[0052] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0055] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present application.

[0056] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0057] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0058] At present, display panels of related technologies often adopt a fixed display mode, which makes it difficult to achieve a balance between wide viewing angle and display effect, resulting in a poor viewing experience for users at certain viewing angles.

[0059] Taking VA (Vertical Alignment) type LCD panel as an example, VA LCD panel has poor color deviation performance under wide viewing angle and normal viewing angle due to its vertical standing characteristics, especially when displaying skin color images, the wide viewing angle display distortion is serious and there is obvious whitening phenomenon. When LCD panel manufacturers are dealing with the problem of color deviation of VA products with large viewing angle, they often use Enhance Viewing Angle (EVA) technology. The principle of EVA technology is to artificially make the adjacent pixels in the image display different brightness, resulting in a brightness difference, so that the brightness is compensated when observed at different angles, so as to achieve the effect of improving the viewing angle of the display panel. However, after the EVA function of the display panel is turned on at a certain intensity, the difference in brightness between adjacent pixels will cause obvious graininess visually, as well as adverse subjective phenomena such as shaking head lines, which can easily have a negative impact on the display effect of the display panel.

[0060] In order to solve the above problems, the inventors further studied the technical solutions of the embodiments of the present application. Specifically, the driving method of the display panel provided in the embodiments of the present application includes: obtaining the current viewing angle of the target interactive object relative to the reference position of the display panel; adjusting the brightness of each of the first pixels and each of the second pixels according to the current viewing angle to adjust the brightness difference parameter of the first pixel and the second pixel, wherein each pixel row of the display panel includes a first pixel group and a second pixel group arranged alternately, the first pixel group includes at least one first pixel, the second pixel group includes at least one second pixel, and each pixel column of the display panel includes the first pixels and the second pixels arranged alternately, and when the first viewing angle is greater than the second viewing angle, the first brightness difference parameter corresponding to the first viewing angle is greater than or equal to the second brightness difference parameter corresponding to the second viewing angle.

[0061] The present application can determine the viewing angle of the target interactive object by acquiring the current viewing angle of the target interactive object relative to the reference position of the display panel. Since each pixel row of the display panel includes a first pixel group and a second pixel group arranged alternately, the first pixel group includes at least one first pixel, the second pixel group includes at least one second pixel, and each pixel column of the display panel includes a first pixel and a second pixel arranged alternately, when there is a difference in the brightness of the first pixel and the second pixel, the Enhance Viewing Angle (EVA) function can be implemented. Therefore, by controlling the brightness difference parameter of the first pixel and the second pixel according to the current viewing angle, the brightness difference parameter of the first pixel and the second pixel can be adaptively adjusted according to the viewing angle of the target interactive object, that is, the intensity of the EVA function is dynamically adjusted according to the viewing angle of the target interactive object, and the negative impact of turning on the EVA function on the display effect can be reduced at a low viewing angle, and the wide viewing angle display of the display panel can be achieved at a high viewing angle, thereby achieving a balance between the wide viewing angle and the display effect.

[0062] It should be noted that the execution subject of this embodiment may be a display driver chip of a display panel, or other processing devices that can control the display brightness of the display panel. The following takes the display driver chip as an example to illustrate this embodiment and the following embodiments.

[0063] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be described clearly and completely below in conjunction with the drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] Figure 1 is a flow chart of a method for driving a display panel in one embodiment of the present application, Figure 2 FIG. 1 is a schematic diagram of the structure of a display panel 11 in an embodiment of the present application. Figure 1 and Figure 2 As shown, the present application provides a method for driving a display panel, which can be applied to a display panel 11 , and includes the following steps S101 to S102 .

[0065] S101: Acquire a current viewing angle of a target interactive object relative to a reference position of a display panel, wherein each pixel row of the display panel includes a first pixel group and a second pixel group arranged alternately, the first pixel group includes at least one first pixel, the second pixel group includes at least one second pixel, and each pixel column of the display panel includes a first pixel and a second pixel arranged alternately.

