Description

Technical Field

[0001] The present disclosure relates to the technical field of liquid crystal panels, and in particular, to a liquid crystal panel and a manufacturing method thereof. Background Art

[0002] During the manufacturing process of the liquid crystal panel, the CF (Color Filter) substrate and the TFT (Thin Film Transistor) substrate are usually aligned in a vacuum environment. After alignment, the liquid crystal panel will enter the air environment. There is a spacer between each row of cells (i.e., the liquid crystal screen) of the liquid crystal panel. The spacer is not filled with liquid crystal, so the support is relatively weak, and the spacer is adjacent to the liquid crystal filling area between the CF substrate and the TFT substrate. Due to the change in pressure when the liquid crystal panel enters the air from the vacuum, the gap between the weakly supported spacers is likely to change, which will affect the adjacent liquid crystal filling area, causing the cell gap (gap) of the liquid crystal filling area between the CF substrate and the TFT substrate to change, resulting in color difference in the color of the liquid crystal filling area. For example, the edges of the liquid crystal cell will turn yellow. Summary of the Invention

[0014] Optionally, in the arrangement direction of each row of cells, the distance from the fourth supporting adhesive layer to the corresponding outermost cell is equal to the distance from the fourth supporting adhesive layer to the third supporting adhesive layer.

[0015] According to another aspect of the present disclosure, a method for manufacturing a liquid crystal panel is provided. The liquid crystal panel has at least one cell area, the cell area including multiple rows of cells, each row of cells having a spacer area between them. The liquid crystal panel includes a TFT substrate, a CF substrate, and a support portion. The TFT substrate and the CF substrate are disposed opposite each other. A circuit connection area for connecting a circuit is provided on the TFT substrate corresponding to the spacer area. The method includes:

[0016] Before aligning the TFT substrate and the CF substrate, the supporting portion is provided on the circuit connection area, wherein one end of the supporting portion is detachably connected to the circuit connection area, and the other end of the supporting portion is used to be connected to the first blank area on the CF substrate corresponding to the spacer area after the TFT substrate and the CF substrate are aligned.

[0017] Optionally, before aligning the TFT substrate with the CF substrate, providing the support portion on the circuit connection area includes:

[0018] A barrier coating is applied on the circuit connection area, and a first supporting adhesive layer is applied on the barrier coating, wherein one end of the first supporting adhesive layer away from the barrier coating is used to connect to the first blank area of the CF substrate, and the adhesion of the barrier coating is weaker than that of the first supporting adhesive layer, so that the barrier coating can be peeled off from the circuit connection area.

[0019] Optionally, the method further includes:

[0020] Before aligning the TFT substrate with the CF substrate, coating a third supporting adhesive layer and a fourth supporting adhesive layer on one of a third blank area on the TFT substrate and a fourth blank area on the CF substrate, wherein the third supporting adhesive layer is disposed around one of the cell areas, and a distal end of the third supporting adhesive layer is used to adhere to the other of the third blank area and the fourth blank area after the TFT substrate and the CF substrate are aligned;

Therefore, it can be avoided that the change in the gap affects the change in the gap of the liquid crystal filling area adjacent to the gap. In other words, by providing the support portion, it is beneficial to ensure that the gap in the liquid crystal filling area between the CF substrate and the TFT substrate remains uniform, thereby ensuring the display effect of the liquid crystal panel and avoiding the problem of yellowing of the liquid crystal cells.

[0028] Since one end of the supporting portion is detachably connected to the circuit connection area, the supporting portion can be separated from the circuit connection area after the liquid crystal panel is subsequently cut. Therefore, it will not affect the connection between the circuit connection area and the conductive part, and there is no need to worry about affecting the bonding process quality of the circuit connection area.

DETAILED DESCRIPTION

[0038] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0039] In the present disclosure, unless otherwise specified, directional words such as “inside” and “outside” refer to the inside and outside of the corresponding structural contour.

