Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic top view of a display panel according to an embodiment of the present invention, and fig. 2 is a schematic cross-sectional view along an AA direction in fig. 1, which is shown in fig. 1 and 2, and the display panel includes a display area 10 and a non-display area 20 surrounding the display area. The display panel further includes an array substrate 30, a counter substrate 40 opposite to the array substrate 30, and a liquid crystal layer 50 between the array substrate 30 and the counter substrate 40. The counter substrate 40 includes a substrate 41 and a black matrix 42 located on a side of the substrate 41 adjacent to the liquid crystal layer 50; the counter substrate 40 has the color resist layer 43 in the non-display region 20 and has no color resist layer 43 in the display region 10; the color resist layer 43 is located on the side of the black matrix 42 in the non-display area 20 away from the base substrate 41.
The display panel is black and white, and the opposite substrate 40 of the display panel is not provided with the color resist layer 43 in the display region 10. Note that the black matrix 42 in the non-display region 20 of the counter substrate 40 continuously and uniformly covers the base substrate 41, and the black matrix in the display region 10 of the counter substrate 40 is provided with a plurality of open light-transmitting regions, each of which corresponds to an effective display region of one pixel.
As shown in fig. 1 and 2, the non-display region 20 of the array substrate 30 of the display panel is provided with a plurality of gate leads 31, one end of each gate lead 31 is connected to a corresponding gate line 32 in the display region 10 of the array substrate 30, and the other end of each gate lead 31 is connected to a driving circuit 33 of the display panel. The scan signal output from the driving circuit 33 is transmitted to the corresponding gate line 32 in the display region 10 of the array substrate 30 through the gate lead 31, thereby driving the pixel unit of the display region 10. The pixel units in the display area are arranged in a matrix mode. Each pixel unit comprises a thin film transistor which plays a role of a switch. The gate of the thin film transistor is connected to the gate lead through the gate line. The on and off of the thin film transistor can be controlled by controlling the voltage output by the driving circuit to the gate line, the source electrode of the thin film transistor is connected with the data line, the drain electrode of the thin film transistor is connected with the pixel electrode, the voltage on the pixel electrode is changed by controlling the voltage on the data line, so that the electric field distribution around the liquid crystal is changed, the deflection angle of the liquid crystal is changed accordingly, the intensity of light passing through the light-transmitting area is adjusted, and the brightness of the pixel is adjusted. It should be noted that the exemplary gate lead lines 31 disposed in the non-display area 20 on both sides of the display area 10 of the display panel in fig. 2 are, for example, the gate lead lines 31 connected to the odd-numbered gate lines 32 are disposed in the non-display area 20 on the left side of the display area 10 in fig. 2, and the gate lead lines 31 connected to the even-numbered gate lines 32 are disposed in the non-display area 20 on the right side of the display area 10 in fig. 2. In other embodiments, the gate lead 31 may be disposed only in the non-display area 20 on one side of the display area 10, that is, the gate lead 31 is led out on the same side of the gate line 32, which is not limited in this embodiment of the present invention. The driving circuit 33 may be located on one or both of the left and right sides of the display panel in fig. 1, or on the top side or the bottom side, which is not limited in the embodiment of the present invention.
In practical applications, it is found that when the display panel is started, the voltage on the gate lead changes from 0V to a positive value (e.g. 15V), and the change of the voltage causes an induced electromagnetic field to be generated around the gate lead 31, and under the action of the induced electromagnetic field, free charges (e-) are induced in the black matrix 42 in the non-display area 20 of the opposite substrate 40, and the free charges move towards the display area 10 of the array substrate 30 under the action of an electric field between the common electrode and the pixel electrode disposed in the display area 10 of the array substrate 30, so as to generate a built-in additional electric field, which affects the electric field built-in distribution in the adjacent display area. Due to the superposition of the original electric field between the common electrode and the pixel electrode and the additional electric field of the free charges, the liquid crystal is abnormal in rotation, so that the liquid crystal which is originally required to be driven to deflect and display a required black picture is generated, a white phenomenon is generated at the edge of a display area, and the display quality is influenced. In order to solve the problem, the color resistance layer 43 is arranged on the side, away from the substrate 41, of the black matrix 42 in the non-display area 20 of the opposite substrate 40, so that part of free charges generated by the black matrix 42 in the non-display area 20 can be prevented from moving to the display area 10 of the array substrate 30, the influence of the free charges on the electric field distribution of the display area is reduced, the white phenomenon generated by the part of the display area 10 close to the two sides of the frame when the liquid crystal display screen is started is reduced or eliminated, and the picture display quality is improved.
