Embodiments of the present disclosure relate to a display panel and a display device.
In a process of the preparation of a liquid crystal panel, a color filter substrate and an array substrate are cell-assembled together to obtain a display panel to implement the preliminary configuration, after cell-assembling the display panel still needs undergo the processes of modifying, plating, polishing and so on. However, in the processes such as the preparation process after cell-assembling, the later process of transportation of display panels and the like, a relative displacement is easy to occur between the edge area of a color filter substrate and the edge area of an array substrate, it is easy to cause some friction between a spacer and a thin film transistor, and the spacer is interposed between the color filter substrate and the array substrate. The friction is easy to produce fragment of an alignment film, and further the bright defect occurs in the display panel. Because the bright defect is usually gathered at the edge of the display panel and present in a linear mode, the defect is usually named as a line zara, and the line zara seriously influences the image quality of final display products.
An embodiment of the present disclosure provides a display panel which includes: a color filter substrate and an array substrate which are cell-assembled together, a spacer disposed between the color filter substrate and the array substrate and including a plurality of primary spacers; an area located between the color filter substrate and the array substrate includes a display central area, a display middle area surrounding the display central area, and a display edge area surrounding the display middle area; a distribution density of the primary spacers in the display edge area is larger than a distribution density of the primary spacers in the display central area, and larger than a distribution density of the primary spacers in the display middle area.
An embodiment of the present disclosure provides a display device, and the display device includes the above-mentioned display panel.
In order to clearly illustrate the technical solution of the embodiments of the present disclosure, the drawings of the embodiments will be briefly described in the following; it is obvious that the described drawings are only related to some embodiments of the present disclosure and thus are not limitative of the present disclosure.
The technical solutions of the embodiment will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the disclosure. It is obvious that the described embodiments are just a part but not all of the embodiments of the disclosure. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the disclosure.
The embodiments of the present disclosure provide a display panel and a display device, and the Line Zara defect is less likely to occur in the display panel, the picture quality is improved.
As shown in
As shown in
The distribution density of the primary spacers 31 (for example the number of the spacers in per unit area) in the display edge area C is larger than the distribution density of the primary spacers 31 in the display central area A, and larger than the distribution density of the primary spacers 31 in the display middle area B.
In a display panel, the spacers disposed between the color filter substrate and the array substrate mainly play a role of supporting, meanwhile, the top end and the bottom end of a primary spacer are connected with the color filter substrate and the array substrate respectively, thus it can produce friction with the color filter substrate as well as the array substrate to prevent the relative displacement between the color filter substrate and the array substrate.
In a display panel of an embodiment of the present disclosure, the distribution density of the primary spacers 31 in the display edge area C is larger than the distribution density of the primary spacers 31 in the display central area A, and larger than the distribution density of the primary spacers 31 in the display middle area B as well, that is the number of the primary spacers 31 in the edge area C of the display panel is more. Therefore, the color filter substrate 1 and the array substrate 2 in the edge area C of the display panel burden a larger frictional force from the primary spacers 31. Therefore, in a display panel of the embodiment of the present disclosure, the relative displacement is less likely to occur in the edge portion(s) of the color filter substrate 1 and the array substrate 2. Therefore, the line zara defect is less likely to occur in the display panel of the embodiment, and the picture quality becomes good.
As shown in
In an embodiment of the present disclosure, for example, as shown in
As shown in
The above-mentioned setting modes of the distribution density of the primary spacers 31 in each area can make the distribution density of the primary spacers 31 from the central to the edge of the display panel increase, that is, make the distribution density variation of the primary spacers 31 more uniform, and further the relative displacement is less likely to occur between the color filter substrate 1 and the array substrate 2; therefore, the line zara defects arc less likely to occur throughout the whole display panel.
As shown in
On the basis of the above-mentioned embodiments, in an embodiment, the distribution density of the primary spacers 31 in the display central area A is 1/72 (i.e., every 72 sub-pixels correspond to one primary spacers); the distribution density of the primary spacers 31 in the display middle area B is 1/36 (i.e., every 36 sub-pixels correspond to one primary spacers); the distribution density of the primary spacers 31 in the display edge area C is 1/24 (i.e., every 24 sub-pixels correspond to one primary spacers).
As shown in
In the case that the distribution density of the primary spacers 31 in the display edge area C is larger than the distribution density of the primary spacers 31 in the display central area A and also larger than the distribution density of the primary spacers 31 in the display middle area B, the distribution density of the auxiliary spacers 32 in the display edge area C is smaller than the distribution density of the auxiliary spacers 32 in the display central area A and also smaller than the distribution density of the auxiliary spacers 32 in the display middle area B.
In the case that the distribution density of the primary spacers 31 in the display edge area C is larger than the distribution density of the primary spacers 31 in the display middle area B, and the distribution density of the primary spacers 31 in the display middle area B is larger than the distribution density of the primary spacers 31 in the display central area A, the distribution density of the auxiliary spacers 32 in the display edge area C is smaller than the distribution density of the auxiliary spacers 32 in the display middle area B, and the distribution density of the auxiliary spacers 32 in the display middle area B is smaller than the distribution density of the auxiliary spacers 32 in the display central area A.
In the case that the distribution density of the primary spacers 31 in the display central area A, the distribution density of the primary spacers 31 in the display middle area B, and the distribution density of the primary spacers 31 in the display edge area C are increased linearly in sequence, the distribution density of the auxiliary spacers 32 in the display central area A, the distribution density of the auxiliary spacers 32 in the display middle area B, and the distribution density of the auxiliary spacers 32 in the display edge area C are decreased linearly in sequence.
In the case that in the display central area A, along the direction from the center of this area to the edge of this area, the distribution density of the primary spacers 31 is increased linearly; in the display middle area B, along the direction from the inner edge of this area to the outer edge of this area, the distribution density of the primary spacers 31 is increased linearly; in the display edge area C, along the direction from the inner edge of this area to the outer edge of this area, the distribution density of the primary spacers 31 is increased linearly; in this case, in the display central area A, along the direction from the center of this area to the edge of this area, the distribution density of the auxiliary spacers 32 is decreased linearly; in the display middle area B, along the direction from the inner edge of this area to the outer edge of this area, the distribution density of the auxiliary spacers 32 is decreased linearly; in the display edge area C, along the direction from the inner edge of this area to the outer edge of this area, the distribution density of the auxiliary spacers 32 is decreased linearly.
Of course, the setting of the auxiliary spacers 32 in the embodiments of the present disclosure is not limited to the above-mentioned modes or methods, in the case that the positions used for setting the spacers is enough to meet the distribution density setting of the primary spacers, the distribution density of the auxiliary spacers in each area may also be the same.