[0040] In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0041] like Figures 1 to 5 As shown, according to one aspect of the present disclosure, a liquid crystal panel 100 is provided, wherein the liquid crystal panel 100 has at least one cell area 1, the cell area 1 includes multiple rows of cells 2, and each row of cells 2 has a spacer area 101. The liquid crystal panel 100 includes a TFT substrate 3, a CF substrate 4 and a support portion 5. The TFT substrate 3 and the CF substrate 4 are arranged opposite to each other. A circuit connection area 31 for connecting a circuit is provided on a portion of the TFT substrate 3 corresponding to the spacer area 101. One end of the support portion 5 is detachably connected to the circuit connection area 31, and the other end of the support portion 5 is connected to a first blank area 61 on the CF substrate 4 corresponding to the spacer area 101.

[0042] Wherein, cell is a liquid crystal screen that can be used for a single terminal screen. For example, each cell2 can be a liquid crystal screen of a mobile phone. A liquid crystal panel 100 has multiple cell2 units. Figure 1 and Figure 2As shown, each liquid crystal panel 100 has four cell areas 1, each cell area 1 has multiple rows of liquid crystal screen cells 2, and the multiple rows of cells 2 can be arranged at intervals along the width direction of the liquid crystal panel 100. In each row of cell 2, multiple cells 2 can be arranged along the length direction of the liquid crystal panel 100.

[0043] Liquid crystal is filled between the TFT substrate 3 and the CF substrate 4 to form a liquid crystal filling area 102. Typically, a barrier layer is provided between the TFT substrate 3 and the CF substrate 4. The barrier layer can be provided around a cell 2. The barrier layer can prevent the liquid crystal in the liquid crystal filling area 102 from contacting the outside world and can also prevent the liquid crystal in the liquid crystal filling area 102 from flowing into the spacer area 101 or the blank area and affecting the display effect. For the convenience of distinction, see Figures 2 to 5 The barrier adhesive layers at both ends of each liquid crystal filling area 102 along the width direction of the liquid crystal panel 100 are defined as a first barrier adhesive layer 11 and a second barrier adhesive layer 12 , and the barrier adhesive layers at both ends of each liquid crystal filling area 102 along the length direction of the liquid crystal panel 100 are defined as a third barrier adhesive layer 13 and a fourth barrier adhesive layer 14 .

[0044] According to the above technical solution, in the liquid crystal panel 100 provided by the present disclosure, the spacer 101 between each row of cells 2 is provided with a support portion 5, and one end of the support portion 5 is connected to the circuit connection area 31 of the TFT substrate 3, and the other end is connected to the first blank area 61 of the CF substrate 4 corresponding to the spacer 101. Therefore, the support portion 5 can provide support between the circuit connection area 31 and the first blank area 61 on the CF substrate 4. This helps to prevent the gap between the weakly supported circuit connection area 31 and the first blank area 61 on the CF substrate 4 from changing due to pressure changes when the TFT substrate 3 and the CF substrate 4 are aligned in a vacuum and then enter an air environment. Therefore, it is possible to prevent the change in the gap from affecting the gap of the adjacent liquid crystal filling area 102. In other words, the provision of the support portion 5 helps to ensure that the gap in the liquid crystal filling area 102 between the CF substrate 4 and the TFT substrate 3 remains uniform, thereby ensuring the display effect of the liquid crystal panel 100 and avoiding the problem of yellowing of the liquid crystal cells.

[0045] The circuit connection area 31 is the bonding area of the TFT substrate 3, used for connecting to a conductive member (such as an FPC flexible circuit) to achieve connection to an external circuit. In the liquid crystal panel 100 provided herein, since one end of the support portion 5 is detachably connected to the circuit connection area 31, the support portion 5 can be separated from the circuit connection area 31 after the liquid crystal panel 100 is subsequently cut. Therefore, the connection between the circuit connection area 31 and the conductive member will not be affected, and there is no need to worry about affecting the bonding process quality of the circuit connection area 31.

