A head-up display including a display screen including an array of display pixels arranged in rows and in columns, where the display screen is pivoted, around an axis perpendicular to the screen, by an inclination angle between 10 and 80 degrees, with respect to the position of the display screen for which a group of adjacent activated display pixels of a same row appears to an observer as being directed along the horizontal or vertical direction.

Head-up display providing an improved viewing comfort

The invention relates to a matrix display screen which includes, in sequence: a mounting (); at least one first metal portion (); a stack of layers () including transistors (TFT, TFT); and organic light-emitting diodes ().

Display screen having organic light-emitting diodes

The invention concerns an organic light-emitting diode comprising a lower electrode () and an upper electrode (), an electroluminescent organic layer (), and at least one doped organic layer () in contact with one of said electrodes. The invention is characterized in that the doping is carried out using an alkaline-earth element or lanthanide, and the diode is heat-treated at temperature preferably not less than 60&#xb0; C. for more than one hour. The invention enables the lighting performance of the diode to be considerably improved.
