[0032] One or more technical solutions proposed in this application have at least the following technical effects: By obtaining the current viewing angle of the target interactive object relative to the reference position of the display panel, the viewing angle of the target interactive object can be determined. Since each pixel row of the display panel includes alternating first pixel groups and second pixel groups, with the first pixel group including at least one first pixel and the second pixel group including at least one second pixel, and each pixel column of the display panel includes alternating first and second pixels, an enhanced viewing angle (EVA) function can be implemented when there is a difference in brightness between the first and second pixels. Therefore, by controlling the brightness difference parameter between the first and second pixels according to the current viewing angle, the brightness difference parameter between the first and second pixels can be adaptively adjusted according to the viewing angle of the target interactive object. That is, the intensity of the EVA function can be dynamically adjusted according to the viewing angle of the target interactive object, which can reduce the negative impact of enabling the EVA function on the display effect at low viewing angles and achieve a wide viewing angle display of the display panel at high viewing angles, thereby achieving a balance between wide viewing angle and display effect.

For example, without departing from the scope of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0056] It should also be understood that, in interpreting an element, although not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of a particular value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0057] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0058] Currently, display panels using related technologies often employ fixed display modes, making it difficult to achieve a balance between wide viewing angles and display effects, resulting in a poor viewing experience for users at certain viewing angles.

[0059] Taking VA (Vertical Alignment) LCD panels as an example, due to their vertical orientation, VA LCD panels exhibit poor color shift performance at wide viewing angles and when viewed directly, especially when displaying skin tones. This distortion is severe at wide viewing angles, resulting in noticeable whitening. To address the color shift issue of VA products at wide viewing angles, LCD panel manufacturers often employ Enhanced Viewing Angle (EVA) technology. EVA technology works by artificially varying the brightness of adjacent pixels in an image, creating a brightness difference that compensates for differences in brightness at different viewing angles, thus improving the viewing angle. However, when the EVA function is activated at a certain intensity, the difference in brightness between adjacent pixels causes noticeable graininess and other undesirable subjective phenomena such as pixelation, negatively impacting the display's overall performance.

[0060] To address the aforementioned problems, the inventors further developed the technical solutions of the embodiments of this application. Specifically, the driving method for a display panel provided in the embodiments of this application includes: obtaining the current viewing angle of a target interactive object relative to a reference position of the display panel; adjusting the brightness of each first pixel and each second pixel according to the current viewing angle to adjust the brightness difference parameter between the first pixel and the second pixel, wherein each pixel row of the display panel includes alternating first pixel groups and second pixel groups, 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 alternating first pixels and second pixels, 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.

[0061] This application determines the viewing angle of the target interactive object by obtaining its current viewing angle relative to the reference position of the display panel. Since each pixel row of the display panel includes alternating first and second pixel groups (each first pixel group includes at least one first pixel, and each second pixel group includes at least one second pixel), and each pixel column of the display panel includes alternating first and second pixels, an Enhanced Viewing Angle (EVA) function can be implemented when there is a brightness difference between the first and second pixels. Therefore, by controlling the brightness difference parameter between the first and second pixels based on the current viewing angle, the brightness difference parameter between the first and second pixels can be adaptively adjusted according to the viewing angle of the target interactive object. This dynamically adjusts the intensity of the EVA function based on the viewing angle of the target interactive object, reducing the negative impact of EVA on the display effect at low viewing angles and achieving a wide viewing angle display at high viewing angles, thus achieving a balance between wide viewing angle and display effect.

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

[0063] The above is the core idea of ​​this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0064] Figure 1 This is a flowchart illustrating a method for driving a display panel according to one embodiment of this application. Figure 2 This is a schematic diagram of the structure of the display panel 11 in one embodiment of this application. Figure 1 and Figure 2 As shown, this application provides a driving method for a display panel, which can be applied to a display panel 11. The driving method for the display panel includes the following steps S101 to S102.

[0065] S101: Obtain the current viewing angle of the target interactive object relative to the reference position of the display panel, wherein each pixel row of the display panel includes an alternating first pixel group and a second pixel group, 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 an alternating first pixel and a second pixel.

