[0073] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of this specification shall have the common meanings understood by persons with ordinary skills in the field to which this specification belongs. The words "first", "second" and similar words used in the embodiments of this specification do not indicate any order, quantity or importance, but are only used to avoid confusion of constituent elements.

[0074] Unless the context requires otherwise, throughout the specification, "plurality" means "at least two", and "including" is interpreted as an open, inclusive meaning, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples", "specific examples" or "some examples" are intended to indicate that a particular feature, structure, material or characteristic associated with the embodiment or example is included in at least one embodiment or example of the specification. The schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0075] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0076] Conventional display panels (e.g., liquid crystal display panels, light-emitting diode display panels, organic light-emitting diode display panels, active-matrix organic light-emitting diode display panels, etc.) all display at a fixed refresh rate, such as 60 Hz or 120 Hz. In other words, regardless of the application scenario, the refresh rate of the display panel remains unchanged in the working state.

[0077] In recent years, with the rapid development of display technology, low-power display panels have become an important development trend. As an important technical means to reduce the power consumption of display panels, switching between high and low frequencies has also attracted more attention. However, when the display frequency of the display panel is less than the preset refresh frequency, the display of the picture will appear in the form of a hold frame. For example, when the preset frequency of the display panel is 120Hz and the display frequency of the display panel is 30Hz, a picture will be displayed in the form of a write frame and a hold frame. It should be noted that the preset frequency is generally the highest frequency of the display panel, wherein the write frame is displayed after writing data, and the write frame is followed by three hold frames, and the data written by the write frame is maintained for display. There will be a black insertion stage between the write frame and the hold frame to ensure the display effect. Generally, there is only one write frame and there can be multiple hold frames. The inventor found that the frequency reduction display method will cause the display panel to flicker, resulting in a decrease in user experience.

[0078] To this end, the present application provides a solution that can effectively improve the screen flicker problem. By adjusting the display voltage of the first frame holding the current picture so that the display voltage of the first frame holding the current picture is different from the display voltage of the write frame, the voltage of the first frame holding the first frame after the write frame can be adjusted, that is, the brightness of the first frame holding the first frame after the write frame can be adjusted, so that the display effect of the first frame holding the first frame is basically the same as the display effect of the write frame, thereby avoiding the screen flicker problem on the display panel and improving the display effect.

[0079] Specifically, as an optional implementation of the content disclosed in this application, the embodiment of this application provides a display method, such as Figure 1 As shown, the display method may specifically include the following implementation steps:

[0080] S101 . In response to a display frequency of a current picture being less than a preset frequency, determining a display voltage corresponding to a first frame of the current picture, wherein the display voltage of the first frame of the current picture is at least partially different from a display voltage of a write frame of the current picture.

[0081] For example, the preset frequency is 120 Hz, the display frequency of the current picture is 60 Hz, and 60 Hz is less than 120 Hz, then it is determined that the display frequency of the current picture is less than the preset frequency. The preset frequency is generally the highest frequency of the display device.

[0082] Specifically, the display frequency of the current picture is less than the preset frequency, which may be due to receiving a refresh rate switching instruction carrying the display frequency of the current picture. Accordingly, the preset frequency is the display frequency before the refresh rate switching, and the display frequency of the current picture is the display frequency after the refresh rate switching. The display frequency of the current picture is less than the preset frequency, which is a manifestation of the picture frequency reduction.

[0083] The display voltage of the first frame holding frame of the current picture is at least partially different from the display voltage of the written frame of the current picture, that is, the display voltage corresponding to the first frame holding frame of the current picture is a voltage after compensating and adjusting the reference voltage corresponding to the first frame holding frame of the current picture, thereby realizing the adjustment of the brightness of the first frame holding frame after the written frame, so that the display effect of the first frame holding frame can be basically the same as the display effect of the written frame, thereby avoiding the occurrence of screen flickering.

[0084] S102 , displaying the first frame holding frame of the current picture according to the display voltage of the first frame holding frame of the current picture.

[0085] By using the display voltage of the compensated first frame holding frame to display the first frame holding frame of the current picture, it is possible to avoid a large voltage difference between the display voltage of the first frame holding frame and the display voltage of the write frame, thereby avoiding screen flickering caused by frequency reduction.

