Description

Technical Field

[0001] The present disclosure belongs to the field of display technology, and particularly relates to a color film substrate, a method for manufacturing the color film substrate, a display panel, and a display device. Background Art

[0002] Under-screen photosensitive technology (for example, under-screen camera technology or under-screen fingerprint technology) is the key to realizing full-screen display devices such as mobile phones. However, the light transmittance of the display panel corresponding to the photosensitive element (for example, camera or fingerprint sensor) is difficult to meet the requirements of high-definition camera and high-precision fingerprint recognition, resulting in poor under-screen photosensitive technology, which is prone to poor camera imaging quality or insensitive fingerprint recognition. Summary of the invention

[0003] The purpose of the present disclosure is to provide a color film substrate, a method for manufacturing a color film substrate, a display panel and a display device, which can improve the photosensitivity effect under the screen while realizing a full screen.

[0004] In a first aspect, the present disclosure provides a color filter substrate, comprising a substrate, wherein a display area of ​​the substrate comprises a photosensitive display area corresponding to a photosensitive element, the photosensitive display area comprises a plurality of color filter areas arranged at intervals and a spacing area between adjacent color filter areas, a color filter portion is arranged on the color filter area of ​​the photosensitive display area,

[0005] At least part of the spacing area of ​​the photosensitive display area is an adjustment spacing area, the adjustment spacing area is provided with an adjustment structure, and the color filter substrate further comprises a flat layer, the flat layer is formed on a side of the color resistance part and the adjustment structure away from the substrate;

[0006] The adjustment spacing area includes a first area and a second area arranged horizontally, the adjustment structure includes a first electrode located in the first area and a light-shielding magnetic fluid at least partially located in the second area, and the filling thickness of the light-shielding magnetic fluid in the second area is less than the thickness between the planar layer and the substrate;

[0007] When the first electrode is in a power-off state, the light-shielding magnetic fluid completely covers the second area; when the first electrode is in a power-on state, the light-shielding magnetic fluid is affected by the magnetic field of the first electrode to flow, so that at least part of the second area is not covered by the light-shielding magnetic fluid.

[0008] A second aspect of the present disclosure provides a method for manufacturing any one of the aforementioned color filter substrates, the manufacturing method comprising:

[0009] A substrate is provided, wherein a display area of ​​the substrate comprises a photosensitive display area for being opposite to a photosensitive element, the photosensitive display area comprises a plurality of color filter areas arranged at intervals and a spacing area between adjacent color filter areas, at least part of the spacing areas of the photosensitive display area are adjustment spacing areas, and the adjustment spacing areas comprise a first area and a second area arranged horizontally;

[0010] forming an electrode group on the adjustment interval area, wherein the electrode group at least includes a first electrode located in the first area;

[0011] A light shielding portion is formed on the spacing area where the electrode group is not formed;

[0012] A light-shielding magnetic fluid is formed on the adjustment spacer area, and at least a portion of the light-shielding magnetic fluid is located in the second area;

[0013] forming a color filter portion on the color filter area;

[0014] A flat layer is formed on the side of the color resist portion, the light shielding portion, the first electrode and the light shielding magnetic fluid away from the substrate. The flat layer is in contact with the color resist portion, the light shielding portion and the first electrode and has a gap with the light shielding magnetic fluid.

[0015] A third aspect of the present disclosure provides a display panel, comprising any one of the color filter substrates described above and an array substrate arranged in a box with the color filter substrate.

[0016] A fourth aspect of the present disclosure provides a display device, comprising the aforementioned display panel and a photosensitive element, wherein the photosensitive element is disposed on a side of the array substrate away from the color film substrate and is arranged corresponding to the photosensitive display area.

[0017] The disclosed solution has the following beneficial effects:

[0018] The present disclosure adjusts the state of the first electrode of the adjustment structure (including the energized state and the non-energized state, the non-energized state is the power-off state), thereby changing the position of the light-shielding magnetic fluid in the adjustment interval area, and then adjusting the second area of ​​the adjustment interval area between the light-shielding and light-transmitting states to adapt to the working state of the photosensitive element. For example, when the photosensitive element is started, the first electrode is in the energized state, and the light-shielding magnetic fluid gathers under the action of the magnetic field generated by the first electrode, so that at least part of the second area is not covered by the light-shielding magnetic fluid, and the second area not covered by the light-shielding magnetic fluid allows light to pass through, thereby increasing the transmittance of the corresponding area when the under-screen photosensitive element is started, ensuring the under-screen photosensitive effect, and when the photosensitive element is not started, the first electrode is in the power-off state, then the light-shielding magnetic fluid completely covers the second area to prevent light from passing through the second area, thereby improving the light-shielding effect of the corresponding area when the under-screen photosensitive element is not started, thereby improving the overall display effect.

[0019] In addition, the adjustment structure of the present scheme adjusts the position of the light-shielding magnetic fluid between the adjustment interval areas by utilizing the magnetic matching relationship between the electrode and the light-shielding magnetic fluid. This magnetic matching method can not only achieve switching between light-shielding and light-transmitting, but also simplify the design of the adjustment structure and reduce the design cost.

[0050] Embodiment 1

[0051] The disclosed embodiments provide a color film substrate that can be applied to liquid crystal display panels, but is not limited thereto, and can also be applied to panels using COE technology (i.e., a technology in which a color filter is placed on a thin film package), depending on the specific circumstances.

[0052] Combination Figure 1 and Figure 2 As shown, the color filter substrate 1 of this embodiment may include a substrate 10 and a color resist layer. The substrate 10 may include a display area A and a non-display area B arranged around the display area A. Further, the display area A of the substrate 10 may include a plurality of spaced color resist areas and a spacer area between adjacent color resist areas. The color resist layer may include a plurality of spaced color resist portions 11. Each color resist portion 11 is formed on a color resist area. The color resist portion 11 is used to enable the display panel including the color filter substrate 1 of this embodiment to achieve color display.

