Abstract
The invention relates to a manufacturing method for a screen for displaying an autostereoscopic image, including the steps of: selecting (E10) a block of pixels which are arranged in rows and columns, each pixel being composed of a plurality of sub-pixels of different colors; selecting (E11) a polarization film; manufacturing (E12, E13, E14) a lenticular array directly on the polarization film in order to form a composite film, called optical film; bonding (E15) the optical film to the block of pixels. The invention also relates to a method for converting a screen for displaying a two-dimensional image into a screen for autostereoscopic display.
Claims11
A method for manufacturing a screen for displaying an autostereoscopic image, comprising the steps of:
- selecting a block of pixels which are arranged in rows and by columns, each pixel being composed of a plurality of sub-pixels of different colors,
- selecting a polarization film having a first optical axis,
- manufacturing a lenticular array directly on said selected polarization film to form a composite film, called optical film, said lenticular array having a second optical axis, and
- bonding said optical film on said selected block of pixels so as to obtain a polarizing and lenticular display screen having two optical axes associated respectively with a polarization function and an autostereoscopic function.
A method for converting a 2D screen for displaying a two-dimensional image into a 3D screen for displaying an autostereoscopic image, said 2D screen comprising at least one layer of liquid crystals forming a block of pixels, overlaid at least by a polarization film, said method comprising the steps of:
- peeling said polarization film off of said 2D screen,
- selecting a polarization film,
- manufacturing a lenticular array directly on said selected polarization film to form a film, called optical film, and
- bonding said optical film directly onto said block of pixels of said 2D screen.
A method for manufacturing a lenticular array on a polarization film, comprising:
- applying a layer of transparent polymerizable resin on said polarization film,
- implanting said lenticular array in said layer of polymerizable resin, and
- polymerizing said polymerizable resin so as to obtain a transparent and stable composite film integrating said lenticular array.
