Description

Technical Field

[0001] The present invention relates to the field of display panels, and in particular to a sub-pixel data compensation method and a display panel. Background Art

[0002] The reason why OLED (Organic Light Emitting Diode) technology can be widely used is that it has many advantages compared with other technologies. Because of these advantages, more and more display manufacturers around the world have invested in OLED research and development, which has greatly promoted the industrialization process of OLED. The mainstream OLED display driver part (introduced in units of a sub-pixel) includes TFT (thin film transistor) that controls the light emission of OLED devices, TFT that controls the current flowing through OLED devices, TFT that controls the potential on the initialization storage capacitor, TFT that compensates the threshold voltage of the driving TFT, and TFT that controls the data voltage to charge the storage capacitor.

[0003] There are two common RGB (sub-pixel) arrangements in the public. One is that the three sub-pixels RGB of a pixel are arranged in a row, each controlled by a Scan line, and the storage capacitors in the three sub-pixels RGB are charged and discharged at the same time. The other is that the three sub-pixels RGB of a pixel are arranged in two rows, and according to the algorithm, the time jitter is added together to realize pixel display, but among the three sub-pixels RGB, only RG or BG of the storage capacitors are charged and discharged at the same time.

[0004] Since the light emission of sub-pixel R (red) is greatly affected by G (green) and B (blue), once R is affected, the light emission efficiency of R is reduced, resulting in changes in the brightness of pure color R at low grayscale. This phenomenon is called Gray crush. Summary of the invention

[0013] Among them, the step of obtaining the first influence value of the first sub-pixel affected by the second sub-pixel, and the second influence value of the first sub-pixel affected by the third sub-pixel, also includes: establishing a first table based on the influence value of the second sub-pixel displaying the second grayscale when the first sub-pixel displays the first grayscale; wherein the first grayscale includes 0-255 grayscales; establishing a second table based on the influence value of the third sub-pixel displaying the third grayscale when the first sub-pixel displays the first grayscale; wherein the second grayscale includes 0-255 grayscales; obtaining the first display grayscale of the first sub-pixel, the second display grayscale of the second sub-pixel, and the third display grayscale of the third sub-pixel of the image to be displayed; wherein the first display grayscale, the second display grayscale and the third display grayscale are any one of 0-255 grayscales; according to the first display grayscale and the second display grayscale, obtaining the first influence value from the first table; and according to the first display grayscale and the third display grayscale, obtaining the second influence value from the second table.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said", and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless otherwise clearly indicated above, and "multiple" generally includes at least two, but does not exclude the inclusion of at least one.

[0028] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0029] It should be understood that the terms "include", "comprises" or any other variations used herein are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0030] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The presence of the phrase at each location in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] It should be noted that the root causes of grayscale squeezing include: parasitic capacitance between adjacent data lines, which causes data voltage fluctuations. For details, please refer to Figure 1 , Figure 1 is a voltage variation diagram between two adjacent data lines in this application, such as Figure 1 As shown in FIG. 1 , when the data voltage on S1 (data line) increases or decreases, it will affect S2 (data line). Figure 1 As shown in b, S1 is the actual change waveform, S2' is the ideal output waveform, and S2 is the actual output waveform. The main reason for the fluctuation of the actual output waveform of S2 is that the voltage difference across the parasitic capacitor Cpp will not change instantaneously, so the rise of S1 will cause S2 to rise, and the fall of S1 will cause S2 to fall. In a row, the adjacent data lines S1 and S2 will charge the storage capacitor Cst of the corresponding sub-pixel. Once the fluctuation caused by S1 to S2 is mistakenly given to the storage capacitor Cst of the sub-pixel controlled by S2, it will cause the sub-pixel controlled by S2 to display abnormally.

[0033] For the RGB sub-pixels in OLED, the threshold voltage of the R material is the smallest (determined by the material). Therefore, once the data line that provides data to the R sub-pixel is affected by other data lines, the brightness change of R is more obvious, and the improvement of the corresponding product will have a qualitative change.

[0034] This application provides a sub-pixel data compensation method. Figure 2 , Figure 2 FIG. 1 is a flow chart of an implementation method of a sub-pixel data compensation method of the present application. Figure 2 As shown, the sub-pixel data compensation method includes:

[0035] Step S11: obtaining a first influence value of a first sub-pixel on a first side influenced by a second sub-pixel adjacent to the first sub-pixel, and a second influence value of a first sub-pixel on a third sub-pixel adjacent to the first sub-pixel on the other side thereof.

