Abstract: Disclosed is a thin film stress control-based coating method for large-area coating. The method uses a two-step coating process in which a first coating layer that is a relatively low-hardness layer is primarily formed on a base member and a second coating layer that is a relatively high-hardness layer is secondarily formed on the first coating layer. The method can form a high-density coating structure that is hardly peeled off over a relatively large area compared to conventional coating methods by suppressing internal stress of the coating layers of the coating structure. Further disclosed is a coating structure manufactured by the same method.

Abstract: A display driving device includes an interface, a clock generator, a sync signal generator and a timing controller. The interface receives a first vertical sync signal having a first vertical period, a first horizontal sync signal having a first horizontal period shorter than the first vertical period, and image data. The clock generator generates a clock signal having a predetermined frequency. The sync signal generator generates a second vertical sync signal using the first vertical sync signal, and generates a second horizontal sync signal having a second horizontal period different from the first horizontal period, using the clock signal, when a porch period included in the first vertical period is greater than a predetermined reference value. The timing controller drives a display panel based on the second vertical sync signal and the second horizontal sync signal.
