Description

Multi-color data processing method and display pixel layout for the method

technical field

The present invention relates to a multi-color data processing method and a display pixel layout used in the multi-color data processing method, in particular to a multi-color data processing method and a display pixel layout that take into account resolution and brightness requirements

Background technique

Figure 1 shows a traditional red (R), green (G), blue (B) three-color pixel layout arrangement. FIG. 2A and FIG. 2B are schematic diagrams showing two pixel layout arrangements of red (R), green (G), blue (B) and white (W) proposed by Samsung Electronics Corporation of Korea.

The display color technology of adding white sub-pixel (white sub-pixel) in the pixel layout of the display can bring about the effect of improving the light use efficiency of the liquid crystal display to increase the brightness or reduce the power consumption of the backlight, which is for example LCD TV or handheld The application of the liquid crystal device has obvious performance gain.

As shown in FIG. 2A , the displayed R, G, B, and W sub-pixels are arranged in stripes. Comparing FIG. 1 and FIG. 2A, it can be seen that under the same pixel allocation area, when W sub-pixels are added, the individual areas of the RGB three-color sub-pixels will be reduced to three quarters of the original area, resulting in a decrease in the aperture ratio. Furthermore, the design of the display panel incorporating W sub-pixels requires a large number of data lines for coordination, which will cause the number of data ICs to increase to four-thirds of the original, greatly increasing the cost.

FIG. 2B shows another layout in which RGBW sub-pixels are arranged in a checkerboard arrangement. Comparing FIG. 1 and FIG. 2B, it can be seen that under the same pixel allocation area, this design also has the problem of adding W sub-pixels, resulting in the reduction of the individual areas of the RGB three-color sub-pixels to three quarters of the original. Furthermore, because a group of RGBW is arranged in a square consisting of four areas, although the number of data ICs can be reduced to two-thirds of the original, the number of scanning lines is doubled instead, which greatly increases the number of scanning ICs. increase cost.

In view of this, Kodak also proposes an RGBW pixel layout design that does not change the area of individual sub-pixels. Figure 3A shows the traditional RGB three-color pixel layout, and Figure 3B shows the RGBW pixel layout designed by Kodak. Comparing Fig. 3A and Fig. 3B, it can be seen that because this design is based on the original RGB three-color pixel layout, W sub-pixels are added without changing the size of individual sub-pixels, so the area of the RGB three-color sub-pixels remains the same. Moreover, the area of the W sub-pixel is also designed to be the same as that of the other three-color sub-pixels.

However, although this design can maintain the size of the original sub-pixel area, it has the obvious disadvantage of resolution degradation.

Because a pixel unit of the RGB three-color system is defined as a set of three sub-pixels of RGB, and a pixel unit of the RGBW four-color system is defined as a set of four sub-pixels of RGBW, a comparison of Fig. 3A and Fig. 3B shows that Kodak's design The horizontal distance Px' of the pixel unit is 4/3 times of the horizontal distance Px of a pixel unit in the general RGB pixel layout, so its resolution will be reduced to 3/4 of the original one. For example, according to this design, when the resolution of the original RGB three-color system display panel is 176×RGB×220, adding additional W sub-pixels to form an RGBW four-color system display panel, the resolution will be reduced to 132×RGBW× 220 (176*3/4=132).

Detailed ways

4A to 4D are schematic diagrams showing the pixel layout of a red (R) green (G) blue (B) white (W) four-color system display of the present invention, and a pixel defined by the multi-color data processing method described later. unit composition.

Taking Fig. 4A as an example, the RGBW four-color pixel layout of the present invention consists of a plurality of rows each composed of red (R), green (G), blue (B), and white (W) sub-pixels, and the pixels The sub-pixels of the layout are arranged according to the following rules:

1. Two adjacent sub-pixels located in the same row have different colors, that is, R, G, B, and W sub-pixels appear discontinuously and repeatedly when arranged along the same horizontal row; and

2. The two sub-pixels of the same color respectively located in two adjacent rows form two sub-pixel position dislocations along the arrangement direction. Taking Figure 4A as an example, when the R sub-pixel in the first row appears at the first arrangement position at the far left, the first R sub-pixel at the left end of the second row appears at the third arrangement position, that is, the two are shifted from each other The two sub-pixels are arranged in the same position, and the rest of the sub-pixels are also arranged in the same way.

