Conventionally, images are formed by electrostatic development of discrete areas containing charges, and the charges in each discrete area are It is known to grade loads and generate images.

As an example of prior art, Jonah Blumentos, published October 5, 1971, Reference may be made to U.S. Pat. No. 3,611,419 to Paul. In this patent, small An array of electrodes is arranged in rows on a conductive plate to dynamically generate an electrostatic latent image on the dielectric. The dielectric is moved between the small electrode and the conductive plate while a patterned electric field is generated. , the latent image of which is made visible by applying toner of selected polarity in a known manner. A capable electrographic imaging system is described.

Another example described in U.S. Pat. No. 3,774,168 to Tzu Kai Koo et al. A system-access semiconductor memory device is a block-like device on an unconnected substrate. It has a series of integrated circuit wafers arranged on it, but the control is carried out by means on the opposite side of the substrate. The memory device uses an energy beam that scans across blocks. operated by the system.

R.A. Cora U.S. Patent No. 3.329.96, issued July 4, 1967. In No. 2, strips arranged at right angles separated from each other by an insulator are arranged in rows. and arranged on an insulating dielectric substrate in a column-shaped formant and energized. generates a beam of electrons or ions that creates an electrostatic latent image on the recording material. A solid-state lightning transformer is listed, and Sugo's apology for lightning is a joke. be made visible.

In the modified form, the cola is composed of strips superimposed at right angles, arranged in the same plane at right angles. An embodiment is described in which the conductor is replaced by a row of conductors. This patent is based on quantum mechanics selected to cause electron emission to occur in the air gap as a result of the channel effect. refers to the electric field generated in the insulating layer placed between the electrodes.

As yet another example of prior art, U.S. Patent No. 3.97 to Jack S., Kilbey et al. No. 9.757 and No. 3. , No. 979.758. One of these patents In many cases, a large number of electrodes are placed on the surface of the module, and the charge on each electrode is controlled. Each can be energized by using a system register.

These electrodes are energized by individual, separate bistable circuit means; Generates what is currently commonly referred to as the "intermediate, iPl" effect, i.e. different tones. It refers to the grading of precipitated products.

The purpose of the present invention is to provide several improvements to this technique, particularly Some improvements have been made in the structure and method of this kind of module. That is. Another Old Testament is a picture that is a phenomenon, a possibility, and can be visually indicated. To be able to generate images or to store images in a computer; The objective is to provide a module capable of projecting an image onto a module. The aim is to form images on modules with high resolution and with integrated circuits known today. The objective is to provide modules that can be easily constructed using road techniques. Other purposes are Two things will become clear from the description of the invention.

Although the present invention is arranged such that the substrate, the row electrodes, and the column electrodes are overlapped with each other, electrically at least partially separated from each other by a semiconductor interface; rows and columns of electrodes disposed on the substrate and spaced apart from the substrate; Although it is partially electrically separated from the electrode, is it controlled? via mll transistor an imaging plate connected to the electrodes and disposed on each electrode, thereby performing nuclear imaging. A module characterized in that the temporary electrode forms part of a capacitor in association with its adjacent electrode. Provide joules.

In this way, when the electrodes of a row and column are energized accordingly, the discrete electrodes of each month The associated imaging plate receives or receives no charge depending on the type of image being reproduced. Conditioned to receive either no or graded charge.

The imaging plate can of course be given a positive or negative charge of any size, and an electric field exists. The imaging plate is made visible by applying a developer of opposite charge in the area Become. If it is desired to use the module to store optical images, the imaging plate have mW of light on them or can be formed of a photoconductor. That's it A light image is applied to the photoconductor, and the data of the image is stored by a computer. The image can then be read out and reproduced at any time for reading or reprinting. can be called.

Accordingly, the present invention allows images to be created in a relatively compact assembly in conjunction with a computer. Provides a highly effective system for storing and defining.

According to the invention, an optical image is converted into a digital latent image via a photoelectric imaging device. This allows the operator to view the image for checking, editing, and making changes at will. The statue can be summoned again. Once this operation is complete, a permanent optical image is created. The operator must transfer the modified image to a photoelectric imaging device to obtain an image or record. Can be done.

The advantage of the imaging device according to the invention is that it can be imaged without the aid of a CRT or laser scanning device. The point is that Joule can be imaged electronically.

Diagrams and information created on or by a computer are photoelectric images in optical form. Can be permanently stored in the transducer. This image can be used on any computer The system can also be used for optical viewing or electronic access through conversion.

Data and images in the photoelectric module can also be viewed optically using a conventional lens system. be able to. Furthermore, after the image is optically expressed, it is permanently fixed by a reproduction fluid. It can be held in a temporary digital state until

This photoelectric imaging module is electrically inactive until it is electrically enabled. It is dynamic. Therefore, the module can be installed without protection from magnetism, light, heat, or moisture. It becomes possible to memorize in an appropriate environment. Even in this disabled state, the module The roll can be read optically.

Such photoelectric imaging modules, like magnetic tapes and disks, require re-energization. do not have. The materials used in its manufacture are inorganic, and the liquid that makes the image permanent has a long lifespan. Thermoplastic resin or modified carbon liquid that produces information recording means for stable permanent record preservation of life is the main thing.

A typical module images a pair of tiny particles placed on a writing surface with their outer surfaces exposed. It consists of a board with a board. Each imaging plate of the pair has a column--switched by integrated circuit means. It is electrically readable via the column matrix.

The method of writing to a photoelectric image module is to set it to its neutral state by means of an electronic control circuit. consists of switching from a state to an active state, in which data is switched to the module. For example, by using a bias plate in close proximity to the photoelectric imaging module, It becomes a permanent optical image. These microelectrodes and vias are tested in the presence of reproducing solution. An electric potential is generated between the plates, causing charged particles in the liquid to rapidly migrate towards the active electrode. make it happen. The bias plate is used to control and stimulate the flow of negative riN particles. Therefore, this process will be strengthened. After removing the bias plate, the release agent may be aspirated or The permanent image thus formed is optically removed on the module. can be inspected.

Electronic reading of optical images involves the use of zero graphs on electrodes that are energized to form the image. Applying an insulating film by means of a film and then non-volatile between the electrode and the optical image Electron transfer occurs where a conductive liquid is added and the electrode is covered with an insulating film. This is done by applying a voltage to ensure that the voltage does not change.

This method allows complex electronic images to be formed rapidly due to the high cycling speed of integrated circuits. It will be done.

This imaging module electrically and optically notes in an easily readable manner. It has created an extremely compact high-capacity storage system that makes it possible to inspect Produces high quality optical images with high speed and high speed electronic access.

A robust module is formed with a writing surface on an imaging plate consisting of scattered areas.

These imaging plates are addressable and can also be used to store images on a computer. or can be scanned by a computer to store the image on a selected medium. It has become. The use of a photoconductor on an imaging plate allows optical images to be recorded directly on a computer. I can remember.

Therefore, by selectively energizing the rows or columns, each imaging plate is independently energized. Similarly, applying a potential directly to the imaging plate or by means of a photoconductor layer is possible. , can be added to a computer in an addressable manner. Photoconductivity of each imaging plate The surface is coated with developer particles, such as a liquid developer that produces fine-resolution dot images. is made visible so that it can be read directly.

The method of imaging the writing surface onto the addressable module defined above is a selected imaging plate on the writing surface of the module to image an electrostatic image on the writing surface; by the computer to provide a signal to the computer and store the image in computer memory.
