Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to image display technology. More particularly, to a field sequential display device and an image display method. BACKGROUND

[0002] With the development of science and technology and the improvement of people's living standards, people have higher requirements for the display effect of display devices. Through field sequential display, not only the saturation of the displayed image can be improved, but also the power consumption can be reduced.

[0003] In the prior art, for field sequential display, a frame of color image to be displayed is split into multiple single-primary-color images according to color, and a frame of display time is divided into multiple sub-fields corresponding to the single-primary-color images one by one. The single-primary-color images are displayed in the corresponding sub-fields, and the multiple single-primary-color images are switched quickly within a frame of display time, and the color display is realized by using the persistence of vision of the human eye.

[0004] However, because each pixel point in the field sequential display device includes multiple sub-pixel points, when displaying a single-primary-color image, each pixel point corresponds to a color data, and the multiple sub-pixel points included in the pixel point all display the color corresponding to the color data, resulting in a low resolution of the displayed image. SUMMARY

[0005] Embodiments of the present application provide a field sequential display device and an image display method, to solve the problem that in the existing display method, multiple sub-pixel points included in each pixel point all display one color, resulting in a low resolution of the displayed image.

[0006] In a first aspect, embodiments of the present application provide a field sequential display device, which comprises a display screen and a processor, and the processor is configured to:

[0007] receive an image to be processed, split the image to be processed to obtain multiple single-primary-color images;

[0008] determine an initial gray value corresponding to a pixel point according to the single-primary-color images;

[0009] determine a target gray value corresponding to a sub-pixel point included in the pixel point according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to a pixel point adjacent to the pixel point;

[0010] generate image data to be displayed according to the target gray value corresponding to the sub-pixel point;

[0011] The display screen is configured to control a backlight corresponding to a primary color of the single-primary-color image to be lit according to the image data to be displayed, and control liquid crystal molecules corresponding to the sub-pixel point to be deflected to a target angle.

[0012] The beneficial effects of the embodiment are as follows: after receiving the image to be processed, the processor first splits the image to be processed to obtain a plurality of single base color images; then, for each single base color image, the initial gray value corresponding to each pixel point is determined according to the single base color image. After determining the target gray value corresponding to each sub-pixel point included in each pixel point according to the initial gray value corresponding to each pixel point and the initial gray value corresponding to the adjacent pixel point of each pixel point, the image data to be displayed is generated. Finally, the display screen controls the backlight corresponding to the base color of the single base color image to be on, and controls the liquid crystal molecules corresponding to the sub-pixel point to be deflected to the target angle, so as to display the image. The present scheme determines the target gray value corresponding to each sub-pixel point included in each pixel point, so that the same pixel point can display multiple colors, and the resolution of the displayed image is effectively improved.

[0013] In some embodiments of the present application, before the processor is used to split the image to be processed to obtain a plurality of single base color images, the processor is further used to:

[0014] obtain the image to be processed and the running mode;

[0015] The running mode is a first running mode or a second running mode, the first running mode represents a mode running at a preset refresh rate, and the second running mode represents a mode running at a refresh rate N times the preset refresh rate, where N is greater than 1.

[0016] The beneficial effects of the embodiment are as follows: by obtaining the running mode before splitting the image to be processed, the image displayed according to the display data is effectively improved in resolution under the condition of meeting the refresh rate requirement.

[0017] In some embodiments of the present application, when the processor is used to determine the target gray value corresponding to the sub-pixel point included in the pixel point according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the adjacent pixel point of the pixel point, the processor is specifically used to:

[0018] If the running mode is the second running mode, the pixel point is divided into a target row pixel point belonging to a target row and a non-target row pixel point not belonging to the target row;

[0019] determine the target gray value corresponding to the sub-pixel point included in the target row pixel point according to the initial gray value corresponding to the target row pixel point and the initial gray value corresponding to the adjacent pixel point of the target row pixel point;

[0020] determine the target gray value corresponding to the sub-pixel point included in the non-target row pixel point according to the initial gray value corresponding to the adjacent pixel point of the non-target row pixel point;

[0021] If the operation mode is the first operation mode, the pixel point is not divided into the target row pixel point and the non-target row pixel point, and the target gray value corresponding to the sub-pixel point included in the pixel point is determined according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the pixel point adjacent to the pixel point.

