Abstract
A synchronized time difference signal transmitting method and capacitive styluses as well as a touch input apparatus applying this method are disclosed. The touch input apparatus uses a time difference synchronization module and the capacitive styluses use synchronization interfaces to synchronize time difference of the signal transmitting of the capacitive styluses.
Claims10
A synchronized time difference signal transmitting method, comprising:
- (a) providing a touch input apparatus comprising a touch panel and a time difference synchronization module;
- (b) providing at least two capacitive styluses upon the touch panel, each of the capacitive styluses comprising a synchronization interface and a transmit electrode, wherein the time difference synchronization module connects to each synchronization interface to transmit time difference synchronization data;
- (c) resetting parameters of the time difference synchronization module;
- (d) receiving an initiate time parameter of a first capacitive stylus by the time difference synchronization module;
- (e) setting an initiate time of the first capacitive stylus as a standard value;
- (f) receiving a time parameter of a second capacitive stylus by the time difference synchronization module;
- (g) receiving a time difference parameter from the time difference synchronization module by the second capacitive stylus;
- and
- (h) adjusting an initiate time parameter of the second capacitive stylus such that the difference between the initiate time parameters of the first and second capacitive styluses is the time difference parameter.
