Apparatus and System for Measuring Flicker of Display Panel

An apparatus for measuring flicker of a display panel, comprising a light guide tube, a measuring probe for flicker measurement, and an optical device for diverging light;

• the light guide tube comprising an opening at a first end and an opening at a second end, the trumpet-shaped light guide tube gradually enlarging from the opening at the second end to the opening at the first end:
• wherein the light guide tube is used for receiving light emitting from periphery regions and a center region of the display panel through the opening at the first end, the received light emerges from the opening at the second end and is transmitted to the measuring probe through the optical device, the optical device is an a light transmitting path between the opening at the first end and the measuring probe, and the measuring probe obtains flicker information of the periphery regions and the center region of the display panel based on the received light and acquires the flicker of the display panel based on the flicker information.
