LIGHT GENERATING DEVICE AND DISPLAY APPARATUS HAVING THE SAME

摘要

A display apparatus includes a light source driving part generating a driving voltage in response to a control signal, a light source part generating a light in response to the driving voltage, a display panel receiving the light to display an image, a measuring part receiving the light from the light source part to measure a spectral power distribution of the light, an extracting part measuring optical data by elements of the light source part on the basis of the spectral power distribution and extracting optical characteristics by the elements on the basis of the optical data, and a light source controlling part controlling the control signal on the basis of the optical characteristics.
