Title:
FLEXIBLE PRINTED CIRCUIT AND TOUCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/068463
Kind Code:
A1
Abstract:
Disclosed are a flexible printed circuit and a touch device. The flexible printed circuit (3) comprises a light guiding area (5) arranged on a base material, that has pre-set transparency, of the flexible printed circuit (3), and a key area (6) arranged around the light guiding area (5), wherein a light equalization film is silk-printed in the light guiding area (5), and touch keys are arranged in the key area (6). The touch device comprises the flexible printed circuit (3), and a touch panel (4) stacked on the flexible printed circuit (3), wherein touch areas (8) are arranged on the touch panel (4); and the touch areas (8) on the touch panel (4) correspond to the positions of the touch keys on the flexible printed circuit (3). Since neither light guiding films nor light guiding pillars are arranged on the touch device, a saved space between a liquid crystal display and the touch panel is used to arrange a thicker light equalization film on the flexible printed circuit, so that the flexible printed circuit has functions of light guiding and light equalization, thus improving light guiding and light equalization effects.
