Abstract
Description
Technical Field
[0001] The present invention relates to the field of display technology, and in particular to a display method, device, equipment and storage medium. Background Art
[0002] With the continuous advancement of display technology, the resolution and display quality of display devices (such as LCDs, OLED displays, etc.) have been significantly improved. In order to achieve higher resolution at the smallest possible physical size, the industry has begun to adopt sub-pixel rendering (SPR) technology. Different from the traditional rendering method based on whole pixels, SPR technology will further subdivide the light-emitting unit of a pixel into independent sub-pixels (such as red, green, and blue sub-pixels), and achieve resolution and fineness that exceeds the original number of pixels by flexibly combining and adjusting the light-emitting brightness of sub-pixels.
[0003] However, SPR faces a key problem in its application: since the display often needs to "borrow" sub-pixels from adjacent pixels to achieve fine adjustment of color and brightness, pixels in the edge area often cannot borrow colors from areas beyond the screen boundary. Due to the lack of complete auxiliary light from adjacent areas, these pixels at the edge of the display often have problems such as chromaticity shift and edge aliasing during the rendering process. This not only affects the edge smoothness and color consistency of the entire image, but also weakens the advantages of SPR technology in improving resolution and image quality.
[0004] Traditional solutions often assign special weights to edge pixels or adjust them individually in order to maintain the visual effect as much as possible without the assistance of some sub-pixels. However, such methods are often difficult to achieve ideal display effects due to complex adjustment algorithms, cumbersome weight settings, and unstable performance in different content scenarios.
[0005] Therefore, there is an urgent need for a more efficient, more intelligent and SPR-compatible edge pixel display control method to ensure high resolution and high image quality of the display device in the absence of complete sub-pixel "borrowing", overcome the jagged edges, color deviation and distortion problems in the edge areas, and achieve a smoother, more accurate and comfortable visual experience.

[0029] See also Figure 1 , is a display method provided in an embodiment of the present application, which optimizes the display effect by adjusting the display parameters of edge pixels to reduce visual impairments caused by excessive brightness, such as jaggedness and color shift. The method provided in this embodiment includes: Step S101: define an edge pixel area.
[0030] The image display device defines an edge area according to the image content and display area. This edge area is usually the four border parts of the image, such as the top, bottom, left and right pixels. In particular, these areas are easily affected by factors such as image resolution and display device characteristics. It is easy to have jagged or uneven edges. Specifically, the system defines the four edges of the image, such as the top, bottom, left and right, and possible corner parts as edge pixel areas. The definition of the edge pixel area can be appropriately adjusted according to the requirements of the display device, screen resolution, etc. For example, the upper 20 pixel rows, the lower 20 pixel rows, and the left and right 10 pixel rows of the image are set as the edge area.
[0031] Step S102: Obtain display parameters of edge pixels.
[0032] The display parameters usually include the color information, brightness value, color saturation, etc. of the pixel. For example, the system may obtain the RGB value (the value of red, green, and blue) of the edge pixel, and the RGB value of each pixel is used for subsequent brightness calculation.
[0033] Step S103: Calculate the actual brightness value of the edge pixel.
[0034] Among them, according to the acquired display parameters, the system will calculate the actual brightness value of each edge pixel. The brightness value is usually obtained by weighted calculation of the three components (red, green, and blue) in the RGB color model. Specifically, the calculation formula of the brightness value is as follows:
[0035] Among them, R, G, and B are the red, green, and blue component values of the edge pixel respectively. The brightness value reflects the brightness of the image.
[0036] Step S104: determine whether the actual brightness value exceeds a preset brightness threshold.
[0037] After the actual brightness value of the edge pixel is calculated, the actual brightness value of each edge pixel is compared with a preset brightness threshold.
[0038] The setting of the brightness threshold depends on different display environments, application scenarios and display requirements. The brightness threshold can be dynamically adjusted based on the following factors: Brightness range of displayed content: If a bright image or background color is being displayed on the screen, the threshold should adapt to this brightness variation and is usually set based on the global brightness of the screen.
