Abstract
A capacitive stylus and a touch control apparatus applying synchronized time difference signal transmitting method are disclosed. The capacitive styluses transmit data to a touch control apparatus via wireless communication modules respectively. A non-transitory computer-readable medium of the touch control apparatus storing instructions executable to perform a synchronized time difference signal transmitting method to synchronize time difference of the signal transmitting of the capacitive styluses.
Claims12
Capacitive styluses and a touch input apparatus applying a synchronized time difference signal transmitting method, comprising:
- at least two capacitive styluses, each of the capacitive styluses comprising a transmit electrode and a first wireless communication module;
- and
- a touch input apparatus comprising a touch panel and a time difference synchronization module, wherein the time difference synchronization module comprises an non-transitory computer readable medium and a second wireless communication module, the non-transitory computer readable medium stores executable computer readable instructions for performing the synchronized time difference signal transmitting method, comprising:
- (a) resetting parameters of the time difference synchronization module;
- (b) receiving an initiate time parameter of a first capacitive stylus by the time difference synchronization module;
- (c) setting an initiate time of the first capacitive stylus as a standard value;
- (d) receiving a time parameter of a second capacitive stylus by the time difference synchronization module;
- (e) receiving a time difference parameter from the time difference synchronization module by the second capacitive stylus;
- and
- (f) 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.
A synchronized time difference signal transmitting method, comprising:
- (a) providing a touch input apparatus comprising a touch panel and a time difference synchronization module, wherein the time difference synchronization module comprises an non-transitory computer readable medium and a first wireless communication module, the non-transitory computer readable medium stores executable computer readable instructions;
- (b) providing at least two capacitive styluses upon the touch panel, each of the capacitive styluses comprising a transmit electrode and a second wireless communication module, wherein the touch input apparatus and the capacitive styluses transmit time difference synchronization data through the first and second wireless communication modules respectively;
- (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.
