[0064] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0065] In one embodiment, as shown in Figure 1 A display device is provided. The display device in the embodiment can be a display screen applied in a VR (Virtual Reality) glasses or an AR (Augmented Reality) glasses. The display device can be a display screen based on an LCoS (Liquid Crystal On Silicon) technology, an OLED (Organic Light-Emitting Diode) technology, a MICRO LED (Micro Light Emitting Diode Display) technology, an LCD (Liquid Crystal Display) technology or a TFT-LCD (Thin film transistor liquid crystal display) technology.

[0066] The display device includes a display panel and a plurality of pixel driving circuits; each pixel driving circuit corresponds to each physical pixel in the display panel.

[0067] The physical pixel (PP), also referred to as an actual pixel, refers to a single pixel point physically existing on the display panel; in a spatial color type display device, one physical pixel is usually composed of three independent luminance sub-pixels of red, green and blue, and in a time sequence color display mode display device, one physical pixel is usually a single pixel point. For example, a common screen resolution is 1920x1080, in which 1920 is the screen width and 1080 is the screen height; for the same screen size, the more the number of physical pixels, the clearer the screen display effect, and the more dense the physical pixels, the clearer the display details. However, generally, the more the number of physical pixels, the larger the size of the display device.

[0068] In the embodiments of the present application, the direction towards the user is regarded as the top direction, and the display panel refers to the part of the display device above the pixel driving circuit. For example, the display panel based on the LCoS technology includes a glass substrate, a liquid crystal material and a common electrode layer; the display panel based on the OLED technology generally includes a cover glass, a color filter film, an encapsulation layer and a white emitter. The pixel driving circuit is generally integrated on a silicon-based backplane and corresponds to the physical pixel on the display panel one by one. The pixel driving circuit is used to receive the pixel information (generally a voltage signal or a current signal) corresponding to the image displayed by the physical pixel, and drive the physical pixel to display the image corresponding to the pixel information. In the embodiments of the present application, the pixel driving circuit includes a master electrode and a slave electrode.

[0069] The master electrode is used to receive the pixel information corresponding to the pixel driving circuit, and display the image corresponding to the pixel information in the pixel area of the display panel corresponding to the master electrode based on the pixel information.

[0070] The slave electrode is used to connect the master electrode or other master electrodes adjacent to the slave electrode in at least one display period, and display the image corresponding to the pixel information in the pixel area of the display panel corresponding to the slave electrode based on the pixel information of the master electrode.

[0071] In a first possible implementation manner of the embodiment, the pixel driving circuit includes one master electrode and one slave electrode, as shown in Figure 2 The display time of the display device for displaying one frame of image is divided into two display periods.

[0072] In the first display period, the slave electrode is connected to the master electrode in the same pixel driving circuit as the slave electrode, and in the second display period, the slave electrode is connected to the master electrode adjacent to the slave electrode and not in the same pixel driving circuit; thus, the slave electrode is connected to the left and right master electrodes respectively in the display time of one frame of image, that is, the pixel area corresponding to the slave electrode displays the pixel information corresponding to the left and right master electrodes respectively in the display time of one frame of image, and after superimposed display in time, it can be understood that the slave electrode displays the average of the pixel information corresponding to the two master electrodes in the display time of one frame of image. Thus, without increasing the physical pixels of the display device, the image display of the display device is higher in horizontal resolution and more delicate and soft in horizontal image display.

[0073] It should be noted that the slave electrode located at the right edge of the display panel shown in Figure 2 may be set not to be connected to any master electrode in the second display period, or may still be connected to the master electrode in the same pixel driving circuit as the slave electrode.

[0074] The above-mentioned display of pixel information corresponding to two different main electrodes by the electrode in two display cycles can be regarded as the average value of the pixel information corresponding to the two different main electrodes displayed by the electrode in the display time of one frame of image. The principle is the persistence of vision effect of human eyes. That is, when the human eye sees a rapidly changing image, a persistence of vision effect will occur, which means that the human eye will see multiple instantaneous images as a continuous picture.

