Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a method, apparatus, electronic device, and display panel for improving image retention on a display panel. Background Technology

[0002] Currently, with the rapid development of display technology, various new display products are emerging one after another. In the display field, especially in the field of OLED (Organic Light-Emitting Diode) display, high brightness is the current market requirement for display panels. When displaying images, the high data voltage in the high-brightness display area leads to severe degradation of the light-emitting device material. The VTH (Threshold Voltage) of the TFT (Thin Film Transistor) in the light-emitting device drifts rapidly, causing image retention on the display panel. Related technologies perform voltage compensation on all pixels in the high-brightness display area to adjust the image and avoid visual defects. However, adjusting the voltage of all pixels involves a large amount of processing and high energy consumption. Therefore, there is an urgent need for a simple and efficient method to improve the image retention of display panels. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a method, apparatus, electronic device and display panel for improving image retention on a display panel.

[0004] A first aspect of this application provides a method for improving image retention in a display panel, comprising: obtaining a bright display area and a non-bright display area of ​​the display panel, wherein a pixel located at the edge of the bright display area is a first pixel, and a pixel close to the first pixel and located in the non-bright display area is a second pixel; adjusting the original voltage of a portion of the second pixels to a first voltage based on the original voltage of the first pixel, wherein the second pixels whose voltages are adjusted are arranged in a dispersed or irregular manner.

[0005] In some embodiments, adjusting the original voltage of a portion of the second pixels near the first pixel to a first voltage based on the original voltage of the first pixel, wherein the arrangement of the second pixels undergoing voltage adjustment is dispersed or irregular, includes: exchanging the original voltage of the first pixel with the original voltage of a portion of the second pixels, such that the voltage of the second pixel is the first voltage and the voltage of the first pixel is the second voltage, and the second pixels undergoing voltage exchange are spaced apart.

[0006] In some embodiments, the step of swapping the original voltage of the first pixel with the original voltage of a portion of the second pixel includes: swapping the voltage of a portion of the first pixel with the voltage of the second pixel adjacent to the first pixel, such that the first pixel that has not undergone voltage swapping is spaced apart from the second pixel that has undergone voltage swapping.

[0007] In some embodiments, the step of swapping the original voltage of the first pixel with the original voltage of a portion of the second pixel includes: swapping the voltage of all the first pixels with the voltage of the second pixels located in the diffusion direction of the first pixel.

[0008] In some embodiments, adjusting the original voltage of a portion of the second pixels to a first voltage based on the original voltage of the first pixel, wherein the arrangement of the second pixels undergoing voltage adjustment is dispersed or irregular, includes: adjusting the original voltage of the second pixels along the diffusion direction of the first pixel to a first voltage, wherein the first voltage of the second pixel is less than the original voltage of the first pixel and greater than the original voltage of other second pixels adjacent to the second pixel.

[0009] In some embodiments, adjusting the original voltage of the second pixel along the diffusion direction of the first pixel to a first voltage includes: adjusting the original voltage of at least two second pixels closest to the first pixel to a first voltage along the diffusion direction of the first pixel, such that the original voltage of the first pixel and the first voltage of the at least two second pixels decrease along the diffusion direction.

[0010] In some embodiments, obtaining the highlight display area and non-highlight display area of ​​the display panel includes: obtaining the original voltage of each pixel in the display panel; and determining the highlight display area and non-highlight display area of ​​the display panel according to a preset high-brightness voltage threshold and the original voltage.

[0011] In some implementations, the number of pixels between the first pixel and the second pixel is less than or equal to a preset number.

[0012] In some embodiments, the method for improving display panel afterimages further includes: adjusting the original voltage of the pixels in the high-brightness display area to a third voltage at a preset frequency, wherein the third voltage is less than the original voltage of the corresponding pixel.

[0013] In some implementations, the third voltage is 0, or is scaled down proportionally to the original voltage of the corresponding pixel.

