Multi-scan-line color CRT picture tube and multi-scan-line high-resolution CRT image display device

[technical field]

The present invention relates to the structure and the application technology of a kind of multi-scan-line color CRT (Cathode Ray Tube) cathode-ray picture tube, especially a kind of application technology that adopts multi-scan-line color CRT picture tube to realize the high-definition image device shown, and the method for adjustment of a kind of multi-scan-line color CRT picture tube multigroup electron beams scanning rectification.Handle by picture signal being carried out digital technology, and the employing of multi-scan-line color CRT picture tube, make the CRT picture tube can realize large-screen, high brightness, high-contrast, high definition and performance such as ultra-thin, to adapt to the specification requirement of HDTV high definition digital television machine and high-definition image display.

[background technology]

General CRT monitor, as: CRT television set and CRT computer monitor, the CRT picture tube that uses all is to belong to single sweep line CRT picture tube at present, that is: electron gun can only be launched one group of 3 beam electrons ray of representing red (R), green (G), blue (B) three kinds of colors respectively, each under the effect of magnetic deflection field, on phosphor screen, can only scan a colour bright line (abbreviation scan line).When this single sweep line CRT picture tube is used as image display, general all is to add picture signal by the negative electrode of giving electron gun, make the electronics subject image signal modulation of cathode emission, and the line focus utmost point is focused into electron beam, electron beam quickens by high-voltage anode then, the magnetic deflection field that produces through deflecting coil is carried out synchronous deflection again, makes electron beam scan one, one line scanning image bright line on phosphor screen and realizes that image shows.

The image display technology of this single sweep line CRT picture tube used more than 60 year, because its technology is constantly being improved, performance improves constantly, and therefore, single sweep line CRT picture tube also is being extensive use of aspect broadcast television set and computer monitor at present.And luminous, the light-emitting phosphor response speed is fast, and is bright in luster by electron gun divergent bundle impact fluorescence powder for the CRT picture tube, the contrast height, and these advantages are that other display is difficult to than reaching.But the CRT crt display unit is compared with other flat-panel monitor, and shortcoming is also arranged, and one is that the screen of display is big more, and screen luminosity and contrast are just low more, and therefore, the maximum screen size of at present general CRT crt display unit is difficult to accomplish more than 32 cun.

Along with starting broadcasting of high definition digital television program, people are to television image definition, brightness, contrast, and all have higher requirement in aspect such as large-screen.Single sweep line CRT picture tube is used for the small screen simulated television and carries out the image demonstration, and effect is very satisfactory, if but be used for large-screen receiver, or the high definition digital television machine, then image definition and brightness, and contrast, then seem seriously on the low side, be difficult to satisfactory.

For example: the HDTV high definition digital television technical standard of China, the image sampling form is 1920X1080I, if satisfy the requirement of this image display format fully, then needs the screen size of CRT high-definition television picture tube to reach more than 32 cun.But when CRT screen of TV set size during greater than 29 cun, image brightness and contrast all can occur seriously on the low side.For example, the brightness of the CRT television set of 32 cun screens generally has only about 2/3rds of 21 cun CRT television sets brightness, and its anode current is twice many than the anode current of 21 cun television sets, the anode current of 21 cun television sets is generally 0.6～0.8mA, and the anode current of 32 cun large-screen receivers is generally 1.3～1.8mA.Anode current is excessive, on the one hand, because the effect that space charge repels mutually can make display image occur defocusing, influences image definition; On the other hand, anode current is excessive, also can have a strong impact on the useful life of CRT picture tube, because anode current is excessive, can make the negative electrode of picture tube occur fatigue easily and cross presenility, therefore, will be far smaller than the small screen TV machine useful life of large-screen receiver.These shortcomings have begun to limit the sustainable development of CRT television set, make people's sight begin to transfer on one's body other flat-panel monitor.

In order to improve the definition of single sweep line CRT picture tube display image, people can do the screen of CRT picture tube greatly on the one hand, perhaps the pitch of fluorescent material dot matrix is reduced, the number of picture tube pixel is increased, but the crt screen size is big more, or the pitch of fluorescent material dot matrix is more little, and then image brightness and contrast are then low more.This is because large-screen receiver electron beam scanning linear velocity is far longer than the cause of small screen TV organic electronic bundle scan line speed, the relative time that makes electron beam act on fluorescent material shortens, and fluorescent material dot matrix pitch is more little, the area of light-emitting phosphor point is also corresponding to be reduced, and light-emitting phosphor brightness is reduced.

On the other hand,, must increase number of scanning lines in order to improve the vertical resolution of image, but the number of scanning lines increase, the line-scanning frequency of display is also wanted corresponding raising.Line-scanning frequency improves, and corresponding video bandwidth also needs to improve, otherwise the image level definition will descend.But because final video amplifier requires output voltage amplitude very high, operating voltage also needs very high, and for general CRT video amplifier circuit, this condition is very harsh, is difficult to realize.

When the CRT picture tube when image brightness and contrast all reach maximum, require the picture signal input range to reach more than 150 volts, therefore, the operating voltage of CRT video amplifier circuit is generally all chosen and is approximately 200 volts.And the output loading of CRT video amplifier circuit belongs to capacitive properties, when tube cathode over the ground distributed capacitance and after video amplifier tube collector electrode equivalent capacity over the ground determines, the key of decision video bandwidth is exactly the size of video amplifier load resistance resistance.