[0066] Among them, such as Figure 2As shown, each pixel row of the display panel 11 includes alternating first pixel groups 111 and second pixel groups 112. The first pixel group 111 includes at least one first pixel 1111, and the second pixel group 112 includes at least one second pixel 1121. Each pixel column of the display panel 11 includes alternating first pixels 1111 and second pixels 1121. Therefore, by controlling the difference between the first pixel 1111 and the second pixel 1121, the EVA function can be enabled.

[0067] It should be noted that the interactive object can be a user detected within the interactive area of ​​the display panel 11, and the target interactive object is a user that meets preset conditions. These preset conditions can 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. Another example 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 from the detection device.

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

[0069] It is understandable that, since each pixel row of the display panel 11 includes alternating groups of first pixels 1111 and second pixels 1121, with each group of first pixels 1111 including at least one first pixel 1111 and each group of second pixels 1121 including at least one second pixel 1121, and each pixel column of the display panel 11 includes alternating groups of first pixels 1111 and second pixels 1121, by controlling the brightness of the first pixels 1111 and the second pixels 1121 to make the brightness of the first pixels 1111 and the second pixels 1121 different, the extended viewing angle EVA function can be enabled, thereby expanding the display viewing angle of the display panel 11.

[0070] S102: Adjust the brightness of each first pixel and each second pixel 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 grayscale. At the maximum or minimum grayscale value, the display brightness of each pixel on the display panel 11 is the same. Therefore, brightness adjustment is mainly for cases where the display panel 11 displays non-extreme grayscale values. The explanation of the relationship between the brightness difference parameter and the current viewing angle is also for cases where the monitor 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 a comparison under the condition that the monitor 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 non-extreme grayscale values ​​(maximum or minimum grayscale values), the brightness difference parameter corresponding to the current viewing angle is different at least at the minimum and maximum viewing angles. For example, the current viewing angle and the brightness difference parameter can be positively correlated. Also for example, the current viewing angle and the brightness difference parameter can also have a positive step function relationship, that is, there can be multiple viewing angle intervals, with different viewing angle intervals corresponding 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 is understandable that the brightness difference 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. Thus, 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. Furthermore, by adjusting the brightness of each first pixel 1111 and each second pixel 1121 according to the current viewing angle, the brightness difference parameter between the first pixel 1111 and the second pixel 1121 can be adjusted. This allows for adaptive adjustment of the brightness difference parameter between the first pixel 1111 and the second pixel 1121 based on the viewing angle of the target interactive object, i.e., dynamically adjusting the intensity of the EVA function based on the viewing angle of the target interactive object. The EVA function can be disabled at normal viewing angles, meaning the brightness of the first pixel 1111 and the second pixel 1121 can be controlled to be the same. This avoids pixelation and other defects caused by the EVA function being enabled on the display panel 11, ensuring the display effect. It can also reduce the negative impact of enabling the EVA function on the display effect at low viewing angles, i.e., reduce pixelation and other defects. At high viewing angles, it can achieve a wide viewing angle display on the display panel 11, thus ultimately achieving a balance between wide viewing angle and display effect.

[0074] The aforementioned display panel driving method determines the viewing angle of the target interactive object by obtaining its current viewing angle relative to the reference position of the display panel. Since each pixel row of the display panel includes alternating first and second pixel groups (each first pixel group includes at least one first pixel, and each second pixel group includes at least one second pixel), and each pixel column includes alternating first and second pixels, an Enhanced Viewing Angle (EVA) function can be implemented when there is a brightness difference between the first and second pixels. Therefore, by controlling the brightness difference parameter between the first and second pixels based on the current viewing angle, the brightness difference parameter can be adaptively adjusted according to the viewing angle of the target interactive object. This dynamically adjusts the intensity of the EVA function based on the viewing angle, reducing the negative impact of EVA on the display effect at low viewing angles and achieving a wide viewing angle at high viewing angles, thus achieving a balance between wide viewing angle and display effect.

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

[0076] Figure 3 This is a flowchart illustrating step S101 in one embodiment of this 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: Obtain the testing information from the testing equipment.

[0078] In the application, the detection device can perform a detection once at a preset time interval to avoid frequently adjusting the brightness of each first pixel 1111 and each second pixel 1121.

[0079] S302: Determine the viewing position of the target interactive object based on the detection information.

