## Abstract

A portable information handling system display integrates a MIMO antenna configuration that cooperates with a radio to adapt display operations for supporting wireless communication. For example, plural antenna nanowires integrated with display pixel control wires selectively interface with a MIMO radio with the antenna wires selected based upon display operational characteristics, such as the presentation of visual information at the display and the enablement or disablement of touch detection circuits.

## Claims

### Claim 1

A portable information handling system comprising:
a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
a graphics processor operable to selectively send visual information to present visual images at pixels of a display and to selectively turn off presentation of visual images at the pixels by withholding visual information from presentation at the pixels;
an OLED display integrated in the housing and interfaced with the graphics processor, the OLED display operable to present the information as visual images and having control wires interfaced with pixels to communicate signals to the pixels that generate the visual images;
plural antenna wires integrated with the OLED display at plural locations, the plural antenna wires aligned to pass across the display with the control wires; and
a radio interfaced with the plural antenna wires, the radio having a multiple input multiple output (MIMO) controller operable to communicate wireless signals from the plural antenna wires in a MIMO configuration;
wherein the graphics processor selects less than all pixels of the display at which to disable the presentation of visual information based upon activity at the antenna wires, the disabled visual information associated with control wires that are proximate to but separate from the antenna wires to reduce signal interference between the control wires and the antenna wires.

### Claim 2 (depends on 1)

The portable information handling system of claim 1 wherein the plural antenna wires comprise silver nanowires.

### Claim 3 (depends on 1)

The portable information handling system of claim 1 wherein the housing comprises a main portion rotationally coupled to a lid portion, and the display comprises an OLED film disposed at both a front face and a rear face of the lid portion.

### Claim 4 (depends on 3)

The portable information handling system of claim 3 wherein the plural antenna wires comprise at least one antenna wire disposed with a control wire on the front face and at least one antenna wire disposed with a control wire on the rear face.

### Claim 5 (depends on 1)

The portable information handling system of claim 1 further comprising:
a thin film transistor (TFT) touch surface disposed on the display to detect end user touches; and
a touch controller interfaced with the TFT touch surface and operable to control operation of the TFT touch surface;
wherein the touch controller selectively disables the TFT touch surface proximate the plural antenna wires based upon activity at the plural antenna wires to reduce interference between the plural antenna wires and the touch surface.

### Claim 6 (depends on 5)

The portable information handling system of claim 5 wherein the activity at the plural antenna wires comprises selection of the plural antenna wires to receive wireless signals in a MIMO configuration.

### Claim 7 (depends on 1)

The portable information handling system of claim 1 wherein the activity at the antenna wires comprises selection of the antenna wires to receive wireless signals in a MIMO configuration.
