This application claims the benefit of priority to Chinese Patent Application No. 201410581926.4 filed on Oct. 27, 2014 and entitled “PIXEL STRUCTURE, DISPLAY PANEL AND PIXEL COMPENSATION METHOD THEREFOR”, the content of which is incorporated herein by reference in its entirety.
Display panels have been widely applied at present to a handset, a Personal Digital Assistant (PDA) and other portable electronic products, e.g., a Thin Film Transistor Liquid Crystal Display (TFT-LCD), an Organic Light Emitting Diode (OLED), a Low Temperature Poly-Silicon (LTPS) display, a Plasma Display Panel (PDP), etc. In recent years, display devices with a superior display effect and a better visual effect have become increasingly favored due to their competition for the market.
A display panel consists of a plurality of pixels, and in order to enable each single pixel to display various colors, the single pixel 101 which is a color pixel is divided into three smaller sub-pixels 102 in red, green and blue in a pixel structure as illustrated in
As the display panel needs to display a picture better, the Pixel Per Inch (PPI) thereof has to be constantly improved accordingly, thus greatly lowering the transmittance of the display panel. Moreover a larger number of data lines and scanning lines required for the display panel with the high pixel per inch may come with a higher cost thereof.
In order to make the technical solutions according to the embodiments of the application more apparent, the drawings to which reference is made will be described briefly below in the description of the embodiments, and evidently the drawings in the following description are illustrative of only some of the embodiments of the application, and those ordinarily skilled in the art can further derive other drawings from these drawings without any inventive effort.
The technical solutions according to the embodiments of the application will be described below clearly and fully with reference to the drawings in the embodiments of the application, and evidently the embodiments described here are only a part but not all of the embodiments of the application. All the other embodiments which can occur to those ordinarily skilled in the art based upon the embodiments here of the application without any inventive effort shall fall into the scope of the application as claimed.
An embodiment of the application provides a pixel structure including a pixel array. The pixel array includes a plurality of pixels, each of which includes a first sub-pixel, a second sub-pixel and a third sub-pixel in different colors including any permutation and combination of red, blue and green.
Any two adjacent rows of sub-pixels in the pixel array are shared by each other and constitute a plurality of pixel dots, a first pixel dot includes a first sub-pixel and several surrounding sub-pixels adjacent to the first sub-pixel, and at least one or more of the surrounding sub-pixels and the first sub-pixel are shared by each other; and the first pixel dot includes at least one first sub-pixel, second sub-pixel and third sub-pixel, and the first pixel dot includes at least four sub-pixels.
As illustrated in
The above-described embodiment is only one of the embodiments of the application. Alternatively, the first pixel row P1, the second pixel row P2 and the third pixel row P3 in the pixel array can be arranged in various permutations and combinations but will not be limited to the structure illustrated in
The above-described embodiment is only one of the embodiments of the application. Alternatively, an alternative structure may be possible as illustrated in
This embodiment has been described in connection with a number of patterns in which the pixel array is arranged, and accordingly there may be more patterns in which the pixels are shared and displayed.
Referring to
A=C/y, where C represents a constant, and C is 1 inch;
In the conventional process and algorithm, when no sub-pixels is shared, the desirable repeated unit including the red sub-pixel, the green sub-pixel and the blue sub-pixel is a virtual pixel dot as defined according to the embodiment of the application, where the width of the virtual pixel dot is y; as illustrated in
Where the number of times that a single sub-pixel is shared is calculated according to the varying pattern in which the virtual pixel dots are arranged in the pixel array. As can be apparent from
Referring to
W=xy,
Where y=C/A, and 1<x≤3;
In the pixel array in this case, the ratio of the length to the width of a single sub-pixel is 3: W, i.e., 3A: Cx; and the panel including the pixel array including the shared pixels at a desirable PPI can be designed according to this ratio.
According to this embodiment of the application, it is provided the relationship between the pixel per inch and the ratio of the length to the width of a single sub-pixel, and in the design of the real panel, the pattern in which the pixels of the real panel are arranged and their sizes can be obtained simply by calculating the desirable PPI.
The above-described embodiment is only one of the embodiments of the application. Alternatively, as illustrated in
The above-described embodiment is only one of the embodiments of the application. Alternatively, as illustrated in
The above-described embodiment is only one of the embodiments of the application. Alternatively, the plurality of sub-pixels can be arranged zigzag in the column direction, and the horizontal spacing between the adjacent rows of sub-pixels is half the length in the direction of the rows of sub-pixels.
An embodiment of the application provides a display panel including a plurality of the pixel structures described above, and a signal driver. As illustrated in
An embodiment of the application further provides a pixel compensation method for a display panel, applicable to the pixel structure described above, where the method includes:
Sharing at least one or more of the surrounding sub-pixels and the first sub-pixel;
Providing the first pixel dot with several sub-pixels in the same color, where the total luminance of the several sub-pixels in the same color is provided evenly by the several sub-pixels in the same color, and the total luminance of the several sub-pixels in the same color is the sum of the luminances of the several sub-pixels in the same color;
Providing sub-pixels in respective colors in the first pixel dot with the total luminance at a uniform ratio thereof to the highest luminance of each sub-pixel in the respective colors, such that for each color, the ratio of the highest luminance of the sub-pixels to the total luminance of the sub-pixels is the same as the corresponding ratio for the other colors;
Providing several further second pixel dots adjacent to the first pixel dot to surround the first pixel dot, so that the sub-pixels in the first pixel dot and sub-pixels in the second pixel dots are shared by each other; and
Inputting, by the signal driver, a signal to each sub-pixel for displaying in the displaying process of the display panel, wherein the input signal is configured to control display luminance of the sub-pixel, the display luminance of each sub-pixel is a sum of a luminance of the sub-pixel in the first pixel dot and a luminance of the sub-pixel in the second pixel dot, wherein the display luminance of each sub-pixel is the highest or maximum luminance thereof.
The display luminance of each sub-pixel is limited to the highest or maximum luminance available to each sub-pixel.
Where a single sub-pixel in the pixel structure is shared twice or four times.
Particularly as can be apparent from
With the pixel structure, the display panel including the pixel structure, and the pixel compensation method for the display panel according to the embodiments of the application, such a virtual pixel dot solution is implemented that each virtual pixel dot does not include three physical sub-pixels but includes only a part of zones of several adjacent or proximate sub-pixels, that is, each sub-pixel is divided into several zones, each of which is a virtual sub-pixel of a different pixel dot; and in the case of a lower number of physical sub-pixels on the display panel, each sub-pixel and surrounding the sub-pixel are shared by each other at least once, thus improving the Pixel Per Inch (PPI) and optimizing a display effect.
The pixel structure, the display panel including the pixel structure, and the pixel compensation method for the display panel according to the embodiments of the application have been described above in details, and the principle of the application and the embodiments thereof have been set forth in this context by way of several examples, but the embodiments above have been described only for the purpose of facilitating understanding of the method of the application and the core idea thereof; and moreover those ordinarily skilled in the art can modify the embodiments and application scopes of the application without departing from the spirit of the application, and in summary the disclosure of the application will not be construed as limiting the application.
