Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display device and an image display method thereof.
Background
With the continuous progress of the manufacturing process, the number of Pixels (Pixels Per inc, abbreviated as PPI) contained in each Inch of the display panel is continuously increased, and the display panel with high PPI has higher resolution, finer display effect and better viewing experience. Although the PPI of the display panel is improved, the same image resolution is not required in all use scenarios, for example, in an application scenario, for an Organic Light-Emitting Diode (OLED) display panel, since the panel does not need a backlight, the power consumption of the panel mainly comes from the Light emission of pixels, and the pixel density of the OLED panel with high PPI is higher, so the screen power consumption is further increased. At this time, if the total power of the terminal is low and the display panel consumes too much power, other functions of the terminal cannot be guaranteed, and user experience is affected. In another application scenario, the display panel with high PPI may directly display the picture with low resolution sent by other devices, and at this time, the user may want to request the displayed picture to have higher resolution and better display effect, thereby also affecting the user experience and wasting the PPI resources.

To solve the problems in the prior art, embodiments of the present invention provide a display device and an image display method thereof, which can implement switching between multiple image resolutions.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, the present invention is further described with reference to the accompanying drawings and examples. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted. The words expressing the position and direction described in the present invention are illustrated in the accompanying drawings, but may be changed as required and still be within the scope of the present invention. The drawings of the present invention are for illustrative purposes only and do not represent true scale.
It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The description which follows is a preferred embodiment of the present application, but is made for the purpose of illustrating the general principles of the application and not for the purpose of limiting the scope of the application. The protection scope of the present application shall be subject to the definitions of the appended claims.
The following describes a display device and an image display method thereof according to an embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the image display method of the display device according to the embodiment of the present invention may specifically include the following steps:
s101, when a display mode switching instruction is received, determining a sub-pixel arrangement mode used for displaying in a current display mode, image data of each sub-pixel in an image and an image resolution of a target display mode;
s102, determining a sub-pixel arrangement mode for display in a target display mode according to the image resolution of the target display mode;
s103, determining the image data of each sub-pixel in the target display mode according to the sub-pixel arrangement mode for displaying in the current display mode, the image data of each sub-pixel in the current display mode and the sub-pixel arrangement mode for displaying in the target display mode;
and S104, displaying the image according to the determined image data.
First, the image display method provided by the embodiment of the present invention displays different image analyses by using the same display panel. After the display panel is manufactured, the arrangement mode of the sub-pixels of the display panel is determined, and then some sub-pixels emit light for display while other sub-pixels do not emit light all the time, so that the arrangement mode of the light-emitting sub-pixels is determined again, the image resolution is changed, and different display effects are achieved. Therefore, in the embodiment of the present invention, the arrangement of the sub-pixels for display is not equal to that of the display panel.
It can be understood that after the display panel is manufactured, the arrangement of the sub-pixels is fixed, and the pixel resolution is also fixed, corresponding to an image resolution when displaying an image. That is, in the embodiment of the present invention, a sub-pixel arrangement for displaying corresponds to an image resolution, and after determining which sub-pixel arrangement is used, the corresponding image resolution can be achieved when displaying the image. Based on the inventive concept, before the operation of switching the display modes is executed, the invention can predetermine a plurality of sub-pixel arrangement modes and corresponding image resolutions thereof aiming at the same display panel, and generate the mapping relation of pixels among different sub-pixel arrangement modes and the algorithm of image data conversion, so that the conversion of the image data can be carried out after the sub-pixel arrangement mode in the current display mode and the sub-pixel arrangement method in the target display mode are determined, thereby achieving the image resolution in the target display mode.
Specifically, in the embodiment of the present invention, when the display device receives a display mode switching instruction, it needs to first confirm whether to switch the display mode to a mode with a higher image resolution or a mode with a lower image resolution, and therefore, it needs to determine the arrangement of the sub-pixels for display in the current display mode, the image data, and the image resolution of the target display mode. The image resolution of the target display mode corresponds to the arrangement of at least one sub-pixel, so it is necessary to determine which sub-pixel arrangement is used for displaying. After the arrangement structure of the sub-pixels for display in the target display mode and the arrangement structure of the sub-pixels for display in the current display mode are determined, the currently acquired image data can be converted to determine the image data of each sub-pixel in the target display mode, so that the image data can be displayed after being output to an IC of a display panel, and the resolution of the displayed image is the image resolution of the target display mode.
