Abstract: A display device is proposed, the display device including a display panel in which a plurality of unit pixels composed of n sub-pixels (where n is a natural number of 2 or more) connected to a data line and a gate line are arranged; a data driving circuit sequentially outputting n data voltages through a first output channel for one horizontal period; a latch circuit sequentially sampling the n data voltages input through the first output channel and providing the sampled n data voltages simultaneously to n data lines while maintaining the same for one horizontal period including a first time point at which a n-th data voltage is sampled; and a gate driving circuit supplying a scan signal to the gate line in synchronization with the data voltage supplied to the data line.

Abstract: A display device comprises: a panel comprising a pixel array; a data driver for outputting video data signals to the panel; and a latch part for receiving the video data signals from the data driver and outputting the received video data signals to the pixel array. With this configuration, the number of data drive ICs of the data driver can be reduced while maintaining the panel driving frequency.

Abstract: A display device for preventing a defective drive and improving reliability is disclosed. The display device includes a substrate including a display portion and a pad portion outside the display portion, a plurality of power lines positioned on the pad portion of the substrate and extended from the display portion, a plurality of data lines positioned in parallel with the plurality of power lines and extended from the display portion, and a plurality of bridge electrodes configured to connect at least two of the plurality of power lines. Some of the plurality of power lines include a power pad electrode on at least an end of the corresponding power line, and a number of the power pad electrodes is less than a number of the power lines.

Abstract: The present disclosure relates to a display having a narrow bezel structure. A flat panel display includes a substrate including a display area and a non-display area; a pull-up thin film transistor including a first gate electrode, a first source electrode and a first drain electrode, disposed in the non-display area; and a boosting capacitor disposed between the first gate electrode and the first source electrode; wherein the boosting capacitor includes a light shielding layer connected to the first gate electrode and overlapping with the first source electrode, but not overlapping with the first drain electrode.
