[0073] Unless otherwise defined, technical or scientific terms used in the present specification are intended to have the meanings commonly understood by one of ordinary skill in the art to which the present specification pertains. The terms "first", "second", and the like, as used in the present specification, do not imply any order, quantity, or importance, but are used to avoid confusion with one another.

[0074] Unless otherwise required by context, "plurality" will mean "at least two" and "includes" will mean "comprises, and "including," will mean "including, but not limited to." The terminology "one embodiment," "some embodiments," "an exemplary embodiment," "an example," "a specific example," or "some examples," as used herein, is intended to indicate that a particular feature, structure, material, or characteristic is included in at least one embodiment or example of the present disclosure, and is not necessarily included in all embodiments or examples of the present disclosure. The

[0075] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

[0076] Traditional 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.) are displayed at a fixed refresh rate, such as 60 Hz or 120 Hz. In other words, the refresh rate of the display panel in the working state remains unchanged regardless of the application scenario.

[0077] In recent years, with the rapid development of display technology, low-power display panels have become an important development trend, and high-low frequency switching as an important technical means to reduce the power consumption of display panels 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 maintaining the frame, for example, the preset frequency of the display panel is 120 Hz, and the display frequency of the display panel is 30 Hz, a picture will be displayed in the form of a write-in frame and three maintenance frames. It should be noted that the preset frequency is generally the highest frequency of the display panel, wherein the write-in frame writes data and is displayed, and the write-in frame is followed by three maintenance frames, which maintain the display of the data written in the write-in frame. The write-in frame and the maintenance frame will have a black insertion phase to ensure the display effect. Generally, the write-in frame is only one frame, and the maintenance frame can have multiple frames. The inventors have found that the display mode of reducing the frequency will cause the display panel to flash, resulting in a decrease in user experience.

[0078] To this end, the application provides a solution capable of effectively improving the flash screen problem. By adjusting the display voltage of the first frame holding frame of the current picture, the display voltage of the first frame holding frame after the write frame is different from the display voltage of the write frame, so as to adjust the voltage of the first frame holding frame after the write frame, that is, adjust the brightness of the first frame holding frame after the write frame, so that the display effect of the first frame holding frame is basically the same as that of the write frame, avoiding the flash screen problem of the display panel, and improving the display effect.

[0079] Specifically, as an optional implementation of the disclosure, the application provides a display method, as shown in the following formula: Figure 1 The display method can specifically include the following implementation steps:

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

[0081] For example, the preset frequency is 120Hz, and the display frequency of the current picture is 60Hz, which is less than 120Hz, so 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 being less than the preset frequency can be receiving a refresh rate switching instruction carrying the display frequency of the current picture, and correspondingly, 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 being less than the preset frequency is the 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 write frame of the current picture, that is, the display voltage corresponding to the first frame holding frame of the current picture is the voltage after compensating and adjusting the reference voltage corresponding to the first frame holding frame of the current picture, which realizes the adjustment of the brightness of the first frame holding frame after the write frame, so that the display effect of the first frame holding frame is basically the same as that of the write frame, avoiding the occurrence of the flash screen phenomenon.

[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] Displaying the first frame holding frame of the current picture by using the display voltage of the first frame holding frame after compensating and adjusting can avoid the case that the display voltage of the first frame holding frame and the display voltage of the write frame have too large pressure difference, thereby avoiding the flash screen phenomenon caused by frequency reduction.

[0086] In this embodiment, in response to the display frequency of the current frame being less than a preset frequency, the display voltage corresponding to the first held frame of the current frame is determined. The display voltage of the first held frame of the current frame is at least partially different from the display voltage of the written frame of the current frame. Then, the first held frame of the current frame is displayed based on its display voltage. Thus, by adjusting the display voltage of the first held frame of the current frame to make it different from the display voltage written in the written frame, the voltage of the first held frame after the written frame can be adjusted, which also adjusts the brightness of the first held frame after the written frame. This ensures that the display effect of the first held frame is essentially the same as that of the written frame, avoiding screen flickering and improving the display effect.

