In an embodiment, refer to
a plurality of scan lines and a plurality of data lines, the scan lines and the data lines are staggered to define pixels arranged in an array; and
each of the data lines is connected to pixels of a same color.
The present embodiment provides a pixel driving structure. A same one of the data lines is only connected to pixels of one color, while an image of a single color or a double-color mixed color is showed by driving the pixel driving structure, driving voltages on the data lines are at continuous high potentials, so that showing the image of the single color or the double-color mixed color is a light-load operation. In this case, ability of charging the pixels is strong, effectively reducing a risk of poor image display caused by insufficient charging of the pixels. Furthermore, each of the data lines only charges pixels of one color, and the driving voltages on the data lines are at continuous high potentials, preventing a problem of mischarging the pixels and preventing color deviation caused by the mischarging, which eventually causes a problem of poor image display. Therefore, display effects of a display panel are greatly improved.
In the pixel driving structure provided by the embodiment of the present application, the pixels may include pixels of three different colors, such as red pixels R, green pixels G, and blue pixels B. The pixels may also include pixels of four different colors, such as red pixels R, green pixels G, blue pixels B, and white pixels W. The pixels may further include pixels of other colors. In the following specific embodiments, pixels including red pixels R, green pixels G, and blue pixels B are taken as examples to describe the pixel driving structures provided by the embodiments of the present application.
In a first embodiment, refer to
Each one of the scan lines is connected to a row of pixels adjacent to it. For example, a first scan line G1 is connected to a first row of pixels, a second scan line G2 is connected to a second row of pixels, etc. Each one of the data lines is simultaneously connected to pixels of a same color among three continuous columns of pixels adjacent to it.
As shown in
Further, different data lines are connected to red pixels R, green pixels G, and blue pixels B in an alternating way. For example, a fourth data line D4 is connected to all red pixels disposed in the fourth column of pixels, the fifth column of pixels, and a sixth column of pixels, a fifth data line D5 is connected to all green pixels disposed in the fifth column of pixels, the sixth column of pixels, and a seventh column of pixels, a sixth data line D6 is connected to all blue pixels disposed in the sixth column of pixels, the seventh column of pixels, and an eighth column of pixels, and so on. That is, all (3s+1)th data lines are connected to red pixels R, all (3s+2)th data lines are connected to green pixels G, and all (3s+3)th data lines are connected to blue pixels B, where s is a positive integer.
In the pixel driving structure provided by the present embodiment, each data line is connected to pixels of a same color among three continuous columns of pixels located at a right side of the data line and adjacent to the data line. While an image of a single color or a double-color mixed color is showed by driving the pixel driving structure, driving voltages on the data lines are at continuous high potentials, so that showing the image of the single color or the double-color mixed color is a light-load operation. In this case, ability of charging the pixels is strong, effectively reducing a risk of poor image display caused by insufficient charging of the pixels. Furthermore, each of the data lines only charges pixels of one color, and the driving voltages on the data lines are at continuous high potentials, preventing a problem of mischarging the pixels and preventing color deviation which is caused by the mischarging, which eventually causes a problem of poor image display. Therefore, display effects of a display panel are greatly improved.
As shown in
In order to solve this problem, in a first scheme, the first column of pixels and the second column of pixels are set as columns of dummy pixels, that is, all of the first column of pixels and the second column of pixels, including red pixels R, green pixels G, and blue pixels B, do not emit light, thereby preventing a problem of color deviation caused by uneven light mixing performed on the first column of pixels and the second column of pixels.
In a second scheme, the second data line D2 is further connected to green pixels G disposed in the first column of pixels that are located at a left side of the second data line D2 for transmitting data voltage signals to all green pixels G disposed in the first column of pixels, so that all of the green pixels G disposed in the first column of pixels may normally emit light for display. The third data line D3 is further connected to blue pixels B disposed in the first column of pixels and the second column of pixels that are located at a left side of the third data line D3 for transmitting data voltage signals to all blue pixels B disposed in the first column of pixels and the second column of pixels, so that all of the blue pixels B disposed in the first column of pixels and the second column of pixels may normally emit light for display. Therefore, a problem that the green pixels G disposed in the first column of pixels and the blue pixels B disposed in the first column of pixels and the second column of pixels are unable to emit light, and the problem of color deviation caused by unnormal light mixing performed on the first column of pixels and the second column of pixels are prevented.
In a second embodiment, refer to
In the pixel driving structure provided by the present embodiment, each one of the data lines is connected to pixels of a same color among three continuous columns of pixels located at a left side of the each one of the data lines and adjacent to the each one of the data lines. While an image of a single color or a double-color mixed color is showed by driving the pixel driving structure, driving voltages on the data lines are at continuous high potentials, so that showing the image of the single color or the double-color mixed color is a light-load operation. In this case, ability of charging the pixels is strong, effectively reducing a risk of poor image display caused by insufficient charging of the pixels. Furthermore, each of the data lines only charges pixels of one color, and the driving voltages on the data lines are at continuous high potentials, preventing a problem of mischarging the pixels and preventing color deviation caused by the mischarging, which eventually causes a problem of poor image display. Therefore, display effects of a display panel are greatly improved.

A (k−2)th data line D(k−2) is further connected to red pixels R disposed in the kth column of pixels and the (k−1)th column of pixels that are located at a right side of the (k−2)th data line D(k−2) for transmitting data voltage signals to all red pixels R disposed in the kth column of pixels and the (k−1)th column of pixels, so that the red pixels R disposed in the kth column of pixels and the (k−1)th column of pixels may normally emit light for display. Therefore, a problem that the green pixels G disposed in the k column of pixels and the red pixels R disposed in the kth column of pixels and the (k−1)th column of pixels are unable to emit light, and a problem of color deviation caused by unnormal light mixing performed on the kth column of pixels and the (k−1)th column of pixels are prevented.

While an image of a single color or a double-color mixed color is showed by driving the pixel driving structure, driving voltages on the data lines are at continuous high potentials, so that showing the image of the single color or the double-color mixed color is a light-load operation. In this case, ability of charging the pixels is strong, effectively reducing a risk of poor image display caused by insufficient charging of the pixels. Furthermore, each of the data lines only charges pixels of one color, and the driving voltages on the data lines are at continuous high potentials, preventing a problem of mischarging the pixels and preventing color deviation caused by the mischarging, which eventually causes a problem of poor image display. Therefore, display effects of a display panel are greatly improved.
