A touch display device, its manufacturing method, and terminal equipment

Abstract

The invention relates to the technical field of display devices, and discloses a touch display device, a manufacturing method thereof, and a terminal device. The touch display device includes a touch display module, a middle frame, and a glass cover; the touch display module includes a display panel and a touch panel formed on the display panel, the touch panel is bound with a touch flexible printed circuit board, and the touch flexible printed circuit board includes a first binding part bound to the touch panel, a The second binding part, and the bending part bent along the edge of the display panel, a plurality of through holes are formed on the bending part; a module installation area is arranged on the middle frame, and the touch display module is installed on the module installation On the module installation area, a frame glue structure is formed around the module installation area, the frame glue structure is separated from the edge of the display panel by a preset safety distance, and part of it passes through the through hole; the edge of the glass cover plate is bonded to the middle frame through the frame glue structure . The touch display device effectively reduces the border, and provides a feasible technical solution for the full screen of the terminal.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a touch display device, a manufacturing method thereof, and a terminal device. Background technique [0002] At present, the AMOLED display device has been widely used in various electronic products as a display component of electronic equipment, and the AMOLED display module is an important component of the display device. Full screen has become the trend of display devices in recent years. In the application of full screen technology, a limiting factor is the lower frame. Currently, if figure 1 and figure 2 As shown, the touch sensor 02 (Touch sensor) of the AMOLED display module mainly adopts the form of an external touch panel (Touch). The flexible printed circuit board (T-FPC) 021 of the external touch panel (Touch) is separated from the flexible printed circuit board (M-FPC) 011 of the display panel 01, and the T-FPC needs to protrude from the frame of t...

Problems solved by technology

The glue on the lower frame directly avoids the T-FPC021 safety distance d 1 , so as not to cause the T-FPC to squeeze the display panel due to shrinkage of the glue, so the actual distance from the lower edge of the display module to the edge of the display panel is d 1 +d 2 , it can be seen that when the middle frame is attached to the AMOLED display module with an external touch panel, in order to ensure a sufficient safety distance, it is necessary to increase the lower border of the middle frame of the terminal product, which leads to the inability of the terminal to realize a true full-screen display.
