The thermoelectrons generated by this process are extracted as an electron beam through an aperture provided in the grid electrode 6, and then the electron beam is modulated by the grid electrode 7.As a modulation method, each electron beam passing hole is electrically This is done by dividing the electron beams into two and applying individual beam modulation voltages to each electrode.Then, after passing through the aperture of the shield electrode 8, the individual modulated electron beams pass through the aperture of the vacuum envelope 1. It travels straight between the phosphor 2 provided on the inner surface and the vertical scanning deflection electrode 30 provided on the inner surface of the vacuum envelope 4 provided opposite to it.

The vertical scanning deflection electrode 3 is composed of divided electrodes with a number of 6 h/゛ lines between the horizontal scanning lines. A low potential (VD-Vcc) is sequentially applied to the fluorescent surface 2, and
At the potential part, the electron beam travels straight, and at a potential lower than the fluorescent surface 2, the electron beams traveling straight are influenced by the electric field and are deflected all at once toward the fluorescent surface 2, causing the fluorescent surface 2 to be deflected.

By sequentially applying voltages VD, VD-Vcc), the straight electron beam is sequentially scanned from the top to the bottom of the screen, so that a two-dimensional display can be performed on the phosphor 2.

Problems to be Solved by the Invention However, in the above-described configuration, the electron gun that generates the electron beam needs to generate an electron beam equal to the number of picture elements in the horizontal direction of the screen. In normal color television, the picture elements are approximately 0.1 to 0.2 mm, and generating and modulating the electron beam at this pitch requires microfabrication of the electron gun and electrical signal application. This poses considerable difficulties in terms of the means to do so. In addition to these problems, due to the long distance from the electron gun section to the light emitting section, changes in the electron beam traveling position,
Furthermore, it is quite difficult to make the spot diameter uniform over the entire screen. Therefore, changes in the positional accuracy of the electron beam on the phosphor and changes in spot diameter cause changes in hue, brightness, and the appearance of vertical lines, which is a major problem for text and image display devices. .

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a new flat image display device that can improve the accuracy of the traveling position of an electron beam and make the bead spot diameter uniform over the entire screen.

Means for Solving the Problems The present invention aims to improve the accuracy of the electron beam traveling position, which is the problem mentioned above, to make the electron beam spot diameter uniform, and to facilitate the processing of the modulation electrode. The electron beam generated from the electron gun is a thin line-shaped electron beam extending in the horizontal direction of the screen, and one electron beam is modulated for a plurality of picture elements between the fluorescent surface and the vertical scanning deflection electrode. Modulated electrodes 7 to -7゛ poles, the screen is Improved overall accuracy of electron beam travel position,
Furthermore, the diameter of the electron beam spot can be made uniform, and manufacturing can be facilitated by expanding the dividing pinch of the modulating electrode.

Effects of the present invention With the above configuration, the number of modulation electrodes can be reduced, and after modulating the electron beam, the electron beam can also be deflected horizontally or vertically at the same time. Since the beam position accuracy is improved and the electron beam can also be focused by these electrode parts, it is possible to make the electron beam spot diameter uniform over the entire screen. As a result, uneven brightness, uneven pitch, etc. on the light emitting surface can be eliminated.

In FIG. 1, a group of electrodes having 9 parts for each action is actually arranged in a vacuum container, but in order to make the electrode groups etc. clear, the vacuum container is replaced by vacuum envelopes 9 and 12. A part of it is illustrated. A light emitting section 1o made of a fluorescent material is provided on the vacuum side of the vacuum envelope 9 made of glass. The light emitting section 10 may be provided with a metal back layer in order to improve the luminance, or if color display is to be performed, phosphors of three colors emitting red, green, and blue may be provided in stripes at a predetermined pitch. It should be formed as follows. A vertical scanning deflection electrode 11 that is vertically divided by a predetermined pinch and elongated in the horizontal direction is provided on the vacuum side of the vacuum envelope 12, substantially parallel to the light emitting part 1o with a predetermined interval maintained therebetween. The vertical scanning deflection electrode 11 is
A thin film such as a transparent conductive film or an A1 film is formed on the surface of the vacuum envelope 120 by photoetching. The vertical scanning deflection electrode 11 usually corresponds to a horizontal scanning line, and its 1/rl
(n is an integer). Vertical scanning deflection electrode 1
1 and the light emitting section 10, a vertical scanning deflection electrode 11 is provided.
A planar shield electrode 13 with electron beam passing holes formed at a predetermined interval from the side was divided horizontally by a pinch of a predetermined 1o vane, and an electron beam passing hole was formed in each of the divided electrodes. A modulation electrode 14 and a horizontal deflection electrode 15 vertically divided into two in a comb shape are arranged.

