[0002] The displays in existing electronic devices typically use OLED displays. To ensure display consistency, the pixels of OLED displays need to be compensated, for example, through gamma compensation.

During the display process, the matching pixel voltage is read from the lookup table according to the different gray levels of the pixels, and the OLED device is then controlled to display the image.

[0071] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0072] To address the aforementioned technical problems, this disclosure provides a display panel, a method for obtaining a pixel voltage lookup table, an electronic device, and a medium.

[0073] In one embodiment, a display panel is provided, including a monochrome subpixel array. This monochrome subpixel array may include a red subpixel array, a blue subpixel array, and a green subpixel array, and may also include a white subpixel array or a black subpixel array, etc., depending on the specific scenario. The concept of this embodiment is that at least one of the monochrome subpixel arrays of the display panel is a target array, which is composed of at least two types of subpixels arranged periodically. Any two types of subpixels have different pixel characteristics; wherein, the pixel voltages of the at least two types of subpixels are different at the same brightness.

[0074] In one example, a certain monochrome sub-pixel of the target array has two types of sub-pixels with different pixel characteristics, as shown in Table 1.

[0075] Table 1 Two types of pixel characteristics

[0076]

[0077] Referring to Table 1, when the two types of pixel characteristics of a monochrome subpixel are the same (same frequency, same DBV, same grayscale (e.g., 128), same Lv, and staggered positions (subpixel array 2 is equivalent to subpixel array 1 translated in the X and Y axes), the pixel voltage (i.e., data voltage) of the two types of subpixels takes values ​​1 and 2, respectively. Thus, this embodiment improves the color separation display effect and helps to increase the lifespan and efficiency of subpixels by setting the pixel voltages of at least two types of pixel characteristics for the monochrome subpixel array.

[0078] Based on the above concept, this embodiment provides an example of the arrangement of a sub-pixel array in a display panel, including:

[0079] In one example, the target array includes each type of monochrome subpixel array, and each monochrome subpixel array consists of two types of subpixels with different pixel characteristics. In another example, the target array includes each type of monochrome subpixel array, and each monochrome subpixel array consists of three or more types of subpixels with different pixel characteristics. It is understood that the types of pixel characteristics included in the monochrome subpixel array can be selected according to the specific scenario, and the corresponding scheme falls within the protection scope of this disclosure.

[0080] When the display panel includes RGB three-color sub-pixel arrays, taking as an example that the target array includes each type of color sub-pixel array and each color sub-pixel array is composed of two types of sub-pixels with different pixel characteristics, the target array includes RGB three-color sub-pixel arrays, and each color sub-pixel array is provided with two types of sub-pixels with different pixel characteristics. See [link to relevant documentation]. Figure 1 The green subpixel array includes two types of subpixels with different pixel characteristics, namely G1 and G2; the red subpixel array includes two types of subpixels with different pixel characteristics, namely R1 and R2; and the blue subpixel array includes two types of subpixels with different pixel characteristics, namely B1 and B2. The arrangement of monochrome subpixels in the display panel is as follows:

[0081] Analyzing the subpixel arrangement from the row direction, there is one row of green subpixels, one row of red and blue subpixels; one row of green subpixels, one row of red and blue subpixels; and so on.

[0082] Analyzing the subpixel arrangement from the column direction, there is one column of green subpixels, one column of red and blue subpixels; one column of green subpixels, one column of red and blue subpixels; repeat the above arrangement.

[0083] Analyzing the green sub-pixel arrangement from a single row or column, each row or column contains two types of sub-pixels, G1 and G2, with different pixel characteristics, arranged alternately.

[0084] Analyze the red and blue sub-pixels from a single row or column. In each row or column, red sub-pixels R1 and R2 of two types of pixel characteristics are arranged alternately, as well as blue sub-pixels B1 and B2 of two types of pixel characteristics. The sub-pixels of the above four types of pixel characteristics are arranged in sequence as a unit, such as B2 / R1 / B1 / R2, and then the above arrangement unit is repeated.

