Description

[Detailed description of the invention] A series of field emission cathodes arranged in rows A flat, gunnel type display with The present invention relates to a flat panel display, particularly an electric field display. The present invention concerns a novel flat flannel-type display using an emitting cathode.

Generally, cathode ray tubes (CRTs) are used in monitors for computers, television receivers, etc. -The cathode ray tube is used as a component for video images, graphs, Used to display information composed of alphanumeric characters, etc. as images that can be seen with the naked eye. It is used. Such cathode ray tubes can be and/or have more hot cathodes. At these cathodes, the beam shape By combining various electrodes for generation, modulation and initial acceleration, multiple individual (diserete) To ensure that an electron beam can be formed. Do it like this The combination consisting of the above-mentioned electrodes and cathode made by It is called.

The deflection coil or electrode is placed across the plane of the phosphor coated anode screen. The direction of each electron beam traveling in the direction is controlled so that it points in the correct direction. (This deflection control means is better than an electrostatic electrode.) White electromagnetic coils are often used. This is because the electromagnetic field of the electron beam (This is because the characteristics are relatively good.)

The phosphor on the screen reacts with the electron beam when it collides with it, emitting visible light. .

CRTs for monochrome (black and white) televisions often have seven electron guns. CRTs for color television generally have three electron guns (or three electron beams). (Equipped with seven electron guns capable of firing electron beams) Fired from three electron guns for color television The emitted electron beam is placed on the anode screen at a predetermined distance between red and green. and blue phosphor dots (or phosphor strips), each with a separate impact strength. collide at a certain degree and form an image of the desired color. Discontinuous video elements on the screen Each displayed subarea is commonly referred to as a pixel (or picture element or pixel).

It can be used as a measure of the degree of resolution per unit area on the screen. and For example, the cathode ray tubes used in current ordinary color television receivers are approximately /tao, It is possible to provide ooo degree of noise. These pixels are divided into three generated in the raster 9 turf when the scanning electron beams collide with each other individually. It is something that

Cathode ray tube technology has advanced significantly, and by using these, alphanumeric Various types of displays such as character display dice and high-resolution image display displays are available. Information display displays can be manufactured. These displays display predetermined information. It can be displayed as a bright image. However, cathode ray tubes are generally quite long. It is something that you have. This is because, in order to properly control the scan, the electron gun assembly and This is because the distance between it and the clean must be considerably long. On the other hand, small Quite small, like a display for a computer [portable computer] There are many important technical fields that require the use of digital displays. therefore, Unlike ordinary cathode ray tubes, there is no need for sufficient depth, and brightness, resolution, Thoroughly looked at the display gray conditions such as wide range displayability and the conditions related to the required power. vinegar·! There are great expectations for the development of a channel-type display, and research into its development is active. It began to be held in This type of display is generally a flat/green panel display. It is called a play or quasi-planar Nornel type display.

A display screen (i.e. a cathodoluminescent screen) coated with a phosphor It is better to use a plasma discharge or other type of screen when using Lean. It is more advantageous for producing displays that meet the above conditions than when using A panel-type display that is considered to be made of plastic and has somewhat good characteristics that has been developed so far. Many of the rays use phosphor coated screens. In a 4-channel display (flat), one of the following two structures is generally used: A series of cathodes or The structure is such that multiple electron beams are generated from other electron beam generation sources. child In the case of the structure, the individual electron beams emitted from the matrix circuit are/or is used for a given pixel further, i.e. to excite it. child In some embodiments of the structure, strip cathodes are arranged parallel to each other. Electrons are emitted from the cathodes and used to create suitable electrodes or shielding members. A series of electron beams is formed depending on the application. The main drawback of this kind of structure is that the given M) A large amount of power is required to excite the beam emitting cathode in the 17727 circuit. It is generally necessary. Furthermore, in this type of structure, the brightness is uniform. It may also cause problems with fever (if you do develop a fever, (The heat must be removed by suitable means.)

Furthermore, it is possible to form images with sufficient resolution on fairly large displays. A matrix of attritable cathodes or other beam emitting sources such as Another disadvantage is that the circuit is difficult to manufacture. Those with the above structure generally have X-Y It often uses addressing technology. When using this technology In this case, long-term excitation of individual pixels becomes impossible.

