Claim Text:
1. A display screen comprising: a housing forming a casing; a display area on the front side of the housing; a printed circuit board placed inside the housing; at least one light-emitting diode forming a backlighting source for the display area, placed on one side of the printed circuit board, wherein the printed circuit board is a single-sided printed circuit board, wherein the display screen comprises a thermally conductive plate placed against that side of the printed circuit board which is opposite the side bearing the at least one light-emitting diode, wherein the thermally conductive plate comprises a lateral extension that contacts an exterior of the housing, and that is oriented perpendicularly to the printed circuit board, wherein a convection area of the lateral extension of the thermally conductive plate comprises lateral fins forming a heat sink, wherein the lateral fins are external to the housing, and wherein the lateral fins are disposed along a height of the lateral extension of the thermally conductive plate such that a length of the lateral fins extends in a direction that is parallel to a length of the thermally conductive plate, as viewed from a cross-section of the display screen; and a second double-sided printed circuit board having a smaller area than the single-sided printed circuit board, connected to said single-sided printed circuit board by at least one electrical connection and bearing at least one element for controlling the backlighting of the display area.
