Abstract
Description
Display substrate, display panel, and display device Technical Field
[0001] The present disclosure relates to the field of semiconductor technology, and in particular to a display substrate, a display panel, and a display device. Background Art
[0002] As shown in Figure 1A, a single-gate structure corresponds to one gate line for each row of pixels, and one data line for each column of pixels. Compared to a single-gate structure, a dual-gate product, shown in Figure 1B, reduces the number of source ICs by increasing the number of gate lines and reducing the number of data lines, thereby lowering costs. For example, a product with a resolution of 1280*480 has 480 gate lines and 1280*3 = 3840 data lines. A mainstream IC has 1920 channels, requiring two source ICs to drive the entire panel. Using dual-gate technology, however, the number of gate lines is 480*2 = 960. Because gate drivers typically utilize gate-on-array (GOA) technology, increasing the number of gate lines does not increase the number of gate ICs. The number of data lines is 1280*3 / 2 = 1920, requiring only one IC.

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. It should be noted that the sizes and shapes of the figures in the drawings do not reflect the actual proportions, and the purpose is only to illustrate the contents of the present invention. And the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0066] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in the specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "upper", "lower" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0067] As used herein, "about" or "approximately the same" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "approximately the same" can mean that the difference relative to the stated value is within one or more standard deviations, or within ±30%, 20%, 10%, 5%.
[0068] In the accompanying drawings, the thickness of layers, films, panels, regions, etc. are exaggerated for clarity. Exemplary embodiments are described herein with reference to cross-sectional views that are schematic representations of idealized embodiments. As such, deviations from the shapes of the figures are to be expected as a result of, for example, manufacturing techniques and / or tolerances. Thus, the embodiments described herein should not be construed as limited to the specific shapes of the regions as shown herein, but rather include deviations in shape that result from, for example, manufacturing. For example, a region illustrated or described as flat may typically have rough and / or nonlinear features. Furthermore, sharp corners illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.
[0069] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.
[0070] In the existing dual-gate pixel architecture, when column inversion is used, mixed color patterns and special patterns (for example, a pure green screen) result in differences in charging between different columns, resulting in vertical streak defects. Specifically, as shown in FIG2A , in a yellow pattern of red and green mixed colors, the sub-pixels corresponding to the red and green colors are bright, while the blue sub-pixel is dark. In FIG2A , columns D1, D2, D4, and D5 are bright, while columns D3 and D6 are dark. When column inversion is used, the data voltages corresponding to columns D1 and D2 are DC, resulting in stronger charging of columns D1 and D2. Since column D3 is dark and column D4 is bright, the data voltage connecting columns D3 and D4 is AC, resulting in a lower charging rate of column D4 than that of column D1. Similarly, the charging rate of column D5 is lower than that of column D2. At low temperatures, this difference is amplified, making vertical streak defects more likely to occur. Specifically, as shown in Figures 2B to 2D, for a monochrome image, such as a red image, spatially: within the same frame, the polarity of each red pixel column is +-+- periodic, and the brightness of adjacent polarities of +- can be averaged, while the brightness of adjacent polarities of ++ or - cannot be averaged, and the polarity needs to be flipped in the next frame or averaged by the brightness of two frames; temporally: during continuous observation, the polarity of each frame is reversed, and the brightness of each column between adjacent frames can be averaged by superimposing itself, but when the head moves, frames may be lost, resulting in the two columns that cannot be averaged in space losing the time averaging effect, resulting in periodic vertical stripes, called head shaking stripes. In order to alleviate the vertical stripe defect, 2-subpixel (dot) inversion is usually used, as shown in Figure 2E, but 2-dot inversion consumes very high power. In order to use column inversion, a dual gate Z architecture is proposed, as shown in Figure 3. The data line of this architecture needs to go around to the adjacent subpixels, reducing the aperture ratio of the pixel.
[0071] Therefore, it is urgently necessary for those skilled in the art to propose a dual gate pixel structure that can use column inversion, avoid charging differences between different columns, and not reduce the aperture ratio.
[0072] In view of this, referring to FIG. 4 and FIG. 7A-FIG , where FIG. 7B is a schematic diagram of a single film layer of the gate line in FIG. 7A , FIG. 7B is a schematic diagram of a single film layer of the gate line in FIG. 7A ; FIG. 7C is a schematic diagram of a single film layer of the active layer in FIG. 7A ; FIG. 7D is a schematic diagram of a single film layer of the data line in FIG. 7A ; FIG. 7E is a schematic diagram of a single film layer of the planar layer in FIG. 7A ; FIG. 7F is a schematic diagram of a single film layer of the pixel electrode layer in FIG. 7A ; and FIG. 7G is a schematic diagram of a single film layer of the common electrode layer in FIG. 7A , an embodiment of the present disclosure provides a display substrate, comprising:
[0073] Base substrate 1;
[0074] A plurality of gate line groups 20 are located on one side of the base substrate 1 and extend along a first direction X. At least one gate line group 20 of the plurality of gate line groups 20 includes two gate lines 2 extending along the first direction X.