Fig. 1 is the video amplifier circuit that often uses in the common CRT television set, and among Fig. 1, V1 is a video amplifier tube, and C0 is a tube cathode distributed capacitance over the ground, and video amplifier tube collector electrode equivalent capacity over the ground.To video amplifier circuit video bandwidth principle Analysis, preferably, by detecting the variation of output waveform, observe the instant response of amplifier then to square wave to positive square wave of amplifier input or losing side ripple.

Tube cathode electric capacity over the ground is generally 5～10pF (relevant with picture tube model and base structure and PCB layout), and video amplifier tube collector electrode equivalent capacity over the ground is 2～10pF (relevant with transistor model and collector current).When tube cathode over the ground distributed capacitance and after video amplifier tube collector electrode equivalent capacity over the ground determines, the key of decision video bandwidth is exactly the resistance of amplifier load R1.

Fig. 2 be when input pulse signal (square wave) amplitude identical, but the pulse duration output waveform of the video amplifier simultaneously not, dotted line is represented desirable output waveform, solid line is actual output waveform.τ is a time constant among Fig. 2, τ=R1 * C0, when received image signal is pulse losing side ripple, look and put pipe and end, supply voltage Ec charges to capacitor C 0 by resistance R 1, output voltage is exactly the voltage at C0 two ends, and its charging process is pressed index law and changed, and voltage build-up rate dv/dt is similar to τ at electric capacity charging initial period and is inversely proportional to.When the time that supply voltage Ec charges by 1 pair of capacitor C of resistance R 0 was τ, the voltage at electric capacity two ends reached 63% of charging voltage Ec; The time of charging by 1 pair of capacitor C of resistance R 0 as supply voltage Ec is 2.3 ^τThe time, the voltage at electric capacity two ends is 90% of charging voltage Ec.As can be seen from Figure 2, the amplitude distortion of the more little output waveform of τ is just more little, or τ the frequency band of small video amplifier is just wide more more.And when the input pulse signal is positive square wave, look and put the pipe conducting, capacitor C 0 both end voltage is discharged to emitter over the ground by looking the collector electrode of putting pipe, because it is very little to look the internal resistance of putting the pipe conducting, therefore, to carry out discharge process over the ground to emitter fast more a lot of than charging process by looking the collector electrode of putting pipe for capacitor C 0 both end voltage.

The video amplifier is general all to define passband by the half-power point of output voltage (voltage amplitude 0.707 times), from Fig. 2, it can also be seen that, output voltage approximately needs the time of 1.2 τ from 0 half-power point that rises to voltage max, and output voltage drops at 10% o'clock by voltage max, the time that needs is less than τ, we can define the highest frequency or the high workload cut-off frequency of vision signal with 2 τ times as cycle of pulse signal thus, the cycle that is the maximum operating frequency of the video amplifier approximates 2 τ, if the back edge of the previous pulse of output signal and the forward position of a back pulse will overlap less than 2 τ in the cycle.Hence one can see that, and when the highest frequency of vision signal was higher than 1/2 τ, the amplitude of video amplifier output signal will be less than half-power point, and the front and back of two pulses be along connecting together, and promptly image definition will descend.

According to last surface analysis, the total distributed capacitance C0 that we get output circuit is 10pF, and the average voltage at load resistance R1 two ends is reduced to 75V, and the operating voltage of the video amplifier is 200V, and the cycle of getting video is 2 τ.Can obtain the resistance of the load resistance R1 that requires under the different video bandwidth thus, and average loss power:

Video bandwidth: 74MHz, R=700 Ω, resistance loss power=8W looks and puts pipe loss power=13.4W

Video bandwidth: 31MHz, R=1600 Ω, resistance loss power=3.5W looks and puts pipe loss power=5.9W

Video bandwidth: 28MHz, R=1800 Ω, resistance loss power=3.1W looks and puts pipe loss power=5.2W

This is just to one of them parameter request of No. one video amplifier wherein, for common CRT picture tube television set or image display, need 3 CRT video amplifier circuits as shown in Figure 1, the light power consumption just has tens watts, hence one can see that, and video bandwidth will reach 74MHz neither be easy to thing by part.

In order to improve the horizontal image resolution of single sweep line CRT picture tube, can do the screen of picture tube greatly, with the number of increase fluorescent material dot matrix, but because the number of vertical scan line is fixed, it can't increase because of the increase of crt screen, therefore, large-screen receiver is compared with the small screen TV machine, and vertical definition does not only increase, and increases because of television screen on the contrary, display screen vertical point reproduction of image rate descends, and makes the image displaying quality variation.Display screen dot image representation rate is defined as: the ratio of the efficient lighting area of pixel and the gross area of pixel.Obviously, dot image representation rate is a very important technical indicator for television set, and the big more television image display effect of dot image representation rate is just good more.Being that image is bright on the one hand, is the also corresponding raising of image definition on the other hand.

After the television system decision, the image definition of television set has just been decided by the parameter of picture tube and the video bandwidth of transmitted image signalling channel substantially.With China PAL/D television system is example, the image display format of pal television is: field-scanning period is 50Hz, frame frequency is 25Hz, every field scan line number is 312.5 row, the two field picture scanning group is synthesized a two field picture, every two field picture number of scanning lines is 625 row, wherein 50 row drop in the two field scan black-out intervals, the real image displaying contents is 576 row, line-scanning frequency is 15625Hz, and video bandwidth is 6MHz, and the line-scanning period is 64 microseconds, the line traversal time is about 51.5 microseconds, and the line scanning retrace interval is about 12.5 microseconds.