[0086] In this embodiment, in response to the display frequency of the current picture being less than the preset frequency, the display voltage corresponding to the first frame holding frame of the current picture is determined, and the display voltage of the first frame holding frame of the current picture is at least partially different from the display voltage of the written frame of the current picture; and then the first frame holding frame of the current picture is displayed according to the display voltage of the first frame holding frame of the current picture. In this way, by adjusting the display voltage of the first frame holding frame of the current picture so that the display voltage of the first frame holding frame of the current picture is different from the display voltage written by the written frame, the voltage adjustment of the first frame holding frame after the written frame can be achieved, that is, the brightness of the first frame holding frame after the written frame can be adjusted, so that the display effect of the first frame holding frame is basically the same as the display effect of the written frame, avoiding the problem of screen flickering on the display panel and improving the display effect.

[0087] In some embodiments, in order to further reduce the screen flickering phenomenon, the above-mentioned response to the display frequency of the current picture being less than the preset frequency, determining the display voltage corresponding to the first frame of the current picture to maintain the frame, can specifically include: in response to the display frequency of the current picture being less than the preset frequency, and the display frequency of the current picture is different from the display frequency of the previous picture of the current picture, determining the display voltage corresponding to the first frame of the current picture to maintain the frame.

[0088] The display frequency of the current picture may be less than the display frequency of the picture before the current picture.

[0089] When implementing, Figure 2 As shown, in response to the display frequency of the current picture being less than the preset frequency, and the display frequency of the current picture being different from the display frequency of the picture before the current picture, determining the display voltage corresponding to the first frame of the current picture to hold the frame may specifically include the following steps:

[0090] S201 , determining a first corresponding relationship according to a display frequency of a previous picture of a current picture and a display frequency of a current picture, wherein the first corresponding relationship is a corresponding relationship between an initial voltage of a first frame holding frame of the current picture and a display voltage.

[0091] Specifically, the correspondence between the display frequency of the previous screen and the display frequency of the current screen and the first correspondence can be pre-constructed, so that the display frequencies of different previous screens and the display frequencies of the current screen have their unique corresponding first correspondences, thereby laying the foundation for obtaining a more accurate first correspondence.

[0092] After constructing the correspondence between the display frequency of the previous picture and the display frequency of the current picture and the first correspondence, the corresponding first correspondence can be determined based on the acquired display frequency of the previous picture of the current picture and the display frequency of the current picture, thereby laying the foundation for further obtaining a more accurate display voltage of the first frame holding frame of the current picture.

[0093] It should be noted that the initial voltage of the first frame holding frame is the voltage before the first frame holding frame is compensated and adjusted, and the display voltage is the voltage after the initial voltage of the first frame holding frame is compensated and adjusted.

[0094] S202 , determining a display voltage of the first frame holding frame of the current picture according to an initial voltage of the first frame holding frame of the current picture and a first corresponding relationship.

[0095] After the first corresponding relationship is determined, that is, the corresponding relationship between the initial voltage of the first frame holding frame of the current picture and the display voltage of the first frame holding frame of the current picture is determined, the display voltage of the first frame holding frame of the current picture can be determined according to the initial voltage of the first frame holding frame of the current picture. In this way, the display voltage of the first frame holding frame after adjustment and compensation can be quickly obtained, ensuring the timeliness of eliminating the flickering screen.

[0096] It should be understood that the severity of the brightness mutation problem corresponding to different display frequencies of the previous screen and the current screen will also be different. Correspondingly, for the same display frequency of the previous screen and the current screen, the corresponding brightness mutation will change with different initial voltages. In the embodiment of the present application, by pre-constructing the corresponding relationship between the display frequency of the previous screen and the display frequency of the current screen and the first corresponding relationship, the brightness mutation degree corresponding to the display frequency of different previous screens and the display frequency of the current screen can be quantified, which provides a basis for determining the appropriate display voltage during application, ensures the effective improvement of the flickering screen, and improves the product yield.

[0097] In some embodiments, in order to further eliminate the screen flickering phenomenon, the display method may also include: displaying a holding frame after the first frame holding frame of the current picture, the holding frame display voltage of at least one frame after the first frame holding frame is at least partially different from the display voltage of the write frame of the current picture, and the holding frame of at least one frame is set continuously with the first frame holding frame.

[0098] It should be noted that, with respect to the screen flickering phenomenon, the picture with sudden brightness change may be the first frame holding frame, or may be the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame.

[0099] Correspondingly, the display voltage of at least one frame after the first frame holding frame is set to be at least partially different from the display voltage of the write frame of the current picture, that is, compensatory adjustment of the display voltage of the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame is achieved, which can further eliminate screen flickering and improve the display effect.

