Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

The inventor of the present invention has found that, in a use process of the liquid crystal display screen, a color film (CF for short) substrate in a central region of the liquid crystal display screen is greatly dislocated (about 30 micrometers) from an array substrate (also referred to as a TFT substrate), so that a position of a main spacer changes, and the color film moves down from a top end of a pillow at an original position, so that a liquid crystal cell thickness (cell gap) in the central region is low, and a phenomenon that a display color is bluish occurs, specifically, refer to fig. 1 to 3. In fig. 1, after the color film substrate 11 and the array substrate 12 are aligned in a normal state, the main spacer 13 is located on the pillow 14, the thickness of the display panel (i.e., the thickness of the liquid crystal cell) is H1, and the display color of the display panel is normal. Fig. 2 is a top view of the main spacer 13 and the pillow 14, and as can be seen from fig. 2, on the same side, the distance between the edge of the main spacer 13 and the edge of the pillow 14 is relatively small, and once the color filter substrate and the array substrate are greatly misaligned, as shown in fig. 3, the main spacer 13 is moved away from the top end of the pillow 14, in this case, in the area where the color filter substrate and the array substrate are misaligned, the thickness of the display panel is H2, and H2 is smaller than H1, that is, the thickness of the display panel is reduced, so that the color temperature of the display color in the central area of the display panel is increased, and the display color is turned blue.

In view of the foregoing technical problems, embodiments of the present invention provide a display panel and a display device, which can avoid a phenomenon that a color displayed locally on the display panel is bluish due to a decrease in a distance between a color film substrate and an array substrate after the color film substrate and the array substrate are misaligned.

The embodiment of the invention provides a display panel. As shown in fig. 4 to 6, the display panel includes a color film substrate 11, an array substrate 12, a first spacer 15 and a spacer pillow 16.

In this embodiment, since the distance between the first end and the second end of the spacer pillow is a first distance, the first end of the spacer pillow is far away from the thin film transistor, the second end of the spacer pillow is close to the thin film transistor, the distance between the central axis of the spacer pillow and the first edge of the top surface of the first spacer is a second distance, the central axis of the spacer pillow is perpendicular to the array substrate, the top surface of the first spacer is in contact with the spacer pillow, the first edge of the top surface of the first spacer is close to the thin film transistor, and the ratio of the second distance to the first distance is 3.5-6, even after the color film substrate moves relative to the array substrate in the direction away from the thin film transistor, the spacer can be kept in contact with the spacer pillow, and further, the phenomenon that the color of local display of the display panel is turned blue due to the fact that the distance between the color film substrate and the array substrate is reduced when the color film substrate and the array substrate are staggered is avoided.

The material of the semiconductor layer 162 may be the same as that of the active layer 1222, and the semiconductor layer 162 and the active layer 1222 may be prepared through the same process. The material of the second metal layer 163 may be the same as that of the source electrode 1223, and the second metal layer 163 and the source electrode 1223 may be prepared through the same process.

In yet another embodiment, the width of the first metal layer 161 is 68.5 microns. In yet another embodiment, the width of the first metal layer 161 is 69 microns. That is, the width of the first metal layer 161 ranges from 49 micrometers to 88.5 micrometers.

As shown in fig. 5 to 6, a distance between the first end D1 and the second end D2 of the spacer pillow 16 is a first distance S1, wherein the first end D1 is far away from the thin film transistor 121, the second end D2 is close to the thin film transistor 121, a distance between the central axis L of the spacer pillow 16 and the first side B1 of the TOP surface TOP1 of the first spacer 15 is a second distance S2, the central axis L is perpendicular to the array substrate 12, and a ratio of the second distance S2 to the first distance S1 is 3.5 to 6, i.e., S2/S1 is 3.5 to 6. In the present embodiment, the ratio of the second distance S2 to the first distance S1 is 4.5.

In another embodiment, the ratio of the second distance S2 to the first distance S1 is 3.5. In yet another embodiment, the ratio of the second distance S2 to the first distance S1 is 6.

In the present embodiment, as shown in fig. 6, the distance between the central axis L and the second side B2 of the TOP surface TOP1 of the first spacer 15 is a third distance S3. In the present embodiment, the central axis L of the spacer pillow 16 is located on the side of the TOP surface TOP1 of the first spacer 15 away from the tft 121, and the third distance S3 is smaller than the second distance S2. Thus, the size of the first spacer 15 can be reduced, and space can be saved.

