Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display method, apparatus, terminal and storage medium. Background Technology

[0002] Typically, a terminal is equipped with a display device to show content to the user.

[0003] In related technologies, many display devices used in terminals suffer from slow response times. For example, Liquid Crystal Displays (LCDs), especially the increasingly popular negative LCDs, are a prime example. Specifically, in an LCD, one pixel can correspond to multiple liquid crystals. When the color displayed by that pixel needs to be changed to a target color, voltage can be used to control the flipping of these liquid crystals, thus changing the pixel's color from the current color to the target color. Here, the time from the application of voltage to the display pixel until the pixel's color reaches the target color can be understood as the response time. Furthermore, the greater the contrast between the current color and the target color of the display pixel, the slower the response time. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a display method, apparatus, terminal and storage medium.

By reducing the contrast between the color of the display object in the first layer and the background color, the response speed of the display device's display pixels changing from the color of the display object's edge to the background color, or vice versa, is accelerated. This avoids the problem of flickering perceived by the human eye due to the slow response speed of the display device.

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0065] Figure 1A This is a block diagram illustrating a display method according to an exemplary embodiment. The execution subject of the display method provided in this embodiment can be a terminal, such as a mobile phone, tablet computer, etc. Figure 1A As shown, the method in this embodiment may include the following steps:

[0066] In step 101, when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than a preset contrast, the contrast between the color of the edge of the display object in the first layer and the background color is reduced before the image to be displayed is displayed, and the processed image to be displayed is obtained.

[0067] In this step, the image to be displayed can be composited from multiple layers, including a first layer. The first layer can be any one of these layers. The background color of the image to be displayed can be the color of the first layer, or the color of any other layer. Contrast refers to the degree of contrast between colors. Higher contrast means greater color contrast; lower contrast means less color contrast. Optionally, the displayed object can be text, graphic, etc.

[0068] When the contrast between the color of the displayed object in the first layer of the image and the background color of the image is greater than a preset contrast, it indicates that the contrast between the color of the displayed object in the first layer and the background color is too high. When the contrast between the color of the displayed object in the first layer of the image and the background color of the image is less than or equal to the preset contrast, it indicates that the contrast between the color of the displayed object in the first layer and the background color is not too high.

[0069] Furthermore, there are currently scenarios where the color of the display pixels on a display device changes from the edge color of the displayed object to the background color, or vice versa. For example, in a scenario where a page is used to display an image, the content of the page can change continuously as the user scrolls (left / right or up / down). Suppose the page displays three text segments A, B, and C from top to bottom; when the user scrolls up, it displays three more text segments B, C, and D from top to bottom. When the contrast between the color of the displayed object and the background color in the first layer is too high, the response speed of the display pixel's color changing from the edge color of the displayed object to the background color, or vice versa, is slow. Therefore, when the color of the display pixel needs to change between the edge color of the displayed object and the background color, the slow response speed of the display device can cause a flickering effect perceived by the human eye.

[0070] Here, by reducing the contrast between the color of the display object edge and the background color in the first layer before displaying the image to be displayed, the processed image to be displayed is obtained. This speeds up the response speed of the display pixel color changing from the color of the display object edge to the background color, or from the background color to the color of the display object edge, thereby avoiding the problem of flickering perceived by the human eye due to the slow response speed of the display device.

[0071] Furthermore, for applications (Apps) and web pages that provide text reading functionality, the displayed object can be a text object. When a user scrolls the page, the color of the displayed pixels needs to frequently change between the color of the displayed object's edge and the background color. When the contrast between the color of the displayed object's edge and the background color is too high, text ghosting can occur due to the slow response speed of the display device, resulting in a poor user experience and even dizziness. By reducing the contrast between the color of the displayed object's edge and the background color, when the color of the displayed pixels frequently changes between the color of the displayed object's edge and the background color, the text ghosting problem can be avoided, thus improving the user experience.

[0072] Optionally, the contrast between the color of the displayed object and the background color, except for the area before the edge of the displayed object, can remain unchanged to ensure display clarity.

[0073] In step 102, the processed image to be displayed is shown.

[0074] In this step, the processed image to be displayed is shown to the user. Specifically, the image obtained after processing in step 101 can be displayed using a display device. This display device can be a display device with a slow response time, such as a liquid crystal display (LCD). Assuming the displayed object is text, its color is black, and the background color is white, the display effect of displaying the processed image can be as follows: Figure 1B As shown. Figure 1B The edges of the displayed objects are gray, and the contrast between the edges of the displayed objects and the background color is less than the contrast between black and the background color.

