摘要： A timing controller includes a count control circuit, a pulse width detector, and a pulse generator. The count control circuit receives an external enable signal. Pulses of the external enable signal include an effective and a blank period of image data. The count control circuit counts pulse widths of each of the pulses. The pulse width detector receives the counted pulse widths, compares a pulse width of a present pulse with pulse widths of previous pulses, and detects a pulse width of a previous pulse that has a pulse width smaller than the pulse width of the present pulse. The pulse generator generates three output pulses having pulse widths that are one-third a period of the detected previous pulse. The pulse generator outputs the first, second and third pulses as an internal enable signal.

摘要： A display device displays an image with high display quality even if a temperature is changed, and includes a driving apparatus. Resistors having the same resistance value are used in a resistor string of a gray voltage generator, and a signal controller converts a number of bits of an input image signal into a signal having an increased number of bits. As a result, dynamic capacitance compensation processing and gamma curve modification can be separated from each other and performed independently when an ambient temperature of the display device is changed.
