The following drawings are only examples for illustrative purposes according to various embodiments disclosed, and are not intended to limit the scope of the present invention.
To make those skilled in the art better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the following description of some embodiments has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit to the precise forms disclosed, and the repeated description is omitted in order to avoid redundancy.
In order to keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known components may be omitted. When any one component of an embodiment of the present disclosure appears in more than one drawing, the component is represented by a same reference numeral in each drawing. Unless otherwise indicated, those skilled in the art can implement based on common technologies or conditions in the art or based on product instructions in a case that specific technologies or conditions are not clearly described in the following embodiments.
The present disclosure provides, inter alia, a display substrate, a display panel and a display device that substantially obviate one or more of the problems due to limitations and disadvantages of the related art. In the present disclosure, by means of designing the arrangement of sub-pixels, in the pixel regions located in a same row, polarities of voltages of any two closest first sub-pixels are opposite, polarities of voltages of any two closest second sub-pixels are opposite, and thus it is capable of effectively solving a problem of difference in pixel brightness due to a difference in positive and negative voltages of two adjacent data lines of a dual gate structure, thereby effectively solving a problem of shake lines of the dual gate structure.
In this embodiment, the first to third sub-pixels may emit red light (R), green light (G) and blue light (B) respectively, and the sub-pixels in a same row may be periodically arranged in a sequence of the first sub-pixel, the second sub-pixel and the third sub-pixel. In addition, each of the sub-pixels located in a same column emits light of a same color, that is, each of the sub-pixels located in the same column is one of the first sub-pixel, the second sub-pixel and the third sub-pixel.
The reason why the above-mentioned thin film transistor liquid crystal display (TFT-LCD) design is prone to generation of shake lines is that spatially, in each row of pixel regions, the polarities of the voltages of all the first sub-pixels are set to a cyclic arrangement of “+−−+(positive, negative, negative, positive)”, the polarities of the voltages of all the second sub-pixels are set to a cyclic arrangement of “++−− (positive, positive, negative, negative)”, and the polarities of the voltages of all the third sub-pixels are set to a cyclic arrangement of “−++− (negative, positive, positive, negative)”, so that for a same type of sub-pixels (e.g., the first sub-pixel) in each row of pixel regions, a probability that the polarities of the voltages of any two adjacent sub-pixels (i.e., any two closest sub-pixels by distance) are identical is approximately equal to 50%. That is, it is difficult to average the polarities of the voltages of the same type of sub-pixels in a same frame of image on a spatial scale without significantly increasing power consumption, and thus streakiness caused by pixel brightness differences easily occur during a display process. In the related art, by averaging the polarities of the voltages of the same type of sub-pixels on a time scale, it is possible to make the display of the same type of sub-pixels more uniform within a time period. However, in this case, when a user moves his head during viewing, several frames of images may be missed, resulting in a worsening of averaging effect of the polarities of the voltages on the time scale and a phenomenon of shake lines. Therefore, the present disclosure provides a pixel arrangement method that ensures the polarities of the voltages of any two adjacent first sub-pixels (e.g., the red sub-pixel) to be opposite and the polarities of the voltages of any two adjacent second sub-pixels (e.g., the green sub-pixel) to be opposite, thereby effectively improving the display effect of the dual gate structure.
In this embodiment, the first to third sub-pixels 1031, 1032, and 1033 may emit red light (R), green light (G), and blue light (B) respectively, and the sub-pixels in a same row may be periodically arranged in a sequence of the first sub-pixel 1031, the second sub-pixel 1032 and the third sub-pixel 1033. In addition, each of the sub-pixels located in a same column emits light of a same color, that is, each of the sub-pixels located in the same column emits light of a same color, that is, each of the sub-pixels located in a same column is one of the first sub-pixel 1031, the second sub-pixel 1032 and the third sub-pixel 1033.
In the pixel regions of a same row, the polarities of the voltages (i.e., the polarity of the voltage of the coupled data line) of any two first sub-pixels 1031 (e.g., the red sub-pixel or the green sub-pixel) adjacent to each other (i.e., closest by distance) are opposite, and the polarities of the voltages (i.e., the voltage polarity of the coupled data line) of any two second sub-pixels 1032 (e.g., the red sub-pixel or the green sub-pixel) adjacent to each other (i.e., closest by distance) are opposite.
