Abstract:
The present disclosure relates to a touch film, a touch panel, a touch display device and a preparing method thereof, in which breakage probability in a metal portion can be reduced, thereby improving the touch performance. The touch film comprises a flexible substrate made of polyimide, a metal layer, and an organic film arranged therebetween and having a water drop contact angle less than 80°. The touch film further comprises a touch electrode layer comprising multiple groups of first touch electrodes and multiple groups of second touch electrodes, wherein each group of the first touch electrodes comprises a plurality of first touch electrodes arrayed in a second direction; and each group of the second touch electrodes comprises a plurality of second touch electrodes arrayed in a first direction. The metal layer comprises metal connection lines for electrically connecting adjacent first touch electrodes.