[0046] Since the circuit and pins are attached on the surface of the circuit connection area 31 of the TFT substrate 3 for connecting with the circuit, in order to avoid the circuit connection area 31 from being contaminated. Figure 3 and Figure 4 As shown, the support portion 5 may include a barrier coating 51 and a first supporting adhesive layer 52. One side of the barrier coating 51 is connected to the circuit connection area 31, and the other side of the barrier coating 51 is bonded to the first blank area 61 corresponding to the spacer area 101 on the CF substrate 4 through the first supporting adhesive layer 52. The adhesion of the barrier coating 51 is weaker than that of the first supporting adhesive layer 52, so that the barrier coating 51 can be peeled off from the circuit connection area 31.

[0047] A barrier coating 51 is provided on the circuit connection area 31, and a first supporting adhesive layer 52 is bonded between the first blank area 61 corresponding to the spacer area 101 on the CF substrate 4 and the barrier coating 51, thereby providing support between the CF substrate 4 and the circuit connection area 31. The barrier coating 51, located between the circuit connection area 31 and the first supporting adhesive layer 52, separates the circuit connection area 31 from the first supporting adhesive layer 52, preventing contamination of the circuit connection area 31 due to direct contact between the first supporting adhesive layer 52 and the circuit connection area 31. Furthermore, the barrier coating 51 has weaker adhesion than the first supporting adhesive layer 52, making it easier to remove during subsequent cleaning of the liquid crystal panel 100, thereby preventing residue from remaining on the circuit connection area 31.

[0048] Moreover, since the barrier coating 51 has a certain viscosity, the barrier coating 51 can be first adhered to the circuit connection area 31 to achieve pre-positioning of the barrier coating 51, ensuring that the barrier coating 51 is located on the circuit connection area 31 and blocked between the first supporting adhesive layer 52 and the circuit connection area 31. It can also avoid the position change of the barrier coating 51 affecting the position change of the first supporting adhesive layer 52 adhered to the barrier coating 51, thereby ensuring the supporting effect of the first supporting adhesive layer 52 on the circuit connection area 31 and the CF substrate 4.

[0049] After the liquid crystal panel 100 is subsequently cut, the length of the cut TFT substrate 3 can be made greater than the length of the CF substrate 4. After cutting, the length of the TFT substrate 3 longer than the CF substrate 4 can be the length of the circuit connection area 31. Figure 4As shown, since the barrier coating 51 has weaker adhesion than the first supporting adhesive layer 52, after the TFT substrate 3 and the CF substrate 4 are cut, the first supporting adhesive layer 52 will continue to adhere to the first blank area 61, that is, to the cut portion of the CF substrate 4, while the barrier coating 51 with weaker adhesion will continue to adhere to the first supporting adhesive layer 52 with stronger adhesion, and will leave the circuit connection area 31 along with the cut CF substrate 4 and the first supporting adhesive layer 52, thereby exposing the circuit connection area 31 of the TFT substrate 3 for bonding with an external circuit.

[0050] It can be understood that in other embodiments of the present disclosure, the support portion 5 may only include the above-mentioned barrier coating 51, and the barrier coating 51 is used to provide support between the circuit connection area 31 and the CF substrate 4, that is, one side of the barrier coating 51 is connected to the circuit connection area 31, and the other side of the barrier coating 51 is connected to the first blank area 61 of the CF substrate 4 corresponding to the spacer area 101.

[0051] In order to further prevent the first supporting adhesive layer 52 from contacting the circuit connection area 31, optionally, as Figure 3 As shown, the cross-sectional area of the barrier coating 51 can be larger than the cross-sectional area of the first supporting adhesive layer 52. Because the cross-sectional area of the barrier coating 51 covering the circuit connection area 31 is larger than the cross-sectional area of the first supporting adhesive layer 52 coated on the circuit connection area 31, the barrier coating 51 can better prevent the first supporting adhesive layer 52 from contacting the circuit connection area 31 and contaminating the circuit connection area 31.

[0052] To facilitate removal of the barrier coating 51, the barrier coating 51 may optionally be an organic material soluble in water or alcohol. Since the barrier coating 51 is soluble in water or alcohol, during subsequent cleaning of the liquid crystal substrate, the barrier coating 51 can be removed by rinsing the circuit connection area 31 with water or wiping the circuit connection area 31 with alcohol.