Although not shown in the drawings, an insulating spacer or the like is inserted and integrated between the electrodes in order to maintain a constant predetermined spacing and to fix each electrode. Next, an electron source for generating a thin line-shaped electron beam in the horizontal direction of the screen is provided in the space between the light emitting part 1o and the vertical scanning deflection electrode 11 in an extension along the surface direction of the light emitting part 100. As for the structure, a linear cathode 17, which is a thin metal wire made of tungsten or the like coated with an oxide cathode, is placed under tension using a spring (not shown). A back electrode 16 is provided to direct the electron beam generated by heating the cathode 17 toward the vertical scanning deflection electrode 11 side, and an electron beam passing hole is provided in front of the linear cathode 17 facing the linear cathode 17. A G1 electrode 18 for controlling the electron beam, a G2 electrode 19 for extracting the electron beam, and a linear cathode 11 have a focusing effect and position correction for the electron beam which is divided and placed opposite to the electron beam 17. A focusing electrode 20 is provided. Although not shown, each electrode is fixed by a spacer inserted between each electrode, and each interval is kept constant.

In the above explanation, each electrode is explained to explain the basic function, and there are no particular restrictions on the location or number of electrodes, and other electrodes may be added in addition to the configuration of the example. There is no problem even if it is done.

Next, the operation of the flat panel image display device shown in FIG. 1 will be explained using FIGS. 2 to 6.

In FIG. 2, electrons generated by heating the linear cathode 17 are transmitted to the back electrode 16, the G1 electrode 18, the G
The electron beam 21 (indicated by a dotted line in the figure) is drawn out to the focusing electrode 20 side by a predetermined potential applied to the two electrodes 19, and the focusing electrode 20 focuses the electron beam 21 and at the same time The electron beam 21 is attached to each of the focusing electrodes 2o provided on both sides of the beam 21.
By applying a position correction voltage for correcting the position of the electron beam 21, the position of the electron beam 21 is also corrected. Next, the electron beam 21 travels through a space where the vertical scanning deflection electrode 11 and the shield electrode 13 face each other.

Here, when substantially the same potential is applied to the vertical scanning deflection electrode 11 and the shield electrode 13, the image electrodes 11. Alternatively, as shown in FIG. 6, voltages with different signals are applied, and the electron beam 21 is deflected toward the light emitting section. In FIG. 4, a potential (BBO) for deflecting the electron beam 21 that has traveled straight between the vertical scanning deflection electrode 11 and the shield electrode 13 toward the light emitting section 1o is constantly applied to the vertical scanning deflection electrode 11a, and the vertical scanning deflection electrode 11a A voltage applied to the shield electrode 13 and an approximately concave voltage (EBP) pulse are applied to the deflection electrode 11b for only one horizontal scanning period (1H) from the start of one field (1V) period, and the voltage applied to the vertical scanning deflection electrode 11b is applied to the deflection electrode 11b. In the 2H period, 13 pages of pulse voltage that becomes longer for each horizontal scanning period is applied to the vertical scanning deflection electrode 11c sequentially for the 3H period, and the vertical scanning deflection electrode 11c closest to the focusing electrode 20 is
A voltage of the BBP value is always applied as a direct current to 1n.

Returning to FIG. 2, the vertical scanning deflection electrode 11 shown in FIG.
By the voltage application method, the electron beam 21 that has traveled straight between the vertical scanning deflection electrode 11 and the shield electrode 13 is sequentially converted into electron beams 21 a 121 b from the vertical scanning deflection electrodes 11 a to 11 n.

