Abstract
A display apparatus and an operating method of the display apparatus are provided. The display apparatus includes a display panel, a light luminance sensing circuit, a controller, and a driving circuit. The light luminance sensing circuit senses luminance intensity to generate an output sensing signal. The controller receives the output sensing signal and converts the output sensing signal to generate selecting numeric information according to look-up information. The controller generates a control driving signal according to the selecting numeric information. The look-up information records a corresponding relation between a plurality of electric characteristic values and a plurality of pieces of numeric information. The driving circuit adjusts the luminance intensity of a lighting element according to the control driving signal.