[0036] Before the step, it also includes: judging whether the second sub-pixel and the third sub-pixel are located on opposite sides of the first sub-pixel, if so, executing step S11, and obtaining the first influence value and the second influence value, if not, obtaining the influence value of the second sub-pixel or the third sub-pixel that is most adjacent to the first sub-pixel. Specifically, if the first sub-pixel is located at the outermost edge, that is, the data line of the first sub-pixel is the first data line or the last data line, then obtaining the data line of one of the second sub-pixel or the third sub-pixel adjacent thereto, and the influence value of the data line on the first sub-pixel. If the data line of the first sub-pixel is located between the data line of the second sub-pixel and the data line of the third sub-pixel, then obtaining the first influence value and the second influence value.

[0037] For more details, please refer to Figure 3 , Figure 3 This is a structural diagram of an embodiment of the pixel arrangement method of the present application. Figure 3 As shown, the first data line S1 corresponding to the first sub-pixel 1 is located between the second data line S2 corresponding to the second sub-pixel 2 and the third data line S3 corresponding to the third sub-pixel 3. The first data line S1 of the first sub-pixel 1 is affected by the coupling effect of S2 and S3.

[0038] The influence value of the second sub-pixel on the grayscale displayed by the first sub-pixel is a first influence value, and the influence value of the third sub-pixel on the grayscale displayed by the first sub-pixel is a second influence value.

[0039] In a specific embodiment, the first sub-pixel is a red sub-pixel, the second sub-pixel is one of a blue or green sub-pixel, and the third sub-pixel is the other of a blue or green sub-pixel. In this embodiment, data compensation for the red sub-pixel is achieved because the red sub-pixel is more susceptible to grayscale squeezing than the blue and green sub-pixels. In other embodiments, the first sub-pixel, the second sub-pixel, and the third sub-pixel can also be one of R, G, and B, respectively. Specifically, the first sub-pixel can also be a blue sub-pixel, and the second and third sub-pixels can be the other two types, then data compensation for the blue sub-pixel is achieved; if the first sub-pixel is a green sub-pixel, and the second and third sub-pixels can be the other two types, then data compensation for the green sub-pixel is achieved, which is not limited here.

[0040] Step S12: Determine whether the first influence value and the second influence value are in the same direction.

[0041] If yes, execute step S13, if no, execute step S14.

[0042] The first influence value and the second influence value being in the same direction means that the first influence value and the second influence value are in the same direction, that is, the first influence value and the second influence value are both positive values ​​or both negative values.

[0043] It should be noted that the first impact value refers to the impact value of the voltage of the data line of the second sub-pixel on the voltage of the data line of the first sub-pixel, that is, the voltage impact value. Similarly, the second impact value is also a voltage impact value.

[0044] Wherein, a positive value of the first influence value indicates that the data line of the second sub-pixel has a pull-up effect on the voltage of the data line of the first sub-pixel, and a negative value of the first influence value indicates that the data line of the second sub-pixel has a pull-down effect on the voltage of the data line of the first sub-pixel. Similarly, the positive or negative value of the second influence value also indicates a pull-up effect and a pull-down effect.

[0045] The same direction means that the data line of the second sub-pixel and the data line of the third sub-pixel both have a pull-up effect or a pull-down effect on the data line of the first sub-pixel.

[0046] Step S13: determining a data compensation value of the first sub-pixel according to one of the first influence value and the second influence value.

[0047] The data compensation value of the first sub-pixel refers to a compensation value for voltage compensation of the data line of the first sub-pixel.

[0048] In a specific embodiment, this step also includes: comparing whether the absolute value of the first influence value is greater than the absolute value of the second influence value; if so, determining the data compensation value of the first sub-pixel according to the first influence value; if not, determining the data compensation value of the first sub-pixel according to the second influence value. Specifically, it includes: if both the first influence value and the second influence value are positive values, further determining whether the first influence value is greater than the second influence value, if so, determining the data compensation value of the first sub-pixel according to the first influence value, if not, determining the data compensation value of the first sub-pixel according to the second influence value. When both the first influence value and the second influence value are negative values, further determining whether the first influence value is greater than the second influence value. If not, determining the data compensation value of the first sub-pixel according to the first influence value, if so, determining the data compensation value of the first sub-pixel according to the second influence value.