[0014] A second aspect of this application provides an apparatus for improving image retention on a display panel, comprising: an acquisition module configured to acquire a bright display area and a non-bright display area of ​​the display panel, wherein pixels located at the edge of the bright display area are first pixels, and pixels close to the first pixel and located in the non-bright display area are second pixels; and a voltage adjustment module configured to adjust the original voltage of a portion of the second pixels to a first voltage based on the original voltage of the first pixel, wherein the second pixels undergoing voltage adjustment are arranged in a dispersed or irregular manner.

[0015] A third aspect of this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the method for improving display panel retention as described in the first aspect above.

[0016] A fourth aspect of this application provides a display panel, including the means for improving display panel image retention as described in the second aspect above or the electronic device as described in the third aspect above.

[0017] A fifth aspect of this application provides a computer-readable storage medium storing computer instructions for causing the computer to perform the method for improving display panel retention as described in the first aspect above.

[0018] As can be seen from the above description, this application provides a method, apparatus, electronic device, and display panel for improving display panel image retention. It obtains the bright and non-bright areas of the display panel, identifies pixels located at the edge of the bright area as first pixels, and identifies pixels close to the first pixel and located in the non-bright area as second pixels, providing a basis for subsequent voltage adjustment. Based on the original voltage of the first pixel, the original voltage of some second pixels is adjusted to the first voltage. Furthermore, the second pixels undergoing voltage adjustment are arranged in a dispersed or irregular manner, thus adjusting the pixels near the boundary of the bright area, visually interfering with the original bright area image retention. The method blurs the boundary between the highlighted and non-highlighted display areas, making the distinction between them indistinct. Visually, users only see a blurred image boundary, thus minimizing the perception of image retention. Furthermore, this method only processes a portion of the second pixels near the first pixel, eliminating the need to process all pixels in the highlighted display area, significantly reducing processing load and energy consumption. This method, device, electronic device, and display panel for improving display panel image retention are simple and convenient. They effectively blur the visual boundary between the highlighted and non-highlighted display areas, minimizing image retention, improving image retention, and offering a high-quality user experience with low processing load and energy consumption.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0035] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

[0036] Currently, with the rapid development of display technology, various new display products are emerging one after another. In the display field, especially in the field of OLED (Organic Light-Emitting Diode) display, high brightness is the current market requirement for display panels. When displaying images, because the data voltage in the high-brightness display area is large, the light-emitting device material deteriorates severely. The VTH (Threshold Voltage) of the TFT (Thin Film Transistor) in the light-emitting device will drift, resulting in image retention on the display panel. Excessive data voltage writing causes excessive light-emitting current and excessive local temperature rise of the light-emitting device, making VTH drift faster and thus causing image retention to be more severe.

[0037] Related technologies perform voltage compensation on all pixels in the high-brightness display area to adjust the image and avoid visual defects. However, adjusting the voltage of all pixels involves a large amount of processing and high energy consumption, and it also accelerates material degradation. Therefore, there is an urgent need for a simple and efficient method to improve display panel image retention.

[0038] In the process of implementing this application, it was discovered that the edges of the bright display area of ​​the display panel are usually relatively flat and regular, and there is a clear difference between the bright display area and the non-bright display area. This makes it obvious that users can see a relatively obvious image retention boundary when viewing the display screen, and the image retention is obvious. Therefore, it is possible to consider blurring the edges of the bright display area to make the edges dispersed or irregular. In this way, users will not see obvious image retention boundaries, and the image retention will be less obvious. Moreover, processing only the pixels near the edges is less complex and consumes less power compared to processing all pixels in the bright display area.

[0039] The following describes specific embodiments in conjunction with... Figures 1 to 13 The technical solution of this application will be described in detail below.

[0040] Some embodiments of this application provide a method for improving image retention on a display panel, such as... Figure 1 As shown, it includes the following steps:

[0041] S1. Obtain the highlight display area 1 and the non-highlight display area 2 of the display panel. The pixel located at the edge of the highlight display area 1 is the first pixel 1-1, and the pixel close to the first pixel 1-1 and located in the non-highlight display area 2 is the second pixel 2-1.

