Abstract:
A pressure sensing architecture for use with liquid crystal (LC), organic light emitting diode (OLED), electrophoretic, or other similarly fabricated displays. The described architecture includes a bottom TFT structure and a top structure with color filter material, and with liquid crystal, electrophoretic or OLED material provided in between. A piezoelectric or equivalent material is provided within the display assembly. Transmitting and receiving electrodes can be used to electrically bias the piezoelectric or equivalent material, which provides an analog electrical signal in response to incident touch pressure.

Claim (Index 1):
A pressure sensing display device, cornprising:\n a cover layer; a base layer; a plurality of display pixels provided above the base layer and below the cover layer; plurality of pressure sensing elements provided above the base layer, each of the pressure sensing elements including an electrode and a pressure sensitive layer adjacent to electrode, wherein each of the pressure sensing elements is configured to convert a pressure of a force applied to the pressure sensing element into an sensed output at the electrode based on the force applied to the pressure sensing element, wherein the sensed output is generated at least in part by a piezoelectric effect from deformation of the pressure the sensitive lasyer; and, at least one detection circuit comprising: an integrator having an integrator input coupled to the electrode of at least one of the plurality of pressure sensing elements and an integrator output, wherein the integrator provides an integrated value of the sensed output of at least one of the plurality of pressure sensing elements on the integrator output; a detection line for providing a current; an addressing switch having a switch input coupled to the integrator output and a switch output coupled to the detection line, wherein the addressing switch is addressable to be switched off to disconnect the integrator output from the detection line and cause the integrator to store a charge generated by the sensed output of the at least one of the plurality of pressure sensing elements as the integrated value, and addressable to be switched on and provide the integrated value on the integrator output to the switch output, wherein the stored charge is proportional to the pressure of a force applied to the at least one of the plurality of pressure sensing elements; and, a charge amplifier having an amplifier output and, an amplifier input coupled to the switch output and to the detection line, the detection line providing the current to the charge amplifier input, wherein when the addressing switch is in the on state, the integrator output is connected to the detection line and an increase in the current at the detection line at the input of the charge amplifier caused by the integrated value causes a change in the voltage on the amplifier output indicative of the force causing the sensed output on the at least one of the plurality of pressure sensing elements.
