Description
Technical Field
The present disclosure relates to crosstalk compensation, and more particularly to a crosstalk compensation method and device for a display panel, and a storage medium.
Background
The existing display panel has the advantages of light weight, small volume, low power consumption, low battery and the like, and is widely used for various communication and consumer electronic products such as televisions, notebook computers, mobile phones, personal digital assistants and the like. In order to increase the aperture ratio of the pixels on the display panel to obtain higher transmittance or lower power consumption, the pitch between adjacent sub-pixel electrodes is generally reduced, and even the sub-pixel electrodes overlap the data lines of the adjacent sub-pixels. However, this causes increased capacitive coupling and thus cross-talk.
Crosstalk is a change in the state of the display pixels in the display panel due to other display pixels or operating electrodes, which affects the original display state of the pixels. The phenomenon of crosstalk is particularly pronounced in high pixel density OLED displays. The causes can be classified into two large categories, electrical crosstalk and optical crosstalk. Electrical crosstalk is caused by lateral currents through the common layer; and optical crosstalk is caused by light leakage from other pixels. Crosstalk of pixels can reduce contrast and hinder the final display gamut and the contour edge definition of the picture. For example, when an image is displayed, under the condition that the gray scale in the image changes greatly, the ELVDD (OLED device power supply voltage-anode) or ELVSS (OLED device common ground voltage-cathode), the instantaneous voltage change occurs at the junction between the light load and the heavy load where the current flows. The change of the voltage and current can cause crosstalk interference on the display image of the panel.
The existing effects of eliminating or reducing crosstalk interference are generally: for electrical crosstalk, different pixel circuit designs are utilized to achieve current or voltage compensation, so that the stability of a display image in the display panel is ensured; the reduction of optical crosstalk requires improvement of the process of manufacturing the display panel. Such as the thickness of the light emitting layer, the spacing between layers, the angle of the structure, the refractive index of the encapsulation material, etc., in the display panel. As can be seen, the conventional method for eliminating crosstalk requires changing the design of the display panel or the display driving circuit of the display panel, which is complex and costly.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings, and the described embodiments should not be construed as limiting the present application, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of the present application.
In the following description, reference is made to "one embodiment" or "one embodiment" and the like, which describe a subset of all possible embodiments, but it is to be understood that "one embodiment" or "one embodiment" may be the same subset or a different subset of all possible embodiments and may be combined with each other without conflict. In the following description, the term plurality refers to at least two.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
In the conventional display panel, voltages corresponding to different gray scales are applied to adjacent sub-pixels, respectively, in many cases when displaying an image. When voltages corresponding to different gray scales are respectively applied to adjacent sub-pixels, crosstalk is easily generated because a spike generated with voltage switching of a scan line affects an effective value of a voltage applied to the pixel. As shown in fig. 1, the right image is an image without crosstalk, wherein the middle black pattern is a display pattern, gray is a background, the left image is an image with crosstalk, and the upper and lower edges of the black pattern have light gray lines, which is a phenomenon of crosstalk. When the black pattern is scanned from the gray background color to the black pattern in the image, or the black pattern is scanned to the gray background color, the gray scale can be changed greatly, and the instantaneous voltage change can occur at the junction of the light load and the heavy load of the current. The change of the voltage and current can cause crosstalk interference on the display image of the panel. The existing effects of eliminating or reducing crosstalk interference are generally: for electrical crosstalk, different pixel circuit designs are utilized to achieve current or voltage compensation, so that the stability of a display image in the display panel is ensured; the reduction of optical crosstalk requires improvement of the process of manufacturing the display panel. Such as the thickness of the light emitting layer, the spacing between layers, the angle of the structure, the refractive index of the encapsulation material, etc., in the display panel. As can be seen, the conventional method for eliminating crosstalk requires changing the design of the display panel or the display driving circuit of the display panel, which is complex and costly. Therefore, the embodiment of the application provides a crosstalk compensation method for a display panel, which can be used for easily and conveniently compensating crosstalk without changing the design of the display panel or the display driving circuit of the display panel, and has the following specific steps as shown in fig. 2:
201. and acquiring a crosstalk interference image corresponding to the display panel.
In this embodiment of the present application, the crosstalk compensation device of the display panel may obtain a crosstalk interference image corresponding to the display panel, where the display panel may be a display screen or an OLED panel, and the disclosure is not limited thereto. The crosstalk interference image corresponding to the display panel can be obtained by photographing the display panel with the crosstalk interference phenomenon or performing screenshot. It is understood that a plurality of crosstalk images corresponding to the display panel can be obtained.