[0053] Optionally, the barrier coating 51 may be polyethylene glycol. Polyethylene glycol has good water solubility and can be removed completely with water, thereby reducing the steps and difficulty of removing the barrier coating 51.

[0054] To improve the support effect for the spacer 101, optionally, there may be multiple support portions 5, and the multiple support portions 5 may be arranged at intervals along the width direction of the spacer 101. Since there is a certain distance in the width direction of the spacer 101 between each row of cells 2, and each cell 2 corresponds to a spacer 101, multiple support portions 5 may be arranged at intervals along the width direction of each spacer 101. The multiple support portions 5 can better provide support for each spacer 101 in the width direction.

[0055] On the spacer 101, in order to ensure that the second blank area 62 of the TFT substrate 3 and the first blank area 61 of the CF substrate 4 can also be supported, optionally, as shown in FIG. Figure 2 and Figure 3 As shown, the liquid crystal panel 100 may further include a second supporting adhesive layer 7. The second supporting adhesive layer 7 may be spaced apart from the supporting portion 5 in the width direction of the spacer 101. One end of the second supporting adhesive layer 7 may be bonded to the second blank area 62 of the TFT substrate 3, and the other end of the second supporting adhesive layer 7 may be bonded to the first blank area 61 of the CF substrate 4. The second supporting adhesive layer 7 bonded between the second blank area 62 of the TFT substrate 3 and the first blank area 61 of the CF substrate 4 may provide support between the second blank area 62 of the TFT substrate 3 and the first blank area 61 of the CF substrate 4. Moreover, since the second supporting adhesive layer 7 and the supporting portion 5 are spaced apart from each other in the width direction of the spacer 101, the second supporting adhesive layer 7 may share the supporting force that the supporting portion 5 needs to bear in the width direction of the spacer 101, and may cooperate with the supporting portion 5 to jointly enhance the supporting effect in the width direction of the spacer 101.

[0056] Alternatively, as Figure 1 、 Figure 2 and Figure 5 As shown, in one embodiment of the present disclosure, the liquid crystal panel 100 may further include an encapsulation layer 8, which may be disposed around all cell regions 1 of the liquid crystal panel 100. By disposing the encapsulation layer 8 around all cell regions 1 of the liquid crystal panel 100, the CF substrate 4 and the TFT substrate 3 may be bonded together, thereby encapsulating the liquid crystal panel 100.

[0057] In order to further enhance the supporting effect of other blank areas between the CF substrate 4 and the TFT substrate 3, optionally, as Figure 2 and Figure 5 As shown, the liquid crystal panel 100 may further include a third supporting adhesive layer 9 and a fourth supporting adhesive layer 10 .

[0058] The third supporting adhesive layer 9 can be arranged around a cell area 1, and one end of the third supporting adhesive layer 9 can be bonded to the third blank area 63 of the TFT substrate 3, and the other end of the third supporting adhesive layer 9 can be bonded to the fourth blank area 64 of the CF substrate 4. By providing the third supporting adhesive layer 9 between the third blank area 63 of the TFT substrate 3 and the fourth blank area 64 of the CF substrate 4, effective support can be provided between the third blank area 63 of the TFT substrate 3 and the fourth blank area 64 of the CF substrate 4.

[0059] In the arrangement direction of each row of cells 2, that is, the length direction of the liquid crystal panel 100, the fourth supporting adhesive layer 10 can be located between the outermost cell 2 in each row of cells 2 and the third supporting adhesive layer 9, and one end of the fourth supporting adhesive layer 10 is bonded to the third blank area 63, and the other end of the fourth supporting adhesive layer 10 is bonded to the fourth blank area 64. The provision of the fourth supporting adhesive layer 10 can support multiple rows of cells 2, and the fourth supporting adhesive layer 10 located between the outermost cell 2 in each row of cells 2 and the third supporting adhesive layer 9 can also fill the blank area between the outermost cell 2 in each row of cells 2 and the third supporting adhesive layer 9, providing support for this blank area.

