[0044] The present disclosure will now be described in more detail with reference to the following examples. It should be noted that the following description of some of the embodiments presented herein is for illustration and description purposes only. It is not intended to be exhaustive or limited to the precise form disclosed.
[0045] Figure 1A The first image displayed by the display panel is shown. The first image has a checkerboard pattern including one or more dark areas (black) and one or more bright areas (white). Figure 1B 1 shows a second image displayed by the display panel after displaying the first image for a period of time. In one example, the first image is displayed for six hours before switching to the second image. The second image is intended to be a full white image. However, as Figure 1B As shown, one or more light regions in the first image appear darker in the second image compared to one or more dark regions in the first image. Figure 1A and Figure 1B The phenomenon shown in is an example of image retention or screen burn-in, which may occur due to prolonged exposure to static images.
[0046] In the pixel driving circuit of the display panel, the relationship between the driving current and the threshold voltage of the driving transistor can be expressed as:
[0047] Id=k*(Vgs-Vth) 2
[0048] Among them, Id represents the driving current of the pixel driving circuit, Vgs represents the gate-source voltage, Vth represents the threshold voltage of the driving transistor, and k is a parameter that depends on the physical characteristics of the driving transistor. The k parameter, also known as the transconductance parameter or device gain factor, represents the slope of the Id-Vgs curve and determines the strength of the amplification or switching capability of the transistor. It depends on the physical size and properties of the transistor, such as channel width and channel length.
[0049] The inventors of the present disclosure have found that, at least in organic light-emitting display panels, the main factors contributing to afterimages are the threshold voltage and parameter k of the drive transistor. Long-term positive stress, light exposure, and temperature fluctuations can cause Vth to shift positively or negatively, leading to irregularities such as afterimages in the display panel.
[0050] When the display panel displays an image in a region of the display panel for a long time, an afterimage occurs. For example, when the display panel displays a TV station logo for a long time, an afterimage occurs.
[0051] The present disclosure provides, among other things, a display device, a method for displaying an image, and a computer program product, which substantially eliminate one or more problems caused by the limitations and disadvantages of the prior art. In one aspect, the present disclosure provides a display device. In some embodiments, the display device includes a display panel; a memory; and one or more processors. Optionally, the memory is connected to one or more processors; and the memory stores computer executable instructions, which are used to control the one or more processors to perform the following operations: detecting an area configured to display a static image in a display panel; in the area configured to display the static image, detecting the parameters of the driving transistor of the sub-pixel of the first color within a first time period, and detecting the parameters of the driving transistor of the sub-pixel of the second color within a second time period; determining the sub-pixel value of the sub-pixel in the corresponding pixel in the static image in the corresponding image frame including the static image; converting the sub-pixel value of the sub-pixel in the corresponding pixel in the static image to the brightness value of the sub-pixel in the corresponding pixel in the static image; reducing the first brightness value of the first sub-pixel in the corresponding pixel to a first adjusted brightness value; and converting the first adjusted brightness value of the first sub-pixel in the corresponding pixel in the static image to a first adjusted sub-pixel value. Optionally, the parameters of the driving transistor of the sub-pixel of the first color are detected at a first frequency. Optionally, the parameters of the driving transistor of the sub-pixel of the second color are detected at a second frequency. Optionally, the first frequency is higher than the second frequency.
[0052] Figure 2 2 shows an image displayed on a display panel according to some embodiments of the present disclosure. Figure 2, the display panel is configured to display a static image in the first region R1 for a period of time greater than a threshold value (in Figure 2 LOGO" in the figure). Examples of static images include, but are not limited to, digital on-screen graphics, such as a logo that appears in the corner of the screen, typically showing the name or logo of a television network, and which is used to identify the network or program being broadcast. The threshold value can be, for example, greater than 5 minutes, greater than 10 minutes, greater than 15 minutes, greater than 20 minutes, greater than 25 minutes, greater than 30 minutes, greater than 35 minutes, greater than 40 minutes, greater than 45 minutes, greater than 50 minutes, greater than 55 minutes, greater than 1 hour, greater than 2 hours, greater than 3 hours, greater than 4 hours, greater than 5 hours, greater than 6 hours, greater than 7 hours, greater than 8 hours, greater than 9 hours, or greater than 10 hours.
