Abstract

A system and method for maintaining similar optical performance over two electronic displays. A color light sensor is placed in front of the viewable area of each electronic display and is used to measure one or more optical properties in order to balance the two (or more) electronic displays. The user may be notified when a display is malfunctioning or the displays are not performing within acceptable ranges. The display may store optical data locally for later retrieval by the user. The user may access the optical data through a network connection with the display. One or more displays may be placed adjacent to one another and their optical properties may be measured and balanced so that the displays match one another or can be used as a harmonious array.

Claims

1. A system for maintaining similar optical performance over two electronic displays, the system comprising:

a first electronic display assembly;

a second electronic display assembly placed adjacent to the first electronic display assembly;

a color light sensor placed in front of each electronic display assembly; and

a network connection in electrical communication with the color light sensors.

2. The system of claim 1 wherein:

the network connection is in electrical communication with the internet.

3. The system of claim 1 further comprising:

a video transmitter in electrical communication with the electronic display assemblies.

4. The system of claim 1 further comprising:

a grouping of image-producing elements on the front of the display assemblies which are measured by the color light sensors.

5. The system of claim 1 further comprising:

a hot mirror filter placed between the color light sensors and the display assemblies.

6. The system of claim 1 wherein:

the electronic display assemblies are a liquid crystal displays.

7. The system of claim 1 wherein:

the electronic display assemblies are OLED displays.

8. A system for maintaining similar optical performance over two electronic displays, the system comprising:

a first and second electronic display placed adjacent to one another, each display having

an electrical backplane;

a display controller assembly in electrical communication with the backplane;

an electronic display assembly in electrical communication with the display controller assembly, the electronic display assembly having a plurality of image producing elements;

a color light sensor placed in front of the electronic display assembly and in electrical communication with the backplane;

a video input in electrical communication with the display controller assembly; and

a network interface in electrical communication with the backplane.

9. The system of claim 8 further comprising:

protective glass placed in front of each of the color light sensors.

10. The system of claim 8 further comprising:

a grouping of image-producing elements on the front of the display assemblies which are measured by the color light sensors of each display.

11. The system of claim 8 wherein:

the network interfaces are in electrical communication with the internet.

12. The system of claim 8 further comprising:

a hot mirror filter placed between the color light sensors and the display assemblies.

13. The system of claim 8 further comprising:

a user interface in electrical communication with the network interfaces.

14. The system of claim 13 wherein:

the user interface is a web browser.

15. The system of claim 8 wherein:

the electronic display assemblies are liquid crystal displays.

16. The system of claim 8 wherein:

the electronic display assemblies are OLED displays.

17. A method for maintaining similar optical performance over two electronic displays, comprising the steps of:

presenting two electronic displays placed adjacent to one another, each display having a plurality of image-producing elements with a color light sensor placed in front of a grouping of image-producing elements;

selecting an optical property of the electronic displays for measurement;

selecting a desirable range for the selected optical property;

driving each electronic display with its own set of performance variables;

displaying a test image with each grouping of image-producing elements using the performance variables for the electronic display;

measuring the selected optical property of the test images;

comparing the optical measurements to the desirable range; and

altering the performance variables of a display if the optical measurements for the display fall outside the desirable range.

18. The method of claim 17 wherein:

the displaying step comprises displaying a series of solid-colored shapes.

19. The method of claim 17 wherein the transmitting step further comprises:

establishing a network connection with the color light sensor;

providing a user with a web application capable of electrically communicating with the network connection;

allowing the user to receive optical data through the web application.

20. The method of claim 17 wherein:

the optical property is any one of the following;

luminance, color saturation, and contrast.

21. The method of claim 19 further comprising the steps of:

notifying the user when an optical property falls outside the desirable range.

22. The method of claim 21 wherein:

the notifying step comprises sending the user an email.

23. The method of claim 21 wherein:

the notifying step comprises sending the user a text message.