[0085] It should be noted that, Figure 1 The example illustrates a scheme where each monochrome subpixel array has subpixels with two pixel characteristics. In some possible examples, each monochrome subpixel array can have subpixels with three or more pixel characteristics; the corresponding arrangements can be found in [reference needed]. Figure 1 The examples provided fall within the protection scope of this disclosure.

[0086] In one example, the target array is a combination of two monochrome sub-pixel arrays; and each of the two monochrome sub-pixel arrays consists of two types of sub-pixels with different pixel characteristics. In another example, the target array is a combination of two monochrome sub-pixel arrays; and each of the two monochrome sub-pixel arrays consists of three or more types of sub-pixels with different pixel characteristics.

[0087] When the display panel includes three monochrome sub-pixel arrays of RGB, taking two of the three monochrome sub-pixel arrays of RGB as an example, such as the two sub-pixel arrays mentioned above being RG monochrome sub-pixel array, RB monochrome sub-pixel array or GB monochrome sub-pixel array; and each monochrome sub-pixel array in the target array is provided with sub-pixels of two types of pixel characteristics.

[0088] Taking a target array including an RB monochrome sub-pixel array as an example, see [link to relevant documentation]. Figure 2 The green subpixel array contains only two types of subpixels G with different pixel characteristics; the red subpixel array includes two types of subpixels R1 and R2 with different pixel characteristics; and the blue subpixel array includes two types of subpixels B1 and B2 with different pixel characteristics. The arrangement of monochrome subpixels within the display panel is as follows:

[0089] Analyzing the subpixel arrangement from the row direction, there is one row of green subpixels, one row of red and blue subpixels; one row of green subpixels, one row of red and blue subpixels; and so on.

[0090] Analyzing the subpixel arrangement from the column direction, there is one column of green subpixels, one column of red and blue subpixels; one column of green subpixels, one column of red and blue subpixels; repeat the above arrangement.

[0091] Analyze the red and blue sub-pixels from a single row or column. In each row or column, red sub-pixels R1 and R2 of two types of pixel characteristics are arranged alternately, as well as blue sub-pixels B1 and B2 of two types of pixel characteristics. The sub-pixels of the above four types of pixel characteristics are arranged in sequence as a unit, such as B2 / R1 / B1 / R2, and then the above arrangement unit is repeated.

[0092] It should be noted that, Figure 2 The example illustrates a scheme where each monochrome subpixel array has subpixels with two pixel characteristics. In some possible examples, each monochrome subpixel array can have subpixels with three or more pixel characteristics; the corresponding arrangements can be found in [reference needed]. Figure 2 The examples provided fall within the protection scope of this disclosure.

[0093] In another example, when the display panel includes RGB monochrome sub-pixel arrays, the target array includes one of the RGB monochrome sub-pixel arrays, such as a red sub-pixel array, a green sub-pixel array, or a blue sub-pixel array; and the target array has sub-pixels with two or more pixel characteristics. For example, if the target array includes a red sub-pixel array, see [link to example]. Figure 3 The green subpixel array contains only one type of subpixel, G, with pixel characteristics. The red subpixel array includes two types of subpixels with different pixel characteristics, namely R1 and R2. The blue subpixel array contains only one type of subpixel, namely B. The arrangement of monochrome subpixels within the display panel is as follows:

[0094] Analyzing the subpixel arrangement from the row direction, there is one row of green subpixels, one row of red and blue subpixels; one row of green subpixels, one row of red and blue subpixels; and so on.

[0095] Analyzing the subpixel arrangement from the column direction, there is one column of green subpixels, one column of red and blue subpixels; one column of green subpixels, one column of red and blue subpixels; repeat the above arrangement.

[0096] Analyze the red and blue sub-pixels from a single row or column. In each row or column, blue sub-pixels B1 and B2 with two types of pixel characteristics are arranged alternately. Then, a red sub-pixel is inserted simultaneously before or after two adjacent blue sub-pixels B1 and B2, i.e., B2 / R / B1 / R, or R / B1 / R / B2, etc. Then repeat the above arrangement unit.