[0042] like Figure 2 The diagram shows a display panel. Based on the original voltage of each pixel, the display panel can be divided into a high-brightness display area 1 and a non-high-brightness display area 2. Figure 3 and Figure 6 As shown, the pixel located at the edge of the highlighted display area 1 is the first pixel 1-1, and the pixel close to the first pixel 1-1 and located in the non-highlighted display area 2 is the second pixel 2-1. The edge can be defined as the ring of pixels within the highlighted display area 1 that is closest to the non-highlighted display area 2, or it can be defined as several rings of pixels within the highlighted display area that are closest to the non-highlighted display area 2. There is no specific limitation. The second pixel 2-1 is any pixel within several rings of the first pixel 1-1, which can be set according to requirements. Determining the first pixel 1-1 and the second pixel 2-1 provides a basis for subsequent voltage adjustment.

[0043] S2. Based on the original voltage of the first pixel 1-1, the original voltage of some of the second pixels 2-1 is adjusted to the first voltage, and the second pixels 2-1 that have undergone voltage adjustment are arranged in a scattered or irregular manner.

[0044] Based on the original voltage of the first pixel 1-1, the original voltage of some of the second pixels 2-1 is adjusted to the first voltage, and the second pixels 2-1 that have undergone voltage adjustment are scattered or irregular in arrangement, such as... Figure 3 and Figure 6 As shown, the pixels near the boundary of the highlighted display area 1 were adjusted, visually interfering with the original boundary between the highlighted display area 1 and the non-highlighted display area 2. This makes the distinction between the highlighted display area 1 and the non-highlighted display area 2 indistinct. Figure 3 and Figure 6 As shown, the adjusted display panel forms a new set of bright pixels 3. Visually, the user will only see a blurred boundary, and the afterimage will not be obvious. Furthermore, this method only processes a portion of the second pixels 2-1, without processing all the pixels in the bright display area 1, which greatly reduces the processing load and energy consumption.

[0045] This method for improving display panel image retention is simple and convenient. It can effectively blur the visual boundary between the bright display area 1 and the non-bright display area 2, making the image retention less noticeable, thus improving the image retention phenomenon. It has low processing power, low energy consumption, and high user experience.

[0046] In some embodiments, step S1 includes:

[0047] S11. Obtain the original voltage of each pixel in the display panel.

[0048] like Figure 2 The voltage values ​​of each pixel shown are the original voltages.

[0049] S12. Determine the high-brightness display area 1 and the non-high-brightness display area 2 of the display panel according to the preset high-brightness voltage threshold and the original voltage.

[0050] The preset high-brightness voltage threshold is, for example, 7V, but the specific value is not limited. The area formed by pixels with original voltages greater than or equal to the high-brightness voltage threshold is defined as the high-brightness display area 1, and the area formed by pixels with voltages less than the high-brightness voltage threshold is defined as the non-high-brightness display area 2. The new high-brightness pixel set 3 in other figures is also determined based on this high-brightness voltage threshold. That is, the voltage of each pixel after adjustment is compared with the high-brightness voltage threshold, and the combination of pixels with voltages greater than or equal to the high-brightness voltage threshold is the new high-brightness pixel set 3. However, the edges of this set may have scattered pixel arrangement and cannot form a closed area.

[0051] In some embodiments, the number of pixels between the first pixel 1-1 and the second pixel 2-1 is less than or equal to a preset number.

[0052] The preset number is, for example, 0 to 3, with no specific limit. When the preset number is 0, the first pixel 1-1 and the second pixel 2-1 are adjacent. When the preset number is greater than 0, the second pixel 2-1 is within a few rings of pixels that spread outward from the first pixel 1-1. Limiting the distance between the first pixel 1-1 and the second pixel 2-1 is to avoid the second pixel 2-1 being too far away from the first pixel 1-1. This way, even if the voltage of the second pixel 2-1 is adjusted, it will not visually interfere with the afterimage boundary.

[0053] In some embodiments, step S2 includes:

[0054] S21. The original voltage of the first pixel 1-1 is interchanged with the original voltage of a portion of the second pixel 2-1, so that the voltage of the second pixel 2-1 is the first voltage and the voltage of the first pixel 1-1 is the second voltage, and the second pixels 2-1 that have undergone voltage interchange are spaced apart.

