1. A device comprising:
- a processor;
a display having a front side and a back side that is opposite to the front side;
a mid-chassis, the mid-chassis disposed beneath the back surface of the display;
a light transmitter configured to emit infrared (IR) light, the light transmitter being disposed (i) beneath the mid-chassis and (ii) proximate to a first side of the display, wherein the IR light emitted by the light transmitter defines a ray that is non-parallel to a plane defined by the front side of the display;
a light receiver configured to detect the IR light emitted by the light transmitter, the light receiver being disposed (iii) beneath the mid-chassis and (iv) proximate to a second side of the display, the second side being opposite to the first side; and
a lightguide that includes a plurality of reflective surfaces, the plurality of reflective surfaces being configured to receive the IR light from the light transmitter and direct the IR light across the front side of the display and towards the light receiver to implement touch sensing in association with the display,wherein the processor in conjunction with the display, the light transmitter, the lightguide, and the light receiver is configured to;
detect interference of the IR light on the front side of the display; and
determine location of a touch input on the front side of the display based on the interference.

Abstract
Some implementations include electronic devices having space efficient component configurations. In some instances, an electronic device may include an electronic display, a light source, and a lightguide having one or more reflective surfaces. This disclosure describes, in part, configurations of these and other components that create opportunities for efficiently using space associated with the electronic device.

7. A device comprising:
-
a display for displaying content to a user, the display having a front surface and a back surface opposite the front surface; a mid-chassis, the mid-chassis disposed beneath the back surface of the display; at least one light source operable to emit light, the at least one light source being disposed beneath the mid-chassis, wherein the light emitted by the at least one light source defines a ray that is non-parallel to a plane defined by the front surface of the display; and at least one lightguide configured to direct the light from the at least one light source to the front surface of the display, and cause the light to travel across at least a portion of the front surface of the display. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
providing a display that includes a front surface and a back surface that is opposite to the front surface of the display, and a mid-chassis, the mid-chassis disposed beneath the display; operating a light source to emit a ray of light that is non-parallel to a plane defined by the front surface of the display; reflecting the ray of light to produce one or more first rays of reflected light that propagate from beneath the mid-chassis to above the front surface of the display; and reflecting the one or more first rays of reflected light to produce one or more second rays of reflected light that propagate substantially parallel to at least a portion of the front surface of the display. - View Dependent Claims (18, 19, 20)