[0075] The display method provided in this embodiment first reduces the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed when the contrast is greater than a preset contrast. This results in a processed image to be displayed, which is then displayed. By reducing the contrast between the color of the display object in the first layer and the background color, the response speed of the display device's display pixels changing from the color of the display object's edge to the background color, or vice versa, is accelerated. This avoids the problem of flickering perceived by the human eye due to the slow response speed of the display device.

[0076] Figure 2 This is a block diagram illustrating a display method according to another exemplary embodiment. (Refer to...) Figure 2 The method provided in this embodiment is Figure 1A Based on the method shown, this paper mainly describes an optional implementation method for obtaining a processed image by reducing the contrast between the edge color of the display object in the first layer and the background color before displaying the image, when the background color of the image to be displayed is the background color of the first layer. Figure 2 As shown, the method in this embodiment may include:

[0077] In step 201, when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than a preset contrast, before merging the first layer and the second layer to obtain the image to be displayed, the contrast between the color of the edge of the display object in the target layer and the background color of the target layer is reduced, and the target layer is the first layer, thus obtaining the processed target layer.

[0078] In this step, the image to be displayed can be composited from multiple layers, including a first layer and a second layer. The first layer can be any layer whose background color is the background color of the image to be displayed, and the second layer can be any layer other than the first layer. There can be one or more second layers. Specifically, when the background color of the image to be displayed is the background color of the first layer, the contrast between the edge color of the displayed object in the first layer and the background color of the first layer can be reduced.

[0079] It should be noted that this disclosure does not limit the specific method for reducing the contrast between the edge color of the displayed object in the first layer and the background color of the first layer. Optionally, the pixel value of the first pixel in the image corresponding to the first layer can be interpolated with the pixel value of the second pixel adjacent to the first pixel to obtain the pixel value of the first pixel. The first pixel traverses all pixels in the image corresponding to the target display image. Here, the image corresponding to the first layer can be understood as an image of a single layer (i.e., a single first layer), rather than an image composed of multiple layers. The second pixel adjacent to the first pixel may specifically include: a pixel directly above the first pixel adjacent to the first pixel, and an element directly below the first pixel adjacent to the first pixel. Alternatively, the second pixel adjacent to the first pixel may specifically include: a pixel directly above the first pixel adjacent to the first pixel, an element directly below the first pixel adjacent to the first pixel, a pixel directly to the left of the first pixel adjacent to the first pixel, and an element directly to the right of the first pixel adjacent to the first pixel.

[0080] It should be noted that this disclosure does not limit the specific method of interpolation. Optionally, interpolation can be performed according to preset weights. For example, assuming that the weight of the pixel value of the first pixel a is w1, and the second pixels adjacent to the first pixel are a1, a2, a3, and a4, and the weight of the second pixel is w2, then the pixel value of the first pixel a obtained by interpolation can be equal to (a×w1+(a1+a2+a3+a4)×w2) / (w1+4×w2).

[0081] In step 202, the processed target layer and the second layer are merged to obtain the processed image to be displayed.

[0082] In this step, specifically, the second layer and the processed first layer can be merged to obtain the processed image to be displayed. It should be noted that the specific method for merging layers to obtain the image can be found in existing implementations and will not be elaborated upon here.

[0083] In step 203, the processed image to be displayed is shown.

[0084] It should be noted that step 203 is similar to step 102, and will not be described again here.

[0085] The display method provided in this embodiment first reduces the contrast between the color of the display object edge and the background color of the first layer of the image to be displayed when the contrast is greater than a preset contrast. This results in a processed first layer. Then, the processed first layer and the second layer are merged to obtain a processed image to be displayed. Finally, the processed image to be displayed is displayed. This method reduces the contrast between the color of the display object edge and the background color of the first layer, thus accelerating the response speed of the display device's display pixels from the color of the display object edge to the background color, or vice versa. This avoids the problem of flickering perceived by the human eye due to the slow response speed of the display device.

