     The display panel of the present invention includes an array substrate which comprising data lines, scan lines, and a plurality of pixel units defined by intersecting the data lines and the scan lines. The pixel unit comprises: a red pixel, a green pixel, and a blue pixel (for example, RGB). The pixel unit can also include a yellow pixel or a white pixel. The present invention only takes a pixel unit arranged in the order of red pixel, green pixel, and blue pixel (RGB) for an example, but it is not limited thereto. For instance, the pixel unit may further include other arrangements like: a blue pixel, a red pixel, and a green pixel (BRG) arranged in sequence. 
     As shown in  FIG. 1 , the red pixel is divided into four red sub-pixels R 1 , R 2 , R 3 , and R 4 , the red sub-pixels are arranged in a 2×2 matrix (the red sub-pixel R 1  is arranged at a zero row and a zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 2  is arranged at the zero row and a first column of the 2×2 matrix of the red pixel, the red sub-pixel R 3  is arranged at a first row and the zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 4  is arranged at the first row and the first column of the 2×2 matrix of the red pixel). 
     The green pixel is divided into four green sub-pixels G 1 , G 2 , G 3 , and G 4 , the green sub-pixels are arranged in a 2×2 matrix (a matrix of the four green sub-pixels is the same as the four red sub-pixels as described above, and will not be enumerated herein). 
     The blue pixel is divided into four blue sub-pixels B 1 , B 2 , B 3 , and B 4 , the four blue sub-pixels are arranged in a 2×2 matrix (a matrix configuration of the four blue sub-pixels is the same as the four red sub-pixels as described above, and will not be enumerated herein). 
     Of course, the above matrix configurations can also be arranged in other matrix configurations (for example, the red sub-pixel R 1  is arranged at the zero row and the zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 2  is arranged at the first row and the zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 3  is arranged at the zero column and the first column of the 2×2 matrix of the red pixel, the red sub-pixel R 4  is arranged at the first row and the first column of the 2×2 matrix of the red pixel), which are within the scope of the present invention, and will not to be enumerated herein.

The sub-pixels of the pixel unit can also be arranged in other matrix configurations (such as 6×2 matrix), which are within the scope of the present invention, and will not be enumerated herein. 
     In the present invention, when the display panel displays a first 2D image, the first 2D image comprises a plurality of display pixels; the first 2D image is a high-definition 2D image (such as 4K image); each of the sub-pixel units in the pixel unit receives data signals and scan signals of different display pixels. 
     Since in the conventional technology, when displaying a high-definition 2D image, the sub-pixels which are located in odd rows of the pixel unit are arranged in a sequence of R 1 G 1 B 1 R 2 G 2 B 2 , such that different colored sub-pixels are disposed adjacent to each other. When displaying the high-definition image, the display picture is not smooth enough under a situation that human eye is not perceived. 
     However, in the present invention, the sub-pixels which are located in odd rows of the pixel unit are arranged in a sequence of, for example R 1 R 2 G 1 G 2 B 1 B 2 , such that the same colored sub-pixels are disposed adjacent to each other in a final display picture (which means that the red sub-pixels are disposed adjacent to each other in the same pixel unit, the green sub-pixels are disposed adjacent to each other in the same pixel unit, and the blue sub-pixels are disposed adjacent to each other in the same pixel unit). Compared with the conventional technology in which different colored sub-pixels are disposed adjacent to each other, by adopting the above configuration the display picture can more smoothly be displayed as a high-definition 2d image. 
     In the conventional technology, the array substrate comprises a gate-driver chip and a source-driver chip, the gate-driver chip is configured to input a scan signal via scan lines to control terminals of TFTs of each pixel in the pixel unit, the gate-driver chip is configured to transmit a data signal via data lines to input terminals of TFTs of each pixel in the pixel unit. When the gate-driver chip transmits the scan signal to the pixels of first row, the source-driver chip transmits the data signal to the pixels of the first row. When the gate-driver chip inputs the scan signal to the pixels of second row, the source-driver chip inputs the data signal to the pixels of second row. 
