Methods and systems are disclosed for reducing signal interference between Bluetooth (BT) and WLAN (e.g. WiFi) communications in an information handling system. The WLAN receiver has configurable front-end filter circuitry. Based upon information concerning the BT frequency region for current BT communications, the WLAN receiver can adjust or set its configurable front-end filter circuitry to filter out the BT communications. As the BT communications hop from frequency to frequency, the WLAN receiver can continue to adjust its configurable front-end filter circuitry accordingly. Example implementations for the configurable front-end filter circuitry include bandpass filters and selectable low pass and high pass filters. These filters are selected and/or tuned such that BT frequency regions are filtered from the WLAN input signal before further WLAN signal processing is conducted, thereby improving the performance of simultaneous BT and WLAN communications.

Errors in touch detection algorithms may be reduced by providing a more uniform spacing between successive sense elements. In some embodiments, one or more dummy ground elements may be inserted between adjacent sense elements in order to reduce signal interference.

The present invention divides a wire supplying a scan start signal to a gate driver into two wires, so as to avoid overlapping a clock signal line. In this way the clock signal is not delayed by interference, and a gate driving margin may continue uninterrupted, thereby uniformly outputting a gate-on voltage. In particular, if the clock signal line is connected to all stages in the gate driver and the clock signal line overlaps the scan start signal line, unsightly horizontal bands appear on the image and the parallel gate lines generate a very large parasitic capacitance. In contrast, the gate drivers in the present disclosure comprise clock signal lines which do not overlap the scan start signal lines. As benefits, interference resulting in horizontal banding is minimized and the power consumption may be reduced by about 10%.