[0053] For example, the plurality of color resist portions 11 of the color filter substrate 1 may include a plurality of colors, such as red, green, blue, etc., but not limited thereto, and the color of the color resist portion 11 may be designed according to actual display requirements.

[0054] Among them, since the spacing area between two adjacent rows of color filter areas in the first direction Y (which can be understood as the column direction) of the color filter substrate 1 is usually used to connect with the array substrate 3 (such as Figure 4The row gap (not shown in the figure) on the array substrate 3 corresponds to the row gap (not shown in the figure), and the spacing area between two adjacent columns of color filter areas in the second direction X (which can be understood as the row direction) is usually used to correspond to the column gap (not shown in the figure) on the array substrate 3. This row gap is mainly used to arrange structures such as scan lines and transistors (not shown in the figure), and the column gap is mainly used to arrange structures such as data lines (not shown in the figure). Therefore, the column gap of the array substrate 3 is smaller than its row gap. Correspondingly, reference Figure 3 As shown, in the color filter substrate 1 , the interval h1 between two adjacent rows of color filter regions in the first direction Y is greater than the interval h2 between two adjacent columns of color filter regions in the second direction X.

[0055] It should be understood that the first direction Y and the second direction X intersect, and further, may be perpendicular to each other.

[0056] Specifically, the ratio of the interval h1 between two adjacent rows of color filter areas in the first direction Y to the interval h2 between two adjacent columns of color filter areas in the second direction X is about 10 times. For example, the interval h1 between two adjacent rows of color filter areas in the first direction Y may be at the level of 100 μm, and the interval h2 between two adjacent columns of color filter areas in the second direction X may be at the level of 10 um. However, it should be understood that the interval h1 between two adjacent rows of color filter areas in the first direction Y is not limited to the level of 100 μm, and the interval h2 between two adjacent columns of color filter areas in the second direction X is not limited to the level of 10 um, and they may float around these values ​​as long as the design requirements of the display panel can be met.

[0057] In this embodiment, in order to realize a full screen, the under-screen photosensitive technology can be used, combined with Figure 1 , Figure 3 and Figure 5 As shown, the area in the display area A of the substrate 10 corresponding to the photosensitive element 2 can be defined as a photosensitive display area A1. The photosensitive display area A1 has a plurality of spaced-apart color filter areas and a spacer area between adjacent color filter areas. A color filter portion 11 is provided on the color filter area of ​​the photosensitive display area A1. That is to say, in addition to being used to realize the photosensitivity function, the photosensitive display area A1 can also be used to realize the display function.

[0058] In addition, combined Figure 1 , Figure 3 and Figure 5 As shown, the area in the display area A of the substrate 10 that does not correspond to the photosensitive element 2 can be defined as a main display area A2. The main display area A2 can be adjacent to the photosensitive display area A1. The main display area A2 also has a plurality of spaced-apart color filter areas and a spacer area between adjacent color filter areas. A color filter portion 11 is also provided on the color filter area of ​​the main display area A2. That is to say, this main display area A2 is used to realize a display function.

[0059] The distribution density of the color resist portion 11 in the main display area A2 may be equal to the distribution density of the color resist portion 11 in the photosensitive display area A1, so that the overall display uniformity of the display area A is ensured while reducing the design cost.

[0060] In addition, if Figure 1 As shown, the main display area A2 can be set in a whole circle around the photosensitive display area A1, but is not limited to this. At least part of the boundary of the photosensitive display area A1 can be connected to the non-display area B, and the rest of the boundary can be connected to the main display area A2, etc., depending on the specific display product requirements.

[0061] It should be understood that the display area of ​​the main display area A2 is usually larger than the display area of ​​the photosensitive display area A1, so as to improve the display effect of the entire display area A while realizing the under-screen photosensitive technology.

[0062] In this embodiment, in order to increase the light transmittance at the corresponding area (photosensitive display area A1) when the under-screen photosensitive element 2 is activated, Figure 2 and Figure 3 As shown, an adjustment structure may be provided on at least part of the spacing area of ​​the photosensitive display area A1, and the spacing area provided with the adjustment structure may be defined as the adjustment spacing area; it should be understood that the spacing area of ​​the main display area A2 and the spacing area in the photosensitive display area A1 where no adjustment structure is provided are both provided with a shading portion 12, and the material of the shading portion 12 may be an insulating resin material, specifically a black insulating resin material.

[0063] In this embodiment, the adjustment interval area may include a first area and a second area arranged horizontally. Figure 2 and Figure 3 As shown, the adjustment structure may include a light-shielding magnetic fluid 13 and a first electrode 14, wherein the first electrode 14 is located in the first area, and at least part of the light-shielding magnetic fluid 13 is located in the second area, wherein the light-shielding magnetic fluid 13 has fluidity, and in order to prevent the light-shielding magnetic fluid 13 from flowing out of the color filter substrate 1, a flat layer 15 may be formed after the adjustment structure is formed, as shown in FIG. Figure 2 As shown, that is, the color filter substrate 1 may further include a planar layer 15 , and the planar layer 15 is formed on a side of the color resist portion 11 and the adjustment structure away from the substrate 10 .

[0064] refer to Figure 2 As shown, the filling thickness of the light-shielding magnetic fluid 13 in the second region is less than the thickness between the flat layer 15 and the substrate 10, so that the light-shielding magnetic fluid 13 can flow between the flat layer 15 and the substrate 10. The first electrode 14 has an on and off state, such as Figure 5 As shown, the light-shielding magnetic fluid 13 is used to completely cover the second area when the first electrode 14 is in the off state. Figure 6As shown, the light-shielding magnetic fluid 13 is also used to flow under the action of the magnetic field from the first electrode 14 when the first electrode 14 is in a powered-on state, so that at least part of the second area is not covered by the light-shielding magnetic fluid 13 .

