Patent ID: 7791717

Claim:
A system for testing a reflective display device, comprising: a testing apparatus, comprising: a plurality of light emitters configured for projecting light onto a reflective display device located on the testing apparatus; wherein the reflective display device reflects the light directly projected from the plurality of light emitters onto and covering all visible surface of the liquid crystal display; a plurality of light detectors configured for sensing reflected light from the reflective display device, and generating one or more electrical signals according to a luminance of the reflected light; wherein the light emitters and the light detectors are arranged on a platform of the testing apparatus in alternate columns; an analog-to-digital converter (ADC) module configured for receiving the one or more electrical signals from the plurality of light detectors, and producing a digital output according to one or more voltages of the one or more electrical signals; a microcontroller unit (MCU) configured for reading the digital output of the ADC module; and a computer for processing the digital output and displaying one or more results after processing.