202. And obtaining first compensation values corresponding to the patterns with different sizes according to the sizes of the patterns in the crosstalk interference image and a preset gray level compensation table.
After the crosstalk interference image corresponding to the display panel is obtained, the first compensation values corresponding to the patterns with different sizes can be obtained according to the sizes of the patterns in the crosstalk interference image and a preset gray level compensation table. The size of the pattern in the crosstalk image refers to the size of the display pattern in the crosstalk image. It can be understood that when different crosstalk images are displayed on the same display panel, as the pattern size (pattern width) becomes larger, the circuit load is increased, the crosstalk phenomenon becomes more obvious, the required compensation value is larger, and the required compensation value for different pattern sizes is measured by displaying different crosstalk images on the display panel according to the characteristic mechanical energy measurement of the display panel.
It will be appreciated that crosstalk occurs when the gray level of the display pattern changes significantly, resulting in an unexpected momentary voltage difference due to load changes, resulting in unexpected bright and dark lines on the panel display. According to the gray level difference degree in different crosstalk interference images and different circuit loads caused by different pattern sizes, image analysis can be performed to construct a set of table look-up compensation values. Specifically, a first gray level difference corresponding to adjacent pixels in the crosstalk interference area when the display panel displays patterns with different sizes can be obtained; the crosstalk interference area is generally an area where crosstalk interference is generated due to load variation when color variation exists in the crosstalk interference image. It will be appreciated that the non-pattern size in the crosstalk image requires different circuit loads when displayed, which may result in different gray scale differences, i.e. crosstalk phenomena. The first compensation value corresponding to the first gray level difference is determined in the preset gray level compensation table, as shown in fig. 3, the gray level is generally 0 to 255, and the corresponding first compensation value can be found in the preset gray level compensation table by measuring the gray level difference signal of the first gray level difference of the adjacent pixels in the crosstalk interference area, and the first compensation value can include a red sub-pixel compensation value, a green sub-pixel compensation value and a blue sub-pixel compensation value.
The first compensation value which is needed to be applied when the current display panel displays different pattern sizes can be obtained, and it can be understood that the first compensation value comprises a plurality of compensation values, and each compensation value corresponds to the gray level difference of the adjacent pixels in the crosstalk interference area. The display panels of the same type can use the same group of table lookup compensation values, and when the display panels of different types are replaced or the display panels are made differently, the first compensation value needs to be measured and fine-tuned again. The first compensation values can be made into a group of table lookup values, the crosstalk interference images with different gray level differences and patterns with different sizes can be measured, and the compensation characteristics can be made into a group of table lookup values, so that table lookup compensation can be performed when crosstalk interference occurs.
203. And adjusting the weight of the first compensation value according to the display brightness of the display panel and the screen refreshing rate to obtain a second compensation value.
After the first compensation values corresponding to the patterns with different sizes are obtained, the weight of the first compensation values can be adjusted according to the display brightness of the display panel and the screen refresh rate to obtain the second compensation values. It can be understood that, in the same display panel and the same crosstalk image, setting different display brightness (backlight brightness) or different screen refresh rates of the display panel may cause different compensation values, and the weight adjustment is performed in the two aspects, so that the display panel can be more satisfied and the display panel is cut to different settings, and the display panel corresponds to a more appropriate compensation value.
Specifically, after the first compensation values corresponding to the patterns with different sizes are obtained, when the corresponding crosstalk interference images are compensated by using the first compensation values in the display panel, the display brightness and the screen refresh rate of the display panel are adjusted to adjust the weight of the first compensation values until the crosstalk interference does not exist in the display images of the display panel, and the second compensation value is obtained. The display brightness and the screen refresh rate of the display panel are adjusted by using the corresponding first compensation value under the preset gray level difference of the crosstalk interference area, and the gray level difference of the crosstalk interference area is fed back until the gray level difference is zero (i.e. no crosstalk interference exists in human eye observation), so as to obtain the second compensation value. In the embodiment of the application, the compensation value of crosstalk interference can be adjusted according to the display brightness and the screen refresh rate of the display panel, so that the accuracy of crosstalk compensation is improved.
204. And determining a target compensation value from the second compensation value according to the size of the target pattern in the target crosstalk interference image.
