  • Publication number: 20240127746
    Abstract: A light emitting display device includes a display panel including a first pixel group including a plurality of pixels in 2N rows. The light emitting display device further includes a second pixel group disposed subsequent to the first pixel group and including a plurality of pixels in 2N rows. The light emitting display device further includes an emission signal unit including a first emission stage for applying the same first emission signal to the first pixel group and a second emission stage for applying the same second emission signal to the second pixel group. In a first frame, a falling time of the first emission signal and a rising time of the second emission signal are different from each other.

  • Patent number: 10769085
    Abstract: A bus system is provided. A bus system includes a slave functional block and a master functional block. The master functional block transmits a first command to the slave functional block. The slave functional block includes a first bus protector. The first bus protector receives the first command on behalf of the slave functional block and transmits a dummy signal corresponding to the first command to the master functional block in response to the slave functional block being in a state of not being able to receive the first command or not being able to transmit a response signal corresponding to the first command.