[0086] Figure 3 This is a block diagram illustrating a display method according to yet another exemplary embodiment. (Refer to...) Figure 3 The method provided in this embodiment is Figure 1A Based on the method shown, this paper mainly describes an optional implementation method for obtaining a processed image by reducing the contrast between the edge color of the first layer's display object and the background color before displaying the image when the background color of the image to be displayed is the color of the third layer. For example... Figure 3 As shown, the method in this embodiment may include:

[0087] In step 301, when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than a preset contrast, before merging the first layer, the second layer and the third layer to obtain the image to be displayed, the first layer and the third layer are merged to obtain the target layer.

[0088] In this step, the image to be displayed can be synthesized from multiple layers, including a first layer, a second layer, and a third layer. The third layer can be any layer whose background color is the background color of the image to be displayed. The first layer can be any layer other than the third layer, and the second layer can be any layer other than the first and third layers. There can be one or more second layers. Specifically, when the background color of the image to be displayed is the background color of the third layer, the first and third layers can be merged to obtain the target layer.

[0089] In step 302, the contrast between the color of the display object edge of the target layer and the background color of the target layer is reduced to obtain the processed target layer.

[0090] In this step, it should be noted that the specific method for reducing the contrast between the edge color of the target layer's display object and the background color of the target layer is not limited in this disclosure. Optionally, the pixel value of the first pixel in the image corresponding to the target layer can be interpolated with the pixel value of the second pixel adjacent to the first pixel to obtain the pixel value of the first pixel. The first pixel iterates through all pixels in the image corresponding to the target display image. Here, the image corresponding to the target layer can be understood as an image of a single layer (i.e., a single target layer), rather than an image composed of multiple layers. The second pixel adjacent to the first pixel may specifically include: a pixel directly above the first pixel adjacent to the first pixel, and an element directly below the first pixel adjacent to the first pixel. Alternatively, the second pixel adjacent to the first pixel may specifically include: a pixel directly above the first pixel adjacent to the first pixel, an element directly below the first pixel adjacent to the first pixel, a pixel directly to the left of the first pixel adjacent to the first pixel, and an element directly to the right of the first pixel adjacent to the first pixel.

[0091] It should be noted that this disclosure does not impose any restrictions on the specific interpolation method.

[0092] In step 303, the processed target layer and the second layer are merged to obtain the processed image to be displayed.

[0093] In this step, specifically, the second layer and the processed target layer can be merged to obtain the processed image to be displayed. It should be noted that the specific method for merging layers to obtain the image can be found in existing implementations and will not be elaborated upon here.

[0094] In step 304, the processed image to be displayed is shown.

[0095] It should be noted that step 304 is similar to step 102, and will not be described again here.

[0096] The display method provided in this embodiment first merges the first and third layers to obtain a target layer when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than a preset contrast. Then, it reduces the contrast between the color of the edge of the display object in the target layer and the background color of the target layer to obtain a processed target layer. Then, it merges the processed target layer and the second layer to obtain a processed image to be displayed. Finally, it displays the processed image to be displayed. By reducing the contrast between the color of the edge of the display object in the first layer and the background color, the response speed of the display device's display pixels from the color of the display object edge to the background color, or from the background color to the color of the display object edge, is accelerated. This avoids the problem of flickering perceived by the human eye due to the slow response speed of the display device.

[0097] Figure 4 This is a block diagram illustrating a display method according to yet another exemplary embodiment. (Refer to...) Figure 4 The method provided in this embodiment is Figure 1A Based on the method shown, this paper mainly describes an optional triggering condition for reducing the contrast between the edge color of the displayed object in the first layer and the background color. For example... Figure 4 As shown, the method in this embodiment may include:

[0098] In step 401, when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than the preset contrast, it is determined whether the display object in the first layer meets the target condition before displaying the image to be displayed.

[0099] In this step, the target conditions include: the number of displayed objects in the first layer is greater than or equal to a quantity threshold, and / or, the area proportion of displayed objects in the first layer is greater than or equal to a proportion threshold. The proportion threshold can specifically be area size or area proportion. The fact that the displayed objects in the first layer meet the target conditions can be understood as a further condition that can be satisfied by reducing the contrast between the color of the displayed objects' edges and the background color of the image to be displayed, in scenarios where the contrast between the colors of the displayed objects' colors in the first layer and the background color of the image to be displayed is greater than a preset contrast.