[0075] In a second possible implementation of this embodiment, the pixel driving circuit includes a master electrode and a slave electrode, such as... Figure 3 As shown, the display time for one frame of an image is divided into two display cycles. In the first display cycle, the slave electrode connects to the main electrode located in the same pixel driving circuit as the slave electrode. In the second display cycle, the slave electrode connects to a main electrode adjacent to the slave electrode but not in the same pixel driving circuit. Thus, the slave electrode connects to both the upper and lower main electrodes within the display time of one frame. This means that the pixel area corresponding to the slave electrode displays the pixel information corresponding to both the upper and lower main electrodes within the display time of one frame. After being superimposed in time, it can be understood that the slave electrode displays the average of the pixel information corresponding to the two adjacent upper and lower main electrodes within the display time of one frame. In this way, without increasing the physical pixels of the display device, the image display achieves higher resolution in the vertical direction and a more delicate and smooth vertical image display.

[0076] In a third possible implementation of this embodiment, the pixel driving circuit includes a master electrode and two slave electrodes, such as... Figure 4 As shown, two slave electrodes are distributed around the main electrode. The display time for one frame of an image is divided into two display cycles. In the first display cycle, the slave electrode is connected to the main electrode located in the same pixel driving circuit as the slave electrode. In the second display cycle, the slave electrode is connected to the adjacent main electrode that is not located in the same pixel driving circuit as the slave electrode. Thus, the slave electrode connects to two adjacent main electrodes respectively within the display time of one frame of an image. Figure 4 As shown in the diagram (either vertically or horizontally), the pixel area corresponding to the slave electrode displays the pixel information corresponding to the two adjacent master electrodes within the display time of one frame of an image. When superimposed in time, it can be understood that the slave electrode displays the average value of the pixel information corresponding to the two adjacent master electrodes within the display time of one frame of an image. Thus, without increasing the physical pixels of the display device, the resolution of the image display in both the vertical and horizontal directions becomes higher, and the image display in both directions becomes more delicate and smooth.

[0077] In a fourth possible implementation of the embodiment, the pixel driving circuit includes one main electrode and three slave electrodes, the main electrode and the three slave electrodes are arranged in a four-square form, the main electrode is located at the upper left corner of the four-square form, as shown in Figure 1 . The display time of the display device for displaying one frame of image is divided into four display periods. In the four display periods of one frame of image, the slave electrode is connected to the main electrode or other main electrode adjacent to the slave electrode in at least one display period, and the pixel region corresponding to the slave electrode in the display panel displays the image corresponding to the pixel information based on the pixel information of the main electrode.

[0078] Please refer to Figure 5 , which is an example of the connection relationship between the slave electrode and the main electrode in each display period in the fourth possible implementation of the embodiment. As shown in Figure 5 , in the first display period, the main electrode is connected to the adjacent slave electrodes located at the right side, the lower side and the right lower side of the main electrode, that is, the slave electrodes are connected to the slave electrodes located in the same pixel driving circuit, that is, in the first display period, the image corresponding to the pixel information of the original image displayed on the display panel; in the second display period, the main electrode is connected to the adjacent slave electrodes located at the left side, the lower side and the left lower side of the main electrode, in this display period, the slave electrode located at the left edge of the display panel and the slave electrode located at the right edge of the display panel can not be connected to any main electrode; in the third display period, the main electrode is connected to the adjacent slave electrodes located at the upper side, the right side and the right upper side of the main electrode, in this display period, the slave electrode located at the upper edge of the display panel and the slave electrode located at the lower edge of the display panel can not be connected to any main electrode; in the fourth display period, the main electrode is connected to the adjacent slave electrodes located at the upper side, the left side and the left upper side of the main electrode, in this display period, the slave electrodes located at the four edges of the display panel can not be connected to any main electrode.

