Abstract
The present invention is directed to a display device such as a liquid crystal display including: a horizontal clock counter and a vertical clock counter which count each clock signal every horizontal cycle and every vertical cycle for a valid data period of a data enable input signal; and an input signal generating section for holding a count value and generating an input signal in a driver IC and a driving circuit corresponding to a resolution of the display device which is obtained at that time by utilizing a count value held at a last time for a next horizontal cycle or a next vertical cycle, the display device being applicable to the driver IC and the driving circuit which can be used for the display device having various resolutions.
Claims2
A display device such as a liquid crystal display comprising:
- a data valid period selecting section for controlling a valid data enable input signal corresponding to a display screen mode selected in response to a selecting input signal sent from the outside wherein said data valid period selecting section has a function of selecting the display screen mode to be displayed with an optional display size;
- and
- an input signal generating section for recognizing, in response to the selecting input signal, a value of a resolution which is obtained at that time, thereby generating an input signal corresponding to the recognized resolution for use in a driver IC and a driving circuit of the display device which is on use at that time.
An interface circuit for a display device comprising:
- a data valid period selecting section for controlling a valid data enable input signal corresponding to a display screen mode selected in response to a selecting input signal sent from the outside wherein said data valid period selecting section has a function of selecting the display screen mode to be displayed with an optional display size;
- and
- an input signal generating section for recognizing, in response to the selecting input signal, a value of a resolution which is obtained at that time, thereby generating an input signal corresponding to the recognized resolution for use in a driver IC and a driving circuit of the display device which is on use at that time.
