Touch and display device having an integrated sensor controller
First Claim
1. An input device, comprising:
- a first substrate having a front surface and a rear surface, wherein the rear surface is on a side of the first substrate opposite to the front surface;
a second substrate having a first surface;
a plurality of sensor electrodes; and
a sensor controller communicatively coupled to the plurality of sensor electrodes, wherein at least a substantial portion of the sensor controller and a portion of the plurality of sensor electrodes are disposed in a volume defined by a region of overlap between the rear surface of the first substrate and the first surface of the second substrate, and wherein the sensor controller is configured to receive resulting signals from the portion of the plurality of sensor electrodes and to transmit a processed signal to a first controller.

Abstract
Embodiments of the invention generally provide an input device having a smaller overall physical size and a lower production cost, and is minimally affected by electrical interference versus conventional input devices. Embodiments discussed herein include an input device that has a sensor controller disposed in close proximity to a plurality of sensing elements that are used to sense and acquire positional information of an input object. In one embodiment, the sensor controller and at least portions of the sensor electrodes are disposed between two transparent substrates that are positioned near a display device. In some embodiments, the sensor controller is disposed in an edge region of a substrate which has a sensing region through which the adjacently positioned sensor electrodes are configured to sense the presence of an input object.