[0080] It is understandable that, based on 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. Based on the position information of the target interactive object, the viewing position 12 of the target interactive object can be determined. For example, the middle position between the user's two eyeballs can be determined as the viewing position 12. Another example is that the user's center position can be determined as the viewing position 12.

[0081] S303: Obtain the current viewpoint based on the viewing position and the reference position.

[0082] It is understandable that after determining the viewing position 12 and the reference position 113 of the target interactive object, 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. The viewing position 12 of the target interactive object can be obtained in real time or at intervals, so the current viewing angle can be determined in real time or at intervals. Thus, 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 parameter between the first pixel 1111 and the second pixel 1121. That is, the intensity of the EVA function is dynamically adjusted according to the viewing angle of the target interactive object, so as to achieve a balance between wide viewing angle and display effect.

[0084] Figure 4 This is a flowchart illustrating step S303 in one embodiment of this application. In one embodiment, as... Figure 4 As shown, in step S303, the step of obtaining the current viewpoint based on the viewing position and the reference position includes the following steps S401 to S402.

[0085] S401: The line connecting the viewing position and the reference position is determined as the evaluation line.

[0086] It is understood that the reference position 113 is preset and the position information of the reference position 113 is known, while the viewing position 12 can be determined according to the detection information of the detection equipment. Based on this, a line connecting the viewing position 12 and the reference position 113 can be constructed as the evaluation line S1 to help determine the current viewing angle.

[0087] S402: Obtain the current viewing angle based on the angle between the evaluation line and the baseline, wherein the baseline passes through the reference position and is perpendicular to the plane where the display panel is located.

[0088] Figure 5 This is a schematic diagram illustrating the principle of obtaining the current viewpoint in one embodiment of this application. It can be understood that, as... 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. Therefore, 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 application, the angle θ between the evaluation line S1 and the reference line S2 can also be optimized using relevant methods, and the optimized angle can be determined as the current viewing angle.

[0089] In this embodiment, the line connecting the viewing position 12 and the reference position 113 is defined as the evaluation line S1, and the current viewing angle is obtained based on the angle between the evaluation line S1 and the reference line S2. This determines the current viewing angle of the target interactive object relative to the reference position 113, thereby enabling the control of the brightness difference parameter between the first pixel 1111 and the second pixel 1121 based on the current viewing angle. In other words, 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, achieving a balance between wide viewing angle and display effect, and improving the user's viewing experience.

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

[0091] The upper limit of the viewing angle range can be set according to requirements, but it must be less than the maximum viewing angle. For example, the upper limit can be set to 0 degrees, meaning that when the current viewing angle is 0 degrees (the target interactive object is completely in a direct viewing angle relative to the display panel 11), the brightness of the first pixel 1111 and the second pixel 1121 will remain the same. Alternatively, the upper limit of the viewing angle range can be set to 10 degrees, making the viewing angle range [0°, 10°]. When the current viewing angle is within this range, the brightness of the first pixel 1111 and the second pixel 1121 will remain the same. Furthermore, the upper limit 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 limits are merely examples and do not constitute a limitation on the upper limit of the viewing angle range.

[0092] It is understandable that when the target interactive object views the display panel 11 from a normal or near-normal angle, the display panel 11 does not need to be displayed with a wide viewing angle. In this case, the display effect of the display panel 11 should be guaranteed as much as possible. Therefore, the display panel 11 does not need to enable the EVA function in this case.

[0093] In this embodiment, when the current viewing angle is within the normal viewing angle range, controlling the brightness of the first pixel 1111 and the second pixel 1121 to remain the same can avoid the pixelation and other undesirable phenomena caused by the EVA function being enabled on the display panel 11, thereby ensuring the display effect of the display panel 11 and improving the user's viewing experience.

[0094] Figure 6 This is a flowchart illustrating step S102 in one embodiment of this application. In another embodiment, as... Figure 6As shown, step 102, which involves 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 the target view range of the current view, wherein the target view range is one of a plurality of preset view ranges.

[0096] Figure 7 This is a schematic diagram of a viewpoint comparison table in one embodiment of this application. Figure 7 As shown, in the application, a viewpoint lookup table can be pre-defined. This table includes multiple viewpoint ranges, each corresponding to different parameters and EVA intensity. After obtaining the current viewpoint, the viewpoint lookup table is called to determine the viewpoint range within which the current viewpoint is located, and this range is then designated as the target viewpoint range. It should be noted that... Figure 7 The EVA intensity and parameters shown are not specific values, but only represent the correspondence with the viewpoint, and different viewpoint ranges correspond to different EVA intensity and parameters.

