Disclosed is a clock recovery system of a display apparatus including a clock recovery unit which uses changeable option information used for recovering a clock signal and defining a duty, generates delayed clock signals having the duty corresponding to the option information in a clock training section, and outputs one of the delayed clock signals as the clock signal.

Clock recovery system of displays apparatus

The present invention relates to a display apparatus which drives a display panel to display an image, and a driving circuit thereof. The display apparatus includes a timing controller configured to provide a control option having a value for compensating for pixel data and a gray scale, and a driving circuit configured to combines the control option and the pixel data and output an output voltage.

Display apparatus and driving circuit thereof

A source driver may include: a transmission line configured to transmit an output signal of a sample and hold circuit which stores pixel information of an organic light emitting diode (OLED) cell; an amplifier is formed a first offset voltage at an input terminal by a parasitic capacitor of the transmission line; and an offset voltage storage unit configured to store the first offset voltage outputted from the amplifier as a second offset voltage while the transmission of the output signal of the sample and hold circuit through the transmission line is turned off, and offset the first offset voltage by providing the second offset voltage to the input terminal of the amplifier when the output signal of the sample and hold circuit is transmitted through the transmission line.

Source driver of display device

The present invention relates to a source driver of a display apparatus, and relates to a source driver for display apparatus insensitive to power noise, which forcibly decides an internal operation state as normality in a specific period including a power noise generation period and operates insensitively to the power noise. Accordingly, the display apparatus can normally output an image voltage even though power noise occurs.

Source driver less sensitive to electrical noises for display

A sample and hold circuit may include: a main sample and hold circuit configured to sample and hold pixel information of an organic light emitting diode (OLED) cell, and output a first output signal; and a dummy sample and hold circuit configured to sample and hold a reference voltage in synchronization with the main sample and hold circuit, and output a second output signal for offsetting a switching noise signal contained in the first output signal.