[0022] The embodiment has the following beneficial effects: when the operation mode is the second operation mode, the pixel point is divided into the target row pixel point and the non-target row pixel point, and then different ways are used to determine the target gray value corresponding to the sub-pixel point included in the target row pixel point and the non-target row pixel point. When the operation mode is the first operation mode, the target gray value corresponding to the sub-pixel point included in the pixel point is directly determined according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the pixel point adjacent to the pixel point. According to different operation modes, the target gray value corresponding to the sub-pixel point included in the pixel point is determined, so that the determined target gray value is more accurate.

[0023] In some embodiments of the present application, when the processor is used for not dividing the pixel point into the target row pixel point and the non-target row pixel point, and determining the target gray value corresponding to the sub-pixel point included in the pixel point according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the pixel point adjacent to the pixel point, the processor is specifically used for:

[0024] determining the target sub-pixel point from the sub-pixel points included in the pixel point;

[0025] taking the initial gray value corresponding to the pixel point as the target gray value corresponding to the target sub-pixel point;

[0028] Beneficial effects of the embodiment: when the operation mode is the first operation mode, the sub-pixel points included in the pixel point are divided into target sub-pixel points and to-be-configured sub-pixel points, and then the initial gray value corresponding to the pixel point is taken as the target gray value corresponding to the target sub-pixel point. According to the two distances of the target sub-pixel points included in the pixel point and the reference pixel point and the initial gray values of the pixel point and the reference pixel point, the target gray value corresponding to the to-be-configured sub-pixel point is determined, so that the determined target gray value corresponding to the sub-pixel point is more accurate, and when the sub-pixel point displays according to the target gray value, the display effect is better and the color transition is smoother.

[0029] In some embodiments of the application, when the processor is used to determine the target gray value corresponding to the to-be-configured sub-pixel point according to the first distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the pixel point, the second distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the pixel point, and the initial gray value corresponding to the reference pixel point, the processor is specifically used for:

[0030] determining the first weight corresponding to the pixel point and the second weight corresponding to the reference pixel point according to the size relationship between the first distance and the second distance, and the sum of the first weight and the second weight is 1;

[0031] adding the product of the initial gray value corresponding to the pixel point and the first weight and the product of the initial gray value corresponding to the reference pixel point and the second weight to obtain the target gray value corresponding to the to-be-configured sub-pixel point.

[0032] Beneficial effects of the embodiment: according to the size relationship between the first distance and the second distance, the weights corresponding to the pixel point and the reference pixel point are determined, and then the target gray value corresponding to the to-be-configured sub-pixel point is calculated by combining the initial gray values corresponding to the pixel point and the reference pixel point, so that the determined target gray value corresponding to the sub-pixel point is more accurate.

[0033] In some embodiments of the application, when the processor is used to determine the target gray value corresponding to the to-be-configured sub-pixel point according to the initial gray value corresponding to the target row pixel point and the initial gray value corresponding to the pixel point adjacent to the target row pixel point, the processor is specifically used for:

[0034] determining the target sub-pixel point from the sub-pixel points included in the pixel point;

[0035] taking the initial gray value corresponding to the target row pixel point as the target gray value corresponding to the target sub-pixel point included in the target row pixel point;

[0036] For the to-be-configured sub-pixel point in the sub-pixel points included in the target row of pixel points, except for the target sub-pixel point, the reference pixel point corresponding to the to-be-configured sub-pixel point is determined from the pixel points adjacent to the target row of pixel points;

[0037] According to the third distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the target row of pixel points, the fourth distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the target row of pixel points, and the initial gray value corresponding to the reference pixel point, the target gray value corresponding to the to-be-configured sub-pixel point is determined.

[0038] The beneficial effects of the embodiment are as follows: when the running mode is the second running mode, the pixel points are divided into target rows of pixel points and non-target rows of pixel points, the target rows of pixel points are divided into target sub-pixel points and to-be-configured sub-pixel points, and then the target gray values corresponding to the two kinds of sub-pixel points are determined, so that the target gray values corresponding to the determined sub-pixel points are more accurate, and when the sub-pixel points are displayed according to the target gray values, the display effect is better and the color transition is smoother.

[0039] In some embodiments of the present application, when the processor is used to determine the target gray value corresponding to the to-be-configured sub-pixel point according to the third distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the target row of pixel points, the fourth distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the target row of pixel points, and the initial gray value corresponding to the reference pixel point, the processor is specifically used for:

[0040] According to the size relationship between the third distance and the fourth distance, the third weight corresponding to the target row of pixel points and the fourth weight corresponding to the reference pixel point are determined, and the sum of the third weight and the fourth weight is 1;

[0041] The product of the initial gray value corresponding to the target row of pixel points and the third weight and the product of the initial gray value corresponding to the reference pixel point and the fourth weight are added to obtain the target gray value corresponding to the to-be-configured sub-pixel point.

