Abstract:
1. A display panel comprising a first panel, a second panel, an illumination sensor and a determination unit, wherein the illumination sensor includes: a plurality of color filters disposed on a peripheral area of the first panel, the peripheral area of the first panel surrounding a display area of the first panel; and a plurality of photo sensors disposed on a peripheral area of the second panel corresponding to the peripheral area of the first panel, at least two photo sensors of the plurality of photo sensors opposing at least two different color filters of the plurality of color filters, wherein the plurality of photo sensors generate a plurality of output voltages, respectively, at least two of the plurality of output voltages are responsive to intensities of light which pass through the at least two different color filters, the determination unit outputs a first control signal based on the plurality of output voltages, and the determination unit includes a lookup table in which magnitudes of the plurality of output voltages corresponding to the at least two different color filters are classified based on spectral characteristics of an external light.
