  • the LCD screens are composed of a matrix of RGB pixels, behind which are the cell of liquid crystal cells, and finally a back light that illuminates from behind this set and brings out the color images.
  • the transparent protective sheet is commonly called “lasérisable” because sensitive to laser radiation.
  • these color laser images may require, depending on the environment in which they are observed, a lighting that enhances the brightness of the image.
  • the object of the present invention is to remedy this drawback by proposing a method for producing an identity document, comprising a personalized color laser image which is backlit.
  • the subject of the invention is a method for producing a personalized backlit color laser image, comprising sub pixels with additive primary colors red green blue. These sub pixels are protected by a transparent lasérisable sheet. A laser beam makes appear by carbonization above each sub-pixel (R, G, B) in the transparent lasérisable protection sheet, the gray levels of a personalized color laser image.
  • the body of the document is transparent, and crossed by a luminous flux that retro-illuminates the personalized color laser image perpendicular to its plane.
  • the front of the identity document includes a lasérisable protection sheet that protects the sub-pixels (R, G, B) as well as decorations and anti-counterfeiting systems.
  • the back side is covered with decorations and anti-counterfeiting system, also protected by a transparent sheet laminated on the back of the identity document.
  • the luminous flux penetrates perpendicular to the plane of the document, through the rear face of the document through an opening made in the decorations and anti-counterfeiting systems,
  • the rear face is entirely covered with decorations or anti-counterfeiting systems.
  • the decorations and anti-counterfeiting system are pierced with tiny holes, evenly distributed, allowing the passage of a luminous flux from a source located at the rear of the identity document, and crossing it perpendicularly to its plane. This luminous flux illuminates the personalized color laser image from behind.
  • Decorations, anti-counterfeiting systems, and tiny holes are coated with a protective layer laminated on the rear face of the identity document.
  • the light penetrates through at least one side of the identity document, through its thickness.
  • Diffracting elements located under the custom color laser image diffuse and return the light at the rear of this image, and cross it perpendicularly to its plane.
  • Reflective means located on the rear face of the identity document accentuate the intensity of the light reflected through the personalized laser image.
  • the identity document is covered with decorations and anti-counterfeiting systems on both sides.
  • the invention also relates to an identity document, comprising a backlit color laser image illuminated by the implementation of the method above.
  • This identity document comprises a sheet of lasérisable material serving as a protective layer, this sheet being at least partially carbonized by laser radiation, sub-pixels (R, G, B) printed between the lasérisable sheet and a transparent document medium, these sub-pixels (R, G, B) forming an image backlit by a luminous flux which passes therethrough perpendicular to the plane of the document.
  • the figure 1 shows the section (10) of an identity document comprising a color laser image, according to the prior art. It comprises a document body (1) opaque, usually white. On its front face (12) a lasérisable transparent protective sheet (2) is laminated on sub pixels (R, G, B) (3) as well as on decorations and anti-counterfeiting systems (4). On the back (5) of the identity document are also decorations and anti-counterfeiting systems (4). The whole is protected by a sheet (9) laminated on the rear face (5) of the identity document.
  • a laser beam (6) by carbonization, generates the gray levels (7) in the lasérisable sheet (2) above each sub pixels (R, G, B), thus forming the gray levels a personalized laser color image.
  • This image is observed by the observer (8) by reflection of the ambient light on the personalized color laser image (3) through the lasérisable protection sheet (2).
  • the figure 2 shows the section (20) of an identity document according to a first embodiment of the invention, comprising a retro personalized laser image lighted.
  • the body of the document consists of a transparent sheet (11) by way of non-limiting examples, polycarbonate, certain polyvinyl chloride treated, acrylonitrile-butadiene-styrenes treated, or treated polyethylene terephthalates. It may consist of several laminated sheets. Its total thickness is between 50 ⁇ m and 1.5mm. It has on its front face (12) the transparent protective sheet (2) which has been laserized to form the personalized color laser image (3). To do this, a laser beam generates, by carbonization, the gray levels (7) above each sub-pixel (R, G, B), located between the transparent protective layer (2) and the transparent body (11).
  • the sub pixels (R, G, B) and their gray levels (7) constitute the personalized color laser image.
  • decorations and anti-counterfeiting systems, (4) are printed, except on the surface (22) facing the personalized color laser image.
  • the elements of the rear face of the identity document are protected by a transparent protective sheet (9) laminated on this rear face.
  • a stream of light (21) derived from an artificial source or ambient light passes through the transparent rear protective sheet (9), the transparent body of the identity document (11), through the opening (22) perpendicular to its plane, through the back passes the personalized color laser image and the protective sheet (2).
  • the personalized color laser image therefore, appears in transparency, effectively illuminated from behind, to the observer (8).
  • the figure 3 shows the section (30) of an identity document comprising a personalized backlit laser image, according to a second embodiment of the invention. It comprises on the front face (12) of the identity document, the same elements as those described above, in particular the personalized color laser image, composed of the sub pixels (R, G, B), the lasérisable sheet (4) levels of gray (7). It also includes decoration and anti-counterfeiting elements (4).
  • the rear face (5) of the identity document is coated with decorations or anti-counterfeiting elements on its entire surface.
  • the luminous flux enters through the rear face (5) of the document by tiny holes (23) distributed uniformly and practiced through the decorations and anti-counterfeiting elements, to the back of the personalized color laser image, to let the light from the source (24) pass perpendicularly to the plane of the document.
  • tiny holes do not degrade the quality of decorations or anti-counterfeiting systems, because they are not very visible. They have a diameter of between 5 ⁇ m and 500 ⁇ m.
  • This light, passing through these holes illuminates the personalized color laser image from behind. It is seen by transparency with a strong luminosity, by the observer (8).
  • the set of elements of the face rear (5) of the identity document is protected by a sheet (9) of transparent protection, laminated on the rear face of the identity document.
