Pursuant to 35 U.S.C. § 119 and the Paris Convention, this application claims the benefit of Chinese Patent Application No. 202310824717.7, filed on Jul. 6, 2023, the content of which is incorporated herein by reference.
The present application relates to the field of display technology, and in particular, to a method and a device for a picture detection, a display panel and a computer-readable storage medium.
The statements provided herein are merely background information related to the present application, and do not necessarily constitute any prior arts. Thin film transistor liquid crystal display (TFT-LCD), compared with traditional cathode ray tube (CRT) displays, plasma displays, etc., has the advantages of low power consumption, environmental protection, and space saving. Currently, TFT-LCD is also developing towards higher resolution, higher display quality and larger size.
Each sub-pixel of TFT-LCD includes a liquid crystal capacitor and a storage capacitor. One end of the liquid crystal capacitor and storage capacitor is connected to the pixel electrode, and the other end is connected to the common electrode (VCOM). When TFT-LCD is driven, the common electrode is prone to be interfered by a data line, which results in voltage jitter, and then leads to an abnormal phenomenon such as crosstalk in the display screen. Usually, the picture detection function (PDF) is applied to solve this problem.
However, in related technologies, TFT-LCD cannot accurately exit the picture detection function after the picture detection function is enabled, which will cause a waste of resources.
The present application provides a method and a device for a picture detection, a display panel and a computer-readable storage medium, which can accurately exit the picture detection function and save resources. Technical schemes of the present application are as follows:
In accordance with a first aspect, a method for a picture detection is provided, and the method includes steps of: obtaining a grayscale value of each sub-pixel in each minimum detection unit respectively; exiting a picture detection function if at least one of x minimum detection units meets its corresponding first preset condition when the picture detection function for the preset detection area is in an enabled state. A first preset condition corresponding to a first minimum detection unit is that the grayscale value of at least one sub-pixel of a first type is smaller than or equal to a first value, or the grayscale value of at least one sub-pixel of a second type is greater than or equal to a second value. The first minimum detection unit is any one of the x minimum detection units, the sub-pixel of the first type refers to a sub-pixel in the first minimum detection unit whose grayscale value is greater than or equal to a third value when the picture detection function is enabled, and the sub-pixel of the second type refers to a sub-pixel in the first minimum detection unit whose grayscale value is smaller than or equal to a fourth value when the picture detection function is enabled. The first value is smaller than the third value, the second value is greater than the fourth value, the first value is greater than the second value, and the third value is greater than the fourth value.
In some possible implementations, the third value and the fourth value are respectively determined based on original grayscale values of all sub-pixels in the first minimum detection unit. The original grayscale values refer to grayscale values of the sub-pixels before the picture detection function is enabled.
In some possible implementations, the method also includes a step of maintaining the picture detection function at the enabled state if each of the x minimum detection units does not meet its corresponding first preset condition when the picture detection function is in the enabled state.
In some possible implementations, the method also includes a step of enabling the picture detection function if each of the x minimum detection units meets its corresponding second preset condition when the picture detection function is in a disabled state. A second preset condition corresponding to the first minimum detection unit includes that at least one sub-pixel of the first type and at least one sub-pixel of the second type are both presented in the first minimum detection unit.
In some possible implementations, the method also includes a step of maintaining the picture detection function at the disabled state if at least one of the x minimum detection units does not meet its corresponding second preset condition when the picture detection function is in the disabled state.
In some possible implementations, the second preset condition corresponding to the first minimum detection unit also includes that an area of the preset detection area exceeds a preset area threshold. In some possible implementations, the step of exiting the picture detection function includes a step of exiting the picture detection function after scanning a current frame of picture and before starting to scan a next frame of picture.
In the method for the picture detection provided by the embodiment of the present application, the grayscale values of all sub-pixels in the preset detection area are obtained respectively, and the picture detection function is exited if at least one of the minimum detection units meets its corresponding exit condition when the picture detection function is in the enabled state. By improving the conditions for exiting the picture detection function, this method closely combines the causes of crosstalk with the conditions for exiting the picture detection function, so that the conditions for exiting the picture detection function can cover situations of complete black and full brightness of the screen, as well as other situations where the polarity distribution is uniform but the picture detection function needs to be exited. In addition, for the pictures that will not cause crosstalk, the picture detection function is excluded (i.e. exited), thus the accuracy of the picture detection function is improved, and a waste of resources is avoided.