[0039] Brightness characteristics of edge areas: In edge areas, due to uneven distribution of light sources, the brightness threshold may be lower to avoid display anomalies caused by ambient light or color difference. The threshold can be set to a more conservative value to ensure timely adjustment in high-brightness scenes.
[0040] Screen type and display technology: For different types of screens such as OLED and LCD, the setting of brightness threshold may also be different. For example, in OLED screens, due to the self-luminous characteristics, its brightness adjustment may require different processing.
[0041] Step S105: If the brightness value exceeds a preset brightness threshold, adjust the display parameters.
[0042] In actual display processing, in order to prevent the loss of specific border images due to brightness adjustment, this technical solution introduces a brightness threshold determination mechanism. When it is detected that the brightness of pixels close to the edge is lower than a preset threshold (for example, a reasonable range between 32 and 128), the low-brightness pixel can be identified as a border area pixel that needs to be protected, rather than simply clearing its brightness to zero. Through this threshold setting, the integrity and display quality of the border image can be ensured while reducing the edge brightness, thereby improving the visual effect while meeting the protection requirements of specific image content.
[0043] Step S106: Display the image.
[0044] After adjusting the display parameters of edge pixels, the system will eventually generate processed display data and output the image using a display device. At this point, the display effect of the edge area has been optimized, and pixels with too high or too low brightness have been adjusted to a suitable range, avoiding problems such as overexposure and color shift, and ensuring image clarity and natural transition.
[0045] The image display method of this embodiment can effectively avoid the jaggedness, edge overbrightness or color shift problems that occur during the display process. By accurately controlling the display parameters of edge pixels, especially the brightness value and contrast, the image display quality is significantly improved, so that the display device can better handle the display requirements of high contrast and complex image content.
[0046] For further information, see Figure 2 The method comprises: Step S201: Obtain display parameters of edge pixels.
[0047] Step S202: Calculate the actual brightness value of the edge pixel.
[0048] Step S203: determining whether the actual brightness value of the edge pixel exceeds a preset brightness threshold.
[0049] The actual brightness value of each edge pixel is compared with a preset brightness threshold value. If the actual brightness value exceeds the threshold value, it indicates that the brightness of the edge pixel may be too high or too low and needs to be adjusted.
[0050] Step S204: Mark edge pixels that exceed a brightness threshold.
[0051] Among them, for the target pixel whose brightness value exceeds the preset brightness threshold, it is marked. A mark bit (such as "mark") can be set to indicate that the pixel is a highlight pixel, usually using a Boolean value or integer (such as 1 for marking and 0 for not marking) to record.
[0052] Step S205: at a preset detection time point, detecting whether all edge pixels are marked.
[0053] Wherein: at a preset detection time point (for example, before each image frame refresh or during a regular check), it is detected whether all edge pixels in the edge area have been marked.
[0054] If at this moment, all edge pixels have been marked as exceeding the brightness threshold and need to be adjusted, then the adjustment step is continued.
[0055] Step S206: Adjust display parameters.
[0056] By marking and timing detection, it is ensured that each pixel that needs to be adjusted is processed in a timely manner to avoid obvious jaggedness, color cast or other adverse visual effects during image output, thereby improving image quality and visual experience.
[0057] Furthermore, in the edge area, if the actual brightness value of one of the edge pixels exceeds the brightness threshold, the edge pixel is marked. At a preset detection time point, it is detected whether all edge pixels adjacent to the marked edge pixel are marked. If N consecutive edge pixels are marked, the display parameters of the N edge pixels are adjusted.
[0058] Based on the same inventive concept as the above embodiments, the above embodiments are described in detail below through a specific application scenario. Step S301: define the left edge of the display area as the edge area, specifically the leftmost continuous area of each line of the display area Pixel.
