Abstract:
1. A touch panel display device, comprising: a display panel having a scroll bar extending along a Y-axis direction; a lower transparent sheet bonded to the display panel; an upper transparent sheet over the lower transparent sheet and separated from the lower transparent sheet; an upper conductive transparent film formed on the upper transparent sheet and having only a pair of first electrodes extending only along a X-axis direction that perpendicularly crosses the Y-axis direction of the scroll bar with no electrodes extending along the Y-axis, wherein each of the first electrodes has a shape with two longer opposing sides and two shorter sides; a lower conductive transparent film formed on the lower transparent sheet and having only a pair of substantially opposing second electrodes extending only along the Y-axis direction, wherein the lower conductive transparent film is disposed between the display panel and the upper conductive transparent film, wherein each of the second electrodes has a shape with two longer opposing sides and two shorter sides; a first tail line directly connected to one of the two shorter sides of one of the first electrodes; a second tail line directly connected to one of the two shorter sides of the other one of the first electrodes; a third tail line directly connected to one of the two shorter sides of one of the second electrodes; and a fourth tail line directly connected to one of the two shorter sides of the other one of the second electrodes, wherein the second electrodes and the first through the fourth tail lines are concentrated along a plurality of edges of the touch panel so as not to form a dead space margin along an edge of the touch panel extending in the Y-axis.
