[0045] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0046] The display control method of the display screen in this application embodiment has two sets of gamma curve data pre-set in the register of the display screen. Each set of gamma curve data corresponds to a display mode. The display screen can call the corresponding gamma curve data for matching output according to the required display mode to switch to different display modes.

[0047] An embodiment of this application provides a display control method for a display screen, such as... Figure 1 As shown, the method includes:

[0048] S100, based on the first correspondence between the grayscale information represented by the first gamma curve data of the display screen and the power parameters, determine the first power parameters corresponding to the target grayscale;

[0049] In this embodiment, if the required display mode is a first display mode, the display will call the first gamma curve data corresponding to the first display mode. The first gamma curve data represents the first correspondence between grayscale information and power parameters. Specifically, the first gamma curve data is the first anchoring relationship between the grayscale information input by the system and the output voltage / current of the display. After the system inputs the target grayscale, it sends the target grayscale to the display. After receiving the target grayscale, the display can determine the first power parameter corresponding to the target grayscale based on the first correspondence between the grayscale information and power parameters represented by the first gamma curve data. For example, based on the first correspondence between the grayscale information and power parameters represented by the first gamma curve data, the power parameter anchored for the minimum grayscale is the minimum voltage / current value of the display, and the power parameter anchored for the maximum grayscale is the maximum operating voltage / current value of the display.

[0050] S200, based on the first power parameter, determine the first contrast ratio of the display screen, wherein the first display mode corresponding to the first contrast ratio has a first viewing angle;

[0051] In this embodiment, after determining the first power parameter corresponding to the target grayscale based on the first correspondence between the grayscale information represented by the first gamma curve data of the display screen and the power parameters, the first contrast ratio of the display screen is determined based on the first power parameter. Specifically, after determining the operating voltage / current output by the display screen based on the first gamma curve data, the first contrast ratio of the display screen can be determined based on the operating voltage / current output by the display screen. The first contrast ratio corresponds to a first display mode, and the first display mode corresponding to the first contrast ratio has a first viewing angle. The first contrast ratio is a high contrast ratio, the first display mode is a sharing mode, and the first viewing angle corresponding to the first display mode is relatively wide. Under the first viewing angle of the first display mode, the user can view the entire content of the display screen.

[0052] S300, upon receiving an instruction to switch the display mode of the display screen, the second power parameter corresponding to the target gray level is determined based on the second correspondence between the gray level information represented by the second gamma curve data of the display screen and the power parameter, wherein the numerical range of the power parameter represented by the second correspondence is within the numerical range of the power parameter represented by the first correspondence.

[0053] In this embodiment, upon receiving an instruction to switch the display mode, indicating that the display is switching from the current first display mode to the second display mode, the display will call the second gamma curve data corresponding to the second display mode. The second gamma curve data represents a second correspondence between grayscale information and power parameters, and the numerical range of the power parameters represented by the second correspondence is within the numerical range of the power parameters represented by the first correspondence. Specifically, the second gamma curve data is a second anchoring relationship between the grayscale information input by the system and the output voltage / current of the display. After the system inputs the target grayscale, it sends the target grayscale to the display. After receiving the target grayscale, the display can determine the second power parameter corresponding to the target grayscale based on the second correspondence between the grayscale information and power parameters represented by the second gamma curve data. For example, based on the second correspondence between the grayscale information and power parameters represented by the second gamma curve data, the numerical range of the power parameter anchored by the minimum grayscale is between the minimum voltage / current value and 1 / 10 of the maximum operating voltage / current value of the display, and the power parameter anchored by the maximum grayscale is the maximum operating voltage / current value of the display.

[0054] S400, based on the second power parameter, determine the second contrast ratio of the display screen, wherein the second contrast ratio corresponds to a second display mode with a second viewing angle, and the second viewing angle is smaller than the first viewing angle.

[0055] In this embodiment, after determining the second power parameter corresponding to the target grayscale based on the second correspondence between the grayscale information represented by the second gamma curve data of the display screen and the power parameters, the second contrast ratio of the display screen is determined based on the second power parameter. Specifically, after determining the operating voltage / current output by the display screen based on the second gamma curve data, the second contrast ratio of the display screen can be determined based on the operating voltage / current output by the display screen. The second contrast ratio corresponds to a second display mode, and the second display mode corresponding to the second contrast ratio has a second viewing angle. The second contrast ratio is a low contrast ratio, the second display mode is a privacy mode, and the second viewing angle corresponding to the second display mode is relatively narrow. Under the second viewing angle of the second display mode, the user can only view the entire content of the display screen within a certain range of viewing angles.

