Abstract
A display apparatus displays an image in a normal driving mode at a low temperature where a response speed of a liquid crystal becomes lower than a critical value, and displays the image in an impulsive driving mode at a higher temperature where the response speed of the liquid crystal becomes higher than the critical value.
Claims19
A display apparatus, comprising:
- a display panel to display an image;
- a temperature detector to detect an ambient temperature and output a signal corresponding to the detected ambient temperature;
- a comparator to compare the signal output from the temperature detector with a reference value and to output a control signal corresponding to the comparison result;
- and
- a driving mode selector to select either a normal driving mode or an impulsive driving mode in response to the control signal.

A method of driving a display apparatus, comprising:
- displaying an image;
- detecting an ambient temperature;
- outputting a signal corresponding to the ambient temperature;
- comparing the signal with a reference value;
- outputting a first control signal when the signal is higher than the reference value, and outputting a second control signal when the voltage is lower than the critical voltage;
- and
- selecting either a normal driving mode or an impulsive driving mode in response to the first control signal or the second control signal.
