Abstract

A touch display apparatus is disclosed. The touch display apparatus includes a touch display panel, a chip on film (COF) layer and a driving circuit. The touch display panel includes a display moduleand a touch sensor. The touch sensor is disposed on the display module. The COF layer includes a connecting portion and an extending portion connected to each other. The connecting portion is coupledto the display module, and the extending portion is coupled to the touch sensor. The driving circuit is disposed on the COF layer. The driving circuit transmits touch signals with the touch sensor through the COF layer and its extending portion.

Description

technical field [0001] The present invention relates to a display device, in particular to a touch display device. Background technique [0002] In the prior art, when an On-Cell touch display panel applied to a wearable touch display device is combined with a Touch and Display Driver (Touch and Display Driver) packaged in a Chip On Film (COF) package, Integration, TDDI) integrated circuit, because the touch sensor (Touch Sensor) contact of the On-Cell touch display panel is located on the upper glass, and the touch and display driver integration (TDDI ) The bonding position of the integrated circuit is located on the bottom glass of the display module. Therefore, the two need to be additionally coupled through a flexible printed circuit board (Flexible Printed Circuit, FPC) for touch control, so that the touch and display The driver integration (TDDI) integrated circuit and the touch sensor can transmit touch signals and can be connected to the Sensor. [0003] At present...