[0097] It should be noted that, Figure 2 The example illustrates a scheme where each monochrome subpixel array has subpixels with two pixel characteristics. In some possible examples, each monochrome subpixel array can have subpixels with three or more pixel characteristics; the corresponding arrangements can be found in [reference needed]. Figure 2 The examples provided fall within the protection scope of this disclosure.

[0098] In another example, when the display panel includes RGB monochrome sub-pixel arrays, the target array also includes RGB monochrome sub-pixel arrays; and each of the RGB monochrome sub-pixel arrays has at least two arrays with different pixel characteristics. For example, the green sub-pixel array may include sub-pixels G1, G2, and G3 with three types of pixel characteristics; the red sub-pixel array may include two types of sub-pixels R1 and R2 with different pixel characteristics; and the blue sub-pixel array may include two types of sub-pixels B1 and B2 with different pixel characteristics. See [reference needed]. Figure 4 The arrangement of monochrome subpixels within the display panel is as follows:

[0099] Analyzing the subpixel arrangement from the row direction, there is one row of green subpixels, one row of red and blue subpixels; one row of green subpixels, one row of red and blue subpixels; and so on.

[0100] Analyzing the subpixel arrangement from the column direction, there is one column of green subpixels, one column of red and blue subpixels; one column of green subpixels, one column of red and blue subpixels; repeat the above arrangement.

[0101] Analyzing the green sub-pixel arrangement from a single row or column, the sub-pixels G1, G2, and G3 of the three pixel characteristics are arranged alternately within each row or column.

[0102] Analyze the red and blue sub-pixels from a single row or column. In each row or column, red sub-pixels R1 and R2 of two types of pixel characteristics are arranged alternately, along with blue sub-pixels B1 and B2 of two types of pixel characteristics. The sub-pixels of the above four types of pixel characteristics are arranged sequentially as a unit, such as B2 / R1 / B1 / R2 or R2 / B2 / R1 / B1, etc., and then the above arrangement unit is repeated.

[0103] It should be noted that, Figure 4 The example illustrates a scheme where a target array includes subpixel arrays with three pixel characteristics, mixed with other subpixel arrays each containing two pixel characteristics. In some possible examples, each monochrome subpixel array can have two or more pixel characteristics, and multiple monochrome subpixel arrays can be mixed with subpixels of different numbers of pixel characteristics. For example, a red subpixel array may include subpixels with three pixel characteristics, a green subpixel array may include subpixels with three pixel characteristics, and a blue subpixel array may include subpixels with two pixel characteristics, etc. The corresponding arrangement can be found in [reference needed]. Figure 4 The examples provided fall within the protection scope of this disclosure.

[0104] based on Figures 1 to 4The illustrated subpixel arrangement scheme discloses a red subpixel array and a blue subpixel array arranged in rows and columns; furthermore, any row of red subpixels in the red subpixel array is spaced apart from the blue subpixels in the same row of the blue subpixel array. Additionally, the monochromatic subpixel array includes green subpixels arranged in rows and columns, with the rows of green subpixels spaced apart from the rows of red subpixels, or the columns of green subpixels spaced apart from the columns of red subpixels; or, in other words, a row of subpixels composed of a mixture of red and blue subpixels is provided between adjacent rows of green subpixels.

[0105] In one embodiment, the display panel further includes a pixel driving module (DDIC) electrically connected to each sub-pixel. The pixel driving module stores a pixel voltage lookup table, which includes a mapping relationship between pixel grayscale and pixel voltage; the pixel voltage lookup table shows that at least two types of sub-pixels have different pixel voltages at the same brightness.

[0106] It should be noted that the pixel voltage lookup table sets different pixel voltages for subpixels with different pixel characteristics at the same brightness because subpixels with different pixel characteristics have different aperture ratios. In other words, the solution disclosed in this paper improves color separation by adjusting the aperture ratio of monochrome subpixels.

[0107] In order to set different pixel voltages for at least two types of sub-pixels under the same brightness, this disclosure provides a pixel voltage lookup table acquisition method. This method can be applied to the pixel driving module DDIC or the processor of the electronic device where the display panel is located. It can be set according to the specific scenario, and the corresponding scheme falls within the protection scope of this disclosure.

