Description

Touch screen sensor and touch screen with same

Technical Field

The utility model relates to a touch-sensitive screen design field particularly, relates to a touch-sensitive screen sensor and have its touch-sensitive screen.

Background

The existing touch screen with a metal grid structure is formed by manufacturing a plurality of metal electrode wires which are arranged in a crossed and parallel mode by adopting metal materials such as silver, copper, metal alloy containing silver or copper and the like so as to form a touch electrode in a metal grid shape.

At present, metal materials such as silver, copper, metal alloys containing silver or copper and the like have the characteristics of metal reflection or light opacity and the like compared with the traditional ITO electrode, so that the light transmittance of the touch screen can be reduced, and meanwhile, various light and shade stripes are formed to influence the visual sense of the screen.

The printing opacity effect is realized mainly through adopting the technical scheme that reduces the line width of metal electrode line and increase the line distance between the metal electrode line at present. However, when the line width of the metal electrode line is designed to be too narrow, the phenomenon that the touch performance is not ideal enough can occur, the difficulty of the production process is improved, the yield is reduced, and the like.

Meanwhile, most of current electronic products are produced by matching a touch screen with a display screen, and an assembly screen with a touch function and a display function is formed by laminating the touch screen and the display screen. In order to avoid the moire effect, the metal electrode wires of the touch screen need to be designed to be non-parallel to the metal electrode wires of the display screen. Because the metal electrode line among the present display screen adopts the right angle crossing design of metal electrode line square or rectangle matrix mostly, or similar structure, so the metal electrode line of metal grid structure touch-sensitive screen adopts acute angle and obtuse angle design mostly, but is the four-wire crossing form in the intersect department. Four-wire intersection is for using the crosspoint as the center, and toward having four directions outward and have an extension metal electrode line, to through the crosspoint on same straight line, the metal electrode line of two opposite directions, this department can understand two different metal electrode lines.

The metal electrode line pattern is designed on the substrate, which may be glass or a thin film material, through an etching process. In the etching process, when the etching solution is distributed in a point shape, a circular etching area is radiated by the etching tension with the etching center point as the center under the action of the surface tension. When the etching solution is distributed in a strip shape, the circular etching area can not be seen in the middle section due to the mutual covering effect of the circular etching areas, and only partial circular arc shapes of the circular etching areas can be seen at two ends.

In the prior art, as shown in fig. 1, in order to avoid the moire interference phenomenon, the intersection angle between a plurality of metal electrode lines is an acute angle and an obtuse angle, and in order to reduce the moire interference and improve the light transmittance, the line width of the metal electrode line in the prior art is generally less than 5 micrometers, so that the vicinity of the grid intersection point where the metal electrode line and the metal electrode line form the acute angle is easily etched and broken, thereby generating inferior products, and in order to show the metal electrode line etching and breaking phenomenon, the metal electrode line in the drawing is amplified.

In order to avoid the above problem, as shown in fig. 2, when it is ensured that the grid intersections are not etched and broken, the grid intersections of the metal electrode lines and the metal electrode lines are protected during the photolithography and etching processes, so that an expansion phenomenon is generated, and the problem of etching and breaking of the grid intersections of the metal electrode lines can be reduced. To illustrate the expansion phenomenon, the effect of the metal grid intersection expansion is exaggerated in the drawings. However, after the intersection points are expanded, patterns which are obviously larger than the line width of the metal electrode are formed, such as quasi-circular patterns, quasi-square patterns or quasi-diamond patterns, the length and width of the intersection point patterns or the diameter of the intersection point patterns are 7-30 micrometers, so that the intersection points and the metal electrode lines in other areas form obvious visual differences, a large number of starry signs are formed, and the visual effect is influenced.

The above background description is only for convenience to better understand the technical problems to be solved and the technical solutions to be adopted in the present application, and all the technical solutions described in the above background are not considered as prior art. I.e. some of the technical solutions mentioned in the background may also constitute specific embodiments or parts of the technical solutions of the present application.
