Abstract
The present invention relates to a drive chip for variably generating various types of control signals according to temperature changes so that high-quality image data can be provided to a display device, and an operation method thereof.
Claims10
A display driving chip comprising:
- an impedance matching circuit that matches characteristic impedance of a data channel and input impedance of the display driving chip;
- an equalizer circuit that compensates for distortion of data input through the data channel;
- a clock data recovery circuit that recovers an output of the equalizer circuit to match a clock signal;
- a realignment circuit that converts the input data into serial data;
- and
- a temperature control circuit including a continuous time linear equalizer circuit (CTLE) controller for adjusting an equalizing condition of an internal amplifier of the equalizer circuit in response to a temperature sensing signal, a bias controller for adjusting a bias of the internal amplifier, and an impedance controller for adjusting impedance of the impedance matching circuit.