[0066] Among them, Figure 2As shown, each pixel row of the display panel 11 includes a first pixel group 111 and a second pixel group 112 arranged alternately, the first pixel group 111 includes at least one first pixel 1111, the second pixel group 112 includes at least one second pixel 1121, and each pixel column of the display panel 11 includes a first pixel 1111 and a second pixel 1121 arranged alternately. By controlling the difference between the first pixel 1111 and the second pixel 1121, the EVA function can be turned on.

[0067] It should be noted that the interactive object may be a user detected in the interactive area of ​​the display panel 11, and the target interactive object may be a user that meets the preset conditions, and the preset conditions may be set according to actual needs. For example, the preset condition is the interactive object with the largest current viewing angle relative to the display panel 11. For another example, the preset condition is the interactive object closest to the display panel 11. In this embodiment, the preset conditions are not specifically limited. The current viewing angle of the target interactive object relative to the reference position 113 of the display panel 11 can be obtained based on the detection information of the detection device.

[0068] It should also be noted that the reference position 113 of the display panel 11 can be preset, for example, Figure 2 As shown, the reference position 113 may be the center position of the display panel 11 . For another example, the reference position 113 may be the center position of the display area of ​​the display panel 11 .

[0069] It can be understood that since each pixel row of the display panel 11 includes alternately arranged first pixel 1111 group 111 and second pixel 1121 group 112, the first pixel 1111 group 111 includes at least one first pixel 1111, and the second pixel 1121 group 112 includes at least one second pixel 1121, and each pixel column of the display panel 11 includes alternately arranged first pixels 1111 and second pixels 1121, by controlling the brightness of the first pixel 1111 and the second pixel 1121 so that there is a difference in the brightness of the first pixel 1111 and the second pixel 1121, the extended viewing angle EVA function can be turned on, thereby expanding the display viewing angle of the display panel 11.

[0070] S102: Adjust the brightness of each first pixel and each second pixel respectively according to the current viewing angle to adjust the brightness difference parameter between the first pixel and the second pixel, wherein when the first viewing angle is greater than the second viewing angle, the first brightness difference parameter corresponding to the first viewing angle is greater than or equal to the second brightness difference parameter corresponding to the second viewing angle.

[0071] It should be noted that the display brightness of the display panel 11 is related to the grayscale. At the maximum or minimum grayscale value, the display brightness of each pixel of the display panel 11 is the same. Therefore, the brightness adjustment is mainly aimed at the case where the display panel 11 displays non-extreme grayscale values. The description of the relationship between the brightness difference parameter and the current viewing angle is also for the case where the display displays the same grayscale. For example, the first brightness difference parameter corresponding to the first viewing angle and the first brightness difference parameter corresponding to the second viewing angle are compared when the display displays the same grayscale.

[0072] In the application, the viewing angle of the target interactive object relative to the reference position 113 of the display panel 11 is within a certain range, for example, it can be 0 to 90 degrees. When the display panel 11 displays a non-extreme grayscale value (maximum or minimum grayscale value), the brightness difference parameter corresponding to the current viewing angle is different at least between the minimum viewing angle and the maximum viewing angle. Exemplarily, the current viewing angle and the brightness difference parameter can be positively correlated. Also exemplarily, the current viewing angle and the brightness difference parameter can also be in a positive step function relationship, that is, there can be multiple viewing angle intervals, different viewing angle intervals correspond to different brightness difference parameters, and the current brightness difference parameter is determined according to the viewing angle interval in which the current viewing angle is located.

