This application proposes a display panel 100.

1, the display panel 100 proposed by the technical solution of the present application includes:

It includes a first substrate 10, a second substrate 30, a liquid crystal layer filled between the first substrate 10 and the second substrate 30, and a frame sealant 50. The display panel 100 includes an effective display area 20 and a surround In the non-display area 40 of the effective display area 20, a main spacer 90 is provided in the effective display area 20, one end of the main spacer 90 abuts the second substrate 30, and the other end abuts The first substrate 10 defines the extension height of the main spacer 90 from the first substrate 10 to the second substrate 30 as h ₁ ;

The display panel 100 further includes a transition spacer 70 disposed in the non-display area 40, one end of the transition spacer 70 forms a gap with the second substrate 30, and the other end abuts the first The substrate 10 defines that the transition spacer 70 extends from the first substrate 10 to the second substrate 30 to a height h ₂ ;

The h ₁ -h ₂ &lt; 0.3 μm.

In the technical solution of the present application, the transition spacer 70 is provided in the non-display area 40, and the height of the transition spacer 70 is at least 0.3 μm lower than the height of the main spacer 90 located in the effective display area 20, so that the non-display area 40 When a greater force is applied than the effective display area 20, the transition spacer 70 may support the deformed second substrate 30 or the first substrate 10, thereby canceling the force, so that the main spacer 90 When compressed, its deformation reaches the height of the transition spacer 70, ensuring that the box thickness of the effective display area 20 and the non-display area 20 is the same, and because the height difference between the main spacer 90 and the transition spacer 70 is defined If it is less than 0.3 μm, the compressed amount of the display panel 100 is within a small deformation range, and then the entire display panel 100 can maintain a uniform thickness even when pressed and pressed, and the peripheral chromatic aberration is small.

1 and 2, in an embodiment of the present application, the main spacer 90 is located between the first substrate 10 and the second substrate 30 to support the first substrate 10 and the second substrate 30. The provision of the main spacer 90 can play a uniform role on the liquid crystal layer flowing between the first substrate 10 and the second substrate 30, and can ensure the filling amount of the liquid crystal and prevent the adverse effect of the liquid crystal dripping amount error on the product.

In addition, a sub-separator 80 for providing pressure resistance is provided between the first substrate 10 and the second substrate 30, and the sub-separator 80 is defined from the first substrate 10 to the second substrate 30. extending a height h _3, that h ₃ is less than h ₁ and h _2, when the effective display region 20 is compressed, primary spacers 90 are first compressed, followed by 70 is compressed as the transition spacer, and finally the secondary spacer Object 80 is compressed. In this embodiment, the step difference between the primary spacer 90 and the secondary spacer 80 is 0.15 μm to 0.55 μm. Since the area of the effective display area 20 is generally larger than that of the non-display area 20, the level difference between the main spacer 90 and the sub-spacer 80 can be large. When the breakage h is less than 0.15 μm, the fluctuation of the liquid crystal will be reduced. As a result, the display effect of the display panel 100 is affected. When the cut-off h is greater than 0.55 μm, although the liquid crystal fluctuation amount will increase, it will always cause the main spacer 90 to play a supporting role, and the sub-spacer 80 does not easily play a supporting role The pressure resistance of the display device is greatly reduced, causing poor display. When the value of the cut-off h is between 0.15 μm and 0.55 μm, the effective display area 20 of the display panel 100 can have a good pressure resistance, and can satisfy a better liquid crystal fluctuation amount, and its comprehensiveness is better. Specifically, the break h may be 0.2 μm, 0.3 μm, 0.4 μm, 0.45 μm, 0.5 μm, etc., all of which enable the display panel 100 to have a better display effect.

The process of the main spacer 90 can use a gray tone (Gray Tone) mask or halftone (Half Tone) The reticle combines different exposure levels to control the position and thickness of the main spacer 90. If the step difference between the main spacers 90 is increased by changing the thickness of the main spacers 90, a different Gray needs to be replaced Tone mask or Half Tone mask, and the price of the Gray Tone mask or Half Tone mask is relatively high, which will increase the manufacturing cost of the display panel 100.

In an embodiment of the present application, the 0.15 μm ≦ h ₁ -h ₂ ≦ 0.25 μm. The compressed amount of the display panel 100 is within a small deformation range, and then the entire display panel 100 can maintain a uniform thickness even when pressed and pressed, and eliminate peripheral chromatic aberration.

