The present invention provides a method for the treatment of individuals diagnosed with a childhood behavioral disorder such as autistic spectrum disorders or combined type Attention-DeficitHyperactivity Disorder by administering an effective amount of memantine. Selection of graphical elements andor between graphical elements can cause activation of the set of transducers associated with the selected elements. Because the pixel electrodes are formed directly on the substrate, without forming an insulator layer in the pixel area, the transmission can be enhanced.
