driving module 120, the driving module 120 being connected to the multiple sub-pixels 111 included in each of the multiple rows of pixel groups 110; wherein, the driving module 120 is configured to output scanning signals to the multiple sub-pixels 111 included in the pixel group 110 at different times.

[0033] Each sub-pixel 111 can individually implement different display modes. For example, one sub-pixel 111 can be in the first display mode (non-peeping mode), and the other sub-pixel 111 can be in the second display mode (peeping mode).

[0034] In this embodiment, pixel group 110 includes a red pixel group, a green pixel group, and a blue pixel group. Pixel groups 110 of different colors can be in different display modes, such as the red pixel group in a first display mode, the green pixel group in a second display mode, and the blue pixel group in a third display mode; different pixel groups 110 can also be in the same display mode, such as the red pixel group, green pixel group, and blue pixel group all being in the first display mode. For example, when the red pixel group is in the first display mode, in this red pixel group, only the sub-pixels that can achieve the first display mode are active, while the remaining sub-pixels are inactive; or, in this red pixel group, the grayscale of the sub-pixels that can achieve the first display mode is not 0, while the grayscale of the remaining sub-pixels is 0.

[0035] The driving module 120 is connected to the multiple sub-pixels 111 included in each of the multi-row pixel groups 110. At different times, it outputs scanning signals to the sub-pixels 111 of different display modes to perform scanning processing on the sub-pixels 111 that receive the scanning signals, thereby realizing the individual control of the grayscale of the sub-pixels 111 of different display modes in each pixel group 110, and thus realizing the individual control of the display mode of each pixel group 110.

[0036] This embodiment can switch the display mode of at least a portion of the display panel 100, and the minimum switching range is one pixel group 110, providing users with a highly accurate switching range and improving the user experience.

[0037] In some embodiments, Figure 2 This is a schematic diagram illustrating the specific structure of a display panel provided in one embodiment of this application. For example... Figure 2 As shown, the driving module 120 includes multiple first gate driving sub-modules 121 connected in sequence, and also includes multiple control sub-modules 122. The multiple first gate driving sub-modules 121 and multiple control sub-modules 122 correspond one-to-one. Each first gate driving sub-module 121 and its corresponding control sub-module 122 correspond to a row of pixel groups 110. Each first gate driving sub-module 121 is connected to the corresponding row of pixel groups 110 through its corresponding control sub-module 122. Specifically, the first gate driving sub-modules 121 and control sub-modules 122, and the control sub-modules 122 and sub-pixels 111 are connected via scan traces. The first gate driving sub-module 121 transmits scan signals to the sub-pixels 111.

[0038] Optionally, the control submodule 122 includes a first control unit 122a and a second control unit 122b, and a plurality of sub-pixels 111 including first sub-pixels 111a and second sub-pixels 111b. One end of the first control unit 122a is connected to the second sub-pixel 111b of the corresponding row of pixel group 110, and the other end is connected to the corresponding first gate driving submodule 121. One end of the second control unit 122b is connected to the first sub-pixel 111a of the corresponding row of pixel group 110, and the other end is connected to the corresponding first gate driving submodule 121. Each row of pixel group 110 corresponds to at least one first control unit 122a and at least one second control unit 122b. The plurality of first control units 122a between multiple rows of pixel groups 110 are connected in series by wires, and the plurality of second control units 122b between multiple rows of pixel groups 110 are connected in series by wires.

[0039] Optionally, the first control unit 122a of the plurality of control submodules 122 is configured to be disconnected in a first time period and turned on in a second time period; the second control unit 122b of the plurality of control submodules 122 is configured to be turned on in the first time period and disconnected in the second time period.

[0040] The first control unit 122a and the second control unit 122b are transistor structures, each with two states: on and off. When one is on, the other is off. The first control unit 122a and the second control unit 122b are of the same type of transistor, such as both being N-type transistors, or both being P-type transistors. For N-type transistors, they exhibit the characteristic of being off under low voltage and on under high voltage; for P-type transistors, they exhibit the characteristic of being off under high voltage and on under low voltage.

[0041] Figure 2 Both the first control unit 122a and the second control unit 122b are P-type transistors. It is understandable that both the first control unit 122a and the second control unit 122b could also be N-type transistors.

[0042] Figure 3 This is a timing diagram of a display panel provided in one embodiment of this application. Figure 3 As shown, during the first time period, a high level is applied to the first control unit 122a and a low level is applied to the second control unit 122b; during the second time period, a low level is applied to the first control unit 122a and a high level is applied to the second control unit 122b. It is worth noting that the timing of the display panel 100 changes periodically, and each cycle includes the first time period and the second time period. The level changes in the other cycles are not described in detail.

