Abstract
This disclosure relates to a device and method for detecting performance of panel driving circuit. The device comprises a plurality of point light sources, a plurality of optical fibers, a light source driving circuit and a detection circuit. The predetermined point light sources are corresponding to predetermined optical fibers, the predetermined optical fibers being one optical fiber or multiple optical fibers of a predetermined combination corresponding to elements of the panel driving circuit. The optical fibers are configured for transmitting the light emitted by the point light sources onto the elements of the panel driving circuit. The detection circuit is for obtaining a performance parameter of the element of the panel driving circuit based on a corresponding relationship between an intensity of illumination for the element of the panel driving circuit and a current value of the element as well as an output signal of the panel driving circuit.