[0042] The beneficial effects of the embodiment are as follows: according to the size relationship between the third distance and the fourth distance, the weights corresponding to the target row of pixel points and the reference pixel point are determined, and then the target gray value corresponding to the to-be-configured sub-pixel point is calculated by combining the initial gray values corresponding to the target row of pixel points and the reference pixel point, so that the target gray value corresponding to the determined sub-pixel point is more accurate.

[0043] In some embodiments of the present application, when the processor is used to determine the target gray value corresponding to the sub-pixel point included in the non-target row of pixel points according to the initial gray values corresponding to the pixel points adjacent to the non-target row of pixel points, the processor is specifically used for:

[0044] According to the initial gray value corresponding to the pixel point adjacent to the non-target row pixel point, a preset high refresh rate method is used to determine the target gray value corresponding to the sub-pixel point included in the non-target row pixel point.

[0045] The beneficial effect of the embodiment is that the initial gray value corresponding to the pixel point adjacent to the non-target row pixel point is processed by the preset high refresh rate method, so that the target gray value corresponding to the sub-pixel point included in the non-target row pixel point is more accurate.

[0046] In some embodiments of the application, the preset high refresh rate method is a two-row gate line DLG method or a hardware super resolution HSR method.

[0047] The beneficial effect of the embodiment is that the DLG method or the HSR method is used to determine the target gray value corresponding to each sub-pixel point in the non-target row pixel point, so that the determined target gray value corresponding to the sub-pixel point is more accurate.

[0048] In a second aspect, the embodiments of the application provide an image display method, comprising:

[0049] Receiving an image to be processed, splitting the image to be processed to obtain a plurality of single base color images;

[0050] According to the single base color image, determining the initial gray value corresponding to the pixel point;

[0053] According to the image data to be displayed, controlling the backlight corresponding to the base color of the single base color image to be lit, and controlling the liquid crystal molecule corresponding to the sub-pixel point to be deflected to a target angle.

[0054] The beneficial effects of this embodiment are as follows: after receiving the image to be processed and the operating mode, the image to be processed is first split to obtain multiple single-primary-color images; then, for each single-primary-color image, the initial grayscale value corresponding to each pixel is determined based on the single-primary-color image. Then, the initial grayscale value corresponding to each pixel, the initial grayscale value corresponding to the pixel adjacent to each pixel, and the target grayscale value corresponding to the sub-pixel included in each pixel are determined to generate the image data to be displayed. Finally, according to the image data to be displayed, the backlight source corresponding to the primary color of the single-primary-color image is controlled to light up, and the liquid crystal molecules corresponding to the sub-pixel are controlled to deflect to the target angle to display the image. This solution determines the target grayscale value corresponding to each sub-pixel included in each pixel, so that the same pixel can display multiple colors, effectively improving the resolution of the displayed image.

[0065] For the purpose of making the objects, embodiments and advantages of the present application more clear, the following will combine the drawings in the exemplary embodiments of the present application to make a clear and complete description of the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

[0066] Based on the exemplary embodiments described in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the claims of the present application. In addition, although the disclosure in the present application is introduced according to one or several examples, it should be understood that each aspect of the disclosure can also constitute a complete embodiment.

[0067] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, but is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0068] The terms "first", "second", "third", etc. in the specification and claims of the present application and the above-described drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit the specific order or sequence, unless otherwise indicated. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, for example, those other than the order given in the embodiment illustration or description of the present application can be implemented.

[0069] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to those components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0070] With the development of technology, the way to realize color display for liquid crystal display devices has developed from filter layer display to field sequential display. In the liquid crystal display device using filter layer display, each pixel point includes a plurality of sub-pixel points, and the sub-pixel points include a filter layer corresponding to a color. The light emitted by the backlight passes through the filter layer to form colored light, and then a color image can be displayed.

[0071] For example, Figure 1 A schematic diagram of the structure of a field sequential display device for field sequential display provided by this application, such as Figure 1 As shown, the field sequential display device includes a main board and a display screen. The processor in the main board is connected to the timing control (TimingController, abbreviated as: TCON) board in the display screen. The TCON board is connected to the liquid crystal panel in the display screen. The liquid crystal panel includes backlight sources corresponding to multiple primary colors and liquid crystal molecules corresponding to each sub-pixel point.