[0043] The first gate driving submodule 121 is configured to sequentially output scan signals to the first sub-pixel 111a of the multi-row pixel group 110 during a first time period, and sequentially output scan signals to the second sub-pixel 111b of the multi-row pixel group 110 during a second time period.

[0044] The first control unit of the multiple control submodules is connected to the first control signal; the second control unit of the multiple control submodules is connected to the second control signal.

[0045] Specifically, when both the first control unit 122a and the second control unit 122b are N-type transistors, during the first time period, a low level is applied to the first control unit 122a and a high level is applied to the second control unit 122b, i.e., the first control signal is a low level signal and the second control signal is a high level signal, so as to realize that the first control unit 122a is turned off and the second control unit 122b is turned on, and the scan signal output by the first gate driving submodule 121 enters the first sub-pixel 111a through the second control unit 122b; during the second time period, a high level is applied to the first control unit 122a and a low level is applied to the second control unit 122b, i.e., the first control signal is a high level signal and the second control signal is a low level signal, so as to realize that the second control unit 122b is turned off and the first control unit 122a is turned on, and the scan signal output by the first gate driving submodule 121 enters the second sub-pixel 111b through the first control unit 122a. When both the first control unit 122a and the second control unit 122b are P-type transistors, during the first time period, a high level is applied to the first control unit 122a and a low level is applied to the second control unit 122b, i.e., the first control signal is a high level signal and the second control signal is a low level signal, so as to realize that the first control unit 122a is turned off and the second control unit 122b is turned on, and the scan signal output by the first gate driving submodule 121 enters the first sub-pixel 111a through the second control unit 122b; during the second time period, a low level is applied to the first control unit 122a and a high level is applied to the second control unit 122b, i.e., the first control signal is a low level signal and the second control signal is a high level signal, so as to realize that the second control unit 122b is turned off and the first control unit 122a is turned on, and the scan signal output by the first gate driving submodule 121 enters the second sub-pixel 111b through the first control unit 122a.

[0046] It is worth noting that, Figure 3The diagram shown is the timing diagram when both the first control unit 122a and the second control unit 122b are P-type transistors. When both the first control unit 122a and the second control unit 122b are N-type transistors, the timing is as follows: during the first time period, a low level is applied to the first control unit 122a and a high level is applied to the second control unit 122b; during the second time period, a high level is applied to the first control unit 122a and a low level is applied to the second control unit 122b. This is not shown in the diagram here.

[0047] Optionally, the control submodule 122 further includes a third control unit 122c and a fourth control unit 122d. One end of the third control unit 122c is connected to the first sub-pixel 111a of the corresponding row of pixel group 110, and the other end is connected to a high-level voltage signal. One end of the fourth control unit 122d is connected to the second sub-pixel 111b of the corresponding row of pixel group 110, and the other end is connected to the high-level voltage signal. Each row of pixel group 110 corresponds to at least one third control unit 122c and at least one fourth control unit 122d. Multiple third control units 122cs between multiple rows of pixel groups 110 are connected in series through wires, and multiple fourth control units 122ds between multiple rows of pixel groups 110 are connected in series through wires. The high-level voltage signal is transmitted through a high-level voltage wire 130.

[0048] Optionally, the third control unit of the plurality of control submodules 122 is connected to the first control signal; the fourth control unit of the plurality of control submodules 122 is connected to the second control signal.

[0049] Optionally, the third control unit 122c of the plurality of control submodules 122 is configured to be disconnected in a first time period and turned on in a second time period; the fourth control unit 122d of the plurality of control submodules 122 is configured to be turned on in the first time period and disconnected in the second time period.

[0050] The third control unit 122c and the fourth control unit 122d are transistor structures, each with both on and off states; when one is on, the other is off. The third control unit 122c and the fourth control unit 122d are of the same type of transistor, such as both being N-type transistors, or the first control unit 122a and the second control unit 122b being P-type transistors.

[0051] Optionally, the high-voltage signal is input to the second sub-pixel 111b of the multi-row pixel group 110 in the first time period and to the first sub-pixel 111a of the multi-row pixel group 110 in the second time period.

