Abstract
A display device according to the present disclosure includes a substrate including a display area which has an irregularly shaped side and a non-display area which includes a notch area defined by a shape of the irregularly shaped side of the display area and is disposed to enclose the display area. A load amount of the scan output signal of the display area in which the irregularly shaped side is formed is detected by a plurality of sensing lines and an offset of a data signal is corrected based on the load amount to improve an image quality of the display device including an irregularly shaped side.
Claims14
A display device, comprising:
- a substrate including a display area which has an irregularly shaped side and a non-display area which includes a notch area defined by a shape of the irregularly shaped side of the display area and is disposed to enclose the display area;
- a plurality of gate lines divided to be disposed in a left display area and a right display area due to the irregularly shaped side of the display area;
- a plurality of data lines in the display area;
- and
- a plurality of sensing lines disposed in the notch area and connected to the plurality of gate lines to transmit a scan output signal output from the plurality of gate lines;
- a load detecting unit detecting a scan load difference of the display area due to the shape of the irregularly shaped side based on the scan output signal transmitted from the plurality of sensing lines;
- and
- a data driver correcting an offset of a data signal based on the scan load difference detected by the load detecting unit and outputting the offset to the plurality of data lines,
- wherein when a quantified scan load amount difference outputted from a load difference quantifying unit is larger than a predetermined value, the data driver corrects the offset of the data signal so as to apply a data voltage which is higher than the data voltage set based on a data control signal applied from a timing controller, and when the quantified scan load amount difference outputted from the load difference quantifying unit is smaller than the predetermined value, the data driver corrects the offset of the data signal so as to apply a data voltage which is lower than the data voltage set based on the data control signal applied from the timing controller.

A display device, comprising:
- a display panel including a display area with a plurality of pixels for displaying images and a non-display area surrounding the display area, wherein the display area includes a plurality of gate lines extending in a first direction and having different lengths and a plurality of data lines extending in a second direction which is different from the first direction;
- a load detecting unit configured to detect a scan load amount due to a length difference of the gate lines, the load detecting unit further configured to quantify and output the scan load amount;
- and
- a data driver configured to correct and output an offset of a data signal applied to the plurality of data lines based on an output value output from the load detecting unit;
- wherein when a quantified scan load amount difference outputted from a load difference quantifying unit is larger than a predetermined value, the data driver corrects the offset of the data signal so as to apply a data voltage which is higher than the data voltage set based on a data control signal applied from a timing controller, and when the quantified scan load amount difference outputted from the load difference quantifying unit is smaller than the predetermined value, the data driver corrects the offset of the data signal so as to apply a data voltage which is lower than the data voltage set based on the data control signal applied from the timing controller.