In a second aspect, a device for a picture detection is provided. The device for the picture detection includes an acquisition circuitry and a determination circuitry.
In a third aspect, a display panel is provided. The display panel includes a memory, a processor, and a computer program stored in the memory and executable by the processor. The computer program, when executed by the processor, enables the above method for the picture detection to be implemented.
In a fourth aspect, a computer-readable storage medium is provided. The computer-readable storage medium stores a computer program. The computer program, when executed by a processor, causes the above-mentioned method for the picture detection to be implemented.
It can be understood that, for beneficial effects of the above second aspect, third aspect, and fourth aspect, references may be made to the relevant descriptions in the above first aspect, which will not be described again here.

Before the detailed explanation of the embodiments of the present application, application scenarios of the embodiments of the present application are described herein.
The method for the picture detection provided by an embodiment of the present application is applied to a display panel and configured to perform picture detection on the display panel. Taking TFT-LCD as an example, a driving mode of the display panel may be a line-by-line scan driving. Particularly, as shown in
Taking any sub-pixel in the row G1-th as an example, a schematic diagram of the corresponding switch circuit is shown in
Based on the switch circuit shown in
However, VCOM is easily disturbed by data voltage, resulting in voltage jitter. This voltage jitter can cause abnormalities such as crosstalk in the picture. Specifically, as shown in
However, it is noted by the inventor based on research that, the display screen is completely black when the grayscale values of all sub-pixels are 0 in case that the picture detection function is enabled. At this time, no crosstalk abnormality will occur, and the picture detection function needs to be exited. However, in the related technology, after the picture detection function is enabled on the display panel, the conditions for exiting the picture detection function cannot include the situation that the display screen is completely black. At this time, the picture detection function cannot be accurately exited, which will cause a waste of resources.
To this end, embodiments of the present application provide a method for a picture detection. By changing the conditions for exiting the picture detection function, to enable the exit conditions of the picture detection function to cover situations such as a completely black screen, the picture detection function can be accurately exited, thereby saving resources.
To facilitate understanding, first, the relevant concepts in the method for the picture detection provided by the embodiments of the present application will be described.
The preset detection area is part or all of the area in the display panel. The preset detection area may include x minimum detection units, where x is a positive integer. The size of the preset detection area may be set according to requirements. For example, the preset detection area may include 9 minimum detection units.
The minimum detection unit includes at least one pixel, and each pixel includes three sub-pixels (red, green, blue (RGB)). That is to say, each minimum detection unit includes multiple sub-pixels.
Each sub-pixel on the display panel has its own corresponding grayscale value, and the grayscale value represents the luminous brightness of the sub-pixel. Generally, the grayscale value is a value between 0 and 255. The higher the value, the higher the brightness. In addition, it can be understood that the grayscale value of each sub-pixel in the display panel changes dynamically.
In the embodiments of the present application, the first type of sub-pixel (also called pixel on) refers to a sub-pixel, in a certain minimum detection unit, that has a grayscale value being greater than or equal to a default high grayscale value (H) corresponding to the minimum detection unit when the picture detection function is enabled, that is, the first type of sub-pixel is the sub-pixel, in the minimum detection unit, that has a relatively larger grayscale value and brighter brightness. For example, when the default high grayscale value (H) corresponding to a certain minimum detection unit is 60, the first type of sub-pixel refers to the sub-pixel in the minimum detection unit whose grayscale value is greater than or equal to 60.
In the embodiments of the present application, the second type of sub-pixel (also called Pixel off) refers to a sub-pixel, in a certain minimum detection unit, that has a grayscale value being smaller than or equal to a default low grayscale value (L) corresponding to the minimum detection unit when the picture detection function is enabled, that is, the second type of sub-pixel, is the sub-pixel, in the minimum detection unit, that has a relatively smaller grayscale value and darker brightness. For example, when the default low grayscale value (L) corresponding to a certain minimum detection unit is 40, the second type of sub-pixel refers to the sub-pixel in the minimum detection unit whose grayscale value is smaller than or equal to 40. It should be noted that the default low grayscale value is smaller than the default high grayscale value with respect to the same minimum detection unit.
The method for the picture detection provided by an embodiment of the present application will be explained in detail below.