When W sub-pixels are added to the RGB three-color system to increase display brightness, in order to maintain the resolution of the original RGB three-color system, the present invention uses the multi-color data processing method described later to redefine the RGBW four-color system after adding W sub-pixels of a pixel unit. Under the condition of maintaining the original resolution, a pixel unit must be composed of three sub-pixels. Therefore, according to the design of the present invention, a pixel unit is composed of one of the following four sub-pixel combinations:

1.RGB (the pixel unit 10 shown in the bold black line in Fig. 4A)

2. WRG (pixel unit 12 shown in bold black line in FIG. 4B )

3. BWR (pixel unit 14 shown in bold black line in Figure 4C)

4.GBW (pixel unit 16 shown in bold black line in Figure 4D)

According to the pixel unit definition method of the present invention, although the composition of each pixel unit lacks one color compared with the RGBW four colors, through the pixel layout design of the present invention, the missing color of the pixel unit will appear in the pixel unit The most adjacent positions of top, bottom, left and right are used for color compensation. Taking the pixel unit 10 in FIG. 4A as an example composed of RGB sub-pixels, the W sub-pixel lacking in the pixel unit 10 will appear on the left side of the R sub-pixel, the right side of the B sub-pixel and the top and bottom of the G sub-pixel, that is, all adjacent The pixel units 12 , 14 and 16 all have W sub-pixels at the sub-pixel positions closest to the pixel unit 10 , so as to obtain the best color compensation effect. The missing colors of the other pixel units 12 , 14 and 16 compared with the RGBW four colors also appear in the same way.

5A, 5B, 6A and 6B are schematic diagrams for illustrating the design of the above-mentioned special pixel unit definition in conjunction with the multi-color data processing method of the present invention.

Carry out the multi-color data processing method of the present invention, at first select the pixel Pixel (I) of an original three-color system as initial operation unit, as shown in Figure 5A, Pixel (I) comprises R _I , G _I and B _I subunits pixels. According to the design of the present invention, at first the grayscale value of the original R _I , G _I , B _I three-color image data is input into a four-color conversion element 22, and any whitening algorithm is used to convert it into R _I G _I B _I W _I In the four-color data format, after the grayscale value of the sub-pixel W _I is determined, subsequent color compensation processing is performed.

5B is a schematic diagram showing the color compensation process performed when the pixel Pixel (I) of the original three-color system is converted into the first type of pixel unit (including RGB sub-pixels) defined according to the present invention. As shown in Figure 5B, the first type of pixel unit 10 defined by the four-color system of the present invention includes R _I G _I B _I sub-pixels, which lack white relative to the RGBW four colors, but through the pixel layout arrangement of the present invention, the The lack of white will appear in the nearest up, down, left, and right positions of the pixel unit 10 for color compensation (W _L , W _T , W _R , and W _D ). When performing color compensation processing, after the pixels of the original three-color system are converted by four colors, compared with the R _I G _I B _I sub-pixels contained in the pixel unit 10, the redundant W _I grayscale values can be output to the surrounding pixel units. The W sub-pixel area includes the W _R sub-pixel of the pixel unit 12, the W _T and W _D sub-pixels of the pixel unit 14, and the W _L sub-pixel of the pixel unit 16. On the other hand, after the three-color pixels corresponding to the pixel unit 12 are converted into the four-color data format in the same way, the grayscale value of the redundant sub-pixel B _R is input to the B _I area of the pixel unit 10; the three-color pixels corresponding to the pixel unit 14 After the pixel is converted into the four-color data format in the same way, the grayscale value of the redundant sub-pixels G _T and G _D is input to the G _I area of the pixel unit 10; the three-color pixel corresponding to the pixel unit 16 is converted into the four-color pixel in the same way The grayscale value of the redundant sub-pixel R _L after formatting is input to the R _I region of the pixel unit 10 . Finally, as shown in Figure 5A, the RGB three-color compensation value input by the adjacent pixel unit and the original three-color pixel Pixel (I) are converted into the RGB three-color grayscale value in the four-color format, which can be respectively input to R, G, and B pixel correlators 24, 26, and 28 perform correlation operations according to a preset weight, and the obtained value is the gray scale value actually output by the R _I G _I B _I sub-pixels of the first type of pixel unit 10 . The preset weights can be adjusted according to the displayed visual effects.

