Description
Technical Field
The invention belongs to the technical field of display, and particularly relates to a compensation method and a display method of a display panel.
Background
With the development of display technology, an OLED (organic light-Emitting Diode) display device has become a new favorite of the current flat panel display device, and has many advantages of self-luminescence, fast response speed, wide viewing angle, and the like, so that the OLED display device is widely applied. The brightness Uniformity is an important factor influencing the display effect of the display screen, and at present, Long Range Uniformity (LRU) of the brightness of the display screen is introduced by display screen demand manufacturers to evaluate the performance of the display screen.
When the OLED display panel is lit, a voltage drop (IR-drop) exists between the input near end and the far end of the driving signal (ELVDD), which causes a decrease in luminance, and causes an uneven display of the overall luminance of the display panel, resulting in a poor long-range uniformity of the display panel, and the display defect is more serious especially for large-size and high-resolution products and when a highlight picture is displayed.
In the prior art, the phenomenon of poor long-range uniformity can be improved to a certain extent by an optical compensation (Demura) mode. The brightness distribution of the display panel cannot be faithfully reflected due to the dark angle (vignetting) or other factors when the camera takes a picture. When the existing compensation formula is used for calculating the Demura compensation data, errors occur in the compensation data, and the compensation effect on the long-range poor uniformity is not ideal.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
in the existing display device, the cross-sectional area of the power supply wiring inside the display panel is usually relatively small, so that a certain impedance is inevitably generated. When the display panel is lighted, the driving signal will have a voltage drop from the input near end to the input far end, so that the brightness of the input far end is reduced. Especially, when displaying a high gray scale image, the voltage drop variation amplitude caused by the power line impedance is relatively large due to the large current of the driving signal, and the brightness of the whole display panel is more non-uniform, so that the long-range uniformity of the display panel is worse. Similarly, for products with large size and high resolution, the bad phenomenon of the display image is also serious because the power supply has longer wiring length and larger total impedance.
In the case that the impedance of the power supply line cannot be eliminated, the phenomenon of poor long-range uniformity is improved to some extent by performing optical compensation (Demura) on the display of the display panel in the prior art. Specifically, the optical compensation process mainly includes display panel luminance distribution acquisition (preprocessing) and compensation data calculation (postprocessing). Wherein the data compensation algorithm comprises a first order compensation function or a second order compensation function. In the pre-processing process, the brightness distribution of the display panel can be acquired by photographing with a camera and the like. However, in practical situations, the brightness distribution of the display panel cannot be faithfully reflected due to the dark angle (vignetting) or other factors when the camera takes a picture. Therefore, in the subsequent data processing process, when the Demura compensation data is directly calculated according to the acquired brightness distribution data, errors occur in the compensation data, and the compensation effect on the long-range poor uniformity is not ideal.
In view of the above, the present embodiment provides a compensation method for a display panel, which can be used to compensate for the long-range uniformity of the display panel. In addition, the compensation method provided by the embodiment is particularly suitable for the OLED display panel, and can obviously solve the problem of poor long-range uniformity of the OLED display panel during display.
In the compensation method provided by this embodiment, based on the Demura algorithm in the prior art, the display of the display panel is compensated after the Demura algorithm is improved. Specifically, as shown in fig. 2, the compensation method provided in this embodiment may include the following steps:
and S11, acquiring compensation parameters in the initial optical compensation function corresponding to each pixel unit of the display panel.
The initial optical compensation function refers to a compensation function used for compensating each pixel unit of the display panel in the prior art. It is understood that the optical compensation function should be pre-stored in a binary document (bin document) and directly obtained.
Specifically, the optical compensation function may preferably include: y ═ gain x + offset (linear equation), or, y ═ beta ^ x ^2+ gain x + offset (quadratic equation). Wherein y is the gray scale after optical compensation; x is gray scale before optical compensation; gain is a primary compensation parameter; beta is a secondary compensation parameter; offset is a compensation constant.
That is, in the present embodiment, it is preferable to optically compensate each pixel unit of the display panel by the above-described linear equation or quadratic equation. In this step, the compensation parameter may include the primary compensation parameter and/or the secondary compensation parameter. Specifically, the primary compensation parameter and/or the secondary compensation parameter may be determined by calculating according to the compensation formula, the gray scale of each pixel unit before optical compensation and the gray scale obtained after optical compensation of the desired pixel unit.
It should be noted that, as shown in fig. 1, due to the influence of external environmental factors such as dark corners existing in the photographing process of the camera, the poor long-range uniformity of the display panel cannot be effectively improved after the display panel is directly compensated based on the original optical compensation function, and therefore, the optical compensation equation needs to be further adjusted through the subsequent steps.