[0052] Specifically, when both the third control unit 122c and the fourth control unit 122d are N-type transistors, in the first time period, a low level is applied to the third control unit 122c and a high level is applied to the fourth control unit 122d. That is, the first control signal is a low level signal and the second control signal is a high level signal, so as to realize that the third control unit 122c is turned off and the fourth control unit 122d is turned on, and the high level voltage signal enters the second sub-pixel 111b through the fourth control unit 122d. In the second time period, a high level is applied to the third control unit 122c and a low level is applied to the fourth control unit 122d. That is, the first control signal is a high level signal and the second control signal is a low level signal, so as to realize that the fourth control unit 122d is turned off and the third control unit 122c is turned on, and the high level voltage signal enters the first sub-pixel 111a through the third control unit 122c. When both the third control unit 122c and the fourth control unit 122d are P-type transistors, in the first time period, a high level is applied to the third control unit 122c and a low level is applied to the fourth control unit 122d. That is, the first control signal is a high level signal and the second control signal is a low level signal, so as to realize that the third control unit 122c is turned off and the fourth control unit 122d is turned on, and the high level voltage signal enters the second sub-pixel 111b through the fourth control unit 122d. In the second time period, a low level is applied to the third control unit 122c and a high level is applied to the fourth control unit 122d. That is, the first control signal is a low level signal and the second control signal is a high level signal, so as to realize that the fourth control unit 122d is turned off and the third control unit 122c is turned on, and the high level voltage signal enters the first sub-pixel 111a through the third control unit 122c.

[0053] It is worth noting that the timing of the third control unit 122c and the fourth control unit 122d is similar to... Figure 3 Similarly, no illustration is provided here.

[0054] In summary, when the first control unit 122a, the second control unit 122b, the third control unit 122c, and the fourth control unit 122d are all N-type transistors, in the first time period, the scan signal output by the first gate driving submodule 121 enters the first sub-pixel 111a through the second control unit 122b, and the high-level voltage signal enters the second sub-pixel 111b through the fourth control unit 122d; in the second time period, the scan signal output by the first gate driving submodule 121 enters the second sub-pixel 111b through the first control unit 122a, and the high-level voltage signal enters the first sub-pixel 111a through the third control unit 122c. When the first control unit 122a, the second control unit 122b, the third control unit 122c, and the fourth control unit 122d are all P-type transistors, in the first time period, the scan signal output by the first gate driving submodule 121 enters the first sub-pixel 111a through the second control unit 122b; the high-level voltage signal enters the second sub-pixel 111b through the fourth control unit 122d; in the second time period, the scan signal output by the first gate driving submodule 121 enters the second sub-pixel 111b through the first control unit 122a, and the high-level voltage signal enters the first sub-pixel 111a through the third control unit 122c.

[0055] It is worth noting that the scanning signal input time of the first sub-pixel 111a and the second sub-pixel 111b can be changed, but this will not be elaborated on here.

[0056] For example, the first control unit 122a, the second control unit 122b, the third control unit 122c, and the fourth control unit 122d can be low-temperature polycrystalline silicon thin-film transistors (LTPS TFTs) or low-temperature polycrystalline oxide thin-film transistors (LTPO TFTs).

Figure 5 This is a circuit diagram of a second sub-pixel, a first control unit, and a fourth control unit provided in an embodiment of this application. Figure 4 As shown, both the transistor in the first sub-pixel 111a and the second control unit 122b are LTPO TFTs, and the second control unit 122b is a P-type transistor. Figure 5 As shown, the transistor in the second sub-pixel 111b and the first control unit 122a are both LTPS TFTs, and the first control unit 122a is a P-type transistor. It is worth noting that... Figure 4 and Figure 5 The circuits of the first sub-pixel 111a111a and the second sub-pixel 111b are described only using 7T1C circuits, and this application does not limit the circuits of the first sub-pixel 111a and the second sub-pixel 111b.

[0057] Optionally, the first sub-pixel 111a is a regular sub-pixel, and the second sub-pixel 111b is a privacy-protected sub-pixel. When the grayscale of the first sub-pixel 111a is not zero, while the grayscale of the second sub-pixel 111b is zero, the pixel group 110 presents a non-privacy-protected display mode; when the grayscale of the second sub-pixel 111b is not zero, while the grayscale of the first sub-pixel 111a is zero, the pixel group 110 presents a privacy-protected display mode. Alternatively, when the first sub-pixel 111a is active, while the second sub-pixel 111b is inactive, the pixel group 110 presents a non-privacy-protected display mode; when the second sub-pixel 111b is active, while the first sub-pixel 111a is inactive, the pixel group 110 presents a privacy-protected display mode.

[0058] Optionally, the driving module 120 further includes a source driving submodule 125, which is connected to a plurality of sub-pixels 111 included in the pixel group 110. The source driving submodule 125 is configured to output data voltage to the sub-pixels 111 receiving the scan signal. The source driving submodule 125 is connected to the plurality of sub-pixels 111 included in the pixel group 110 through data traces and transmits the data voltage to the sub-pixels 111 receiving the scan signal through the data traces.

