| 发明名称 | Passive architecture and control method for scanning a touch panel | ||
| 摘要 | A passive architecture for scanning a touch panel includes a master IC and at least one passive touch IC connected to the master IC. The master IC generates a command to configure the scan parameters of the at least one passive touch IC, and the at least one passive touch IC scans the touch panel with the scan parameters in response to the command. | ||

| 主权项 | 1. A passive architecture for scanning a touch panel, comprising: at least two first ICs connected to the touch panel; and a second IC for providing each of the at least two first ICs with a corresponding scan parameter; wherein each of the at least two first ICs simultaneously scans the touch panel according to its corresponding scan parameter; wherein the corresponding scan parameter which the second IC provides for each of the at least two first ICs comprises different trace combinations in a first direction to be scanned; and wherein the corresponding scan parameter enables a corresponding one of the at least two first ICs to scan specified traces, the number of which is less than the total number of traces in the first direction of the touch panel. | ||
