[0002] In the related art, displays on mobile electronic devices, such as active-matrix organic light-emitting diode (AMOLED) displays, experience color shifts, such as green or purple, when viewing the edges of the display panel due to differences in light paths between the edges and center areas. To mitigate this edge color shift, an edge bending compensation (EBC) function is typically implemented in the display driver integrated circuit (DDIC).

However, the user's usage habits are constantly changing, and the angle at which the user views the screen will also change. When the user views the screen at an angle other than the direct viewing angle, the user will still observe color deviation at the edge of the screen, resulting in poor display effect of the electronic device.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The display control method and device of an electronic device, the electronic device, and the storage medium provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] In some embodiments of the present application, a display control method for an electronic device is provided. The electronic device includes a display panel. Figure 1 Schematic diagram showing the display area of ​​the display panel of some embodiments of the present application, such as Figure 1 As shown, the display panel 100 includes a first display area 102, and the first display area 102 includes N display units 104, and the N display units are evenly distributed in the first display area, wherein the N display units include M target display units and non-target display units other than the M target display units, and N and M are both positive integers.

[0034] Figure 2 A flow chart showing a display control method of an electronic device according to some embodiments of the present application is shown. Figure 2 As shown, the display control method includes:

[0035] Step 202: Acquire posture information and viewing angle information of the electronic device, and determine M target display units among N display units.

[0036] In the embodiments of the present application, electronic devices include, but are not limited to, mobile phones, tablet computers, smart watches, smart bracelets, and other electronic devices. The electronic devices include a display panel, which may be an AMOLED display panel, a sub-millimeter light-emitting diode (Mini-LED) display panel, or the like.

[0037] The display panel includes N display units. Exemplarily, a display unit may include one pixel or multiple pixels. Exemplarily, the target display unit is a preset display unit that is pre-calibrated among the N display units during the production of the display panel. Exemplarily, the M target display units may also be randomly selected from the N display units. Exemplarily, after the M target display units are determined, all display units other than the M target display units in the N display units are defined as non-target display units, and the number of non-target display units is (NM).

[0038] When an electronic device displays content, the device's posture information and the user's viewing angle information are acquired in real time. The electronic device's posture information specifically includes the angle between the plane on which the electronic device's display panel resides and the horizontal plane. The user's viewing angle information specifically includes the angle between the line connecting the user's eyes and the object being looked at on the screen and the display panel.

[0039] Step 204 : Determine the equivalent color coordinates of each target display unit according to the posture information and the viewing angle information, and obtain M equivalent color coordinates.

[0040] In the embodiment of the present application, the first display area is specifically a pre-set display area that needs to be color compensated (or edge bending area compensation). For example, the first display area can be the edge area of ​​the display panel. For example, Figure 1 As shown, the first display area 102 is located at the edge area of ​​the display panel 100 .

[0041] Figure 3 Schematic diagram showing the display area of ​​the display panel of some embodiments of the present application, such as Figure 3 As shown, the first display area 102 includes a target display unit 1042 and a non-target display unit 1044 , wherein the target display unit 1042 is a pre-selected display unit.

[0042] Exemplarily, the electronic device stores actual color coordinates of the target display unit under different posture information and different viewing angle information, and determines the equivalent color coordinates of the target display unit according to the actual color coordinates and the standard color coordinates under the normal viewing angle.

[0043] Step 206 : Determine the first color compensation value of each target display unit according to each of the M equivalent color coordinates, and obtain M first color compensation values.

[0044] In an embodiment of the present application, the equivalent color coordinates are specifically the color coordinates that can make the color of the target display unit in the eyes of the user consistent with the color actually required to be displayed under the posture information of the current electronic device and the current user perspective. Based on the difference between the equivalent color coordinates and the color coordinate table of the color actually required to be displayed, a first color compensation value can be obtained. By compensating the initial color coordinates of the target display unit with the first color compensation value, the effect of making the color of the target display unit in the eyes of the user consistent with the color actually required to be displayed can be obtained.

