The present disclosure relates to a clock generator and a display device including the same. The clock generator includes a first clock generation circuit configured to output a clock, data, and a timing control signal; a first wiring through which the clock is serially transmitted; a second wiring through which the data is serially transmitted; a third wiring through which a pulse of the timing control signal is serially transmitted; a second clock generation circuit connected to the first clock generation circuit through the first wiring, the second wiring, and the third wiring and configured to generate pre-clocks in which phases are sequentially shifted based on the data and the clock; and a clock adjustment circuit configured to receive the pulse of the timing control signal and the pre-clock and output an output clock.

Clock generator and display device including the same

A level shifter according to an embodiment and a display device using the same are discussed. The level shifter includes a driving signal generation circuit configured to output driving signals through signal lines, and a pseudo signal generation circuit configured to generate phase-inverted pseudo signals of the driving signals. The pseudo signal generation circuit can raise or lower a voltage level of the pseudo signals by a variation magnitude adjusted according to the driving signals whenever a section with the driving signals overlapping on a time axis occurs.

Level shifter and display device using the same

The present disclosure provides a light emitting display apparatus including a display panel displaying an image, a power supply supplying a driving voltage to the display panel, a data driver supplying a data voltage to the display panel, a timing controller controlling the power supply and the data driver, and a sensing circuit unit receiving a feedback component of the driving voltage as a feedback voltage and selectively sensing an electrically stabilized period in the feedback voltage based on an internal control signal of the power supply.

Light emitting display apparatus and driving method thereof

An apparatus and method creating a ghost-free High Dynamic Range Image (HDRI) based on filtering are provided. It is possible to effectively prevent a ghost phenomenon from occurring when a single HDRI is created from a plurality of LDRIs, by defining a ghost area using a probability based on a global transfer function indicating a relationship for intensities of several frames, rather than searching for or identifying a ghost area in a single or each image.