[0075] A plurality of data lines 3 are located on the same side of the base substrate 1 as the gate lines 2 and extend along the second direction Y. The plurality of data lines 3 include: first-type data lines 31 and second-type data lines 32 alternately arranged along the first direction X.
[0076] a plurality of transistors T located in an area formed by the intersection of the gate line group 20 and the data line 3, the plurality of transistors T including: a sub-transistor group T1 located between adjacent gate line groups 20 and arranged along the first direction X, the sub-transistor group T1 including two transistors T, the transistors T in the same sub-transistor group T1 being connected to the same gate line 2, the transistors T in adjacent sub-transistor groups T1 being connected to different gate lines 2, and the transistors T in the same sub-transistor group T1 being connected to different data lines 3; that is, two adjacent transistors T connected to the same gate line 2 can be considered as one sub-transistor group T1;
[0077] Multiple pins 4 are located on the same side of the base substrate 1 as the gate lines 2. The multiple pins 4 include first-type pins 41 and second-type pins 42 arranged alternately along the first direction X. Two adjacent first-type data lines 31 are connected to a first-type pin 41, and adjacent second-type data lines 32 are connected to a second-type pin 42. Specifically, the signals loaded on the first-type pins 41 and the second-type pins 42 have opposite polarities, and column inversion is performed between adjacent frames.
[0078] Specifically, for the display substrate provided by the embodiment of the present disclosure, when a pure grayscale pattern is displayed, as shown in FIG4 , the signal loaded on the first type pin 41 is positive polarity, and the signal loaded on the second type pin 42 is negative polarity. Within one frame, the signal loaded on the first type pin 41 and the signal loaded on the second type pin 42 are both DC, and the charging degree of all pixel columns is the same, there is no charging difference between different columns, and the polarities of adjacent sub-pixels are opposite. For example, in a certain frame, the signal loaded on the first type pin 41 is positive polarity, and the signal loaded on the second type pin 42 is negative polarity. The pixel electrode of sub-pixel A is charged with a positive voltage signal, and the surrounding sub-pixels B, C, D, The negative voltage signal of the second type of pin 42 for equal charging of sub-pixel E, the pixel voltage of sub-pixel A pulls the voltage loaded on the common electrode (com) in a positive direction, and the voltages of the surrounding sub-pixels pull com in a negative direction. Since the pulling directions are opposite, the pulling on the common electrode loaded voltage is offset, which is beneficial to improving flicker and afterimage (if the pulling on the common electrode loaded voltage cannot be offset, the common electrode loaded voltage deviates from the center point after being pulled, the brightness difference between the positive and negative frames is large, and the flick is aggravated; at the same time, after the common electrode loaded voltage is pulled away from the center point, the DC bias in the display box is aggravated, resulting in an increased severity of the afterimage).
[0079] Specifically, for the display substrate provided by the embodiment of the present disclosure, when a pure color image is displayed, such as a pure green image, as shown in FIG5 , the signal loaded by the first type pin 41 is positive polarity, and the signal loaded by the second type pin 42 is negative polarity, both of which are column inversions. The voltage of the data line 3 is a DC signal within one frame, and the charging rate of all positive polarity green sub-pixels is the same, and the charging rate of all negative polarity green sub-pixels is the same. Therefore, there is no charging difference between different columns of the pure color pattern, and there is no vertical streak defect. Moreover, the polarities of adjacent green sub-pixels are opposite, and the pull of the pixel electrode (pixel) voltage on the voltage loaded on the common electrode (com) can be offset, which is beneficial to improve Flick and afterimage.
[0080] Specifically, for the display substrate provided by the embodiment of the present disclosure, when a mixed color pattern is displayed, for example, a yellow pattern of red and green mixed colors, as shown in Figure 6, the sub-pixels corresponding to the red pixel column and the green pixel column are bright, and the blue pixel column is not bright. Using the display substrate and pixel driving method provided by the embodiment of the present disclosure, the data voltages corresponding to the red and green sub-pixels in the mixed color pattern are both AC signals, and there is no difference in charging of different sub-pixels. Therefore, the vertical stripe defect existing in the existing dual gate pixels is fundamentally solved.
