Embodiment Construction

[0035] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0036] First of all, it should be explained that in all the embodiments of the present invention, "up" and "down" are defined according to the direction in which the backlight is emitted, and the backlight passes first as "down" and then as "up". For example, in a liquid crystal display panel, the backlight first passes through the lower polarizer, and then exits through the upper polarizer. Ex...

Abstract

The embodiment of the invention provides a flexible circuit board and a touch display device, and relates to the technical field of electronics. The problem that connection between a TSP FPC and a key FPC is poor can be solved to a certain degree. According to the scheme, the flexible circuit board comprises a touch area and a key area which are integrally formed. The touch area comprises a first circuit used for achieving touch operation of the touch display device. The key area comprises a second circuit used for achieving key pressing operation of the touch display device. The scheme is applied to the field of touch display.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a flexible circuit board and a touch display device. Background technique [0002] Touch-screen mobile phones have become the current mainstream mobile phones. It has the advantages of sensitive touch response and multi-touch support. FPC (Flexible Printed Circuit board, flexible circuit board) has high wiring density, light weight, thin thickness, and bending Because of its good foldability, it is widely used in touch screen mobile phone modules. [0003] Such as Figure 1a with Figure 1b as shown ( Figure 1a is a cross-sectional view of a touch screen mobile phone module, Figure 1b is the floor plan of the touch screen mobile phone module), the current touch screen mobile phone module contains three FPCs, which are LCD (Liquid Crystal Display, liquid crystal display) FPC02, TSP (Touch Screen Panel, Touch screen board) FPC03 and button FPC04, wherein, TSP FPC03 is boun...
