Abstract: A selector according to an embodiment of the present disclosure includes a first electrode; a second electrode disposed opposite to the first electrode; an ion supply layer disposed between the first electrode and the second electrode to be on the side of the first electrode and doped with a metal, wherein the doped metal diffuses toward the second electrode; a switching layer disposed between the first electrode and the second electrode to be on the side of the second electrode, wherein the doped metal diffuses from the ion supply layer into the switching layer so that metal concentration distribution inside the switching layer is changed to generate metal filaments; and a diffusion control layer inserted between the ion supply layer and the switching layer, wherein the diffusion control layer serves to adjust electrical characteristics related to the generated metal filaments as the amount of the diffusing metal is adjusted in proportion to a thickness of the diffusion control layer.

Abstract: A display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. The capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.

Abstract: A method and an apparatus for serial data communication employs a data transmission process which transmits data from one control unit to the another control unit and at the same time checks a reception confirmation signal on each number of the data by transmitting a clock signal, and a data reception process which receives the data on the one control unit from the other control unit and checks a transmission confirmation signal on the each number of the data by transmitting the clock signal. The apparatus comprises a first and a second control unit, four serial buses for performing serial data communication between the both control units, two pull-up operation units for continuing control voltage of the serial buses at a certain level, and a control voltage matching unit for continuing voltage equilibrium condition.

Abstract: An apparatus and method for high speed detection, storing, and switching broadcast channels. The broadcast signal is discriminated to exist based an automatic gain control signal. This discrimination is done at a very high speed by the use of speed-up drive units. The invention also performs channel storing and switching operations at high speed by using speed-up drive units.
