Abstract: A light emitting cell for use as a pixel, the light emitting cell being configured to generate the three primary colors and to form different color tones therewith, comprising: a light emitting front surface, a rear surface, and a substrate arranged between the front and rear surface; a light source carried by the substrate; three luminous sections, comprising a blue luminous section, a light converting red luminous section, and a light converting green luminous section; and a primary color selection device capable of performing a repetitive movement at a certain frequency so that, during this movement, one of the luminous sections is alternately selected as a potential light emitting section, characterized in that the primary color selection device is a single mechanical component that serves to select all three luminous sections.
