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 19):
A method of pressure sensing in a display device comprising:\n providing a plurality of display pixels provided above a base layer and below a cover layer of the display device; providing a plurality of pressure sensing elements above the base layer, each of the pressure sensing elements including an electrode and a pressure sensitive layer adjacent to the electrode; converting a pressure of a force applied to at least one pressure sensing element of the plurality of pressure sensing elements into a sensed force output at the electrode of the at least one pressure sensing element based on the force, wherein the sensed force output is generated by a piezoelectric effect from deformation of the pressure sensitive layer included in the at least one pressure sensing element; integrating the sensed force output of the at least one pressure sensing element using an integrator to provide an integrated value of the force sensed force output on an output of the integrator; addressing the at least one the pressure sensing elements to provide the sensed force output by turning off an addressing switch to disconnect the output of the integrator from an output of the addressing switch and cause the integrator to store a charge generated by the force sensed force output of the at least one pressure sensing element as the integrated value, and turning on the addressing switch to provide the integrated value on the output of the integrator to a the output of the addressing switch, 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, providing a current on a detection line to an input of a charge amplifier that is coupled to the output of the addressing switch and 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.