This limits the brightness value of the screen (to overcome this drawback, , a long duty cycle excitation circuit is attached to the pixel addressing means. can be used. As will be easily understood, the installation of said circuit will address this issue. This is considered to be an extremely complex solution, and moreover, this circuit itself poses new problems. (In other words, the problem of reduced resolution also occurs). Opening this kind of matrix circuit Examples of cited documents include U.S. Pat.

This includes placing the screen on the side or rear of the display screen. be. In this case, the electron beam may be deflected by appropriate deflection means (e.g. the beam, e.g., by electromagnetic deflection means, electrostatic deflection means, or both). The object is to collide with the desired pixel location on the screen. child This type of equipment arrangement method is called the edge mount method. The main drawback of this structure is that It is a low degree. Because the minimum number of beams covers the entire screen. Because the desired video (image) must be repeatedly formed by sequential addressing. It is. Another drawback is that there are serious electro-optical problems, such as: .

This means ensuring that pixels are kept in the proper position for the purpose of creating high-resolution displays. This is a serious problem in that it is difficult to properly control the direction of the electron beam. There is a problem. Various methods have already been proposed to solve this problem. Examples include U.S. Pat. 7. Tata No. 603/, ≠ No. 27, No. 2 A 3. ! r2 number and temperature An example of this method is the method described in the specification of No. 3.

Composition of the invention The present invention provides an edge mount with favorable structural characteristics for matrix circuits. This invention relates to a flat panel display. This display is Type described in U.S. Patent No. j, 7rg≠77 (inventor Spind et al.) This was made possible by utilizing the unique characteristics of the field emission cathode. child Field emission cathodes of the type generally contain a fairly large number of electrons within a very small area. It has a child emission point. For example, a parcel of approximately o, o o o r inches in diameter Field emission cathodes with approximately 750 electron emission points in the area are currently available. .

The flat Gunnel type display of the present invention has a plurality of field emission cathodes arranged in a line. These electron guns are located at the seven edges of the display. emits a series of electron beams when excited, and these electron beams strike the plane of the screen. They proceed along separate paths that are closely parallel to each other. Defining individual pixels The beam is deflected to ensure that it impinges on the desired area within the screen. Deflection means is provided for directing.

Most preferably, it: forms part of the display image; Simultaneously excite a series of linearly arrayed pixels (preferably/pixels in a column) In order to to simultaneously excite a series of pixels in the next column, and repeat this operation sequentially to create a screen. Most preferably, pixels in the entire area of the lean are excited. of the present invention In some cases, in order to address locations on the screen in two directions, In addition, the beam is It is sufficient to perform the deflection in only one direction. In other words, the field emission cathode described above is The use of an electron gun with an electron gun eliminates the need for scanning in one direction and The direction control means (array) can be used to direct a row of beams in a direction having a different angular relationship. It is sufficient to provide only a deflection control means for deflecting it in the desired direction. this The deflection means in the case may be simple electrostatic means, and this A plurality of deflection electrodes are arranged parallel to each other in a plane approximately parallel to the plane of the screen. Most preferably.

Electrostatic deflection means require less power than electromagnetic deflection means.

As is clear from the foregoing description, the present invention applies not only to the previously described apparatus, but also to a novel scanning method. It also provides law. When using a deflection means that deflects in only one direction, According to the present invention, area scanning can be carried out even in cases where It is. The great advantage of this scanning method is that the entire series of pixels arranged in a line can be can be excited at once, i.e. many pixels can be excited simultaneously rather than individually. It is possible to excite 6 in each of the electron beams the desired individual pixel information The intensity of each beam is individually modulated to accommodate the According to this method, the brightness can be significantly increased. This is because the excitation of each pixel is performed over a relatively long duplex. This is because it can be done in a single cycle.

The present invention aims to improve beam alignment and/or calibration. It also provides a mechanism to do so with efficiency. That is, according to the present invention, the cathode means for detecting the electron beam emitted from the screen is provided near the second edge of the screen. You will be kicked. This detection means determines both the position and intensity of the electron beam. information about each individual e-visit can be detected and fed back. The launch conditions and direction of movement of the beam can be controlled.

