Abstract
A touch system may include a touch array including touch electrodes, a touch driver configured to apply touch driving signals including different codes to the touch electrodes to thereby transmit uplink signals to objects adjacent to the touch array, at least one sub-host connected to at least one object among the objects through a communication channel, and configured to receive, from the at least one object, position information corresponding to the at least one object through the communication channel, and a main host configured to receive the position information corresponding to the at least one object through the at least one sub-host.
Claims17
A touch system comprising:
- a touch array including a plurality of touch electrodes;
- a touch driver configured to apply touch driving signals including different codes respectively to the touch electrodes and to thereby transmit uplink signals to a plurality of objects adjacent to the touch array through the touch electrodes;
- at least one sub-host connected to at least one object among the plurality of objects through a communication channel, and configured to receive, from the at least one object, position information corresponding to the at least one object through the communication channel;
- and
- a main host configured to receive the position information corresponding to the at least one object among the plurality of objects through the at least one sub-host.
A display device, comprising:
- a display panel including a plurality of pixels;
- a display driver configured to drive the plurality of pixels;
- a touch array including a plurality of touch electrodes;
- a touch driver configured to apply touch driving signals including different codes to the touch electrodes to thereby transmit uplink signals to a plurality of objects adjacent to the touch array through the touch electrodes;
- at least one sub-host connected to at least one object of the plurality of objects through a communication channel, and configured to receive, from the at least one object, position information corresponding to the at least one object through the communication channel;
- and
- a main host configured to receive the position information corresponding to the at least one object among the plurality of objects through the at least one sub-host.