[0065] The present disclosure adjusts the state of the first electrode 14 in the adjustment structure (including the energized state and the non-energized state, the non-energized state is the power-off state), thereby changing the position of the light-shielding magnetic fluid 13 in the adjustment interval area, and then adjusting the second area of ​​the adjustment interval area between the light-shielding state and the light-transmitting state to adapt to the working state of the photosensitive element 2, for example, Figure 6 As shown, when the photosensitive element 2 is started, the first electrode 14 is in a powered-on state, and the light-shielding magnetic fluid 13 is gathered under the action of the magnetic field generated by the first electrode 14, so that at least part of the second area is not covered by the light-shielding magnetic fluid 13, and the second area not covered by the light-shielding magnetic fluid 13 allows light to pass through, thereby increasing the light transmittance of the corresponding area when the under-screen photosensitive element 2 is started, ensuring the under-screen photosensitivity effect, and as shown in FIG. Figure 5 As shown, when the photosensitive element 2 is not started, the first electrode 14 is in a power-off state, and the shading magnetic fluid 13 completely covers the second area to prevent light from passing through the second area. This improves the shading effect of the corresponding area when the photosensitive element 2 under the screen is not started, thereby improving the overall display effect.

[0066] In addition, the adjustment structure of the present scheme adjusts the position of the light-shielding magnetic fluid 13 between the adjustment interval areas by utilizing the magnetic matching relationship between the electrode and the light-shielding magnetic fluid 13. This magnetic matching method can not only realize the switching between light-shielding and light-transmitting, but also simplify the design of the adjustment structure and reduce the design cost.

[0067] In this embodiment, the first electrode 14 can completely cover the first area, that is, the first area can be understood as the area in the adjustment spacer area for forming the first electrode 14, and the light-shielding magnetic fluid 13 is completely located in the second area and can flow on the second area, that is, the second area can be understood as the area in the adjustment spacer area for filling the light-shielding magnetic fluid 13.

[0068] Among them, the first electrode 14 can be a non-transparent conductor, so as to ensure the shading effect when the photosensitive element 2 is not turned on, that is: in addition to the area covered by the shading magnetic fluid 13 in the adjustment structure, the position where the first electrode 14 is located can also achieve the shading function.

[0069] For example, when the first electrode 14 is energized to generate a magnetic field, Figure 6As shown, the light-shielding magnetic fluid 13 can gather in the direction close to the first electrode 14, that is, when the first electrode 14 is powered on, a magnetic attraction is generated between the light-shielding magnetic fluid 13 and the first electrode 14, so as to attract the light-shielding magnetic fluid 13 to gather in the direction where it is located. And the first electrode 14 can be a metal conductor, such as one of non-transparent conductors such as iron, copper, and aluminum, so as to enhance the magnetic field generated when it is powered on, so as to better gather at the position where the first electrode 14 is located, so that as many areas as possible in the second zone are not covered by the light-shielding magnetic fluid 13, thereby improving the light transmittance, and then improving the photosensitivity of the photosensitive element 2.

[0070] In this embodiment, when the first electrode 14 is in the power-off state: Figure 2 As shown, there is a cavity S between the light-shielding magnetic fluid 13 and the flat layer 15 to ensure the fluidity of the light-shielding magnetic fluid 13. It should be understood that Figure 2 After the color filter substrate 1 is inverted and aligned with the array substrate 3, if the first electrode 14 is in a power-off state, the light-shielding magnetic fluid 13 will accumulate on the flat layer 15 under the action of its own gravity. Figure 5 As shown, at this time, there is a cavity S between the light-shielding magnetic fluid 13 and the substrate 10; and when the first electrode 14 is in the energized state: there is a cavity S between the area of ​​the second region not covered by the light-shielding magnetic fluid 13 and the flat layer 15, and this cavity S has no light-shielding object. It should be understood that when Figure 2 After the color filter substrate 1 is inverted and matched with the array substrate 3, if the first electrode 14 is in a powered state, the light-shielding magnetic fluid accumulated on the flat layer 15 will gather toward the side close to the first electrode 14 under the action of its own gravity, so that there is no light-shielding magnetic fluid 13 filled between the second area and the flat layer, that is, the area not filled with the light-shielding magnetic fluid 13 is a cavity S, as shown in FIG. Figure 6 As shown, light can pass through better, thereby achieving the purpose of increasing light transmittance to ensure the photosensitivity quality of the under-screen photosensitive element 2. For example, when the photosensitive element 2 is a camera, the imaging quality of the under-screen camera can be improved.

[0071] Among them, since it is mentioned above that the interval h1 between two adjacent rows of color resistance areas in the first direction Y is greater than the interval h2 between two adjacent columns of color resistance areas in the second direction X, in order to reduce the processing difficulty of the adjustment structure, the adjustment structure can be set in the spacing area between two adjacent rows of color resistance areas in the first direction Y in the photosensitive display area A1, that is, the adjustment spacing area is located between two adjacent rows of color resistance areas in the first direction Y.

[0072] In addition, since the interval between two adjacent rows of color resistance areas in the first direction Y is relatively large, a larger area in the adjustment interval area can be designed as an area for the light-shielding magnetic fluid 13 to flow, that is, a second area with a larger area can be designed. In this way, when the photosensitive element 2 is started, the adjustment structure can also form a larger light-transmitting area (that is, the area in the second area that is not covered by the light-shielding magnetic fluid 13 when the photosensitive element 2 is started), thereby improving the transmittance of the adjustment structure and then improving the photosensitivity of the photosensitive element 2.

[0073] For example, combined with Figure 2 and Figure 3 As shown, the first electrode 14 and the light-shielding magnetic fluid 13 in the adjustment structure are arranged horizontally in the first direction Y. It can also be understood that the first area and the second area of ​​the adjustment interval area are arranged horizontally in the first direction Y. This can increase the area of ​​the first electrode 14 so that a stronger magnetic field can be generated when the first electrode 14 is energized, thereby driving the light-shielding magnetic fluid 13 to quickly and stably gather at the designated position to ensure the photosensitivity effect.