[0072] Depend on Figure 1 It can be seen that a field sequential display device that performs field sequential display does not require a filter layer. Field sequential display splits a frame of color image to be displayed into multiple single-primary color images according to color, and divides the display time of a frame into multiple sub-field sequences corresponding to the single-primary color images. The single-primary color images are displayed in the corresponding sub-field sequences. During the display time of a frame, multiple single-primary color images are quickly switched, and color display is achieved by utilizing the persistence of vision effect of the human eye. The backlight source can provide the liquid crystal display panel with a monochrome backlight corresponding to the sub-field sequence. In the sub-field sequence, the liquid crystal molecules in the liquid crystal panel are driven and moved to the position corresponding to the single-primary color image; then the backlight source corresponding to the primary color of the single-primary color image is controlled to light up to realize the display of the single-primary color image in the corresponding field sequence. This can improve the saturation of the displayed image and reduce power consumption.

[0073] However, because each pixel in a field sequential display device includes multiple sub-pixels, when displaying a single primary color image, each pixel corresponds to a color data, and the multiple sub-pixels included in the pixel all display the color corresponding to the color data, resulting in a lower resolution of the displayed image.

[0074] For example, Figure 2 The color data diagram of the sub-pixel points corresponding to the color image provided in this application; Figure 2 As shown, Figure 2 Each square in the image represents a sub-pixel, and a pixel consists of three sub-pixels. For example, sub-pixels with color data of R11, G11, and B11 constitute a pixel. In a color image, the sub-pixels in a pixel have different color data: red, green, and blue.

[0075] The color image can be split into single primary color images. Based on the above example, Figure 3 The color data diagram of the sub-pixel points corresponding to the split single primary color image provided in this application is as follows: Figure 3 As shown, the color image can be split into three single-color images. Figure 3The first color data diagram from top to bottom is a color data diagram of a sub-pixel point corresponding to a single-primary-color image with a red primary color, the second color data diagram is a color data diagram of a sub-pixel point corresponding to a single-primary-color image with a green primary color, and the third color data diagram is a color data diagram of a sub-pixel point corresponding to a single-primary-color image with a blue primary color. In the color data diagram of the sub-pixel point corresponding to the single-primary-color image, the sub-pixel points included in the same pixel point correspond to the same color data, and the plurality of sub-pixel points included in the pixel point display the color corresponding to the color data, thereby causing the problem of low resolution of the displayed image.

[0076] To solve the problems in the prior art, the inventors have found, in the process of researching an image display method, that, in order to improve the resolution of a displayed image, for the same pixel point, the sub-pixel points in the pixel point can display different colors corresponding to the same single primary color, so as to improve the resolution. After obtaining a to-be-processed image, for each single-primary-color image, an initial gray value corresponding to each pixel point is determined; then, according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to a pixel point adjacent to the pixel point, a target gray value corresponding to a sub-pixel point included in the pixel point is determined. After generating to-be-displayed image data according to the target gray value corresponding to the sub-pixel point, the to-be-displayed image data is displayed, which can effectively improve the resolution of the displayed image. Based on the above inventive concept, the image display scheme in the present application is designed.

[0077] The application scenario of the image display method provided in the present application is described below by way of example.

[0078] For example, in this scenario, a user watches a video using a field sequential display device, and the field sequential display device receives a current frame image, processes the current frame image as a to-be-processed image, improves the resolution, and then improves the display effect.

[0079] The field sequential display device splits the to-be-processed image to obtain a plurality of single-primary-color images, so as to facilitate subsequent field sequential display. Then, for each single-primary-color image, an initial gray value corresponding to each pixel point is determined.

[0080] Then, according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to a pixel point adjacent to the pixel point, a target gray value corresponding to a sub-pixel point included in the pixel point is determined; then, to-be-displayed image data is generated according to the target gray value corresponding to the sub-pixel point; finally, an image is displayed according to the to-be-displayed image data. Each sub-pixel point corresponds to a different color, which can improve the resolution of the displayed image.

[0081] It should be noted that the above scenario is only an example of an application scenario provided by the embodiments of the present application, and the embodiments of the present application do not limit the actual forms of various devices included in the scenario or the interaction mode between the devices. In the specific application of the scheme, the actual demand can be set.

[0082] The technical solutions of the present application will be described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments.

[0083] Figure 4 The flowchart of the image display method provided in the present application is shown in the figure. The execution subject of the method can be a field sequential display device. The method in the present embodiment can be realized by software, hardware or a combination of software and hardware.

[0084] As shown in Figure 4 , the processor in the field sequential display device is configured to perform the following steps:

[0085] S401: receiving an image to be processed, and splitting the image to be processed to obtain a plurality of single-primary-color images.