[0059] Optionally, during the first time period, the scan signal and data voltage corresponding to the first sub-pixel 111a are input to the first sub-pixel 111a; during the second time period, the scan signal and data voltage corresponding to the second sub-pixel 111b are input to the second sub-pixel 111b.

[0060] In this embodiment, by setting a first gate driving submodule 121, a first control unit 122a, and a second control unit 122b, and applying high or low levels to the first control unit 122a and the second control unit 122b at different time periods, scanning signals are output to sub-pixels 111 of different display modes at different times. This allows the sub-pixels 111 receiving the scanning signals to undergo scanning processing, enabling data voltage to be input to the sub-pixels 111 of different display modes at different times, thereby achieving individual control of the display mode of each pixel group 110. This embodiment can switch the display mode of at least a portion of the display panel 100, with a minimum switching range of one pixel group 110, providing users with a highly accurate switching range and improving the user experience.

[0061] Figure 6 This is a schematic diagram illustrating the specific structure of a display panel provided in another embodiment of this application. For example... Figure 6 As shown, in some embodiments, the driving module 120 includes a plurality of second gate driving sub-modules 123 and a plurality of third gate driving sub-modules 124 connected alternately in sequence, and adjacent second gate driving sub-modules 123 and third gate driving sub-modules 124 correspond to a row of pixel groups 110.

[0062] Optionally, the plurality of sub-pixels 111 include a first sub-pixel 111a and a second sub-pixel 111b, the second gate driving submodule 123 is connected to the first sub-pixel 111a of the pixel group 110 in the corresponding row, and the third gate driving submodule 124 is connected to the second sub-pixel 111b of the pixel group 110 in the corresponding row.

[0063] Optionally, the second gate driving submodule 123 is configured to output a scan signal to the first sub-pixel 111a of the pixel group 110 in the corresponding row; the third gate driving submodule 124 is configured to output a scan signal to the second sub-pixel 111b of the pixel group 110 in the corresponding row.

[0064] Optionally, a plurality of second gate driving submodules 123 and a plurality of third gate driving submodules 124 sequentially and alternately output scanning signals to the first sub-pixel 111a of the pixel group 110 in the corresponding row or the second sub-pixel 111b of the pixel group in the corresponding row.

[0065] Specifically, the second gate driving submodule 123 outputs a scan signal to the first sub-pixel 111a in the first pixel group. At the next moment, the third gate driving submodule 124 outputs a scan signal to the second sub-pixel 111b in the first pixel group. At the next moment after that, the second gate driving submodule 123 outputs a scan signal to the first sub-pixel 111a in the second pixel group. At the next moment after that, the third gate driving submodule 124 outputs a scan signal to the second sub-pixel 111b in the second pixel group. According to this pattern, the second gate driving submodule 123 and multiple third gate driving submodules 124 alternately output scan signals to the first sub-pixel 111a or the second sub-pixel 111b of the corresponding row of pixel group 110.

[0066] Optionally, the first sub-pixel 111a is a regular sub-pixel, and the second sub-pixel 111b is a privacy-protecting sub-pixel.

[0067] The driving module 120 also includes a source driving submodule 125, which is connected to a plurality of sub-pixels 111 included in the pixel group 110. The source driving submodule 125 is configured to output data voltage to the sub-pixels 111 receiving the scan signal. The source driving submodule 125 is connected to the plurality of sub-pixels 111 included in the pixel group 110 through data traces and transmits the data voltage to the sub-pixels 111 receiving the scan signal through the data traces.

[0068] In this embodiment, by setting a second gate driving submodule 123 connected to the first sub-pixel 111a and a third gate driving submodule 124 connected to the second sub-pixel 111b, scanning signals are output to sub-pixels 111 in different display modes at different times without adding control circuitry. The sub-pixels 111 receiving these scanning signals are then scanned, thereby achieving individual control of the display mode for each pixel group 110, resulting in high reliability. This embodiment can switch the display mode of at least a portion of the display panel 100, with a minimum switching range of one pixel group 110, providing users with a highly accurate switching range and improving the user experience.

[0069] In some embodiments, the display panel 100 further includes a first storage submodule 140 and a second storage submodule 150. Figure 7 A schematic diagram illustrating the working principle of the first and second storage submodules in the third time period provided in another embodiment of this application. Figure 8 This is a schematic diagram illustrating the working principle of the first and second storage submodules in the fourth time period, provided in another embodiment of this application. Figure 7 and Figure 8 As shown, the first storage submodule 140 is configured to acquire and store target image data and a privacy protection area control matrix within a third time period, and then transmit the target image data and privacy protection area control matrix within the third time period to the second storage submodule 150. The second storage submodule 150 is configured to acquire and store target image data and a privacy protection area control matrix within a fourth time period, and then transmit the target image data and privacy protection area control matrix within the fourth time period to the first storage submodule 140.

