  • Publication number: 20170092222
    Abstract: A display device includes: a timing controller for generating a data configuration packet including a temperature reference voltage bit, a self-adaptive bit, and a first heating control bit; a data driving IC including a digital signal processor and a temperature sensor; and a pixel portion connected to data lines for displaying an image. The temperature sensor senses a temperature, outputs an enable-level abnormal temperature detecting signal when a temperature sensed voltage indicating the temperature is greater than the temperature reference voltage. The digital signal processor generates a feedback heating control bit to reduce the temperature sensed voltage to a value less than the temperature reference voltage when the detecting signal is at the enable-level. The digital signal processor controls heating of the data driving IC irrespective of the first heating control bit and according to the feedback heating control bit when the self-adaptive bit is set to an ON state.
