Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like do not limit the quantity and execution order. In addition, in the description of the embodiments of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Example one
The embodiment of the invention provides a pixel moving method, which is applied to a display panel, wherein the display panel is used for displaying a first picture, and the first picture comprises a first sub-picture; the first sub-picture comprises a plurality of pixels which are arranged in an array, each pixel comprises a plurality of sub-pixels, and the sub-pixels display the first sub-picture brightness; each sub-pixel area is a sub-pixel area, and each pixel area is a pixel area; each pixel region includes a plurality of sub-pixel regions.
The method comprises the following steps:
s01, judging whether the area of the first sub-picture corresponds to the fixed display area of the display panel.
And S02, if yes, acquiring the time period for the fixed display area of the display panel to display the fixed picture.
And S03, in the period of displaying the fixed picture, each sub-pixel in the first sub-picture moves according to the respective preset track by taking the position of the sub-pixel as the coordinate origin. Wherein the movement comprises a first movement comprising a sub-pixel moving from a first sub-pixel region to an immediately adjacent second sub-pixel region.
If the second sub-pixel area is located in the pixel area before the sub-pixel moves, the sub-pixel keeps displaying the first sub-frame brightness in the first movement.
If the second sub-pixel region is located outside the pixel region where the sub-pixels were located before the sub-pixels were moved, the sub-pixels are displayed in multiple stages in the first movement, and different luminance is displayed in each stage.
The type of the Display panel applied by the above method is not limited, and the Display panel may be an LCD (Liquid Crystal Display) Display panel, an OLED (Organic Light Emitting Diode) Display panel, an AMOLED (Active Matrix Organic Light Emitting Diode) Display panel, or other types of OLEDs.
The specific content, size, format, etc. of the first picture are not limited, and may be, for example, a color picture, or a black-and-white picture, which is determined according to the actual situation. The first sprite is a partial picture of the first picture.
Here, the number of sub-pixels included in each pixel is not limited, and each pixel may include three sub-pixels, for example: referring to fig. 1, each pixel 10 includes three sub-pixels of red (R), green (G), and blue (B); each pixel may also include four sub-pixels, for example: referring to fig. 3, each pixel includes four sub-pixels of red (R), green (G), blue (B), and white (W), and of course, each pixel may also include four sub-pixels of red (R), green (G), blue (B), yellow (Y) (not shown in the figure), and so on.
The preset track is a manually set moving track, and the specific moving track needs to be determined according to actual conditions.
The sub-pixel moves from the first sub-pixel area to the second sub-pixel area which is adjacent to the first sub-pixel area, if the second sub-pixel area is located in the pixel area where the sub-pixel is located before moving, the sub-pixel keeps displaying the first color brightness in the first movement, namely the sub-pixel moves in the original pixel area, and the brightness keeps unchanged.
If the second sub-pixel region is located outside the pixel region where the sub-pixels were located before the sub-pixels were moved, the sub-pixels are displayed in multiple stages in the first movement, and different color luminances are displayed in each stage. That is, when the sub-pixels move to other pixel regions, multi-stage display is performed, and different color brightness is displayed in each stage. The number of stages is not limited here, and for example, the display may be divided into two stages or three stages, and may be specifically determined according to the scanning frequency of the display panel.
After the pixel moving method is adopted, on one hand, a fixed display area can be avoided, so that the afterimage of the display panel is greatly eliminated; on the other hand, in the first movement included in the pixel movement method, different brightness display strategies are adopted in the movement process according to the different positions of the second sub-pixel areas, so that the image flicker caused by the pixel movement can be greatly reduced, the display effect is further improved, and the product quality and the customer experience are further improved.
Optionally, in order to reduce the influence on the display effect and fully retain the content of the original display image, in the period of displaying the fixed image, in step S03, moving each sub-pixel in the first sub-image along a respective preset trajectory with its own position as the coordinate origin includes:
in the time period of displaying the fixed picture, each sub-pixel in the first sub-picture performs closed-loop movement according to a respective preset track by taking the position of each sub-pixel as a coordinate original point.
The closed-loop movement means that the sub-pixel starts from the starting point and finally returns to the starting point after moving according to a preset track. Here, the meaning of the closed-loop movement is explained by taking fig. 2 as an example. In fig. 2, the sub-pixel moves in the ab direction from sub-pixel region P0 to sub-pixel region P1, then in the bc direction from sub-pixel region P1 to sub-pixel region P2, then in the cd direction from sub-pixel region P2 to sub-pixel region P3, and finally in the da direction from sub-pixel region P3 to sub-pixel region P0.
In order to further reduce the flicker of the image caused by the pixel movement and improve the display effect, optionally, if the second sub-pixel region is located outside the pixel region where the sub-pixel is located before the sub-pixel movement, the sub-pixel is divided into multiple stages in the first movement, and each stage of displaying different brightness includes:
if the second sub-pixel area is located in the area outside the pixel area where the sub-pixel is located before moving, the sub-pixel is divided into a first stage and a second stage in the first moving process, the sub-pixel displays the second sub-picture brightness in the first stage, and displays the first sub-picture brightness in the second stage, and the second sub-picture brightness is smaller than the first sub-picture brightness.