[0074] Furthermore, combined with Figure 2 and Figure 3 As shown, the second zone is provided with first zones on opposite sides in the first direction Y, and a first electrode 14 is formed on each first zone. The first electrodes 14 located on opposite sides of the second zone in the first direction Y and the shading portions 12 located on opposite sides of the second zone in the second direction X form a cavity for accommodating the light-shading magnetic fluid 13. By utilizing the shading portion 12 and the first electrode 14 to jointly form a cavity for accommodating the light-shading magnetic fluid 13, the area of ​​the electrode can be appropriately reduced, thereby reducing the electrical loss when the photosensitive element 2 is started.

[0075] However, it should be understood that the present embodiment is not limited to providing the first zone only on two opposite sides of the first direction Y of the second zone. The first zone may also be provided around the second zone. In other words, the first electrode 14 may also be an annular electrode, which completely surrounds the second zone to form a cavity for accommodating the light-shielding magnetic fluid 13. The cavity has better sealing properties. In addition, when the first electrode 14 is manufactured, the light-shielding magnetic fluid 13 may be directly filled into the cavity surrounded by the first electrode 14 itself.

[0076] For example, Figure 2 As shown, the first electrode 14 of this embodiment contacts the substrate 10 and the flat layer 15 at both ends in the thickness direction Z, respectively. At this time, the thickness of the first electrode 14 can be understood as the thickness of the entire adjustment structure.

[0077] Among them, combined Figure 3 , Figure 4 and Figure 7As shown, the first electrode 14 as a whole can extend in the second direction X, and a part of the first electrode 14 can extend to the non-display area B of the substrate 10 and form a first adapter 140. This first adapter 140 can be connected to the conductive connection point 31 on the array substrate 3 through the conductive glue 16. The conductive connection point 31 can be connected to the electrode signal line 32 located on the periphery of the non-display area B on the array substrate 3, and finally provide a voltage control signal through the integrated circuit 4 or FPC (flexible circuit board 5) in the binding area B1 (this binding area B1 is a part of the non-display area B) on the array substrate 3.

[0078] In this embodiment, the first electrodes 14 on the opposite sides of the second area in the first direction Y can be controlled together to write the same voltage, that is, the two first electrodes 14 located in the second area in the first direction Y can be connected to the same conductive connection point 31 on the array substrate 3 through the conductive glue 16, which can reduce the design difficulty of the array substrate 3 and the control difficulty of the integrated circuit 4 and the FPC.

[0079] In addition, the first electrodes 14 located on the opposite sides of the second area are controlled together, so that when the photosensitive element 2 is started, the voltages of the first electrodes 14 located on the opposite sides of the second area in the adjustment structure can be the same, and the same magnetic field is generated. In this way, when the photosensitive element 2 is started, the light-shielding magnetic fluid 13 can move to the first electrodes 14 on both sides respectively, so that the middle area of ​​the adjustment structure is not covered by the light-shielding magnetic fluid 13, that is, the middle area of ​​the adjustment structure is a light-transmitting area, so that light can pass through the adjustment structure more evenly and be incident on the photosensitive element 2, thereby improving the photosensitivity effect.

[0080] However, the present invention is not limited to this, and the two first electrodes 14 located in the second area in the first direction Y can also be independently controlled, and the same voltage can be written into the two first electrodes 14, or different voltages can be written into the two first electrodes 14, depending on the specific situation; specifically, the first adapter portions 140 of the two first electrodes 14 can be connected to different conductive connection points 31 on the array substrate 3 through anisotropic conductive glue, and each conductive connection point 31 can be respectively connected to an electrode signal line 32 located in the non-display area B on the array substrate 3.

[0081] In addition, if Figure 3 As shown, the first electrode 14 is fitted with a plurality of color resist portions 11 adjacent thereto and located in the photosensitive display area A1, that is, the size of the adjustment structure in the second direction X can correspond to the plurality of color resist portions 11, which can increase the light-transmitting area of ​​the adjustment structure when the photosensitive element 2 is activated, thereby improving the light transmittance.

[0082] In this embodiment, the light-shielding magnetic fluid 13 can be a black magnetic ink, which includes 60% to 80% of pigment, 15% to 35% of connecting material, and 5% of additives. Further, the black magnetic ink is composed of 60% to 80% of pigment, 15% to 35% of connecting material, and 5% of additives. The pigment in the black magnetic ink is the main component, so that the black magnetic ink is black and has magnetism. If the pigment accounts for too much, the overall fluidity of the black magnetic ink will be affected. If the pigment accounts for too little, the magnetic characteristics of the black magnetic ink will not be significant, resulting in the inability to accurately control the flow change of the black magnetic ink after the electrode is energized. After mixing with the connecting material, the pigment has better fluidity after being affected by the magnetic field. If the connecting material accounts for too much, the pigment accounts for less than the same period last year, which will cause the black magnetic ink to be unable to be controlled by the magnetic field. If the connecting material accounts for too little, the black magnetic ink cannot quickly flow and return to its initial state after the magnetic field is removed. The additive plays a lubricating role, and together with the connecting material, the pigment does not agglomerate.

[0083] For example, the pigment in the black magnetic ink is one of black iron oxide (Fe3O4) or brown iron oxide (Fe2O3), which is a magnetic pigment, and its particles are needle-shaped crystals less than 1um, and the pigment can be evenly arranged in a magnetic field; the binder is one of the synthetic resins such as alkyd resin, polyurethane, epoxy resin, acrylamide, polyvinyl acetate, vinyl chloride-acetic acid copolymer, polyvinyl butyral, polyethylene ethyl ether, nitrocellulose, polyurethane resin, etc., which is used to ensure the fluidity and adhesion of the black magnetic ink; the additive is one of the silane or ferrite substances, which is used to ensure the uniform dispersion of the magnetic pigment in the binder.

