Abstract
A display that contains a sparse array of light-emitting diodes (LEDs), system, and method of fabrication are disclosed. The display includes a panel having at least one tile configured to display information. The panel is disposed within or on a transparent material. Each tile includes an array of LEDs, which have a uniform distance therebetween such that light from the array is viewable on opposing sides of the panel while providing visibility through the panel. A darkening layer on at least one side of the panel provides selectable darkening to block the light from exiting the at least one side of the panel.
Claims17
A dual-sided display, comprising:
- a panel having at least one tile configured to display information, the panel disposed within a transparent material, each of the at least one tile including an array of micro light-emitting diodes (microLEDs), the microLEDs configured to provide light to be viewed on opposing sides of the panel, a distance between the microLEDs configured to provide visibility through the panel;
- a first darkening layer disposed on at least one side of the panel, the first darkening layer configured to provide selectable darkening to block the light from exiting the dual-sided display on the at least one side of the panel;
- a sensor configured to make a determination as to a condition of a detection of a user presence and receipt of a user input on a side of the display;
- and
- a processor configured to control the first darkening layer to provide the selectable darkening to an opposite side of the display as the side of the display at which the condition of the user presence is detected by and the receipt of the user input from the sensor.
A display panel configured to display information, comprising:
- a sparse array of micro light-emitting diodes (microLEDs) configured to provide light to be viewed on opposing sides of the panel;
- a darkening layer disposed on each side of the array, each darkening layer configured to provide selectable darkening to block light from exiting the panel and configured to be independently activatable between a transparent mode and an opaque mode;
- a sensor configured to make a determination as to a condition of a detection of a user presence and receipt of a user input on a side of the display;
- and
- a processor configured to control each darkening layer to provide the selectable darkening to an opposite side of the display as the side of the display at which the condition of the user presence is detected by and the receipt of the user input from the sensor.
