The thickness of the liquid crystal layer (i.e. the cell gap) is mainly controlled by the spacers formed between the color film substrate and the array substrate, that is, the spacers are used to maintain the cell gap between the color film substrate and the array substrate.

DETAILED DESCRIPTION

[0051] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0052] First, in order to facilitate the description of the relative position relationship and set point of each mechanism in the present application, the implementation scenario of the embodiments of the present application is described here.

[0053] The main structure of the liquid crystal display is the liquid crystal display panel. In the manufacturing process of the liquid crystal display panel, the design and control of the cell thickness is one of the key technologies of the liquid crystal display, which directly affects the quality of the liquid crystal display.

[0054] For a large-size liquid crystal display panel, due to the large area of the panel, deformation is easy to occur during pressing or carrying, which can easily cause the spacer to deviate from the original position, and further cause the liquid crystal panel to have light leakage and other defects.

[0055] In order to realize the display function, the related art sets the alignment film on both sides of the liquid crystal layer to make the liquid crystal molecules in the liquid crystal layer have orientation, but under the vibration factors such as carrying, the alignment film is also easy to fall off to the liquid crystal layer and generate internal bright spots in the display panel, which affects the product quality.

[0056] Reference is made below to Figures 1-6The application discloses a liquid crystal display panel and a liquid crystal display.

[0057] As shown in Figure 1 and Figure 2 The liquid crystal display panel comprises an array substrate 100, a color filter substrate 200, a liquid crystal layer 300, an alignment film 400 and a spacer 500.

[0058] The array substrate 100 is arranged opposite to the color filter substrate 200.

[0059] The liquid crystal layer 300 is arranged between the array substrate 100 and the color filter substrate 200.

[0060] The alignment film 400 is formed on the opposite surfaces of the array substrate 100 and / or the color filter substrate 200.

[0061] The spacer 500 is arranged between the array substrate 100 and the color filter substrate 200, and the spacer 500 comprises first spacers 510 and second spacers 520 arranged alternately, the second spacers 520 are arranged on the opposite sides of the first spacers 510, and gaps a are formed between the first spacers 510.

[0062] The volume of the gap a is not less than the volume of the alignment liquid flowing into the gap a when the alignment film 400 is prepared.

[0063] In the above embodiment, the gap a is formed between the first spacers 510 and the second spacers 520, so that the alignment liquid (PI liquid) is gathered in the gap a under the capillary action, and the contact area of the alignment film 400 is increased after the alignment liquid (PI liquid) is solidified to form the alignment film 400, that is, the alignment film 400 is formed not only on the surfaces of the array substrate 100 and / or the color filter substrate 200, but also in the gap a, so that the problem that the alignment film 400 is partially dropped into the liquid crystal layer 300 to cause internal bright spots in the display panel under the vibration factors such as carrying is greatly relieved, and the product quality is improved.

[0064] In addition, the second spacers 520 are arranged alternately with the first spacers 510, and the second spacers 520 are arranged on the opposite sides of the first spacers 510, so that the second spacers 520 and the first spacers 510 are prevented from deviating from the original positions and changing under the pressing of the liquid crystal display panel, and the light leakage and other bad phenomena of the liquid crystal panel are prevented.

[0065] In summary, the liquid crystal display panel provided according to the embodiments of this application, on the one hand, by forming a gap a between the first spacer 510 and the second spacer 520, the alignment film 400 is formed not only on the surface of the array substrate 100 and / or the color filter substrate 200, but also within the gap a. This can greatly alleviate the problem of partial shedding of the alignment film 400 onto the liquid crystal layer 300 and generating internal bright spots in the liquid crystal display panel under vibration factors such as handling. On the other hand, the second spacer 520 and the first spacer 510 are staggered, and the second spacer 520 is located on the opposite side of the first spacer 510. This can prevent the second spacer 520 and the first spacer 510 from shifting their original positions when the liquid crystal display panel is pressed, thereby ensuring that the liquid crystal panel does not suffer from defects such as light leakage.

