Abstract

In order to reduce the space occupied by the source circuit and the touch circuit in the touch-screen flat-panel display device, the present invention provides a touch-screen flat-panel display device. The touch panel display device includes: a display panel; a touch panel; a source circuit for receiving display signals; a touch circuit for obtaining contact coordinates; a flexible printed circuit board, wherein the source circuit is connected to The first surface of the flexible printed circuit board, the touch control circuit is connected to the second surface of the flexible printed circuit board, the first surface is fixed to the display panel, and the second surface is fixed to the touch control circuit panel. In this way, when making a module, it is only necessary to fix the lower layer of the fixed area of ​​the flexible printed circuit board to the display panel, and press the upper layer of the fixed area to the glass of the touch panel, which greatly reduces the process. save.

Description

technical field [0001] The invention relates to the technical field of flat panel display, in particular to a touch screen flat panel display device. Background technique [0002] The touch screen modes of the touch screen flat panel display device mainly include "resistive touch screen" and "capacitive touch screen". [0003] In the "resistive touch screen", two layers of conductive transparent indium tin oxide material (ITO) are set as the X electrode layer and the Y electrode layer respectively, and a "four-wire resistance" for example is arranged between the X electrode layer and the Y electrode layer. circuit structure. The Y voltage of the touch point is detected through the Y electrode layer to obtain the Y coordinate; at the same time, the X voltage of the touch point is detected through the X electrode layer to obtain the X coordinate. [0004] In the "capacitive touch screen", the horizontal electrode and the vertical electrode are made of indium tin oxide materi...