The structure and effects of the present invention will become clearer from the detailed description below.

The flat panel (//) shown in the drawings is the simplest type of flat panel according to the present invention. This can be considered as a specific example. Display in flat panel (//) The screen (/2) responds to electron bombardment, as in the case of well-known screens. It can emit visible light. Screen (/2) Cathodoluminescent It has an inner surface (anode). In other words, this inner surface is one that electrons can collide with and that this electron bombardment It is a surface configured to emit fluorescent light (or phosphorescence) in response to a sudden change. paraphrase This screen is then made of transparent glass with a conductive coating, making it even more detailed. In other words, a thin film-like coating with/or more phosphors is applied to its inner surface. It consists of transparent glass with a conductive coating. As is clear to those skilled in the art, Other types of screens can also be used, for example with reflective and conductive coatings. Furthermore, a phosphor-containing coating is applied so that when electrons collide with the phosphor-containing coating, the desired cathode luminescence is achieved. Screens configured to produce mineral emissions can also be used.

It is shown in FIG. As shown, the panel (//) also has a shield grid (/3). This shielding grid (/3) is located near the inner surface of the display screen. be placed in place. To simplify the description, only a portion of the grid (/3) is shown. However, this is done using a conductive open wire mesh (open me, sh) according to well known techniques. ) or composed of strip-shaped electrodes as shown in the drawings. It may be. The purpose of the grating (/3) is to deflect the electron beam row during its deflection. [In this case, the deflected electron beam passes through the phosphor coating of the screen (/2). before accelerating toward the masked surface], the collision energy and collision angle of the beam The goal is to increase the As can be readily understood by those skilled in the art, such There may be cases where it is not desirable to have a shielding grid. Also, color selection etc. Preferably, means are provided for micro-positioning of the deflected beam for In some cases, several mutually insulated elements are placed next to each other for this purpose. It is also possible to use a grid.

In the present invention, an array of individually addressable electron guns ( /B) as part of this flat panel display, i.e., this The rows of electron guns (/2) are placed on the seven edges of the screen (/2).

This row of electron guns has a large number of field-generating cathodes, and the number of cathodes is determined by the display. The number of cathodes is the same as the number of lines of the ray, and these cathodes are perpendicular to the direction of the rows. It is preferable to point in the direction. The simplest example of a column is a linear column. can be lost. In other words, in this case, the electron guns are arranged in seven linear rows. . However, the term "linear array electron gun" as used herein refers to a linear array electron gun. Addressing of pixels (pi) cells (array in the form of seven lines) It also includes an array of electron guns arranged in such a way that the easily understood , a large number of columns of pixels can be divided into seven (or A group of electron guns are used one after another. For example, if the entire screen is With interlaced field lines, as in the case of television, which is scanned by If the device is configured to form an image frame, the For the purpose of sequentially scanning each field, multiple pixels adjacent to each other are Seven electron guns are used individually for each pixel to collide the child beams sequentially. It can be modulated. Preferably, the line is a straight line. . In the preferred embodiment, this line is a kelum (column) of pixels.

In order to reduce the number of electron guns required to create a row of electron guns (1), the following method is used. It is preferable to 6 each of the two opposite edges in Disgray a line of pixels from (i.e. a line consisting of pixel elements to be excited) ) appears, but among these λ edges, the edge with fewer lines appears. Preferably, there is a row (16) of electron guns in the section, whereby the field emission Minimizes the number of cathodes required and also allows standard displays Signal processing becomes very easy.

Figure ≠ shows an electron gun (/ 7) is a schematic diagram showing CI and (/). The cathode in these electron guns is For example, U.S. Patent No. 3. A　A　42≠No.1, No.3.7j 70≠and No. 3.7g? , 11-7/ specification (inventor Charles A. Spindo et al.) The electrodes may be of the types listed above. Multiple cathodes of this type share a common pace (2Q) from which a plurality of electron emitters (21) protrude for each electron gun. each The cathode of the electron gun works together with the emitter f(,2/) to emit electrons. Counter electrode or dart (22).

(23) and (2≠). This counter electrode is emitter chitsuzo. located at a certain distance from the It is. Counter electrodes (22), (23) and (2≠) are as shown in the drawing. They are placed at a certain distance from each other as shown in location (2). , the reason is that the individual cathodes (/7), (/r) and (l) are each individually This is to define (delin@ate).