[0073] It can be understood that the brightness difference value between the first pixel 1111 and the second pixel 1121 directly affects the intensity of the EVA function. Therefore, based on the principle of EVA technology, the brightness difference parameter between the first pixel 1111 and the second pixel 1121 is positively correlated with the intensity of the EVA function. By adjusting the brightness difference parameter between the first pixel 1111 and the second pixel 1121, the intensity of the EVA function can be adjusted. On this basis, the brightness of each first pixel 1111 and each second pixel 1121 is adjusted according to the current viewing angle to adjust the brightness difference parameter between the first pixel 1111 and the second pixel 1121. It can be achieved that the brightness difference parameter between the first pixel 1111 and the second pixel 1121 is adaptively adjusted according to the viewing angle of the target interactive object, that is, the intensity of the EVA function is dynamically adjusted according to the viewing angle of the target interactive object. The EVA function may be disabled at a normal viewing angle, that is, the brightness of the first pixel 1111 and the second pixel 1121 may be controlled to be the same, so as to avoid undesirable phenomena such as pixel graininess on the display panel 11 caused by turning on the EVA function, thereby ensuring the display effect. The negative impact of turning on the EVA function on the display effect may also be reduced at a low viewing angle, that is, undesirable phenomena such as pixel graininess are reduced, and a wide viewing angle display of the display panel 11 may be achieved at a high viewing angle, thereby ultimately achieving a balance between a wide viewing angle and a display effect.

[0074] The above-mentioned display panel driving method can determine the viewing angle of the target interactive object by acquiring the current viewing angle of the target interactive object relative to the reference position of the display panel, and since each pixel row of the display panel includes a first pixel group and a second pixel group arranged alternately, the first pixel group includes at least one first pixel, the second pixel group includes at least one second pixel, and each pixel column of the display panel includes a first pixel and a second pixel arranged alternately, when there is a difference in brightness between the first pixel and the second pixel, the Enhance Viewing Angle (EVA) function can be realized. Therefore, by controlling the brightness difference parameter of the first pixel and the second pixel according to the current viewing angle, the brightness difference parameter of the first pixel and the second pixel can be adaptively adjusted according to the viewing angle of the target interactive object, that is, the intensity of the EVA function is dynamically adjusted according to the viewing angle of the target interactive object, and the negative impact of turning on the EVA function on the display effect can be reduced at a low viewing angle, and the wide viewing angle display of the display panel can be realized at a high viewing angle, thereby achieving a balance between the wide viewing angle and the display effect.

[0075] In one embodiment, the display panel 11 includes a detection device, which may be a wide-angle camera or an infrared sensor, etc. The detection device may be arranged at a corresponding position of the display panel 11 as required. For example, the detection device may be arranged at a reference position 113 of the display panel 11.

[0076] Figure 3 FIG. 1 is a flow chart of step S101 in an embodiment of the present application. Figure 3 As shown, in step S101, the step of obtaining the current viewing angle of the target interactive object relative to the reference position of the display panel includes the following steps S301 to S303.

[0077] S301: Acquire detection information of a detection device.

[0078] In applications, the detection device may perform detection once at a preset interval to avoid frequent adjustment of the brightness of each first pixel 1111 and each second pixel 1121 .

[0079] S302: Determine a viewing position of the target interactive object according to the detection information.

[0080] It can be understood that based on the preset rules, the target interactive object can be determined according to the detection information of the detection device, and the position information of the target interactive object can be determined, and the viewing position 12 of the target interactive object can be determined based on the position information of the target interactive object. Exemplarily, the middle position of the two eyeballs of the user can be determined as the viewing position 12. Also exemplarily, the center position of the user can be determined as the viewing position 12.

[0081] S303: Acquire the current viewing angle according to the viewing position and the reference position.

[0082] It can be understood that after the viewing position 12 and the reference position 113 of the target interactive object are determined, the viewing angle of the target interactive object can be determined based on the viewing position 12, the reference position 113 and the plane where the display panel 11 is located, thereby obtaining the current time.

[0083] In this embodiment, the viewing position 12 of the target interactive object is determined by the detection information of the detection device, and the viewing position 12 of the target interactive object can be obtained in real time or at intervals, so that the current viewing angle can be determined in real time or at intervals, so that the brightness of each first pixel 1111 and each second pixel 1121 can be dynamically adjusted according to the current viewing angle, so as to dynamically adjust the brightness difference parameters between the first pixel 1111 and the second pixel 1121, that is, dynamically adjust the intensity of the EVA function according to the viewing angle of the target interactive object to achieve a balance between wide viewing angle and display effect.