[0070] The first storage submodule 140 is further configured to determine the digital signals of multiple subpixels 111 included in the pixel group 110 within the fourth time period based on the target image data within the fourth time period and the privacy area control matrix; the second storage submodule 150 is further configured to determine the digital signals of multiple subpixels 111 included in the pixel group 110 within the third time period based on the target image data within the third time period and the privacy area control matrix.

[0071] Optionally, the source drive submodule 125 is configured to receive a digital signal, determine a data voltage based on the digital signal, and transmit the data voltage to the sub-pixel 111 that receives the scan signal.

[0072] The privacy protection area control matrix includes multiple location points, which correspond to multiple rows of pixel groups 110 on the display panel 100. The value of each location point includes a first value or a second value. The first value indicates that the pixel group 110 corresponding to the location point is in a first display mode, and the second value indicates that the pixel group 110 corresponding to the location point is in a second display mode.

[0073] Understandably, the first storage submodule 140 acquires and stores the target image data and the privacy area control matrix within the third time period, and transmits the target image data and the privacy area control matrix within the third time period to the second storage submodule 150. The second storage submodule 150 determines the digital signals of the multiple sub-pixels 111 included in the pixel group 110 within the third time period based on the target image data and the privacy area control matrix within the third time period. The source drive submodule 125 determines the data voltage based on the digital signals and transmits the data voltage to the sub-pixels 111 that receive the scanning signals in order to adjust the grayscale of the sub-pixels 111. The second storage submodule 150 acquires and stores the target image data and the privacy area control matrix within the fourth time period, and transmits the target image data and the privacy area control matrix within the fourth time period to the first storage submodule 140. The first storage submodule 140 determines the digital signals of the multiple sub-pixels 111 included in the pixel group 110 within the fourth time period based on the target image data and the privacy area control matrix within the first time period. The source drive submodule 125 determines the data voltage based on the digital signals and transmits the data voltage to the sub-pixels 111 that receive the scanning signals in order to control the grayscale display of the sub-pixels 111.

[0074] In this embodiment, both the first storage submodule 140 and the second storage submodule 150 can store target image data for two time periods, i.e., receiving target image data for one time period while processing target image data for another time period. The first storage submodule 140 and the second storage submodule 150 employ a ping-pong operation, meaning that while one receives target image data, the other processes the target image data and outputs a digital signal. This application allows the privacy protection area to be changed at any time according to user needs. The ping-pong operation used by the first storage submodule 140 and the second storage submodule 150 to store target image data facilitates data retrieval and avoids lag.

[0075] Figure 9 This is a schematic flowchart illustrating a display method for a display panel provided in another embodiment of this application.

[0076] like Figure 9 As shown, this application provides a display method for a display panel, applicable to the display panel mentioned in any of the above embodiments, the display method comprising: Step S101: Obtain target image data and privacy protection area control matrix.

[0077] The privacy protection area control matrix (CPA matrix) consists of multiple location points, each corresponding to a row of pixel groups on the display panel. Each location point has a first or second value. The first value indicates that the pixel group corresponding to the location point is in a first display mode, while the second value indicates that the pixel group is in a second display mode. Target image data refers to the image data used for display on the display panel.

[0078] Specifically, the first value can be binary 1, and the second value can be binary 0. The first display mode can be a non-spy mode, and the second display mode can be a spy mode. This embodiment includes several cases: one location point corresponds to one pixel group; or one location point corresponds to multiple pixel groups. For example, one location point corresponds to three pixel groups, that is, one location point corresponds to the red pixel group, the green pixel group, and the blue pixel group.

[0079] Step S102: Based on the target image data and the privacy region control matrix, determine the grayscale of each sub-pixel included in each pixel group.

[0080] Specifically, this embodiment uses a line-by-line scanning method for screen display.

[0081] The display mode of the pixel group corresponding to each position point is determined based on the value of the position point in the privacy protection area control matrix, i.e., the CPA matrix, and then the grayscale of the sub-pixels in the pixel group that can achieve different display modes is determined.

[0082] Step S103: Control the display panel to display based on the grayscale of each sub-pixel included in each pixel group.

[0083] In this embodiment, optionally, the Timing Controller (TCON) is used to acquire target image data and a privacy protection area control matrix, and calculate the grayscale of each sub-pixel in each pixel group. The source driver submodule is used to determine the data voltage of each sub-pixel in each pixel group based on the grayscale of each sub-pixel in each pixel group. Each sub-pixel in each pixel group is displayed according to the corresponding data voltage. The display driving architecture is not limited to medium and large-sized displays, but also includes small-sized displays. In small-sized displays, the circuitry of the timing controller and the circuitry of the source driver submodule are packaged in the same chip.