[0087] In some implementations, in order to further reduce screen flickering, the above-mentioned determination of the display voltage corresponding to the first hold frame of the current frame in response to the display frequency of the current screen being less than the preset frequency may specifically include: determining the display voltage corresponding to the first hold frame of the current screen in response to the display frequency of the current screen being less than the preset frequency and the display frequency of the current screen being different from the display frequency of the previous screen.

[0088] The display frequency of the current frame can be less than the display frequency of the previous frame.

[0089] When implementing, such as Figure 2 As shown, the above response to the current screen's display frequency being less than a preset frequency, and the current screen's display frequency being different from the previous screen's display frequency, determines the display voltage corresponding to the first hold frame of the current screen. Specifically, this may include the following steps:

[0090] S201. Based on the display frequency of the previous frame and the display frequency of the current frame, determine the first correspondence relationship. The first correspondence relationship is the correspondence between the initial voltage of the first frame of the current frame and the display voltage.

[0091] Specifically, a correspondence between the display frequency of the previous frame and the display frequency of the current frame and the first correspondence can be pre-constructed, so that each display frequency of the previous frame and the display frequency of the current frame has its own unique first correspondence, thus laying the foundation for obtaining a more accurate first correspondence.

[0092] After establishing the correspondence between the display frequency of the previous frame and the display frequency of the current frame and the first correspondence, the corresponding first correspondence can be determined based on the obtained display frequency of the previous frame and the display frequency of the current frame. This lays the foundation for obtaining a more accurate display voltage of the first frame of the current frame.

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

[0094] S202, determining the display voltage of the first frame holding frame of the current frame according to the initial voltage of the first frame holding frame of the current frame and the first correspondence.

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

[0096] It should be understood that the severity of the brightness mutation problem corresponding to different display frequencies of the previous frame and the display frequency of the current frame is also different, and accordingly, the brightness mutation corresponding to the same display frequency of the previous frame and the display frequency of the current frame will change with the initial voltage. In the embodiments of the present application, by pre-constructing the correspondence between the display frequency of the previous frame and the display frequency of the current frame and the first correspondence, the brightness mutation degree corresponding to the display frequency of the previous frame and the display frequency of the current frame can be quantified, which provides a basis for determining a suitable display voltage in application, ensures effective improvement of the flash screen, and improves product yield.

[0097] In some embodiments, in order to further eliminate the flash screen phenomenon, the display method can further include: displaying a holding frame after the first frame holding frame of the current frame, the display voltage of the holding frame at least one frame after the first frame holding frame being at least partially different from the display voltage of the write-in frame of the current frame, and the holding frame at least one frame being continuously arranged with the first frame holding frame.

[0098] It should be noted that for the phenomenon of flash screen, the picture with brightness mutation can be the first frame holding frame, or 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 the holding frame 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-in frame of the current frame, that is, the compensation 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 realized, which can further eliminate the flash screen and improve the display effect.

[0100] Specifically, when the display voltage of the at least one frame of holding frame after the first frame of holding frame is adjusted, the display voltage of the at least one frame of holding frame can be set to be the same as the display voltage of the first frame of holding frame, so that the display effect of the first frame of holding frame and the one or more frames after the first frame of holding frame and continuous with the first frame of holding frame is the same, and the occurrence of the screen flashing phenomenon is avoided.

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

[0102] After the compensation adjustment of the display voltage of the first frame of holding frame and the one or more frames after the first frame of holding frame and continuous with the first frame of holding frame, the first frame of holding frame and the one or more frames after the first frame of holding frame and continuous with the first frame of holding frame are displayed based on the adjusted display voltage, and the holding frame after the at least one frame of holding frame is displayed with the initial voltage. In this way, while realizing the frequency reduction, the occurrence of the screen flashing phenomenon is avoided, and the display effect is ensured.

[0103] In some embodiments, as shown in Figure 3 The method for establishing the first corresponding relationship can include the following implementation steps:

[0104] S301, display a first picture at a first frequency and display a second picture at a second frequency, 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 the initial voltage of each pixel of the second picture corresponds to a uniform gray scale value.