[0079] Please refer to Figure 6 , Figure 7 and Figure 8 , which are the connection relationship between the slave electrode and the main electrode in each display period, as shown in Figure 5 . In order to facilitate description, in the corresponding examples, the slave electrode at the right side of the main electrode is called a horizontal slave electrode, the slave electrode at the lower side of the main electrode is called a vertical slave electrode, and the slave electrode at the right lower side of the main electrode is called a diagonal slave electrode. Figure 6-8

[0080] As shown in Figure 6 ​As shown, in the first and third display cycles, the horizontal slave electrode is connected to the main electrode of the same pixel driving circuit (i.e., the main electrode to the left of the horizontal slave electrode). In the second and fourth display cycles, the horizontal slave electrode is connected to the main electrode to the right of the horizontal slave electrode. Thus, within the display time of one frame, the horizontal slave electrode displays the pixel information corresponding to the two adjacent main electrodes on its left and right sides. After being superimposed in time, this can be considered as the horizontal slave electrode displaying the average value of the pixel information corresponding to the two main electrodes on its left and right sides within the display time of one frame. It should be noted that the horizontal slave electrode located at the edge of the display panel may not be connected to the main electrode in the second and fourth display cycles, because there is no main electrode to the right of the horizontal slave electrode at the edge.

[0081] like Figure 7 As shown, in the first and third display cycles, the vertical slave electrode is connected to the main electrode of the same pixel driving circuit. In the second and fourth display cycles, the vertical slave electrode is connected to the adjacent main electrode below. Thus, within the display time of one frame of an image, the vertical slave electrode displays the pixel information corresponding to the two adjacent main electrodes above and below it. After being superimposed in time, it can be regarded as the vertical slave electrode displaying the average value of the pixel information corresponding to the two main electrodes above and below it within the display time of one frame of an image.

[0082] like Figure 8 As shown, in the first display cycle, the oblique slave electrode is connected to the main electrode of the same pixel driving circuit. In the second display cycle, the oblique slave electrode is connected to the adjacent main electrode on the upper right side. In the third display cycle, the oblique slave electrode is connected to the adjacent main electrode on the lower left side. In the fourth display cycle, the oblique slave electrode is connected to the adjacent main electrode on the lower right side. Thus, within the display time of one frame of an image, the oblique slave electrode carries the pixel information corresponding to the four adjacent main electrodes in time sequence. After time superposition display, it can be seen that the oblique slave electrode displays the average value of the pixel information corresponding to the four adjacent main electrodes around it within the display time of one frame of an image.

[0083] in this way, Figure 5 In the example of the connection relationship between the slave electrode and the main electrode in each display cycle, the horizontal slave electrode can be understood as displaying the average pixel information corresponding to the two horizontally adjacent main electrodes within the display time of one frame of the image; the vertical slave electrode can be understood as displaying the average pixel information corresponding to the two vertically adjacent main electrodes; and the diagonal slave electrode can be understood as displaying the average pixel information corresponding to the four adjacent main electrodes. It can be understood that, according to... Figure 5The connection relationship between the slave electrodes and the main electrodes in each display period shows the image, and the image displayed by the display device can be regarded as an image after interpolation of the original image. In this way, the resolution of the image displayed by the display device in the vertical direction, the horizontal direction and the diagonal direction is higher without increasing the physical pixels of the display device, the image displayed on the display panel can be regarded as an image after interpolation of the original image, so that the display device can realize higher resolution than the original image, improve the display quality of the image, make the image display smoother, and also alleviate the screen door effect of the display device.

[0084] In other possible embodiments of the present embodiment, the structure of the main electrodes and the slave electrodes and the corresponding connection mode in the pixel driving circuit can also be designed according to image interpolation methods such as a 3rd-order interpolation method based on a 4*4 pixel neighborhood, a Lanczos interpolation method based on an 8*8 pixel neighborhood, and the like, and the present application will not be described here.

