Display apparatus

A display apparatus comprises gate lines, GL, data lines, DL, and pixel driving power lines, PL, passing through a display area of a substrate. The display apparatus further includes a plurality of pixels, P, each having a pixel driving chip, 120, mounted on a pixel area defined on the substrate. The pixel driving chip is connected to adjacent gate, data and pixel power driving lines. It is also connected to a light emitting element, ELP, of the pixel. The display further includes a gate driving chip array, 200, and a data driving chip array, 300, mounted in a non-display area of the substrate each respectively connected to the gate lines and data lines. The pixel driving chip may further comprise a gate bump, a data bump, a power input bump and an output bump to connect the chip to the adjacent gate lines, data lines, power lines and the light emitting element. The display apparatus may further include a gate buffer chip, a plurality of data latch chips, a plurality of touch sensing chips, a timing controller chip, a digital to analogue converter chip, a power management chip and a DC-DC converter chip.
