1. A display driver integrated circuit, comprising:
an input port configured to receive a display sensing signal for a display panel;
a circuit configured to generate a digital sensing value indicative of the display sensing signal;
a resistive random access memory coupled to the input port and configured to store the digital sensing value;
a display compensation logic coupled to the resistive random access memory to receive the digital sensing value from the resistive random access memory and configured to determine, based on the received digital sensing value, a compensation value to enable the display panel to modify a display control signal; and
an output port coupled to the display compensation logic to transmit a display compensation voltage signal to the display panel, wherein the display compensation voltage signal is generated based on the compensation value.