[0100] When the displayed objects in the first layer meet the target condition, it means that when the contrast between the color of the displayed object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than the preset contrast, the difference in contrast between the color of the displayed object and the background color of the image to be displayed will bring a poor user experience. Therefore, the contrast between the color of the edge of the displayed object in the first layer and the background color can be further reduced. When the displayed objects in the first layer do not meet the target condition, it means that when the contrast between the color of the displayed object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than the preset contrast, the difference in contrast between the color of the displayed object and the background color of the image to be displayed will not bring a poor user experience. Therefore, the contrast between the color of the edge of the displayed object in the first layer and the background color can remain unchanged.

[0101] Optionally, when there is only one object displayed in the first layer, the area ratio of the displayed object can be the ratio of the area of ​​the region where the displayed object is located to the total area of ​​the first layer. When there are multiple objects displayed in the first layer, the area ratio of the displayed objects can be the ratio of the sum of the areas of the regions where the multiple displayed objects are located to the total area of ​​the first layer.

[0102] It should be noted that the quantity threshold and the percentage threshold can be preset thresholds or thresholds obtained through other means, such as those set by the user. This disclosure does not limit them.

[0103] If the displayed objects in the first layer meet the target conditions, proceed to step 402; if the displayed objects in the first layer do not meet the target conditions, proceed to step 404.

[0104] In step 402, the contrast between the color of the display object edge and the background color in the first layer is reduced to obtain the processed image to be displayed.

[0105] It should be noted that the specific method for reducing the contrast between the edge color of the displayed object in the first layer and the background color in this step to obtain the processed image to be displayed can be found in the relevant description of the foregoing embodiments, and will not be repeated here. After step 402 is completed, step 403 can be further executed.

[0106] In step 403, the processed image to be displayed is displayed.

[0107] It should be noted that step 403 is similar to step 102, and will not be described again here.

[0108] In step 404, the image to be displayed is displayed.

[0109] In this step, the image to be displayed, which has not undergone the processing in step 402 (reducing the contrast between the color of the display object's edge and the background color), is shown to the user. Specifically, the image to be displayed can be displayed through a display device. This display device can be a display device with a slow response time, such as a liquid crystal display (LCD).

[0110] The display method provided in this embodiment first determines whether the display object in the first layer meets the target condition when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than a preset contrast. If the display object in the first layer meets the target condition, the contrast between the edge color of the display object in the first layer and the background color is reduced to obtain the processed image to be displayed. Then the processed image to be displayed is displayed. If the display object in the first layer does not meet the target condition, the image to be displayed is displayed. This achieves targeted processing of contrast differences that would bring a poor user experience when the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than the preset contrast.

[0111] The following are embodiments of the apparatus disclosed herein, which can be used to execute embodiments of the method disclosed herein. For details not disclosed in the apparatus embodiments of this disclosure, please refer to the embodiments of the method disclosed herein.

[0112] Figure 5 This is a block diagram illustrating a display device according to an exemplary embodiment. The device can be implemented as part or all of a terminal through software, hardware, or a combination of both. (Refer to...) Figure 5 The device includes a contrast module 51 and a first display module 52. Wherein,

[0113] The contrast module 51 is configured to reduce the contrast between the color of the display object of the first layer of the image to be displayed and the background color of the image to be displayed before displaying the image, when the contrast between the color of the display object of the first layer and the background color of the image to be displayed is greater than the preset contrast, so as to obtain the processed image to be displayed.

[0114] The first display module 52 is configured to display the processed image to be displayed.

[0115] Optionally, the display object is a text object.

[0116] In summary, the display device provided in this embodiment reduces the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed when the contrast between the two colors is greater than a preset contrast. This results in a processed image to be displayed, which is then displayed by the first display module. By reducing the contrast between the color of the display object in the first layer and the background color, the response speed of the display pixel's color changes from the color of the display object's edge to the background color, or vice versa, thus avoiding the problem of flickering perceived by the human eye due to a slow response speed of the display device. When the contrast between the color of the display object in the first layer of the image to be displayed and the background color of the image to be displayed is greater than the preset contrast, the contrast between the color of the edge of the display object in the first layer and the background color is first reduced to obtain the processed image to be displayed. Then the processed image to be displayed is displayed. By reducing the contrast between the color of the edge of the display object in the first layer and the background color, the response speed of the display device's display pixels from the color of the display object edge to the background color, or from the background color to the color of the display object edge, is accelerated. This avoids the problem of flickering perceived by the human eye due to the slow response speed of the display device.