Hence one can see that, if picture signal is square wave or sine wave that a frequency is 6MHz, then will occur 312 chequered with black and white vertical lines on the screen.For 6MHz video bandwidth pal television machine, its horizontal definition has only 312 lines, and vertical definition is 576 lines.Such image definition is a television set below 21 cun for video screen, also satisfied at last basically, but for the television set more than 25 cun, image definition, and image brightness and contrast obviously feel all not high enough.With 29 cun CRT TVs is example, and the screen area of 29 cun CRT picture tubes is approximately: 590 * 440 (long * wide) square millimeter, the general fluorescent material equalization point of common picture tube is apart from being approximately 0.65 millimeter (on 0.6 limit, center 0.7).

According to the data of last surface analysis, we can be 908 lines in the hope of the horizontal resolution of common 29 cun CRT picture tubes, and vertical resolution is exactly the number of scanning lines of a two field picture, i.e. 576 lines.If vertical resolution is converted to the pitch of luminous point, it is exactly 0.76 millimeter.As seen the vertical resolution of 29 cun CRT picture tubes is more much lower than horizontal resolution.The fluorescent material dot matrix of chromoscope generally all is made up of black, red, blue, green four kinds of colors, and wherein black is graphite, and the black color of representative to strengthen picture contrast, is used for conduction on the other hand on the one hand, is used for eliminating the static on the fluorescent material.Hence one can see that, and level point reproduction of image rate is 3/4ths, and vertical point reproduction of image rate will increase and diminish along with screen, because the number of the thickness of scan line and scan line fixes substantially, but pitch can increase and increase along with crt screen.

When phosphor screen complete when bright, the light-dark ratio of the pixel horizontal direction of being made up of fluorescent material is 3: 1, and the light-dark ratio of 29 cun CRT picture tube vertical direction pixels approximately has only 1: 1 (relevant with screen size), vertical dim spot area is 2.53 times of horizontal dim spot area, and vertical pixel point area only is 0.84 times of horizontal pixel point area.If we are defined as the light-dark ratio of pixel the light-emitting area utilance of pixel, or luminous efficiency, then the light-dark ratio of pixel is big more, the luminous efficiency of pixels illustrated point is just high more, and dot image representation rate is big more, and image display effect is just good more, when the dot image representation rate of vertical and level is 100%, we just can declare, such image shows and to be only " flawless ", and this also is that people are always in the effect of piece piece wanting unfailingly to pursue.

Hence one can see that, the utilance of 29 cun CRT picture tube horizontal direction pixel light-emitting areas is 3 times of utilance of vertical direction pixel light-emitting area, conversely, vertical dim spot area is 2.53 times of horizontal dim spot area, and this explanation large-screen CRT picture tube vertical direction image display effect is more far short of what is expected than horizontal direction image display effect.The area of CRT crt screen is big more, and the image display effect of vertical direction is just bigger more than the effect difference that horizontal direction image shows, we can the demonstration of Direct observation screen of TV set just can obtain proof for this.Common people, if do not pay special attention to, be not easy to see that scan line appears in 14 cun television sets, and the scan line of 21 cun television sets just is easy to and can sees, just see easily for 29 cun large-screen receivers, people all can see each the bar scan line on the video screen very clearly in the scope of 1.5 meters of distance video screens, this is because 29 cun lower causes of large-screen CRT television set vertical point reproduction of image rate.

Single sweep line CRT picture tube, when being used for display image, generally all be that a field picture signal is handled line by line, then by electron beam in the enterprising line scanning imaging of phosphor screen, in order to save video bandwidth, most of television sets all are to adopt the scan line of two field picture to stagger mutually, then the method for the synthetic two field picture of two field scan image sets are come picture signal is shown that this image scanning form is commonly referred to as interlacing scan.

Though interlacing scan can improve image definition in limited video bandwidth, interlacing scan also can bring new problem.When the contrast between adjacent two scan lines of two field picture signal differed greatly, the interline flicker phenomenon can appear in image, when particularly showing the rest image picture, and the easiest appearance of interline flicker phenomenon.Reason is the sweep interval of interlaced scan tv signal two adjacent lines oversize (20mS), therefore, in order to eliminate the interline flicker phenomenon, people have invented the progressive-scan tv machine again, the interlaced scan tv signal is handled by digital technology, convert progressive scanned TV signal to, but the line-scanning frequency of this progressive-scan tv machine need double, corresponding video bandwidth also needs to double.

The single sweep line CRT picture tube that general computer monitor uses, its fluorescent material dot matrix pitch is little more a lot of than the fluorescent material dot matrix pitch of the single sweep line CRT picture tube that television indicator uses, approximately has only 0.2～0.3 millimeter, therefore, its image display resolution is than higher, but computer monitor must improve line-scanning frequency in order to improve the image display resolution, and line-scanning frequency is too high, can reduce fluoroscopic luminous efficiency, the brightness and contrast of display can be reduced; In addition, in order to improve the video bandwidth of the CRT video amplifier, the operating voltage of general computer monitor final video amplifier all obtains very low, therefore, its voltage amplitude that outputs to the CRT tube cathode will be very low, the result, the image brightness and the contrast of computer monitor are reduced, fortunately computer monitor mainly is to be used for showing rest image, just do not allow the people feel that image brightness and contrast are very low, if come the show events image with computer monitor, its image display effect is with non-constant.