[0105] The second frequency is less than the first frequency, that is, the display of the second picture relative to the first picture occurs frequency reduction. The uniform gray scale value refers to the gray scale value of the second picture displayed as a solid color picture. Generally, a solid color picture refers to a picture in which each pixel has only one sub-pixel emitting light, and the color of the light emitted by each pixel is the same. The initial voltage of the second picture corresponds to the uniform gray scale value, which can provide convenience for subsequent testing.

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

[0107] S302, adjust the display voltage of the first frame of holding frame of the second picture, adjust the brightness of the first frame of holding frame of the second picture to a standard gray scale value, and record the corresponding display voltage.

[0108] The brightness of the first frame holding frame of the second picture is adjusted to a standard gray scale value, and the corresponding display voltage is recorded, that is, the voltage after compensation and adjustment of the initial voltage is recorded, so that the actual brightness of the first frame holding frame of the second picture is collected, and data support is provided for establishing the first corresponding relationship.

[0109] S303, test the corresponding display voltage of the second picture under a plurality of standard gray scale values.

[0110] That is, the actual brightness of the first frame holding frame of the second picture under a plurality of standard gray scale values is collected.

[0111] S304, according to the plurality of standard gray scale values and the corresponding display voltage, a first corresponding relationship between the initial voltage and the display voltage is established.

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

[0113] In some embodiments, as shown in Figure 4 The step S304 can include the following steps:

[0114] S3041, test the corresponding display voltage of the second picture under all standard gray scale values.

[0115] S3042, according to all standard gray scale values and the corresponding display voltage, a first corresponding relationship between the initial voltage and the display voltage is established.

[0116] In this way, the display voltage corresponding to the initial voltage under each standard gray scale value can be obtained, and the comprehensiveness and accuracy of compensation and adjustment are further improved.

[0117] In some embodiments, the step S304 can also be that a first corresponding relationship between the initial voltage and the display voltage is fitted according to a plurality of standard gray scale values.

[0118] In implementation, after obtaining the display voltage corresponding to the initial voltage under a plurality of standard gray scale values, the initial voltage and the corresponding display voltage under the plurality of standard gray scale values can be fitted by establishing a fitting formula, so that the display voltage corresponding to the initial voltage under each standard gray scale value is obtained.

[0119] Specifically, in the process of fitting the first corresponding relationship between the initial voltage and the display voltage according to the plurality of standard gray scale values, firstly, the values of k and b in y=kx+b can be fitted according to the formula y=kx+b and the plurality of standard gray scale values; then, the values of other gray scales are tested, and whether y=kx+b conforms to the preset value is detected; if not, the values of k and b are adjusted until y=kx+b conforms to the preset value; and under the condition that y=kx+b conforms to the preset value, y=kx+b is determined as the first corresponding relationship under the current frequency.

[0120] Preferably, the first corresponding relationship under different frequencies is obtained by testing the first corresponding relationship under different first frequencies and second frequencies.

[0121] 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 gray scale values are different, for a plurality of different standard gray scale values, the initial voltage of the first frame holding frame and the display voltage of the first frame holding frame can be obtained, which are respectively brought into the gamma voltage compensation formula for fitting, so that the compensation coefficient k and the compensation voltage adjustment amount b are determined, that is, the corresponding relationship between the initial voltage and the display voltage is determined. It should be noted that the fitting can be any fitting method, such as curve fitting, least square fitting, etc., which is not limited herein.

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

[0123] In implementation, as shown in Figure 5 the above-mentioned determining the display voltage corresponding to the first frame holding frame of the current picture 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, can specifically include the following steps:

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

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

[0126] After the corresponding relationship between the display frequency of the current picture and the second corresponding relationship is constructed, the corresponding second corresponding relationship can be determined according to the obtained display frequency of the current picture, thereby laying a foundation for further obtaining 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 compensation adjustment of the first frame holding frame, and the display voltage is the voltage after compensation adjustment of the initial voltage of the first frame holding frame.

[0128] S502, determining the 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 the second 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 based on the second corresponding relationship and 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, and the timeliness of eliminating the flash screen can be ensured.

