Abstract

The invention discloses a flexible printed circuit board and a self-capacitance touch display screen. The number of independent channels in the flexible printed circuit board is smaller than the number of leads which are connected to a touch electrode, only the small number of independent channels needs to be subjected to wiring, and therefore, the problem that an existing flexible printed circuit board is over large in size is solved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a flexible circuit board and a self-capacitive touch screen. Background technique [0002] Currently, there are two types of touch screens used in the market, ie, mutual capacitive touch screens and self-capacitance touch screens. figure 1 Shown is a schematic structural diagram of a self-capacitive touch display screen in the prior art. It can be seen from the figure that the self-capacitive touch display screen 100 includes: an upper glass substrate 101 , a lower glass substrate 102 , and a liquid crystal display layer 103 . Wherein, the liquid crystal display layer 103 is distributed between the upper glass substrate 101 and the lower glass substrate 102, the common electrode 104 of the liquid crystal display layer 103 is distributed between the upper glass substrate 101 and the liquid crystal display layer 103, and the common electrode 104 is divided into A plurality ...