The image display method provided by the embodiment of the invention can switch among a plurality of image resolutions according to the actual needs of users. For example, the display device may be a portable intelligent terminal, and when the total power of the terminal is low, the display mode may be switched to the display mode with low image resolution, and the number of sub-pixels used for displaying is reduced compared to the number of sub-pixels used for displaying before the switching, so that the display power consumption of the terminal is reduced, and the power consumption for displaying is reduced, so as to prevent the terminal from consuming power quickly and being unavailable for other applications. In another application scenario, if the user receives a picture of another device or the downloaded picture has a lower resolution and the user wants a finer display effect, the user can switch to a display mode with a higher image resolution based on the current display mode, thereby enhancing the picture display effect. The above is only illustrated by two application scenarios, and other application scenarios are not limited herein. In practical application, the display modes corresponding to various image resolutions can be graded, so that selection is more convenient, and user experience is further improved.
In a specific implementation, as described above, each image resolution may correspond to more than one sub-pixel arrangement for display, and for this case, in step S102, the determining, according to the image resolution of the target display mode, the sub-pixel arrangement for display in the target display mode may specifically include:
according to the image resolution of the target display mode, one sub-pixel arrangement mode is randomly selected from a plurality of sub-pixel arrangement modes corresponding to the image resolution and is used as the sub-pixel arrangement mode for displaying in the target display mode.
In practical applications, for the sub-pixel arrangement modes of the same pattern, if the arrangement order of the sub-pixels changes, the sub-pixels are still considered to belong to another sub-pixel arrangement mode, and therefore, there are many sub-pixel arrangement modes of the same image resolution, when the display mode is switched, the arrangement mode of the sub-pixels needs to be determined first, and then the image data can be further calculated, and for the above situation, one sub-pixel arrangement mode can be automatically selected by the background of the display device as the sub-pixel arrangement mode in the target display mode, so that the calculation of pixel mapping and image data conversion can be rapidly performed. As another embodiment, the arrangement of the corresponding plurality of sub-pixels may be sorted for one image analysis, so that the arrangement of the sub-pixels may be sequentially selected each time the image resolution is switched. The operation of selecting which sub-pixel arrangement mode can be realized by software programming, which is illustrative and not limiting for the specific embodiment.
Further, if the currently used display mode (image resolution) corresponds to the arrangement of the plurality of sub-pixels, the image display method provided by the embodiment of the present invention may further include the following steps:
and switching the sub-pixel arrangement mode used for displaying in the current display mode to another sub-pixel arrangement mode corresponding to the image resolution of the current display mode at every interval of a preset time period.
In a possible application scenario, users are accustomed to displaying with a certain image resolution, and in this case, the display device will use a sub-pixel arrangement for displaying for a long time, which will cause the use frequency of sub-pixels used for displaying for a long time to be inconsistent with that of non-luminous sub-pixels, and cause resource waste for sub-pixels left idle for a long time. In view of this, in the image display method provided in the embodiment of the invention, when the same image resolution corresponds to multiple sub-pixel arrangement manners, the sub-pixel arrangement manner is switched to another sub-pixel arrangement manner at the same image resolution every preset time period, so that the use frequencies of the sub-pixels are kept consistent as much as possible, and the display effect is not affected.
In a specific implementation, in step S103, determining the image data of each sub-pixel in the target display mode according to the arrangement of the sub-pixels for displaying in the current display mode, the image data of each sub-pixel in the current display mode, and the arrangement of the sub-pixels for displaying in the target display mode may include the following steps, which may be specifically shown in fig. 2:
s1031, determining a conversion algorithm of the image data switched from the current display mode to the target display mode according to the arrangement mode of the sub-pixels used for displaying in the current display mode and the arrangement mode of the sub-pixels used for displaying in the target display mode;
s1032, determining the image data of each sub-pixel in the target display mode according to the image data of each sub-pixel in the current display mode and the conversion algorithm.
As described above, the conversion algorithm of the image data when the display mode is switched needs to be determined according to the mapping relationship between the sub-pixels, and the mapping relationship between the sub-pixels depends on the arrangement method of the sub-pixels for display, so in the embodiment of the present invention, it is first determined which sub-pixel arrangement method is used at the target image resolution, and thus the algorithm for converting the image data between the sub-pixels in the current display mode and the sub-pixels in the target display mode is determined according to the arrangement method of the sub-pixels in the current display mode and the arrangement method of the sub-pixels in the target display mode. For example, two display panels having the sub-pixel arrangement modes of the structures shown in fig. 3 and 4 at the time of shipment can be used to display the same image, so that the image data conversion relationship between the two sub-pixel arrangement modes can be determined according to the image data of the two display panels. In addition, the conversion algorithm of the image data under different sub-pixel arrangement modes can be determined by adopting an experimental means or a specific mathematical model through a calculation mode, which is not limited herein. The conversion algorithm of the image data can be stored in the background of the display device in advance, and is extracted for conversion of the image data after the arrangement mode of the sub-pixels is determined.
In order to further optimize the display effect, after the above step S103 and before the step S104, the following steps may be further included:
and rendering the determined image data. After the converted image data is rendered, the converted image data is displayed by means of adjacent sub-pixel modes and an algorithm corresponding to the adjacent sub-pixel modes, so that the image resolution can be improved on the basis of the same sub-pixel arrangement structure.