[0055] like Figure 3 As shown, the adjustment method for the second pixel 2-1 is to swap its original voltage with that of the first pixel 1-1. This results in the second pixel 2-1 having a larger first voltage. The second pixel 2-1 forms the boundary of the new bright pixel set 3. Because the second pixels 2-1 with swapped voltages are spaced apart, the boundary of the new bright pixel set 3 is dispersed, and visually there is no obvious difference between the bright display area 1 and the non-bright display area 2, thus improving the image retention phenomenon. Furthermore, because the voltage of the first pixel 1-1 becomes a smaller second voltage, the boundary of the original bright display area 1 is also destroyed, further blurring the image retention boundary and improving the image retention phenomenon. Moreover, the smaller voltage of the first pixel 1-1 can reduce the degradation rate of the material, further improving the image retention phenomenon.

[0056] In some embodiments, the step of swapping the original voltage of the first pixel 1-1 with a portion of the original voltage of the second pixel 2-1 includes:

[0057] S2101, swap the voltage of a portion of the first pixel 1-1 with the second pixel 2-1 that is close to the first pixel 1-1, so that the first pixel 1-1 that has not been swapped with the voltage and the second pixel 2-1 that has been swapped with the voltage are spaced apart.

[0058] like Figure 4As shown, the voltage of some first pixels 1-1 is swapped with that of the second pixels 2-1 that are close to the first pixels 1-1. The first pixels 1-1 that have not undergone voltage swapping are spaced apart from the second pixels 2-1 that have undergone voltage swapping. Compared with adjusting all the first pixels 1-1, this method can ensure that the edges of the new set of bright pixels 3 after adjustment are dispersed, improve afterimages, and reduce the amount of pixel adjustment. It is less processing and more efficient.

[0059] In some embodiments, the step of swapping the original voltage of the first pixel 1-1 with a portion of the original voltage of the second pixel 2-1 includes:

[0060] S2102, swap the voltage of all first pixels 1-1 with the second pixels 2-1 located in the diffusion direction of the first pixels 1-1.

[0061] The diffusion direction is the direction from the interior of the highlighted display area 1 towards the first pixel 1-1. Each first pixel 1-1 has only one diffusion direction. Figure 5 As shown, taking the first pixel 1-1 in the lower left corner of the highlighted display area 1 as an example, its diffusion direction is as shown by the white arrow in the figure, that is, from the 9.1V pixel to the 7.6V pixel.

[0062] By swapping the voltage of all first pixels 1-1 with the second pixels 2-1 located in the diffusion direction of the first pixels 1-1, the boundary of the original bright display area 1 can be completely broken, making the visual boundary unclear and improving the afterimage phenomenon; and it is more convenient to process than randomly shuffling the arrangement of the second pixels 2-1.

[0063] In some embodiments, the second pixels 2-1 corresponding to two adjacent first pixels 1-1 that have their voltages swapped are spaced apart.

[0064] like Figure 9 and Figure 10 The diagram shows another type of display panel. The highlighted display area 1 is a 4*3 rectangle. At the top of the highlighted display area 1, there are two adjacent first pixels 1-1 with a voltage of 9.3V. When the voltage of the first pixel 1-1 is swapped, the selected second pixels 2-1 are set at intervals. This ensures that the boundaries of the new highlighted pixel set 3 are dispersed, effectively improving the afterimage phenomenon.

[0065] In some embodiments, step S2 includes:

[0066] S22. Adjust the original voltage of the second pixel 2-1 along the diffusion direction of the first pixel 1-1 to a first voltage. The first voltage of the second pixel 2-1 is less than the original voltage of the first pixel 1-1 and greater than the original voltage of other second pixels 2-1 adjacent to the second pixel 2-1.

[0067] The diffusion direction is from the interior of the highlighted display area 1 towards the first pixel 1-1, such as... Figure 6 As shown, taking the first pixel 1-1 in the middle of the lower part of the highlighted display area 1 as an example, its diffusion direction is as shown by the white arrow in the figure, that is, from the 9.1V pixel to the 9.3V pixel.

