Abstract: An apparatus for downloading control frequency code data, a multi-purpose remote controller, and a mobile communication terminal used as the same, for downloading control frequency code data with respect to each of electronic equipment sets, loaded in a server, and automatically setting each to perform a remote control function. An apparatus for downloading control frequency code data further comprising a server in which control frequency code data with respect to each of the electronic equipment sets is loaded, a communication terminal for downloading the control frequency code data with respect to each of the electronic equipment sets loaded in the server through the Internet, and a multi-purpose remote controller for executing a predetermined program to automatically set the frequency code data with respect to each electronic equipment set, provided by the communication terminal, thereby performing a remote control function corresponding to the control frequency code.

Abstract: A method for measuring an image-sticking defect in a liquid crystal display device includes steps of irradiating light from a backlight to the liquid crystal display device, displaying a first full white state on a liquid crystal display screen of the liquid crystal display device to which the light is irradiated, measuring first luminance values of a plurality of designated points on the liquid crystal display screen, calculating an average luminance value of the first full white state using the first luminance values, displaying a full black state on the liquid crystal display screen, measuring second luminance values of the plurality of designated points on the liquid crystal display screen, calculating an average luminance value of the full black state using the second luminance values, forming a gray scale using the average luminance value of the first full white states and the average luminance value of the full black state, displaying a second full white state on the liquid crystal display screen, and