[0053] In some embodiments, the display panel is configured to display dynamic images in a second area R2 outside the first area R1. As used herein, the term "dynamic image" refers to a visual element that contains motion or animation and changes over time. Examples of dynamic images include videos, animated graphics, or any other visual content that contains movement. As used herein, the term "static image" refers to a visual element that does not change and remains fixed on the screen. It is a digital representation that does not contain animation or motion. Examples of static images include graphics, logos, icons, and photos on a digital screen. As described above, problems with afterimages or burn-in are prone to occur in an area (e.g., the first area R1) configured to display a static image.
[0054] Although the display panel is configured to display a static image in the first region R1, the display panel may also display or not display a dynamic image in the first region R1 at the same time. In one example, the display panel is configured to exclusively display a static image in the first region R1. In another example, the display panel is configured to simultaneously display a static image and a dynamic image in the first region R1.
[0055] Figure 3 is a flowchart illustrating a method for displaying an image in some embodiments of the present disclosure. Figure 3 , a method for displaying an image includes detecting an area configured to display a static image. In some embodiments, the method includes analyzing a video stream in real time, for example by scanning sub-pixels of the video stream and identifying any areas that match the characteristics of the static image. Various suitable characteristics can be used to identify static images. Examples of suitable characteristics include size, shape, color, and position. Various suitable image processing algorithms can be used to analyze the video stream. Examples of image processing algorithms that can be used include various suitable image segmentation algorithms, such as thresholding or clustering. Image segmentation algorithms can separate static images from dynamic images or background images.
[0056] Image segmentation algorithms are configured to divide an image into multiple regions or fragments based on its visual characteristics (e.g., color, texture, or shape). In one example, a thresholding algorithm can be used to separate an image into different fragments based on a user-defined threshold. Pixels with intensities above a threshold are classified as one fragment, while pixels below a threshold are classified as another fragment. In another example, a clustering algorithm can be used to group pixels together based on the similarity of the pixels in color or other visual features. Examples of clustering algorithms include a k-means algorithm, which groups pixels into k clusters based on the distance of the pixels from the cluster center. In another example, an edge-based segmentation algorithm can be used to identify edges in an image and use them to separate the image into different fragments. Examples of edge-based segmentation algorithms include a Canny edge detector, which uses gradient information to identify edges in an image. In another example, a region-based segmentation algorithm can be used to divide an image into multiple regions based on the uniformity of the image in color or other visual features. Examples of region-based segmentation algorithms include a watershed algorithm, which treats an image as a topographic map and identifies regions based on the boundaries between different watersheds. In another example, a contour-based segmentation algorithm can be used to identify contours in an image and use them to separate the image into different segments. Examples of contour-based segmentation algorithms include active contours or snake algorithms, which iteratively adjust the position of contours to fit the boundaries of objects in the image.
[0057] In some embodiments, the method further comprises determining a sub-pixel value of a sub-pixel in a corresponding pixel in the static image in a corresponding image frame comprising the static image. The sub-pixel value is typically in the range of 0 to 255. In one example, the sub-pixel value is a grayscale value of the sub-pixel. The higher the sub-pixel value, the higher the brightness or intensity of the light emitted by the sub-pixel. In one example, the method comprises extracting a corresponding image frame from a plurality of image frames, such as in a video stream; and determining a sub-pixel value of a sub-pixel in a corresponding pixel in the static image in a corresponding image frame comprising the static image.