     The preferred embodiment further comprises a driving circuit shown in  FIG. 4 . Each of the sub-pixels comprises a thin film transistor (TFT). The array substrate further comprises a source-driver chip and a gate-driver chip (not shown in  FIG. 4 ). The gate-driver chip includes a first gate-driver chip  11  and a second gate-driver chip  12 . The source-driver chip includes a first source-driver chip  21  and a second source-driver chip  22 . The first gate-driver chip  11  is configured to input a scan signal via the scan lines to control terminals of TFTs of the sub-pixels located in odd rows (such as R 1 R 2 G 1 G 2 B 1 B 2 ) in the pixel unit. The second gate-driver chip  12  is configured to input a scan signal via the scan lines to control terminals of TFTs of the sub-pixels located in even rows (such as R 3 R 4 G 3 G 4 B 3 B 4 ) in the pixel unit. The first source-driver chip  21  is configured to input a data signal via the data lines to input terminals of TFTs of the sub-pixels located in odd columns (such as R 1 G 1 B 1 R 3 G 3 B 3 ) in the pixel unit; the second source-driver chip  22  is configured to input a data signal via the data lines to input terminals of TFTs of the sub-pixels located in even columns (such as R 2 G 2 B 2 R 4 G 4 B 4 ) in the pixel unit. 
     Only a single gate-driver chip and a single source-driver chip are provided in the conventional technology. In order to display a high-definition 2D image, a more complicated process is needed. The functional requirements of the single gate-driver chip and the single source-driver chip are higher, and the structural design of which is more complicated. By contrast, the present invention only adopts two regular gate-driver chips and two regular source-driver chips to achieve the more complicated processes, thereby reduced the production cost. 
     The display panel is a liquid crystal panel or an active-matrix organic light-emitting diode display panel. 
       FIG. 2  is a schematic diagram of a pixel unit according to a second preferred embodiment of the present invention.

The pixel unit comprises: a red pixel, a green pixel, a blue pixel (for example, RGB). The pixel unit can also include a yellow pixel or a white pixel. The present invention only takes the pixel unit arranged in an order of red pixel, green pixel, and blue pixel (RGB) for an example, but it is not limited to, e.g. the pixel unit may further include other arrangements like: blue pixel, red pixel, and green pixel (BRG). 
     As shown in  FIG. 1 , the red pixel is divided into four red sub-pixels R 1 , R 2 , R 3 , and R 4 , the red sub-pixels are arranged in a 2×2 matrix configuration (the red sub-pixel R 1  is arranged in a zero row and a zero column of a 2×2 matrix of the red pixel, the red sub-pixel R 2  is arranged at the zero row and a first column of the 2×2 matrix of the red pixel, the red sub-pixel R 3  is arranged at a first row and the zero column of a 2×2 matrix of the red pixel, the red sub-pixel R 4  is arranged at the first row and the first column of a 2×2 matrix of the red pixel). 
     The green pixel is divided into four green sub-pixels G 1 , G 2 , G 3 , and G 4 , the green sub-pixels are arranged in a 2×2 matrix (a matrix configuration of the four green sub-pixels is the same as the four red sub-pixels as described above, and will not be enumerated herein). 
     The blue pixel is divided into four blue sub-pixels B 1 , B 2 , B 3 , and B 4 , the four blue sub-pixels are arranged in a 2×2 matrix (a matrix configuration of the four blue sub-pixels is the same as the four red sub-pixels as described above, and will not be enumerated herein). 
     The above matrix configuration can also be arranged into other matrix configurations (for example, the red sub-pixel R 1  is arranged at the zero row and the zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 2  is arranged at the first row and the zero column of the 2×2 matrix of the red pixel, the red sub-pixel R 3  is arranged at the zero column and the first column of the 2×2 matrix of the red pixel, the red sub-pixel R 4  is arranged at the first row and the first column of the 2×2 matrix of the red pixel), which are within the scope of the present invention, and will not be enumerated herein. 
