Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the display substrate and the display panel provided in the present invention in detail with reference to the accompanying drawings.
Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but which may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Embodiments of the invention and features of the embodiments may be combined with each other without conflict.
As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The embodiments described herein may be described with reference to plan and/or cross-sectional views in idealized representations of the present invention. Accordingly, the example illustrations may be modified in accordance with manufacturing techniques and/or tolerances. Accordingly, the embodiments are not limited to the embodiments shown in the drawings, but include modifications of configurations formed based on a manufacturing process. Thus, the regions illustrated in the figures have schematic properties, and the shapes of the regions shown in the figures illustrate specific shapes of regions of elements, but are not intended to be limiting.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
In the related art, there are various causes of the afterimage phenomenon, and the inventors of the present invention found the cause related to the rubbing alignment process by microscopic analysis of the cause of the afterimage formation. In microscopic analysis of the cause of the formation of the afterimage, the inventors found that a phenomenon in which the liquid crystal deflection is slow occurs on the long side of the pixel, such as the green pixel changing slowly from L255 (full bright state) to L0 (full black state) to the full black state on the long side.
Further analyzing the image sticking defect, it is found that the main reason for the defect is that when the Shielding Bar (Shielding Bar) of the pixel unit crosses the data line, the height difference between the film layer at the crossing position and the film layer at the non-crossing position is too large. As shown in fig. 1, on the array substrate, a gate insulating film (GI) covers over the shield strips, a Data line (Data) covers over the GI, a passivation film (PVX) covers over the Data and the GI, and an orientation film (PI) covers over the PVX film. Since the film layer at the crossing position covers the crossing part of the data line and the shielding strip at the same time, the height difference is the sum of the thicknesses of the film layers of the data line and the shielding strip. Since the alignment layer has no leveling function, when a subsequent Rubbing alignment process (Rubbing) is performed, the Rubbing applied to the alignment layer at a lower height is small due to the height difference, and a Rubbing weak region is formed, so that the alignment capability of the alignment layer is weakened, and thus, the liquid crystal is slowly deflected and a residual image is generated.
As shown in fig. 2, in order to shield an electric field and protect light leakage, a shielding bar is disposed at a position close to the data line 11 and the gate line 12. There is a first shield strip 141 in the pixel unit 131 and a second shield strip 142 in the pixel unit 132, which are connected to each other between the pixel units through an intermediate crossover 151, passing a Common (Common) electrode signal, and the width of the crossover in the middle of the shield strips is generally wide in order to ensure the uniformity of the Common voltage. Although the black matrix has a certain range of shielding in the directions of the gate lines 12 and the data lines 11, the black matrix cannot completely shield all the areas where the liquid crystal is slowly deflected because the friction weak area is caused by the height difference.
In view of this, as a first aspect of the present invention, there is provided a display substrate, the display substrate includes a plurality of gate lines 12, a plurality of data lines 11, and a plurality of shielding structures, the plurality of gate lines 12 and the plurality of data lines 11 are interleaved to divide the display substrate into a plurality of pixel units, the shielding structures include first shielding strips 141 and second shielding strips 142, the shielding structures are arranged in a plurality of rows and a plurality of columns, each column of shielding structures corresponds to one data line 11, the shielding structures and the data lines 11 are located in different layers, the shielding structures further include at least one bridging portion electrically connecting the first shielding strips 141 and the second shielding strips 142, the first shielding strips 141 and the second shielding strips 142 are respectively located at two sides of the corresponding data lines 11, and the shielding structures are configured such that: in a portion between both ends of the shield structure in the direction of the data line 11, a region affected by the bridge does not exceed a predetermined area.
It should be noted that the region affected by the bridge is not equivalent to the above-described friction weakened region. Due to the existence of the black matrix in the display substrate, part of the friction weak area can be shielded by the black matrix in the direction of the grid line 12 and the direction of the data line 11, the display effect of the pixel opening area can not be influenced, and poor afterimage can not be caused.