[0084] In the embodiments of the present disclosure, Figure 2 As shown, the ratio of the filling thickness d1 of the light-shielding magnetic fluid 13 in the second zone in the adjustment spacer to the thickness d between the flat layer 15 and the substrate 10 is in the range of 1 / 3 to 2 / 3. In other words, the ratio of the filling thickness d1 of the light-shielding magnetic fluid 13 during the manufacturing process to the thickness d of the first electrode 14 is in the range of 1 / 3 to 2 / 3, such as 1 / 3, 1 / 2, 2 / 3, etc., wherein, if the light-shielding magnetic fluid 13 is filled too little, the adjustment structure cannot play a good light-shielding effect when the photosensitive element 2 is not started, and if it is filled too much, the light-transmitting area of ​​the adjustment structure is smaller when the photosensitive element 2 is started.

[0085] In the embodiments of the present disclosure, Figure 2As shown, the width w of the first electrode 14 can range from 0.5μm to 2μm, for example: 0.5μm, 1μm, 1.5μm, 2μm, etc., so as to ensure the magnetic field strength generated by the first electrode 14 when the photosensitive element 2 is started, so that the shading magnetic fluid 13 can quickly gather to the position close to the first electrode 14, so that at least part of the second area in the adjustment interval is not covered by the shading magnetic fluid 13, and at the same time, the excessive area of ​​the adjustment interval occupied by the first electrode 14 can be reduced, that is: the proportion of the first area in the adjustment interval is reduced, and the proportion of the second area is increased, and then the area of ​​the second area not covered by the shading magnetic fluid 13 can be increased, thereby improving the transmittance of the adjustment structure when the photosensitive element 2 is started.

[0086] It should be understood that the main application state of the color film substrate 1 of this embodiment is a horizontal placement (i.e., parallel to the substrate 10) state or a small-angle tilted placement (having a small angle with the substrate 10) state to ensure that the light-shielding magnetic fluid 13 can completely cover the second area when the first electrode 14 is not energized (i.e., in a power-off state), thereby ensuring that the adjustment structure has good light-shielding performance when the photosensitive element 2 is not turned on.

[0087] Embodiment 2

[0088] Based on the structure of the color filter substrate 1 mentioned in the first embodiment, the second embodiment provides a method for manufacturing the color filter substrate 1. It should be understood that the specific structure of the color filter substrate 1 can refer to the content described in the first embodiment, and no repeated limitation is made here. The method for manufacturing the color filter substrate 1 of the first embodiment can be described in detail below in conjunction with the accompanying drawings.

[0089] like Figure 8 As shown, the method for manufacturing the color filter substrate 1 may include:

[0090] Step S100, providing a substrate 10;

[0091] Step S102: forming an electrode group on the adjustment spacing area of ​​the substrate 10, wherein the electrode group at least includes a first electrode 14 located in the first area, Fig. 9 As shown;

[0092] Step S104: forming a light shielding portion 12 on the spacer area where no electrode group is formed, referring to Fig.10 As shown;

[0093] Step S106: forming a light-shielding magnetic fluid 13 on the adjustment spacing area, wherein at least a portion of the light-shielding magnetic fluid 13 is located in the second area. Fig.10 As shown;

[0094] Step S108: forming a color filter portion 11 on the color filter area, referring to Fig.11 As shown;

[0095] Step S110, forming a flat layer 15 on the side of the color block portion 11, the light shielding portion 12, the first electrode 14 and the light shielding magnetic fluid 13 away from the substrate 10, the flat layer 15 is in contact with the color block portion 11, the light shielding portion 12, the first electrode 14, and has a gap with the light shielding magnetic fluid 13, refer to Figure 2 shown.

[0096] Among them, in step S102, when the first electrode 14 is formed only on two opposite sides in the first direction Y of the second zone, step S104 can be performed first, so that the shading portion 12 and the first electrode 14 first form a cavity for accommodating the shading magnetic fluid 13, and then step S106 is performed, that is: filling the light-shielding magnetic fluid 13 into the cavity surrounded by the light-shielding portion 12 and the first electrode 14.

[0097] It should be understood that in step S102, when a ring-shaped and closed second electrode is formed around the second area, step S104 may be performed first and then step S106, but is not limited thereto. Step S106 may also be performed first and then step S104, depending on the specific situation.

[0098] In addition, it should be noted that step S108 may be executed after step S104 and step S106, but is not limited thereto, and may also be executed before step S104 and step S106, depending on the specific circumstances.

[0099] In this embodiment, before step S110, the method for manufacturing the color filter substrate 1 further includes: step S1091, disposing a magnetic driving member 6 on a side of the substrate 10 away from the light-shielding magnetic fluid 13, wherein the magnetic driving member 6 provides a magnetic repulsive force to the light-shielding magnetic fluid 13 to drive the light-shielding magnetic fluid 13 to move in a direction away from the substrate 10, so that the light-shielding magnetic fluid 13 moves to a point where its surface away from the substrate 10 is flush with the surface of the first electrode 14 away from the substrate 10, with reference to Fig.12 As shown; it should be understood that when performing step S110 to form a flat layer 15 on the side of the color block portion 11, the light shielding portion 12, the first electrode 14 and the light shielding magnetic fluid 13 away from the substrate 10, the magnetic driving member 6 is not removed, and the magnetic driving member 6 still provides a magnetic repulsive force to keep the light shielding magnetic fluid 13 in a suspended state so as to be flush with the surface of the first electrode 14 away from the substrate 10, refer to Fig.13 In addition, after step S110, the method for manufacturing the color filter substrate 1 further includes: step S111, removing the magnetic repulsion of the magnetic driving member 6 to form Figure 2 The color film substrate shown.