In another embodiment of the present application, the non-display area 40 includes a first peripheral area 41 and a second peripheral area 43, the first peripheral area 41 is disposed adjacent to the effective display area 20, and the second periphery The area 43 is disposed away from the effective display area 20, and the frame sealant 50 is located between the first peripheral area 41 and the second peripheral area 43;

The transition spacer 70 is located in the first peripheral area 41;

And / or, the transition spacer 70 is located in the second peripheral area 43. A transition spacer 70 may be provided in both the first peripheral area 41 and the second peripheral area 43, so that when the display panel 100 is cut, the transition spacer 70 located in the first peripheral area 41 and the second peripheral area 43 Both can limit the deformation of the display panel 110, and the spacers located in the effective display area 20 can provide auxiliary support to further reduce the defect rate of the display panel 100.

Referring to FIG. 2, in an embodiment of the present application, the number of the transition spacers 70 is plural, and the plurality of transition spacers 70 are evenly arranged in the non-display area 40 at intervals; and / or, ;

And / or, the main spacer 90 includes a first body portion 91 and a first support block 93 fixedly connected to the first body portion 91, the first support block 93 is provided in the effective display area 20 Inside;

And / or, the transition spacer 70 includes a second body portion 74 and a second support block 75 fixedly connected to the second body portion 74, the second support block 75 is provided in the non-display area 40 Inside. Providing a plurality of spaced-apart transition spacers 70 in the non-display area 40 can keep the cell thickness when the non-display area 40 receives a large pressure, so as not to affect the liquid crystal in the effective display area 20 normal work. Moreover, since the non-display area 40 does not participate in the screen transmission of the display panel 100, more transition spacers 70 can be provided in the non-display area 40, which greatly improves the compression support effect of the non-display area 40, thereby facilitating the use . It can be understood that the transition spacer 70 may be arranged in a longitudinal direction, a lateral direction, or an oblique direction, as long as it is convenient for support. A support block is provided to facilitate the transition spacer 70 to support the non-display area 40. In this embodiment, the first support block 93 is a third color layer. In this way, the material of the spacer is saved, thereby facilitating cost saving.

In an embodiment of the present application, the transition spacer 70 is arranged in a column shape; setting the transition spacer 70 in a column shape can make the transition spacer 70 have a higher elastic recovery rate and an ability to withstand external pressure deformation; It will not cause pollution to the liquid crystal; and the columnar transition spacer 70 is convenient for controlling its density, making the film thickness uniformity better;

Alternatively, the transition spacer 70 is provided in a spherical shape; setting the transition spacer 70 in a column shape can make the transition spacer 70 reduce scratches caused by the friction of the color film during vibration, and it has a high elastic recovery Rate and external pressure deformation tolerance, easy to support the non-display area 40;

Alternatively, the transition spacer 70 is provided in a block shape. The large supporting surface of the transition spacer 70 provided in a block shape is convenient for realizing that the supporting area of the transition spacer 70 and the unit pixel area are relatively large, thereby improving the supporting effect of the transition spacer 70.

In an embodiment of the present application, the number of the main spacers 90 is less than the number of the transition spacers 70. Specifically, the density value is defined as the ratio of the area of the top support surface of the spacer to the area of the smallest repeated unit pixel. The density value of the main spacer 90 is less than the density value of the transition spacer 70. The support effect in 40 is better. Even in the case of high external pressure, the number of transition spacers 70 is large, so the deformation amount of the non-display area 40 is small, thereby ensuring that the liquid crystal in the effective display area 20 is not Will be affected. It can be understood that the density of the transition spacer 70 can be increased by increasing the area of the top supporting surface of the transition spacer 70 or increasing the number of transition spacers 70.

In an embodiment of the present application, the height of the transition spacer 70 is the same; setting the transition spacer 70 with the same height is convenient for production and installation, and does not need to calculate its arrangement, as long as it is evenly arranged It has better support performance, so that the deformation amount of the non-display area 20 when subjected to external pressure is small;

Alternatively, the transition spacer 70 includes a first transition spacer 71 and a second transition spacer 72, and the height of the first transition spacer 71 is higher than the height of the second transition spacer 72 . The first transition spacer 71 and the second transition spacer 72 with different heights can be supported by the different elastic supporting forces when the display panel 100 is under pressure, and the first transition spacer 71 when receiving less pressure The box thickness of the display panel 100 is controlled. When a large pressure is applied, the first transition spacer 71 and the second transition spacer 72 both control the box thickness of the display panel 100. When the liquid crystal is large, the fluctuation amount of the liquid crystal will be increased, thereby improving the display effect. Therefore, using the first transition spacer 71 and the second transition spacer 72 with different heights can ensure the box thickness of the display panel 100 and make the display effect better . It can be understood that the auxiliary spacer may further include a third transition spacer 73 whose height is between the first transition spacer 71 and the second transition spacer 72, so that the transition spacer 70 faces the non-display area 40's support effect is better.

