Abstract (en)
[origin: WO2012062981A2] The invention relates to a display screen comprising: a housing forming an enclosure; a display surface on the front face of the housing; a printed circuit board arranged inside the housing; and at least one light-emitting diode that forms a back-lighting source for the display surface and is arranged on a face of the printed circuit board. The display screen is characterised in that the printed circuit board is a single-face printed circuit board, the display screen comprises a thermoconductive plate arranged against the face of the printed circuit board opposite the one carrying the at least one light-emitting diode, and the display screen also comprises a second double-face printed circuit board that has a smaller surface than the single-face printed circuit board, is connected to said single-face printed circuit board by at least one electrical connection, and carries at least one element for controlling the back-lighting of the display surface.