[0100] The color film substrate 1 manufactured by this manufacturing method can, when the first electrode 14 is in the power-off state: a cavity S is formed between the light-shielding magnetic fluid 13 and the flat layer 15 to ensure the fluidity of the light-shielding magnetic fluid 13; when the first electrode 14 is in the power-on state: a cavity S is formed between the area of ​​the second zone not covered by the light-shielding magnetic fluid 13 and the flat layer 15, and this cavity S can better allow light to pass through to improve the photosensitivity effect.

[0101] Among them, when the light-shielding magnetic fluid 13 is filled, the size of its gravity N can be known according to the filling amount. The magnetic driving component 6 is energized to generate a repulsive force M on the light-shielding magnetic fluid 13, and this M>N. The light-shielding magnetic fluid 13 as a whole will overcome the gravity and rise. When the surface of the light-shielding magnetic fluid 13 and the surface of the first electrode 14 are flush, the power-on state of the magnetic driving component 6 is changed to make it generate a repulsive force N on the light-shielding magnetic fluid 13. At this time, the light-shielding magnetic fluid 13 is in a suspended state to keep it flush with the surface of the first electrode 14 away from the substrate 10. The rising speed and time of the light-shielding magnetic fluid 13 can be controlled by the different repulsive forces generated by the magnetic driving component 6.

[0102] Embodiment 3

[0103] The difference between the third embodiment and the second embodiment is that the adjustment structure in the third embodiment includes not only the first electrode 14 and the light-shielding magnetic fluid 13, but also the light-transmitting fluid 17. When the first electrode 14 is in the off state, the space between the light-shielding magnetic fluid 13 and the flat layer 15 is filled with the light-transmitting fluid 17. Fig.14 When the first electrode 14 is in the energized state: the second region not covered by the light-shielding magnetic fluid 13 and the flat layer 15 are filled with the light-transmitting fluid 17, such as Fig.15 shown.

[0104] In this embodiment, by providing the light-transmitting fluid 17, it is ensured that the light-shielding magnetic fluid 13 is gathered on the side of the first electrode 14 when the photosensitive element 2 is in the on state. Fig.17 As shown, the situation that the transmittance of the second area of ​​the adjustment structure decreases due to the partial movement of the light-shielding magnetic fluid 13 is avoided or alleviated. In addition, the preparation process of the color film substrate 1 with this adjustment structure can be easier to implement, that is, the preparation process of the flat layer 15 on the adjustment structure is simplified.

[0105] For example, the light-transmitting fluid 17 of the present embodiment may be transparent resin particles, the main component of which is insulating, transparent polycarbonate particles, which are lighter than the light-shielding magnetic fluid 13. When the photosensitive element 2 starts working, the first electrode 14 is energized, and the light-shielding magnetic fluid 13 is affected by the magnetic force and gathers toward the first electrode 14. The transparent resin particles are insulating materials and do not gather toward the first electrodes 14 on both sides. The movement of the light-shielding magnetic fluid 13 causes the transparent resin particles to move toward the middle area of ​​the second area, such as Fig.17 As shown, the light-shielding magnetic fluid 13 is further pushed to move toward the first electrodes 14 on both sides, so as to increase the light transmittance, so as to ensure the light-sensing quality of the photosensitive element 2 under the screen. For example, when the photosensitive element 2 is a camera, the imaging quality of the camera under the screen can be improved. When the first electrode 14 is not energized, because the mass of the light-shielding magnetic fluid 13 is greater than that of the transparent resin particles, the light-shielding magnetic fluid 13 falls to the bottom of the adjustment structure, and the transparent resin particles move to the top of the adjustment structure, so as to achieve the light-shielding effect of the display panel using the color film substrate 1 under normal working conditions.

[0106] It should be understood that, since the mass of the light-transmitting fluid 17 is lighter than that of the light-shielding magnetic fluid 13, when the color filter substrate 1 is arranged above the array substrate 3, specifically, when the flat layer 15 is located on the side of the substrate 10 close to the array substrate 3, when the first electrode 14 is in the power-off state (i.e., the photosensitive element 2 is not activated), the light-transmitting fluid 17 will be located between the light-shielding magnetic fluid 13 and the substrate 10, as shown in FIG. Fig.16 shown.

[0107] It should be understood that, except for the differences from the first embodiment mentioned above, the rest of the third embodiment can refer to the contents of the first embodiment and are not repeated here.

[0108] Embodiment 4

[0109] Based on the structure of the color filter substrate 1 mentioned in the third embodiment, the fourth embodiment provides a method for manufacturing the color filter substrate 1. It should be understood that the specific structure of the color filter substrate 1 can refer to the content described in the third embodiment and is not repeatedly limited here.

[0110] In addition, the main difference between the method for manufacturing the color filter substrate 1 of the fourth embodiment and the method for manufacturing the color filter substrate 1 of the second embodiment is that before step S110, the method for manufacturing the color filter substrate 1 of the fourth embodiment does not include step S1091, but includes: step S1092, filling the light-transmitting fluid 17 on the side of the light-shielding magnetic fluid 13 away from the substrate 10, such as Fig.18 As shown, the light-transmitting fluid 17 is flush with the surface of the first electrode 14 away from the substrate 10, and then the flat layer 15 is made. The flat layer 15 made in this way is in contact with the color resistance part 11, the light shielding part 12, the first electrode 14, and the light-transmitting fluid 17. Fig.14 shown.

[0111] In this embodiment, the light-transmitting fluid 17 is first filled on the side of the light-shielding magnetic fluid 13 away from the substrate 10, and then the flat layer 15 is made. This makes the preparation process of the color filter substrate 1 easier to implement, that is, simplifies the preparation process of the flat layer 15 on the adjustment structure.

[0112] It should be understood that, except for the differences from the second embodiment mentioned above, the rest of the fourth embodiment can refer to the contents of the second embodiment and are not repeatedly limited here.