[0060] In order to improve the supporting effect of the fourth supporting adhesive layer 10, optionally, as Figure 5 As shown, in the arrangement direction of each row of cells 2, the distance from the fourth supporting adhesive layer 10 to the corresponding outermost cell 2 can be equal to the distance from the fourth supporting adhesive layer 10 to the third supporting adhesive layer 9. By making the distance from the fourth supporting adhesive layer 10 to the corresponding outermost cell 2 equal to the distance from the fourth supporting adhesive layer 10 to the third supporting adhesive layer 9, the fourth supporting adhesive layer 10 can provide the same supporting force between the outermost cell 2 and the third supporting adhesive layer 9, thereby improving the supporting effect of the fourth supporting adhesive layer 10.

[0061] According to another aspect of the present disclosure, a method for manufacturing a liquid crystal panel 100 is provided. The liquid crystal panel 100 has at least one cell region 1, the cell region 1 including multiple rows of cells 2, each row of cells 2 having a spacer 101 therebetween. The liquid crystal panel 100 includes a TFT substrate 3, a CF substrate 4, and a support portion 5. The TFT substrate 3 and the CF substrate 4 are disposed opposite each other. A circuit connection region 31 for connecting a circuit is provided on the portion of the TFT substrate 3 corresponding to the spacer 101. That is, the liquid crystal panel 100 may be the liquid crystal panel mentioned above. The method may include the following steps:

[0062] Before the TFT substrate 3 and the CF substrate 4 are aligned, a support portion 5 is provided on the circuit connection area 31, wherein one end of the support portion 5 can be detachably connected to the circuit connection area 31, and the other end of the support portion 5 is used to connect to the first blank area 61 on the CF substrate 4 corresponding to the spacer area 101 after the TFT substrate 3 and the CF substrate 4 are aligned.

[0063] Optionally, in the above steps, the support portion 5 may be sprayed onto the TFT substrate 3 using common spraying equipment on the market.

[0064] In the method for manufacturing a liquid crystal panel provided herein, by adding the step of providing a support portion 5 before aligning the TFT substrate 3 and the CF substrate 4, the display quality of the liquid crystal panel 100 is guaranteed, and the yellowing of the liquid crystal cells can be avoided. The support portion 5 can be peeled off from the circuit connection area 31 without affecting the connection between the circuit connection area 31 and the conductive member in subsequent processes, and there is no need to worry about affecting the bonding process quality of the circuit connection area 31.

[0065] Optionally, before aligning the TFT substrate 3 and the CF substrate 4, providing the support portion 5 on the circuit connection area 31 may include the following sub-steps:

[0066] First, a barrier coating 51 is coated on the circuit connection area 31, and then a first supporting adhesive layer 52 is coated on the barrier coating 51, wherein the end of the first supporting adhesive layer 52 away from the barrier coating 51 is used to connect with the first blank area 61 corresponding to the spacer area 101 on the CF substrate 4, and the adhesion of the barrier coating 51 is weaker than that of the first supporting adhesive layer 52, so that the barrier coating 51 can be peeled off from the circuit connection area 31.

[0067] That is, in the above steps, since the support portion 5 includes the barrier coating layer 51 and the first support adhesive layer 52 , secondary coating is adopted during coating.

[0068] After the barrier coating 51 is coated on the circuit connection area 31 , the barrier coating 51 may be cured first to form the barrier coating 51 on the circuit connection area 31 , and then the first supporting adhesive layer 52 may be coated to ensure coating quality.

[0069] Optionally, the method may further include:

[0070] Before aligning the TFT substrate 3 with the CF substrate 4, a third supporting adhesive layer 9 and a fourth supporting adhesive layer 10 are coated on one of the third blank area 63 on the TFT substrate 3 and the fourth blank area 64 on the CF substrate 4. The third supporting adhesive layer 9 is disposed around one cell area 1, and the distal end of the third supporting adhesive layer 9 is used to adhere to the other of the third blank area 63 and the fourth blank area 64 after the TFT substrate 3 and the CF substrate 4 are aligned.

