Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of liquid crystal screen molding, and in particular to a panel structure, a liquid crystal screen and an electronic product. Background Art
[0002] When the laptop's LCD screen is subjected to stress tests, such as dynamic pressure, static pressure or wear tests, the phenomenon of broken bright spots (also known as "starry sky") often occurs, which will seriously affect the user experience.
[0003] The padding (PS column) is arranged between the TFT substrate and the CF substrate, and is used to support the box thickness of the entire liquid crystal panel. The PS column is divided into a main column (Mian PS) and an auxiliary column (Sub PS). The main column is the column that always works under the normal working environment of the liquid crystal screen; the auxiliary column is to increase the overall supporting strength of the PS column by supporting the TFT substrate when the liquid crystal screen is accidentally subjected to external pressure, so as to prevent the display screen from being damaged by external force.
[0004] The reason for the appearance of bright spots during the pressure test is that the PS column inside the LCD screen is set on the CF substrate, and the structure on the TFT substrate that is aligned with the PS column is the alignment film (PI film); after the LCD screen is pressed, the PS column contacts the PI film. However, due to the different hardness of the PS column and the PI film, frequent contact will produce debris, which will enter the liquid crystal, thereby partially affecting the deflection of the liquid crystal, resulting in the appearance of bright spots.
[0005] The existing solution to the above problem is to reduce the height difference between the main column and the auxiliary column, increase the supporting function of the auxiliary column, and reduce the pressure of the main column to reduce the generation of debris. However, this method cannot completely eliminate the generation of debris, and the reduction of the height difference is determined according to the actual test conditions of the project. The target step difference cannot be predicted before design, and the step difference change cycle is long, which affects the project progress. Summary of the invention
[0006] In order to solve at least the above technical problems existing in the prior art, the present invention provides a panel structure, a liquid crystal screen and an electronic product.
[0007] On the one hand, the present invention provides a panel structure, including a thin film transistor substrate, a color filter substrate, a first padding structure and a second padding structure; the first padding structure is connected to the thin film transistor substrate, the second padding structure is connected to the color filter substrate, and the end of the first padding structure and the end of the second padding structure are arranged opposite to each other to form a padding structure; the first padding structure and the second padding structure have the same hardness.
[0008] In some embodiments, the first pad structure includes a first main pad and a first auxiliary pad, and the second pad structure includes a second main pad and a second auxiliary pad; the first main pad and the first auxiliary pad are staggered, the second main pad and the second auxiliary pad are staggered, and the end of the first main pad is opposite to the end of the second main pad, and the end of the first auxiliary pad is opposite to the end of the second auxiliary pad.
[0009] In some embodiments, the first main cushion has the same height as the second main cushion, and the first auxiliary cushion has the same height as the second auxiliary cushion.
[0010] In some embodiments, a black matrix film is disposed on the color filter substrate; the first pad structure and the second pad structure are located within a vertical projection range of the black matrix film toward the thin film transistor substrate.
[0011] In some embodiments, the height of the first main spacer and the second main spacer ranges from 1.1 micrometers to 1.3 micrometers; the height of the first sub-spacer and the second sub-spacer ranges from 0.9 micrometers to 1 micrometer.
[0012] In some embodiments, the first gasket structure and the second gasket structure are made of the same material.
[0013] Another aspect of the present invention provides a liquid crystal screen, comprising the above panel structure.
[0014] In yet another aspect, the present invention provides an electronic product comprising the above panel structure or the above liquid crystal screen.
[0015] The present invention provides a panel structure, a liquid crystal screen and an electronic product, wherein the panel structure includes a first pad structure and a second pad structure, and the first pad structure and the second pad structure have the same hardness. When the liquid crystal screen is subjected to external force, the first pad structure and the second pad structure are in contact with each other. When the hardness is the same, debris generated by touch can be reduced or avoided, thereby reducing or avoiding the phenomenon of bright spots on the screen.
[0016] The technical solution of the present invention can effectively solve the problem of bright spots on the screen by redesigning the form and position of the pad structure without changing the structure of other parts and without increasing the design cost of the display screen.

[0025] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0026] An embodiment of the present invention provides a panel structure, including a thin film transistor substrate, a color filter substrate, a first padding structure and a second padding structure; the thin film transistor substrate and the color filter substrate are respectively provided with a first padding structure and a second padding structure, and when the panel (liquid crystal screen) is subjected to external force, the first padding structure and the second padding structure contact each other, and the first padding structure and the second padding structure are set to have the same hardness, which can effectively avoid or reduce debris caused by contact, thereby avoiding or reducing the impact of the debris on the liquid crystal.
[0027] The following describes in detail the various structures of the panel structure provided by the embodiment of the present invention, as well as the connection relationship and position relationship of the various structures, in conjunction with the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the first padding structure 30 is connected to the thin film transistor substrate 10, the second padding structure 40 is connected to the color filter substrate 20, and the end of the first padding structure 30 and the end of the second padding structure 40 are arranged opposite to each other, thereby forming a padding structure; the hardness of the first padding structure 30 and the second padding structure 40 is the same.
[0029] Compared with the existing padding structure that is directly in contact with the alignment film, in the technical solution of the present invention, when the panel is subjected to external force, the thin film transistor substrate 10 and the color filter substrate 20 move toward each other, so that the ends of the first padding structure 30 and the second padding structure 40 will contact each other to play a supporting role. Since the hardness of the first padding structure 30 and the second padding structure 40 is the same, after contact, the occurrence of debris can be avoided or reduced.
