Patent ID: 8188441

Claim:
A display apparatus for detecting an ultraviolet (UV) intensity, the display apparatus comprising: a lower substrate comprising a first photo sensor, a second photo sensor, and a third photo sensor for detecting an intensity of light, from the external of the display apparatus, of a first band, a second band, and a third band and converting the intensity of the light in the first band, the second band, and the third band into a first current, a second current, and a third current respectively; an upper substrate disposed opposite to the lower substrate; and a processing unit coupled to the first photo sensor, the second photo sensor, and the third photo sensor, for receiving and processing the first current, the second current, and the third current so as to only obtain a UV intensity of a UVB band, wherein the ranges of the second band and the third band are comprised within the range of the first band wherein the first band is a band of sunlight, and wherein the second band and the third band are bands of visible light.
