[0027] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application.

In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0028] First embodiment

[0029] like Figure 1 and Figure 2 As shown, the first embodiment of the present application provides a color filter substrate 1, including a base substrate 10, a common electrode layer 11 formed on the base substrate 10, a shading layer 12, a color resist layer 13, a planarization layer 14 and a plurality of support pillars 15, the shading layer 12 includes a plurality of shading units 121, the color resist layer 13 includes a plurality of color resist units 131 distributed in an array, the shading units 121 are located between adjacent color resist units 131, the planarization layer 14 covers the color resist layer 13, and the plurality of support pillars 15 are located on a side of the planarization layer 14 away from the base substrate 10, wherein the color filter substrate 1 also includes a non-Newtonian fluid layer 16, the non-Newtonian fluid layer 16 is located in any film layer between the common electrode layer 11 and the plurality of support pillars 15, and the non-Newtonian fluid layer 16 includes an internally hollow retaining wall 16a and a non-Newtonian fluid 16b contained in the retaining wall.

[0030] The color filter substrate 1 is applied to the liquid crystal display panel, and is arranged opposite to the array substrate 2, and a liquid crystal layer is filled between the two. A plurality of support columns 15 include a main support column and a secondary support column, wherein the height of the main support column is greater than the height of the secondary support column and is equal to the thickness of the liquid crystal layer, and the cross-sectional area of ​​the main support column is greater than the cross-sectional area of ​​the secondary support column. When the liquid crystal display panel is subjected to a high and low temperature vibration environment test, the array substrate 2 and the color filter substrate 1 are relatively displaced due to the impact of the base substrate 10, and the main support column is compressed or even damaged in contact with the electronic device of the array substrate 2, resulting in a partial yellowing phenomenon (Mura) under the white state screen after the test; in addition, when the liquid crystal display panel is subjected to a large external force impact, the deformation of the base substrate may also damage the support column 15, resulting in uneven screen display.

[0031] To this end, in the first embodiment of the present application, a non-Newtonian fluid layer 16 is provided in any membrane layer between the common electrode layer 11 and the plurality of support pillars 15. The non-Newtonian fluid 16b in the non-Newtonian fluid layer 16 has two states: a soft state and a relatively rigid state. Under normal conditions, when not impacted, the non-Newtonian fluid layer 16 maintains a soft state, the interaction force between molecules is relatively small, and the non-Newtonian fluid has flexibility. When impacted, the non-Newtonian fluid layer 16 exhibits strong shear thickening behavior and has a relatively rigid state.

[0032] Since the non-Newtonian fluid 16b is fluid, a retaining wall 16a needs to be provided to surround it to ensure that the non-Newtonian fluid 16b does not flow out and pollute other film layers. Optionally, the retaining wall 16a is made of polyimide PI. Figure 2 As shown, in the process, the retaining wall 16a is first coated on the common electrode layer 11 so that the thickness around it is higher than the thickness in the middle, and then the non-Newtonian fluid 16b is sprayed into the retaining wall 16a, and finally a layer of polyimide PI is coated to encapsulate the non-Newtonian fluid 16b in the retaining wall 16a.

[0033] When the liquid crystal display panel is subjected to high and low temperature vibration environment testing, due to external impact, the intermolecular force of the non-Newtonian fluid 16b is enhanced, and it has the characteristics of shear thickening, and the surface becomes hard, which can effectively block external impact force, increase the deformation resistance of the base substrate 10, prevent the base substrate 10 from deforming and causing the support column 15 to be over-compressed, reduce the friction between the support column 15 and the electronic devices on one side of the array substrate 2, prevent damage to the support column 15, and improve the uneven display phenomenon.

[0034] According to the color film substrate 1 provided in the embodiment of the present application, by adding a non-Newtonian fluid layer 16 in any film layer between the common electrode layer 11 and the multiple support pillars 15, and the non-Newtonian fluid layer 16 includes an internal hollow retaining wall 16a and a non-Newtonian fluid 16b contained in the retaining wall, it can not only reduce the damage of the support pillars 15 due to excessive compression and cause uneven display of the picture, but also increase the rigidity of the liquid crystal display panel, provide partial supporting force when it is impacted by external force, and reduce the problem of uneven display of the picture caused by deformation of the base substrate 10.

