Electronic device with touch sensitive display
First Claim
1. An electronic device that receives touch input from an external object, comprising:
- a housing; and
a touch screen display in the housing, wherein the touch screen display has a two-dimensional touch sensor that determines a touch contact point between the external object and the touch screen display, wherein the two-dimensional touch sensor has a first position sensor that determines a first position of the touch contact point along a first axis and a second position sensor that determines a second position of the touch contact point along a second axis, wherein the first axis is perpendicular to the second axis, wherein the first position sensor comprises a capacitive touch sensor comprising capacitive electrodes that extend along the second axis, wherein the second position sensor is a non-capacitive touch sensor comprising conductive structures that extend along the first axis, and wherein the capacitive electrodes and the conductive structures do not overlap.

Abstract
An electronic device may be provided with a touch screen display. The touch screen display may have an array of display pixels that are used to display images for a user. Touch input to the touch screen display may be provided by a user'"'"'s finger or other external object. A touch sensor in the display may have vertical and horizontal position sensors that are based on distinct touch sensor technologies. The position sensors may be based on strain gauge sensors or other force sensors, capacitive sensors having multiple elongated transparent capacitive electrodes that span the display, acoustic sensors, light-based sensors, and other types of sensors. An opaque masking layer in an inactive area of the display may hide some of the position sensor structures from view such as vertical position sensor structures. The horizontal position sensor structures may have minimal inactive regions along their edges.

19. A touch sensor display that has an active area surrounded by an inactive area and that is operable in response to a touch by an external object, comprising:
-
a display pixel array that emits light in the active area of the touch sensor display; a force sensor that measures a position of the touch on the touch sensor display with respect to a first lateral dimension without measuring a position of the touch on the touch sensor display with respect to a second lateral dimension that is perpendicular to the first lateral dimension, wherein the force sensor is formed in the inactive area of the touch sensor display; and a capacitive sensor that measures the position of the touch on the touch sensor display with respect to the second lateral dimension without measuring the position of the touch on the touch sensor display with respect to the first lateral dimension. - View Dependent Claims (20, 21)