[0084] Figure 4 FIG. 1 is a flow chart of step S303 in an embodiment of the present application. Figure 4 As shown, in step S303, the step of acquiring the current viewing angle according to the viewing position and the reference position includes the following steps S401 to S402.

[0085] S401: Determine a line connecting the viewing position and the reference position as an evaluation line.

[0086] It can be understood that the reference position 113 is pre-set, and the position information of the reference position 113 is known, and the viewing position 12 can be determined based on the detection information of the detection device. On this basis, the line connecting the viewing position 12 and the reference position 113 can be constructed as the evaluation line S1 to assist in determining the current viewing angle.

[0087] S402: Obtaining a current viewing angle according to an angle between the evaluation line and a reference line, wherein the reference line passes through a reference position and is perpendicular to a plane where the display panel is located.

[0088] Figure 5 FIG. 1 is a schematic diagram of the principle of obtaining the current viewing angle in an embodiment of the present application. It can be understood that, if Figure 5 As shown, since the plane where the display panel 11 is located and the reference position 113 are determined, the reference line S2 can also be determined, so the angle θ between the evaluation line S1 and the reference line S2 can be determined, and then the angle θ between the evaluation line S1 and the reference line S2 can be determined as the current viewing angle, thereby obtaining the current viewing angle. In the application, the angle θ between the evaluation line S1 and the reference line S2 can also be optimized by a related method, and the optimized angle is determined as the current viewing angle.

[0089] In this embodiment, the line connecting the viewing position 12 and the reference position 113 is determined as the evaluation line S1, and the current viewing angle is obtained according to the angle between the evaluation line S1 and the reference line S2, thereby determining the current viewing angle of the target interactive object relative to the reference position 113. Then, the brightness difference parameters of the first pixel 1111 and the second pixel 1121 can be controlled according to the current viewing angle, that is, the brightness difference parameters of the first pixel 1111 and the second pixel 1121 are adaptively adjusted according to the viewing angle of the target interactive object, thereby achieving a balance between wide viewing angle and display effect, and improving the user's viewing experience.

[0090] In one embodiment, in step S102, the step of adjusting the brightness of each first pixel and each second pixel according to the current viewing angle to adjust the brightness difference parameter of the first pixel and the second pixel includes: when the current viewing angle is in the positive viewing angle interval, the step of controlling the brightness of the first pixel and the second pixel to remain the same. The lower limit value of the positive viewing angle interval is 0 degrees.

[0091] Among them, the upper limit value of the positive viewing angle interval can be set according to the needs, but the upper limit value is less than the maximum viewing angle value. For example, the upper limit value can also be set to 0 degrees, that is, when the current viewing angle is 0 degrees (the target interactive object is completely in the positive viewing angle relative to the display panel 11), the brightness of the first pixel 1111 and the second pixel 1121 are controlled to remain the same. For another example, the upper limit value of the positive viewing angle interval can also be set to 10 degrees at present, then the positive viewing angle interval is [0°, 10°]. When the current viewing angle is in this interval, the brightness of the first pixel 1111 and the second pixel 1121 are controlled to remain the same. Furthermore, the upper limit value can also be other values, such as 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, and 9 degrees. It should be noted that the above upper limit values ​​are merely examples and do not constitute a limitation on the upper limit value of the positive viewing angle interval.

[0092] It can be understood that when the target interactive object views the display panel 11 at a normal viewing angle or a near normal viewing angle, the display panel 11 does not need to display at a wide viewing angle. At this time, the display effect of the display panel 11 should be guaranteed as much as possible. Therefore, the display panel 11 does not need to turn on the EVA function in this case.

[0093] In this embodiment, when the current viewing angle is in the positive viewing angle range, the brightness of the first pixel 1111 and the second pixel 1121 are controlled to remain the same, which can avoid undesirable phenomena such as pixel graininess caused by turning on the EVA function of the display panel 11, thereby ensuring the display effect of the display panel 11 and improving the user's viewing experience.