[0035] In some embodiments, Figure 1 As shown, the non-Newtonian fluid layer 16 is located between the common electrode layer 11 and the color resist layer 13 and the light shielding layer 12. The common electrode layer 11 is substantially planar, and the non-Newtonian fluid layer 16 is located between the color resist layer 13 and the light shielding layer 12. Since the non-Newtonian fluid layer 16 is disposed close to one side of the base substrate 10, the deformation resistance of the base substrate 10 can be increased, and the external impact force can be effectively blocked, and the base substrate 10 can be prevented from being deformed to cause the support column 15 to be overly compressed, and the friction between the support column 15 and the electronic device on one side of the array substrate 2 can be reduced, so as to prevent the support column 15 from being damaged, and improve the phenomenon of uneven display of the picture.

[0036] Furthermore, the color resist layer 13 includes a red color resist unit, a green color resist unit and a blue color resist unit. Figure 1 As shown, the color resist units 13 of different colors are shown with different shadow patterns. The color resist units 13 of different colors are generally prepared by dispersing a certain color of pigment in a photoresist solvent to form a certain color of photoresist, and then coating the color of the photoresist on a prepared substrate, and then sequentially undergoing exposure and development processes to prepare the required pattern. A shading unit 121 is provided in the non-overlapping area between adjacent color resist units 13 of different colors. The material of the shading layer 12 is a black matrix (BlackMatrix, referred to as BM), which is used to improve the contrast of the liquid crystal display panel.

[0037] Furthermore, the non-Newtonian fluid layer 16 includes any film layer that is entirely laid between the common electrode layer 11 and the plurality of support pillars 15. Since the non-Newtonian fluid layer 16 is entirely laid between the common electrode layer 11 and the color resist layer 13 and the light shielding layer 12, the metal traces of the common electrode layer 11 can be covered, thereby improving the overall flatness of the color filter substrate 1.

[0038] Furthermore, the non-Newtonian fluid 16b includes a polymer material and reinforced particles dispersed in the polymer material, and the volume ratio of the polymer to the reinforced particles is 2:3. In this embodiment, when the volume ratio of the polymer to the reinforced particles is 2:3, it can ensure that it has strong rigidity when subjected to external impact force, and increase the ability of the substrate 10 to resist deformation. Of course, the volume ratio of the polymer to the reinforced particles can also be other ratios, depending on specific usage requirements.

[0039] Further, the high molecular polymer includes, for example, but not limited to, polyethylene glycol and isopropyl alcohol; the reinforcing particles include, for example, but not limited to, silicon or calcium carbonate, wherein the diameter of the silicon particles or calcium carbonate (CaCO3) particles is in the micrometer level.

[0040] Furthermore, the color film substrate 1 also includes an alignment layer (not shown in the figure) located on the side of the plurality of support columns 15 away from the base substrate 10, and an alignment layer is also provided on one side of the array substrate 2, and the liquid crystal layer 3 is filled between the alignment layers on both sides. The alignment film is generally formed by adding a solvent to a resin material such as polyimide to reduce its viscosity, and has the characteristics of fluidity, high heat resistance, resistance to chemical solvents and radiation, and good electrical insulation properties. The production methods of the alignment film include printed plate transfer (APR) and inkjet printing. Taking the inkjet printing method as an example, the pattern of the alignment film is first input into the computer, and then the alignment film solution is sprayed onto the display substrate through a nozzle, and then heated and cured, and aligned to form a film surface with a channel microstructure.

[0041] Second embodiment

[0042] like Figure 3 As shown, the second embodiment of the present application provides a color filter substrate 1, which has a similar structure to the color filter substrate 1 shown in the first embodiment, except that the non-Newtonian fluid layer 16 is not laid in an entire layer between the common electrode layer 11 and the color resist layer 13 and the light shielding layer 12.

[0043] Specifically, since the entire non-Newtonian fluid layer 16 will lose some light transmittance, in this embodiment, the non-Newtonian fluid layer 16 only covers the area corresponding to the shading unit 121, and the area corresponding to the color resist unit 131 is left blank to reduce the loss of light transmittance.

[0044] like Figure 3 and Figure 4 As shown, the non-Newtonian fluid layer 16 includes a plurality of fluid units 161, which are arranged in parallel or crosswise, and the orthographic projection of the fluid unit 161 on the base substrate 10 falls into the orthographic projection of the light shielding unit 121 on the base substrate 10. Each fluid unit 161 includes a hollow retaining wall unit 161a and a non-Newtonian fluid 16b contained in the retaining wall unit 161a.

