A display device includes a display panel. The display panel has a visible-light transmissible polarizer at a side of receiving an external light, and includes a first optical sensor, a second optical sensor and a sensor output computing part. The first optical sensor is disposed on a substrate of the display panel and unsheltered by the polarizer for detecting the external light. The first optical sensor outputs a first signal in response to a detected wavelength component of the external light. The second optical sensor is disposed on the substrate of the display panel and sheltered by the polarizer for detecting a visible light passing through the polarizer. The second optical sensor outputs a second signal in response to a detected wavelength component of the visible light. According to the first signal and the second signal, the sensor output computing part computes a UV light intensity of the external light. |