[0084] The privacy protection area can be quadrilateral, pentagonal, or hexagonal, etc., and this application does not limit the shape of the privacy protection area. The privacy protection area can be changed by changing the vertex coordinate data. In this application, multiple privacy protection areas can exist simultaneously on the display screen. Figure 10 This is a schematic diagram of a display screen provided in yet another embodiment of this application. For example... Figure 10As shown, regions 1 and 2 are privacy-protected areas, while region 3 is not privacy-protected. The vertex coordinates of region 1 are R1(x1,y1), R1(x2,y2), R1(x3,y3), R1(x4,y4), and the vertex coordinates of region 2 are R2(x1,y1), R2(x2,y2), R2(x3,y3), R2(x4,y4).

[0085] Understandably, the minimum privacy protection area is a group of pixels. For pixel groups located within the privacy protection area, the value of the corresponding position point in the CPA matrix is ​​the second value; for pixel groups located outside the privacy protection area, the value of the corresponding position point in the CPA matrix is ​​the first value. For example, as... Figure 11 As shown, Figure 11 The privacy control matrix diagram corresponding to the display screen provided in another embodiment of this application has a value of 0 in area 1 and area 2, and a value of 1 in area 3.

[0086] In this embodiment, by acquiring target image data and a privacy protection area control matrix, and based on the target image data and the privacy protection area control matrix, the grayscale of each sub-pixel in each pixel group is determined. Based on the grayscale of each sub-pixel in each pixel group, the display panel is controlled to display. This application determines the display mode of each pixel group, and then determines the grayscale of the sub-pixels in each pixel group that can achieve different display modes. In the non-privacy protection area, regular sub-pixels are displayed normally, and privacy protection sub-pixels have 0 grayscale. In the privacy protection area, regular sub-pixels have 0 grayscale, and privacy protection sub-pixels are displayed normally. That is, this application can switch the display mode for at least a portion of the display panel, and the minimum switching range is one pixel group, providing users with a highly accurate switching range and improving the user experience.

[0087] In some embodiments, each pixel group includes multiple sub-pixels, including a first sub-pixel and a second sub-pixel, where the first sub-pixel is a regular sub-pixel and the second sub-pixel is a privacy-protection sub-pixel; step S102 determines the grayscale of each sub-pixel in each pixel group based on the target image data and the privacy-protection region control matrix, including: if the value of the location point corresponding to the pixel group is a first value, then the grayscale value of the target image data at the location point is assigned to the first sub-pixel in the pixel group; the grayscale of the second sub-pixel in the pixel group is determined to be 0 grayscale; if the value of the location point corresponding to the pixel group is a second value, then the grayscale value of the target image data at the location point is assigned to the second sub-pixel in the pixel group; the grayscale of the first sub-pixel in the pixel group is determined to be 0 grayscale.

[0088] Specifically, Figure 12 This is a schematic diagram of the process for determining the gray level of a sub-pixel, provided in another embodiment of this application.

[0089] like Figure 12As shown, the grayscale of each sub-pixel is determined starting from row 0 and column 0.

[0090] Specifically, step S301: Start scanning.

[0091] Step S302: Within the first time period, determine the sub-pixel in row 0, column 0. The sub-pixel in row 0, column 0, is... Figure 2 The first sub-pixel in the first pixel group in the top left corner is scanned (the red regular sub-pixel in the illustration).

[0092] Step S303: Determine whether it is within the first time period of the time sequence. If yes, proceed to step S304; otherwise, proceed to step S311.

[0093] Since it is within the first time period, step S304 is executed.

[0094] Step S304: Determine whether the value of the position point corresponding to the pixel group to which the sub-pixel belongs is 1. If yes, proceed to step S305; otherwise, proceed to step S306.

[0095] If the value of the position point corresponding to the pixel group is 1, then step S305 is executed, based on the CPA matrix diagram corresponding to the display screen.

[0096] Step S305: The gray level is the gray level of the target image data corresponding to this sub-pixel.

[0097] Step S306: The grayscale is 0 grayscale.

[0098] Step S307: Determine whether the column number of the sub-pixel is (V-1). If yes, proceed to step S309; ​​otherwise, proceed to step S308.

[0099] Determine whether the column number of the sub-pixel is (V-1), that is, determine whether the sub-pixel is located in the last column of the row. Since the sub-pixel is not in the last column, proceed to step S308.

