Abstract
A method for manufacturing a coloured electronic display screen (10) including an active cell (11) and at least one polariser film (114) having an optical layer (115) and a tinted adhesive layer (116) via which the polariser film (114) is bonded to the active cell (11).
Claims3
A method for manufacturing a coloured electronic display screen (10), comprising the following steps:
- obtaining a polariser film (114) comprising an optical layer (115) on which an adhesive layer (116) extends;
- dyeing the adhesive layer (116);
- and
- bonding the polariser film (114) to the active cell (11) by means of said adhesive layer (116),
- wherein the dyeing step includes immersing the polariser film (114) in a dye bath so that the contents of the bath diffuse into the adhesive layer (116), the dyeing step successively comprising an operation of dip-coating the polariser film (114), an operation of rinsing the polariser film (114), an operation of drying the polariser film (114) and an operation of cutting the polariser film (114) so that it has given dimensions.