In some implementations, polarities of voltages (i.e., the polarity of the voltage of the coupled data line) of any two third sub-pixels 1303 (e.g., the blue sub-pixel) adjacent to each other (i.e., closest by distance) are identical. In some implementations, the polarities of the voltages of the data lines coupled to any two third sub-pixels 1303 (e.g., the blue sub-pixel) adjacent to each other (i.e., closest by distance) are opposite. In some implementations, the polarities of the voltages of the data lines coupled to any two third sub-pixels 1303 (e.g., the blue sub-pixel) adjacent to each other (i.e., closest by distance) of a portion of the third sub-pixels 1303 are identical, and the polarities of the voltages of the data lines coupled to any two third sub-pixels 1303 (e.g., the blue sub-pixel) adjacent to each other (i.e., closest by distance) of the remaining third sub-pixels 1303 are opposite.
In some implementations, the polarities of the voltages of all the first sub-pixels 1301 in a same row of pixel regions are set to a cyclic arrangement of “+−+− (positive, negative, positive, negative)”, the polarities of the voltages of all the second sub-pixels 1302 in this same row of pixel regions are also set to the cyclic arrangement of “+−+− (positive, negative, positive, negative)”, and then the polarities of the voltages of the third sub-pixels 1303 in this same row of pixel regions can only be set to a cyclic arrangement of “++−− (positive, positive, negative, negative)”. Accordingly, the polarities of the voltages of the third sub-pixels 1303 in the row direction cannot be averaged. However, the polarities of the voltages of the first sub-pixels 1301 and the second sub-pixels 1302 in the pixel regions of a same row are averaged, thereby effectively improving the phenomenon of shake lines.
According to embodiments of the present disclosure, those skilled in the art can design correspondingly the types of the sub-pixels according to the actual display effect of the display substrate. Specifically, the sub-pixels may include, for example, the red sub-pixel, the green sub-pixel, the blue sub-pixel, or the red sub-pixel, the green sub-pixel, the blue sub-pixel, a white sub-pixel, etc. In some implementations of the present disclosure, the sub-pixels may only include the red sub-pixel, the green sub-pixel, and the blue sub-pixel. As a result, the display panel can realize color display while simplifying a display control system.
In some implementations, the sub-pixels in a same row of pixel regions may be periodically arranged in a sequence of the red sub-pixel, the blue sub-pixel, the green sub-pixel, the red sub-pixel, the green sub-pixel, the blue sub-pixel, the green sub-pixel, the blue sub-pixel, the red sub-pixel, the green sub-pixel, the red sub-pixel and the blue sub-pixel. That is, the sub-pixels in a same row of pixel regions are cyclically arranged with RBGRGBGBRGRB as a minimum repetition period. This can realize that the polarities of the voltages of any two adjacent red sub-pixels in a same row of pixel regions are opposite, and the polarities of the voltages of any two adjacent green sub-pixels in a same row of pixel regions are opposite, which can effectively reduce a risk of shake lines in the dual gate structure.
In some implementations, the sub-pixels in the a row of pixel regions may be periodically arranged in a sequence of the green sub-pixel, the blue sub-pixel, the red sub-pixel, the green sub-pixel, the red sub-pixel, the blue sub-pixel, the red sub-pixel, the blue sub-pixel, the green sub-pixel, the red sub-pixel, the green sub-pixel and the blue sub-pixel. That is, the sub-pixels in a same row of pixel regions are cyclically arranged with GBRGRBRBGRGB as a minimum repetition period. This can also realize that the polarities of the voltages of any two adjacent green sub-pixels in a same row of pixel region are opposite, and any two adjacent red sub-pixels in a same row of pixel regions are opposite, which can effectively reduce the risk of shake lines in the dual gate structure.
In some implementations, the sub-pixels located in a same column can emit light of a same color, and thus the sub-pixels with the same polarity of the voltage are arranged in the column direction, which facilitates simplification of an electrical control method and display method of each sub-pixel, thereby narrowing the bezel of the display panel including the display substrate described herein.

In the pixel regions of a same row, the polarities of the voltages of the data lines 102 coupled to any two closest first sub-pixels are opposite, and the polarities of the voltages of the data lines 102 coupled to any two closest second sub-pixels in the pixel regions of a same row are opposite.
