Abstract: A display apparatus is provided. The display apparatus includes a substrate having a data line disposed thereon, a plurality of pixel modules arranged in a matrix format on the substrate, and a driver providing a digital data signal through the data line to each of the pixel modules. Each of the pixel modules may include a light emitting layer in which a plurality of light emitting diode (LED) devices form a pixel, a driving layer comprising a display driver integrated circuit (DDI) below the light emitting layer and generating a driving signal to drive the LED devices, and a substrate layer, between the driving layer and the substrate, comprising a data input pad to receive the data signal and transmit the data signal to the DDI and a data output pad to provide the data signal to another adjacent pixel module.