By using an electron gun assembly with a field emission cathode that emits a stream of electrons. The following benefits can be obtained: As already mentioned, each field emission cathode is It has multiple electron emission sites that can emit relatively high-energy electron beams. , nevertheless its dimensions are very small. Furthermore, this excitation of the cathode results in heat. therefore, insulation measures are unnecessary and the source of thermal energy The use of is also unnecessary.

In order to ensure that the electrons emitted from each of the cathodes arranged in a row form an individual electron beam, Therefore, it is desirable to take measures suitable for this purpose. Examples of this means include A/4- The charging electrode (21I) and multiple acceleration/focusing electrodes (27) are connected to the electron gun section. It can be placed as a material. Electrodes (2j), (,27) and pace (20) is a common member for all of these electron guns. This focusing voltage The pole has an automatic focusing effect on all beams, i.e. the optimal It performs a focusing action.

Deflecting the beam to impinge on a predetermined area on the screen Provide means. In this preferred embodiment, the deflection means comprises a plurality of elongated electrodes (21 r) (Fig. 2), which are located at the rear of the space that is the path of the beam. Ru. A plurality of electrodes (2g) are arranged in an array for electrostatic field deflection (i.e., to ensure that the electrostatic field an array of deflecting members). As mentioned above, this electrostatic array is Generally, electromagnetic arrays also consume less power. As shown in the drawing, A number of electrodes (2g) generally define a plane parallel to the surface of the display screen. It is something to do. In the simplest embodiment, the electrode (2♂) is a silicone made of insulating material. Gubstrats (2), for example glass sheets, Bonding thin metal films (metalized strips) such as aluminum It can be manufactured by

As can be easily understood, in order to withstand the pressure differences caused by vacuum application, For example, between the screen (/2) and the sheet-like substrate (2) on the back side. It may be necessary to include a reinforcing structure, but this may not be possible if it is necessary to include a reinforcing structure. O may be unnecessary in the specific example Each of the cathodes is individually applied with an excitation voltage, thereby causing the An electron beam of desired intensity is emitted. The value of the desired intensity of this electron beam is It varies depending on the properties of the cell. For this purpose, a field emission cathode Attach a lead wire (31) to each counter electrode and connect it as shown in Figure 6. The desired beam intensity and its relative The corresponding voltage value will of course vary depending on the image on the display, etc. , this type of circuit can be formed according to conventional techniques. The timing of applying cathode voltage and Control operations related to video (image) processing, etc. are performed using the controller (33 units) as shown in Figure 6. In other words, the controller (33) takes the display signal (3 hiro) as the input signal. It receives the information and performs control.

Each of the deflection electrodes (2♂) can be individually operated. So Regarding a specific example, as shown in FIG. 2-deflection voltage supply source C37).

(3♂) and (3ri) are provided. Applying voltage to the deflection electrode and to the cathode The application of voltages matches or synchronizes their timing. Perform this operation φ In order to obtain a timing generator (pQ) as shown in FIG. will be established. The timing generator (≠O) receives a signal from the controller (33). It has an input part (≠l) for deflection, and an output lead wire (Hiro/), and this lead wire is Connected to voltage supply <37), (J♂) and (3ri). The timing mentioned above The synchronization mechanism ensures that the beams emitted from each cathode are deflected by the deflection system and focused. This will cause it to collide with Kusel.

Thus, for this pixel, the cathode beam intensity is measured instantaneously. all The cathodes of the It is best to stay in a nearby passage and proceed together. And these bees All of the pixels are deflected in the direction of the screen, and the pixels are placed adjacent to each other. If these beams are deflected together by the southern method, the result is A series of columns of pixels are excited in one direction, i.e. scanned in this direction. It is.

As mentioned above, a simple scanning system can be formed by the above method, and the brightness can be increased. be able to. This is because pixel elements are scanned at field rate rather than line rate. This is because it can be performed at a rate or a frame rate. Address individually An important feature of the present invention is that each electron beam is emitted from a cathode that can be I would like to draw your attention to this. The above-mentioned US Patent No. 1I-03/≠27 includes Although an in/line scanning method is disclosed, the simplified method described in this U.S. patent A simple device cannot perform such scanning to obtain images with sufficient resolution. This is also something worth noting.