The idea of the invention is therefore to solve the problem of how to reduce the area of the region affected by the bridge. On one hand, the position of the bridging part can be adjusted, so that a friction weak area caused by the bridging part is more shielded by a black matrix, and the area of an area affected by the bridging part is reduced; on the other hand, the width of the bridging part can be reduced, so that the area of the region affected by the bridging part is reduced.
The area of the area affected by the bridging part is preset for each bridging part, and the area affected by the bridging part is controlled within a preset area range, so that the phenomenon of poor afterimage is improved or eliminated. The predetermined area may be an area previously set according to the size specification of the shielding strip or the pixel unit, an area previously set by comprehensively considering the size specification of the black matrix or the pixel opening area, or an area proportional relationship previously set according to the size specification of the pixel unit.
In some embodiments, the bridge portion includes a first bridge portion 152, and the first bridge portion 152 electrically connects the first shield strip 141 and the second shield strip 142 at one end of the shield structure along the data line 11 direction.
As shown in fig. 6, the position of the bridging portion is moved from the middle position of the first and second shield strips 141 and 142 to one end of the first and second shield strips 141 and 142 in the direction of the data line 11. Such as the first bridge 152 in fig. 3 and 4.
Because based on the analysis result of the poor image sticking, the most serious position of the weak friction area is just at the bridging position of the shielding strip bridging part and the data line 11 in the middle of the pixel (the cross-sectional view of the bridging position is shown in fig. 1), the bridging part position is arranged at the middle of the two ends of the pixel unit shielding strip along the data line 11, so that the weak friction area generated in the rubbing alignment process is closer to the black matrix area in the direction of the grid line 12, more black matrixes can shield the weak friction area, the influence range on the pixel opening area is reduced, and the poor image sticking is further improved or eliminated.
Further, the bridge portion further includes a second bridge portion that electrically connects the first shield strip 141 and the second shield strip 142 at the other end of the shield structure in the direction of the data line 11.
As shown in fig. 5, compared to fig. 2, the position of the bridging portion is shifted from the middle position of the first and second shield strips 141 and 142 to both ends of the first and second shield strips 141 and 142 in the direction of the data line 11.
The principle is that the friction weak area is closer to the black matrix area in the direction of the grid line 12, the influence range on the pixel opening area is reduced, and therefore poor afterimage is improved or eliminated. On this basis, compared with the above-mentioned arrangement of the bridge portion at one end of the first and second shield strips 141 and 142 in the direction of the data line 11, the total width of the bridge portion is increased, and the uniformity and stability of the Common (Common) voltage can be better ensured.
Further, the widths of the first bridge portion 152 and the second bridge portion 153 are smaller than the width of the first shielding strip 141; and/or the widths of the first bridge portions 152 and the second bridge portions 153 are smaller than the width of the second shielding strip 142.
This embodiment can be regarded as that the shielding strip is changed from the "H" shape of fig. 2 to the "mouth" shape of fig. 5, and the number of the bridging portions is increased from one to two (or even more), so that the width of a single bridging portion can be reduced, the area of the friction weak area affected by the bridging portion can be further reduced, and the afterimage can be improved.
In the position change, the shielding strips are connected with each other through the bridging parts among the pixel units, the voltage is the common voltage, in order to ensure the uniformity of the common voltage, the width of the middle part of the H-shaped shielding strip is generally wider, the opening shape changes the wider part of the middle part of the H-shaped shielding strip into two narrower parts, on the premise of ensuring the uniformity of the common voltage, the size of a friction weak area is reduced, and the effect of improving or eliminating the bad afterimage is achieved.
In some embodiments, the bridge portion includes at least one intermediate bridge portion, and a width of each intermediate bridge portion is smaller than a width of any one of the first shield strip 141 and the second shield strip 142.
According to the requirement of the pixel unit on the bridging position of the shielding strips in different scenes, the bridging part can still be kept at the middle position of the first shielding strip 141 and the second shielding strip 142 shown in fig. 2. By reducing the width of the intermediate crossover so as to be smaller than the width of either one of the first shield strip 141 and the second shield strip 142, the area of the friction weak region affected by the crossover is reduced.