[0059] Suppose the pixels in each row of the display area are numbered as (in is the row number, is the number of pixels in the left edge area). The edge area is the leftmost 1st to 2nd pixels, that is:
[0060] in, Indicates the number of rows currently being processed.
[0061] Step S302: For each target pixel (in is the row number, j is the column number, and 1) Determine the pixel Is it greater than the preset brightness threshold? .Right now: like ,but For highlight pixels If each line from arrive The pixel values satisfy , then the target pixel area of this row is considered to be a highlight area.
[0062] Step S303: At a preset detection time point, when the pixel value of each pixel in the target pixel area is detected Both are greater than the threshold Specifically, set a marking bit , a value of 1 indicates that the pixel is a highlight pixel, and a value of 0 indicates that the pixel is not a highlight pixel. That is:
[0063] If all pixels in the target pixel area , ,…, If all are 1, then all pixels in the target pixel area are considered to be highlight pixels.
[0064] Step S304: adjusting the display parameters of the edge pixels.
[0065] Step S305: output display data.
[0066] In a specific implementation, the adjusting the display parameter includes: adjusting the brightness input value of the edge pixel to zero.
[0067] Image display devices control the display effect of each pixel by receiving digital signals (such as RGB values). The brightness input value usually refers to the numerical value that controls the brightness of the pixel. For example, in the RGB color model, the brightness value of each channel of red, green, and blue is usually represented by a number from 0 to 255, where 0 represents the darkest (no brightness) and 255 represents the brightest (maximum brightness). In this solution, the brightness input value refers to the original input signal data used to display the brightness of the pixel.
[0068] Adjusting the brightness input value of edge pixels to zero means completely suppressing the brightness intensity of these over-bright edge pixels so that they no longer affect the final displayed image effect.
[0069] For example, if the brightness input value of an edge pixel is 255 (maximum brightness), adjusting to zero means setting this value to 0, so that the pixel will no longer emit light on the display, thus avoiding overly bright areas in the image display.
[0070] Furthermore, the method comprises: Step S401: In a display area of a display device, pixels are divided into two types of edge pixels: first edge pixels and second edge pixels.
[0071] The first edge pixels include pixels in the four edge regions of the display device, namely, at least one of the first row of pixels, the last row of pixels, the first column of pixels, and the last column of pixels. The first edge pixels are located at the edge of the display region and are the pixels that are most directly in contact with the display boundary. They often require special processing to ensure a smooth and balanced display effect.
[0072] The second edge pixels are pixels adjacent to the first edge pixels. Specifically, the second edge pixels include pixels of a preset number of rows or a preset number of columns adjacent to the first edge pixels. By setting a preset range, the second edge pixels ensure that the pixels of the entire edge area can be effectively processed to avoid omission.
[0073] Step S402: at a preset detection time point, detecting whether N consecutive first edge pixels are marked.
[0074] The system checks N consecutive first edge pixels to determine whether the N first edge pixels have been marked according to whether their brightness exceeds the standard.
[0075] If all N consecutive first edge pixels have been marked (ie, all edge pixels to be processed have been identified), the next step is entered to continue processing the second edge pixels.
[0076] If there are first edge pixels that are not marked, this means that the actual brightness values of the first edge pixels are within the normal range and do not need to be adjusted, so they are normal and do not require further processing.
[0077] Step S403: At a preset detection time point, whether all second edge pixels adjacent to the marked first edge pixel are marked.
[0078] The system will check the second edge pixels adjacent to the marked first edge pixels to determine whether these pixels have been marked, and the marking conditions are the same as those for the first edge pixels.
[0079] If the actual brightness value of the second edge pixel exceeds the preset brightness threshold, the actual pixel point of the second edge pixel is marked as a "highlight pixel". This process can be completed by setting a flag bit, such as setting a Boolean value (such as 1 for highlight and 0 for non-highlight) to record whether the pixel point is highlighted.
