Edge-to-edge display with a sensor region
A portable information handling system housing integrates a display having an edge-to-edge presentation of visual images at a housing portion with an inactive portion of a display panel along a perimeter of the display having a sensor region that provides access to underlying sensors through the display. A sealant and black matrix disposed in the inactive region limits illumination that escapes from an active region and provides an aesthetically appealing edge-to-edge appearance. Openings in the sealant and black matrix at the sensor locations provides access through the display, such as with index matching resin that passes illumination and a patterned covering of the black matrix.
1. An information handling system comprising:
a housing having at least one housing portion, the at least one housing portion having a rectangular shape with a housing portion perimeter of four sides;
a processor disposed in the housing and operable to process information;
a memory disposed in the housing and operable to store the information;
a display panel coupled over the at least one housing portion, the display panel having an upper surface that extends to the housing portion perimeter at the four sides, an active area that generates visual images within a visual image perimeter of less than the housing portion perimeter, and an inactive area disposed outside the visual image perimeter, the inactive area having a sealant, an opaque matrix and a sensor region; and
plural sensors disposed in the at least one housing portion, the sensor region aligned with at least one of the plural sensors and configured to pass light through the display panel to the at least one of the plural sensors;
wherein the display panel further comprises a polarizer upper surface coupled to a thin film transistor, the thin film transistor coupled over a color filter, wherein the sensor region lacks the polarizer upper surface;
wherein the sensor comprises an infrared camera and the sensor region has an opening in the opaque matrix sized to pass infrared images through the display, the opening having an index matching resin in the place of the sealant; and
wherein an infrared ink is disposed in the opening at the color filter bottom surface.
2. The Information handling system of claim 1 wherein the infrared camera comprises a user presence detection sensor.