The following will exemplify a sub-pixel arrangement that may be applied in the case of two different image resolutions before and after switching of the display mode:
in one implementation, as shown in fig. 3 and 4, two subpixel arrangements may be switched. The sub-pixel arrangement shown in fig. 3 may be the most common sub-pixel arrangement of a display panel, and specifically, the sub-pixels are arranged in a matrix and closely aligned; the arrangement rules of the sub-pixels in each row are the same, the sub-pixels in each row are repeatedly arranged according to a specific color sequence, and the colors of the sub-pixels in the same column are the same. In practical applications, the sub-pixels can be divided into red sub-pixels R, green sub-pixels G and blue sub-pixels B as shown in fig. 3, and the sub-pixels in each row can be repeatedly arranged according to the color sequence of R, G, B, the color of each column of sub-pixels is the same, and one red sub-pixel R, one green sub-pixel G and one blue sub-pixel B in the same row form one pixel P, as shown in fig. 3.
In comparison with the sub-pixel arrangement shown in fig. 3 and 4, in the sub-pixel arrangement shown in fig. 3, every two rows of sub-pixels are taken as a row group, and the extraction rules of the sub-pixels in the row group are the same; for the odd line group, extracting one sub-pixel every other sub-pixel for display by starting from the fourth sub-pixel in each line; for even-numbered row groups, one subpixel is extracted every other subpixel for display from the second subpixel in each row, and thus the subpixel arrangement shown in fig. 4 can be configured. In practical applications, referring to fig. 4, two sub-pixels are displayed as a sub-pixel unit, and a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit in two adjacent row groups form a delta-shaped or inverted-delta-shaped pixel P. The number of pixels shown in fig. 4 is less than the number of pixels shown in fig. 3.
Compared with the arrangement of the sub-pixels shown in fig. 3 and 4, the image resolutions of the two sub-pixels can be different by 8 times; in practical applications, the display mode corresponding to fig. 3 may be switched to the display mode corresponding to fig. 4 to reduce the image resolution, or the display mode shown in fig. 4 may be switched to the display mode corresponding to fig. 3 to improve the image resolution.
In another practical way, as shown in fig. 3 and fig. 5, there may be two sub-pixel arrangements switched with each other. The arrangement of the sub-pixels shown in fig. 3 can be referred to the above description, and will not be described herein.
In the sub-pixel arrangement shown in fig. 5, compared with the sub-pixel arrangement shown in fig. 3, the number of sub-pixels is reduced, and some sub-pixels can be extracted for displaying based on the sub-pixel arrangement shown in fig. 3, while the non-extracted sub-pixels are always in a dark state, specifically, in the sub-pixel arrangement shown in fig. 3, for odd rows of sub-pixels, one sub-pixel is extracted for displaying by starting with the first sub-pixel and extracting every three sub-pixels; for even-numbered rows of sub-pixels, one sub-pixel is extracted for display every other three sub-pixels starting with the third sub-pixel, and thus the sub-pixel arrangement shown in fig. 5 can be configured. In practical applications, referring to fig. 5, a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B in two adjacent groups of sub-pixels form a delta-shaped or inverted-delta-shaped pixel P. The number of pixels shown in fig. 5 is less than the number of pixels shown in fig. 3.
Compared with the arrangement of the sub-pixels shown in fig. 3 and 5, the image resolutions of the two sub-pixels can be different by 4 times; in practical applications, the display mode corresponding to fig. 3 may be switched to the display mode corresponding to fig. 5 to reduce the image resolution, or the display mode shown in fig. 5 may be switched to the display mode corresponding to fig. 3 to improve the image resolution.
In another practical way, as shown in fig. 6 and 7, there may be two sub-pixel arrangements that are switched with each other. The sub-pixel arrangement shown in fig. 6 may be another sub-pixel arrangement of the display panel, specifically, a plurality of sub-pixels are arranged in a plurality of rows, and sub-pixels in odd rows and sub-pixels in even rows are staggered by a distance of half a sub-pixel width in the row direction; the odd-row sub-pixels are arranged according to a first color sequence, and the even-row sub-pixels are arranged according to a second color sequence; each color sub-pixel is separated from an adjacent row of same color sub-pixels by a minimum distance of one sub-pixel width in the row direction. In practical applications, the sub-pixels may be divided into red, green and blue sub-pixels R, G and B as shown in fig. 6, and the sub-pixels are repeatedly arranged in color order of R, G, B for the odd-numbered rows and B, R, G for the even-numbered rows. As shown in fig. 6, a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B in two adjacent rows of sub-pixels form a delta-shaped or inverted delta-shaped pixel P.