[0049] In the above manner, the second sub-pixel and the third sub-pixel are compared to see which has a greater impact on the first sub-pixel. Specifically, the voltage difference between the data line of the first sub-pixel and the data line of the second sub-pixel and the data line of the third sub-pixel can be compared. The greater the voltage difference, the greater the impact.

[0050] For a specific R sub-pixel, there will be two adjacent data lines. The left data line will affect R, and the right data line S2 will also have an impact. But overall, it depends on which one has a larger voltage difference with S1. In this way, the impact will be greater, and the phenomenon will follow.

[0051] Step S14: determining a data compensation value of the first sub-pixel according to a superposition value of the first influence value and the second influence value.

[0052] This step includes two situations: the first impact value is a positive value and the second impact value is a negative value, and the first impact value is a negative value and the second impact value is a positive value.

[0053] The superposition value refers to the superposition value of the influence of the second sub-pixel and the third sub-pixel on the first sub-pixel, which is calculated based on the sum of the first influence value and the second influence value. The calculation includes the positive and negative of the first influence value and the second influence value. Specifically, if the first influence value is V1 and the second influence value is -V2, then the superposition value = V1 + (-V2).

[0054] In a specific implementation, the superimposed value may be directly used as the data compensation value of the first sub-pixel. In other implementations, the superimposed value may be multiplied by the loss coefficient to obtain the data compensation value of the first sub-pixel, which is not limited here.

[0055] After steps S13 and S14, the method also includes: obtaining the initial voltage of the data line of the first sub-pixel; using the sum of the data compensation value of the first sub-pixel and the initial voltage value of the data line in the first sub-pixel to determine the actual data voltage output to the first sub-pixel, so as to achieve the purpose of compensating the display grayscale of the first sub-pixel.

[0056] In a specific application scenario, if the first impact value is v1, the second impact value is v2, and v1>v2, then the data compensation value of the first sub-pixel is v1, if not, then v2; if the first impact value is -v1, the second impact value is -v2, and -v1<-v2, then the data compensation value of the first sub-pixel is -v1, if not, then -v2; if the first impact value is v1, the second impact value is -v2, then the data compensation value of the first sub-pixel is v1-v2. In other embodiments, the data compensation value may also be multiplied by the loss coefficient to obtain the actual data compensation value, which is not limited here.

[0057] In a specific implementation, step S11 further includes steps S111-S112, for details, please refer to Figure 4 , Figure 4 for Figure 1 Step S11 is a flowchart of the first specific implementation method.

[0058] like Figure 4 As shown, including:

[0059] Step S111: obtaining a first display grayscale of a first sub-pixel, a second display grayscale of a second sub-pixel, and a third display grayscale of a third sub-pixel in a picture to be displayed.

[0060] Step S112: obtaining a first influence value of the first sub-pixel displaying the first display grayscale being affected by the second sub-pixel displaying the second display grayscale, and obtaining a second influence value of the first sub-pixel displaying the first display grayscale being affected by the third sub-pixel displaying the third display grayscale.

[0061] In this embodiment, step S112 includes: inputting a first data voltage corresponding to a first display grayscale to the data line of the first sub-pixel through a driving circuit (driving IC), inputting a second data voltage corresponding to a second display grayscale to the data line of the second sub-pixel, and obtaining a change value of the first data voltage on the data line of the first sub-pixel through the driving circuit to obtain the first influence value; wherein, when the first influence value is obtained, the third sub-pixel does not display. Inputting a first data voltage corresponding to a first display grayscale to the data line of the first sub-pixel, and inputting a third data voltage corresponding to a third display grayscale to the data line of the third sub-pixel, obtaining a change value of the first data voltage on the data line of the first sub-pixel through a driving IC (integrated circuit) to obtain the second influence value, wherein, when the second influence value is obtained, the second sub-pixel does not display.

[0062] In this embodiment, the method further includes: obtaining an initial data voltage input to the data line of the first sub-pixel when the first sub-pixel displays the first display grayscale; obtaining an actual data voltage on the data line of the first sub-pixel when the first sub-pixel displays the first display grayscale, and calculating the impact value on the data line of the first sub-pixel by subtracting the initial data voltage from the actual data voltage. In this embodiment, the impact value is measured by measuring the voltage on the data line. In other methods, the impact value can also be obtained by measuring the brightness of the displayed grayscale.

[0063] In this embodiment, after step S14, the method further includes: driving the first sub-pixel based on the data compensation value, so that the first sub-pixel displays a first display grayscale.

[0064] The first display grayscale, the second display grayscale and the third display grayscale all include 0-255 grayscales.