The present invention enables precise beam alignment and calibration. This includes using a member arrangement that can be used. In other words, Yin A beam detector is placed at the edge of the screen opposite to the edge of the screen where the row of poles exists. A column of (≠≠) is arranged. Each of this detector has alignment and 6 beam detectors for each of the beams to be subjected to/or calibration/ Ru.

This line of detectors (lA+) has traveled close to the display without deflection. Arranged in a position that blocks the beam. In Figure 5, for example, the cathode (/7) The electron beam (4J’) and [11t] were emitted from and (/g), respectively. ) are placed in positions that respectively block each of the array detectors (4 4) and (≠7) are illustrated. The simplest example of each of these detectors and An example of this is a detector consisting of a plurality of anodes (3i) - (evening≠). No.! A diagram As best shown in (enlarged view), each detector has t anodes. For example, the anode (j/) is arranged in a square arrangement [as can be seen from FIG. and (≠2) and its lead wire are connected to the anode (Y3) and [YA≠] and its They should be kept away from the wires.]

The beam, whose direction of travel has been adjusted accurately, is distributed equally to all of the anode (Y/) - (YU≠). Place the anode plates so that they collide. The beam direction is slightly deviated from the specified direction. In this case, the amount of input current at these ≠ anodes will be different values. Dew. In other words, the amount of input current at the anode (Yu/) - (Yu≠) is compared with each other. By this, it is possible to know the degree of deviation of the beam from a predetermined direction, and also, You can also find out in which direction it is off. Connect each output side of this detector. Connect the beam from the conhalator to the 9-layer (31,) A signal regarding the degree of deviation from a predetermined direction of travel is transmitted. Each Kontsuk A lead wire (tough) is provided on the output side of the regulator (5B), and this lead wire is connected to each beam. Connect to a voltage supply to control the alignment electrodes of the system. Which mechanism is the ≠ and illustrated in FIG. Output side lead of comparator (5) The line (,5-7) is connected to the input side of the block (ri♂). Block (ri♂) The voltage applied via the output side (D'J - lead wire (tough) voltage that controls the operation of each of the contact electrodes.

The electrodes for each of the electron guns C/7), CI RI and (/RI) are shown in Fig. The electrodes are shown as (Otsu/), (Otsu 2) and (Otsu 3), respectively.

The sum of the current values of all ≠ anodes in the beam detector is the maximum of the impinging beam. This can be used as a guideline, as will be clear to those skilled in the art. Each inspection By connecting an adder (Otsu≠) to the output side of all anodes in the output device, From this, a signal representing the intensity of the beam can be emitted. Each adder (6 hiro) The output is fed back to the cathode voltage supply source as control information. this eye For example, connect the output side lead wire (6B) of the adder (B≠) to the cathode voltage. It is connected to the input side location (Otsu 7) of the pressure supply source (32).

Although not shown in the drawings, other detection means may also be used; This will be clear to those skilled in the art. For example, a plate detector (“detection grate”) ) can be used. A plate-shaped detector is installed at the edge of a plate-shaped body that has electrical resistance. It has an output lead whose output depends on the location of the beam impact point on this detector. This difference in output is used for the detection operation. This series of Regarding the usage of an array consisting of plate-shaped detectors, it is possible to use a plurality of different energize the beam sequentially, synchronize multiple outputs of the detector array, or Create a glodarum so that a certain beam corresponds to the output part, and identify the beam. This is what we do.

For the sake of brevity, this specification does not refer to electronic components as features of flat panel displays. Although described as being outside the mechanical component, the feedthrough The electronic components are encapsulated within the display device to minimize the number of components required. Preferably, the arrangement is in the form of an inclusion body. Electron gun control device and beam intensity/a Regarding arrays that perform alignment, it is best to arrange them using the above arrangement method. Particularly preferred.

Although preferred embodiments of the invention are described in detail herein, As will be apparent to those skilled in the art, the present invention may be modified in various forms without departing from its spirit. Various changes are possible. Therefore, the scope of the present invention is based on the description of the claims below. It should be understood that this should be determined based on the
