Touch panel to minimize signal distortion and display apparatus including the same

Abstract

Disclosed herein is a touch panel disposed on a TFT substrate 120 included in a display panel 130 to detect a touch by a touch input means 2, an entire area of the TFT substrate 120 is provided with TFT signal lines 121 including gate signal lines 121a and source signal lines 121b and is divided into a display black-matrix area DBA without pixels and a display active area DAA provided with the pixels to display an image, and the touch pads 111 and the touch signal lines 112 are patterned only at an upper position of an area corresponding to the DAA not to be vertically opposite to the TFT signal line 121.

Description

[0001] related divisional application [0002] The present invention is a divisional application of the invention patent application with the application number 201510537215.1 and the invention title "touch panel and display device including the touch panel" filed on August 27, 2015.

[0025] Therefore, in the display black matrix area DBA where the gate signal line 31a and the source signal line 31b are arranged on the TFT substrate 120, when the touch pad 11a, the touch pad 11b and the touch pad 11b of the touch panel 10 When each of the control pad 11c and the touch signal line 12a and the touch signal line 12b is vertically opposite to the TFT signal line 121 such as the gate signal line 31a and the source signal line 31b, the gate signal line 31a and the source The signal line 31b continuously turns on / off the gate electrode and the source electrode by the time sharing method, and thus as Figure 7A , Figure 7B As shown in , the electric effect of the voltage applied depending on the ON / OFF driving of the TFT signal line 31 including the gate signal line 31a and the source signal line 31b is applied to the touch pad 11a, touch pad 11b and the touch pad 11c and the touch signal line 12a and the touch signal line 12b, so that the sensed or transmitted touch signal may be coupled and distorted or may be mixed with a noise signal