[0058] In some embodiments, each pixel includes a plurality of sub-pixels of different colors. Optionally, each pixel includes a first sub-pixel of a first color and a second sub-pixel of a second color. Optionally, each pixel also includes a third sub-pixel of a third color. Optionally, each pixel also includes a fourth sub-pixel of a fourth color. In one example, the first color is blue, the second color is white, the third color is red, and the fourth color is green.
[0059] In some embodiments, the method further comprises converting the sub-pixel value of the sub-pixel in the corresponding pixel in the static image into the brightness value of the sub-pixel in the corresponding pixel in the static image. Various suitable methods can be used to convert the sub-pixel value of the sub-pixel in the corresponding pixel in the static image into the brightness value of the sub-pixel in the corresponding pixel in the static image. In some embodiments, the sub-pixel value can be converted into the brightness value using a gamma value.
[0060] In some embodiments, the gamma value is expressed as:
[0061]
[0062] In some embodiments, a gamma value curve or a gamma value table may be used. Optionally, the method includes converting the sub-pixel values of the sub-pixels in the corresponding pixels in the static image into the brightness values of the sub-pixels in the corresponding pixels in the static image using the gamma value table or the gamma value curve.
[0063] In one example, the maximum sub-pixel value is 255.
[0064] Gamma is a parameter used to describe the relationship between sub-pixel values in a digital image and the corresponding brightness values they represent. Gamma is a measure of the linearity or nonlinearity of a display's response to changes in input voltage. A gamma value of 1.0 indicates a linear response, while values greater than 1.0 indicate a non-linear response, where mid-tone values are boosted in brightness. A gamma value of 1.0 means that brightness values increase or decrease linearly with pixel values. Gamma is important in accurately reproducing image content on a display, especially when viewing images across different devices with varying gamma values.
[0065] The gamma values of sub-pixels of different colors (eg, red, green, and blue) may be different because the human eye responds differently to different colors of light. Figure 4A The correlation between the luminance value of a first sub-pixel of a first color and the sub-pixel value is shown according to some embodiments of the present disclosure. Figure 4B 1 shows the correlation between the brightness value and the sub-pixel value of the second sub-pixel of the second color according to some embodiments of the present disclosure. In one example, the first color is blue and the second color is white. In another example, the first sub-pixel is a blue sub-pixel and the second sub-pixel is a white sub-pixel. Figure 4A and Figure 4B As shown, for the same sub-pixel value, a first sub-pixel of a first color has a much smaller corresponding brightness value than a second sub-pixel of a second color.
[0066] In some embodiments, the method further includes reducing at least a first brightness value of a first sub-pixel in the corresponding pixel to a first adjusted brightness value; increasing at least a second brightness value of a second sub-pixel in the corresponding pixel to a second adjusted brightness value, wherein the second sub-pixel requires a smaller sub-pixel value than the first sub-pixel to achieve the same brightness value. By reducing at least a first brightness value of a first sub-pixel in the corresponding pixel to the first adjusted brightness value and increasing at least a second brightness value of a second sub-pixel in the corresponding pixel to the second adjusted brightness value, afterimages caused by displaying a static image at the same location for an extended period of time can be reduced or avoided.
[0067] In some embodiments, after reducing at least a first brightness value of a first subpixel in a corresponding pixel to a first adjusted brightness value and increasing at least a second brightness value of a second subpixel in a corresponding pixel to a second adjusted brightness value, the total brightness value of the subpixels of the corresponding pixel remains substantially the same. As used herein, the term "substantially the same" means that the difference between two values does not exceed 10% of a base value (e.g., one of the two values), such as not more than 8%, not more than 6%, not more than 4%, not more than 2%, not more than 1%, not more than 0.5%, not more than 0.1%, not more than 0.05%, and not more than 0.01% of the base value. For example, the reduced brightness value of at least the first subpixel is substantially the same as the increased brightness value of at least the second subpixel.
