TOUCH SCREEN SENSOR HAVING VARYING SHEET RESISTANCE

摘要

PROBLEM TO BE SOLVED: To improve control over electrical properties of transparent touch screen sensors, without compromising optical quality or properties of a display.SOLUTION: A touch screen sensor includes a visible light transparent substrate and an electrically conductive micropattern disposed on or in the visible light transparent substrate. The micropattern includes a first region micropattern within a touch sensing area and a second region micropattern. The first region micropattern has a first sheet resistance value in a first direction, is visible light transparent, and has at least 90% open area. The second region micropattern has a second sheet resistance value in the first direction. The first sheet resistance value is different from the second sheet resistance value.SELECTED DRAWING: Figure 18
