Abstract: A dynamic characteristic-reflected shoreline evaluation system and a method thereof are proposed. The system may include a data collection processor configured to collect various types of information for shoreline evaluation with respect to an evaluation target region. The system may also include a shoreline evaluation processor configured to determine a shoreline rank by reflecting static characteristics and dynamic characteristics of the evaluation target region on a basis of data collected through the data collection unit. The system may further include an output processor configured to output the various types of information comprising an evaluation result of the shoreline evaluation unit and an overall process and result of the system. The system may further include a communication processor configured to transmit and receive various types of data through wired or wireless communication with an external device. The system may include a controller configured to control an overall operation of the system.

Abstract: A liquid crystal display device capable of controlling a viewing angle is disclosed. The liquid crystal display device includes: a liquid crystal panel configured to include a plurality of quad type pixels each consisted of red, green, blue, and viewing angle control sub-pixels; and a timing controller configured to reply to a viewing angle mode selected by a user and apply red, green, and blue data and any one of a wide viewing angle control data, a first narrow viewing angle control data, and a second narrow viewing angle control data to the liquid crystal panel. As such, the LCD device controls a range of viewing angles, thereby allowing the image to be viewed from every direction or not to be viewed from the left and right directions or the upward diagonal directions in the center of the user. In other words, the LCD device can limit the image display according to the positions of the persons adjacent to the user.
