Abstract
A testing device for testing one more characteristics of an electronic display. The testing device includes a main body and a receiving cavity defined within the main body configured to receive at least a portion of the electronic display. The testing device also includes a plurality of sensors positioned on a first surface of the testing device and configured to be in optical communication with at least a portion of the electronic display received within the cavity. The plurality of sensors is configured to detect at least one type of non-uniformity of the electronic display by detecting light emitted from the electronic display.
Claims19
A device for testing one or more characteristics of an electronic display comprising:
- a main body;
- a receiving cavity defined within the main body and configured to receive the electronic display, wherein the receiving cavity is defined by a first surface surrounded by a plurality of sidewalls, wherein the sidewalls define a rectangular shape that substantially matches the shape of the electronic display, wherein the sidewalls have a top surface, and wherein the electronic display is contained entirely below the top surface of the sidewalls when in the receiving cavity;
- a plurality of sensors positioned on the first surface and configured to be in optical communication with the electronic display received within the receiving cavity, wherein the plurality of sensors is configured to detect at least one type of non-uniformity of the electronic display;
- a cover that prevents light from entering the receiving cavity;
- and
- an output mechanism on the cover, wherein the output mechanism comprises a grid of lights, wherein each light has a location that corresponds to a location of a respective sensor on the first surface of the receiving cavity.
A method for detecting one or more non-uniformities in an electronic display comprising:
- providing a testing device having one or more sensors, wherein the testing device has an interior and an exterior;
- collecting, by the one or more sensors, light data corresponding to light emitted from the electronic display over a time period, wherein the one more sensors are on the interior of the testing device;
- and
- with an output mechanism on the exterior of the testing device, displaying the light data as it is collected.
A testing apparatus for detecting two or more characteristics of a display for a computing device comprising:
- a main body;
- a receiving cavity defined within the main body and configured to receive at least a portion of the display;
- a first group of sensors positioned on a first surface and configured to be in optical communication with a first portion of the display received within the receiving cavity;
- and
- a second group of sensors positioned on the first surface and spatially separated from the first group of sensors by a portion of the first surface, the second group of sensors configured to be in optical communication with a second portion of the display received within the cavity, wherein the portion of the first surface is free of sensors, wherein the first and second group of sensors are configured to detect at least one type of non-uniformity of the display, wherein the first group of sensors and the second group of sensors are phototransistors, wherein the first group of sensors and the second group of sensors create a two-dimensional image of light emitted from the display.
