A display device and a display driving method are disclosed. The display device includes a display panel including gate lines, data lines, and a plurality of subpixels including a plurality of driving transistors, a gate driving circuit configured to apply scan signals to the gate lines, a data driving circuit configured to convert image data into data voltages and apply the data voltages to the data lines, and a timing controller configured to compensate the data voltages applied to the plurality of driving transistors based on a real-time sensing process of characteristic values of the plurality of driving transistors, and control an application of a recovery voltage to at least one driving transistor of the plurality of driving transistors a plurality of times within a blank period of a frame period based on a reference period to reset the at least one driving transistor during the blank period.

Display device and display driving method

Disclosed is an organic light emitting display apparatus. The organic light emitting display apparatus outputs black gate pulses for a black image and sensing gate pulses for sensing in a vertical blank period and differently sets timings, at which the sensing gate pulses are output after the black gate pulses are output, for each gate line.

Organic light emitting display apparatus

Disclosed are a communication method, which is capable of being applied to a display device where a timing controller is provided in a system board instead of a display module, and a display device using the same. The communication method includes converting the digital video data and control signals into a transmission packet and transmitting the transmission packet from a first transmission module of a system board to a first receiving module of an interface board through a cable, restoring the digital video data and the control signals from the transmission packet, and transmitting the restored digital video data and control signals from the first receiving module to a display panel driver applying a plurality of driving signals to a display panel.