In addition, in order to reduce the thickness of single sweep line CRT picture tube, at present generally all be to adopt the method that increases the vertical and horizontal sweep deflection angle of electron beam, but electron beam vertically and after the increase of horizontal sweep deflection angle produces the distortion of image scanning linearity with the back, and the size that the size of picture tube edge pixel point is compared central pixel point must increase a lot, for example: light water simple scan deflection angle is 90 ° a picture tube, the pitch of its central pixel point is generally 0.5mm, the pitch of edge pixel point is generally 0.7mm, and the horizontal sweep deflection angle is 140 ° a picture tube, the pitch of its central pixel point is generally 0.6mm, the pitch of edge pixel point is generally 1.0mm, that is: the horizontal resolution of picture tube is along with the increase of deflection angle will significantly descend.

In order to overcome the shortcoming of above-mentioned single sweep line CRT picture tube, multi-scan-line color CRT picture tube of the present invention, adopt multigroup electron beams simultaneously phosphor screen to be scanned (composite type scanning), and all right subarea-scanning (Distributed Scans) of multigroup electron beams, image brightness is significantly improved, the thickness of CRT picture tube is reduced, and the also corresponding raising of image display resolution; On the other hand, handle by picture signal being carried out digital technology, the serialization graph image signal is changed into parallel signal output, can make the corresponding reduction of line-scanning frequency of display like this, thereby image brightness and contrast and image definition are improved greatly, simultaneously, the frequency bandwidth to the vision signal amplifying circuit requires also can reduce widely.

In addition, multi-scan-line color CRT picture tube is aspect the image demonstration, and having many good qualities also is that LCD, PDP flat-panel monitor are incomparable, and one of them is that the image brightness response speed is fast, and the show events image can not trail; Next is to carry out the conversion of image display format easily, and image display format conversion quantization noise is little, and image fault is also very little.

And the shortcoming of dull and stereotyped digital display maximums such as LCD, PDP, be exactly, when image sampling dot matrix format and image show that dot matrix format is inequality, carry out the conversion of image display format although method such as can add some points or subtract a little, but when the image sampling dot matrix did not become corresponding relation with the position of pixels of display screen, image shows can produce quantization noise or image fault.During image fault, be not image the part picture is cut vertically, be exactly that image the right and left picture is cut, or blacking.

The analog image display is when carrying out the display format conversion, can be by any proportional zoom, but the position that does not need each image sampling is selected is corresponding one by one with the position of image on fluorescent screen vegetarian refreshments, because what export to after D/A conversion that the CRT picture tube shows is to change continuous analog picture signal, at last, the shadow mask net or the phosphor pixel point that are equivalent to the CRT picture tube are taken a sample to analog signal once more, therefore, as long as the number of CRT picture tube phosphor pixel point is greater than the number of input digital image sample of signal point, the image display resolution just remains unchanged substantially.

Therefore, multi-scan-line color CRT picture tube and single sweep line color CRT picture tube or LCD, PDP flat-panel monitor are compared, and its image displaying quality and performance can improve greatly.This high performance multi-scan-line color CRT picture tube replaces present single sweep line color CRT picture tube, will be used widely aspect large-screen HDTV digital TV in high resolution machine and the large-screen high-clear display.

Therefore according to the HDTV high definition digital television technical standard of China, the image sampling form is 1920X1080I, approximately needs the video bandwidth of 74MHz could satisfy the requirement of 1920X1080I high-definition image display format fully.For requiring the output image signal amplitude to reach 150 volts of above CRT video amplifier circuits, be to be difficult to satisfy so high video bandwidth, in order to reduce the video bandwidth of the CRT video amplifier, and don't the definition of reduction TV images, a best way reduces the television set line-scanning frequency exactly.Reduce the operating frequency of television set line scanning, not only can reduce the video bandwidth of the CRT video amplifier, the brightness and contrast that can also improve television set simultaneously, the operating frequency of line scanning reduces by one times, being equivalent to the brightness and contrast doubles, in addition, can also reduce line scanning output power.

China's HDTV high definition digital television airport scanning frequency is 50Hz, line-scanning frequency is 28.125KHz, the horizontal scanning line number is 1125, line-scanning period 35.56uS, the line traversal time is 25.86uS, the line scanning retrace interval is 9.7uS, and two field picture is shown as 1080 lines, and field picture is shown as 540 lines.If adopt dual scanning line to show, every of every group of electron beam trace on the scene scan period only needs scanning 270 lines, is equivalent to line-scanning frequency and can reduces half, and promptly line-scanning frequency can be reduced to 14.06KHz.

Except reducing the video bandwidth of the CRT video amplifier with the method that reduces line-scanning frequency, can also select for use horizontal distribution formula multi-scan-line color CRT picture tube or mixed distribution formula multi-scan-line color CRT picture tube to show, can reduce the video bandwidth of the CRT video amplifier equally as image.Select for use horizontal distribution formula dual scanning line color CRT picture tube to show that as image the video bandwidth of the CRT video amplifier can reduce half; Select for use horizontal distribution formula three scan line color CRT picture tube to show as image, the video bandwidth of the CRT video amplifier can be reduced to has only one of original three parts; Perhaps under the constant situation of video bandwidth, can improve many times of image definitions.

The great advantage of horizontal distribution formula multi-scan-line color CRT picture tube or mixed distribution formula multi-scan-line color CRT picture tube television set or display is thin, next is the definition height of picture tube, having the image brightness of being exactly and contrast very high again, is exactly that the display image scanner distortion is little in addition.