[0108] In one example, one display method, see Figure 5 The process includes steps 51 to 53. In step 51, in response to the need to display an image to be displayed, a pixel voltage lookup table can be obtained. This pixel voltage lookup table is determined by the type of pixel characteristics and is used to adjust the image to be displayed. In step 52, the image to be displayed is adjusted according to the pixel voltage lookup table to obtain a target image. In step 53, the target image is displayed. In this step, the target image can be output to a display for display.

[0109] In one example, the pixel voltage lookup table can be obtained by: obtaining the types of pixel characteristics for each monochrome sub-pixel array within the target array. See also... Figures 1-4 This allows us to obtain the types of pixel characteristics of each monochrome subpixel array within the display panel. Then, we determine the pixel voltage lookup table based on the types of pixel characteristics.

[0110] In one example, the pixel voltage lookup table can be determined based on the type of pixel characteristic, see [reference needed]. Figure 6 This includes steps 61 to 63.

[0111] In step 61, when the pixel characteristics of each monochrome sub-pixel array in the target array are in a multiple relationship, the monochrome sub-pixel arrays whose pixel characteristic type is not the maximum value are virtually classified to obtain the same number of virtual pixel characteristic sub-pixels as the maximum value; the virtual pixel characteristic sub-pixels are classified according to their distance from the sub-pixel with the maximum pixel characteristic.

[0112] In this step, it can be determined whether the pixel characteristics of each monochrome sub-pixel array within the target array are in a multiple relationship.

[0113] A pixel characteristic is considered to be in a multiple relationship when its maximum value is divisible by all other values. For example, if the pixel characteristics of three monochrome RGB sub-pixel arrays are of type 2, 1, and 1 respectively, then they are in a multiple relationship. The pixel characteristic of type 2 can be a red, green, or blue sub-pixel array, and the following examples are similar. Similarly, if the pixel characteristics of three monochrome RGB sub-pixel arrays are of type 3, 1, and 1 respectively, then they are in a multiple relationship. (This is repeated three times in the original text.)

[0114] When the maximum value of a pixel characteristic cannot be divided by any other value, the relationship is determined to be a multiple. For example, if the pixel characteristics of three monochrome sub-pixel arrays of RGB are of type 3, 2, and 1 respectively, then the relationship is determined not to be a multiple. Similarly, if the pixel characteristics of three monochrome sub-pixel arrays of RGB are of type 3, 3, and 2 respectively, then the relationship is determined not to be a multiple.

[0115] In this step, when it is determined that the pixel characteristics of each monochrome sub-pixel array in the target array are in a multiple relationship, the monochrome sub-pixel arrays whose pixel characteristic type is not the maximum value can be virtually classified to obtain the same number of virtual pixel characteristic sub-pixels as the maximum value; the virtual pixel characteristic sub-pixels are classified according to their distance from the sub-pixel with the maximum value of the pixel characteristic. Taking R1 / B(1) / R2 / B(2) as an example, the first sub-pixel B(1) can be placed close to sub-pixel R1, and the second sub-pixel B(2) can be placed close to sub-pixel R2, thus virtually classifying the two sub-pixels B into sub-pixels B1' and B2'. The superscript '" indicates the sub-pixel whose pixel characteristics need to be identified, and sub-pixels B(1) and B(2) are used to distinguish the two sub-pixels B. At this time, all monochrome sub-pixels of the display panel have the same pixel characteristics, for example, 2, 2 and 2, 3, 3 and 3, etc. In other words, through virtual classification, the types of pixel characteristics of each monochrome sub-pixel are the same, all being the maximum value. For ease of explanation, the sub-pixels with virtual pixel characteristics and the sub-pixels with real pixel characteristics will be described using the same labels.

[0116] For example, the pixel characteristics of the three monochrome sub-pixel arrays of RGB are class 2, 1, and 1, respectively, such as... Figure 3 As shown, this represents a multiple relationship. In this case, two virtual pixel characteristics can be virtualized for the sub-pixels of the red sub-pixel array and two virtual pixel characteristics can be virtualized for the sub-pixels of the blue sub-pixel array. At this point, the pixel characteristics of the monochrome sub-pixel array of the display panel are of types 2, 2, and 2 respectively, as shown below. Figure 1 As shown.