[0113] Embodiment 5

[0114] The main difference between the fifth embodiment and the first or third embodiment is that: Fig.19 or Fig. 20 As shown, the adjustment structure of the fifth embodiment may further include a second electrode 18, which is located in the second area and is a second electrode 18 of a transparent conductor. The second electrode 18 and the first electrode 14 are horizontally spaced apart, so that the first electrode 14 and the second electrode 18 can be independently controlled, wherein the second electrode 18 is formed on the substrate 10, the thickness of the second electrode 18 is less than the thickness of the first electrode 14, and at least a portion of the light-shielding magnetic fluid 13 is filled between the second electrode 18 and the flat layer 15.

[0115] The second electrode 18 of this embodiment can be in a powered-on state when the first electrode 14 is in a powered-on state, and the second electrode 18 can be in a powered-off state when the first electrode 14 is in a powered-on state. That is, when the photosensitive element 2 is not started, the first electrode 14 is in a powered-off state, and the second electrode 18 is in a powered-on state. When the second electrode 18 is in a powered-on state, the light-shielding magnetic fluid 13 is affected by the magnetic field from the second electrode 18 to flow, so that the light-shielding magnetic fluid 13 completely covers the second area. Fig.21 As shown (or reference Fig. 22 When the photosensitive element 2 is started, the first electrode 14 is in a powered state, and the light-shielding magnetic fluid 13 is gathered under the action of the magnetic field generated by the first electrode 14, so that at least part of the second area is not covered by the light-shielding magnetic fluid 13, reference Fig.23 As shown (or reference Fig.24 (As shown) In addition, since the second electrode 18 is a transparent conductor, the second area not covered by the light-shielding magnetic fluid 13 and the second electrode 18 allow light to pass through, thereby increasing the transmittance of the corresponding area when the under-screen photosensitive element 2 is activated.

[0116] In the present embodiment, by providing the second electrode 18, it can be ensured that when the photosensitive element 2 is not started (i.e., not working), the light-shielding magnetic fluid 13 can completely cover the second area in different usage environments to play a light-shielding role. That is to say, the use environment of the color film substrate 1 of the present embodiment is not limited to horizontal placement, small-angle tilt and other usage environment states, and can also be used in a vertical use environment or a large-angle tilt use environment, that is: the color film substrate 1 of the present embodiment and the display panel having this color film substrate 1 have a wider range of applications.

[0117] For example, this light-shielding magnetic fluid 13 can be driven by the magnetic field generated by the second electrode 18 to gather toward the position close to the second electrode 18, so that the second electrode 18 and the gaps between the second electrode 18 and the first electrode 14 are completely covered by the light-shielding magnetic fluid 13, that is, the second area is completely covered by the light-shielding magnetic fluid 13, that is, when the second electrode 18 is energized, a magnetic attraction is generated between the second electrode 18 and the light-shielding magnetic fluid 13 to attract the light-shielding magnetic fluid 13 to gather in its direction.

[0118] In addition, it should be noted that, when the color film substrate 1 of the present embodiment is in a use environment state such as horizontal placement or small angle tilt, the second electrode 18 may not be energized when the photosensitive element 2 is not started. At this time, the second electrode 18 and the gap between the second electrode 18 and the first electrode 14 are completely covered by the orthographic projection of the light-shielding magnetic fluid 13 on the substrate 10. When the color film substrate 1 of the present embodiment is in a use environment state such as vertical placement or large angle tilt, the second electrode 18 needs to be energized when the photosensitive element 2 is not started to ensure that the second electrode 18 and the gap between the second electrode 18 and the first electrode 14 are completely covered by the light-shielding magnetic fluid 13.

[0119] Among them, Fig.25 As shown, the gap h3 between the first electrode 14 and the second electrode 18 ranges from 0.5μm to 1.5μm, for example: 0.5μm, 0.75μm, 1μm, 1.25μm, 1.5μm, etc., so that while ensuring that the gap between the first electrode 14 and the second electrode 18 can be independently controlled and easy to process, the gap between the second electrode 18 and the first electrode 14 can be completely covered by the shading magnetic fluid 13 when the second electrode 18 is energized, thereby ensuring the shading effect.

[0120] For example, the thickness of the second electrode 18 can range from 0.5μm to 1μm, such as: 0.5μm, 0.6μm, 0.7μm, 0.8μm, 0.9μm, 1μm, etc., so that while ensuring its light transmittance, it can also ensure the magnetic field strength generated by the second electrode 18 when the photosensitive element 2 is not started, so that the shading magnetic fluid 13 can quickly gather close to the position where the second electrode 18 is located, so that the second electrode 18 and the gap between the second electrode 18 and the first electrode 14 are completely covered by the light-shielding magnetic fluid 13, thereby ensuring the shading effect of the adjustment structure when the photosensitive element 2 is not started.

[0121] For example, Fig.26As shown, a portion of the second electrode 18 can extend to the non-display area B of the substrate 10 and form a second transition portion 180, and the second transition portion 180 of the second electrode 18 and the first transition portion 140 of the first electrode 14 are respectively connected to the conductive connection points 31 at corresponding positions in the array substrate 3, wherein the second transition portion 180 and the first transition portion 140 are arranged at intervals so that the second transition portion 180 and the first transition portion 140 can be controlled independently of each other.

[0122] Among them, Fig.26 As shown, the thickness of the first adapter portion 140 and the second adapter portion 180 can be equal, so that after the color film substrate 1 and the array substrate 3 are aligned, the first adapter portion 140 and the second adapter portion 180 can be simultaneously connected to the first conductive connection point 310 and the second conductive connection point 311 at the corresponding position of the array substrate 3 through the anisotropic conductive adhesive 19.

[0123] It should be noted that if Fig.25 As shown, the overall extension lengths of the first electrode 14 and the second electrode 18 in the second direction X may be equal.

