Embodiment Construction

[0017] according to figure 2 and image 3 In order to make the touch display device narrower and thinner, the embodiment of the present invention provides a touch panel 100 . The touch panel 100 includes a driving wire 101 , a sensing wire 102 , an active area 103 and an integrated circuit 104 . Both the driving wire 101 and the sensing wire 102 are metal wires. The active area 103 includes a sensor 105 , and the sensor 105 connected to the driving wire 101 and the sensor 105 connected to the sensing wire 102 are not connected to each other. The sensor 105 is connected to the driving wire 101 and the sensing wire 102 . The driving wiring 101 and the sensing wiring 102 are arranged under the sensor 105 in the active area 103, and the driving wiring 101 and the sensing wiring 102 are connected to the integrated circuit 104 and the related metal electrodes 110 through the through hole 108 in the dielectric layer 112 , and the number of driving wires 101 is greater than the n...

Abstract

A touch display device, comprising a touch panel. The touch panel comprises a metal trace, an active area, and an integrated circuit. The metal trace comprises a driving trace and an induction trace. The active area comprises a sensor. The sensor is connected to the driving trace and the induction trace. The driving trace and the induction trace are connected to the integrated circuit through a through hole in a dielectric layer, so that the touch display device achieves the effects of being light and thin and having a narrow bezel.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel in a touch display device. Background technique [0002] according to figure 1 In the conventional touch panel 10, a voltage must be applied to both ends of the metal traces (especially the driving traces) simultaneously to ensure the uniformity of the electric field in the driving direction. The metal wires are electrically connected to the integrated circuit 30 at the edge of the touch sensor 20 . The metal wires include driving wires 40 and sensing wires 50 . In addition, due to a large number of metal traces, the touch display device with the traditional touch panel 10 cannot achieve narrow frame and light weight. Contents of the invention [0003] A touch panel according to an embodiment of the present invention includes metal wiring, an active area and an integrated circuit. The active area includes the sensor, and the sensor is connected to the driving trace and...
