Abstract:
1. A display panel comprising: a first substrate with an active region and at least one peripheral region, said active region comprising a plurality of pixels, and each of the pixels comprising at least one switch element electrically connected to a signal line; a second substrate corresponding to and overlapping the active region so as to expose the peripheral region, and comprising a common electrode thereon; a display medium with a dielectric coefficient disposed between the first substrate and the second substrate; at least one first photo-sensor disposed on the peripheral region and composed of a first semiconductor switch element, said first photo-sensor(s) being adapted to detect a whole light spectrum of an environmental light with a visible light spectrum and an invisible light spectrum; at least one second photo-sensor disposed on the first substrate and composed of a second semiconductor switch element, said second photo-sensor(s) being adapted to detect the visible light spectrum of the environmental light; and a photo-sensing circuit electrically connected to the first photo-sensor(s) and the second photo-sensor(s), said photo-sensing circuit being adapted to obtain a value of the invisible light spectrum (Vi) of the environmental light.