[0094] Figure 6 FIG. 1 is a flow chart of step S102 in one embodiment of the present application. In another embodiment, Figure 6As shown, in step 102, the step of adjusting the brightness of each first pixel and each second pixel according to the current viewing angle includes the following steps S601 to S603.

[0095] S601: Obtain a target viewing angle range of a current viewing angle, wherein the target viewing angle range is one of a plurality of preset viewing angle ranges.

[0096] Figure 7 FIG. 1 is a schematic diagram of a viewing angle comparison table in an embodiment of the present application. Figure 7 As shown, in the application, a viewing angle comparison table can be pre-set, and the viewing angle comparison table includes multiple viewing angle ranges, each viewing angle range corresponds to different parameters and EVA strengths. After obtaining the current viewing angle, the viewing angle comparison table is called to check the table to determine the viewing angle range of the current viewing angle, and the viewing angle range of the current viewing angle is determined as the target viewing angle range. It should be noted that Figure 7 The EVA strength and parameters shown in are not specific values, but only indicate the corresponding relationship with the viewing angle, and different viewing angle ranges correspond to different EVA strengths and parameters.

[0097] S602: Determine a first target parameter and a second target parameter according to a grayscale comparison relationship corresponding to a current grayscale value and a target viewing angle range.

[0098] Figure 8 is a grayscale comparison diagram corresponding to the current viewing angle in an embodiment of the present application. Figure 8 As shown, different viewing angles correspond to different grayscale comparison curves, and the same viewing angle corresponds to two grayscale comparison curves, the upper curve corresponds to high-brightness pixels, and the lower curve corresponds to low-brightness pixels. After determining the current viewing angle, two grayscale comparison curves corresponding to the current viewing angle can be determined, and then the grayscale comparison curves are checked according to the current grayscale value to determine the first target parameter and the second target parameter, that is, the code value corresponding to the first pixel 1111 and the second pixel 1121. The code value controls the luminous brightness of the pixel, so the luminous brightness of the first pixel 1111 and the second pixel 1121 can be controlled.

[0099] In another example, the first target parameter and the second target parameter may also be display brightness, respectively. In this case, the first target parameter corresponds to the target brightness of the first pixel 1111 , and the second target parameter corresponds to the target brightness of the second pixel 1121 .

[0100] It can be understood that the driving voltages corresponding to the first pixel 1111 and the second pixel 1121 are different. The first driving voltage corresponding to the first pixel 1111 is used to control the display brightness of the first pixel 1111, and the second driving voltage corresponding to the second pixel 1121 is used to control the display brightness of the second pixel 1121. Therefore, the first target parameter and the second target parameter can also be driving voltages respectively. The first target parameter corresponds to the target driving voltage of the first pixel 1111, and the second target parameter corresponds to the target driving voltage of the second pixel 1121.

[0101] It should be noted that, in the application, the first target parameter and the second target parameter may also be other parameters related to brightness.

[0102] S603: adjusting the brightness of each first pixel according to the first target parameter, and adjusting the brightness of each second pixel according to the second target parameter.

[0103] It should be noted that when the first target parameter and the second target parameter are code value parameters, the first target parameter and the second target parameter are called to adjust the brightness of each first pixel 1111 and the brightness of each second pixel 1121 to the second target parameter, thereby controlling the brightness difference parameters of the first pixel 1111 and the second pixel 1121.

[0104] In this embodiment, by acquiring the target viewing angle range of the current viewing angle, and determining the first display parameter and the second display parameter corresponding to the target viewing angle range as the first target parameter and the second target parameter, the brightness of each first pixel 1111 can be adjusted according to the first target parameter, and the brightness of each second pixel 1121 can be adjusted according to the second target parameter, so as to realize adaptive adjustment of the brightness difference parameter of the first pixel 1111 and the second pixel 1121 according to the viewing angle of the target interactive object. Moreover, by setting multiple viewing angle ranges, it is possible to avoid adjusting the brightness of the first pixel 1111 and the second pixel 1121 when the current viewing angle changes slightly, thereby avoiding frequent changes in the brightness of the first pixel 1111 and the second pixel 1121, which is conducive to improving the service life of the display panel 11.