First, a process of enabling the picture detection function is explained.
In step S101, grayscale values of all sub-pixels in a preset detection area are obtained.
As mentioned above, the grayscale values of sub-pixels in the display panel change dynamically. The grayscale values of sub-pixels are different when different frames are displayed.
Optionally, the display panel may periodically obtain the grayscale value of each sub-pixel in the preset detection area, and perform the following steps S102 to S104, or steps S201 to S203. In a particular embodiment, a period during which the display panel performs step S101 and other steps may be a refresh period of the picture. That is, the method according to the embodiment of the present application may be executed once every time a frame of picture is displayed by the display panel to determine whether to enable the picture detection function or to exit the picture detection function.
In step S102, it is determined whether each minimum detection unit in the preset detection area meets the respective hit condition (also called a second preset condition) when a picture detection function is in a disabled state, if the respective hit conditions are met, then step S103 is performed. If the respective hit conditions are not met, then step S104 is performed.
In the embodiment of the present application, the picture detection function refers to a picture detection function for the preset detection area. The picture detection function is in the disabled state means that the picture detection function has not been enabled, or the picture detection function has been enabled and then exited.
Each minimum detection unit has its own corresponding hit condition. In other words, x minimum detection units in the preset detection area are in a one-to-one correspondence with x hit conditions.
Particularly, taking any minimum detection unit in the preset detection area, such as the first minimum detection unit, as an example for explanation. The hit condition corresponding to the first minimum detection unit may be that: at least one sub-pixel of the first type and at least one sub-pixel of the second type are both presented in the first minimum detection unit. That is to say, the first minimum detection unit includes both the first type and the second type of sub-pixels.
It should be noted that in the embodiment of the present application, each minimum detection unit may have its own default high grayscale value (H) and default low grayscale value (L). That is to say, each minimum detection unit may have its own first type and second type of sub-pixels. For example, the default high grayscale value and the default low grayscale value corresponding to the minimum detection unit A is Ha and La. The default high grayscale value and the default low grayscale value corresponding to the minimum detection unit B may be Hb and Lb, then the first type of sub-pixel in the minimum detection unit A is a sub-pixel whose grayscale value is greater than or equal to Ha, and the second type of sub-pixel in the minimum detection unit A is a sub-pixel whose grayscale value is smaller than or equal to La. The first type of sub-pixel in the minimum detection unit B is a sub-pixel whose grayscale value is greater than or equal to Hb, and the second type of sub-pixel in the minimum detection unit B is a sub-pixel whose grayscale value is smaller than or equal to Lb. Each minimum detection unit has its own corresponding hit condition (i.e., the second preset condition) based on the default high grayscale value (H) and the default low grayscale value (L) corresponding thereto.
In this embodiment, the default high grayscale value corresponding to the first minimum detection unit is represented by Hn (also called a third value), and the default low grayscale value corresponding to the first minimum detection unit is represented by Ln (also called a fourth value), where Hn>Ln. Then, the hit condition corresponding to the first minimum detection unit may be expressed as: Pixelon≥Hn and Pixeloff≤Ln. For example, if Hn is 60 and Ln is 40, then the first type of sub-pixel in the first minimum detection unit is a sub-pixel whose grayscale value is greater than or equal to 60, and the second type of sub-pixel is a sub-pixel whose grayscale values is smaller than or equal to 40. In this case, if the first minimum detection unit includes both the sub-pixel whose grayscale value is greater than or equal to 60 and the sub-pixel whose grayscale value is smaller than or equal to 40, then it is determined that the first minimum detection unit meets the hit condition corresponded thereto.
Referring to the method for the first minimum detection unit, it is also determined whether the other minimum detection units meet their corresponding hit conditions. In case that each of the x minimum detection units meets its corresponding hit condition, then it is indicated that crosstalk or other abnormalities may occur in each current frame of picture, and the picture detection function needs to be enabled, and then step S103 is performed. In other cases, the step S104 is performed.
In step S103, the picture detection function is enabled.
In step S104, the picture detection function is maintained at the disabled state.
When the picture detection function is in the disabled state, if at least one minimum detection unit does not meet the hit condition corresponding to the minimum detection unit, then the picture detection function is maintained in the disabled state. That is to say, as long as one minimum detection unit does not meet the hit condition corresponding to the detection unit, indicating that no abnormal problem such as crosstalk is existed at this time, then there is no need to enable the picture detection function. At this time, the picture detection function continues to be in the disabled state.