[0068] There are multiple second pixels 2-1 adjacent to the first pixel 1-1. If all the second pixels 2-1 are adjusted, the multiple adjusted second pixels 2-1 will tend to form a regular ring structure, which cannot achieve the effect of blurring the boundary. In this embodiment, only the second pixels 2-1 along the diffusion direction are adjusted, which can make the multiple adjusted second pixels 2-1 arranged irregularly, and the boundary is not clear visually, thus improving the afterimage phenomenon. In addition, setting the first voltage to be less than the original voltage of the first pixel 1-1 and greater than the original voltage of the adjacent second pixels 2-1 can fade the boundary of the original highlighted display area 1, which also makes the visual afterimage boundary blurry and improves the afterimage phenomenon.

[0069] In some embodiments, adjusting the original voltage of the second pixel 2-1 along the diffusion direction of the first pixel 1-1 to a first voltage includes:

[0070] S2201. Along the diffusion direction of the first pixel 1-1, adjust the original voltage of at least two second pixels 2-1 that are closest to the first pixel 1-1 to a first voltage, so that the original voltage of the first pixel 1-1 and the first voltage of the at least two second pixels 2-1 decrease along the diffusion direction.

[0071] The decreasing relationship can be, for example, an arithmetic progression or a geometric progression; there is no specific limitation. Figure 6 As shown, along the diffusion direction of the first pixel 1-1, the original voltages of the two second pixels 2-1 closest to the first pixel 1-1 are adjusted to the first voltage, and the original voltage of the first pixel 1-1 and the first voltages of the two second pixels 2-1 are made to decrease along the diffusion direction. In this way, the voltage of the pixel gradually weakens from the inside to the outside of the bright display area 1, which can effectively fade the boundary of the original bright display area 1 visually and improve the afterimage phenomenon.

[0072] In some embodiments, the number of second pixels 2-1 corresponding to two adjacent first pixels 1-1 that adjust the original voltage is different.

[0073] like Figure 11As shown, the highlight display area 1 is a 4*3 rectangle. At the top of the highlight display area 1, there are two adjacent first pixels 1-1 with a voltage of 9.3V. When adjusting the second pixel 2-1 corresponding to the first pixel 1-1, the number of second pixels 2-1 adjusted for the two first pixels 1-1 is different. This can avoid the edges from becoming too regular when forming a new set of highlight pixels 3, and further improve the afterimage phenomenon.

[0074] In some embodiments, the method for improving display panel image retention further includes:

[0075] S3. Adjust the original voltage of the pixels in the high-brightness display area 1 to a third voltage according to a preset frequency. The third voltage is less than the original voltage of the corresponding pixel.

[0076] The preset frequency can be a display frame interval of one pixel. The number of display frames can be odd or even, and there is no specific limitation.

[0077] like Figure 7 and Figure 8 As shown, by intermittently reducing the pixel voltage of the high-brightness display area 1, on the one hand, the user can see the display screen without reduced voltage by taking advantage of the persistence of vision in the human eye, without affecting the viewing experience. Moreover, the alternating brightness setting will make the high-brightness effect more obvious and improve the user experience. On the other hand, by reducing the voltage, the threshold voltage drift recovery time of the TFT in the high-brightness display area 1 is reserved, thereby improving the afterimage phenomenon. At the same time, reducing the voltage can reduce the degradation rate of the light-emitting device material and improve its service life.

[0078] In some embodiments, the preset frequency can be an interval of multiple display frames, such as an interval of two display frames for voltage adjustment. The preset frequency is at most an interval of 10 display frames to avoid excessively long intervals that could cause visual persistence of the reduced voltage image and reduce user experience.

[0079] In some embodiments, a third voltage adjustment can be performed on two to three consecutive display frames to allow more time for drift recovery, further reduce the degradation rate of the light-emitting device material, and improve image retention.

[0080] In some embodiments, the third voltage is 0, or is scaled down proportionally to the original voltage of the corresponding pixel.