[0065] In another specific implementation, step S11 also includes establishing a table. Figure 5 , Figure 5 for Figure 1 Schematic diagram of the second specific implementation of step S11 in FIG. Figure 5 As shown, step S11 also includes:

[0066] Step S121 : establishing a first table according to the influence of the first sub-pixel displaying the first grayscale on the second sub-pixel displaying the second grayscale.

[0067] The first grayscale is 0-255 grayscale, and the second grayscale is 0-255 grayscale. Specifically, the method includes obtaining the corresponding influence values ​​when the first sub-pixel displays 0 grayscale and the second sub-pixel displays 0-255 grayscale; obtaining the corresponding influence values ​​when the first sub-pixel displays 1 grayscale and the second sub-pixel displays 0-255 grayscale; and so on, obtaining the influence values ​​in the first table.

[0068] Among them, the first table is a two-dimensional table, and the first table is shown in the following table:

[0069]

[0070] The first sub-pixel is a red sub-pixel R, and the second sub-pixel is a green sub-pixel G. This is not limited here.

[0071] Step S122 : establishing a second table according to the influence of the third sub-pixel displaying the third grayscale on the first sub-pixel displaying the first grayscale.

[0072] The first grayscale includes grayscales of 0-255, and the third grayscale includes grayscales of 0-255.

[0073] Among them, the second table is also a two-dimensional table. Please refer to the above table for details and will not be described here.

[0074] Step S123: obtaining a first display grayscale of a first sub-pixel, a second display grayscale of a second sub-pixel, and a third display grayscale of a third sub-pixel of a picture to be displayed.

[0075] The first display grayscale, the second display grayscale and the third display grayscale are all specific display grayscales in the grayscale range of 0-255. In other words, the first grayscale includes multiple first display grayscales, the second grayscale includes multiple second display grayscales, and the third grayscale includes multiple third display grayscales. The multiple is 256.

[0076] Step S124: acquiring a first influence value from a first table according to the first display grayscale and the second display grayscale; and acquiring a second influence value from a second table according to the first display grayscale and the third display grayscale.

[0077] Compared with the first embodiment, the present embodiment can directly call the first influence value and the second influence value from the established first table and the second table, thereby eliminating the step of repeated measurement.

[0078] In another specific embodiment, the compensation value can be directly filled in the first table and the second table. Specifically, if the influence value of the second sub-pixel on the first sub-pixel is a, -a can be filled in the first table, and in the calling process, -a can be directly added to obtain the actual output voltage after compensation.

[0079] The beneficial effect of this embodiment is: obtaining a first influence value of the first sub-pixel affected by the second sub-pixel, and a second influence value of the first sub-pixel affected by the third sub-pixel, and determining a data compensation value for the first sub-pixel according to the influence value, thereby compensating the data voltage of the first sub-pixel so that the display grayscale of the first sub-pixel can reach a preset display grayscale, thereby preventing the display grayscale of the first sub-pixel from being squeezed by the grayscales of other sub-pixels, resulting in poor picture display.

[0080] The present application also provides a display panel, the display panel includes a plurality of pixel units arranged in an array, each pixel unit includes at least a first sub-pixel, a second sub-pixel and a third sub-pixel, wherein the first sub-pixel is arranged in parallel and adjacent to at least one of the second sub-pixel and the third sub-pixel. Figure 6 and Figure 7 , Figure 6 This is a schematic structural diagram of the first embodiment of the display panel of the present application. Figure 7 Schematic diagram of the structure of the second embodiment of the display panel of the present application. Figure 6 As shown, the first sub-pixel 1 and the second sub-pixel 2 are arranged in parallel, that is, in the same row, and the third sub-pixel 3 is located in another row, which is not limited here. Figure 7 As shown, the first sub-pixel 1, the second sub-pixel 2, and the third sub-pixel 3 are all arranged in parallel, and the first sub-pixel 1 is located between the second sub-pixel 2 and the third sub-pixel 3. The first sub-pixel 1, the second sub-pixel 2, and the third sub-pixel 3 are not limited to the same pixel unit 10. For example, the first sub-pixel 1 may be a sub-pixel in the first pixel unit, and the second sub-pixel 2 adjacent thereto may be a sub-pixel derived from the second pixel unit.

[0081] The first sub-pixel, the second sub-pixel and the third sub-pixel are one of R, G and B. Of course, each pixel unit may also include a white sub-pixel, which is not limited here.
