Abstract
Official abstract text for this publication.
An apparatus and a system for measuring flicker of a display panel are disclosed. The apparatus comprises a light guide tube, a measuring probe for flicker measurement, and an optical device for diverging fight. The light guide tube comprises an opening at a first end and an opening at a second end. The trumpet-shaped light guide tube gradually enlarges from the opening at the second end to the opening at the first end. The opening at the first end is used for receiving light emitting from the periphery regions and the center region of the display. Light entering into the light guide tube through the opening at the first end emerges from the opening at the second end and is transmitted to the measuring probe through the optical device having a diverging effect. The more overall flicker information is acquired to improve the accuracy of measurement.