     R 1 G 1 B 1  constitutes a first sub-pixel unit, R 2 G 2 B 2  constitutes a second sub-pixel unit, R 3 G 3 B 3  constitutes a third sub-pixel unit, R 4 G 4 B 4  constitutes a fourth sub-pixel unit, all of the sub-pixels of the pixel unit are arranged in a 2×6 matrix. The sub-pixels of the pixel unit can also be arranged into other matrix configurations (such as a 6×2 matrix), which are within the scope of the present invention, and will not be enumerated herein. 
     In the present invention, when the display panel displays a 3D image, the 3D image comprises a plurality of display pixels. Each of the sub-pixels in the sub-pixel unit are disposed in the same position of the corresponding pixel matrices (for example, in a first sub-pixel unit R 1 G 1 B 1 , a red sub-pixel R 1  is arranged at a zero row and a zero column of a 2×2 matrix of the red pixel, a green sub-pixel G 1  is arranged at a zero row and a zero column of a 2×2 matrix of the green pixel, a blue sub-pixel B 1  is arranged at a zero column and a zero column of a 2×2 matrix of the blue pixel). 
     The sub-pixel units (such as R 1 G 1 B 1  and R 3 G 3 B 3 ) constituted by the sub-pixels located in odd columns in the pixel unit receive the data signals and scan signals of left-eye display pixels or right-eye display pixels, the sub-pixel units (such as R 2 G 2 B 2  and R 4 G 4 B 4 ) constituted by the sub-pixels locating in even columns in the pixel unit receive the data signals and scan signals of right-eye display pixels or right-eye display pixels. 
     When R 1 G 1 B 1  and R 3 G 3 B 3  receive the data signals and the scan signals of the left-eye display images, R 2 G 2 B 2  and R 4 G 4 B 4  receive the data signals and the scan signals of the right-eye display images. In this case, the equivalent structure diagram of the pixel unit is illustrated in  FIG. 2 , wherein the red sub-pixels R 1  and R 3  are equivalent to R 1  (a red left-eye pixel), the green sub-pixels G 1  and G 3  are equivalent to G 1  (a green left-eye pixel), and the blue sub-pixels B 1  and B 3  are equivalent to B 1  (a blue left-eye pixel).

When displaying the 3D image, the display picture is not smooth enough under a situation that human eye is not perceived.

The green sub-pixels are disposed adjacent to each other in the same pixel unit, and the blue sub-pixels are disposed adjacent to each other in the same pixel unit). 
     Compared with the conventional technology in which different colored sub-pixels are disposed adjacent to each other, by adopting the above structure, the display picture can more smoothly be displayed as a 3d image. 
     In the conventional technology, the array substrate comprises a gate-driver chip and a source-driver chip. The gate-driver chip is configured to input a scan signal via scan lines to control terminals of TFT of each pixel in the pixel unit, the gate-driver chip is configured to input a data signal via data lines to the input terminals of TFT of each pixel in the pixel unit. When the gate-driver chip inputs the scan signal to the pixels of first row, the source-driver chip inputs the data signal to the pixels of the first row. When the gate-driver chip inputs the scan signal to the pixels of second row, the source-driver chip inputs the data signal to the pixels of second row.

     The second source-driver chip  22  is configured to input a data signal via the data lines to input terminals of TFT of the sub-pixels located in even columns (such as R 2 G 2 B 2 R 4 G 4 B 4 ) in the pixel unit (the data signals are the data signals of the left-eye display pixels or the right-eye display pixels). When the first source-driver chip  21  inputs a data signal of the left-eye display pixels, the second source-driver chip  22  inputs a data signal of the right-eye display pixels; when the first source-driver chip  21  inputs a data signal of the right-eye display pixels, the second source-driver chip  22  inputs a data signal of the left-eye display pixels.

     Wherein R 1 G 1 B 1  constitutes a first sub-pixel unit, R 2 G 2 B 2  constitutes a second sub-pixel unit, R 3 G 3 B 3  constitutes a third sub-pixel unit, R 4 G 4 B 4  constitutes a fourth sub-pixel unit, all sub-pixels of the pixel unit are arranged in a 2×6 matrix configuration, the sub-pixels of the pixel unit can also be arranged into other matrix configurations (such as 6×2), which are within the scope of the present invention, and will not be enumerated herein. 
