Abstract (en)
[origin: WO2015159030A1] The invention relates to an image-generation system (10) for a display, in particular a head-up display, including a liquid-crystal screen (12) and a device (14) for backlighting said screen (12). The projection system is characterised in that said backlighting device (14) includes: a supporting plate (18); at least one light-emitting diode (16) arranged on the supporting plate (18) and emitting light towards the screen (12); and a wall (28) comprising a reflective inner surface defining a space between the supporting plate (18) and the screen (12), said wall (28) extending above at least one portion of the supporting plate (18) such that the inner surface of the wall thus extended enables light to pass through towards the screen (12) and reflects, towards the screen (12), light propagating towards the supporting plate (18).