Alternatively, referring to fig. 2, the array substrate 30 has a common electrode 35 and a pixel electrode 36 in the display region 10; the common electrode 35 and/or the pixel electrode 36 are provided with a plurality of opening structures. An electric field parallel to the array substrate can be formed between the common electrode 35 and the pixel electrode 36, and the common electrode 35 provides the same potential for each pixel. Practical studies show that the display panel with the structure has a large visual angle, but the whitening phenomenon is more likely to occur in the display area of the display panel near the two sides of the frame. Therefore, it is necessary to provide the color resist layer 43 in the non-display area of the counter substrate of the display panel with the above structure to reduce or eliminate the white phenomenon generated in the display area near the two sides of the frame when the liquid crystal display is started, thereby improving the image display quality.
In addition, in the embodiment of the present invention, the positions of the upper layer and the lower layer of the pixel electrode 36 and the common electrode 35 are not limited, and for example, the pixel electrode 36 and the common electrode 35 may be arranged in a same layer or in a different layer in an insulating manner. In the exemplary arrangement of fig. 5, the pixel electrode 36 and the common electrode 35 are arranged in different layers and insulated, the pixel electrode 36 is located on one side of the common electrode 35 adjacent to the liquid crystal layer 50, a plurality of opening structures are arranged in the pixel electrode 36, and the common electrode 35 is a whole-surface electrode. In other embodiments, the upper and lower layer positions of the pixel electrode 36 and the common electrode 35 may be adjusted according to actual product requirements, for example, the pixel electrode 36 of each pixel unit may be a whole-surface electrode, and the common electrode 35 is provided with a plurality of opening structures.
The color resistance layer 43 may be made of a color resistance material commonly used in the existing color display panel, and if the color resistance material has a certain conductivity, part of the free charges induced on the black matrix will be injected into the color resistance layer 43, so as to dilute the surface concentration of the induced free charges, thereby reducing the influence of the induced free charges on the liquid crystal deflection of the display area.
Optionally, the color resistance layer 43 may also be an insulating material. When the color resist layer 43 is made of an insulating material, the color resist layer 43 can completely block the free charges generated by the black matrix 42 in the non-display area 20 from moving to the display area 10 of the array substrate 30, so as to prevent the built-in additional electric field generated by the free charges from affecting the deflection of the liquid crystal in the display area 10.
Optionally, the color resist layer 43 is a single color resist. Since the present invention is suitable for black-and-white display, it is not necessary to provide color resists of a plurality of colors in the display region, and the color resist 43 in the non-display region 10 of the counter substrate 40 can be a single color resist, which can reduce the exposure process and save the cost compared to a case of using color resists of a plurality of colors. The color of the color resist layer 43 is not limited in the embodiment of the present invention, for example, the color resist layer 43 is any one of a red color resist layer, a green color resist layer, or a blue color resist layer.
Optionally, the color-resist layer 43 is adjacent to the edge of the display area 10, and the edge of the color-resist layer 43 overlaps with the boundary of the display area 10 and the non-display area 20. Since the free charges generated from the black matrix 42 in the non-display area 20 near the edge of the display area 10 are relatively easy to move to the display area 10 because they are closer to the display area 10, the color resist layer 43 is disposed near the edge of the display area 10, and the free charges generated from the black matrix 42 in the non-display area 20 near the edge of the display area 10 can be effectively blocked from moving to the display area 10 of the array substrate 30. Setting the edge of the color-resist layer 43 to overlap the boundary of the display area 10 and the non-display area 20 may prevent the free charges induced on the black matrix 42 from moving to the display area 10 of the array substrate 30 through a gap between the edge of the color-resist layer 43 and the boundary of the display area 10 and the non-display area 20, compared to a case where the edge of the color-resist layer 43 has a certain distance from the boundary of the display area 10 and the non-display area 20. The edge of the color resist layer 43 away from the display region 10 is not limited in the embodiment of the present invention, for example, the edge of the color resist layer 43 away from the display region 10 may be overlapped with the edge of the frame sealing adhesive of the display panel adjacent to the display region.