[0085] It should be noted that, in Figure 5 In the connection relationship shown, some slave electrodes located at the edge positions of the display panel can be connected to the adjacent main electrodes in one display period or two display periods. In the second display period, the slave electrodes located at the left edge position of the display panel and the slave electrodes located at the right edge position of the display panel are not connected to the main electrodes. In the third display period, the slave electrodes located at the upper edge position of the display panel and the slave electrodes located at the lower edge position of the display panel are not connected to the main electrodes. In the fourth display period, the slave electrodes located at the four edge positions of the display panel are not connected to the main electrodes. Because the diagonal slave electrodes are located at the edge positions of the display panel in the above example, they are also located at the edge positions of the user's field of view, and they are not connected to the corresponding main electrodes in some display periods, which does not have a significant impact on the user's experience. Using such a connection mode is relatively simple in controlling the connection mode between the slave electrodes and the main electrodes, and is easy to implement.

[0086] In some other possible embodiments, the connection mode between the slave electrodes and the main electrodes is based on Figure 1 The display panel shown in the figure, the connection mode between the slave electrodes and the main electrodes is based on Figure 5Similarly, the difference is that the slave electrodes located at the edge of the display panel are connected to the corresponding main electrodes in all four display periods; for example, in the second display period, the slave electrodes located at the left edge of the display panel and the slave electrodes located at the right edge of the display panel are connected to the corresponding main electrodes in the same way as in the first display period, in the third display period, the slave electrodes located at the top edge of the display panel and the slave electrodes located at the bottom edge of the display panel are connected to the corresponding main electrodes in the same way as in the first display period, in the fourth display period, the slave electrodes located at the left edge of the display panel and the slave electrodes located at the right edge of the display panel are connected to the corresponding main electrodes in the same way as in the third display period, and the slave electrodes located at the top edge of the display panel and the slave electrodes located at the bottom edge of the display panel are connected to the corresponding main electrodes in the same way as in the second display period. In this way, the slave electrodes located at the edge of the display panel can display the pixel information of the nearest main electrode in the four display periods.

[0087] It should be noted that, in the display device shown in Figure 1 , the connection mode of the four display periods is not limited to the order shown in Figure 5 . In other possible embodiments, the connection mode of the slave electrodes and the main electrodes in the four display periods is opposite to the order of the connection mode corresponding to the four display periods in Figure 5 .

[0088] In a fifth possible embodiment of the present embodiment, the pixel driving circuit includes one main electrode and three slave electrodes, and the main electrode and the three slave electrodes are arranged in a four-quadrant form, and the main electrode is located at the lower right corner of the four-quadrant, as shown in Figure 9 . The display time of the display device for displaying one frame of image is divided into four display periods. In the four display periods of one frame of image, the slave electrodes are connected to the main electrodes or connected to other main electrodes adjacent to the slave electrodes in at least one display period, and based on the pixel information of the main electrodes, the pixel area corresponding to the slave electrodes in the display panel displays the image corresponding to the pixel information. The connection relationship between the slave electrodes and the main electrodes in the fifth possible embodiment in each display period is similar to the connection relationship example shown in Figure 5 , and those skilled in the art can deduce it by referring to Figure 1 and Figure 5 , which will not be described here in detail.

[0089] The display device provided in the above embodiment comprises a display panel and a plurality of pixel driving circuits, each pixel driving circuit corresponds to each physical pixel in the display panel, the pixel driving circuit comprises a master electrode and a slave electrode, wherein the master electrode is used to receive pixel information corresponding to the pixel driving circuit, and display an image corresponding to the pixel information in a pixel area corresponding to the master electrode in the display panel based on the pixel information; the slave electrode is used to connect the master electrode or other master electrodes adjacent to the slave electrode in at least one display period, and display an image corresponding to the pixel information in a pixel area corresponding to the slave electrode in the display panel based on the pixel information of the master electrode.
