ABSTRACT:
A display test system includes a symbol source and a controller connected to the symbol source for receiving a symbol in response to a testing event whereupon the controller causes the display to produce a first area having a first light intensity, and the symbol at a second light intensity within the first area. A viewer uses an input device to verify to the controller the ability to discern the difference in light intensities of the symbol and the first area by describing or identifying the symbol.
