Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a liquid crystal display panel and an electronic device. Background Technology

[0002] With the development of optoelectronic technology, people have increasingly demanded narrower bezels for Liquid Crystal Display (LCD) panels. However, the narrower the bezel of an LCD panel, the smaller the width of its adhesive, and the weaker the bond between the adhesive and the upper and lower substrates. Furthermore, since the edges and corners of the upper and lower substrates of an LCD panel are not flush, misaligned protruding corners are inevitable. Uneven stress on the upper and lower substrates during transport can cause the adhesive to peel off, leading to moisture ingress, liquid crystal leakage, and other problems, ultimately causing abnormal display functionality of the LCD panel.

The liquid crystal display panel 10 of this embodiment has a display area 11 and a non-display area 12, with the non-display area 12 located around the periphery of the display area 11. The liquid crystal display panel 10 includes a first substrate 13, a second substrate 14, a frame adhesive 15, and a liquid crystal layer 16. The second substrate 14 is disposed opposite to and spaced apart from the first substrate 13. The frame adhesive 15 is located in the non-display area 12 and is sandwiched between the first substrate 13 and the second substrate 14 to form a receiving space with the first substrate 13 and the second substrate 14. The liquid crystal layer 16 is received in the receiving space and is disposed corresponding to the display area 11. The frame adhesive 15 includes a first main body portion 151, a second main body portion 152, and a corner portion 153. The first main body portion 151 extends along a first direction D1, and the second main body portion 152 extends along a second direction D2. The corner portion 153 connects the first main body portion 151 and the second main body portion 152. The corner portion 153 includes a first connecting portion 1531 and a second connecting portion 1532. The first connecting portion 1531 is located on the diagonal of the liquid crystal display panel 10 and is disposed on the side of the first main body portion 151 adjacent to the display area 11. One end of the second connecting portion 1532 is bent and connected to the second main body portion 152, and the other end is bent and connected to the first connecting portion 1531.

[0043] The liquid crystal display panel 10 may be, but is not limited to, a color filter (CF) substrate, a photoresist 17, an indium tin oxide (ITO) transparent electrode 18, and a thin film transistor (TFT) substrate.

In the schematic diagram of this embodiment, the second substrate 14 is illustrated as a TFT substrate, which is used to provide and transmit electrical signals to the liquid crystal display panel 10. The second substrate 14 can be disposed opposite to and spaced from the first substrate 13, thereby leaving a space between the first substrate 13 and the second substrate 14 for housing the liquid crystal layer 16.

[0047] The frame adhesive 15 can be formed by, but is not limited to, a coating process. It is understood that the frame adhesive 15 can also be formed by other processes, and the formation process of the frame adhesive 15 should not be construed as limiting the frame adhesive 15 provided in the embodiments of this application. The frame adhesive 15 can be located within the non-display area 12, and the frame adhesive 15 can be sandwiched between the first substrate 13 and the second substrate 14, thereby cooperating with the first substrate 13 and the second substrate 14 to form a receiving space for receiving the liquid crystal layer 16. The frame adhesive 15 can be bonded to the first substrate 13 and the second substrate 14, thereby preventing moisture from entering the liquid crystal layer 16, and can also be used to prevent the liquid crystal layer 16 from being corroded and to prevent leakage of the liquid crystal layer 16.

[0048] The liquid crystal layer 16 may be disposed within the receiving space formed by the CF substrate, the TFT substrate, and the frame adhesive 15. The liquid crystal layer 16 may be formed, but is not limited to, by a drop-casting process. It is understood that the liquid crystal layer 16 may also be formed by other processes, and the formation process of the liquid crystal layer 16 should not be construed as a limitation on the liquid crystal display panel 10 provided in this application. The liquid crystal layer 16 is disposed corresponding to the display area 11 of the liquid crystal display panel 10, thereby being used for displaying the image on the liquid crystal display panel 10.

[0049] The first main body portion 151 of the frame adhesive 15 may be, but is not limited to, a strip-shaped or substantially strip-shaped adhesive. The first main body portion 151 may extend along the first direction D1. The number of the first main body portions 151 may be, but is not limited to, two or more.

[0051] The corner portion 153 can be connected between the first main body portion 151 and the second main body portion 152, thereby cooperating with the first main body portion 151 and the second main body portion 152 to encapsulate the liquid crystal layer 16. The corner portion 153 can be located at the corner of the liquid crystal display panel 10. The number of corner portions 153 can be, but is not limited to, one, two, three or four. In the schematic diagram of the embodiment of this application, four corner portions 153 are used as an example to illustrate the encapsulation of the liquid crystal layer 16 of the liquid crystal display panel 10.