[0100] Specifically, when compensating and adjusting the display voltage of at least one frame after the first frame holding frame, the display voltage of at least one frame holding frame can be set to be the same as the display voltage of the first frame holding frame, so that the display effects of the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are the same, avoiding the occurrence of screen flickering.

[0101] In addition, to ensure the display effect of the displayed picture, the initial voltage of the first frame of the current picture is kept the same as the display voltage of the write frame of the current picture.

[0102] After the display voltage of the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are compensated and adjusted, the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are displayed based on the display voltage after the compensation adjustment, and for the holding frame after at least one frame holding frame, the holding frame after at least one frame holding frame is displayed at the initial voltage. In this way, while achieving frequency reduction, the occurrence of screen flickering can be avoided to ensure the display effect.

[0103] In some embodiments, Figure 3 As shown, the method for establishing the first corresponding relationship may include the following implementation steps:

[0104] S301, displaying a first picture at a first frequency, and displaying a second picture at a second frequency, wherein the second picture is adjacent to the first picture and is located after the first picture, the second frequency is less than the first frequency, and an initial voltage of each pixel of the second picture corresponds to a uniform grayscale value.

[0105] The second frequency is less than the first frequency, that is, the second picture is displayed at a lower frequency relative to the first picture. The uniform grayscale value refers to the grayscale value of the second picture displayed as a pure color picture. Generally, a pure color picture refers to a picture in which only one sub-pixel of each pixel emits light, and the light emitted by the sub-pixels of each pixel is the same color. The initial voltage of the second picture corresponds to the uniform grayscale value, which can facilitate subsequent testing.

[0106] Of course, in the embodiment of the present application, the initial voltage of the second picture corresponds to a uniform grayscale value, but the present application is not limited thereto. In some other implementations, the initial voltage of the second picture may also correspond to a non-uniform grayscale value.

[0107] S302 , adjusting the display voltage of the first frame of the second picture to maintain the frame, adjusting the brightness of the first frame of the second picture to maintain the frame to a standard grayscale value, and recording the corresponding display voltage.

[0108] The brightness of the first frame of the second picture is adjusted to a standard grayscale value, and the corresponding display voltage is recorded, that is, the voltage after the initial voltage is compensated and adjusted, thereby collecting the actual brightness of the first frame of the second picture and providing data support for establishing the first corresponding relationship.

[0109] S303 , testing the corresponding display voltage of the second picture under a plurality of standard grayscale values.

[0110] That is, the actual brightness collection of the first frame of the second picture under multiple standard grayscale values ​​is achieved.

[0111] S304: Establish a first corresponding relationship between the initial voltage and the display voltage according to a plurality of standard grayscale values ​​and the corresponding display voltages.

[0112] The first corresponding relationship obtained in this way reflects the corresponding relationship between the initial voltage and the voltage after the initial voltage is compensated and adjusted, which greatly facilitates the subsequent rapid compensation adjustment of the initial voltage.

[0113] In some embodiments, Figure 4 As shown, the above step S304 may specifically include the following steps:

[0114] S3041, testing the display voltage corresponding to the second picture under all standard grayscale values.

[0115] S3042: Establish a first corresponding relationship between the initial voltage and the display voltage according to all standard grayscale values ​​and the corresponding display voltages.

[0116] In this way, the display voltage corresponding to the initial voltage at each standard grayscale value can be obtained, further improving the comprehensiveness and accuracy of the compensation adjustment.

[0117] In some implementations, the above step S304 may also be performed by fitting a first corresponding relationship between the initial voltage and the display voltage according to a plurality of standard grayscale values.

[0118] During implementation, after obtaining the display voltages corresponding to the initial voltages at multiple standard grayscale values, a fitting formula can be established to fit the initial voltages at multiple standard grayscale values ​​and their corresponding display voltages, thereby obtaining the display voltages corresponding to the initial voltages at each standard grayscale value.

[0119] Specifically, when the first corresponding relationship between the initial voltage and the display voltage is fitted according to multiple standard grayscale values, the values ​​of k and b in y=kx+b can be fitted according to the formula y=kx+b and multiple standard grayscale values; then the values ​​of other grayscales are tested, and it is detected whether y=kx+b meets the preset value. If not, the values ​​of k and b are adjusted until y=kx+b meets the preset value; under the condition that y=kx+b meets the preset value, y=kx+b is determined as the first corresponding relationship at the current frequency.

[0120] Preferably, the first corresponding relationships at different first frequencies and second frequencies are tested to obtain the first corresponding relationships at different frequencies.