[0124] In this embodiment, the first electrode 14 is not limited to the non-transparent conductor mentioned in the first embodiment, but may also be a transparent conductor. The first electrode 14 may be arranged on the same layer as the second electrode 18 of this embodiment. The same-layer arrangement means that the first electrode 14 and the second electrode 18 use the same transparent conductive material and are made using the same mask process. This can reduce the mask process and thus reduce costs.

[0125] It should be noted that, since the width of the first electrode 14 is relatively small, the interval between two adjacent rows of color filter areas in the first direction Y is relatively large. Specifically, the width range of the first electrode 14 mentioned in Example 1 is 0.5μm to 2μm, and the interval between two adjacent rows of color filter areas in the first direction Y can be on the order of 100μm. Therefore, when the first electrode 14 is a transparent conductor, the influence of the first electrode 14 on the shading performance of the adjustment structure is relatively small and can be ignored.

[0126] It should be understood that, except for the differences between the fifth embodiment and the first and third embodiments mentioned above, the rest of the fifth embodiment can refer to the contents of the first and third embodiments, and no repeated limitations are made here.

[0127] Embodiment 6

[0128] Based on the structure of the color filter substrate 1 mentioned in the fifth embodiment, the sixth embodiment provides a method for manufacturing the color filter substrate 1. It should be understood that the specific structure of the color filter substrate 1 can refer to the content described in the fifth embodiment and is not repeatedly limited here.

[0129] In addition, the main difference between the method for manufacturing the color filter substrate 1 of the sixth embodiment and the method for manufacturing the color filter substrate 1 of the second embodiment and the fourth embodiment is that step S102 specifically includes:

[0130] Step S1021, forming a first electrode 14 on the first region of the adjustment spacer region;

[0131] Step S1022, forming a second electrode 18 on the second area of ​​the adjustment interval area, the second electrode 18 and the first electrode 14 are arranged at intervals, referring to Fig. 27 shown.

[0132] When the first electrode 14 is a non-transparent conductor and the second electrode 18 is a transparent conductor, step S1021 may be performed first and then step S1022; or step S1022 may be performed first and then step S1021.

[0133] In addition, when the first electrode 14 and the second electrode 18 are both transparent conductors, step S1021 and step S1022 can be performed simultaneously. For example, a transparent conductive layer can be first formed on the substrate 10, and then the transparent conductive layer can be patterned to form a transparent conductive layer. Fig. 27 The structure shown.

[0134] It should be understood that, except for the differences between Embodiment 6 and Embodiment 2 and Embodiment 4 mentioned above, the rest of Embodiment 6 may refer to the contents of Embodiment 2 or Embodiment 4 and are not repeatedly limited here.

[0135] Embodiment 7

[0136] Embodiment 7 of the present disclosure provides a display panel, which includes the color filter substrate 1 described in Embodiment 1, Embodiment 3 or Embodiment 5 and an array substrate 3 arranged in a box with the color filter substrate 1 .

[0137] It should be understood that the display area A and the non-display area B of the color filter substrate 1 can be understood as the display area A and the non-display area B of the entire display panel.

[0138] For example, the display panel may be a liquid crystal display panel, that is, Figure 5 , Fig.16 , Fig.21 or Fig. 22 As shown, the display panel includes not only the color filter substrate 1 and the array substrate 3 arranged in a box, but also a liquid crystal layer (not shown in the figure) filled between the color filter substrate 1 and the array substrate 3, a frame sealing glue 7 arranged around the liquid crystal layer, and an upper polarizer 91 and a lower polarizer 92. The frame sealing glue 7 is arranged between the color filter substrate 1 and the array substrate 3 and is located in the non-display area B of the display panel. The upper polarizer 91 can be located on the side of the color filter substrate 1 away from the array substrate 3, and the lower polarizer 92 can be located on the side of the array substrate 3 away from the color filter substrate 1.

[0139] The following description will be made by taking the color filter substrate 1 described in the fifth embodiment as an example.

[0140] like Fig.26 As shown, in the non-display area B: the array substrate 3 is provided with a first conductive connection point 310 corresponding to the first transition portion 140 of the first electrode 14, and a second conductive connection point 311 corresponding to the second transition portion 180 of the second electrode 18, the first conductive connection point 310 and the second conductive connection point 311 are arranged at intervals, and the first conductive connection point 310 and the second conductive connection point 311 can be coated with anisotropic conductive glue 19 (the anisotropic conductive glue 19 is conductive up and down but not conductive left and right) to be electrically connected to the first transition portion 140 and the second transition portion 180.

[0141] refer to Figure 4 As shown, the display panel may also include a flexible circuit board 5 and an integrated circuit 4 for generating control signals. The flexible circuit board 5 or the integrated circuit 4 can be bound to the binding area B1 located in the non-display area B of the array substrate 3, wherein the first conductive connection point 310 and the second conductive connection point 311 are respectively connected to the integrated circuit 4 or the flexible circuit board 5 through independent control signal lines, and the control signals generated by the flexible circuit board 5 and the integrated circuit 4 are transmitted to the corresponding conductive connection points 31 via the control signal lines on the periphery of the array substrate 3 (located in the non-display area B), thereby realizing the control of the first electrode 14 and the second electrode 18.

[0142] In addition, if two first electrodes 14 of the adjustment structure are set and are independently controlled, two first conductive connection points 310 on the array substrate 3 can also be set, and they are connected to the integrated circuit 4 or the flexible circuit board 5 through independent control signal lines respectively. If two first electrodes 14 of the adjustment structure are set and are jointly controlled, two first conductive connection points 310 on the array substrate 3 can also be set and connected in series to be connected to the integrated circuit 4 or the flexible circuit board 5 through the same control signal line.

[0143] Embodiment 8

[0144] Embodiment 8 of the present disclosure further provides a display device, referring to Figure 5 , Fig.16 , Fig.21 or Fig. 22 As shown, it includes the display panel and the photosensitive element 2 described in the seventh embodiment.
