Embodiment Construction

[0033] figure 1 is a schematic top view of a touch panel according to an embodiment of the present invention, and figure 2 It is a schematic top view of a touch panel. Please refer to figure 1 , the touch panel 100 has a sensing region As and a chip contact region Ac. The wafer contact region Ac is substantially adjacent to a corner corresponding to the sensing region As. The touch panel 100 includes a plurality of first sensing bars 110 , a plurality of second sensing bars 120 , a plurality of first transmission lines 130 and a plurality of second transmission lines 140 . Both the first sensing strip 110 and the second sensing strip 120 are located in the sensing region As. Both the first transmission line 130 and the second transmission line 140 are located outside the sensing area As.

[0034] In this embodiment, each first sensing strip 110 extends along a first direction D1 and each second sensing strip 120 extends along a second direction D2, and the first directio...

Abstract

The invention provides a touch panel and a touch display unit. The touch panel is provided with a sensing area and a wafer contact area positioned on one corner of the sensing area. The touch panel comprises first sensing strips, second sensing strips, first transmission lines and second transmission lines. Each first sensing strip is positioned in the sensing area and extends along a first direction. Each second sensing strip is positioned in the sensing area and extends along a second direction. The first transmission lines and the second transmission lines are positioned outside the sensing area and respectively connected with the first sensing strips and the second sensing strips. A first pad-connecting end of each first transmission line and a second pad-connecting end of each second transmission line are positioned in the wafer contact area. The extending tracks of all the first sensing strips on the first direction do not intersect with any of the second transmission lines, and the extending tracks of all the second sensing strips on the second direction do not intersect with any of the first transmission lines.

Description

technical field [0001] The present invention relates to a touch panel and a touch display device, and in particular to a touch panel and a touch display device with a plurality of sensing bars. Background technique [0002] In recent years, all kinds of electronic products are constantly moving towards the direction of easy operation, small size and large screen size, especially portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch panel and the liquid crystal display panel, so as to omit the space required for the keyboard or the control keys, thereby expanding the configurable area of ​​the screen. [0003] Currently, touch panels can be roughly classified into resistive, capacitive, infrared and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. As far as the capacitive touch panel is concerned, the multi-touch feature pr...
