Abstract: A display device includes: a pixel connected to each of a first scan line, a second scan line, and a data line; a scan driver supplying a first scan signal to the first scan line and a second scan signal to the second scan line; a controller dividing one frame period into an active period and a blank period and generating a count signal in which a time duration of the blank period is counted and a power control signal; a data driver supplying a data signal to the data line; and a power supply controlling a source driving voltage supplied to the data driver according to a duration of the blank period based on the power control signal. When the count signal reaches a reference value, the controller supplies a start signal for output of the first scan signal to the scan driver.

Abstract: The display device includes a first pixel connected to a first scan line and a first data line, a second pixel connected to a second scan line and the first data line, a scan driver configured to supply a scan signal to the first scan line and the second scan line, and a data driver connected to the first data line. The data driver provides a first data signal to the first pixel when the scan signal is applied to the first scan line, the data driver provides a second data signal to the second pixel when the scan signal is applied to the second scan line, and a length of a first period in which the first data signal is provided is different from a length of a second period in which the second data signal is provided.

Abstract: A display device includes: a screen saver operable to cause an image to be displayed with a lowered luminance in a screen save mode by lowering a scale factor from a first value based on the image being displayed as a still image longer than a reference time; and an overcurrent protection circuit operable to detect an overcurrent and cause a power of the display device to be turned off based on a predetermined current value that is reduced according to the scale factor and comparison between the predetermined current value and a driving current supplied provided to a display panel in which the image is displayed.

Abstract: A display device includes: a data mapping portion including a memory having addresses corresponding to locations of pixels and which maps an input image signal to a corresponding address; a pattern detector which detects an image quality deterioration pattern in pattern detection areas from the mapped input image signal; a pattern counting portion which generates pattern information by counting the image quality deterioration pattern; a data analyzing portion which divides the input image signal for each frame and selects a representative value of an input image signal of a frame; and a controller which generates an image data signal based on a first inversion method or a second inversion method by determining whether the counted number of the image quality deterioration pattern exceeds a threshold value based on the pattern information, and determines a level of a common voltage corresponding to the representative value.

Abstract: A display device includes a display panel, a first memory, and a degradation compensator. The first memory device stores stress data including degradation values representing a degradation degree of each of the blocks in the display panel. The degradation compensator loads the stress data from the first memory device, updates the stress data based on current input data and a maximum degradation value, updates the maximum degradation value based on degradation values included in the updated stress data, and generate compensated data by compensating for the current input data based on the updated stress data. The degradation compensator determines whether a first degradation value included in the stress data is normal by comparing the first degradation value with the maximum degradation value, and updates the first degradation value based on at least one adjacent degradation value adjacent to the first degradation value, when the first degradation value is abnormal.