[0100] It is worth noting that the sub-pixel in row 0, column 1 is the first sub-pixel in the second pixel group (the green regular sub-pixel in the illustration), the sub-pixel in row 0, column 2 is the first sub-pixel in the third pixel group (the blue regular sub-pixel in the illustration), and the sub-pixel in row 0, column (V-1) is the last first sub-pixel in row 0.

[0101] Step S308: Scan (column number + 1) sub-pixels and execute step S304.

[0102] That is, scan the sub-pixel of row 0, column 1, which is to scan the first sub-pixel in the second pixel group, and then repeat step S304. Until the last column of row 0 is scanned, that is, the (V-1)th column of row 0, execute step S309.

[0103] Step S309: Determine whether the number of rows of the sub-pixel is equal to (H-1). If yes, proceed to step S316. If no, proceed to step S310.

[0104] Step S316: Proceed to the next time period and execute step S303.

[0105] Step S310: Scan the sub-pixels with (row number + 1) column number of 0, and execute step S304.

[0106] The process involves determining whether the number of rows of the sub-pixel is equal to (H-1), which means determining whether the sub-pixel is located in the last column of the last row. If it is, the process proceeds to the next time period, and step S316 is executed. If not, the process scans the sub-pixel in the 0th column of the next row.

[0107] Step S311: Is the value of the position point corresponding to the pixel group to which the sub-pixel belongs 1? If yes, proceed to step S312; otherwise, proceed to step S313.

[0108] Step S312: The grayscale is 0 grayscale.

[0109] Step S313: The gray level is the gray level of the target image data corresponding to this sub-pixel.

[0110] Combining steps S303-S306 and S311-S313, for a regular sub-pixel, when the value of the position point corresponding to its pixel group is 1, the pixel group is in non-spy mode, and the gray level of the regular sub-pixel is equal to the gray level of the corresponding target image data; when the value of the position point corresponding to its pixel group is not 1, the pixel group is in spy mode, and the gray level of the regular sub-pixel is equal to 0 gray level, that is, the regular sub-pixel does not emit light. For a spy sub-pixel, when the value of the position point corresponding to its pixel group is 1, the pixel group is in non-spy mode, and the gray level of the spy sub-pixel is equal to 0 gray level, that is, it does not emit light; when the value of the position point corresponding to its pixel group is not 1, the pixel group is in spy mode, and the gray level of the spy sub-pixel is equal to the gray level of the corresponding target image data.

[0111] Step S314: Is the column number of the sub-pixel (V-1)? If yes, proceed to step S309; ​​otherwise, proceed to step S315.

[0112] Determine if the column number of the sub-pixel is (V-1), that is, determine if the sub-pixel is located in the last column of the row.

[0113] Step S315: Scan (column number + 1) sub-pixels and execute step S311.

[0114] Figure 13 This is a schematic diagram illustrating the process of determining sub-pixel gray levels, provided as another embodiment of this application. Figure 13 As shown, the grayscale of each sub-pixel is determined starting from row 0 and column 0.

[0115] by Figure 6 Taking the first and second pixel groups in the upper left corner as an example, in the first pixel group, the first sub-pixel is in row 0 and the second sub-pixel is in row 1; in the second pixel group, the first sub-pixel is in row 2 and the second sub-pixel is in row 3. Therefore, in this embodiment, all first sub-pixels are located in even-numbered rows, and all second sub-pixels are located in odd-numbered rows. Furthermore, the first and second sub-pixels in each pixel group need to be scanned through two rows. The display panel has V pixel units in the row direction and H pixel units in the column direction. Therefore, according to the above scanning method, a total of 2H rows and V columns are scanned. Specifically, step S401: Start scanning.

[0116] Step S402: Determine the sub-pixel in row 0, column 0. That is, scan the sub-pixel in row 0, column 0, i.e., for... Figure 6 The first sub-pixel in the first pixel group in the top left corner is scanned (the red regular sub-pixel in the illustration).

[0117] Step S403: Determine if the row number of the sub-pixel divided by 2 leaves a remainder of 0. If yes, proceed to step S404; otherwise, proceed to step S411.

[0118] The number of rows for this sub-pixel is 0, therefore step S404 is executed.

[0119] Step S404: Determine whether the value of the position point corresponding to the pixel group to which the sub-pixel belongs is 1. If yes, proceed to step S405; otherwise, proceed to step S406.

[0120] If the value of the position point corresponding to the pixel group is 1, then step S405 is executed, based on the CPA matrix diagram corresponding to the display screen.

[0121] Step S405: The gray level is the gray level of the target image data corresponding to this sub-pixel.

[0122] Step S406: The grayscale is 0 grayscale.

[0123] Step S407: Determine whether the column number of the sub-pixel is (V-1). If yes, proceed to step S409; otherwise, proceed to step S408.