[0071] In the arrangement direction of each row of cells 2, the fourth supporting adhesive layer 10 is located between the outermost cell 2 in each row of cells 2 and the third supporting adhesive layer 9, and the distal end of the fourth supporting adhesive layer 10 is used to be bonded to the other of the third blank area 63 and the fourth blank area 64 after the TFT substrate 3 and the CF substrate 4 are aligned.

[0072] Here, the distal end mentioned above and below is the end of the supporting adhesive layer that is not bonded to the substrate before the TFT substrate 3 and the CF substrate 4 are aligned. For example, if the third supporting adhesive layer 9 is coated on the TFT substrate 3, the end away from the TFT substrate 3 is the distal end; if the third supporting adhesive layer 9 is coated on the CF substrate, the end away from the CF substrate 4 is the distal end.

[0073] When coating the third supporting adhesive layer 9 and the fourth supporting adhesive layer 10 , the third supporting adhesive layer 9 and the fourth supporting adhesive layer 10 can be coated on the third blank area 63 of the TFT substrate 3 or on the fourth blank area 64 of the CF substrate 4 .

[0074] When coating the barrier coating 51 and the support adhesive layer, in order to ensure the coating quality, a gap sensor can be used to detect the distance between the nozzle and the substrate, so that the nozzle is located at a higher height where coating is required, and the distance between the nozzle and the substrate is always kept consistent during the coating process, so that a uniform barrier coating 51 or support adhesive layer can be coated.

[0075] When aligning the TFT substrate 3 and the CF substrate 4, the TFT substrate 3 and the CF substrate 4 coated with the supporting adhesive layer can be put into a vacuum device so that the TFT substrate 3 and the CF substrate 4 are aligned under vacuum conditions. The position of the TFT substrate 3 and the CF substrate 4 can be read by the alignment system so that the TFT substrate 3 and the CF substrate 4 are aligned and kept parallel before the TFT substrate 3 and the CF substrate 4 are pressed together.

[0076] Optionally, the method may further include:

[0077] Align the TFT substrate 3 and the CF substrate 4, wherein the other end of the support portion 5 is connected to the first blank area 61;

[0078] The distal end of the third supporting adhesive layer 9 is bonded to the fourth blank area 64 or the third blank area 63;

[0079] The distal end of the fourth supporting adhesive layer 10 is bonded to the fourth blank area 64 or the third blank area 63 .

[0080] After the TFT substrate 3 and the CF substrate 4 are aligned, the supporting adhesive layer can be cured by heating or UV light irradiation.

[0081] Alternatively, as Figure 4 As shown, after the liquid crystal panel 100 is cut, the support portion 5 can be peeled off from the circuit connection area 31 .

[0082] After the TFT substrate 3 and the CF substrate 4 are aligned, the aligned TFT substrate 3 and CF substrate 4 can be moved into the air, and the liquid crystal panel 100 can be cut using a high-permeability cutter wheel at a certain pressure and speed. The cut is performed at the preset positions of the CF substrate 4 and the TFT substrate 3, and the length of the TFT substrate 3 after cutting is made longer than the length of the CF substrate 4, so that the circuit connection area 31 of the TFT substrate 3 is exposed for bonding with an external circuit. After the liquid crystal panel 100 is cut, the liquid crystal screen cells can be cleaned to facilitate subsequent cell bonding. The cell surface can be cleaned by rinsing the cell with water, wiping the cell with alcohol, or rubbing the cell with a friction belt. At this time, the support portion 5 can be peeled off from the circuit connection area 31.

[0083] In the step of peeling the support portion 5 from the circuit connection area 31, plasma gas can be used to peel the support portion 5 from the surface of the circuit connection area 31. In the embodiment where the support portion 5 includes the barrier coating 51 and the first supporting adhesive layer 52, plasma gas can be used to peel the barrier coating 51 from the surface of the circuit connection area 31.

[0084] Plasma gas is a partially ionized gas, which can modify the surface of various materials, thereby removing dirt from the surface of the materials. Therefore, plasma gas can be used to peel off the support part 5 from the surface of the circuit connection area 31, thereby improving the peeling effect of the support part 5.