21c and a scanning operation can be performed by changing the position on the light emitting section 1o. In addition, in a normal television system, it is necessary to perform an interlacing operation, but the method for doing so is to perform interlace operation for each applied voltage shown in FIG. ,
By making a slight difference in EBP or BBO, the trajectory of the electron beam can be changed to perform the above operation. Next, the operation when the number of vertical scanning deflection electrodes 11 is reduced will be explained using FIG. 5.

Normally, the same number of vertical scanning deflection electrodes 11 as the horizontal scanning lines are arranged, but this requires them to be divided quite finely, so that it may be difficult to divide the electrodes 11 into circuits, the number of terminals, etc. A problem occurs. Therefore, the number of vertical scanning deflection electrodes 11 is 1/rl (n is an integer of 2 or more) of the horizontal scanning electrodes, and by applying a pulse voltage as shown in FIG. It is possible to do this.

EBO is applied during the first horizontal scanning period (1H) of the field.
Further, in the 2nd H, a voltage (EBQ) lower than EBO is applied, and the EBO voltage is applied during the other periods. Next, a voltage of 1iBp is applied to the vertical scanning deflection electrode 11b until the first 2H, BBO is applied to the 3rd H, EBQ is applied to the 14th H, and a voltage of 1 iBp is applied to the vertical scanning deflection electrode 11C until the first 4H. BBP voltage is 6H
These pulse voltages are sequentially applied up to the vertical scanning deflection electrode 11n, such as the voltage of EBQ is applied to EBO16H. By the above method, each of the vertical scanning deflection electrodes 11 can perform the scanning operation by changing the position of the electron beam 16 in the light emitting section 10, while at the same time taking charge of the electron beam scanning for the 2H period. . As mentioned above, even if the number of vertical scanning deflection electrodes 11 is the same as the number of horizontal scanning lines or 1/rl (n is an integer of 2 or more), by changing the pulse voltage applied to the vertical scanning deflection electrode 11, it is possible to Scanning operation is possible.

Furthermore, as another method, the same effect as the above method can be obtained by changing the position correction voltage of the electron beam applied to the focusing electrode 2o.

The electron beam 21 heated by the linear cathode 17 travels between the vertical scanning deflection electrode 11 and the shield electrode 130 by the method described above. Depending on the relationship between the potentials applied to each of the vertical scanning deflection electrodes 11, the shield electrode 13

The shield electrode 13 is provided with electron beam passing holes at a predetermined pitch in the horizontal direction of the screen, and the negative electron beam passes through the electron beam passing holes of the shield electrode 13 up to the front of the shield electrode 13. This results in an electron beam that is divided at equal pitches in the horizontal direction. Next, modulation is performed on each of the horizontally divided electron beams.

Characters, images, etc. are displayed on the base unit 10. The width for horizontally deflecting each electron beam is arbitrary.
If 0 is a white/black display, simply apply a signal for each pixel to the modulation electrode 14 in synchronization for each horizontal deflection width, and image characters, etc. will be displayed horizontally on the light emitting section 1o. are connected in succession, and if the light emitting part 10 is a color display, red, green, and blue modulation signals are sent to the modulation electrode 14 for each horizontal deflection width in synchronization with each color of the light emitting part 1o. When applied, color display consisting of red, green, and blue can be performed on the light emitting section.

Next, a flat panel image display device shown in FIGS. 6 and 7 will be described as a second embodiment of the present invention.

Here, as a matter of course, a potential for deflecting the electron beam toward the light emitting section 1o is applied to each of the vertical scanning deflection electrodes 11 during a plurality of horizontal scanning periods.

There are no problems. Also,
An interlace operation may be performed using the vertical deflection electrode 22.

Although the present invention has been described above using embodiments, the horizontal deflection electrode may be removed by electrically dividing the modulation electrode for each pixel.

Furthermore, although the electron source has been described as being placed at the bottom in the screen extension direction, there is no problem if it is placed at the top in the screen extension direction. In that case, the relationship between the potentials applied to the vertical scanning deflection electrodes may be changed.
