  • Publication number: 20240112641
    Abstract: A display apparatus may include a first drive circuit configured to output a driving signal, the driving signal including a first period during which the driving signal has a first value, a second period during which the driving signal has a second value different from the first value, and a third period during which the driving signal has a third value between the first value and the second value; a second drive circuit configured to receive the driving signal and generate a gate signal based on the driving signal; and a display panel including a light emitting device that is configured to emit light based on the gate signal, wherein a length of at least one of the first period, the second period, or the third period is adjustable based on a temperature associated with the display apparatus.

  • Patent number: 9972243
    Abstract: A display device and a method of driving the same are disclosed. The display device includes a first driver integrated circuit configured to drive a first pixel array, a second driver integrated circuit configured to drive a second pixel array, a power module integrated circuit configured to receive an enable signal and output a driving voltage, and an AND gate configured to receive an output of the first driver integrated circuit and an output of the second driver integrated circuit and output the enable signal. The driving voltage output from the power module integrated circuit is commonly supplied to the first and second driver integrated circuits.