[0045] Since the non-Newtonian fluid 16b is fluid, a retaining wall unit 161a needs to be provided to surround it to ensure that the non-Newtonian fluid 16b does not flow out and pollute other film layers. Optionally, the retaining wall unit 161a is made of polyimide PI. Figure 4 As shown, in the process, the barrier wall unit 161a array is first coated on the common electrode layer 11 so that the thickness around it is higher than the thickness in the middle, and then the non-Newtonian fluid 16b is sprayed into each barrier wall unit 161a, and finally a layer of polyimide PI is coated to encapsulate the non-Newtonian fluid 16b in each barrier wall unit 161a.

[0046] In addition, the fluid unit 161 will not block the color-resistance unit 131 , and the light emitted from the light-emitting element on one side of the array substrate 2 can penetrate the color-resistance unit 131 without any light loss, thereby not losing light transmittance.

[0047] Furthermore, if Figure 4 As shown, the non-Newtonian fluid 16b is also doped with a black body material 16c, and the black body material 16c includes carbon nanotubes. The carbon nanotubes can absorb light, prevent light from penetrating, and improve the contrast of the liquid crystal display panel. In addition, the height of the fluid unit 161 determines the viewing angle of the outgoing light, and the higher the height of the fluid unit 161, the smaller the viewing angle of the outgoing light, thereby increasing the anti-peeping function of the liquid crystal display panel.

[0048] Optionally, the angle of view θ of the outgoing light is in the range of 30° to 90°. For example, in a display panel in a vehicle cockpit, in order to prevent the windshield from reflecting and affecting driving safety, the angle of view of the outgoing light needs to be limited; for example, in an application where anti-peeping is required, such as a display panel behind an aircraft seat, the angle of view of the outgoing light can be limited; the angle of view θ of the outgoing light is in the range of 30° to 90°, which can meet various occasions where the angle of view of the outgoing light is limited.

[0049] Third embodiment

[0050] like Figure 5 As shown, the third embodiment of the present application provides a color filter substrate 1, which has a similar structure to the color filter substrate 1 shown in the first embodiment, except that the position of the non-Newtonian fluid layer 16 is different.

[0051] Specifically, the non-Newtonian fluid layer 16 is located between the planarization layer 14 and the plurality of support pillars 15. The planarization layer 14 is a plane, and the non-Newtonian fluid layer 16 is located between the planarization layer 14 and the plurality of support pillars 15. Since the non-Newtonian fluid layer 16 is arranged close to the plurality of support pillars 15, the protection capability of the support pillars 15 can be increased, the external impact force can be effectively blocked, the support pillars 15 can be prevented from being over-compressed, the friction between the support pillars 15 and the electronic devices on one side of the array substrate 2 can be reduced, the support pillars 15 can be prevented from being damaged, and the uneven display of the picture can be improved.

[0052] Fourth embodiment

[0053] like Figure 6 As shown, the fourth embodiment of the present application provides a color filter substrate 1, which has a similar structure to the color filter substrate 1 shown in the third embodiment, except that the non-Newtonian fluid layer 16 is not laid in an entire layer between the common electrode layer 11 and the color resist layer 13 and the light shielding layer 12.

[0054] Specifically, since the entire non-Newtonian fluid layer 16 will lose some light transmittance, in this embodiment, the non-Newtonian fluid layer 16 only covers the area corresponding to the shading unit 121, and the area corresponding to the color resist unit 131 is left blank to reduce the loss of light transmittance.

[0055] like Figure 6 As shown, the non-Newtonian fluid layer 16 includes a plurality of fluid units 161, which are arranged in parallel or crosswise, and the orthographic projection of the fluid unit 161 on the base substrate 10 falls into the orthographic projection of the light shielding unit 121 on the base substrate 10. Each fluid unit 161 includes a hollow retaining wall unit 161a and a non-Newtonian fluid 16b contained in the retaining wall unit 161a.

[0056] Since the non-Newtonian fluid 16b is fluid, a retaining wall unit 161a needs to be provided to surround it to ensure that the non-Newtonian fluid 16b does not flow out and pollute other film layers. Optionally, the retaining wall unit 161a is made of polyimide PI. Figure 6 As shown, in the process, the barrier wall unit 161a array is first coated on the common electrode layer 11 so that the thickness around it is higher than the thickness in the middle, and then the non-Newtonian fluid 16b is sprayed into each barrier wall unit 161a, and finally a layer of polyimide PI is coated to encapsulate the non-Newtonian fluid 16b in each barrier wall unit 161a.

[0057] In addition, the fluid unit 161 will not block the color-resistance unit 131 , and the light emitted from the light-emitting element on one side of the array substrate 2 can penetrate the color-resistance unit 131 without any light loss, thereby not losing light transmittance.