[0045] Step 208, determining a second color compensation value for each non-target display unit according to the M first color compensation values;

[0046] Among them, such as Figure 3 As shown, the non-target display unit 1044 includes other display units among the N display units 104 except the target display unit 1042 .

[0047] In the embodiment of the present application, the first display area of ​​the display panel includes N display units, where a larger number of N indicates more accurate color compensation. However, as the number of display units requiring color compensation increases, more compensation work must be performed at the factory, resulting in lower efficiency.

[0048] In order to improve efficiency, the present application predetermines M target display units among all N display units that require color compensation, and calibrates the equivalent color coordinates of these M target display units under different posture information and different viewing angle information.

[0049] When the user actually uses the electronic device, the posture information and viewing angle information are collected in real time. Through the posture information and viewing angle information collected in real time, the M first color compensation values ​​of the above-mentioned M target display units are determined in real time. Since the optical path of the display panel is basically fixed, the color deviation of the display units at different positions also changes approximately linearly with the changes in information such as angle and distance.

[0050] Therefore, among the N display units, the other display units except the M target display units are defined as non-target display units, and the equivalent viewing angle is determined based on the relative positional relationship between each non-target display unit, the target display unit and the human eye, through the posture information and viewing angle information captured by the sensor, and the second color compensation value of each non-target display unit is obtained based on linear interpolation, so that dynamic color compensation can be achieved for each display unit without the need for pre-compensation of each display unit.

[0051] Step 210 : Controlling the display panel to display content based on the first color compensation value and the second color compensation value.

[0052] In an embodiment of the present application, after compensating the brightness of the R (red), G (green), and B (blue) sub-pixels in the target display unit by using the first color compensation value, and compensating the brightness of the R, G, and B sub-pixels in the non-target display unit by using the second color compensation value, all pixels on the display panel reflect the correct colors in the human eye.

[0053] The present application obtains the posture information of the current electronic device and the viewing angle information of the user currently viewing the display panel of the electronic device in real time when the electronic device displays content, and combines the posture information of the electronic device and the viewing angle information of the user to perform color compensation on the display unit in the first display area where the display panel is prone to color cast. Therefore, no matter what posture or viewing angle the user uses to view the display panel of the electronic device, targeted color compensation can be performed to avoid the problem of color cast at the edge of the screen when the user views the screen at a non-normal viewing angle, thereby improving the display effect of the electronic device.

[0054] In some embodiments of the present application, before acquiring the posture information of the electronic device and the viewing angle information of the user, the display control method further includes:

[0055] According to the parameter information of the display panel, a first display area and a second display area are determined within the display area of ​​the display panel; wherein the second display area is located at the center of the display panel, the first display area is located on the periphery of the second display area, and M target display units are distributed along the circumference of the second display area.

[0056] In an embodiment of the present application, the parameter information of the display panel determines the actual color deviation under different user viewing angles when the display panel is in different posture information. Through the display panel parameter information, the area that needs color compensation can be determined on a display panel, that is, the above-mentioned first display area. The second display area is the area that does not need color compensation. Generally speaking, the second display area is the central area of ​​the display panel, which is the area viewed by the user at the normal viewing angle in most cases. The first display area is the edge area of ​​the display panel. When the user views the display content of the display panel, the color of the display unit in the first display area may be deviated due to the influence of light path differences and other factors.

[0057] For example, Figure 1 and Figure 3 As shown, the second display area 106 is located at the center of the display panel 100 , and the first display area 102 is located at the edge area of ​​the display panel 100 and around the second display area 106 .

[0058] In order to quickly obtain the color compensation value of each display unit in the first display area 102, a plurality of target display units 1042 are arranged at intervals in the first display area 102, specifically in the circumference of the second display area 106, so that one or more adjacent target display units 1042 can always be found near each non-target display unit 1044 in the first display area 102, and then the second color compensation value of each non-target display unit 1044 is obtained by linear fitting based on the changing trend of the first color compensation values ​​of these target display units 1042, thereby performing color compensation on all display units 104 in the first display area 102.

[0059] The present application divides the first display area that needs color compensation and sets a number of target display units that perform color compensation in advance in the first display area, thereby improving the efficiency of color compensation while ensuring the accuracy and reliability of color compensation.