[0081] As described above, the display substrate and driving method provided by the embodiments of the present disclosure have no charging differences when displaying pure grayscale patterns (i.e., yellow, green, and blue sub-pixels are all bright), pure color patterns, mixed color patterns, etc., thereby improving vertical streak defects; at the same time, the use of a column inversion method greatly reduces the power consumption of the display substrate; that is, the number of data lines is reduced by increasing the number of gate lines, which has the same purpose as conventional dual gate products, and can reduce the number of ICs, thereby reducing costs, and at the same time can improve the limitation of existing dual gate pixels that cannot use column inversion, thereby greatly reducing power consumption; column inversion can be achieved using non-Z-shaped winding, and the aperture ratio is increased by 8% to 10%; in addition, the pixel voltages of adjacent sub-pixels pull the common electrode load voltage in opposite directions, and the pulls cancel each other out, which is beneficial to improving flicker and afterimage problems.
[0082] Specifically, as shown in Figures 7A to 7G , the data line 3 can be located on the side of the gate line 2 facing away from the base substrate 1. A pixel electrode layer 8 can be further provided on the side of the data line 3 facing away from the gate line 2. A common electrode layer 6 can also be provided on the side of the pixel electrode layer 8 facing away from the data line 3. Specifically, the pixel electrodes of the pixel electrode layer 8 can be block-shaped, and the common electrode layer 6 can be a comb-shaped structure with slits.
[0083] In a possible implementation, as shown in FIG4 to FIG6 , the gate line group 20 includes: a first gate line 21 and a second gate line 22 ;
[0084] The plurality of transistors T include: a first transistor row T100 and a second transistor row T200 extending along a first direction X and alternately arranged along a second direction Y; the sub-transistor group T1 includes: a first sub-transistor group T11 and a second sub-transistor group T12 alternately arranged along the first direction X;
[0085] In the first transistor row T100, the transistors T in the first sub-transistor group T11 are connected to the first gate line 21, and the transistors T in the second sub-transistor group T12 are connected to the second gate line 22. In the second transistor row T200, the transistors T in the first sub-transistor group T11 are connected to the second gate line 22, and the transistors T in the second sub-transistor group T12 are connected to the first gate line 21. Moreover, two adjacent transistors T in the same column of transistors T are connected to different data lines 3.

[0105] The display panel provided by the embodiments of the present disclosure is suitable for advanced dimension switch (ADS) liquid crystal displays, high-aperture ratio advanced dimension switch (HADS) liquid crystal displays, and twisted nematic (TN) liquid crystal displays. It is applicable not only to a-Si transistor products, but also to products using oxide transistors and low-temperature polysilicon transistors.
[0106] Based on the same inventive concept, the embodiment of the present disclosure also provides a display device, which includes a display panel as provided in the embodiment of the present disclosure. The display device can be: a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, a smart watch, a fitness wristband, a personal digital assistant, or any other product or component with a display function. Other essential components of the display device should be understood by those of ordinary skill in the art, and will not be described in detail here, nor should they be used as limitations on the present invention. In addition, since the principle of solving the problem by the display device is similar to the principle of solving the problem by the above-mentioned display panel, the implementation of the display device can refer to the embodiment of the above-mentioned liquid crystal display panel, and the repeated parts will not be described in detail.
[0107] Based on the same inventive concept, the embodiment of the present disclosure further provides a driving method of the display substrate provided in the embodiment of the present disclosure, as shown in FIG10 , wherein the driving method includes:
[0108] Step S100: When displaying an image in the Nth frame, a first-type signal is applied to a first-type pin, and a second-type signal is applied to a second-type pin, wherein the polarity of the first-type signal is opposite to that of the second-type signal, where N is an integer; specifically, for example, the first-type signal is a positive polarity signal and the second-type signal is a negative polarity signal;
[0109] Step S200 : When displaying an image in the N+1th frame, the second type of signal is loaded to the first type of pins, and the first type of signal is loaded to the second type of pins.
[0110] The display substrate and driving method provided by the embodiments of the present disclosure have no charging differences when displaying pure grayscale patterns (i.e., yellow, green, and blue sub-pixels are all bright), pure color patterns, mixed color patterns, etc., thereby improving vertical streak defects. Furthermore, the use of a column inversion method greatly reduces the power consumption of the display substrate. That is, the number of data lines is reduced by increasing the number of gate lines, which has the same purpose as conventional dual gate products. Both can reduce the number of ICs, thus reducing costs. It can also overcome the limitation of existing dual gate pixels that cannot use column inversion, greatly reducing power consumption. Column inversion can be achieved using non-Z-shaped windings, increasing the aperture ratio by 8% to 10%. In addition, the pixel voltages of adjacent sub-pixels pull the common electrode load voltage in opposite directions, and the pulls cancel each other out, which helps to improve flicker and afterimage problems.
[0111] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0112] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if such changes and modifications of the embodiments of the present invention fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