Common CRT television set is thin more, the angle of requirement CRT picture tube beam scan deflection will be big more, the angle of picture tube beam scan deflection is big more, picture tube center electron beam scan deflection unit angle projects to the distance on the phosphor screen, the distance that projects on the phosphor screen with picture tube edge electron beam scanning deflection unit angle differs just big more, when the angle of picture tube beam scan deflection during greater than 90 °, the projector distance of electron beam in the projector distance of center unit's angle and electron beam in edge unit's angle differs and reaches more than the twice.

Its result, one is that display image can produce scanner distortion, another is that the spacing of picture tube edge pixel point is more a lot of than increasing with respect to the spacing of picture tube central pixel point.Because pass the incidence angle of shadow mask net when electron beam big more, its energy loss will be big more, therefore, must increase the window area of picture tube edge shadow mask net, could guarantee that the energy of electron beam is not suffered a loss.So the spacing of common large-screen CRT picture tube edge image on fluorescent screen vegetarian refreshments will be twice than the spacing of center image on fluorescent screen vegetarian refreshments, the unevenness that could guarantee picture tube brightness is less than 20%.

Large-screen horizontal distribution formula multi-scan-line color CRT picture tube is compared with measure-alike common large-screen CRT picture tube, the angle of its electron beam scanning deflection is much smaller, therefore, the spacing of the spacing of picture tube edge image on fluorescent screen vegetarian refreshments and picture tube center image on fluorescent screen vegetarian refreshments, differing just can not be very big, so the image display resolution of horizontal distribution formula dual scanning line color CRT picture tube can improve relatively.

From the principle, the angle of CRT picture tube beam horizontal sweep deflection should be less than the angle of vertical scanning deflection, it is relative the highest that its image display resolution just can reach, because the window of shadow mask net is vertical strip basically in the CRT picture tube, and arrange in turn by horizontal direction, the width of window is exactly the minimum pitch of horizontal pixel point, and the size of vertical pixel point mainly to be the thickness that relies on scan line distinguish, that is: the pitch of vertical pixel point is far smaller than the minimum pitch of horizontal pixel point.For 16: 9 high definition digital television machines, if select for use horizontal distribution formula dual scanning line color CRT picture tube as display, two electron gun horizontal sweep width are 8: 9 with the ratio of vertical scanning width, that is: horizontal width is less than vertical width, therefore, its image display resolution is a lot of with respect to the confidential height of 16: 9 color CRT picture tubes of single sweep line high definition digital television.

Show as horizontal distribution formula three scan line color CRT picture tube being used for 16: 9 images, electron beam horizontal deflection angle is 5.3: 9 with the ratio at vertical deflection angle, therefore, it can do very highly aspect horizontal definition, such as: the pixel pitch can be reduced to below the 0.4mm, and the pitch of center and edge pixel point is identical, its edge brightness can be less than 80% with the center brightness ratio yet, and for common 16: 9 large-screen CRT picture tubes, if the minimum value of central pixel point pitch is 0.4mm, then the pitch of edge pixel point may need to reach more than 0.8 and just can meet the demands, and therefore the mean pitch of common CRT picture tube pixel generally can be less than 0.6mm.With 36 cun 16: 9 large-screen CRT picture tubes is example, if the mean pitch of pixel is 0.6mm, then the total pixel number of horizontal direction is 1354, and this numerical value also has very big distance from 1920; If select horizontal distribution formula three scan line color CRT picture tube for use, the mean pitch of pixel is 0.4mm, and then the total pixel number of horizontal direction is 2032, and this numerical value can satisfy the requirement of high definition digital television studio resolution standard fully.

Horizontal distribution formula dual scanning line color CRT picture tube television set or display, delegation's picture signal is divided into two hemistich picture signals and line output, be equivalent to bit rate output and reduced half, that is: the frequency of outputting video signal has also reduced half, the frequency bandwidth of the video amplifier can reduce like this, perhaps under the situation that keeps former video bandwidth, can in former data image signal, add some points, that is: between two sampling points, assign one or more new pixel picture signals again, the new pixel picture signal that produces have with former capable picture signal before, the relevant information of back two pixel picture signals is equivalent to the image level definition like this and is doubled or many times.

Point out in passing, though the numeral row picture signal bit rate output of horizontal distribution formula dual scanning line color CRT picture tube television set or display has reduced half than the code check of input signal, or the frequency of video amplifier outputting video signal can reduce half, but line-scanning frequency can not reduce, because, horizontal distribution formula dual scanning line color CRT picture tube television set can not look like composite type dual scanning line color CRT picture tube television set or display, or vertical distribution formula dual scanning line color CRT picture tube television set or display are such, can handle two row input signals simultaneously.

As it is more superior as the image display performance to select for use horizontal distribution formula three scan line color CRT picture tube to be used for the high definition digital television machine, not only image definition is high more a lot of than the image definition of 16: 9 color CRT picture tubes of single sweep line high definition digital television machine, image definition than horizontal distribution formula dual scanning line color CRT picture tube high definition digital television machine is also high, and aspect thickness, if the maximum deflection angle of horizontal distribution formula three scan line color CRT picture tube and common CRT picture tube beam is 90 °, then the thickness of 36 cun 16: 9 horizontal distribution formula three scan line color CRT picture tubes is thinner 2/5ths than common 36 cun 16: 9 large-screen CRT picture tubes, is equivalent to about thin 18cm (7 inches).

Mixed distribution formula multi-scan-line color CRT picture tube generally all has 4 more than the electron gun, and its image definition and image brightness and contrast are all very high, is specially adapted to the public arena large-screen image and shows.

