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.

Display device and method of compensating for degradation of the display device

A display device includes: a low drop-out ('LDO') regulator which provides a second power voltage to a power line during a first period of one frame; a buck converter which provides a first power voltage to the power line during a third period of the one frame; and a pixel connected to the LDO regulator and the buck converter through the power line. A voltage level of the second power voltage is equal to a voltage level of the first power voltage.

Display device and driving method of the same

A display device according to an embodiment includes a display panel including a plurality of pixels, and an image sticking compensator configured to generate a second image data by reflecting an age data accumulated in a first image data input from an external source. The image sticking compensator generates the age data by accumulating a deterioration data generated by reflecting a frequency weight corresponding to a determined frequency of a previous frame to an image data of the previous frame after the image data of the previous frame is stored.

Display device and method of driving the same

A display device includes a first power source, a timing controller, and pixels. The timing controller is connected to the first power source through a main line, an auxiliary line, and a detection line. The pixels are commonly connected to the first power source through a first power line. The first power source includes: a main power source connected to the first power line and the main line; an auxiliary power source connected to the auxiliary line; a rectifier connected between the auxiliary power source and the first power line; and a comparator comparing a voltage of the first power line and providing its output to the detection line.

Display device and driving method thereof

Provided are a block based video decoding method and an apparatus thereof, the method includes receiving a bitstream; generating a prescan information corresponding to a picture unit image from the bitstream; and decoding the picture unit image of the bitstream using the prescan information. The bitstream includes the image information in which the picture unit image is divided into one or more coding unit and sequentially block-coded according to a predetermined order in the coding unit, and the decoding comprising processing a block decoding in accordance with the predetermined order in the intra-picture in a non-dependent manner with an encoding order in an intra-coding unit using the prescan information.
