Problems solved by technology

On the inner side of the protective substrate, it is generally necessary to set a frame of a layer of light-shielding material (such as black ink) to block the peripheral area of ​​the touch-sensitive circuit layer and the display, mainly to block the peripheral lines on the peripheral area. However, the existence of the frame Tend to make the display area of ​​the display appear smaller and affect the appearance of handheld electronic devices (such as mobile phones) that use such touch screens

Embodiment 1

[0032] like figure 1 As shown, the manufacturing method of the touch screen protective substrate realizing the ultra-narrow frame includes the following steps:

[0033] (1), establish a plurality of different 3D models, each 3D model includes a simulated background color layer 1 and a simulated transparent substrate 3 having a refractive index and thickness arranged on the simulated background color layer 1, and the simulated background color layer 1 is provided with The edge black frame 4 simulates that the transparent substrate 3 has an edge chamfer 5, and the edge chamfer 5 corresponds to the position of the edge black frame 4; each 3D model is the same except that the edge chamfer 5 is inconsistent; then make each The edge chamfer 5 in the 3D model changes gradually, and then slices 6 with the edge chamfer 5 are cut from each 3D model, and each slice 6 with the edge chamfer 5 is superimposed on the Together form a laminated 3D model 7, the edge chamfer 5 adopts a positive...

Embodiment 2

[0039] Under the situation that other parts are all identical with embodiment one, its difference is: as image 3 As shown, in step (1), the edge chamfer 5 of each slice 6 is an elliptical arc chamfer, and the ratio of the longitudinal axis to the transverse axis of the ellipse gradually changes according to the order of the overlapping of each slice 6, wherein the semi-short axis of the ellipse is 1.7mm, the semi-major axis > 1.7mm, the elliptical arc gradually changes; in step (2), the widest part C of the screen overflows is the best narrow frame effect, and the semi-major axis of the ellipse arc corresponding to the best point is 2.3mm, semi-short The axis is 1.7mm, and the corresponding optimal ellipse arc chamfer is as follows Figure 4as shown in D; Figure 5 As shown, in step (3), select the slice 6 corresponding to the position E where the narrow border effect is the best, and rebuild the optimal 3D model according to the edge chamfer 5 of the slice 6 .

Embodiment 3

[0041] In the case that other parts are the same as in the second embodiment, the difference is that the thickness of the simulated transparent substrate 3 is reduced to 1.0 mm, and the semi-minor axis is 0.7 mm.

[0042] like Image 6 , Figure 7 , Figure 8 As shown by F, G, and H in the figure, as the semi-major axis of the ellipse arc increases, the overflowing part F of the picture first increases and then decreases. The semi-major axis of G is 2.7mm, the semi-minor axis is 0.7mm, and the part F of the screen overflows is less, and the overall effect is not obvious.

Abstract

The invention relates to a manufacturing method for a touch screen protection base plate with an ultra-narrow edge frame. The manufacturing method comprises the following steps: (1) a plurality of different 3D models are established, wherein each 3D model comprises a simulated bottom color layer and a simulated transparent base plate which is arranged on the simulated bottom color layer and has refractive index and thickness; the simulated bottom color layer is provided with an edge black frame and the simulated transparent base plate is provided with an edge chamfer; the edge chamfers of all the 3D models are different; (2) a computer is used for simulating; all the 3D models are observed above the 3D models by the same visual angle; (3) the optimal 3D model with the optimal narrow edge effect is selected; (4) one transparent base plate is adopted and the edge of the transparent base plate is machined into the edge the same as that of the optimal 3D model. By the aid of the manufacturing method, the better touch screen protection base plate with the ultra-narrow edge frame can be manufactured so that the edge frame of a touch screen looks narrower and a lot of testing work is saved; the system analysis is convenient to carry out and a rule is convenient to conclude, so that the touch screen has the best narrow edge frame effect.

Description

technical field [0001] The invention relates to a manufacturing method of a touch screen substrate, in particular to a manufacturing method of a touch screen protective substrate realizing an ultra-narrow frame. Background technique [0002] Capacitive touch screens generally include a layer of touch-sensing circuit layer (hereinafter referred to as "touch-sensing circuit layer") designed based on the principle of capacitive sensing. This circuit layer generally includes a transparent area and a surrounding area. The transparent area is generally provided with transparent sensing electrodes. The surrounding area Generally, peripheral circuits are provided. When the capacitive touch screen and a display form a touch display component, the transparent area and the peripheral area of ​​the touch screen correspond to the display area and the peripheral area of ​​the display respectively. Thus, the transparent area of ​​the touch screen can pass through the display area. The emit...