Since there is a block of the black matrix region in the data line 11 direction, the block effect in the data line 11 direction is relatively weak because the width of the black matrix region in the data line 11 direction is generally narrower than that in the gate line 12 direction. Because the bridging portion is perpendicular to the direction of the data line 11, the weak friction area perpendicular to the direction of the data line 11 may be shielded by the black matrix area in the direction of the data line 11, and the weak friction area parallel to the direction of the data line 11 may not be completely shielded by the black matrix area to form an area affected by the bridging portion, therefore, the width of the bridging portion is reduced, that is, the weak friction area parallel to the direction of the data line 11 is reduced, the area affected by the bridging portion is reduced, and the effect of improving or eliminating the poor afterimage can be achieved.
In some embodiments, the first shield stripe 141 includes a first transverse stripe extending in a direction identical to the direction of the gate line 12 and a first longitudinal stripe extending in a direction identical to the direction of the data line 11, the first transverse stripe being formed at one end of the first longitudinal stripe;
the second shield stripe 142 includes a second transverse stripe extending in the same direction as the gate line 12 and a second longitudinal stripe extending in the same direction as the data line 11, the second transverse stripe being formed at one end of the second longitudinal stripe.
Further, the first transverse stripe is formed at one end of the first longitudinal stripe in the direction of the data line 11; the second transverse stripe is formed at the other end of the second longitudinal stripe in the direction of the data line 11.
Further, the bridge is electrically connected with the first longitudinal strip and the second longitudinal strip.
As described above, the shielding bars function to shield the electric field and protect the light leakage. Therefore, in some embodiments, each data line 11 controls two columns of pixel units, and taking fig. 5 as an example, the shape of the first shielding strip 141 may be composed of a first transverse strip and a first longitudinal strip, the first transverse strip shields the influence of the electric field of the unrelated adjacent gate line 12, and the first longitudinal strip shields the influence of the electric field of the adjacent data line 11. In other embodiments, it is also possible that each data line 11 controls two columns of pixel units, that is, there are adjacent data lines 11 on both left and right sides of each pixel unit, and then the first shielding strip 141 may have a first longitudinal strip on both sides along the direction of the data line 11 to shield the influence of the electric field of the two data lines 11. The second shielding strips 142 are similar and will not be described herein.
In some embodiments, the display substrate further includes an alignment layer having a height difference between a portion covered with a bridge portion and a portion not covered with the bridge portion, and a region affected by the height difference is used as the region affected by the bridge portion in a portion between both ends of the shielding structure in the data line 11 direction, so that the region affected by the bridge portion does not exceed a predetermined area.
It is to be noted that the determination of the area affected by the cross-over by the area of the friction weakening of the orientation layer affected by the height difference is only a representation of the present invention. Besides, the area affected by the bridging portion may be determined by the ranges of the pixel opening area and the weak rubbing area, or by introducing a factor such as an angle between the rubbing direction and the direction of the data line 11. In this embodiment, based on the height difference between the portion of the alignment layer covered with the bridge portion and the portion not covered with the bridge portion, the area affected by the height difference is taken as the area affected by the bridge portion, and the area affected by the bridge portion is controlled, which is only a preferred embodiment and should not be construed as being limited to this embodiment.
In a second aspect, an embodiment of the present invention provides a display panel, where the display substrate is the display substrate according to the first aspect.
According to the display substrate provided by the invention, the area of the area affected by the bridging part between the two ends of the shielding structure along the direction of the data line is reduced, for example, the bridging part position is arranged at one end or two ends of the shielding structure along the direction of the data line, so that the affected area is more shielded by the black matrix, and the area of the area affected by the bridging part is reduced; or the width of the bridging part is reduced, so that the area of an area affected by the bridging part is reduced, the influence of a slow liquid crystal deflection area on a pixel opening area is further reduced, the bad afterimage in the field of liquid crystal display is improved and eliminated on the premise of not affecting the display quality and not increasing the process or the cost, and the display effect is obviously improved.

In some instances, features, characteristics and/or elements described in connection with a particular embodiment may be used alone or in combination with features, characteristics and/or elements described in connection with other embodiments, unless expressly stated otherwise, as would be apparent to one skilled in the art.
