Abstract

The invention provides a touch display device. The touch display device comprises a display module, a flexible printed circuit board, a touch module and a colloid layer, wherein the display module contains a display surface, the flexible printed circuit board is connected with the edge of the display surface, the touch module contains a faying surface arranged opposite to the display surface, the faying surface and the display surface are fit, an interval is formed between the touch module and the flexible printed circuit board, and the colloid layer fills the interval to fix the flexible printed circuit board to the faying surface of a touch panel. The flexible printed circuit board is fixed to the touch module through the colloid layer, so that the touch display device eliminates the stress generated when the flexible printed circuit board is bent, and solves the problems that the display module deforms due to the stress and further display brightness is uneven. The invention further provides a manufacturing method of the touch display device.

Description

technical field [0001] The invention relates to a touch technology, in particular to a touch display device and a manufacturing method thereof. Background technique [0002] In recent years, a touch display device has been widely used as an inductive display device capable of receiving a touch operation to generate an input signal. [0003] Generally speaking, a touch display device mainly includes a touch module and a display module. The display module includes a display surface and a non-display surface opposite to the display surface. A flexible printed circuit board is connected to an edge of the display surface. When bonding the touch module and the display module, reserve a certain space between the touch module and the display module to accommodate the flexible printed circuit board and ensure that the flexible printed circuit board is not squeezed. Generally, the flexible printed circuit board is movable in the reserved space. After the touch module and the display...