[0052] The first direction can be, but is not limited to, parallel to or substantially parallel to the short side direction or the long side direction of the liquid crystal display panel 10. In the schematic diagrams of this application embodiment, examples are given where the first direction D1 is parallel to the short side direction or the long side direction of the liquid crystal display panel 10. It can be understood that the first direction D1 can also be other directions, and the first direction D1 should not be construed as a limitation on the liquid crystal display panel 10 provided in this application embodiment.

[0053] The second direction D2 can be, but is not limited to, parallel to or substantially parallel to the long side direction or the short side direction of the liquid crystal display panel 10, and the extension direction of the second direction D2 is different from that of the first direction D1.

[0054] The first connecting portion 1531 can be, but is not limited to, a strip-shaped or roughly strip-shaped adhesive. The first connecting portion 1531 can be located on the side of the first main body 151 adjacent to the display area 11, thereby ensuring that the liquid crystal display panel 10 has a narrow bezel design while effectively extending the first connecting portion 1531, thus enhancing the adhesion between the first substrate 13 and the second substrate 14, reducing the peeling of the frame adhesive 15, and ensuring the normal operation of the liquid crystal display panel 10. The first connecting portion 1531 can be located on the diagonal of the liquid crystal display panel 10, thereby effectively resisting the external forces commonly experienced by the liquid crystal display panel 10 on the diagonal, effectively preventing the peeling of the frame adhesive 15, thus avoiding moisture entering the liquid crystal layer 16, corrosion of the liquid crystal layer 16, and leakage of the liquid crystal layer 16, thereby ensuring the normal display effect of the liquid crystal display panel 10.

[0055] The second connecting portion 1532 can be, but is not limited to, a strip-shaped or substantially strip-shaped adhesive. One end of the second connecting portion 1532 is bent and connected to the second main body portion 152, and the bending angle of the second connecting portion 1532 to the second main body portion 152 can be, but is not limited to, 100°, 110°, or 120°. The other end of the second connecting portion 1532 is bent and connected to the first connecting portion 1531, and the bending angle between the second connecting portion 1532 and the first connecting portion 1531 can be, but is not limited to, 90° or substantially 90°. It is understood that the bending angle between the second connecting portion 1532 and the first connecting portion 1531 can also be other angles, and the bending angle between the second connecting portion 1532 and the first connecting portion 1531 should not be construed as a limitation on the frame adhesive 15 provided in the embodiments of this application. In the schematic diagram of this embodiment, the bending angle between the second connecting portion 1532 and the first connecting portion 1531 is 90° as an example. This effectively prevents the frame adhesive 15 from peeling off while facilitating path calculation of the frame adhesive 15 during the manufacturing process. The second connecting portion 1532 can be located on the side of the second main body portion 152 adjacent to the display area 11. This ensures that the liquid crystal display panel 10 has a narrow bezel design, while the second connecting portion 1532 can be effectively extended, thereby enhancing the adhesion between the first substrate 13 and the second substrate 14, reducing the peeling of the frame adhesive 15, and ensuring the normal operation of the liquid crystal display panel 10.

[0056] In summary, the frame adhesive 15 has a first connecting portion 1531 and a second connecting portion 1532 at the corner portion 153. The first connecting portion 1531 is located on the diagonal of the liquid crystal display panel 10, and is disposed on the side of the first main body portion 151 adjacent to the display area 11. One end of the second connecting portion 1532 is bent and connected to the second main body portion 152, and the other end is bent and connected to the first connecting portion 1531. The second connecting portion 1532 is located on the side of the second main body portion 152 adjacent to the display area 11, thereby effectively resisting the external force that the liquid crystal display panel 10 is subjected to on the diagonal, thereby effectively preventing the frame adhesive 15 from peeling off, thus avoiding moisture entering the liquid crystal layer 16, corrosion of the liquid crystal layer 16, and leakage of the liquid crystal layer 16, thereby ensuring the normal display effect of the liquid crystal display panel 10.

Figure 4 The first connecting portion 1531 has a dimension L1 along the diagonal direction of the liquid crystal display panel 10, and a dimension L2 along the direction perpendicular to the diagonal direction of the liquid crystal display panel 10, wherein L1 > L2.