Further, in an embodiment of the present application, the first transition spacer 71 may be disposed close to the frame sealant 50, so as to facilitate the display panel 100 to be subjected to pressure surrounding the frame sealant 50 When the panel is cut), the first transition spacer 71 supports the outer edge of the non-display area 40, which can effectively prevent the box thickness of the display panel 100 from being affected.

Further, in an embodiment of the present application, the first transition spacer 71 and the second transition spacer 72 may be alternately arranged in the non-display area 40, such arrangement can make the first transition spacer 71 and The second transition spacer 72 uniformly supports the non-display area 40, and can support the display panel 100 evenly when the non-display area 40 is subjected to external pressure, effectively preventing the box thickness of the display panel 100 from being affected.

Further, in the case where the transition spacer 70 is subjected to external force to achieve equilibrium through compression, The acting force of the transition spacer 70 and the compression amount of the transition spacer 70, the density of the transition spacer 70 (that is, the total area occupied by the transition spacer 70 per unit area) and the transition spacer 70 The relationship between the force experienced by compressing a unit volume (μm3) is:

F = a × b × c

Among them: F is the force on the transition spacer 70, mN;

a is the compression amount of the transition spacer 70, μm;

b is the density of the transition spacer 70, μm ² / mm ² ;

c is the force that the transition spacer 70 receives per unit volume (μm3) compressed, mN.

Since the force that the transition spacer 70 is compressed per unit volume (μm3) is related to the material of the transition spacer 70, when the external force received by the display panel 100 and the material of the transition spacer 70 are constant To ensure the same amount of compression in the two areas, it is necessary to ensure that the spacers in the two areas bear the same force, and the additional force (that is, the force received by the non-display area 40 is the same as the effective display area 20. The difference between the applied forces) needs to be borne by the transition spacer 70. In this embodiment, the density of the transition spacer 70 located in the non-display area 40 is equal to the density of the main spacer 90 located in the effective display area 20, thereby ensuring the same amount of compression in both areas.

In an embodiment of the present application, the height h ₁ of the main spacer 90 is 2.8 μm, so that the height h _{2 of the} transition spacer 70 may be 2.5 μm <h ₂ <2.8 μm. Specifically, the value of h ₂ is The values can be 2.55 μm, 2.6 μm, 2.65 μm, 2.7 μm, 2.75 μm, etc., all of which can achieve a better supporting effect. The density of the transition spacer 70 may be 1800 μm ² / mm ² or 2200 μm ² / mm ² or 2400 μm ² / mm ^{2. In} this way, the non-display area 40 can be better supported when subjected to an external force.

In an embodiment of the present application, the spacer includes a spacer body and a metal piece on top of the spacer body. In this embodiment, all the spacers can be configured to include the structure of the spacer body and the metal layer, so as to maximize the support strength of the spacer. For a display device in which a spacer includes a main spacer 90 and a transition spacer 70, a main body of the main spacer 90 and a transition spacer 70 with different heights may be formed by a half-tone mask process first, and then patterned The process forms a metal layer at the top of the main body of the main spacer 90 and the top of the body of the transition spacer 70 at once.

Alternatively, all the transition spacers 70 may be designed to include a structure of the transition spacer 70 body and a metal layer. The cushion is an integrated structure to increase the supporting strength of the transition spacer 70. For the septum includes the main septum 90 and the sub For a display device of a spacer, a main body of a main spacer 90 and a sub-spacer 80 having different heights may be formed by a halftone mask process, and then a metal layer may be formed on top of the main body of the transition spacer 70 by a patterning process.

Alternatively, all the primary spacers 90 may be designed to include a structure of the main spacer 90 main body and the metal layer, and the secondary spacer 80 is an integral structure to increase the supporting strength of the primary spacer 90. For a display device in which the spacer includes the main spacer 90 and the transition spacer 70, the main body of the main spacer 90 and the transition spacer 70 with different heights may be formed first using a halftone mask process, and then the patterning process may be used A metal layer is formed on the top of the main body of the main spacer 90.

In this embodiment, the main body of the spacer may use low hardness polyurethane resin or low hardness polypropylene resin, etc. Made of resin with lower hardness; metal layer can be made of materials with higher hardness, such as: Mo (molybdenum), Al (aluminum), ITO (indium tin oxide) and other materials, the thickness of the metal layer is preferably 0.2 μm ～ 0.5μm Between. It can be understood that when the metal layer is provided, the height of the main body of the spacer is reduced, so that the step difference between the main spacer 90 and the transition spacer 70 remains within 0.3 μm.

In an embodiment of the present application, a transition spacer 70 may also be provided on the outside of the frame sealant 50, and the transition spacer 70 provided on the outside of the frame sealant 50 may be the first transition spacer with a relatively high height 71 and the second transition spacer 72 with a low height, such a setting can further improve the support effect on the non-display area 40.