[0105] Fig. 9 FIG. 1 is a flow chart of determining a target interaction object in an embodiment of the present application. Fig. 9 As shown, before the step of obtaining the current viewing angle of the target interactive object relative to the reference position of the display panel, the following steps S901 to S904 are also included.

[0106] S901: Acquire detection information of the detection device.

[0107] S902: Determine candidate interaction objects in the interaction area according to detection information of the detection device.

[0108] The interactive area is an area that can interact with the display panel 11 , for example, it can be a viewable area covered by the display panel 11 .

[0109] It can be understood that, based on the detection information of the detection device, it can be determined whether there is an interactive object in the interactive area covered by the display panel 11. The interactive object can be a human body or a test device that meets the set rules. When it is determined that there is an interactive object in the interactive area, the interactive object in the interactive area is determined as a candidate interactive object.

[0110] S903: When there is only one candidate interaction object, determine the candidate interaction object as the target interaction object.

[0111] It can be understood that when there is only one candidate interactive object, only the viewing experience of the candidate interactive object needs to be considered, and therefore, the candidate interactive object is directly determined as the target interactive object.

[0112] S904: When there are multiple candidate interaction objects, obtain the viewing angle of each candidate interaction object relative to the reference position, and determine the candidate interaction object corresponding to the maximum viewing angle as the target interaction object.

[0113] It can be understood that when there are multiple candidate interaction objects, determining the candidate interaction object corresponding to the maximum viewing angle as the target interaction object can ensure that each candidate interaction object can view the display content of the display panel 11.

[0114] In this embodiment, the candidate interactive objects in the interactive area can be determined based on the detection information of the detection device. When there is only one candidate interactive object, only the viewing experience of the candidate interactive object needs to be considered, and the candidate interactive object is determined as the target interactive object, which can maximize the viewing experience of the target interactive object. When there are multiple candidate interactive objects, the candidate interactive object corresponding to the maximum viewing angle is determined as the target interactive object, which can take into account the viewing experience of each candidate interactive object and ensure that each candidate interactive object can view the display content of the display panel 11.

[0115] In one embodiment, the detection device is an optical detection device, such as a camera. In step S902, the step of determining candidate interactive objects in the interactive area according to the detection information of the detection device includes: determining the interactive objects in the interactive area whose faces are facing the display panel according to the detection information; and determining the interactive objects in the interactive area whose faces are facing the display panel as candidate interactive objects.

[0116] It can be understood that when the detection device is an optical detection device, the detection information includes the image information of the interactive object. By identifying the image information of the interactive object, the panel orientation of the interactive object can be determined, thereby confirming whether the interactive object is viewing the display panel 11. In applications, there may be a situation where an interactive object that is not viewing the display panel 11 stays in the interactive area, and the interactive object whose face is facing the display panel 11 can be determined to be viewing the display panel 11. Therefore, determining the interactive object whose face is facing the display panel 11 in the interactive area as a candidate interactive object can avoid interference from the interactive object that is not viewing the panel and improve the viewing experience of the interactive object viewing the display panel 11.

[0117] In this embodiment, the interactive object whose face is facing the display panel 11 in the interactive area is determined based on the detection information, and the interactive object whose face is facing the display panel 11 in the interactive area is determined as a candidate interactive object, thereby avoiding interference from the interactive object that is not viewing the panel and improving the viewing experience of the interactive object viewing the display panel 11.

[0118] In the application, in other embodiments, the time when the face of the interactive object is facing the display panel 11 can also be determined based on the detection information, and the interactive object whose face is facing the display panel 11 for more than a preset threshold can be determined as a candidate interactive object, thereby further improving the accuracy and ensuring that the candidate interactive object is the interactive object viewing the display panel 11.