The ratio of the second sub-picture luminance to the first sub-picture luminance is not limited, and the second sub-picture luminance may be, for example, one half, one third, one fourth, etc. of the first sub-picture luminance, which is not listed here.
In addition, the specific time distribution of the first stage and the second stage is not limited here. For example, the first phase may be one half, one third, one fourth, etc. of the time taken for the first move, and the second phase may be one half, one third, one fourth, etc. of the time taken for the first move, as long as the sum of the first phase and the second phase is the time taken for the first move. For example, if the first phase takes one-half of the time taken for the first move, then the second phase takes one-half of the time taken for the first move; if the first stage occupies one third of the time used for the first movement, the second stage occupies two thirds of the time used for the first movement; if the first phase takes one-fourth of the time taken for the first move, then the second phase takes three-fourths of the time taken for the first move. Of course, other allocation scenarios are possible and are not further enumerated here.
Optionally, the luminance of the second sub-frame is half of the luminance of the first sub-frame, in this case, the frame flicker caused by the pixel movement is very weak, and there is substantially no adverse effect on the display effect.
Alternatively, referring to fig. 3, the moving direction AB of the first movement is parallel to the arrangement direction OM of all the sub-pixels included in the pixel. Fig. 3 shows the moving direction as a → B, but the moving direction may be a ← B as shown in fig. 5. In this case, the first movement may effect a sub-pixel level movement.
The following description is made with reference to fig. 3 and 4. In fig. 3, pixel Q includes four subpixels RGBW, pixel Q1 includes four subpixels RGBW, and pixel Q1 include all subpixels shifted by one subpixel area in the a → B direction. Shifted sub-pixel distribution referring to fig. 4, the three sub-pixels GBW of pixel Q and the R sub-pixel of pixel Q1 in fig. 3 constitute a new pixel Q2. During this shift, the R sub-pixel included in the pixel Q2 first displays half of the first red luminance and then displays the first red luminance; the pixel Q2 includes three subpixels GBW displaying a first green luminance, a first blue luminance, and a first white luminance, respectively. After the above movement, the sub-pixels in the area where the pixel Q and the pixel Q1 are located are all redistributed to form a new pixel, thereby realizing the sub-pixel level movement.
The following description will be made with reference to fig. 5 and 6. In fig. 5, the pixel Q4 and the pixel Q5 include four subpixels RGBW, respectively, and all the subpixels included in the pixel Q4 and the pixel Q5 are shifted by one subpixel region in the B → a direction. Shifted sub-pixel distribution referring to fig. 6, the W sub-pixel of the pixel Q4 and the RGB sub-pixels of the pixel Q5 in fig. 5 constitute a new pixel Q6. During this shift, the W subpixel included in the pixel Q6 first displays half of the first white luminance and then displays the first white luminance; the pixel Q6 includes three RGB sub-pixels displaying a first red luminance, a first green luminance, and a first blue luminance, respectively. After the movement, the sub-pixels in the areas of the pixel Q4 and the pixel Q5 are redistributed to form a new pixel, so that the sub-pixel level movement is realized.
Alternatively, referring to fig. 7, the moving direction CD of the first movement is perpendicular to the arrangement direction OM of all the sub-pixels included in the pixel. In fig. 7, the moving direction is C → D as an example, but of course, the moving direction may be C ← D. In this case, the first movement may effect a movement at the pixel level, which is explained here in connection with fig. 7 and 8. In fig. 7, the pixel Q7, the pixel Q8, and the pixel Q9 respectively include four subpixels RGBW, and all the subpixels included in the pixel Q7, the pixel Q8, and the pixel Q9 are shifted by one subpixel region in the C → D direction. Distribution of sub-pixels after shifting as shown in fig. 8, all sub-pixels included in the pixel Q7, the pixel Q8, and the pixel Q9 in fig. 7 are shifted down by one sub-pixel region as a whole. During this shift, all the sub-pixels included in the pixel Q7, the pixel Q8, and the pixel Q9 display half of the original luminance first, and then display the entire luminance. After the above movement, the positions of all the sub-pixels included in the pixel Q7 are moved simultaneously, and the included sub-pixels are not recombined with the sub-pixels of other pixels to form new pixels, so that the pixel-level movement is realized. The pixel Q8 and the pixel Q9 are similar to the pixel Q7, and are not described in detail here.
Optionally, the first sub-pixel region is a region where the sub-pixel is located before moving. I.e. the first movement is a movement starting from the position where the sub-pixel itself is located.
Optionally, after the first movement, the sub-pixel region where the sub-pixel is located before the movement has no other sub-pixels moved in, and the sub-pixel region where the sub-pixel is located before the movement does not display the frame in the first movement. The following description is made with reference to fig. 3 and 4. In fig. 3, pixel Q3 includes four subpixels RGBW that move one subpixel area in the direction B ← a. After the W sub-pixel is shifted, in fig. 4, the W sub-pixel region of the pixel Q3 has no other sub-pixel shifted in, and the W sub-pixel region of the pixel Q3 displays no picture in the shift. Therefore, the design can be simplified, and the hardware implementation is facilitated.
Alternatively, each pixel includes a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, so that color display can be achieved.
