Abstract

Compact hybrid developing machine that exposes a photosensitive substrate (1) using an LED or LCD display (2,3) wherein the substrate (1) is placed in direct contact with the image generating layer (colour generating layer+channelling layer) of the display (2,3). When the display is of LCD technology, the filters (21) of the colour generating layer are placed closer to the substrate (1) than the liquid crystal layer (22). In both types of display (2,3), a channelling layer is installed within the image generating layer, for example, a black matrix (4) of opaque elements. When using an LCD display (2), this may have a unifying filter (24) or a black translucent filter (25) before the light diffusing layer.

Claims

1-15. -15. (canceled)

16. A compact hybrid digital-analogue developing machine that exposes a photosensitive substrate (1) using an OLED or AMOLED type LED display or LCD display (2,3), characterised in that the substrate is placed in direct contact with the image generating layer of the display (2,3), which includes a colour generating layer and a light channelling layer formed by a black matrix (4) of opaque elements that surround each pixel or each colour generating element, placed in the colour generating layer or closer to the substrate (1).

17. The machine of claim 16, wherein the display uses LCD technology and the colour generating elements are filters (21) that are placed closer to the substrate (1) than the liquid crystal layer (22).

18. The machine of claim 17, wherein the filters (21) are placed between the polarizing layer (23) and the liquid crystal layer (22).

19. The machine of claim 17, wherein the filters (21) are placed between the polarizing layer (23) and the substrate (1).

20. The machine of claim 17, that has a black translucent filter (25) before the liquid crystal layer (22).

21. The machine of claim 17, that has the spectrum unifying filter (24) before the light diffusing stage.

22. The machine of claim 21, wherein the unifying filter (24) is selected from:

A tricolour film, with the RGB colours, spread over different areas of the pixel and whose surface areas are proportional to the percentage of the original intensity of each colour they should allow to pass through;

A red, magenta or yellow film.

23. The machine of claim 16 that uses at least one LED display (3) that forms part of a revolving roller (5).

24. The machine of claim 23 with at least two LED displays (3) on a pair of rollers (5) and wherein each LED display (3) occupies a fraction of the external surface area of the corresponding roller (5).

25. The machine of claim 16, wherein the LED display (3) comprises LEDs with a source of monochrome colour and the filters are placed closer to the substrate (1) than to the LED anode.

26. The machine of claim 16 that comprises several displays (2,3) with a total useful width that covers the total width of the substrate (1), and configured so that each display (2,3) exposes a different part of the substrate.

27. The machine of claim 16 that comprises equipment (12) to develop the substrate (1).

28. The machine of claim 16 wherein the substrate (1) has frangible sealed compartments with the developing liquids inside.

29. The machine of claim 28 that comprises a photographic camera.

30. The machine of claim 16, wherein the substrate (1) is used in a flexographic process.