[0081] like Figure 8 As shown, the third voltage is 0, which can effectively improve the afterimage and allow the threshold voltage to be fully recovered; as Figure 7 As shown, the third voltage can be scaled down proportionally to the original voltage of the corresponding pixel. For example, all pixels in the high-brightness display area 1 can be scaled down by 50% of the original voltage. This restores the drift while ensuring a certain level of display brightness and improving the display effect.

[0082] In some embodiments, the aforementioned high-brightness display area 1 can be down-processed at a first preset frequency, and the aforementioned edge blurring can be performed at a second preset frequency. For example, the high-brightness display area 1 can be down-processed for pixels in odd-numbered frames, and the edge blurring can be performed for pixels in even-numbered frames. This can improve the afterimage phenomenon in a coordinated manner.

[0083] In some embodiments, the original voltages of the pixels other than the first pixel 1-1 in the bright display area 1 are adjusted to the third voltage at a preset frequency. This allows for edge blurring of pixels in consecutive frames. For example, the voltages of the first pixel 1-1 and the second pixel 2-1 in consecutive frames can be swapped. This ensures that the edge blurring is not interfered with and improves the image retention phenomenon more efficiently.

[0084] Based on the same inventive concept, corresponding to any of the methods in the above embodiments, this application also provides an apparatus for improving display panel image retention, see reference. Figure 12 The system includes: an acquisition module 121, configured to acquire a bright display area 1 and a non-bright display area 2 of the display panel, wherein pixels located at the edge of the bright display area 1 are first pixels 1-1, and pixels close to the first pixels 1-1 and located within the non-bright display area 2 are second pixels 2-1; and a voltage adjustment module 122, configured to adjust the original voltage of a portion of the second pixels 2-1 to a first voltage based on the original voltage of the first pixels 1-1, wherein the second pixels 2-1 subjected to voltage adjustment are arranged in a dispersed or irregular manner.

[0085] In some embodiments, the acquisition module 121 is further configured to acquire the original voltage of each pixel in the display panel; and determine the high-brightness display area 1 and the non-high-brightness display area 2 of the display panel according to a preset high-brightness voltage threshold and the original voltage.

[0086] In some embodiments, the voltage regulation module 122 is further configured to swap the original voltage of the first pixel 1-1 with a portion of the original voltage of the second pixel 2-1, such that the voltage of the second pixel 2-1 is a first voltage and the voltage of the first pixel 1-1 is a second voltage, and the second pixels 2-1 that have swapped voltages are spaced apart.

[0087] In some embodiments, the voltage regulating module 122 is further configured to swap the voltage of a portion of the first pixel 1-1 with the second pixel 2-1 adjacent to the first pixel 1-1, such that the first pixel 1-1 that has not undergone voltage swapping is spaced apart from the second pixel 2-1 that has undergone voltage swapping.

[0088] In some embodiments, the voltage regulating module 122 is further configured to swap the voltage of all the first pixels 1-1 with the second pixels 2-1 located in the diffusion direction of the first pixels 1-1.

[0089] In some embodiments, the voltage regulating module 122 is further configured to adjust the original voltage of the second pixel 2-1 along the diffusion direction of the first pixel 1-1 to a first voltage, wherein the first voltage of the second pixel 2-1 is less than the original voltage of the first pixel 1-1 and greater than the original voltage of other second pixels 2-1 adjacent to the second pixel 2-1.

[0090] In some embodiments, the voltage regulating module 122 is further configured to adjust the original voltage of at least two second pixels 2-1 closest to the first pixel 1-1 to a first voltage along the diffusion direction of the first pixel 1-1, such that the original voltage of the first pixel 1-1 and the first voltage of the at least two second pixels 2-1 decrease along the diffusion direction.

[0091] In some embodiments, the apparatus for improving display panel image retention further includes a step-down module configured to adjust the original voltage of the pixels in the high-brightness display area 1 to a third voltage at a preset frequency, the third voltage being less than the original voltage of the corresponding pixel.

[0093] Based on the same inventive concept, corresponding to the methods of any of the above embodiments, this application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method for improving display panel afterimages as described in any of the above embodiments.