Multi-scan-line color CRT picture tube multigroup electron beams is assembled and the adjustment of multi-scan-line spacing also is a key technology, and the present invention has used a large amount of lengths to be illustrated to this key technology.

Introduce the execution mode of a plurality of use multi-scan-line color CRT picture tubes below in detail as image display.

[execution mode 1] dual scanning line color CRT picture tube copy type times line scan television machine or display

Logical single sweep line CRT picture tube color television set of a Daepori as shown in Figure 4 or display, only need the single sweep line CRT picture tube that uses among Fig. 4 is changed into as Fig. 5 or composite type dual scanning line color CRT picture tube or common cathode composite type dual scanning line color CRT picture tube shown in Figure 6, just can become a new copy type times line scan television machine or display.

Figure 17 is the fundamental diagram of dual scanning line color CRT picture tube copy type times line scan television machine or display, 17100 is the scan mode of composite type dual scanning line color CRT picture tube or common cathode composite type dual scanning line color CRT picture tube and composite type bielectron rifle among the figure, picture signal row sequence " 1,2,3 ... " with " row picture signal 1, the row picture signal 2, the row picture signal 3 ... " corresponding one by one.

Its operation principle is, two groups of electron beam A and B that every capable picture signal is fed to the emission of dual scanning line electron gun simultaneously scan demonstration, make corresponding two picture lines of delegation's picture signal.Therefore, the horizontal scanning line number of this dual scanning line color CRT picture tube copy type times line scan television machine or every of display or every frame is the twice of the horizontal scanning line number of general television set or every of display or every frame.Therefore, this dual scanning line color CRT picture tube copy type times line scan television machine or display, image is vertically clear to double than common single sweep line CRT picture tube color television set or display, and image brightness and contrast also double than common CRT picture tube color television set or display.Because when this copy type times line scan television machine or display scan at every turn, two horizontal scanning lines show delegation's picture signal simultaneously, wherein delegation's picture signal just as if by copy come the same, so we call copy type times line scan television machine or display to this dual scanning line television set or display.

With the Phase Alternation Line system is example, among Figure 17, when delegation's image video signal input, two scan lines can occur on the television screen, and the original like this television set that has only 576 scan lines in Fig. 4 has but become 1152 scan lines in Figure 17.Owing to scan demonstration by the two groups of electron beam A and the B of the emission of dual scanning line electron gun simultaneously with delegation's picture signal among Figure 17, therefore, preferably select for use common cathode composite type dual scanning line color CRT picture tube as shown in Figure 6 to show as copy type times line scanning picture screen.

Dual scanning line color CRT picture tube copy type times line scan television machine or display, though horizontal scanning line quantity has been Duoed one times than single electronic beam scanning colour CRT picture tube television set or display, but line-scanning frequency does not improve, therefore, video bandwidth does not need to improve yet, horizontal definition is constant substantially, but image brightness and contrast be doubled, and vertical point reproduction of image rate and definition also are doubled.This be because, the dual scanning line image shows than single sweep line image and shows, the ratio of vertical dim spot area and horizontal dim spot area is reduced to 1.27 times by 2.53 times, is equivalent to vertical point reproduction of image rate and is doubled.

In addition, because two row picture signal correlations are very strong, therefore recycling delegation picture signal is carried out the image demonstration between two row picture signals, its effect is equivalent to make the image vertical definition to be doubled, and people generally are difficult to see and draw weak point, have only when two row picture signals differ bigger, when promptly the movement velocity of live image is very high, just can see the small stair phenomenon between two horizontal scanning lines of live image correspondence.

The operation principle of the operation principle of multi-scan-line color CRT picture tube copy type times line scan television machine or display and dual scanning line color CRT picture tube copy type times line scan television machine or display is basic identical, the multi-scan-line color CRT picture tube that multi-scan-line color CRT picture tube copy type times line scan television machine or display use, it can be a composite type multi-scan-line color CRT picture tube, it also can be a common cathode composite type multi-scan-line color CRT picture tube, when this multi-scan-line color CRT picture tube copy type times line scan television machine or display show picture signal, the n group electron beam that every capable picture signal is fed to the emission of n scan line electron gun simultaneously scans demonstration, every capable corresponding n bar scan line of picture signal while is shown, this n scan-line color CRT picture tube copy type times line scan television machine or display, the horizontal scanning line number of every or every frame be general television set or every of display or every frame the horizontal scanning line number n doubly.

[execution mode 2] dual scanning line color CRT picture tube is inserted line times line scan television machine or display

The phenomenon that occurs small stair when overcoming copy type times line scan television machine or display show events image easily, Figure 18 is the fundamental diagram that a kind of composite type dual scanning line color CRT picture tube of the present invention is inserted line times line scan television machine or display, 18100 is the scan mode of composite type dual scanning line color CRT picture tube and composite type bielectron rifle among the figure, scan line P is an original image signal scanning display line, scan line I is new slotting capable picture signal scanning display line, picture signal row sequence " 1; 2; 3; ... " with " row picture signal 1; row picture signal 2; row picture signal 3; ... " corresponding one by one.Among Figure 18,18200 is picture signal digital technology treatment circuit, comprising the capable picture signal memory that can store the above picture signal of two row, 18220 is a capable picture signal memory and the digital processing circuits that can store the above picture signal of two row, the 18240th, and the digital video signal coding circuit.