[0068] In some embodiments, the method further includes converting the adjusted brightness value of the sub-pixel in the corresponding pixel in the static image to the adjusted sub-pixel value of the sub-pixel in the corresponding pixel in the static image; and using the adjusted sub-pixel value to display the static image. For example, the method further includes converting the first adjusted brightness value to the first adjusted sub-pixel value and converting the second adjusted brightness value to the second adjusted sub-pixel value, and using the first adjusted sub-pixel value of the first sub-pixel and the second adjusted sub-pixel value of the second sub-pixel to display the static image.
[0069] Various suitable embodiments can be practiced according to the present disclosure. Figure 5 is a diagram illustrating brightness values of sub-pixels in corresponding pixels according to some embodiments of the present disclosure. Figure 6 is a flowchart illustrating a method of displaying an image according to some embodiments of the present disclosure. Figure 5 and Figure 6In some embodiments, a method for displaying an image includes detecting an area configured to display a static image; determining a sub-pixel value of a sub-pixel in a corresponding pixel in the static image in a corresponding image frame including the static image; determining a sub-pixel value of a sub-pixel in a corresponding pixel in the static image in a corresponding image frame including the static image; converting the sub-pixel value of the sub-pixel in the corresponding pixel in the static image into a brightness value of the sub-pixel in the corresponding pixel in the static image; reducing a first brightness value of a first sub-pixel sp1 in the corresponding pixel to a first adjusted brightness value; reducing a third brightness value of a third sub-pixel sp3 in the corresponding pixel to a third adjusted brightness value; and increasing a fourth brightness value of a fourth sub-pixel sp4 in the corresponding pixel to a third adjusted brightness value. The value is reduced to a fourth adjusted brightness value; the second brightness value of the second sub-pixel sp2 in the corresponding pixel is increased to the second adjusted brightness value; the first adjusted brightness value of the first sub-pixel sp1 in the corresponding pixel in the static image is converted to the first adjusted sub-pixel value; the second adjusted brightness value of the second sub-pixel sp2 in the corresponding pixel in the static image is converted to the second adjusted sub-pixel value; the third adjusted brightness value of the third sub-pixel sp3 in the corresponding pixel in the static image is converted to the third adjusted sub-pixel value; the fourth adjusted brightness value of the fourth sub-pixel sp4 in the corresponding pixel in the static image is converted to the fourth adjusted sub-pixel value; and the static image is displayed using the first adjusted sub-pixel value, the second adjusted sub-pixel value, the third adjusted sub-pixel value and the fourth adjusted sub-pixel value.
[0070] In some embodiments, to achieve the same brightness value, the second sub-pixel requires a smaller sub-pixel value than the first sub-pixel. Alternatively, to achieve the same brightness value, the third sub-pixel requires a smaller sub-pixel value than the first sub-pixel. Alternatively, to achieve the same brightness value, the fourth sub-pixel requires a smaller sub-pixel value than the first sub-pixel.
[0071] Reference Figure 5 In some embodiments, the first brightness value of the first sub-pixel sp1 in the corresponding pixel is reduced by the first brightness difference Δlv1 to obtain a first adjusted brightness value, the third brightness value of the third sub-pixel sp3 in the corresponding pixel is reduced by the third brightness difference Δlv3 to obtain a third adjusted brightness value, the fourth brightness value of the fourth sub-pixel sp4 in the corresponding pixel is reduced by the fourth brightness difference Δlv4 to obtain a fourth adjusted brightness value, and the second brightness value of the second sub-pixel sp2 in the corresponding pixel is increased by the second brightness difference Δlv2 to obtain a second adjusted brightness value.
[0072] In some embodiments, the second brightness difference Δlv2 is substantially the same as the sum of the first brightness difference Δlv1, the third brightness difference Δlv3, and the fourth brightness difference Δlv4. By making the second brightness difference Δlv2 substantially the same as the sum of the first brightness difference Δlv1, the third brightness difference Δlv3, and the fourth brightness difference Δlv4, the total brightness values of the corresponding pixels remain substantially the same.