[0086] In this step, after the video input interface or the wireless data transmission module in the field sequential display device receives the image to be processed, it is transmitted to the processor for processing. The processor can split it into a plurality of single-primary-color images.

[0087] For example, the data corresponding to each pixel point in the image to be processed is red-green-blue (RGB) data, and the RGB data is the gray value corresponding to the red primary color, the gray value corresponding to the green primary color, and the gray value corresponding to the blue primary color.

[0088] The gray value corresponding to the red primary color in the RGB data can be taken out as the initial gray value corresponding to the pixel point, and a single-primary-color image with a red primary color is obtained.

[0089] The gray value corresponding to the green primary color in the RGB data can be taken out as the initial gray value corresponding to the pixel point, and a single-primary-color image with a green primary color is obtained.

[0090] The gray value corresponding to the blue primary color in the RGB data can be taken out as the initial gray value corresponding to the pixel point, and a single-primary-color image with a blue primary color is obtained.

[0091] S402: determining the initial gray value corresponding to the pixel point according to the single-primary-color image.

[0092] After the processor splits the image to be processed to obtain a plurality of single-primary-color images, for each single-primary-color image, the initial gray value corresponding to each pixel point is determined according to the single-primary-color image.

[0093] S403: determining the target gray value corresponding to the sub-pixel point included in the pixel point according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the adjacent pixel point of the pixel point.

[0094] After the processor obtains the initial gray value corresponding to each pixel point, the target gray value corresponding to the sub-pixel point included in the pixel point can be determined according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the adjacent pixel point of the pixel point.

[0095] First, the target sub-pixel point is determined from the sub-pixel points included in the pixel point, and then the initial gray value corresponding to the pixel point is taken as the target gray value corresponding to the target sub-pixel point.

[0096] For the to-be-configured sub-pixel point other than the target sub-pixel point in the sub-pixel points included in the pixel point, the reference pixel point corresponding to the to-be-configured sub-pixel point is determined from the adjacent pixel points of the pixel point.

[0097] Then, the target gray value corresponding to the to-be-configured sub-pixel point is determined according to the first distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the pixel point, the second distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the pixel point, and the initial gray value corresponding to the reference pixel point.

[0098] S404: generating to-be-displayed image data according to the target gray value corresponding to the sub-pixel point.

[0099] After the processor obtains the target gray value corresponding to each sub-pixel point, the to-be-displayed image data can be generated by combining the target gray values.

[0100] The display screen is configured to control the backlight corresponding to the base color of the single-base-color image to be lit according to the to-be-displayed image data, and control the liquid crystal molecules corresponding to the sub-pixel point to be deflected to a target angle.

[0101] The processor transmits the to-be-displayed image data to the TCON board in the display screen, the TCON board converts the to-be-displayed image data to obtain driving data, and then transmits the driving data to the liquid crystal panel, drives the backlight corresponding to the base color of the single-base-color image to be lit, drives the liquid crystal in the liquid crystal panel to be deflected to a corresponding angle, and the monochromatic backlight emitted by the backlight can pass through the liquid crystal molecules to display a corresponding color, so that the display screen can display the single-base-color image.

[0102] The field sequential display device provided by the embodiment comprises a display screen and a processor; the processor is configured to, after obtaining a to-be-processed image, first split the to-be-processed image to obtain a plurality of single-primary-color images; then, for each single-primary-color image, determine an initial gray value corresponding to each pixel point according to the single-primary-color image; then, after determining a target gray value corresponding to a sub-pixel point included by each pixel point according to the initial gray value corresponding to each pixel point and the initial gray value corresponding to the adjacent pixel point of each pixel point, generate to-be-displayed image data; finally, the display screen controls the backlight corresponding to the primary color of the single-primary-color image to light up according to the to-be-displayed image data, and controls the liquid crystal molecules corresponding to the sub-pixel point to deflect to a target angle, so as to display an image. The scheme determines the target gray value corresponding to the sub-pixel point included by the pixel point, so that the same target value pixel point can display multiple colors, effectively improves the resolution of the displayed image, and improves the display effect.

[0103] The processor can also obtain a running mode before splitting the to-be-processed image, and then the case of determining the target gray value corresponding to the sub-pixel point according to the running mode is described.

[0104] The processor obtains the to-be-processed image and the running mode before splitting the to-be-processed image to obtain a plurality of single-primary-color images; and determines the target gray value corresponding to the sub-pixel point in combination with the running mode after obtaining the plurality of single-primary-color images.

