Description

Technical Field

[0001] The utility model relates to the technical field of full-viewing angle display screens, in particular to a novel full-viewing angle display screen structure. Background Art

[0002] At present, most of the full-view display screens are coated with a shielding ITO layer on the top of the upper glass outside the box. The structure of the conventional full-view display is as follows: Figure 2 As shown, the built-in liquid crystal deflection electric field is inside the box, and the shielding electrode is on the upper glass. The shielding electrode will not affect the liquid crystal deflection. However, after the large glass of some mobile phone products is formed into a box, it is often thinned in different terminal applications. The thinning process will definitely remove the originally plated ITO shielding layer. In order to prevent the subsequent thinning of the glass from damaging the shielding layer and requiring re-coating, the existing technology also has the shielding layer moved inside the box for integration. As described above, if the shielding layer is moved inside the box as a whole, there will be other adverse effects. See Figure 3 The electric field changes shown mainly cause the built-in electric field used by the liquid crystal display to be destroyed. The entire shielding electrode will form an equipotential surface near the shielding electrode, resulting in the liquid crystal being unable to completely deflect in the horizontal direction, resulting in a decrease in the overall display contrast.

[0003] In order to solve the technical problems mentioned above, we have designed a new full-viewing angle display structure. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 A novel full-viewing angle display screen structure includes a TFT array substrate 2, on which an ink layer 1 is printed, the size of the ink layer 1 is adapted to the size of the array area of ​​the TFT array substrate 2, and a color ink area 1 3, a color ink area 2 4, a color ink area 3 5 and a shielding electrode 6 are arranged on the end surface of the ink layer 1.

[0024] See also Figure 1 In this embodiment, the ink layer 1 is a black conductive ink, and the ink layer 1 is connected to the ground or the display driving common electrode as a whole to form a mesh shielding layer.

[0025] Specifically, the black ink on the CF glass of the full-view display screen is made into a conductive material, namely, ink layer 1, and the conductive BM is connected to the ground or the display driving common electrode as a whole, so that the display area of ​​the entire TFT forms a mesh shielding layer to play a role in shielding interference.

[0026] See also Figure 1 In this embodiment, the color ink area 1 3 is provided with two columns, and each column includes three color ink areas 1 3, and the two columns of color ink areas 1 3 are respectively printed on the left and right sides of the end surface of the ink layer 1, the color ink area 2 4 is provided with one column, and each column includes three color ink areas 2 4, and one column of color ink areas 2 4 is printed between the two columns of color ink areas 1 3 of the ink layer 1 and close to the right side, the color ink area 3 5 is provided with one column, and each column includes three color ink areas 3 5, and one column of color ink areas 3 5 is printed between the two columns of color ink areas 1 3 of the ink layer 1 and close to the left side, the color ink area 1 3 is red ink, the color ink area 2 4 is green ink, and the color ink area 3 5 is blue ink.

[0027] Specifically, the color ink area 1 3, the color ink area 2 4 and the color ink area 3 5 can form an RGB color area, so that the TFT display is mainly a liquid crystal deflection display of the RGB color area. There are gaps between the three color inks in the color ink area 1 3, the color ink area 2 4 and the color ink area 3 5, and they are separated, which can ensure that there is a black ink area in the ink layer 1 that is not mixed and does not leak light.

[0028] See also Figure 1 In this embodiment, gaps of equal distance are arranged between the color ink area 1 3 , the color ink area 2 4 and the color ink area 3 5 , and staggered shielding electrodes 6 are arranged in the gaps.

[0029] Specifically, the shielding electrode 6 can replace the original ITO shielding and play a better shielding role.

[0030] See also Figure 1 In this embodiment, the color ink area 1 3 , the color ink area 2 4 , and the color ink area 3 5 are all the same in size and thickness.

[0031] Specifically, the color ink area 1 3 , the color ink area 2 4 , and the color ink area 3 5 are all the same in size and thickness, thereby ensuring the flatness of the ink layer 1 , which is beneficial to display.

[0032] It should be noted that the ink layer 1 is printed on the upper CF glass of the TFT display screen, and the three color inks on the ink layer 1 are separated to ensure a black ink area without color mixing and light leakage. The black ink on the CF glass of the full-view display screen is made of a conductive material, and the conductive BM is connected to the ground or the display driving common electrode as a whole, so that the display area of ​​the entire TFT forms a mesh shielding layer to play a role in shielding interference.
