Original Abstract Submitted
A light emitting display apparatus can include a power supply unit to supply power to a light emitting display panel having light emitting elements, a printed circuit board on which the power supply unit is mounted, chip-on-films connected between the printed circuit board and the light emitting display panel, data drivers mounted on the chip-on-films, a control driver to control the power supply unit and the data drivers, low-voltage lines extended from the printed circuit board to the light emitting display panel through the chip-on-films, and a main low-voltage line disposed on the printed circuit board and connected to the low-voltage lines and the power supply unit. Also, the light emitting display apparatus can include sensing capacitors connected to the main low-voltage line, in which each of the sensing capacitors is connected to one of the data drivers.