[0030] For example, the first cushion structure 30 and the second cushion structure 40 are made of the same material, which can ensure that the first cushion structure 30 and the second cushion structure 40 have the same hardness. In the embodiment of the present invention, the specific material of the first cushion structure 30 and the second cushion structure 40 is not limited.
[0031] For example, as shown in the figure, the widths of the butt ends of the first gasket structure 30 and the second gasket structure 40 are the same. When the two are in contact, uneven force on the butt ends can be avoided or reduced, further reducing the probability of debris.
[0032] Continue to refer Figure 1 and Figure 2 As shown, the first pad structure 30 includes a first main pad 31 and a first auxiliary pad 32, and the second pad structure includes a second main pad 41 and a second auxiliary pad 42; the first main pad 31 and the first auxiliary pad 32 are staggered, the second main pad 41 and the second auxiliary pad 42 are staggered, and the end of the first main pad 31 is arranged opposite to the end of the second main pad 41, and the end of the first auxiliary pad 32 is arranged opposite to the end of the second auxiliary pad 42.
[0033] There is a height difference between the first main pad 31 and the first auxiliary pad 32, and there is a height difference between the second main pad 41 and the second auxiliary pad 42. Similar to the functions of existing pads, the first main pad 31 and the second main pad 41 are used as pillars that always support the LCD screen under normal working conditions, while the first auxiliary pad 32 and the second auxiliary pad 42 are used to cooperate with the first main pad 31 and the second main pad 41 to support the LCD screen when it is accidentally subjected to external pressure, thereby improving the supporting strength of the LCD screen.
[0034] In the embodiment of the present invention, based on the technology that the hardness of the first cushion structure 30 and the second cushion structure 40 is the same, the structures of the first cushion structure 30 and the second cushion structure 40 can be further designed to further improve the stability of the support.
[0035] Continue to refer Figure 1 and Figure 2As shown, in the embodiment of the present invention, the first main pad 31 and the second main pad 41 have the same height, and the first auxiliary pad 32 and the second auxiliary pad 42 have the same height. The pads arranged opposite to each other are symmetrical structures, and their shapes and heights are the same, so that the first main pad 31 and the second main pad 41, the first auxiliary pad 32 and the second auxiliary pad 42 have the same or similar deflection or moment, etc., further improving the stability of the pad structure.
[0036] Furthermore, in the embodiment of the present invention, the first main pad 31 and the second main pad 41, the first auxiliary pad 32 and the second auxiliary pad 42 are appropriately reduced in height compared to the existing main pads and auxiliary pads. After the height is reduced, the first main pad 31, the second main pad 41, the first auxiliary pad 32 and the second auxiliary pad 42 have smaller deflection and smaller torque when subjected to force, which can further improve the stability of the panel structure and make the structure more solid.
[0037] For example, the height range of the first main pad 31 and the second main pad 41 is ...; the height range of the first auxiliary pad 32 and the second auxiliary pad 42 is ...
[0038] Continue to refer Figure 2 As shown, in the embodiment of the present invention, a black matrix film 50 is disposed on the color filter substrate 20 ; the first pad structure 30 and the second pad structure 40 are located within the vertical projection range of the black matrix film 50 toward the TFT substrate 10 .
[0039] As shown in the figure, there is a color filter between adjacent black matrix films 50, and the positions where the first padding structure 30 and the second padding structure 40 are set need not affect the normal use of the liquid crystal 60. Therefore, the first padding structure 30 and the second padding structure 40 are both set within the vertical projection range of the black matrix film 50. The liquid crystal 60 structure will not be set within this range, thereby avoiding the situation where the first padding structure 30 and the second padding structure 40 affect the adjustment of the liquid crystal 60.
[0040] For example, in the prior art, an alignment film (PI film) is disposed on the thin film transistor substrate 10 , and the pad in the panel is in contact with the alignment film corresponding to the field effect transistor on the thin film transistor substrate 10 .
[0041] On this basis, in an embodiment of the present invention, when a pad is configured on the thin film transistor substrate 10, the pad can be set at the position of the alignment film corresponding to the film field effect transistor; that is, the second main pad 41 and the second auxiliary pad 42 can be spaced apart and set at corresponding positions.
[0042] The embodiment of the present invention further provides a liquid crystal screen, including the above panel structure, or the embodiment of the present invention further provides an electronic product, including the above panel structure or the above liquid crystal screen. The liquid crystal screen or the screen of the electronic product can avoid or reduce the appearance of broken bright spots, thereby effectively improving product quality.
[0043] The present invention provides a panel structure, a liquid crystal screen and an electronic product, wherein the panel structure includes a first padding structure 30 and a second padding structure 40, and the first padding structure 30 and the second padding structure 40 have the same hardness. When the liquid crystal screen is subjected to external force, the first padding structure 30 and the second padding structure 40 are in contact with each other. When the hardness is the same, debris generated by touch can be reduced or avoided, thereby reducing or avoiding the phenomenon of broken bright spots on the screen.
[0044] The technical solution of the present invention can effectively solve the problem of bright spots on the screen by redesigning the form and position of the pad structure without changing the structure of other parts and without increasing the design cost of the display screen.
