发明名称 Mesh Designs for Touch Sensors
摘要 In one embodiment, an apparatus includes a touch sensor that includes a mesh of conductive material configured to extend across a display that includes multiple pixels. Each of the pixels has a first pixel pitch (PPx) along a first axis and a second pixel pitch (PPy) along a second axis that is substantially perpendicular to the first axis. The first pixel pitch is a distance between corresponding features of two adjacent pixels along the first axis, and the second pixel pitch is a distance between corresponding features of two adjacent pixels along the second axis. The mesh includes first lines of conductive material that are substantially parallel to each other and second lines of conductive material that are substantially parallel to each other. The first lines are configured to extend across the display at a first angle relative to the first axis.

主权项 1. An apparatus that comprises: a touch sensor that comprises a mesh of conductive material configured to extend across a first display, wherein: the first display comprises a plurality of pixels, wherein: each of the pixels has a first pixel pitch (PPx) along a first axis and a second pixel pitch (PPy) along a second axis that is substantially perpendicular to the first axis;the first pixel pitch is a distance between corresponding features of two adjacent pixels along the first axis; andthe second pixel pitch is a distance between corresponding features of two adjacent pixels along the second axis;the mesh comprises first lines of conductive material that are substantially parallel to each other and second lines of conductive material that are substantially parallel to each other;the first lines are configured to extend across the first display at a first angle relative to the first axis, wherein the first angle is within 1° of the arctangent of[3m×PPyPPx], wherein m is an integer; the second lines are configured to extend across the first display at a second angle relative to the first axis, wherein the second angle is within 1° of the arctangent of[3n×PPyPPx], wherein n is an integer; first lines that are adjacent to each other are separated from each other along the first axis by a first-line separation distance that is within 1% of(p3×q×PPx), wherein p and q are integers; second lines that are adjacent to each other are separated from each other along the first axis by a second-line separation distance that is within 1% of(r3×s×PPx), wherein r and s are integers; a portion of one or more of the first or second lines comprises a sinusoidal variation with a peak-to-peak amplitude of less than or equal to 30 μm; andthe mesh of conductive material has a metal density of 3% to 5%; and one or more computer-readable non-transitory storage media coupled to the touch sensor and embodying logic that is configured when executed to control the touch sensor.
