Touch display device and aligning method thereof

Abstract

A touch display device includes a first substrate, a second substrate, a touch electrode layer and a flexible printed circuit board, wherein the first substrate is provided with a first aligning pattern; the second substrate is opposite to the first substrate, and is provided with a shading area; the touch electrode layer is arranged on the second substrate, is in contact with the second substrate, and is provided with a second aligning pattern; the second aligning pattern is arranged on the shading area; the flexible printed circuit board is arranged on the touch electrode layer, and is provided with a third aligning pattern and a fourth aligning pattern; the third aligning pattern is arranged on the second aligning pattern; the fourth aligning pattern is not superposed with the second substrate and the touch electrode layer, and is spaced from the second substrate and the touch electrode layer at an interval of 0-5 mm; alignment is achieved when the flexible printed circuit board is connected with the touch electrode layer.

Description

technical field [0001] The present invention relates to a technology of a touch display device, in particular to a touch display device suitable for a transmissive image sensor. Background technique [0002] With the advancement of technology, touch modules tend to be gradually integrated into personal mobile devices, such as personal digital assistants (personal digital assistants, PDAs), smart phones (Smart Phones), and satellite navigation devices. It is convenient to operate by controlling the screen of this mobile device. [0003] figure 1 It is a cross-sectional schematic diagram of a conventional packaging alignment device for a touch display panel. The conventional package alignment device 10 includes a thin film transistor array (Thin Film Transistor Array, TFT Array) 110, a color filter (Color Filter, CF) 120, a touch electrode layer (Touch Electrode Layer) 130 and a flexible Circuit board (Flexible Printed Circuit, FPC) 140 . The color filter 120 is disposed o...