[0105] The running mode is a first running mode or a second running mode, the first running mode represents a mode of running at a preset refresh rate, and the second running mode represents a mode of running at a refresh rate N times the preset refresh rate, where N is greater than 1.

[0106] It should be noted that the preset refresh rate can be 60 Hz, 120 Hz, 240 Hz, etc., and the preset refresh rate is not limited in the embodiment of the application and can be set according to actual conditions.

[0107] If the running mode is the second running mode, the pixel points are divided into target row pixel points belonging to a target row and non-target row pixel points not belonging to the target row.

[0108] It should be noted that the target row is an odd-numbered row or an even-numbered row.

[0109] In the second running mode, a high refresh rate can be achieved by using a dual line gate (DLG) technology or a hardware super resolution (HSR) technology. The DLG technology reduces the longitudinal pixel rendering accuracy, only renders target rows, and then copies the data of the target rows to non-target rows for display. For example, only the 1st, 3rd, 5th, and 7th rows are rendered, the data of the 1st row is copied to the 2nd row, the data of the 3rd row is copied to the 4th row, and the process is repeated. At this time, the number of longitudinal refreshes is reduced by half, and thus the refresh time is reduced by half, thereby improving the refresh rate of the display screen.

[0110] The HSR technology has a similar basic principle to the DLG technology, and also compresses the longitudinal pixels, only renders target rows, and displays non-target rows by fusing the information of adjacent two rows. Therefore, compared with the DLG technology, the picture using the HSR technology can make the color and lines of the entire picture more natural and clear after fusing the pixels of the even rows.

[0111] Further, the target gray values of the sub-pixel points included in the target row pixel points can be determined according to the initial gray values of the target row pixel points and the initial gray values of the pixel points adjacent to the target row pixel points.

[0112] The target gray values of the sub-pixel points included in the non-target row pixel points can be determined according to the initial gray values of the pixel points adjacent to the non-target row pixel points.

[0113] Specifically, the target gray values of the sub-pixel points in the non-target row pixel points can be determined by using a preset high refresh rate method.

[0114] It should be noted that the preset high refresh rate method is a DLG method or an HSR method. When the DLG method is used, the target gray values of the sub-pixel points in the target rows are used as the target gray values of the sub-pixel points in the non-target rows.

[0115] For example, when the target rows are odd rows, the target gray values of the sub-pixel points in the 1st row are used as the target gray values of the sub-pixel points in the 2nd row, the target gray values of the sub-pixel points in the 3rd row are used as the target gray values of the sub-pixel points in the 4th row, and the process is repeated, to obtain the target gray values of the sub-pixel points in each non-target row.

[0116] When the HSR method is used, the target gray values of the pixel points in each non-target row are obtained by using the target gray values of the pixel points in the target rows adjacent to the non-target row for fusion calculation.

[0117] For example, the target behavior is odd rows, and the target gray value of the sub-pixel point in the first row and the target gray value of the sub-pixel point in the third row are taken as the target gray value of the sub-pixel point in the second row. The fusion mode is the fusion mode in the HSR technology.

[0118] If the running mode is the first running mode, the pixel points are not divided into target row pixel points and non-target row pixel points, and the target gray value corresponding to the sub-pixel point included by the pixel point is determined according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the pixel point adjacent to the pixel point.

[0119] The field sequential display device provided in the embodiment divides the pixel points into target row pixel points and non-target row pixel points when the running mode is the second running mode, and then determines the target gray value corresponding to the sub-pixel points included by the two in different ways. When the running mode is the first running mode, the target gray value corresponding to the sub-pixel points included by the pixel point is directly determined according to the initial gray value corresponding to the pixel point and the initial gray value corresponding to the pixel point adjacent to the pixel point. According to different running modes, the target gray value corresponding to the sub-pixel points included by the pixel point is determined, so that the determined target gray value is more accurate.

[0120] Further, on the basis of the above-mentioned embodiments, the processor determines the target gray value corresponding to each sub-pixel point when the running mode is the first running mode. Figure 5 The flowchart for determining the target gray value corresponding to each sub-pixel point provided in the present application is shown in the following Figure 1 The processor in the field sequential display device is configured to perform the following steps:

[0121] S501: From the sub-pixel points included by the pixel point, a target sub-pixel point is determined.

[0122] After the processor obtains the initial gray value corresponding to each pixel point, if the obtained running mode is the first running mode, the pixel points do not need to be divided into target row pixel points and non-target row pixel points. For each pixel point, a target sub-pixel point is determined from the sub-pixel points included by the pixel point.