[0097] S602: Determine the first target parameter and the second target parameter based on the grayscale contrast relationship between the current grayscale value and the target viewing angle range.

[0098] Figure 8 This is a grayscale contrast diagram corresponding to the current viewpoint in one embodiment of this application. In one example, such as... 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. Then, based on the current grayscale value, the first target parameter and the second target parameter can be determined by looking up the grayscale comparison curves, that is, the code values ​​corresponding to the first pixel 1111 and the second pixel 1121. The code values ​​control the brightness of the pixels. Therefore, the 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 can also be the 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 is 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 applications, the first target parameter and the second target parameter can also be other brightness-related parameters.

[0102] S603: Adjust the brightness of each first pixel according to the first target parameter, and adjust 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 parameter of the first pixel 1111 and the second pixel 1121.

[0104] In this embodiment, by obtaining 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, respectively, 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. This achieves adaptive adjustment of the brightness difference parameter between the first pixel 1111 and the second pixel 1121 based on the viewing angle of the target interactive object. Moreover, by setting multiple viewing angle ranges, the brightness of the first pixel 1111 and the second pixel 1121 can be avoided when the current viewing angle changes slightly, thereby preventing frequent changes in the brightness of the first pixel 1111 and the second pixel 1121 and improving the service life of the display panel 11.

[0105] Figure 9 This is a schematic diagram illustrating the process of determining a target interaction object in one embodiment of this application. In one embodiment, such as Figure 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: Obtain the detection information from the testing equipment.

[0107] S902: Determine the candidate interactive objects within the interactive area based on the detection information from the detection equipment.

[0108] The interactive area is the area that can interact with the display panel 11, such as the viewable area covered by the display panel 11.

[0109] It is understandable that the detection information from the testing equipment can determine whether there is an interactive object within the interactive area covered by the display panel 11. The interactive object can be a human body or a testing device that conforms to the set rules. If it is determined that there is an interactive object within the interactive area, the interactive object within the interactive area is identified as a candidate interactive object.

[0110] S903: If there is only one candidate interaction object, the candidate interaction object will be determined as the target interaction object.

[0111] It is understandable that if there is only one candidate interaction object, then only the viewing experience of that candidate interaction object needs to be considered. Therefore, the candidate interaction object is directly determined as the target interaction object.

[0112] S904: When there are multiple candidate interactive objects, obtain the viewpoint of each candidate interactive object relative to the reference position, and determine the candidate interactive object corresponding to the largest viewpoint as the target interactive object.

[0113] It is understandable that when there are multiple candidate interactive objects, determining the candidate interactive object corresponding to the largest viewing angle as the target interactive object can ensure that each candidate interactive object can view the content displayed on the display panel 11.

[0114] In this embodiment, candidate interactive objects within the interactive area can be determined based on the detection information from the detection device. If only one candidate interactive object exists, only the viewing experience of that object needs to be considered, and the candidate interactive object is designated as the target interactive object, maximizing the viewing experience of the target interactive object. However, if multiple candidate interactive objects exist, the candidate interactive object corresponding to the largest viewing angle is designated as the target interactive object, taking into account the viewing experience of each candidate interactive object and ensuring that each candidate interactive object can view the content displayed on the display panel 11.

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

[0116] It is understood that when the detection device is an optical detection device, the detection information includes the image information of the interactive object. By recognizing 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 application, there may be situations where interactive objects that are not viewing the display panel 11 remain in the interaction area, while interactive objects whose faces are facing the display panel 11 can be determined to be viewing the display panel 11. Therefore, identifying interactive objects with their faces facing the display panel 11 within the interaction area as candidate interactive objects can avoid interference from interactive objects that are not viewing the panel and improve the viewing experience of interactive objects that are viewing the display panel 11.

[0117] In this embodiment, based on the detection information, the interactive objects with faces facing the display panel 11 within the interactive area are determined, and these interactive objects are identified as candidate interactive objects. This avoids interference from interactive objects that do not view the panel and improves the viewing experience of interactive objects that view the display panel 11.

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