[0058] Furthermore, the non-Newtonian fluid 16b is doped with a black body material 16c, and the black body material 16c includes carbon nanotubes. The carbon nanotubes can absorb light, prevent light from penetrating, and improve the contrast of the liquid crystal display panel. In addition, the height of the fluid unit 161 determines the viewing angle of the outgoing light, and the higher the height of the fluid unit 161, the smaller the viewing angle of the outgoing light, thereby increasing the anti-peeping function of the liquid crystal display panel.

[0059] Optionally, the angle of view θ of the outgoing light is in the range of 30° to 90°. For example, in a display panel in a vehicle cockpit, in order to prevent the windshield from reflecting and affecting driving safety, the angle of view of the outgoing light needs to be limited; for example, in an application where anti-peeping is required, such as a display panel behind an aircraft seat, the angle of view of the outgoing light can be limited; the angle of view θ of the outgoing light is in the range of 30° to 90°, which can meet various occasions where the angle of view of the outgoing light is limited.

[0060] like Figure 7 As shown, the embodiment of the present application also provides a liquid crystal display panel 100 and a display device, wherein the liquid crystal display panel 100 includes an array substrate 2, any color filter substrate 1 as described above, and a liquid crystal layer 3 disposed between the array substrate 2 and the color filter substrate 1. The liquid crystal layer 3 includes a plurality of liquid crystal molecules, which are generally rod-shaped and can flow like a liquid, but also have certain crystal characteristics. When the liquid crystal molecules are in an electric field, their arrangement direction will change according to the change of the electric field.

[0061] In the box manufacturing process of the liquid crystal display panel, alignment films are usually prepared on the opposite surfaces of the array substrate 2 and the color filter substrate 1 respectively. The alignment films are used to limit the orientation of the liquid crystal molecules in the liquid crystal layer 3. Then, a sealing frame glue is applied to the non-display area of ​​the array substrate 2 and liquid crystal is dripped into it. Then, the array substrate 2 and the color filter substrate 1 are bonded together under a vacuum state. Finally, the frame glue is cured by ultraviolet irradiation to complete the packaging between the array substrate 2 and the color filter substrate 1.

[0062] Since the liquid crystal display panel 100 is a non-emissive light receiving element, it needs to be provided with a light source by a backlight module 200 disposed on one side of its backlight surface. The liquid crystal display panel 100 controls the rotation of the liquid crystal molecules of the liquid crystal layer 3 by applying a driving voltage to the pixel electrodes of the array substrate 2 and the common electrode layer 11 of the color filter substrate 1, so as to refract the light provided by the backlight module 200 to produce a picture. In order to display a color picture, a thin film transistor array is usually prepared on the array substrate 2 to drive the rotation of the liquid crystal molecules, and a color resist layer 13 is disposed on one side of the color filter substrate 1 to control the display of each sub-pixel Px.

[0063] It should be noted that the technical solutions of the liquid crystal display panel provided in each embodiment of the present application can be widely used in various liquid crystal display panels, such as TN (Twisted Nematic) display panel, IPS (In-Plane Switching) display panel, VA (Vertical Alignment) display panel, and MVA (Multi-Domain Vertical Alignment) display panel.

[0064] It should be easily understood that “on,” “above,” and “over” in this application should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above something” or “over,” but also may include the meaning of “above something” or “over” with no intervening features or layers therebetween (i.e., directly on something).

[0065] The term "substrate substrate" as used herein refers to the material on which subsequent material layers are added. The substrate substrate itself can be patterned. The material added on top of the substrate substrate can be patterned, or can remain unpatterned. In addition, the substrate substrate can include a wide range of materials, such as silicon, germanium, gallium arsenide, indium phosphide, etc. Alternatively, the substrate substrate can be made of a non-conductive material (e.g., glass, plastic, or sapphire wafer, etc.).

[0066] The term "layer" used in the text may refer to a material portion including an area with a certain thickness. A layer may extend over the entire underlying structure or overlying structure, or may have a range smaller than the range of the underlying or overlying structure. In addition, a layer may be an area of ​​a homogeneous or inhomogeneous continuous structure, the thickness of which is less than the thickness of the continuous structure. For example, a layer may be located between the top surface and the bottom surface of the continuous structure or between any paired lateral planes at the top surface and the bottom surface. A layer may extend laterally, vertically and / or along a tapered surface. A substrate substrate may be a layer, may include one or more layers therein, and / or may have one or more layers located thereon, above it and / or below it. A layer may include multiple layers. For example, an interconnect layer may include one or more conductors and a contact layer (forming contacts, interconnects and / or vias therein) and one or more dielectric layers.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
