An electron emission device includes a substrate, an anode electrode formed on the substrate, phosphor layers formed on the anode electrode, and resistance layers formed on the substrate and electrically connected to the anode electrode. The heating element includes a first surface, a second surface opposite the first surface, a third surface extending between the first and second surfaces, and a fourth surface extending between the first and second surfaces, opposite the third surface. The method also includes supplying power to the circuit based on the time duration and the update rate, and latching the signal at the update rate. According to another aspect of the invention, media assets can be grouped into collections and transferred on a collection basis.