Fig. 3 is a schematic top view of a display panel according to an embodiment of the present invention, and as shown in fig. 3, a non-display area 20 of the display panel according to the embodiment of the present invention includes a virtual pixel area 21, the virtual pixel area 21 surrounds a display area 10, and a color resistance layer 43 is located in the virtual pixel area 21. The arrangement of the dummy pixel region 21 can prevent the shrinkage of the alignment films on the counter substrate and the array substrate and the display area display failure caused by the uneven alignment of the alignment films during the alignment process. The black matrix of the dummy pixel region 21 of the opposite substrate may be continuously disposed to prevent the light leakage phenomenon from occurring, or may be intermittently disposed to reduce the generation of free charges. The dummy pixel area 21 may be provided with liquid crystal to avoid the problem of non-uniform orientation of the edge of the liquid crystal layer after rubbing orientation, and the liquid crystal with non-uniform orientation is left in the dummy pixel area 21 to ensure uniform liquid crystal alignment in the display area. Referring to fig. 3, in the non-display area 20 of the array substrate 30, at least one dummy pixel unit is disposed in the dummy pixel area 21 in a direction perpendicular to the edge of the display area 10. The dummy pixel unit generally has the same structure as the pixel unit normally displayed in the display area 10, and may include, for example, a thin film transistor, a pixel electrode, and a common electrode, but is not displayed in the display stage, for example, a scan signal or a data signal may not be provided to the thin film transistor corresponding to the dummy pixel unit, and at least one of a gate, a source, and a drain of the thin film transistor corresponding to the dummy pixel unit may be suspended, for example, the gate line may not be connected to the gate of the thin film transistor, the data line may not be connected to the source of the thin film transistor, and the pixel electrode may not be connected to the drain of the thin film transistor. Since the dummy pixel unit generally has the same structure as the pixel unit normally displayed in the display region 10, the film structures of the dummy pixel unit on the opposite substrate side and the array substrate side are substantially the same as or the same as the film structure of the adjacent display region, and the induced free charges are more likely to gather there and move toward the array substrate under the action of the electric field of the display region. The dummy pixel region 21 surrounds the display region 10 and is adjacent to the edge of the display region 10, and the color resist layer 43 is disposed in the dummy pixel region, so that the free charges generated from the black matrix 42 in the non-display region 20 adjacent to the edge of the display region 10 can be effectively blocked from moving to the display region 10 of the array substrate 30. It should be noted that, in the example of fig. 3, the color resist layer 43 is arranged to completely cover the virtual pixel region 21, and compared with the case that the color resist layer is further covered on the fan-out region and/or the frame sealant region at the periphery of the virtual pixel region, the original structure of the fan-out region and/or the frame sealant region may be prevented from being changed as much as possible, and it is not necessary to redesign the size or position of various element structures in the fan-out region and/or the frame sealant region, so as to avoid generating other design defects or obstacles, and meanwhile, the color resist layer 43 completely covers the virtual pixel region 21, which not only can effectively prevent the free charges from moving to the display region 10 of the array substrate 30, but also can prevent the display region from being badly displayed due to shrinkage of the alignment films on the opposite substrate and the array substrate and unevenness of the alignment films in the alignment process. In other embodiments, the color-resist layer 43 may cover part of the virtual pixel region 21, or may cover at least part of the non-display region 20 outside the virtual pixel region 21 on the basis of completely covering the virtual pixel region 21.
Alternatively, referring to fig. 3, the color-resist layer 43 may be continuously disposed along the edge of the display area 10, i.e., the color-resist layer 43 is continuously and uninterruptedly disposed around the display area. The color resist layer 43 is continuously disposed, and the black matrix 42 of the non-display area 20 is uniformly covered by the color resist layer 43, so that the movement of free charges can be better blocked compared with the discontinuous arrangement, and the flatness of the surface of the film layer where the color resist layer 43 is located is ensured, thereby facilitating the alignment of the alignment film on the opposite substrate.
Fig. 4 is a schematic top view of another display panel according to an embodiment of the present invention, and as shown in fig. 4, the array substrate 30 includes a plurality of data lines 34 and a plurality of gate lines 32 crossing each other in an insulating manner; the non-display area 20 includes a first non-display area 22 and a second non-display area 23 oppositely disposed in a direction parallel to the gate line 32; the black matrix 42 in the first non-display region 22 and the second non-display region 23 is located on the side of the color resist layer 43 away from the base substrate (not shown in fig. 4). Since the black matrix 42 above the gate lead 31 (i.e., the first non-display region 22 and the second non-display region 23) is severely affected by the electromagnetic field generated by the voltage variation of the gate lead 31, the generated free charges are more, and the denser the gate lead 31 is, the more the free charges generated by the black matrix 42 above the gate lead 31 are, the color resistance layer 43 is disposed on the side of the black matrix 42 in the first non-display region 22 and the second non-display region 23 away from the substrate 41, so that the free charges generated by the black matrix 42 in the first non-display region 22 and the second non-display region 23 can be effectively blocked from moving to the display region 10 of the array substrate 30. Alternatively, the gate wiring 31 is located in the first non-display region 22 or the second non-display region 23 on the array substrate, and the color resist layer 43 is disposed on the side of the black matrix 42 in the first non-display region 22 or the second non-display region 23 away from the substrate 41.
Fig. 5 is a schematic cross-sectional view of another display panel according to an embodiment of the present invention, and as shown in fig. 5, an opposite substrate 40 of the display panel according to the embodiment of the present invention further includes a planarization layer 44; the planarization layer 44 is located on the side of the black matrix 42 away from the substrate base plate 41, and the color resist layer 43 is located between the planarization layer 44 and the black matrix 42. The color resist layer 43 is disposed between the planarization layer 44 and the black matrix 42, so that the color resist layer 43 can be prevented from affecting the flatness of the surface of the opposite substrate adjacent to the liquid crystal layer 50, and the planarization layer 44 can flatten the opposite substrate 40 adjacent to the liquid crystal layer 50, thereby ensuring uniform alignment of the entire opposite substrate 40 during subsequent rubbing alignment.
