Description
Technical Field
The invention relates to the technical field of display, in particular to a display panel and a preparation method thereof.
Background
With the development of display technology, various liquid crystal display devices are gradually becoming thinner and lighter, and the display quality of the panel needs to be ensured while the liquid crystal display devices are made thinner and lighter. In actual display, the panel is easy to generate broken bright spots, and the display quality of the panel is seriously influenced.
The inventors of the present application found in long-term research and development that one of the reasons why the liquid crystal display panel generates the broken bright spots is that the gap between the spacer on the color film substrate and the array substrate is too large. Specifically, in the process of preparing the liquid crystal display panel, the color film substrate provided with the spacer and the array substrate are paired, and then the next process is performed. And the gap between the spacer supports and the array substrate after the assembly is completed is about 0.2 μm (micrometer) or even higher. Because the gap between the spacing support and the array substrate is large, the spacing support cannot completely support the array substrate, and when the liquid crystal display panel is transported or touched, the array substrate and the spacing support are easy to rub to scratch the substrate, so that broken bright spots are generated, and the display quality of the liquid crystal display panel is influenced.

The preparation method of the display panel has the following beneficial effects: after the color film substrate and the array substrate which are assembled are subjected to heat treatment, the interval between the interval support and the array substrate is reduced to be within 0.1 mu m, the supporting effect of the interval support is improved, the possibility of friction between the interval support and the array substrate is reduced, the generation of broken bright spots is reduced, and the display effect of the panel is improved.
In order to solve another technical problem, the present invention provides a display panel, including a color film substrate and an array substrate, where the color film substrate is provided with a spacer; the interval between the interval support and the array substrate is less than 0.1 μm.

FIG. 2 is a schematic structural diagram of an embodiment of a display panel manufactured by the method of manufacturing a display panel according to the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1 and 2, an embodiment of a method for manufacturing a display panel according to the present invention includes:
s101, sequentially covering a black matrix 102, a color photoresist layer 103, a protective layer 104 and a spacer 105 on a substrate 101 to form a color film substrate 10;
alternatively, the black matrix 102, the color resist layer 103, the protective layer 104, and the spacer 105 may be prepared by a dyeing method, an electrodeposition method, a printing method, a pigment dispersion method, an inkjet method, or the like.
In this embodiment, the spacer includes 60-80 wt% of a solvent, 5-20 wt% of an acrylic resin, 10-20 wt% of an acrylate, 1-2 wt% of a photoinitiator, and 10-15 wt% of a binder.
S102, preparing an orientation layer 201 on the array substrate 20;
alternatively, the alignment layer 201 may be prepared by inkjet printing or the like.
S103, combining the color film substrate with the array substrate;
optionally, the color film substrate and the array substrate may be paired by a mark pair group, a glue fixing pair group, or the like.
And S104, carrying out heat treatment on the assembled color film substrate and array substrate to reduce the interval between the interval support and the array substrate to be within 0.1 mu m.
Optionally, the method for performing heat treatment on the color film substrate and the array substrate may be exposure or baking.
Optionally, during exposure, ultraviolet light is transmitted through the array substrate 20, and one end of the spacer 105 close to the array substrate 20 is exposed, so that one end of the spacer 105 close to the array substrate 20 reacts, and the other end and the side do not react. The height of the spacer 105 is increased without changing the width, which does not affect the display quality of the display panel.
Optionally, the color filter substrate 10 and the array substrate 20 are exposed as a whole, because the spacer 105 is correspondingly disposed above the black matrix 102, and a central connection line between the spacer 105 and the corresponding black matrix 102 is parallel to the light emitting direction, after the exposure or baking process, the width of the spacer 105 is less than or equal to the width of the black matrix 102, which does not affect the display quality of the display panel.
In this example, ultraviolet light is used for the exposure, the wavelength is 300nm (nanometers) to 360nm, and the energy is 5000mJ (millijoules) to 10000mJ, based on the characteristics of the spacer.
In this example, the baking temperature was 225 ℃ (degree centigrade) -235 ℃ and the baking time was 10 minutes-20 minutes, based on the characteristics of the spacer.
It will be appreciated that in other embodiments, the specific parameters of the heat treatment regime, such as exposure or baking, may be varied accordingly based on the different compositions and specific gravities of the different spacers.
In this embodiment, after the color film substrate 10 and the array substrate 20 after being assembled are subjected to heat treatment, the spacer 105 is excited by the heat treatment to initiate a reaction between the acrylic resin and the acrylate, so that the height of the spacer 105 is increased, the interval between the spacer and the alignment layer 201 is reduced, the supporting effect of the spacer 105 is improved, and the possibility of friction between the spacer and the alignment layer is reduced, thereby reducing the generation of broken bright spots and improving the display effect of the panel.
Referring to fig. 2, the display panel manufactured by the above method includes a color filter substrate 10 provided with a spacer 105 and an array substrate 20, and a distance between the spacer 105 and the array substrate 20 is less than 0.1 μm.
In this embodiment, compared with the prior art, the interval between the spacer on the color film substrate and the array substrate is significantly reduced, the structure is more stable, and the possibility of friction between the spacer and the array substrate is reduced, so that the generation of broken bright spots is reduced, and the display effect of the panel is improved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
