  • Patent number: 10249232
    Abstract: When multiple display panel drivers are set to a state in conformity to given specifications, setting data indicative of details of the setting is stored in a memory. One of the display panel drivers supplies a first signal indicating that the setting data is in a readout condition to the memory and other display panel drivers. In response to the first signal, the memory reads and provides the setting data on the first line. The one display panel driver fetches the setting data on the first line to perform the setting based on the setting data. The other display panel drivers fetch the setting data from the first line in response to the first signal to perform the setting based on the setting data.
