摘要： In a display apparatus according to one or more embodiments, a boosting circuit boosts an input voltage to a backlight driving voltage, and a backlight unit receives the backlight driving voltage to generate light. A backlight driving circuit controls the boosting circuit in response to a dimming signal and compensates a plurality of feedback voltages from the backlight unit to output a panel driving voltage. A panel driving circuit receives the panel driving voltage from the backlight driving circuit to output a data voltage corresponding to an image signal and receives a gate driving voltage to generate a gate voltage. A display panel displays an image in response to the gate voltage and the data voltage. Accordingly, a number of the boosting circuits for the display apparatus may decrease, thereby reducing a manufacturing cost of the display apparatus.