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

[0131] In some embodiments, in order to further eliminate the flash screen phenomenon, the display method can further include: displaying the holding frame after the first frame holding frame of the current picture, the display voltage of the holding frame at least one frame after the first frame holding frame is at least partially different from the display voltage of the written frame of the current picture, and the holding frame at least one frame is continuously arranged with the first frame holding frame.

[0132] It should be noted that for the phenomenon of flash screen, the picture with brightness mutation can be the first frame holding frame, or 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 the first frame holding frame and at least one frame after the first frame holding frame is set to be at least partially different from the display voltage of the writing frame of the current picture, that is, the display voltage of the display picture with luminance mutation 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 compensated and adjusted, which can further eliminate the screen flashing and improve the display effect.

[0134] Specifically, when the display voltage of at least one frame after the first frame holding frame is compensated and adjusted, the display voltage of the 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 effect 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 the same, and the screen flashing phenomenon is avoided.

[0135] In addition, to ensure the display effect of the display picture, the initial voltage of the first frame holding frame of the current picture is the same as the display voltage of the writing 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 is 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 compensated and adjusted display voltage, and the holding frame after the at least one frame holding frame is displayed with the initial voltage. In this way, while the frequency is reduced, the screen flashing is avoided, and the display effect is ensured.

[0137] In some embodiments, as shown in Figure 6 The method for establishing the second corresponding relationship can include the following implementation steps:

[0138] S601, display a first picture and a second picture at a first frequency, the second picture is adjacent to the first picture and located after the first picture, and the initial voltage of each pixel of the second picture corresponds to a uniform gray scale value.

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

[0140] S602, adjust the display voltage of the first frame holding frame of the second picture, adjust the luminance of the first frame holding frame of the second picture to a standard gray scale value, and record the corresponding display voltage.

[0141] The luminance of the first frame holding frame of the second picture is adjusted to a standard gray scale value, and the corresponding display voltage is recorded, that is, the voltage after the initial voltage is compensated and adjusted is recorded, which realizes the collection of the actual luminance of the first frame holding frame of the second picture and provides data support for establishing the second corresponding relationship.

[0142] S603, test the corresponding display voltage of the second picture under the plurality of standard gray scale values.

[0143] That is, the actual brightness collection of the first frame of the second picture under the plurality of standard gray scale values is realized.

[0144] S604, establish the second corresponding relationship between the initial voltage and the display voltage according to the plurality of standard gray scale values and the corresponding display voltage.

[0145] The second corresponding relationship obtained in this way reflects the corresponding relationship between the initial voltage and the voltage after compensation adjustment of the initial voltage, and greatly facilitates the subsequent compensation adjustment of the initial voltage.

[0146] In some embodiments, as shown in Figure 7 The step S604 can specifically include the following implementation steps:

[0147] S6041, test the corresponding display voltage of the second picture under all standard gray scale values.

[0148] S6042, establish the second corresponding relationship between the initial voltage and the display voltage according to all standard gray scale values and the corresponding display voltage.

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

[0150] In some embodiments, the step S604 can also be fitting the second corresponding relationship between the initial voltage and the display voltage according to the plurality of standard gray scale values.

[0151] In implementation, after obtaining the display voltage corresponding to the initial voltage under the plurality of standard gray scale values, the initial voltage and the display voltage corresponding thereto under the plurality of standard gray scale values can be fitted by establishing a fitting formula, so as to obtain the display voltage corresponding to the initial voltage under each standard gray scale value.

[0153] Preferably, the second corresponding relationship under different frequencies is obtained by testing the second corresponding relationship under different first frequencies.

[0154] wherein y=kx+b is a gamma voltage compensation formula. In the formula, x represents an initial voltage value; y represents a display voltage value; k represents a compensation coefficient; and b represents a compensation voltage adjustment amount. Because the initial voltage values under different standard gray scale values are different, for a plurality of different standard gray scale values, the initial voltage of the first frame holding frame and the display voltage of the first frame holding frame can be obtained, which are respectively brought into the gamma voltage compensation formula for fitting, so that the compensation coefficient k and the compensation voltage adjustment amount b, that is, the corresponding relationship between the initial voltage and the display voltage, can be determined.