[0056] This application, through the aforementioned method, pre-sets two sets of gamma curve data in the display's register. If the required display mode is sharing mode, the first gamma curve data is called, and a first power parameter corresponding to the target grayscale is determined based on the first gamma curve data. Then, a higher first contrast ratio is determined based on the first power parameter. The first contrast ratio corresponds to sharing mode, which has a wider first viewing angle, allowing the user to view the entire content of the display screen. Upon receiving an instruction to switch the display mode, the display calls the second gamma curve data, and a second power parameter corresponding to the target grayscale is determined based on the second gamma curve data. Then, a lower second contrast ratio is determined based on the second power parameter. The second contrast ratio corresponds to privacy mode, which has a narrower second viewing angle, allowing the user to view the entire content of the display screen only within a certain range of angles, thus achieving a privacy effect. This application calls the corresponding gamma curve data based on the required display mode, determines the contrast ratio based on the gamma curve data, and then determines the corresponding display mode, thereby controlling and switching between sharing mode and privacy mode, achieving a display privacy effect.

[0057] In one embodiment of this application, determining the first power parameter corresponding to the target gray level based on the first correspondence between the gray level information represented by the first gamma curve data of the display screen and the power parameter includes:

[0058] Based on the correspondence between grayscale information and voltage represented by the first correspondence, the first output voltage corresponding to the target grayscale is obtained.

[0059] In this embodiment, after the display receives the target grayscale, it can determine the first power parameter corresponding to the target grayscale based on the first correspondence between the grayscale information represented by the first gamma curve data and the power parameters. Specifically, the first output voltage corresponding to the target grayscale can be obtained based on the correspondence between the grayscale information represented by the first correspondence and the voltage. For example, based on the correspondence between the grayscale information represented by the first correspondence and the voltage, the voltage anchored to the minimum grayscale is the minimum voltage value of the display screen, the minimum grayscale is 0 grayscale, and the minimum voltage value is 0V; the voltage anchored to the maximum grayscale is the maximum operating voltage value of the display screen, and the maximum grayscale is 255 grayscale.

[0060] In one embodiment of this application, such as Figure 2 As shown, determining the first contrast ratio of the display screen based on the first power parameter includes:

[0061] S210, based on the first output voltage corresponding to the target grayscale, obtain the first display brightness of the display screen;

[0062] In this embodiment, after obtaining the first output voltage corresponding to the target grayscale based on the correspondence between grayscale information and voltage represented by the first correspondence, the first display brightness of the display screen can be obtained based on the first output voltage corresponding to the target grayscale. Specifically, after receiving the target grayscale data sent by the system and obtaining the first output voltage corresponding to the target grayscale, the display brightness of the pixel can be determined by controlling the voltage applied to the liquid crystal on the display screen, controlling the rotation angle of the liquid crystal, and thus controlling the amount of backlight emitted from the display screen. That is, the output voltage corresponding to the grayscale is directly related to the brightness. Since the first gamma curve data of the display screen represents the first correspondence between grayscale information and power parameters, the first gamma curve data further represents the correspondence between grayscale information and brightness. Figure 4 As shown, based on the correspondence between grayscale information and brightness represented by the first gamma curve data of the display screen, the first display brightness value corresponding to the target grayscale can be determined.

[0063] S220, based on the first display brightness, determine the first contrast ratio of the display screen.

[0064] In this embodiment, after obtaining the first display brightness of the display screen based on the first output voltage corresponding to the target grayscale, the first contrast ratio of the display screen can be determined based on the first display brightness. Specifically, as shown... Figure 5 As shown, the minimum display brightness of the display can be determined based on the minimum voltage value of the display, and the maximum display brightness of the display can be determined based on the maximum operating voltage value of the display. The contrast ratio of the display is the ratio of the maximum display brightness to the minimum display brightness of the display. The first contrast ratio of the display in the first display mode is a relatively high contrast ratio.

[0065] In one embodiment of this application, determining the second power parameter corresponding to the target grayscale based on the second correspondence between the grayscale information represented by the second gamma curve data of the display screen and the power parameter includes:

[0066] Based on the correspondence between the grayscale information and voltage represented by the second correspondence, the second output voltage corresponding to the target grayscale is obtained, wherein the second output voltage is greater than the first output voltage corresponding to the target grayscale.

[0067] In this embodiment, after the display receives the target grayscale, it can determine the second power parameter corresponding to the target grayscale based on the second correspondence between the grayscale information represented by the second gamma curve data and the power parameters. Specifically, the second output voltage corresponding to the target grayscale can be obtained based on the correspondence between the grayscale information and the voltage represented by the second correspondence. For example, based on the correspondence between the grayscale information and the voltage represented by the second correspondence, the voltage value anchored to the minimum grayscale is within the range of the minimum voltage value of the display screen and 1 / 10 of the maximum operating voltage value, the minimum grayscale is 0 grayscale, and the minimum voltage value is 0V; the voltage anchored to the maximum grayscale is the maximum operating voltage value of the display screen, the maximum grayscale is 255 grayscale, and the second output voltage is greater than the first output voltage corresponding to the target grayscale.

