Description

Technical Field

[0001] The utility model relates to a liquid crystal panel, more specifically, to a liquid crystal panel component which is resistant to impurity ion penetration. Background Art

[0002] like Figure 1 As shown, one of the commonly used materials for mobile phone display screens is a liquid crystal display screen, namely a TFT-LCD, which is made of an upper glass 100 and a lower glass 200 with different functions bonded together by a frame glue 400, and the box is filled with liquid crystal 300. The display screen forms an electric field through the circuit matrix on the TFT, and then controls the rotation angle of the liquid crystal through this electric field to control the amount of light passing through to form different display images. The impurity ions in the liquid crystal box will form a self-built electric field under the action of the electric field, and this electric field will also affect the deflection of the liquid crystal.

[0003] The sources of impurity ions in the liquid crystal box are mainly impurity ions in the liquid crystal itself, PI ions and ions precipitated from the sealant 400. Among them, the impurity ions and PI ions in the liquid crystal itself exist on the entire panel and are relatively uniform. The self-built electric field of the impurity ions has the same effect on different areas of the panel. The ions precipitated from the sealant 400 (including the entry of external water vapor from the sealant 400) are mainly concentrated near the frame, such as Figure 2 As shown, the electric field generated by these ions affects the normal rotation of the surrounding liquid crystals, resulting in less light transmission around the edges of the panel, which is darker than the central area, forming a dark area S, visually creating an undesirable "frame" appearance.

[0004] Chinese invention patent document CN101285968B discloses a liquid crystal display device, which includes: a pair of substrates; an orientation film formed on each opposing surface of the pair of substrates; a sealing material formed on the outside of a display area of ​​at least one of the substrates; and a liquid crystal material encapsulated between the pair of substrates, wherein: the orientation film includes a first orientation film and a second orientation film, wherein the first orientation film is formed to at least cover the display area, and the second orientation film is formed in a region located outside the first orientation film and inside the sealing material; and the second orientation film has a higher ion impurity adsorption property than the first orientation film, wherein the second orientation film has a porous film structure.

[0005] Obviously, the patent uses an alignment film to prevent pollutants generated by the sealing material from penetrating into the display area and being fixed therein. In addition, by manufacturing a porous structure alignment film with increased film thickness, the effective surface area for adsorbing pollutants can be increased, thereby improving the efficiency of pollutant adsorption. This structure cannot solve the problem of impurity penetration in liquid crystal panels. Utility Model Content

[0006] Based on this, it is necessary to provide a liquid crystal panel assembly that prevents impurity ion penetration in order to solve the above technical problems. The liquid crystal panel assembly that prevents impurity ion penetration includes an upper glass and a lower glass. A liquid crystal layer is provided between the upper glass and the lower glass. A frame glue is provided between the upper glass and the lower glass. The frame glue surrounds the liquid crystal layer. A barrier frame is provided on the inner side of the frame glue. The barrier frame surrounds the liquid crystal layer. The inner side of the barrier frame is in close contact with the outer side of the liquid crystal layer. The outer side of the barrier frame is in close contact with the inner side of the frame glue. The barrier frame made of waterproof nano-material will not precipitate ions by itself, and has strong hydrophobic properties. After the barrier frame tightly surrounds the liquid crystal layer, it can effectively block the frame glue from precipitating ions by itself, and at the same time prevent water vapor from carrying impurity ions to penetrate into the liquid crystal layer, so that the impurity ion concentration in the peripheral area of ​​the liquid crystal panel is comparable to that in the central area, which effectively improves the uneven brightness of the center and surrounding areas of the liquid crystal panel.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The display screen forms an electric field through the circuit matrix on the TFT, and then controls the rotation angle of the liquid crystal through this electric field to control the amount of light passing through to form different display screens. The impurity ions in the liquid crystal box will form a self-built electric field under the action of the electric field, and this electric field will also affect the deflection of the liquid crystal. The sources of impurity ions in the liquid crystal box are mainly impurity ions, PI ions and precipitated ions of the frame glue 400. Among them, the impurity ions and PI ions of the liquid crystal itself exist on the entire surface of the panel, which are relatively uniform, and the influence of the self-built electric field of the impurity ions on different areas of the panel is also the same. The ions precipitated by the frame glue 400 (including the entry of external water vapor from the frame glue 400) are mainly concentrated near the frame, such as Figure 2 As shown, the electric field generated by these ions affects the normal rotation of the surrounding liquid crystals, resulting in less light transmission around the edges of the panel, which is darker than the central area, forming a dark area S, visually creating an undesirable "frame" appearance.

The frame glue 4 is in the shape of a square. The barrier frame 5 is in the shape of a square.

[0036] Through the above-mentioned structural design, the barrier frame 5 made of waterproof nano material will not precipitate ions by itself, and at the same time has strong hydrophobic properties. After the barrier frame 5 tightly surrounds the liquid crystal layer 3, it can effectively block the self-precipitation of ions by the frame glue 4, and at the same time prevent the impurity ions brought by water vapor from penetrating into the liquid crystal layer 3, so that the impurity ion concentration in the peripheral area of ​​the liquid crystal panel is equivalent to that in the central area, effectively improving the uneven brightness between the center and the surrounding areas of the liquid crystal panel.
