To make the objective, the technical solution, and the effect of the present invention clearer and more explicit, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention instead of being used to limit the present invention.
An embodiment of the present invention provides a pixel structure comprises: a plurality of pixel units, the pixel units can be arranged in an array. The embodiment of the present invention has no specific limitation to an arrangement thereof.
With reference to
The sub-pixels in each of the pixel units can be divided in three color groups, the sub-pixels of the three color groups are red sub-pixels, green sub-pixels, and blue sub-pixels. Numbers of the red sub-pixels, green sub-pixels, and the blue sub-pixels are equal to one another or different from one another, and the embodiment of the present invention has no limit thereto.
When a display image of a current frame is displayed, the sub-pixels of the same color group are divided in two polarity groups, the sub-pixels of the two polarities are the sub-pixels of the positive polarity and the sub-pixels of the negative polarity respectively, and a number of the sub-pixels of the positive polarity is equal to a number of the sub-pixels of the negative polarity. Namely, the red sub-pixels can be divided in the sub-pixels of the positive polarity and the sub-pixels of the negative polarity equal in number, the green sub-pixels can be divided in the sub-pixels of the positive polarity and the sub-pixels of the negative polarity equal in number, and the blue sub-pixels can be divided in the sub-pixels of the positive polarity and the sub-pixels of the negative polarity equal in number.
In the sub-pixels of the same color group and the same polarity, polarities of data lines in left and right sides of half of the sub-pixels are positive and negative respectively, and polarities of the data lines in left and right sides of another half of the sub-pixels are negative and positive respectively. For example, with reference to
It should be explained that a brightness a of the brightened sub-pixels of the positive polarity, a brightness b of the darkened sub-pixels of the positive polarity, a brightness c of the brightened sub-pixels of the negative polarity, and a brightness d of the darkened sub-pixels of the negative polarity are different from one another.
When a display image of a current frame is displayed, the brightness of the brightened B1 of the positive polarity is a, the brightness of the darkened B2 of the positive polarity is b, the brightness of the darkened of B3 of the negative polarity is d, and the brightness of the brightened B4 of the negative polarity is c. At this time, a sum of brightness of the blue sub-pixels is a+b+c+d when the display image of the current frame is displayed.
When a display image of a next frame is displayed, a brightness of the brightened B1 of the negative polarity is c, a brightness of the darkened B2 of the negative polarity is d, a brightness of the darkened B3 of the positive polarity is b, a brightness of the brightened B4 of the positive polarity is a. At this time, a sum of brightness of the blue sub-pixels is a+b+c+d when the display image of the next frame is displayed. Namely, when the display image switches from a current frame to a next frame, the brightness of the blue sub-pixels in the pixel units keeps unchanged. For the same reason, when the display image switches from the current frame to the next frame, the brightness of the red sub-pixels in the pixel units keeps unchanged, and the brightness of the green sub-pixels also has no changes.
The present invention provides the pixel structure, the display panel with the pixel structure, and the display device with the pixel structure. The pixel structure comprises a plurality of sub-pixels arranged in a horizontal direction. The sub-pixels are divided in the sub-pixels of three colors, the sub-pixels having of same color are divided in two polarity groups, and numbers of the sub-pixels of the two polarities are equal to each other. In the sub-pixels of the same color group and the same polarity, polarities of data lines in left and right sides of half of the sub-pixels are positive and negative respectively, and polarities of the data lines in left and right sides of another half of the sub-pixels are negative and positive respectively, and wherein when a display image is switched from a current frame to a next frame, the polarity of each of the data lines varies oppositely. For the pixel structure, because the sub-pixels of the same color group in the same pixel unit have the sub-pixels of the positive polarity that brighten equally, the sub-pixels of the positive polarity that darken equally, the sub-pixels of the negative polarity that brighten equally, and the sub-pixels of the negative polarity that darken equally, both in a display image of a current frame and a display image of a next frame, therefore the same pixel unit have a constant brightness when switching between the display images of two frames, which prevents a low grayscale flickering phenomenon during switching between the display images of the two frames.

It should be explained that when the sub-pixel is connected to the corresponding data line on the left side, the polarity of the sub-pixel is the same as the polarity of the data line on the left side. When the sub-pixel is connected to the corresponding data line on the right side, the polarity of the sub-pixel is the same as the polarity of the data line on the right side.

In some embodiments, for a pixel unit, adjacent three of the sub-pixels in the pixel unit have different colors. For example, in a pixel unit, the sub-pixels of three colors can be arranged at intervals in a sequence of red, green, and blue, and can also be arranged at intervals in a sequence of blue, green, and red, and the embodiment of the present invention has no limit thereto.
It should be explained that numbers of the sub-pixels of the three color groups in the pixel units in

In some embodiments, pixel structure further comprises: GOA units, each of the GOA unit are connected to the scan lines and is connected to a scan signal into the scan lines connected thereto. It should be explained that the GOA units to which adjacent two rows of the scan lines are connected are the same or different. If the GOA units connected to adjacent two rows of the scan lines are the same, the signals received by the two rows of the scan lines will be the same. If the GOA units connected to adjacent two rows of the scan lines are the different, the signals received by the two rows of the scan lines will be the different.