[0121] Among them, y=kx+b is the gamma voltage compensation formula. In the formula, x represents the initial voltage value; y represents the display voltage value; k represents the compensation coefficient; and b represents the compensation voltage adjustment amount. Since the initial voltage values ​​under different standard grayscale values ​​are different, for multiple different standard grayscale values, the initial voltages of multiple first frame holding frames and the display voltages of the first frame holding frames can be obtained, and they are respectively brought into the gamma voltage compensation formula for fitting, and the compensation coefficient k and the compensation voltage adjustment amount b can be determined, that is, the corresponding relationship between the initial voltage and the display voltage can be determined. It should be noted that the fitting can be any fitting method, such as curve fitting, least squares fitting, etc., which is not limited here.

[0122] In some embodiments, in order to further reduce the screen flickering phenomenon, the above-mentioned response to the display frequency of the current picture being less than the preset frequency, determining the display voltage corresponding to the first frame of the current picture to maintain the frame may also include: in response to the display frequency of the current picture being less than the preset frequency, and the display frequency of the current picture being equal to the display frequency of the previous picture of the current picture, determining the display voltage corresponding to the first frame of the current picture to maintain the frame.

[0123] When implementing, Figure 5 As shown, in response to the display frequency of the current picture being less than the preset frequency and the display frequency of the current picture being equal to the display frequency of the picture before the current picture, determining the display voltage corresponding to the first frame holding frame of the current picture may specifically include the following steps:

[0124] S501 . Determine a second corresponding relationship according to a display frequency of a current picture, where the second corresponding relationship is a corresponding relationship between an initial voltage of a first frame holding frame of the current picture and a display voltage.

[0125] Specifically, the correspondence between the display frequency of the previous picture and the display frequency of the current picture and the second correspondence can be pre-constructed so that the display frequencies of different current pictures have their unique corresponding second correspondences, thereby laying a foundation for obtaining a more accurate second correspondence.

[0126] After constructing the correspondence between the display frequency of the current picture and the second correspondence, the corresponding second correspondence can be determined according to the acquired display frequency of the current picture, thereby laying the foundation for further acquiring a more accurate display voltage of the first frame holding frame of the current picture.

[0127] It should be noted that the initial voltage of the first frame holding frame is the voltage before the first frame holding frame is compensated and adjusted, and the display voltage is the voltage after the initial voltage of the first frame holding frame is compensated and adjusted.

[0128] S502 , determining a display voltage of the first frame holding frame of the current picture according to the initial voltage of the first frame holding frame of the current picture and the second corresponding relationship.

[0129] After determining the second corresponding relationship, that is, determining the corresponding relationship between the initial voltage of the first frame holding frame of the current picture and the display voltage of the first frame holding frame of the current picture, the display voltage of the first frame holding frame of the current picture can be determined based on the second corresponding relationship according to the initial voltage of the first frame holding frame of the current picture. In this way, the display voltage of the first frame holding frame after adjustment and compensation can be quickly obtained to ensure the timeliness of eliminating the flickering screen.

[0130] It should be understood that the severity of the brightness mutation problem corresponding to different display frequencies of the current picture will also be different. Accordingly, for the display frequency of the same current picture, the corresponding brightness mutation will change with different initial voltages. In the embodiment of the present application, by pre-constructing the corresponding relationship between the display frequency of the current picture and the second corresponding relationship, the brightness mutation degree corresponding to the display frequencies of different current pictures can be quantified, which provides a basis for determining the appropriate display voltage during application, ensures effective improvement of the flickering screen, and improves the product yield.

[0131] In some embodiments, in order to further eliminate the screen flickering phenomenon, the display method may also include: displaying a holding frame after the first frame holding frame of the current picture, the holding frame display voltage of at least one frame after the first frame holding frame is at least partially different from the display voltage of the write frame of the current picture, and the holding frame of at least one frame is set continuously with the first frame holding frame.

[0132] It should be noted that, with respect to the screen flickering phenomenon, the picture with sudden brightness change may be the first frame holding frame, or may be the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame.

[0133] Correspondingly, the display voltage of at least one frame after the first frame holding frame is set to be at least partially different from the display voltage of the write frame of the current picture, that is, compensatory adjustment of the display voltage of the display picture with sudden brightness changes in the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame is achieved, which can further eliminate screen flickering and improve the display effect.

[0134] Specifically, when compensating and adjusting the display voltage of at least one frame after the first frame holding frame, the display voltage of at least one frame holding frame can be set to be the same as the display voltage of the first frame holding frame, so that the display effects of the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are the same, avoiding the occurrence of screen flickering.