When input signal is analog picture signal, in the picture signal digital technology treatment circuit 18200 18210 at first carries out the A/D analog/digital conversion to analog picture signal to be handled, analog picture signal is converted to data image signal, then data image signal is stored among the capable picture signal memory 18220, when input signal is data image signal, then data image signal can directly be stored among the capable picture signal memory 18220, perhaps data image signal has been stored among the capable picture signal memory 18220, then, picture signal digital technology treatment circuit 18200 will be to data image signal two row of storing in the row picture signal memory, two handle capablely, that is: for the first time first row and the second row picture signal are carried out Digital Signal Processing, again second row and the third line picture signal are carried out Digital Signal Processing for the second time, other by that analogy.

The method of picture signal being carried out Digital Signal Processing is, utilize the correlation of two row picture signals to come moving picture signal is carried out prediction processing, produce the new slotting capable picture signal of delegation again, the new slotting capable picture signal that produces has the relevant information with former forward and backward two row picture signals, and the line number word image signal of handling through digital technology is stored among the capable picture signal memory 18220 once more.

Then, digital video signal coding circuit 18240 in the picture signal digital technology treatment circuit 18200 also will be to the data image signal in the row picture signal memory 18220, two row, encode again in two row ground, and with certain speed output, carry out D/A digital-to-analog conversion process through 18250 again, just can obtain the identical analog picture signal of two start of line phase places (wherein delegation inserts the row picture signal), last two row picture signals are fed to composite type dual scanning line color CRT picture tube 18100 simultaneously and show, can obtain the television image that a width of cloth is inserted line times line scanning.Because the new slotting capable picture signal that produces has the relevant information with former forward and backward two row picture signals, therefore, the image display effect of slotting line times line scan television machine or display is more clear and true to nature than the image display effect of copy type times line scan television machine or display.

The horizontal scanning line number that dual scanning line color CRT picture tube is inserted line times line scan television machine or display is the twice of common CRT picture tube television set or display horizontal scanning line number

Figure 18 18100 in scan line P be that former capable picture signal scanning shows, scan line I is that new slotting capable picture signal scanning shows (that is: inserting the capable picture signal that the new process digital technology of delegation is handled again between two row original image signals), total like this horizontal scanning line number has been Duoed one times than the horizontal scanning line number of original image signal, that is: the horizontal scanning line number of slotting line times line scan television machine of dual scanning line color CRT picture tube or display is the twice of common CRT picture tube television set or display horizontal scanning line number.Therefore, the image brightness that dual scanning line color CRT picture tube is inserted line times line scan television machine or display doubles than the image brightness of common CRT picture tube television set or display figure, but line-scanning frequency does not change.

Low line frequency interlaced scan tv machine of [execution mode 3] dual scanning line color CRT picture tube or display

Figure 19 is the fundamental diagram of low line frequency interlaced scan tv machine of a kind of dual scanning line color CRT picture tube of the present invention or display, among Figure 19,19100 is the scan mode of composite type dual scanning line color CRT picture tube and composite type bielectron rifle, picture signal row sequence " 1,2,3 ... " with " row picture signal 1, the row picture signal 2, the row picture signal 3 ... " corresponding one by one.Among Figure 19,19200 is picture signal digital technology treatment circuit, comprising the capable picture signal memory that can store the above picture signal of two row, 19220 is a capable picture signal memory and the digital processing circuits that can store the above picture signal of two row, the 19240th, and the digital video signal coding circuit.

When input signal is analog picture signal, in the picture signal digital technology treatment circuit 19200 19210 at first carries out the A/D analog/digital conversion to analog picture signal to be handled, analog picture signal is converted to data image signal, then data image signal is stored among the capable picture signal memory 19220, when input signal is data image signal, then data image signal can directly be stored among the capable picture signal memory 19220, and perhaps data image signal has been stored among the capable picture signal memory 19220.

In order to eliminate interlaced scan tv machine interline flicker phenomenon, the method that can handle with digital technology becomes the image signal transformation of interlaced scan tv the picture signal of progressive-scan tv.Principle is, earlier a field picture signal is got off by the row sequential storage, then, when waiting next field picture signal to arrive, the picture signal of storing in the field memory and next field picture signal are given dual scanning line color CRT picture tube simultaneously and are carried out the image demonstration, that is: the A group electron beam that is sent in the composite type dual scanning line color CRT picture tube of previous field picture signal scans demonstration, and the B group electron beam that next field picture signal is sent in the composite type dual scanning line color CRT picture tube scans demonstration.Because the picture signal of an original field-scanning period has at interval become output simultaneously now with current picture signal two adjacent lines picture signals, shows together, therefore, can eliminate interlaced scan tv machine interline flicker phenomenon fully.

Figure 20 is a kind of dual scanning line color CRT picture tube rolling type progressive-scan tv machine of the present invention or display fundamental diagram, among Figure 20,20100 is the scan mode of composite type dual scanning line color CRT picture tube and composite type bielectron rifle, picture signal row sequence " 1,2,3 ... " with " row picture signal 1, the row picture signal 2, the row picture signal 3 ... " corresponding one by one.Among Figure 20,20200 is picture signal digital technology treatment circuit, can store the field picture signal storage of an above picture signal and the capable picture signal memory of an above picture signal of energy storing one row comprising one, 20220 is a field picture signal storage and the digital processing circuits that can store an above picture signal, 20230 is capable picture signal memory and digital processing circuits of an above picture signal of energy storing one row, the 20240th, and the digital video signal coding circuit.

