Abstract
A display device includes a display panel and a driving circuit that receives an input image signal and provides an output image signal corresponding to the input image signal to the display panel. The driving circuit includes an edge and slope detector that detects an edge of the input image signal, and determines an angle between the edge and a virtual line parallel to a first direction, a weight calculator that determines a weight, based on the edge and the angle, and a rendering module that compensates for the input image signal, based on the weight, and outputs the output image signal. The weight is determined through an arithmetic operation between the edge and the angle.
Claims20
A display device comprising:
- a display panel;
- and
- a driving circuit which receives an input image signal and provide an output image signal corresponding to the input image signal to the display panel,
- wherein the driving circuit includes:
- an edge and slope detector which detects an edge of the input image signal and determine an angle between the edge and a virtual line parallel to a first direction;
- a weight determiner which receives the edge and the angle from the edge and slope detector and determines a weight based on the edge and the angle;
- and
- a rendering module which receives the weight from the weight determiner and compensates for the input image signal based on the weight, and output the output image signal.
A method for controlling an operation of a display device, the method comprising:
- detecting an edge of an input image signal;
- determining an angle between the edge and a virtual line parallel to a first direction;
- determining a weight, based on the edge and the angle;
- converting the input image signal, based on the weight;
- and
- outputting the output image signal.