Optionally, taking the first minimum detection unit as an example, the first minimum detection unit does not meet the hit condition corresponding to the first minimum detection unit may be that only one of sub-conditions of the corresponding hit condition is met, that is, the first minimum detection unit includes at least one sub-pixel of the first type, but no sub-pixel of the second type, or, the first minimum detection unit includes no sub-pixel of the first type but includes at least one sub-pixel of the second type. The formula may be expressed as: Pixelon≥Hn and Pixeloff>Ln, or alternatively, Pixelon<Hn and Pixeloff≤Ln. For example, if the default high grayscale value Hn is 60, and the default low grayscale value, i.e., the fourth value, Ln is 40, and in the next frame there is a minimum detection unit in which the grayscale values of all sub-pixels are greater than 40, then the corresponding hit condition is not met at this time, the picture detection function will continue to be in the disabled state.
It is noted based on research that crosstalk is caused by uneven polarities of sub-pixels in the display panel, and uneven polarity is due to the presence of both light and dark in the picture. As shown in
A method for enabling a picture detection function is provided in an embodiment of the present application, which includes steps of: determining whether each minimum detection unit meets the second preset condition corresponding thereto when the picture detection function is in the disabled state; and enabling the picture detection function when each minimum detection unit meets the second preset condition corresponding thereto. It can be determined based on the second preset condition in this embodiment whether the brightness of the picture is uniform. If each minimum detection unit meets the second preset condition corresponding thereto, then it is indicated that the brightness of the current picture is uneven and the polarity of the sub-pixels is uneven, and then the picture detection function is enabled. This method combines the cause of crosstalk to set the hit conditions for enabling the picture detection function. The picture detection function can be enabled when crosstalk occurs, which avoids false triggering of enabling PDF, thus, the picture detection function will be more accurate. Moreover, due to the hit conditions, the PDF is maintained at the disabled state when crosstalk does not occur, that is, the picture detection function is disabled, thereby saving resources.
The following describes the process of enabling the picture detection function and the process of sub-pixel polarity inversion.
In one embodiment, the default high grayscale value and the default low grayscale value are respectively determined based on original grayscale values of all sub-pixels in the first minimum detection unit.
The original grayscale values refer to the grayscale values of the sub-pixels before the picture detection function is enabled. Particularly, the maximum grayscale value and the minimum grayscale value among the original grayscale values of all sub-pixels in the first minimum detection unit can be obtained. Hn and Ln are determined based on the maximum grayscale value and the minimum grayscale value, where Hn and Ln are both smaller than the maximum grayscale value, and both are greater than the minimum grayscale value. In other words, Hn and Ln are between the maximum grayscale value and the minimum grayscale value in the first minimum detection unit. In this way, the first type of sub-pixel(s) and the second type of sub-pixel(s) in the first minimum detection unit can be determined based on Hn and Ln, covering all grayscale situations in the first minimum detection unit, and the relative brightness and darkness relevant to grayscale values of the sub-pixels in the first minimum detection unit can be determined, and then the corresponding second preset condition can be determined, thereby the accuracy of the picture detection function is improved.
In step S201, it is determined whether at least one of the minimum detection units meets an exit condition (also called a first preset condition) corresponding thereto when the picture detection function is enabled. If at least one of the minimum detection units meets the exit condition corresponding thereto, then step S202 is performed; and if each of the minimum detection units does not meet the exit condition corresponding thereto, then step S203 is performed.
It should be noted that only when the picture detection function is enabled will it be judged whether the exit conditions need to be met, that is, whether the picture detection function needs to be exited. Similar to the hit condition, each minimum detection unit also has its own corresponding exit condition. In other words, x minimum detection units in a preset detection area are in a one-to-one correspondence with x exit conditions.
Particularly, taking the first minimum detection unit as an example, the exit condition corresponding to the first minimum detection unit is that: the grayscale value of at least one sub-pixel of the first type is smaller than or equal to a first value, or the grayscale value of at least one sub-pixel of the second type is greater than or equal to a second value, and the first value is greater than the second value.