[0058] The diagonal direction can be the diagonal direction corresponding to the liquid crystal display panel 10. The dimension of the first connecting part 1531 along the diagonal direction can be L1, and the dimension of the first connecting part 1531 perpendicular to the diagonal direction can be L2. L1 > L2, that is, the dimension of the first connecting part 1531 along the diagonal direction is greater than the dimension of the first connecting part 1531 perpendicular to the diagonal direction, thereby effectively enhancing the adhesive force of the first connecting part 1531 in the diagonal direction, and thus effectively resisting the peeling of the frame adhesive 15 of the liquid crystal display panel 10 from the external force that is often subjected to in the diagonal direction, thereby ensuring the safe and normal operation of the liquid crystal display panel 10.

[0059] Please refer to it again. Figure 4 The other end of the second connecting portion 1532 is perpendicularly connected to the first connecting portion 1531.

[0060] The other end of the second connecting part 1532 is perpendicularly connected to the first connecting part 1531, thereby effectively preventing the frame adhesive 15 from peeling off while facilitating path calculation of the frame adhesive 15 during the process formation, thereby reducing the production cost of the liquid crystal display panel 10.

[0082] Please see Figure 7 , Figure 7 This is a partial structural schematic diagram of a liquid crystal display panel according to an embodiment of this application. The first substrate 13 has a first surface 133 facing the second substrate 14, and the second substrate 14 has a second surface facing the first substrate 13. At least one of the first surface 133 and the second surface has a recess 134 in the portion where a frame is formed, and the size between the two points with the largest distance between the two recesses 134 is 10 μm to 100 μm.

[0083] The first surface 133 can be the surface of the first substrate 13 facing the second substrate 14. The first surface 133 can be, but is not limited to, having a recess 134 in the portion where the frame is formed. The recess 134 is used to increase the specific surface area of ​​the first surface 133 of the first substrate 13, thereby increasing the contact area between the first substrate 13 and the frame adhesive 15, thereby strengthening the adhesion of the frame adhesive 15 to the first substrate 13, and effectively preventing the frame adhesive 15 from peeling off.

[0084] The second surface can be the surface of the second substrate 14 facing the first substrate 13. The second surface can be, but is not limited to, having a recess 134 in the portion where the adhesive frame is disposed. The recess 134 increases the specific surface area of ​​the second surface of the second substrate 14, thereby increasing the contact area between the second substrate 14 and the adhesive frame 15, thus strengthening the adhesion of the adhesive frame 15 to the second substrate 14 and effectively preventing peeling of the adhesive frame 15. At least one of the first surface 133 and the second surface has a recess 134 in the portion where the adhesive frame is disposed. In the schematic diagram of the embodiment of this application, an example is given where the portion of the first surface 133 where the adhesive frame 15 is disposed has a recess 134.

[0085] The recess 134 can be, but is not limited to, being achieved by laser roughening. Understandably, the recess 134 can also be achieved by other processes, such as etching. The process of achieving the recess 134 should not be construed as a limitation on the liquid crystal display panel 10 provided in the embodiments of this application.

[0086] The dimension between the two points with the largest spacing in the recess 134 can be, but is not limited to, 10μm, 30μm, 60μm, or 100μm. The recess 134 can effectively increase the specific surface area of ​​the portion of the first substrate 13 and the second substrate 14 where the frame adhesive 15 is provided, thereby increasing the adhesion between the frame adhesive 15 and the first substrate 13 and the second substrate 14, thus effectively preventing the frame adhesive 15 from peeling off when subjected to external force, thereby protecting the liquid crystal layer 16 from corrosion and leakage.

[0087] Please see Figure 8 , Figure 9 and Figure 10 , Figure 8 This is a partial structural schematic diagram of a liquid crystal display panel according to an embodiment of this application. Figure 9 This is a partial structural schematic diagram of a liquid crystal display panel 10 according to an embodiment of this application. Figure 10This is a partial structural schematic diagram of a liquid crystal display panel 10 according to an embodiment of this application. At least one of the first surface 133 and the second surface has a setting area 135, the setting area 135 having the recess 134, and the orthographic projection of the setting area 135 onto the first substrate 13 is a first projection 1351. The orthographic projection of the corner portion 153 onto the first substrate 13 is a second projection 1535, the second projection 1535 being smaller than the first projection 1351, and the second projection 1535 being completely within the range of the first projection 1351. The distance d3 between each boundary in the second projection 1535 and the corresponding boundary in the first projection 1351 is ≥ 2d4, where d4 is the linewidth of the larger of the linewidths of the first connecting portion 1531 and the second connecting portion 1532.