In this embodiment of the present application, after the weight of the first compensation value is adjusted to obtain the second compensation value, when the target crosstalk interference image appears on the display panel, the target compensation value may be determined from the second compensation value according to the size of the target pattern in the target crosstalk interference image. Specifically, a pattern size matching the size of the target pattern may be determined in the crosstalk image; and taking the second compensation value corresponding to the matched pattern size as a target compensation value. It can be understood that the second compensation values corresponding to the plurality of pattern sizes of the display panel can be obtained by the method, and the corresponding second compensation values can be obtained by matching the pattern sizes. The target compensation value is selected from the second compensation values corresponding to the pattern sizes, the target compensation value comprises a plurality of compensation values, and the crosstalk compensation device can use the target compensation value to compensate the target crosstalk interference image.
205. And compensating the target crosstalk interference image by using the target compensation value.
The crosstalk compensation apparatus compensates the target crosstalk image using the target compensation value. Specifically, in the crosstalk interference area of the target crosstalk interference image, determining a second gray level difference corresponding to two adjacent pixel scanning lines; it will be appreciated that the display panel typically scans laterally when displaying images, and that crosstalk interference is typically caused by the load differential between adjacent scan lines. And determining a compensation value corresponding to the second gray level difference in the target compensation values, and compensating the second gray level difference by using the corresponding compensation value. It can be understood that the crosstalk interference area corresponding to the target crosstalk interference image generally has a certain width, that is, the crosstalk interference area is an area scanned by a plurality of scan lines, that is, the crosstalk interference area has a plurality of second gray level differences; the target compensation value comprises a plurality of compensation values corresponding to the gray level differences, and the gray level differences are matched to determine the compensation value corresponding to the second gray level difference. The crosstalk compensation may be compensated using progressive compensation or dithering algorithms, and is not limited in particular herein.
The crosstalk interference area of the target crosstalk interference image may include: any one or more of an upper boundary interference region, a lower boundary interference region, and an intermediate interference region of a target pattern in a target crosstalk image. The compensation area of crosstalk interference can be divided into two parts, namely compensation of different loads at the pattern boundary and compensation of the middle area of the pattern. As shown in fig. 4, the upper boundary interference area line1 and the lower boundary interference area line2 of the target pattern extend up and down to control the compensation values respectively, so as to reversely describe the crosstalk phenomenon of the current to the display panel, thereby achieving the purpose of eliminating the crosstalk interference. Specifically, for the upper boundary interference area of the target pattern, mainly the interference area corresponding to gray to black is converted, and the compensation of the upper boundary interference area is forward compensation, namely, the target compensation value is increased on the scanning line; the lower boundary interference area is mainly the interference area corresponding to black to gray, and the compensation in the lower boundary interference area is reverse compensation, namely, the target compensation value is increased or decreased in the scan line. The crosstalk phenomenon may also exist in the middle interference Area of the target pattern, and the independent compensation value in the middle interference Area of the target pattern may be controlled to satisfy the crosstalk phenomenon of different display panels.
Further, after compensating the target crosstalk interference by using the target compensation value, the method further includes: if there is a non-eliminated area of the crosstalk interference in the target crosstalk interference image, the weight of the non-eliminated area corresponding to the target compensation value is adjusted until the non-eliminated area eliminates the crosstalk interference. It can be understood that after the gray level difference caused by the load change is compensated, crosstalk may still exist, and the weight of the compensation value corresponding to the gray level difference needs to be adjusted to eliminate the crosstalk.
As can be seen, the method of the embodiment of the present application includes: acquiring a crosstalk interference image corresponding to a display panel; obtaining first compensation values corresponding to patterns with different sizes according to the sizes of the patterns in the crosstalk interference image and a preset gray level compensation table; the weight of the first compensation value is adjusted according to the display brightness of the display panel and the screen refreshing rate, so that a second compensation value is obtained; when the target crosstalk interference image appears on the display panel, determining a target compensation value from the second compensation value according to the size of the target pattern in the target crosstalk interference image, and compensating the target crosstalk interference image by using the target compensation value; the target crosstalk interference images are compensated by the compensation values corresponding to the patterns with different sizes, the display panel design or the display driving circuit of the display panel is not required to be changed, and the method is simple and convenient and reduces the cost. In one embodiment, the crosstalk image is used to compensate the data corresponding to the crosstalk image in the opposite direction, so as to avoid modifying the design of the display panel or the display driving circuit of the panel. Or when the panel and hardware compensation is limited, the compensation is performed by the data, so as to adapt to different panel architecture designs, and the data corresponding to the crosstalk interference image is directly compensated reversely. The compensation value is flexibly adjusted, and various variable parameters such as gray level difference, pattern size, display brightness and screen refresh rate can be covered. The compensation range is also controlled and adjusted for each scan line around the crosstalk pattern to achieve the most flexible configuration.