[0060] In some embodiments of the present application, before acquiring the posture information of the electronic device and the viewing angle information of the user, the display control method further includes:

[0061] Obtain color coordinate information of M target display units; wherein the color coordinate information includes the association between the actual color coordinates of each target display unit and spatial information; the spatial information includes: the distance between each target display unit and the center point of the display panel, the correspondence between each target display unit and the posture information, and the correspondence between each target display unit and the viewing angle information; obtain the orthographic color coordinates of the M target display units; and determine the equivalent color coordinates of each target display unit based on the color coordinate information, the orthographic color coordinates, and the color deviation trajectory parameters of the second display area.

[0062] In an embodiment of the present application, when producing and calibrating a display panel, based on the parameter information of the display panel, a first display area that requires color compensation is determined within the entire display area of ​​the display panel, and a number of target display units are pre-set within the first display area, and the equivalent color coordinates of these target display units are calibrated. The equivalent color coordinates are specifically the actual color coordinates of the target display unit when the display panel is in different posture information and different user viewing angle information.

[0063] Exemplarily, the display panel is controlled to display different colors, and the actual color coordinates of the target display unit are collected under different posture information and different viewing angle information, and the collected actual color coordinates are mapped and stored with the posture information and viewing angle information to obtain the above-mentioned color coordinate information.

[0064] Obtaining the color coordinates of the display panel at a normal viewing angle when displaying different colors to obtain the normal viewing color coordinates. The normal viewing color coordinates are specifically the color coordinates of the target display unit in the user's eyes when the display panel is located on a horizontal plane and the user looks directly at the target display unit at a vertical angle.

[0065] For example, Figure 4 A schematic diagram of the color deviation trajectory of some embodiments of the present application is shown. The difference between the orthographic color coordinates obtained in the above steps and the actual color coordinates can reflect the "color deviation" of a target display unit under different posture information and different viewing angle information. Combined with the color deviation trajectory calibrated during the production of the display panel, the above-mentioned "equivalent coordinates" can be obtained.

[0066] The color shift trajectory specifically refers to the trajectory of the color coordinates of the second display area at different viewing angles. This trajectory reflects the color of the display panel as viewed by the user at different viewing angles. This color shift trajectory is determined by camera capture during panel parameter calibration. Because the first display area is at the edge of the display panel, there are arc angles at the edge, which can lead to inaccurate colors captured by the camera. Therefore, the second display area in the center is used to capture the color shift trajectory.

[0067] For example, the color deviation trajectory of the second display area is first tested to obtain a curve of the color coordinates at different viewing angles relative to the color coordinate origin. This curve is the curve of the color deviation trajectory described above. Then, the target display unit is calibrated in the first display area, and the color coordinates of the target display unit and the user's actual "posture viewing angle" are measured. That is, the posture viewing angle and the color coordinate 1. By comparing the color coordinate 0 and the color coordinate 1, the mapping relationship between the "posture viewing angle" of the first display area and the "different viewing angles" of the second display area is obtained. That is, the "posture viewing angle" of the first display area is converted into a known viewing angle of the second display area, which is defined here as the "equivalent viewing angle."

[0068] After the equivalent viewing angle is determined, the grayscale values ​​of red, green, and blue that need to be compensated, that is, the color values ​​(RGB values), are determined according to the “color shift trajectory” of the second display area.

[0069] The target display unit in the first display area can be tested and determined during the development of the display panel according to the above process. Then, the other N-display units in the first display area are calculated by the interpolation algorithm through the application processor (AP) or the microcontroller unit (MCU) in the display driver integrated circuit (DDIC) to achieve real-time and dynamic color compensation. For example, Figure 5 A schematic diagram showing spatial information in some embodiments of the present application is shown in FIG. Figure 5 As shown, the equivalent coordinate is defined as K, then K = (L, α, β). Where L is the straight-line distance between the target display unit 1042 and the center point O of the display panel, α is the aforementioned posture information, that is, the angle between the display panel and the horizontal plane, and β is the aforementioned viewing angle information, that is, the angle between the user's eyes and the screen.

