Abstract

The interactive screen is the product of coupling by superposition or fusion of techniques of information acquisition and of graphic instructions by matrix mesh generation of two orthonormed layers of electrons sensitive to an electronic pointer with those of the iconographic restitution thereof by light-emitting diode doped nanometric polymer (conductive polymers). Said information acquisition and restitution peripheral is interactive in real time (and precise to the nanometre) according to manual graphic instructions. It represents an innovation in a graphic configuration computer from its digital slate versions to its interactive wall chart version.

Description

Interactive electronic screen for the acquisition and display of manually entered graphic information.

The present invention is part of the new information and communication technologies, also known by the acronym NTIC, and more particularly in the field of digital imaging.

It presents itself as the congruent and lasting solution to two still unresolved points of digital imaging:

1) - The direct digital acquisition of the pixel byte of information in the form of plots, graphs, handwriting and drawings, and more particularly recreated drawn animated images, with a view to their computer processing in 2D bitmap mode and / or 3D vector, authorizing the intervention at any time of interactive graphic manual instructions for the purposes of modifications, transformations and animations before recording and retransmission.

2) - The direct display of the byte to the pixel, public (collective), on a table and / or interactive wall screen, of all the images, recreated, drawn and of real shooting, animated or instantaneous, digitized, recorded, processed and / or calculated in 2D bitmap and / or 3D vector mode.

The digital acquisition of plots, graphs, handwriting and manual drawings, and more particularly that of recreated drawn animated images, their recording and their processing are currently done either by:

- Scanner or digital camera in 2D bitmap mode. - Tablet to digitize, decoupled from the display screen, in bitmap or 2D vector modes.

- Mouse and alphanumeric keyboard in 2D bitmap or 20 / 3D vector mode.

- Touch screen in bitmap or 2D vector modes (rarely).

This, in the most total inconsistency with the computing mode of animated images specific to computer science, the so-called "3D vector" mode, currently devoted only to "synthetic images", excluding any acquisition of information and any intervention by instructions in manual lines.

Their display, as well as that of animated or instant images, digitized in 2D bitmap mode by real cameras, is currently done either by: - Computer monitor with non-interactive screen.

- Cinematographic projection, once transferred to film support.

- Non-interactive electronic television screen, once transferred to magnetic media in analog mode and / or by telecine.

- Teleprojection or rear projection converting electronic, animated or instantaneous images, produced in analog or digital, into photonic images, counterfeiting interactivity. In other words, all systems currently implemented to ensure the transition between, on the one hand, the photo-analog and / or electro-analog moving images and the so-called digital images of the other, technologically incompatible, before passing these images to "all digital". The device according to the invention solves all of these incongruities in production as in diffusion due, for the first, to a wrong vision of the recreated drawn animated images and their history, for the second, to the hybrid systems therefore sterile implemented during the transition period that the images, more particularly animated, are currently experiencing

It is characterized, in particular, by the use of the electronic screen for restoring information by iconographic display - device for digital (byte) / analog (pixel) conversion - as such and, simultaneously, as a peripheral - information quisition - analog (pixel) / digital (byte) conversion device -, via an electronic pen. This, in the most immediate interactivity; direct from pixel to byte, round-trip in real time, while processing "graphic" information.

This interactive electronic screen is the characteristic peripheral of so-called "graphical" computers, to distinguish them from current office type computers with their alphanumeric keyboard, their mouse and their "passive" screen - of restitution of information only -, without however exclude the use of the keyboard. They range from the size of current pockets and laptops in the form of "digital slate" to that of current wall charts in the form of an "interactive board", all erasable and rewritable at will by electronic and computer processes. - * Their non-interactive version serves as a giant screen for the public display of all the animated images, whether they are real shots digitized in "2D bitmap" mode and / or recreated drawings calculated in "SD vector" mode "replacing all transient, hybrid, current systems.

This graphic computer in "digital slate" and / or "interactive whiteboard" version is intended to replace the current office type computers in all human activities requiring direct and interactive digital acquisition of all plots, graphs, handwriting and drawings, and more particularly drawn recreated animated images, for their simplicity of use and their extreme speed of execution, and this, whether in isolated use, individual, personal, and / or combined, collective, grouped; disconnected or interconnected in a network See Figures 3 & 4. Plates 3/4 & 4/4.

The interactive electronic screen of this graphic computer is made up of eight nanometric films of polyester and polymer superimposed; five electronically active including one in three layers and three neutral serving, one, of isolator between the acquisition device and that of restitution, the first of protection and the eighth, at the bottom, opaque, being able to serve as reflector as much as support to the seven superimposed. The five superiors are transparent. See Figure 1. Board 1/4. 1 - The first transparent polyester film is electronically neutral. It serves as protection for the lower films. Its upper surface is resistant to the tip of the electronic pen.

2 - The second film is the anode of the device for acquiring information by traces. Its circuits are aligned horizontally.

3 - the third film is the cathode of the information acquisition device. Its circuits are arranged in the vertical direction.

This orthonormal mesh allows the computer to record the position of the electronic pen on the surface of the screen / slate / electronic board to the nearest pixel. 4 - The fourth transparent polyester film is electronically neutral. It is used to separate the information acquisition part of the device from its restitution part.

5 - The fifth film carries the anodes of the electrical supply system of the information display device. It is coupled to the seventh.

6 - The sixth film is a triple polymer treated to carry light-emitting diodes. It is he who ensures the iconographic display of the digitized information. It is made up of three layers obeying two distinct technological and industrial options: a) - The diode option. Each of the three layers emits respectively in the wavelengths "blue", "green" and "red", following an appropriate treatment by electronic doping. b) - the RGB filter option. The anode layer coupled to the cathode layer emit white light: the filter layer separating it in the wavelengths "blue", "green" and "red". Each of them received appropriate treatment by electronic doping.

7 - The seventh film carries the cathodes of the electrical supply system of the information display device. It is coupled to the fifth.

It is conceivable to arrange for films five and seven (5 & 7) to serve as an information acquisition device in place of films two and three (2 8.3) in addition to their function of supplying the device display information. In which case three levels of films can be saved during manufacture. See Figure 2. Plate 2/4.

8 - The eighth film serves as a support for all of the seven superimposed. It can be treated to serve as a light reflector to the upper layers.

9 - It is the computer housing which contains the parts used for automatic information processing, alphanumeric by keyboard, graphic with the interactive screen and sound by microphone or DVD, on which the screen is placed above described, whether in "digital slate" or "interactive whiteboard" version.

Figure 1 attached shows an interactive screen in section, coupling / overlay version. Figure 2 shows the same screen in its merged version. Figure 3 shows three basic models of the digital slate and Figure 4 shows an electronic board and interconnected digital slates.