     In the present embodiment, when the display panel displays a second 2D image, the second 2D image comprises a plurality of display pixels; the second 2D image is a low-definition 2D image; each of the sub-pixel units in the pixel unit receives a data signal and a scan signal of the same display pixel. In this case, the equivalent diagram of the pixel unit is shown in  FIG. 3 , where all of the red sub-pixels R 1 , R 2 , R 3 , R 4  are equivalent to R (a red pixel), all of the green sub-pixels G 1 , G 2 , G 3 , G 4  are equivalent to G (a green pixel), all of the blue sub-pixels B 1 , B 2 , B 3 , B 4  are equivalent to B (a blue pixel). 
     In the conventional technology, when displaying the low-definition 2D image, the sub-pixels which are located in the odd rows of the pixel unit are arranged in a sequence of R 1 G 1 B 1 R 2 G 2 B 2 , such that different colored sub-pixels are disposed adjacent to each other. However, in the present invention, the sub-pixels which are located in the odd rows of the pixel unit are arranged in a sequence of, for example R 1 R 2 G 1 G 2 B 1 B 2 , such that the same colored sub-pixels are disposed adjacent to each other in a final display picture (which means that the red sub-pixels are disposed adjacent to each other in the same pixel unit, the green sub-pixels are disposed adjacent to each other in the same pixel unit, and the blue sub-pixels are disposed adjacent to each other in the same pixel unit). 
     Compared with the conventional technology in which different colored sub-pixels are disposed adjacent to each other, by adopting the above configuration, an equivalent display effect as the conventional technology can be achieved when displaying the low-definition 2D image. 
     In the conventional technology, the array substrate comprises a gate-driver chip and a source-driver chip. The gate-driver chip is configured to input a scan signal via scan lines to the control terminals of TFTs of each pixel in the pixel unit, the gate-driver chip is configured to input a data signal via data lines to the input terminals of TFTs of each pixel in the pixel unit. When the gate-driver chip inputs the scan signal to the pixels of a first row, the source-driver chip inputs the data signal to the pixels of the first row. When the gate-driver chip inputs the scan signal to the pixels of a second row, the source-driver chip inputs the data signal to the pixels of second row. 
     The preferred embodiment further comprises a driving circuit, which the structure is shown in  FIG. 4 , each of the sub-pixels comprises a thin film transistor (TFT); the array substrate further comprises a source-driver chip and a gate-driver chip: the gate-driver chip includes a first gate-driver chip  11  and a second gate-driver chip  12 ; the source-driver chip includes a first source-driver chip  21  and a second source-driver chip  22 . The first gate-driver chip  11  is configured to input a scan signal via the scan lines to control terminals of TFTs of the sub-pixels located in odd rows (such as R 1 R 2 G 1 G 2 B 1 B 2 ) in the pixel unit; the second gate-driver chip  12  is configured to input a scan signal via the scan lines to control terminals of TFTs of the sub-pixels located in even rows (such as R 3 R 4 G 3 G 4 B 3 B 4 ) in the pixel unit. the first gate-driver chip  11  and the second gate-driver chip  12  of the present invention simultaneously input the same scan signal to the sub-pixels located in even rows and odd rows, respectively. 
     The first source-driver chip  21  is configured to input a data signal via the data lines to the input terminals of TFT of the sub-pixels located in the odd columns (such as R 1 G 1 B 1 R 3 G 3 B 3 ) in the pixel unit; the second source-driver chip  22  is configured to input a data signal via the data lines to the input terminals of TFT of the sub-pixels located in the even columns (such as R 2 G 2 B 2 R 4 G 4 B 4 ) in the pixel unit. 
     The first source-driver chip  21  and the second source-driver chip  22  of the present invention simultaneously input the same data signal to the sub-pixels located in even columns and odd columns, respectively. 
     While the conventional technology only provides a gate-driver chip and a source-driver chip, the present invention adopts two regular gate-driver chips and two regular source-driver chips to achieve the same display effect as the conventional technology when displaying the low-definition 2D images. 
     The display panel is a liquid crystal panel or an active-matrix organic light-emitting diode display panel.