[0070] The present application sets a target display unit in an area where color compensation is required, and calibrates the color coordinate information of the target display unit, so that when a user uses an electronic device, the electronic device can determine a first color compensation value of the target display unit based on posture information and viewing angle information collected in real time, and obtain a second color compensation value for all display units that require color steps based on the first color compensation value, and perform color compensation on the display content of the display panel, which can improve the display effect of the electronic device.

[0071] In some embodiments of the present application, determining the second color compensation value of each non-target display unit according to the M first color compensation values ​​includes:

[0072] Obtaining a positional relationship between each non-target display unit and M target display units, wherein the positional relationship includes a distance between a non-target display unit and each target display unit; and determining a second color compensation value for each non-target display unit based on an interpolation algorithm, the positional relationship between each non-target display unit and the M target display units, and the M first color compensation values.

[0073] In an embodiment of the present application, after obtaining M first color compensation values ​​corresponding to M target display units, based on the positional relationship between each non-target display unit and the known target display unit, an interpolation algorithm is used to fit the second color compensation value of each non-target display unit, thereby accurately color compensating all N display units in the first display area.

[0074] For example, assuming there are 10 target display units, when determining the second color compensation value of each non-target display unit, there is a certain positional relationship between this non-target display unit and the 10 known target display units. The positional relationship includes the distance between the current non-target display unit and each target unit, and the relative position of the current non-target display unit within the 10 target display units.

[0075] A proportional relationship is determined based on the distance between the non-target display unit and the 10 target display units, thereby obtaining a second color compensation value of the non-target display unit.

[0076] The present application obtains the second color compensation values ​​of all other non-target display units by fitting the first color compensation values ​​of several known target display units, thereby improving the efficiency of color compensation.

[0077] In some embodiments of the present application, the electronic device also includes a posture sensor, an application processor and a display driver chip, and the display driver chip includes a color compensation circuit; wherein the posture sensor is used to obtain posture information and send the posture information to the application processor, and the posture information is sent to the display driver chip through the application processor.

[0078] Determining the equivalent color coordinates of each target display unit according to the posture information and the viewing angle information to obtain M equivalent color coordinates includes: controlling the application processor to determine the equivalent color coordinates of each target display unit according to the posture information and the viewing angle information to obtain M equivalent color coordinates.

[0079] Determining a first color compensation value for each target display unit according to each equivalent color coordinate of M equivalent color coordinates to obtain M first color compensation values ​​includes: controlling a color compensation circuit to determine the first color compensation value for each target display unit according to each equivalent color coordinate of M equivalent color coordinates to obtain M first color compensation values.

[0080] In the embodiments of this application, Figure 6 Schematic diagrams showing the structure of electronic devices in some embodiments of the present application are shown. Figure 6 As shown, the electronic device includes a posture sensor, exemplarily comprising a spirit level or a gyroscope. The electronic device also includes an application processor (AP) and a display driver integrated circuit (DDIC). The display driver integrated circuit (DDIC) includes a hardware color compensation circuit (EBC). In other feasible implementations, the color compensation circuit (EBC) may also be integrated into the application processor (AP) or into another chip.

[0081] When an electronic device is working, the posture sensor obtains the posture information of the current electronic device and detects the user's viewing angle information through the front camera or other sensors. This information is sent to the application processor AP. The application processor AP determines the equivalent color coordinates of the target display unit based on the received posture information and viewing angle information.

[0082] The color compensation circuit EBC can be linked with a linear interpolation algorithm or a nonlinear interpolation algorithm. The color compensation circuit can calculate the color compensation values ​​of all other non-target display units through the interpolation algorithm, thereby performing color compensation on all display units in the first display area.

[0083] Exemplarily, the color compensation circuit EBC can also reserve space for the compilation or secondary expansion of other parameters that may affect the color deviation effect, such as temperature, dynamic settings of the first display area, the number of positions of the target display unit marked during calculation, the size of a display unit, and other settings or linkages.