In another embodiment, the central axis L of the spacer pillow 16 may pass through the center of the TOP surface TOP1 of the first spacer 15, and the third distance S3 is equal to the second distance S2.

In this embodiment, the spacer pillow 16 is cylindrical, and a diameter of one end of the spacer pillow 16 close to the color filter substrate 11 is equal to the first distance S1. Alternatively stated, the TOP surface TOP2 of the spacer pillow 16 is circular with a diameter equal to the first distance S1. The spacer pillow 16 has a diameter of 4 microns. In another embodiment, the spacer pillows 16 are 3 microns in diameter. In yet another embodiment, the spacer pillows 16 are 9 microns in diameter. In general, the first distance is 3 microns to 9 microns.

In this embodiment, as shown in fig. 4, the second spacer 17 is located between the color filter substrate 11 and the array substrate 12 and fixed on the color filter substrate 11, and a projection of the second spacer 17 on the color filter substrate 11 is located in a projection of the black matrix 115 on the color filter substrate 11.

As shown in fig. 4, the length of the second spacer 17 extending along the central axis L is less than the length of the first spacer 15 extending along the central axis L, and the distance between the second spacer 17 and the array substrate 11 is greater than zero. Or, the second spacer 17 does not contact the array substrate 11. When the projection of the second spacer 17 on the array substrate at least partially coincides with the projection of the thin film transistor 121 on the array substrate, the second spacer 17 does not contact the thin film transistor 121.

In this embodiment, the display panel further includes a liquid crystal layer (not shown), and the liquid crystal layer is located between the color film substrate 11 and the array substrate 12.

The display panel provided by the embodiment of the invention is particularly suitable for a liquid crystal display panel with super-large size and high resolution. The reason is as follows: first, the width of the first metal layer 161 is limited. Second, the smallest dimension of the side length of TOP1 of first spacer 15 (10 microns) is larger than the largest dimension of TOP2 of spacer pillow 16 (9 microns). If the first spacer 15 is designed to be in direct contact with the first metal layer 161, when the color filter substrate 11 and the array substrate 12 are greatly displaced, the first spacer 15 can easily move out of the first metal layer 161, resulting in occurrence of blue mura defect. While the first spacer 15 is designed to contact the spacer pillow 16, it is ensured that it is always in contact with the spacer pillow 16 by increasing the size of the TOP surface TOP1 of the first spacer 15, avoiding the occurrence of blue mura failure.

The embodiment of the invention also provides a display panel. Unlike the embodiment shown in fig. 6, in the present embodiment, as shown in fig. 7, the TOP surface TOP1 of the first spacer 15 has a rectangular shape. The TOP surface TOP1 of the first spacer 15 includes a first side B1, a second side B2, a third side B3 and a fourth side B4. The second side B2 and the first side B1 are the wide sides of the rectangle, and the third side B3 and the fourth side B4 are the long sides of the rectangle. The long side of the rectangle extends along the first end D1 in a direction pointing to the second end D2.

The embodiment of the invention also provides a display device which comprises a display module and the display panel of any one of the embodiments.

In this embodiment, since the distance between the first end and the second end of the spacer pillow is a first distance, the first end of the spacer pillow is far away from the thin film transistor, the second end of the spacer pillow is close to the thin film transistor, the distance between the central axis of the spacer pillow and the first edge of the top surface of the first spacer is a second distance, the central axis of the spacer pillow is perpendicular to the array substrate, the top surface of the first spacer is in contact with the spacer pillow, the first edge of the top surface of the first spacer is close to the thin film transistor, and the ratio of the second distance to the first distance is 3.5-6, even after the color film substrate moves relative to the array substrate in the direction away from the thin film transistor, the spacer can be kept in contact with the spacer pillow, and further, the phenomenon that the color of local display of the display device is turned to blue due to the fact that the distance between the color film substrate and the array substrate is reduced when the color film substrate and the array substrate are staggered is avoided.

The display device in this embodiment may be: any product or component with a display function, such as electronic paper, a mobile phone, a tablet computer, a television, a notebook computer, a digital photo frame, a navigator and the like.