And S12, adjusting the coefficient of the compensation parameter of the partial pixel unit according to the position information of the pixel unit in the display panel and a preset algorithm.
As can be seen from the above description, the effect of directly compensating the display panel based on the original optical compensation function is not good enough, so the optical compensation function is improved by adjusting the coefficient of the compensation parameter in this step. The dark angle of the camera is related to the position, and when the brightness distribution of the display panel is obtained, the brightness obtaining errors of different areas are affected by the dark angle differently. Therefore, in this embodiment, the coefficients of the compensation parameters of the partial pixel units are adjusted according to the position information of the pixel units in the display panel and a preset algorithm.
In this embodiment, the compensation parameter including the primary compensation parameter is taken as an example for explanation. Specifically, step S12 may include:
and S121, sequentially reducing the coefficient of the primary compensation parameter along the direction far away from the central area by taking the pixel unit positioned in the central area of the display panel as a reference according to the arrangement position of the pixel unit.
Through data acquisition of optical compensation and shooting influence factor analysis of a camera, multiple times of experimental data show that the coefficients of primary compensation parameters (namely Gain parameters) are properly and sequentially reduced along the direction far away from the central area by taking the pixel unit positioned in the central area of the display panel as a reference, and as shown in fig. 3, the long-range uniformity of the display panel during display can be obviously improved.
Further, as shown in fig. 4, when only the coefficient of the Gain parameter is changed, and the modification ratio range of the coefficient of the Gain parameter is (0, 0.06), the long-range uniformity is better than that of the prior art without modification. Therefore, the coefficient modification ratio range of the primary compensation parameter is preferably (0, 0.06). Further, when the modification ratio of the Gain parametric coefficient is 0.04 (4%), the long-range uniformity of the display panel can be relatively improved by 2% at most (as shown in fig. 4, 94% is improved to 96%).
It should be noted that the modification ratio range of the Gain parameter coefficient refers to a ratio of a coefficient of the adjusted optical compensation parameter corresponding to the edge-most pixel unit of the display panel to a coefficient difference of the optical compensation parameter corresponding to the pixel unit in the central area of the display panel to a coefficient of the optical compensation parameter corresponding to the pixel unit in the central area (i.e. of the edge pixel unit), for example, when the modification ratio is 0.06, the coefficient of the optical compensation parameter corresponding to the edge-most pixel unit of the display panel is adjusted by 6%, and in this embodiment, the coefficient is specifically decreased by 6%, at this time, the coefficient of the optical compensation parameter corresponding to the edge-most pixel unit of the display panel is 0.94, and the coefficient of the optical compensation parameter corresponding to the pixel unit in the central area of the display panel is 1.
Further preferably, when modifying the coefficient of the optical compensation parameter corresponding to each pixel cell of the display panel, as shown in fig. 5, the decrease width of the coefficient of the primary compensation parameter is preferably gradually increased in a direction away from the central region. That is to say, in the direction away from the central region, the coefficient of the optical compensation parameter corresponding to the pixel unit is gradually increased and decreased, so that the influence of factors such as the camera photographing dark angle on the display panel display is better corrected.
And S13, determining the adjusted optical compensation function corresponding to each pixel unit according to the adjusted compensation parameter coefficient, so as to compensate the long-range uniformity of the display panel according to the adjusted optical compensation function.
In this step, the display panel is controlled to display based on the optical compensation function after the compensation parameter coefficient is modified, so that the long-range uniformity of the display panel is improved while the optical compensation of the display panel is realized. The display panel is controlled to display based on the optical compensation function, which is a mature technical means in the field, and reference may be made to related technical data, which is not described in detail in this embodiment.
Example 2:
the present embodiment provides a compensation method for a display panel, which can be used to compensate the long-range uniformity of the display panel. The compensation method provided by this embodiment is similar to the compensation method provided by embodiment 1, and the long-range uniformity of the display panel is improved by adjusting the coefficient of the compensation parameter in the optical compensation function.
Similar to embodiment 1, the compensation method provided in this embodiment may also include the following steps:
and S21, acquiring compensation parameters in the initial optical compensation function corresponding to each pixel unit of the display panel.
And S22, adjusting the coefficient of the compensation parameter of the partial pixel unit according to the position information of the pixel unit in the display panel and a preset algorithm.
And S23, determining the adjusted optical compensation function corresponding to each pixel unit according to the adjusted compensation parameter coefficient, so as to compensate the long-range uniformity of the display panel according to the adjusted optical compensation function.
Step S21 and step S23 can refer to step S11 and step S13 in embodiment 1, respectively, which are not repeated in this embodiment.