[0123] It should be noted that the method of determining the target sub-pixel point can be to randomly select a sub-pixel point from the sub-pixel points included by the pixel point as the target sub-pixel point.

[0124] The method of determining the target sub-pixel point can also be to take the sub-pixel point corresponding to the single primary color from the sub-pixel points included by the pixel point as the target sub-pixel point.

[0125] The method of determining the target sub-pixel point can also be to take the sub-pixel point located at the center from the sub-pixel points included by the pixel point as the target sub-pixel point according to the arrangement layout of the sub-pixel points.

[0126] The embodiment of the present application does not limit the method for determining the target sub-pixel point, and the target sub-pixel point can be determined according to actual conditions.

[0127] S502: Taking the initial gray value corresponding to the pixel point as the target gray value corresponding to the target sub-pixel point.

[0128] After the processor determines the target sub-pixel point, the initial gray value corresponding to the pixel point can be taken as the target gray value corresponding to the target sub-pixel point.

[0129] S503: For each to-be-configured sub-pixel point in the sub-pixel points included in the pixel point, except the target sub-pixel point, a reference pixel point corresponding to the to-be-configured sub-pixel point is determined from the pixel points adjacent to the pixel point.

[0130] After the processor determines the target sub-pixel point, for each to-be-configured sub-pixel point in the sub-pixel points included in the pixel point, except the target sub-pixel point, a reference pixel point corresponding to the to-be-configured sub-pixel point is determined from the pixel points adjacent to the pixel point.

[0131] It should be noted that the manner of selecting the reference pixel point can be that a pixel point closest to the pixel point is selected from the pixel points adjacent to the pixel point as the reference pixel point.

[0132] The manner of selecting the reference pixel point can also be that a pixel point is randomly selected from the pixel points adjacent to the pixel point as the reference pixel point.

[0133] The manner of selecting the reference pixel point can also be that pixel points belonging to the same row as the pixel point are determined from the pixel points adjacent to the pixel point, and then a pixel point is randomly selected from the pixel points as the reference pixel point.

[0134] The embodiment of the present application does not limit the manner of selecting the reference pixel point, and the manner of selecting the reference pixel point can be determined according to actual conditions.

[0135] S504: According to the first distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the pixel point, the second distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the pixel point, and the initial gray value corresponding to the reference pixel point, a target gray value corresponding to the to-be-configured sub-pixel point is determined.

[0136] After the processor determines the reference pixel point, according to the first distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the pixel point, the second distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the pixel point, and the initial gray value corresponding to the reference pixel point, a target gray value corresponding to the to-be-configured sub-pixel point is determined.

[0137] Specifically, first, the first weight corresponding to the pixel point and the second weight corresponding to the reference pixel point are determined according to the size relationship between the first distance and the second distance. If the first distance is greater than or equal to the second distance, the first weight is greater than or equal to the second weight. If the first distance is less than the second distance, the first weight is less than the second weight, and the sum of the first weight and the second weight is 1.

[0138] Further, the product of the initial gray value corresponding to the pixel point and the first weight and the product of the initial gray value corresponding to the reference pixel point and the second weight are added to obtain the target gray value corresponding to the to-be-configured sub-pixel point.

[0139] For example, for a single-primary-color image corresponding to a red primary color, the target gray value corresponding to the to-be-configured sub-pixel point can be calculated according to the formula , wherein R′ ij represents the target gray value corresponding to the to-be-configured sub-pixel point, R ij represents the initial gray value corresponding to the pixel point, R i(j+1) represents the initial gray value corresponding to the reference pixel point, is the first weight corresponding to the pixel point, is the second weight corresponding to the reference pixel point.

[0140] For example, on the basis of the above example, Figure 6 the color data of the sub-pixel corresponding to the single-primary-color image determined according to the target gray value provided in the present application Figure 1 , as shown in Figure 6 ,* ij represents the target gray value corresponding to the target sub-pixel point,* ij and* ij represents the target gray value corresponding to the to-be-configured sub-pixel point. It can be seen that the gray values of the sub-pixels included in one pixel point are different, and multiple colors can be displayed, and the resolution is higher.

[0141] It should be noted that if the reference pixel point is not determined according to the manner of selecting the reference pixel point, the initial gray value corresponding to the pixel point can be used as the target gray value corresponding to the to-be-configured sub-pixel point.