Then, from the original three-color system pixels, select the next pixel Pixel (I+1) for calculation and processing, as shown in Figure 6A, Pixel (I+1) includes R _I+1 , G _I+1 , B _{I+ 1} sub-pixel. Similarly, R _I+1 , G _I+1 , and B _I+1 sub-pixel grayscale values of Pixel (I+1) are input into a four-color conversion element 22, and converted into R _I+1 by using any whitening algorithm G _I+1 B _I+1 W _I+1 four-color data format, after determining the grayscale value of the sub-pixel W _I+1 , subsequent color compensation processing is performed.

6B is a schematic diagram showing the color compensation process performed when the pixel Pixel (I+1) of the original three-color system is converted into the second type of pixel unit (including WRG sub-pixels) defined according to the present invention. As shown in FIG. 6B, the second type of pixel unit 12 defined by the four-color system of the present invention includes W _I+1 R _I+1 G _I+1 sub-pixels, and through the pixel layout arrangement of the present invention, the missing blue It will appear at the most adjacent positions of the pixel unit 12 ( _BL , _BT , _BR , and _BD belong to the pixel units around the pixel unit 12) to obtain a good color compensation effect. When performing color compensation processing, after the pixels of the original three-color system are converted by four colors, compared with the W _I+1 R _I+1 G _I+1 sub-pixels contained in the pixel unit 12, the redundant B _I+1 gray scale The value can be output to the B sub-pixel area of the surrounding pixel unit, including the BL _sub -pixel of the pixel unit 10, the BR _sub -pixel of the pixel unit 14, and the _BT , B _D sub-pixels of the pixel unit 16. On the other hand, after the three-color pixels corresponding to the pixel unit 10 are converted to the four-color format in the same way, the grayscale value of the redundant sub-pixel W _L can be input to the W _I+1 area of the pixel unit 12; After the three-color pixel is converted into the four-color format in the same way, the grayscale value of the redundant sub-pixel G _R can be input to the G _I+1 area of the pixel unit 12; the three-color pixel corresponding to the pixel unit 16 is converted into the four-color format in the same way. The grayscale values of the redundant sub-pixels R _T and R _D after the color format can be input to the area R _I+1 of the pixel unit 12 . Finally, as shown in Figure 6A, the WRG three-color compensation value input by the adjacent pixel unit and the original three-color pixel Pixel (I+1) are converted into the WRG three-color grayscale value in the four-color format, which can be respectively Input to the W, R, and G pixel correlators 30, 24, and 26, and perform a correlation operation according to a preset weight, and the obtained value is W _I+1 R _I+1 G _I+1 of the second type of pixel unit 12 The grayscale value actually output by the three-color sub-pixel.

Similarly, the selected pixels from the original three-color system are sequentially converted into the third type of pixel unit 14 (composed of BWR sub-pixels) and the fourth type of pixel unit 16 (composed of GBW sub-pixels), until all the three-color pixels are converted into original The invention defines four types of four-color system pixel units as shown in FIGS. 4A to 4D .

Fig. 7 is a flowchart illustrating the steps of the multicolor data processing method of the present invention.

Step S0: start.