Step S22 is similar to step S21 in embodiment 1, but particularly, in this embodiment, the compensation parameter is a quadratic compensation parameter. Specifically, step S22 may include:
and S221, sequentially reducing coefficients of the secondary compensation parameters along a direction far away from the central area by taking the pixel unit positioned in the central area of the display panel as a reference according to the arrangement position of the pixel unit.
Through data acquisition of optical compensation and shooting influence factor analysis of a camera, multiple times of experimental data show that the coefficients of secondary compensation parameters (namely Beta parameters) are properly and sequentially reduced along the direction far away from the central area by taking a pixel unit positioned in the central area of the display panel as a reference, the long-range uniformity of the display panel during display can be obviously improved, and the long-range uniformity is increased along with the increase of the modification range of the Beta coefficients.
Further, many experimental data show that, as shown in fig. 6, when only the coefficient of the Beta parameter is changed, and the modification ratio range of the coefficient of the Beta parameter is (0, 1), the long-range uniformity is better than that of the prior art without modification, so the coefficient range of the primary compensation parameter is preferably (0, 1), and as shown in fig. 6, when the modification ratio of the coefficient of the Beta parameter is 1 (100%), the long-range uniformity of the display panel can be relatively improved by 3.5% at most (as shown in fig. 6, 93% is improved to 96.5%).
It should be noted that, similar to the modification ratio range of the Gain parametric coefficient in embodiment 1, in this embodiment, the modification ratio range of the Beta parametric coefficient refers to a ratio of the modified coefficient of the optical compensation parameter corresponding to the edge-most pixel unit of the display panel to the coefficient of the optical compensation parameter corresponding to the pixel unit in the central area of the display panel.
Further preferably, when modifying the coefficient of the optical compensation parameter corresponding to each pixel cell of the display panel, the decrease width of the coefficient of the secondary compensation parameter is preferably gradually increased in a direction away from the central region. That is to say, in the direction away from the central region, the coefficient of the optical compensation parameter corresponding to the pixel unit is gradually increased and decreased, so that the influence of factors such as the camera photographing dark angle on the display panel display is better corrected.
Example 3:
the present embodiment provides a compensation method for a display panel, which can be used to compensate the long-range uniformity of the display panel. The compensation method provided by this embodiment is similar to the compensation method provided by embodiment 1, and the long-range uniformity of the display panel is improved by adjusting the coefficient of the compensation parameter in the optical compensation function.
Similar to embodiment 1, the compensation method provided in this embodiment may also include the following steps:
and S31, acquiring compensation parameters in the initial optical compensation function corresponding to each pixel unit of the display panel.
And S32, adjusting the coefficient of the compensation parameter of the partial pixel unit according to the position information of the pixel unit in the display panel and a preset algorithm.
And S33, determining the adjusted optical compensation function corresponding to each pixel unit according to the adjusted compensation parameter coefficient, so as to compensate the long-range uniformity of the display panel according to the adjusted optical compensation function.
Step S31 and step S33 can refer to step S11 and step S13 in embodiment 1, respectively, which are not repeated in this embodiment.
Step S32 is similar to step S21 in embodiment 1, but particularly, in the present embodiment, the compensation parameters include primary compensation parameters and secondary compensation parameters. Specifically, step S32 may include:
and S321, sequentially reducing coefficients of the primary compensation parameter and the secondary compensation parameter along a direction far away from the central area by taking the pixel unit positioned in the central area of the display panel as a reference according to the arrangement position of the pixel unit.
Through data acquisition of optical compensation and shooting influence factor analysis of a camera, multiple times of experimental data show that the coefficients of a primary compensation parameter (namely Gain parameter) and a secondary compensation parameter (namely Beta parameter) are reduced simultaneously along the direction far away from a central area by taking a pixel unit positioned in the central area of a display panel as a reference, the long-range uniformity of the display panel during display can be obviously improved, and the long-range uniformity is increased along with the increase of the coefficient modification range of the Beta parameter.
Furthermore, multiple times of experimental data show that the long-range uniformity of the display panel can be improved by 3% -6% and can be improved by 5% on average by reasonably adjusting the modification ranges of the Gain parameter coefficient and the Beta parameter coefficient.
Example 4:

Because the display method provided by the embodiment comprises the compensation method provided by the embodiment, after compensation display is performed on the display panel, the problem that the display long-range uniformity of the existing display panel, particularly the OLED display panel, is poor can be effectively solved.
Preferably, the display method in this embodiment further includes the steps of performing initial display on the display panel, and performing luminance distribution acquisition on the initially displayed display panel, so as to facilitate implementation of subsequent display compensation. It is understood that the initial display and the brightness distribution acquisition of the display panel are all well-established technical means commonly used in the art, and reference may be made to the relevant data, which will not be described in detail herein in this embodiment.