[0142] The field sequential display device provided in the embodiment divides the sub-pixels included in the pixel point into target sub-pixels and to-be-configured sub-pixels when the running mode is the first running mode, and then uses the initial gray value corresponding to the pixel point as the target gray value corresponding to the target sub-pixel. The target gray value corresponding to the to-be-configured sub-pixel point is determined according to the two distances of the target sub-pixels included in the pixel point and the reference pixel point and the initial gray values of the pixel point and the reference pixel point, so that the determined target gray value corresponding to the sub-pixel is more accurate, and the display effect is better and the color transition is smoother when the sub-pixel is displayed according to the target gray value.

[0143] Further, on the basis of the above-mentioned embodiments, the embodiments of the present application explain the case that the processor determines the target gray value corresponding to each sub-pixel point of the target row pixel point when the running mode is the second running mode. Figure 7 The flowchart for determining the target gray value corresponding to each sub-pixel point provided by the present application Figure 2 The processor in the field sequential display device is configured to perform the following steps:

[0144] S701: Determine the target sub-pixel point from the sub-pixel points included in the target row pixel point.

[0145] S702: Take the initial gray value corresponding to the target row pixel point as the target gray value corresponding to the target sub-pixel point included in the target row pixel point.

[0146] S703: For the to-be-configured sub-pixel point other than the target sub-pixel point in the sub-pixel points included in the target row pixel point, determine the reference pixel point corresponding to the to-be-configured sub-pixel point from the pixel points adjacent to the target row pixel point.

[0147] It should be noted that the steps S701-S703 are similar to the steps S501-S503 in the second embodiment, and will not be described here.

[0148] S704: Determine the target gray value corresponding to the to-be-configured sub-pixel point according to the third distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the target row pixel point, the fourth distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the target row pixel point, and the initial gray value corresponding to the reference pixel point.

[0149] After the processor obtains the reference pixel point, the target gray value corresponding to the to-be-configured sub-pixel point can be determined according to the third distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the target row pixel point, the fourth distance between the to-be-configured sub-pixel point and the target sub-pixel point included in the reference pixel point, the initial gray value corresponding to the target row pixel point, and the initial gray value corresponding to the reference pixel point.

[0150] Specifically, first, the third weight corresponding to the target row pixel point and the fourth weight corresponding to the reference pixel point are determined according to the size relationship between the third distance and the fourth distance. If the third distance is greater than or equal to the fourth distance, the third weight is greater than or equal to the fourth weight. If the third distance is less than the fourth distance, the third weight is less than the fourth weight, and the sum of the third weight and the fourth weight is 1.

[0151] Then, the product of the initial grayscale value corresponding to the target row pixel and the third weight and the product of the initial grayscale value corresponding to the reference pixel and the fourth weight are added together to obtain the target grayscale value corresponding to the sub-pixel to be configured.

[0152] It should be noted that if the reference pixel is not determined by the method of selecting the reference pixel, the initial grayscale value corresponding to the pixel in the target row can be used as the target grayscale value corresponding to the sub-pixel to be configured.

[0153] For example, based on the above example, Figure 8 The color data of the sub-pixel points corresponding to the single primary color image determined according to the target grayscale value provided by this application Figure 2 ,like Figure 8 As shown, * ij Indicates the target grayscale value corresponding to the target sub-pixel point, *′ ij and*" ij Indicates the target grayscale value corresponding to the sub-pixel to be configured, *′ ij ~ and *″ ij ~ represents the target grayscale value corresponding to the sub-pixel in the non-target row pixel. It can be seen that the grayscale values ​​of the sub-pixels included in a pixel are different, and multiple colors can be displayed with higher resolution.

[0154] The field sequential display device provided by this embodiment divides the pixel points into target row pixel points and non-target row pixel points when the operating mode is the second operating mode, and then divides the target row pixel points into target sub-pixel points and sub-pixel points to be configured, and then determines the target grayscale values ​​corresponding to the two sub-pixel points, so that the target grayscale values ​​corresponding to the determined sub-pixel points are more accurate, and when the sub-pixel points are displayed according to the target grayscale values, the display effect is better and the color transition is smoother.

[0155] In this application, an image display method is also provided, and the steps may be:

[0156] receiving an image to be processed, and splitting the image to be processed to obtain a plurality of single-primary-color images;

[0157] Determining an initial grayscale value corresponding to a pixel point according to the single primary color image;

[0159] Generate image data to be displayed according to the target grayscale value corresponding to the sub-pixel point;

[0160] According to the image data to be displayed, the backlight source corresponding to the primary color of the single primary color image is controlled to light up, and the liquid crystal molecules corresponding to the sub-pixel points are controlled to deflect to a target angle.