[0080] Step S404: If all the second edge pixels adjacent to the marked first edge pixel are marked, proceed to step S405; if not, proceed to step S406.
[0081] Step S405: adjusting the brightness input value of the marked first edge pixel to zero.
[0082] Step S406: output display data.
[0083] In the above embodiment, after the input data of the marked first edge pixel is reset to zero, the auxiliary light emitting effect of the adjacent second edge pixel makes the edge transition smoother, thus avoiding the abrupt contrast between the edge of the display device and the central area of the screen.
[0084] In addition, by setting the data of the highlighted pixels to zero, not only can the visual discomfort caused by the excessive brightness of the edge area be avoided, but also the pixels in the adjacent area can continue to provide light, thereby reducing the visual anomalies caused by excessive brightness differences. It is worth noting that the partial data lost in the first target pixel area will not have a significant impact on the display effect, but will help reduce visual defects in the display and improve the overall display quality.
[0085] See also Figure 4 Based on the same inventive concept as the above-mentioned embodiment, an embodiment of the present invention provides a display device, the display device comprising: Edge pixel detection module 110: obtains display parameters of edge pixels in a preset edge region in the display device. Edge pixels are usually located at the edge of an image or display region, or in regions where brightness changes dramatically in the display region. These pixels can be identified and extracted by an image processing algorithm (e.g., an edge detection algorithm).
[0086] Brightness calculation module 120: Brightness calculation module 120 calculates actual brightness values of edge pixels according to the display parameters.
[0087] The judgment module 130 judges the calculation result of the brightness calculation module 120 and determines which edge pixels need to be adjusted. If the actual brightness value of the edge pixel exceeds the set brightness threshold, the pixel is considered to be too bright and may need to be adjusted.
[0088] Display adjustment module 140: According to the result of the determination module 130, the display adjustment module 140 adjusts the edge pixels.
[0089] Furthermore, the display device further includes: The analysis module 210 is used to obtain and analyze the display information input to the display device and generate analysis data; The decision module 220 generates a calculation method according to the analysis data of the analysis module 210, and the brightness calculation module 120 performs brightness calculation on the acquired edge pixels according to the calculation method.
[0090] In order to better understand the display device of the present invention, the following embodiment is described in detail. This embodiment explains how to use various modules to work together to optimize the display effect, especially the brightness calculation and adjustment when processing edge pixels.
[0091] In this embodiment, the display device is applied to a television with edge pixel optimization function. The display area of the television includes a plurality of pixel arrays, wherein the edge pixel is one of the key factors affecting the display quality.
[0092] In the display area, the display area is first scanned by the edge pixel detection module 110 to detect and obtain edge pixels in the display area.
[0093] The edge pixel detection module 110 not only obtains the position information of these edge pixels, but also extracts the display parameters related to these edge pixels, such as their color, brightness value, contrast, etc. These display parameters describe the visual characteristics of edge pixels and are the basis for subsequent optimization and processing.
[0094] The analysis module 210 receives the display parameters from the edge pixel detection module 110 and analyzes the parameters.
[0095] The decision module 220 determines whether to apply the processing before or after the display data is output based on the output result of the analysis module 210 .
[0096] If the analysis results show that certain display parameters (such as brightness, contrast, etc.) can be optimized before input display to avoid adverse effects during the display process, the decision module 220 will generate a processing method requiring image processing before input data.
[0097] If the analysis result shows that optimization is needed at a later stage of the display process to avoid poor display effects due to premature processing, the decision module 220 will choose to make adjustments after the display output.
[0098] According to the judgment of the decision module 220, the brightness calculation module 120 performs the corresponding calculation before or after the input data. If it is decided to process before input, the brightness calculation module 120 will calculate and adjust according to the display parameters of the input image; if it is decided to process after output, the brightness calculation module 120 will wait until the image rendering is completed before making adjustments to ensure that the display effect of edge pixels is optimal.