Step S2: Capture the R, G, and B sub-pixel image data of a pixel unit in the original three-color system to perform four-color conversion processing, so as to convert the image data into RGBW four-color grayscale values.

Step S4: Select one of the four types of pixel units defined in the present invention as a selected pixel unit, and compare the sub-pixel color of the selected pixel unit with the RGBW four-color gray scale value. The four-color gray scale values include the gray scale values of the sub-pixel colors belonging to the selected pixel unit and the gray scale values of other sub-pixel colors not belonging to the selected pixel unit.

Step S6: Output the sub-pixel color gray-scale values of the four-color gray-scale values that do not belong to the selected pixel unit to adjacent pixel units, and at the same time make the selected pixel unit receive the sub-pixel gray-scale values input from the adjacent pixel units.

Step S8: Carry out a correlation coefficient calculation between the grayscale value input by the adjacent pixel unit and the grayscale value of the sub-pixel color belonging to the selected pixel unit among the four-color grayscale values, so as to determine the grayscale actually output by each sub-pixel of the selected pixel unit order value.

Step S10: Convert the pixel units of the three-color system into the pixel units of the four-color system defined in the present invention in sequence, and judge whether all the pixel units of the original three-color system have been converted, if so, go to the next step; if not, Jump back to step S2.

Step S12: end.

Through the data processing method of the present invention in which four-color data format conversion is combined with color compensation calculation, a pixel unit defined by three sub-pixels can become an effective display pixel unit under the RGBW four-color system. Therefore, the present invention can still maintain the resolution of the original RGB three-color system when adding white sub-pixels to increase the brightness, and the area of the RGB three-color sub-pixels can still remain unchanged, and the area of the white sub-pixels can also be changed. Similar to the sub-pixel area of other three colors, an optimal design with both resolution and brightness is obtained.

Furthermore, the method of whitening calculation processing performed by the four-color conversion element 40 in the present invention is not limited. For example, the method disclosed in Taiwan Patent Publication No. 200424952 as shown in FIG. The element 50 effectively converts RGB three-color grayscale data into R'G'B'W' four-color grayscale data.

The pixel layout of the present invention only needs to meet the requirement that two adjacent sub-pixels located in the same row have different colors, and two sub-pixels of the same color respectively located in two adjacent rows form dislocations of two sub-pixel positions along the arrangement direction. As for the arrangement position of RGBW, it can be changed arbitrarily. FIG. 9 shows another arrangement, wherein the pixel units defined according to the present invention are GBR pixel unit 60 , BRW pixel unit 62 , RWG pixel unit 64 and WGB pixel unit 66 .

In addition, the pixel arrangement of the present invention is not limited to using RGB three primary color sub-pixels, but can be any three basic hue sub-pixels that can provide various mixed colors. For example, the color filters used in subtractive color mixing can also be used to form cyan (C), magenta (M) and yellow (Y) sub-pixel arrangements. As shown in FIG. 10 , the CMYW pixel layout is arranged, wherein the pixel units defined according to the present invention are CMY pixel unit 70 , MYW pixel unit 72 , YWC pixel unit 74 , and WCM pixel unit 76 . Moreover, the color of the W sub-pixel of the present invention is not limited to white, but only needs to be a mixed color formed by mixing at least two of the three primary colors of red (R), green (G) and blue (B), so as to effectively improve the brightness That's it.

In addition, although the multi-color processing method of the present invention is combined with the pixel layout proposed by the present invention, its color compensation effect is the best, because the color lacking in a defined pixel unit can appear in the four directions of the pixel unit at the same time: up, down, left, and right , but the data processing method of the present invention can also be matched with other pixel layouts according to actual needs. For example, as shown in FIG. 11 , if the existing RGBW layout in FIG. 2A is adopted, and the pixel definition and data processing method of the present invention are used, a color compensation effect of one dimension (left and right) can also be obtained.

The above specific embodiments are only for illustrating the present invention, but not for limiting the present invention.