[0124] Determine whether the column number of the sub-pixel is (V-1), that is, determine whether the sub-pixel is located in the last column of the row. Since the sub-pixel is not in the last column, proceed to step S408.

[0125] It is worth noting that the sub-pixel in row 0, column 1 is the second sub-pixel in the first pixel group (the red privacy sub-pixel in the illustration), the sub-pixel in row 0, column 2 is the first sub-pixel in the second pixel group (the green regular sub-pixel in the illustration), and the sub-pixel in row 0, column (V-1) is the last second sub-pixel in row 0.

[0126] Step S408: Scan (column number + 1) sub-pixels and execute step S304.

[0127] Continue scanning until the last column of row 0 is scanned, i.e., the (V-1)th column of row 0, then proceed to step S409.

[0128] Step S409: Determine whether the number of rows of the sub-pixel is equal to (2H-1). If yes, proceed to step S416. If no, proceed to step S410.

[0129] Step S316: End scan.

[0130] Step S410: Scan the sub-pixels with (row number + 1) column number of 0, and execute step S403.

[0131] Since the two sub-pixels in a pixel group belong to two different rows, a total of 2H rows are scanned. It is then determined whether the row number of the sub-pixel is equal to (2H-1), that is, whether the sub-pixel is located in the last column of the last row. If yes, the scanning of all sub-pixels in the entire display screen is completed, and step S416 is executed; otherwise, the sub-pixels in the 0th column of the next row are scanned.

[0132] Step S411: Is the value of the position point corresponding to the pixel group to which the sub-pixel belongs 1? If yes, proceed to step S412; otherwise, proceed to step S413.

[0133] Step S412: The gray level is 0 gray level.

[0134] Step S413: The gray level is the gray level of the target image data corresponding to this sub-pixel.

[0135] Combining steps S403-S406 and S411-S413, when the row number divided by 2 equals 0, it indicates that the sub-pixel is in an even-numbered row, meaning it is the first sub-pixel. When the row number divided by 2 is not 0, it indicates that the sub-pixel is in an odd-numbered row, meaning it is the second sub-pixel. For regular sub-pixels, when the value of the position point corresponding to their pixel group is 1, the pixel group is in non-spy mode, and the grayscale of the regular sub-pixel is equal to the grayscale of the corresponding target image data. When the value of the position point corresponding to their pixel group is not 1, the pixel group is in spy mode, and the grayscale of the regular sub-pixel is equal to 0 grayscale, meaning the regular sub-pixel does not emit light. For a privacy sub-pixel, when the value of the position point corresponding to its pixel group is 1, the pixel group is in non-privacy mode, and the gray level of the privacy sub-pixel is equal to 0 gray level, that is, it does not emit light; when the value of the position point corresponding to its pixel group is not 1, the pixel group is in privacy mode, and the gray level of the privacy sub-pixel is equal to the gray level of the corresponding target image data.

[0136] Step S414: Is the column number of the sub-pixel (V-1)? If yes, proceed to step S409; otherwise, proceed to step S415.

[0137] Determine if the column number of the sub-pixel is (V-1), that is, determine if the sub-pixel is located in the last column of the row.

[0138] Step S415: Scan (column number + 1) sub-pixels and execute step S411.

[0139] In some embodiments, the driving module includes a first storage submodule and a second storage submodule, and acquires target image data and a privacy protection area control matrix, including: the first storage submodule acquires target image data and a privacy protection area control matrix within a first time period; and the second storage submodule acquires target image data and a privacy protection area control matrix within a second time period.

[0140] In this embodiment, both the first and second storage submodules can store target image data for two time periods, i.e., receiving target image data for one time period while processing target image data for another time period. The first and second storage submodules employ a ping-pong operation, meaning that while one receives target image data, the other processes the target image data and outputs a digital signal. This application allows the privacy protection area to be changed at any time according to user needs. The ping-pong operation between the first and second storage submodules for storing target image data facilitates data retrieval and avoids lag.

[0141] In some embodiments, step S103, based on the grayscale of each of the multiple sub-pixels included in each pixel group, controls the display panel to display, including: determining the data voltage corresponding to each of the multiple sub-pixels included in each pixel group based on the grayscale of each of the multiple sub-pixels included in each pixel group; controlling the driving module to input the data voltage corresponding to each of the multiple sub-pixels included in each pixel group into the multiple sub-pixels included in each pixel group; and controlling the display panel to display based on the data voltage corresponding to each of the multiple sub-pixels included in each pixel group.

[0142] In some embodiments, each pixel group includes a plurality of sub-pixels, including a first sub-pixel and a second sub-pixel.