[0066] In practice, this application can use an ARPPlate to coat the array substrate 100 or color filter substrate 200 and spacer 500 with alignment liquid (PI liquid), and then form the required alignment film 400 on the array substrate 100 or color filter substrate 200 and spacer 500 through alignment processes (such as friction alignment process / photoalignment) and other processes.

[0067] In some embodiments, one side of the middle portion of the second spacer 520 abuts against one side of the middle portion of the first spacer 510, one side of the upper portion of the second spacer 520 forms a gap a with the upper portion of one side of the first spacer 510, and one side of the lower portion of the second spacer 520 forms a gap a with the lower portion of the first spacer 510.

[0068] In this embodiment, gap a may be formed only on one side of the upper part of the second spacer 520 and the upper part of one side of the first spacer 510, and on one side of the lower part of the second spacer 520 and the lower part of the first spacer 510, while one side of the middle part of the second spacer 520 abuts against one side of the middle part of the first spacer 510.

[0069] This design prevents the first spacer 510 and the second spacer 520 from squeezing the alignment film 400 within the gap a when the liquid crystal display panel is pressed, thereby ensuring that the second spacer 520 and the first spacer 510 do not shift from their original positions.

[0070] In actual implementation, the number of gaps a for each spacer 500 is not less than two.

[0071] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the first spacer 510 includes a first surface 511 and a second surface 512 disposed opposite to the first surface 511.

[0072] The first surface 511 is fixedly connected with the array substrate 100, and the second surface 512 is abutted with the color film substrate 200; or the first surface 511 is fixedly connected with the color film substrate 200, and the second surface 512 is abutted with the array substrate 100.

[0073] For example, when the first surface 511 is fixedly connected with the array substrate 100, the second surface 512 is a circular arc surface, and the curvature center of the circular arc surface is located on the side of the circular arc surface away from the color film substrate 200.

[0074] If the color film substrate 200 and the array substrate 100 have a tendency of relative movement under external force, the liquid crystal display panel may be deformed, and in the related art, the second surface 512 is a plane, and the edge of the plane may be in contact with or even collide with the alignment film 400 on the color film substrate 200, thereby causing the alignment film 400 to be damaged.

[0075] In the embodiment of the present application, the second surface 512 is a circular arc surface, which can reduce the possibility of contact with the alignment film 400 on the color film substrate 200, thereby reducing the damage to the alignment film 400 or the damage to the edge of the second surface 512, and improving the display effect.

[0076] For example, when the second surface 512 is fixedly connected with the color film substrate 200, the first surface 511 is a circular arc surface, and the curvature center of the circular arc surface is located on the side of the circular arc surface away from the array substrate 100.

[0077] Similarly, in the embodiment of the present application, the first surface 511 is a circular arc surface, which can reduce the possibility of contact with the alignment film 400 on the array substrate 100, thereby reducing the damage to the alignment film 400 or the damage to the edge of the first surface 511, and improving the display effect.

[0078] As shown in FIGS. Figure 2 , Figure 3 and Figure 4 In some embodiments, the second spacer 520 includes a third surface 521 and a fourth surface 522 opposite to the third surface 521.

[0079] The third surface 521 is fixedly connected with the array substrate 100, and the fourth surface 522 is abutted with the color film substrate 200; or the third surface 521 is fixedly connected with the color film substrate 200, and the fourth surface 522 is abutted with the array substrate 100.

[0080] For example, when the third surface 521 is fixedly connected with the array substrate 100, the fourth surface 522 is a circular arc surface, and the curvature center of the circular arc surface is located on the side of the circular arc surface away from the color film substrate 200.

[0081] If the color film substrate 200 and the array substrate 100 have a tendency of relative movement under external force, the liquid crystal display panel may be deformed, in the related art, the fourth surface 522 is a plane, and an edge of the plane may contact or even collide with the alignment film 400 on the color film substrate 200, thereby causing the alignment film 400 to be damaged.