[0117] In step 62, sub-pixels of various pixel characteristics in each monochrome sub-pixel array are lit sequentially, and the lit sub-pixels are adjusted according to the preset Gamma adjustment method to adjust the Gamma parameters and color coordinates of the white image, so as to obtain the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image corresponding to the white image.

[0118] In this step, for sub-pixels with multiple pixel characteristics, one type of pixel characteristic is sequentially illuminated within each monochrome sub-pixel array. In other words, one-Nth of the sub-pixels is illuminated each time, where N represents the maximum value of the pixel characteristic. For example, R1 / B1 / G1 or R2 / B2 / G2. Taking two types of pixel characteristics as an example, R1 / B1 / G1 or R2 / B2 / G2 is illuminated the first time, and R2 / B2 / G2 or R1 / B1 / G1 is illuminated the second time, meaning half of the sub-pixels are illuminated each time.

[0119] Then, according to the preset Gamma adjustment method, the Gamma parameters and color coordinates of the illuminated sub-pixels are adjusted to regulate the white image. The preset Gamma adjustment method can be selected according to the specific scenario. After the white image is adjusted, the pixel grayscale and pixel voltage of each sub-pixel of each monochrome sub-image (i.e., red sub-image, green sub-image, and blue sub-image) corresponding to the white image can be obtained and saved to the register.

[0120] In step 63, the pixel grayscale and pixel voltage of all sub-pixel arrays in the display panel are determined to form the pixel voltage lookup table.

[0121] In this step, after obtaining the pixel grayscale and pixel voltage of all sub-pixel arrays within the display panel, a pixel voltage lookup table can be obtained. It is understood that the pixel voltages of different pixel characteristics within the same monochrome sub-pixel array will differ within this lookup table.

[0122] In this example, by obtaining the pixel voltage of sub-pixels with different pixel characteristics for each type of pixel characteristic to obtain the pixel voltage lookup table, it is possible to ensure that the pixel voltage of sub-pixels with different pixel characteristics within the target array is different, and to ensure that the pixel voltage of sub-pixels outside the target array will not conflict due to multiple measurements and storage, thereby ensuring the accuracy of the pixel voltage lookup table.

[0123] In another example, the pixel voltage lookup table can be determined based on the type of pixel characteristic, see [link to relevant documentation]. Figure 7 This includes steps 71 to 74.

[0124] In step 71, when each monochrome sub-pixel array in the target array includes two types of sub-pixels with different pixel characteristics, the monochrome sub-pixel arrays with non-maximum pixel characteristic types are virtually classified to obtain two types of virtual pixel characteristic sub-pixels; the virtual pixel characteristic sub-pixels are classified according to their distance from the sub-pixel with the maximum pixel characteristic.

[0125] Understandably, the sub-pixel classification scheme in step 71 is the same as that in step 6. Please refer to the content of step 61 for details, which will not be repeated here.

[0126] In step 72, according to the one-to-one correspondence between pixel characteristics and display panels, a sub-pixel of one type of pixel characteristic of each color sub-pixel array is lit up on each group of display panels, and the lit sub-pixels are adjusted according to the preset Gamma adjustment method to adjust the Gamma parameters and color coordinates of the white image, so as to obtain the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image corresponding to the white image.

[0127] In this step, multiple sets of display panels are selected as test panels. These multiple sets of display panels are designed to have similar performance characteristics, for example, display panels from the same batch manufactured using the same process. These test panels are used to differentiate the target display panels from the target panels.

[0128] In one example, each set of display panels corresponds to a type of pixel characteristic, establishing a one-to-one correspondence between pixel characteristics and display panels. Then, on each set of display panels, sub-pixels representing one type of pixel characteristic from each color sub-pixel array are illuminated, such as R1 / B1 / G1 or R2 / B2 / G2, etc. Next, the illuminated sub-pixels are adjusted using a preset Gamma adjustment method to modify the Gamma parameters and color coordinates of the white image, obtaining the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image corresponding to the white image. In this way, each set of display panels can obtain the pixel grayscale and pixel voltage of a sub-pixel representing one type of pixel characteristic; after all display panels have been adjusted, the pixel grayscale and pixel voltage of all sub-pixels can be obtained.