[0135] In addition, to ensure the display effect of the displayed picture, the initial voltage of the first frame of the current picture is kept the same as the display voltage of the write frame of the current picture.

[0136] After the display voltage of the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are compensated and adjusted, the first frame holding frame and one or more frames after the first frame holding frame and continuous with the first frame holding frame are displayed based on the display voltage after the compensation adjustment, and for the holding frame after at least one frame holding frame, the holding frame after at least one frame holding frame is displayed at the initial voltage. In this way, while achieving frequency reduction, the occurrence of screen flickering can be avoided to ensure the display effect.

[0137] In some embodiments, Figure 6 As shown, the method for establishing the second corresponding relationship may include the following implementation steps:

[0138] S601 , displaying a first frame and a second frame at a first frequency, wherein the second frame is adjacent to the first frame and is located after the first frame, and an initial voltage of each pixel of the second frame corresponds to a uniform grayscale value.

[0139] The first frame and the second frame are displayed at a first frequency, that is, the first frame and the second frame maintain the same first frequency.

[0140] S602 , adjusting the display voltage of the first frame of the second picture to maintain the frame, adjusting the brightness of the first frame of the second picture to maintain the frame to a standard grayscale value, and recording the corresponding display voltage.

[0141] The brightness of the first frame of the second picture is adjusted to a standard grayscale value, and the corresponding display voltage is recorded, that is, the voltage after the initial voltage is compensated and adjusted, thereby collecting the actual brightness of the first frame of the second picture and providing data support for establishing a second corresponding relationship.

[0142] S603 , testing the corresponding display voltage of the second picture under a plurality of standard grayscale values.

[0143] That is, the actual brightness collection of the first frame of the second picture under multiple standard grayscale values ​​is achieved.

[0144] S604: Establish a second corresponding relationship between the initial voltage and the display voltage according to a plurality of standard grayscale values ​​and the corresponding display voltages.

[0145] The second corresponding relationship obtained in this way reflects the corresponding relationship between the initial voltage and the voltage after the initial voltage is compensated and adjusted, which provides great convenience for the subsequent rapid compensation adjustment of the initial voltage.

[0146] In some embodiments, Figure 7 As shown, the above step S604 may specifically include the following implementation steps:

[0147] S6041, testing the corresponding display voltage of the second picture under all standard grayscale values.

[0148] S6042: Establish a second corresponding relationship between the initial voltage and the display voltage according to all standard grayscale values ​​and the corresponding display voltages.

[0149] In this way, the display voltage corresponding to the initial voltage at each standard grayscale value can be obtained, further improving the comprehensiveness and accuracy of the compensation adjustment.

[0150] In some implementations, the above step S604 may also be performed by fitting a second corresponding relationship between the initial voltage and the display voltage according to a plurality of standard grayscale values.

[0151] During implementation, after obtaining the display voltages corresponding to the initial voltages at multiple standard grayscale values, a fitting formula can be established to fit the initial voltages at multiple standard grayscale values ​​and their corresponding display voltages, thereby obtaining the display voltages corresponding to the initial voltages at each standard grayscale value.

[0152] Specifically, when the second corresponding relationship between the initial voltage and the display voltage is fitted according to multiple standard grayscale values, the values ​​of k and b in y=kx+b can be fitted according to the formula y=kx+b and multiple standard grayscale values; then the values ​​of other grayscales are tested, and it is detected whether y=kx+b meets the preset value. If not, the values ​​of k and b are adjusted until y=kx+b meets the preset value; under the condition that y=kx+b meets the preset value, y=kx+b is determined as the second corresponding relationship at the current frequency.

[0153] Preferably, the second corresponding relationships at different first frequencies are tested to obtain the second corresponding relationships at different frequencies.

[0154] Among them, y=kx+b is the gamma voltage compensation formula. In the formula, x represents the initial voltage value; y represents the display voltage value; k represents the compensation coefficient; and b represents the compensation voltage adjustment amount. Since the initial voltage values ​​under different standard grayscale values ​​are different, for multiple different standard grayscale values, the initial voltages of multiple first frame holding frames and the display voltages of the first frame holding frames can be obtained, and they are respectively brought into the gamma voltage compensation formula for fitting, and the compensation coefficient k and the compensation voltage adjustment amount b can be determined, that is, the corresponding relationship between the initial voltage and the display voltage can be determined. It should be noted that the fitting can be any fitting method, such as curve fitting, least squares fitting, etc., which is not limited here.