It should be noted that for the same minimum detection unit, its first value (H−A) is smaller than the preset high grayscale value (H), and its second value (L+B) is greater than the default low grayscale value (L). Therefore, in the following embodiments, the first value is expressed as H−A, and the second value is expressed as L+B, where A>0, B>0, and H−A is greater than L+B. Then, the exit condition corresponding to a certain minimum detection unit can be expressed as: Pixelon≤H−A or Pixeloff≥L+B.
It can be understood that picture detection is a real-time detection. If the picture detection function is enabled when the display panel displays the n-th frame of picture, then the step of determining whether the first preset condition is met is required when displaying each frame of picture after the n-th frame of picture, to determine whether to exit the picture detection function. Continuing to take the first detection unit as an example, if the n-th frame of picture is displayed (that is, the picture detection function is enabled), it is determined that Hn is 60 and Ln is 40, and it is assumed that A is 5 and B is 5, then the first value is 55, the second value is 45. Then, during displaying of each frame of picture after the (n+1)-th frame of picture, if in the first detection unit, at least one sub-pixel of the first type has a grayscale pixel value being smaller than or equal to 55, or at least one sub-pixel of the second type has a grayscale value being greater than or equal to 45, then it is determined that the first frame measurement unit meets its exit condition. At this time, it can be determined that the conditions for exiting the picture detection function are currently met, and the picture detection function can be exited. If the first detection unit does not meet its exit condition, then it is further determined whether the next minimum detection unit meets the exit condition corresponding thereto. By analogy, until it is determined that one of the x minimum detection units meets its corresponding exit condition, then the picture detection function is exited.
In step S202, the picture detection function is exited.
It should be noted that in case that the picture detection function is enabled, the picture detection function enables the polarity to be reversed to achieve a uniform polarity distribution. In case that the picture detection function is enabled, if the first preset condition is met, then it is indicated that the grayscale value of the sub-pixel in the preset detection area has changed, and the brightness has also changed, which then indicates that the polarity has become uneven. At this time, it is necessary to exit the picture detection function, no longer continue to perform polarity reversal, to maintain the uniformity of polarity.
In step S203, the picture detection function is maintained at an enabled state.
That is to say, in case that the picture detection function is enabled, if the x minimum detection units do not meet the corresponding exit conditions, then it is indicated that the phenomenon of crosstalk is still existed, and then the picture detection function continues to be maintained at the enabled state.
Optionally, taking the first detection unit as an example, the exit condition corresponding to the first minimum detection unit is not met may be that: the grayscale value of the first type of sub-pixel is greater than the first value (H−A) and smaller than the default high grayscale value (H); and the grayscale value of the second type of sub-pixel is smaller than the second value (L+B), the formula may be expressed as: H−A<Pixelon<H and Pixeloff<L+B. The exit condition corresponding to the first minimum detection unit is not met may also be that: the grayscale value of the first type of sub-pixel is greater than or equal to the default high grayscale value (H); and the grayscale value of the second type of sub-pixel is greater than the default low grayscale value (L) and smaller than the second value (L+B), the formula may be expressed as Pixelon≥H and L<Pixeloff<L+B. By analogy, until all of the x minimum detection units do not meet their respective exit condition, then the picture detection function will continue to be maintained at the enabled state.
As mentioned above, crosstalk is caused by the uneven polarity of sub-pixels in the display panel, and the uneven polarity is due to the presence of both light and dark in the picture. For a completely black picture, the grayscale values of all sub-pixels are 0 and the polarities of all sub-pixel are uniform, so the impact of the data voltage on VCOM can be ignored.
In the method provided by the embodiments of the present application, the exit condition can cover a display screen where the polarities are uniformly distributed, thereby the problem of inaccurate PDF exit in related technologies can be solved. As illustrated with reference to
As an example,
In the method provided by the embodiment of the present application, the exit condition corresponding to each minimum detection unit is that: Pixelon≤H−A or Pixeloff≥L+B. For the picture shown in
It can be seen that the method for the picture detection provided by the embodiment of the present application closely combines the crosstalk causes with the conditions for exiting the picture detection function by improving the conditions for exiting the picture detection function, so that the conditions for exiting the picture detection function can cover the entire black or full bright screen, and other situations where the polarity distribution is even and the picture detection function needs to exit. For pictures that will not cause crosstalk, the picture detection function is excluded (exited) which improves the accuracy of the picture detection function and avoids waste of resources.