[0088] The setting area 135 may be, but is not limited to, being disposed on the first surface 133, or the second surface, or simultaneously on both the first surface 133 and the second surface. When the setting area 135 is disposed on both the first surface 133 and the second surface, it can effectively increase the adhesion between the frame adhesive 15 and the first substrate 13 and the second substrate 14. When the setting area 135 is disposed on one of the first surface 133 and the second surface, the manufacturing process cost of the liquid crystal display panel 10 can be appropriately reduced. In the schematic diagram of the embodiment of this application, the setting area 135 on the first surface 133 is used as an example for illustration. The distribution area of ​​the setting area 135 may be, but is not limited to, being distributed at the four corners of the first surface 133 or the second surface, thereby effectively preventing the frame adhesive 15 from peeling off at the corners.

[0089] The first projection 1351 can be the orthographic projection of the setting area 135 onto the first substrate 13. The second projection 1535 can be the orthographic projection of the corner portion 153 onto the first substrate 13. The second projection 1535 can be smaller than the first projection 1351, so that the corner portions 153 are all located on the setting area 135, thereby increasing the contact area between the corner portions 153 and the first substrate 13, and thus increasing the adhesion between the frame adhesive 15 and the corner portion 153 and the first substrate 13, thereby effectively preventing the frame adhesive 15 from peeling off from the corner portion 153, and thus ensuring the normal display of the liquid crystal display panel 10.

[0090] The distance between each boundary in the second projection 1535 and the corresponding boundary in the first projection 1351 can be d3≥2d4, where d4 is the line width of the larger of the line widths of the first connecting portion 1531 and the second connecting portion 1532. This ensures that the corner portions 153 are all located on the setting area 135, thereby effectively increasing the adhesion between the frame adhesive 15 and the corner portion 153 and the first substrate 13, thus effectively preventing the frame adhesive 15 from peeling off from the corner portion 153, and thus ensuring the normal display of the liquid crystal display panel 10.

[0091] Please refer to it again. Figure 8 , Figure 9 and Figure 10 At least one of the first surface 133 and the second surface has a setting area 135, the setting area 135 having the recess 134. The width of the setting area 135 is greater than the width of the frame adhesive 15, and the greater width ranges from 100μm to 300μm.

[0092] The width of the setting area 135 can be greater than the width of the frame adhesive 15, and the range of the setting area 135 being greater than the width of the frame adhesive 15 can be, but is not limited to, 100μm, 200μm, or 300μm, thereby ensuring that the corner portion 153 of the frame adhesive 15 is distributed within the setting area 135, effectively increasing the adhesion between the frame adhesive 15 at the corner portion 153 and the first substrate 13, thereby effectively preventing the frame adhesive 15 from peeling off at the corner portion 153, thus ensuring the normal display of the liquid crystal display panel 10, while also maintaining the narrow bezel design of the liquid crystal display panel 10.

This application also provides an electronic device 1, which includes a backlight module 20 and a liquid crystal display panel 10, wherein the backlight module 20 provides a surface light source for the liquid crystal display panel 10.

[0094] The electronic device 1 can be, but is not limited to, a mobile phone display, a computer display, and a television display. The backlight module 20 provides a surface light source for the liquid crystal display panel 10. The corner portion 153 of the frame adhesive 15 of the liquid crystal display panel 10 includes a first connecting portion 1531 and a second connecting portion 1532. The first connecting portion 1531 is located on the diagonal of the liquid crystal display panel 10 and is disposed on the side of the first main body portion 151 adjacent to the display area 11. One end of the second connecting portion 1532 is bent and connected to the second main body portion 152, and the other end is bent and connected to the first connecting portion 1531. The second connecting portion 1532 is located on the side of the second main body portion 152 adjacent to the display area 11. The circuit design of the first connecting portion 1531 and the second connecting portion 1532 can strengthen the adhesion between the frame adhesive 15 and the first substrate 13 and the second substrate 14, effectively avoiding the risk of the corners of the first substrate 13 and the second substrate 14 being peeled off due to the frame adhesive 15 being peeled off. This effectively prevents problems such as moisture ingress, liquid crystal corrosion, and liquid crystal leakage. Therefore, it ensures the normal display function of the liquid crystal display panel 10 and the normal operation of the electronic device 1.