[0129] In step 73, the correction coefficients of the two types of pixel characteristics of each monochrome sub-pixel in the target array are obtained based on the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image.

[0130] In this step, for the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image, the correction coefficient can be calculated based on the pixel voltage of the same monochrome sub-pixel with different pixel characteristics in the two sets of display panels. For example, the ratio of the pixel voltage of sub-pixel R1 in the first set of display panels to that of sub-pixel R2 in the second set of display panels; the ratio of the pixel voltage of sub-pixel R1 in the first set of display panels to that of sub-pixel R3 in the third set of display panels, and so on, to obtain the correction coefficient corresponding to all monochrome sub-pixels.

[0131] In step 74, the target pixel voltage of one type of pixel characteristic of each monochrome sub-pixel in the target display panel is corrected according to the correction coefficient to obtain the target pixel voltage of the sub-pixel with another type of pixel characteristic; the pixel grayscale and pixel voltage of all sub-pixel arrays of the target display panel constitute the pixel voltage lookup table.

[0132] In this step, the target pixel voltage of a type of pixel feature of the monochrome sub-pixels of the target display panel, such as the pixel voltage of R1 / B1 / G1, can be obtained as in steps 71 and 72. Then, the pixel voltage of sub-pixels with other pixel features is calculated according to the correction coefficient and pixel voltage of each monochrome sub-pixel in the target display panel. In this way, the pixel grayscale and pixel voltage of all sub-pixel arrays of the target display panel constitute the aforementioned pixel voltage lookup table.

[0133] In this embodiment, by obtaining the correction coefficient, the pixel voltage of sub-pixels with only one type of pixel characteristic of the target display panel can be obtained, and the pixel voltage of sub-pixels with other pixel characteristics can be obtained. Finally, a pixel voltage lookup table is obtained, thereby improving the color separation effect of the display panel.

[0134] In yet another example, the pixel voltage lookup table can be determined based on the type of pixel characteristic, see [link to relevant documentation]. Figure 8 This includes steps 81 to 83.

[0135] In step 81, when the number of pixel characteristics of each monochrome sub-pixel array in the target array is not a multiple, all sub-pixels are lit up at the same time, and the lit sub-pixels are adjusted according to the preset Gamma adjustment method to adjust the Gamma parameters and color coordinates of the white image, so as to obtain the pixel grayscale and pixel voltage of each sub-pixel under each monochrome sub-image corresponding to the white image.

[0136] In step 82, the pixel characteristics of all sub-pixels of each monochrome sub-pixel array in the target array are adjusted to the same brightness and the pixel voltage is corrected by Demura to obtain the pixel grayscale and pixel voltage of each sub-pixel.

[0137] In step 81, the pixel grayscale and pixel voltage of each sub-pixel under each color sub-image were obtained. In this step, Demura correction is performed on all pixel characteristics of each monochrome sub-pixel array. By correcting each monochrome sub-pixel one by one, the pixel characteristics of all pixel characteristics of each monochrome sub-pixel are adjusted to the same brightness. Then, Demura correction is performed on the pixel voltage of each pixel characteristic to obtain the pixel grayscale and pixel voltage of each sub-pixel. The Demura correction can be selected according to the specific scene and is not limited here.

[0138] In step 83, the pixel grayscale and pixel voltage of all sub-pixels in the display panel are determined to form the pixel voltage lookup table.

[0139] In this step, the pixel voltage of the sub-pixel with each pixel characteristic obtained in step 81 can be updated to the pixel voltage obtained in step 82. After obtaining the pixel voltage of all sub-pixels at different pixel gray levels, the pixel gray levels and pixel voltages of all sub-pixels in the display panel constitute the pixel voltage lookup table.

[0140] In this embodiment, by adding Demua correction to the pixel voltage of each monochrome sub-pixel, a pixel voltage lookup table can be obtained, thereby improving the color separation effect of the display panel.
