Abstract
An image display apparatus and a method for driving the same are provided. The image display apparatus includes a display panel including a light emitting element formed in a pixel area defined by intersection of a plurality of scan lines and a plurality of data lines, the display panel being configured to display an image by controlling the light emitting element, a discharger configured to perform a discharge operation of the plurality of scan lines by time-division control with respect to a discharge line connected to the plurality of scan lines in the number less than the plurality of scan lines, and a controller configured to control the light emitting element and the discharger.
Claims14
An image display apparatus comprising:
- a display panel comprising a light emitting element formed in a pixel area defined by intersection of a plurality of scan lines and a plurality of data lines, the display panel being configured to display an image by controlling the light emitting element;
- a discharger configured to perform a discharge operation of the plurality of scan lines by time-division control with respect to a discharge line connected to the plurality of scan lines, wherein a number of discharge lines is less than that of the plurality of scan lines;
- and
- a controller configured to control the light emitting element and the discharger,
- wherein a control signal provided from the controller to the discharger has a predetermined duty-on time based on a short-circuit state of the light emitting element connected to the plurality of scan lines.
A method for driving an image display apparatus, the method comprising:
- displaying an image by controlling a light emitting element formed in a pixel area defined by a plurality of scan lines and a plurality of data lines;
- and
- performing a discharge operation of the plurality of scan lines by time-division control with respect to a discharge line connected to the plurality of scan lines,
- wherein a number of discharge lines is less than that of the plurality of scan lines, and
- wherein a control signal for controlling the discharge line has a predetermined duty-on time based on a short-circuit state of the light emitting element connected to the plurality of scan lines.