[0084] For example, taking the posture sensor as a gyroscope, the gyroscope uploads the coordinates of the display panel, including position and angle information, to the application processor AP, and the application processor AP then passes the above information to the color compensation circuit EBC inside the display driver chip DDIC. The color compensation circuit EBC calculates the first color compensation value of the target display unit based on the actual measurement results within the compensation area set by the developer, that is, the above-mentioned first display area, and calculates the second color compensation value of other non-target display units through an interpolation algorithm, and performs R, G, and B color compensation separately.

[0085] The solution of the embodiment of the present application is relatively simple to implement and can cover most usage scenarios.

[0086] In some embodiments of the present application, the electronic device also includes a posture sensor, an eye sensor and a display driver chip, and the display driver chip includes a color compensation circuit and a microprocessor; wherein the posture sensor is used to obtain posture information and send the posture information to the microprocessor, and the eye sensor is used to obtain viewing angle information and send the viewing angle information to the microprocessor.

[0087] Determining the equivalent color coordinates of each target display unit according to the posture information and the viewing angle information to obtain M equivalent color coordinates includes: controlling the microprocessor to determine the equivalent color coordinates of each target display unit according to the posture information and the viewing angle information to obtain M equivalent color coordinates.

[0088] Determining a first color compensation value for each target display unit according to each equivalent color coordinate of M equivalent color coordinates to obtain M first color compensation values ​​includes: controlling a color compensation circuit to determine the first color compensation value for each target display unit according to each equivalent color coordinate of M equivalent color coordinates to obtain M first color compensation values.

[0089] In the embodiments of this application, Figure 7 Schematic diagrams showing the structure of electronic devices in some embodiments of the present application are shown. Figure 7As shown, the electronic device includes a posture sensor, which exemplarily includes a spirit level or a gyroscope. The electronic device also includes an eye sensor, which exemplarily may be an under-screen infrared sensor, a visual sensor (such as a camera), or an eye tracker. The electronic device also includes a display driver integrated circuit (DDIC), which includes a hardware color compensation circuit (EBC) and a microcontroller unit (MCU).

[0090] When the electronic device is working, the posture sensor obtains the posture information of the current electronic device, and the eye sensor obtains the user's viewing angle information in real time. This information is sent to the microprocessor MCU in the display driver chip DDIC. The microprocessor MCU calculates the equivalent color coordinates of the target display unit based on the received posture information and viewing angle information.

[0091] The color compensation circuit EBC can be linked with a linear interpolation algorithm or a nonlinear interpolation algorithm. The color compensation circuit can calculate the color compensation values ​​of all other non-target display units through the interpolation algorithm, thereby performing color compensation on all display units in the first display area.

[0092] The data processing link in the embodiment of the present application does not need to pass through the application processor AP, the data processing link is shorter, and the processing efficiency can be improved.

[0093] The display control method of an electronic device provided in the embodiment of the present application can be executed by a display control device of the electronic device. In the embodiment of the present application, the display control device of the electronic device performing the display control method of the electronic device is taken as an example to illustrate the display control device of the electronic device provided in the embodiment of the present application.

[0094] In some embodiments of the present application, a display control device of an electronic device is provided, the electronic device includes a display panel, the display panel includes a first display area, the first display area includes N display units, the N display units are evenly distributed in the first display area, wherein the N display units include M target display units and non-target display units other than the M target display units, and N and M are both positive integers.

[0095] Figure 8 The structure block diagram of the display control device of some embodiments of the present application is shown as follows: Figure 8 As shown, the display control device 800 includes:

[0096] An acquisition module 802 is configured to acquire posture information of the electronic device and viewing angle information of the user, and determine M target display units from the N display units;

[0097] Determination module 804 is configured to determine the equivalent color coordinates of each target display unit based on the posture information and the viewing angle information to obtain M equivalent color coordinates; determine a first color compensation value for each target display unit based on each of the M equivalent color coordinates to obtain M first color compensation values; and determine a second color compensation value for each non-target display unit based on the M first color compensation values;

[0098] The control module 806 is configured to control the display panel to display content based on the first color compensation value and the second color compensation value.