[0068] In one embodiment of this application, such as Figure 3 As shown, determining the second contrast ratio of the display screen based on the second electrical parameter includes:

[0069] S410, based on the second output voltage corresponding to the target grayscale, obtain the second display brightness of the display screen;

[0070] In this embodiment, after obtaining the second output voltage corresponding to the target grayscale based on the correspondence between grayscale information and voltage represented by the second correspondence, the second display brightness of the display screen can be obtained based on the second output voltage corresponding to the target grayscale. Specifically, after receiving the target grayscale data sent by the system and obtaining the second output voltage corresponding to the target grayscale, the display brightness of the pixel can be determined by controlling the voltage applied to the liquid crystal on the display screen, controlling the rotation angle of the liquid crystal, and thus controlling the amount of backlight emitted from the display screen. That is, the output voltage corresponding to the grayscale is directly related to the brightness. Since the second gamma curve data of the display screen represents the second correspondence between grayscale information and power parameters, the second gamma curve data further represents the correspondence between grayscale information and brightness. Figure 4 As shown, based on the correspondence between grayscale information and brightness represented by the second gamma curve data of the display screen, the second display brightness value corresponding to the target grayscale can be determined. Since the second output voltage is greater than the first output voltage corresponding to the target grayscale, the second display brightness value is greater than the first display brightness value.

[0071] S420, based on the second display brightness, determine the second contrast ratio of the display screen, wherein the second contrast ratio is less than the first contrast ratio of the display screen.

[0072] In this embodiment, after obtaining the second display brightness of the display screen based on the second output voltage corresponding to the target grayscale, the second contrast ratio of the display screen can be determined based on the second display brightness. Specifically, as shown... Figure 5As shown, the minimum display brightness of the display can be determined based on the minimum voltage value of the display, and the maximum display brightness of the display can be determined based on the maximum operating voltage value of the display. The contrast ratio of the display is the ratio of the maximum display brightness to the minimum display brightness. In the second display mode, the minimum voltage value of the display is higher than that of the first display mode, and the minimum display brightness of the display in the second display mode is also higher than that of the first display mode. Therefore, the second contrast ratio of the display is lower than that of the first contrast ratio of the first display mode.

[0073] In one embodiment of this application, the method further includes:

[0074] Based on the control signal for switching display modes, the first gamma curve data or the second gamma curve data is invoked to match and output the target grayscale data, so as to switch to the corresponding display mode, which includes sharing mode and privacy mode.

[0075] In this embodiment, upon receiving a control signal to switch display modes, the system invokes either the first gamma curve data or the second gamma curve data based on the control signal to match and output the target grayscale data, thereby switching to the corresponding display mode. Specifically, when switching from sharing mode to privacy mode, the system invokes the second gamma curve data corresponding to the privacy mode and matches and outputs the target grayscale data based on the second gamma curve data to switch to privacy mode. Alternatively, when switching from privacy mode to sharing mode, the system invokes the first gamma curve data corresponding to the sharing mode and matches and outputs the target grayscale data based on the first gamma curve data to switch to sharing mode.

[0076] In one specific embodiment of this application, after receiving an instruction to switch the display mode of the screen from sharing mode to privacy mode, the screen will call the second gamma curve data corresponding to the privacy display mode. The gamma value of the overall curve can be a common 2.2, and the viewing angle of the screen will change. Specifically, as... Figure 6 As shown, the viewing angle of a display screen is based on the screen's normal. When the viewing angle and the screen's normal are at a certain angle θ, the contrast ratio drops to 10. When the contrast ratio drops below 10, the human eye can hardly distinguish the content on the screen. The angle θ is the screen's viewing angle. The two parameters θ in the figure... x and θ yThe viewing angles along the horizontal x and y directions of the screen are defined, with the plus or minus sign indicating the angle between the x and y axes and the normal, which is a vertical line located in the center of the display screen. As the angle between the viewing angle and the normal increases, the maximum brightness corresponding to the highest grayscale level of the display screen decreases rapidly, causing the contrast ratio of the display screen to decrease rapidly, thus achieving the privacy protection effect.

[0077] In one embodiment of this application, the display mode switching method includes at least one of the following:

[0078] The display mode can be switched by issuing commands via keyboard shortcuts, via software-defined options, or by clicking with the mouse.

[0079] In this embodiment, the display mode can be switched using at least one of the following methods: issuing a command to switch the display mode via a keyboard shortcut, issuing a command to switch the display mode via a software-defined option, or controlling the switching of the display mode by clicking with a mouse. Switching the display mode using any of these methods requires the system to send the switching command to the display screen via a wiring channel. After receiving the command, the display screen switches between the first gamma curve data and the second gamma curve data according to the current command.

[0080] Based on the same inventive concept, the second aspect of this application also provides an electronic device corresponding to the display control method of the display screen. Since the principle of solving the problem by the electronic device in this application is similar to the above-mentioned processing method, the implementation of the electronic device can refer to the implementation of the method, and the repeated parts will not be described again.