[0082] In the embodiment of the present application, the fourth surface 522 is a circular arc surface, which can reduce the possibility of contacting the alignment film 400 on the color film substrate 200, thereby reducing the problems of the alignment film 400 being damaged or the edge of the fourth surface 522 being damaged, and improving the display effect.

[0083] For example, when the fourth surface 522 is fixedly connected with the color film substrate 200, the third surface 521 is a circular arc surface, and the center of curvature of the circular arc surface is located on the side of the circular arc surface away from the array substrate 100.

[0084] Similarly, in the embodiment of the present application, the third surface 521 is a circular arc surface, which can reduce the possibility of contacting the alignment film 400 on the array substrate 100, thereby reducing the problems of the alignment film 400 being damaged or the edge of the third surface 521 being damaged, and improving the display effect.

[0085] As shown in FIGS. Figure 5 and Figure 6 In some embodiments, the liquid crystal display panel further includes a display area 610 and a virtual area 620 surrounding the display area 610.

[0086] The liquid crystal layer 300, the alignment film 400, and the spacers 500 are located in the display area 610.

[0087] The virtual area 620 is provided with a magnetostrictive column 700 and a magnetic field generating structure 800, the magnetostrictive column 700 is arranged on the array substrate 100, and the material of the magnetostrictive column 700 is a magnetostrictive material, such as Terfenol-D.

[0088] The magnetic field generating structure 800 is used to form a controllable magnetic field along the axis of the magnetostrictive column 700, so that the magnetostrictive column 700 extends to abut against the color film substrate 200.

[0089] It should be noted that in the prior art, after the liquid crystal display panel is sealed, when the vacuum is broken, the liquid crystal display panel will be deformed under the action of atmospheric pressure.

[0090] Through analysis of the in-plane structure of the edge of the display area 610, it is found that the height and proportion of the support (such as PS) of the virtual area 620 are small, and the deformation trend of the liquid crystal display panel is consistent with the height trend of the support, that is, the smaller the height of the support, the greater the deformation trend.

[0091] Due to process limitations, it is difficult to increase the height and proportion of the support for the virtual area 620, and every reduction in the step difference between the virtual area 620 and the display area 610 places higher demands on the process.

[0092] In the above embodiments of this application, a magnetostrictive column 700 and a magnetic field generating structure 800 are provided in the virtual area 620. When the vacuum is not broken after the liquid crystal display panel is assembled, the end of the magnetostrictive column 700 away from the array substrate 100 does not touch the color filter substrate 200. When the vacuum is broken after the liquid crystal display panel is assembled, the magnetostrictive column 700 extends to touch the color filter substrate 200 under the action of the magnetic field, so as to prevent the color filter substrate 200 of the virtual area 620 from being recessed towards the array substrate 100 and causing large deformation of the liquid crystal display panel.

[0093] like Figure 5 and Figure 6 As shown, in some embodiments, the magnetic field generating structure 800 includes: a coil 810, a shielding sleeve 820, and a control module.

[0094] The coil 810 is arranged around the magnetostrictive column 700.

[0095] The shielding sleeve 820 is fitted over the coil 810, and an insulating layer is provided between the shielding sleeve 820 and the coil 810.

[0096] The control module is electrically connected to the coil 810 and is used to control the magnitude of the current in the coil 810.

[0097] In this embodiment, when energized, the coil 810 generates a magnetic field. The direction of the magnetic field is along the axial direction of the magnetostrictive column 700, and the strength of the magnetic field is controlled by the magnitude of the current in the coil 810.

[0098] Based on the magnetostrictive effect, the length of the magnetostrictive column 700 changes under the action of a magnetic field along its axial direction, extending to contact the color filter substrate 200.

[0099] This application also provides a liquid crystal display, including the liquid crystal display panel described in any of the above embodiments.

[0100] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