When input signal is analog picture signal, in the picture signal digital technology treatment circuit 20200 20210 at first carries out the A/D analog/digital conversion to analog picture signal to be handled, analog picture signal is converted to data image signal, then the last field picture signal in the interlaced scan tv picture signal by the row picture signal sequential storage among field picture signal storage 20220, the first few lines picture signal of next field picture signal then is stored among the capable picture signal memory 20230.

When a last field picture signal is stored, and next field picture signal is when just having begun to occur, the data image signal of storage in the field picture signal storage 20220, data image signal with storage in the row picture signal memory 20230, begin simultaneously by the output that puts in order of original image signal, at first to encode again before the data image signal output through the digital video signal coding circuit 20240 in the picture signal digital technology treatment circuit 20200, and then carry out D/A digital-to-analog conversion by 20250, at last in the output simultaneously, following two field stimulation picture signals are given composite type dual scanning line color CRT picture tube 20100 simultaneously and are carried out the image demonstration, can obtain the television image that a width of cloth rolling type is lined by line scan.

Here, the effect of field picture signal storage 20220 is the equal of that the last field picture signal in the interlaced scan tv picture signal is carried out buffer memory and delayed time a field-scanning period, the effect of row picture signal memory 20230 is the equal of that the first few lines picture signal of next field picture signal is carried out buffer memory, but the data of storing in the data of storage and the row picture signal memory 20230 in the field picture signal storage 20220 are all rolled, that is: there are data to deposit on one side, data output is arranged again on one side, therefore, on, following two field picture signal is a relative concept for picture signal memory 20220 and 20230.When only detecting the field sync signal arrival, could correctly know the beginning or the end of a field picture signal.

The capacity of row picture signal memory 20230 is generally very little, only needs the data of storing one row or several capable picture signals to get final product, and the main application of row picture signal memory 20230 is in order to guarantee two capable picture signal output strict synchronism.If last capable picture signal output can with next row picture signal output phase strict synchronism, so, do not need row picture signal memory 20230 to be fine yet.The data that need several capable picture signals of storage as for row picture signal memory 20230, mainly see ability and speed that digital circuit is handled data, if the digital circuit processing speed is slow, can store several capable picture signals, to guarantee that reserving time enough wait digital circuit carries out data processing more.

Because this dual scanning line color CRT picture tube rolling type progressive-scan tv machine or the every capable picture signal of display all are utilized twice, therefore, the field scan line also is equivalent to many one times, that is: field scan line and frame scan line quantity are identical, the difference of dual scanning line color CRT picture tube progressive-scan tv machine or display and present widely used progressive-scan tv machine or display maximum is: the line-scanning frequency of present widely used progressive-scan tv machine or display doubles than the line-scanning frequency of interlaced scan tv machine or display, and the line-scanning frequency of the line-scanning frequency of dual scanning line color CRT picture tube rolling type progressive-scan tv machine or display and interlaced scan tv machine or display is basic identical.

With the PAL progressive-scan tv is example, common progressive-scan tv machine (being single sweep line CRT picture tube progressive-scan tv), field-scanning period is identical with frame frequency, be 50Hz, and line-scanning frequency needs to double, and is 31250Hz, and the line-scanning period is 32 microseconds, the scan(ing) stroke time is about 26 microseconds, and the raster flyback time is about 6 microseconds.If the image level definition still will reach the level of 312 lines, then corresponding video bandwidth need reach 12MHz.And dual scanning line progressive-scan tv machine, horizontal scanning line number and common progressive-scan tv machine are identical, all are 625 lines (display image are 576 row), but not raising of line-scanning frequency still is 15625Hz.Therefore, under same video bandwidth condition, the horizontal definition of dual scanning line progressive-scan tv machine or display doubles than the horizontal definition of common progressive-scan tv machine or display, and the brightness and contrast all doubles than common progressive-scan tv machine.

In addition, common progressive-scan tv machine is in order to become progressive scanned TV signal to the interlaced scan tv conversion of signals, need one and can store a frame image signal memory, because progressive-scan signal need reconfigure two interlaced image signals together, and become a frame by the staggered ordering of row order, export line by line by the frame image signal of rearrangement then.Because the speed of picture signal output doubles than the speed that picture signal deposits in, therefore, every capable picture signal all will perhaps be assigned the new picture signal of delegation by with twice between two original capable picture signals.And dual scanning line progressive-scan tv machine only needs the memory that can store a field picture signal, because the speed that the speed of picture signal output and picture signal deposit in is identical, but because many one group of electron beams participate in image scanning, so every capable signal also will be used twice.

Low line frequency progressive-scan tv machine of [execution mode 5] dual scanning line color CRT picture tube or display

Point out the front, the line-scanning frequency of high definition digital television machine doubles above than the line-scanning frequency of general television set, so, require the frequency band of the video amplifier quite wide, and image brightness and contrast can be on the low side, because final video amplifier requires output voltage amplitude very high, operating voltage also needs very high, for general CRT video amplifier circuit, this condition is very harsh, is difficult to realize.In order to reduce the video bandwidth of the CRT video amplifier, and don't reduce the definition of TV images, a best way is exactly the operating frequency that reduces the television set line scanning.

The method of adjustment that the scanning of [execution mode 11] multi-scan-line color CRT picture tube multigroup electron beams is corrected

Multi-scan-line color CRT picture tube, inside are equipped with multigroup electron beams ray emission device, are used for image and show that multigroup electron beams scans simultaneously, have only respectively organize electron beam can be in full accord during co-ordination, display image just distortion can not occur.

For composite type multi-scan-line color CRT picture tube, the interval between every group of electron beam scanning line must be consistent with the ratio of field scan step-length in strictness.For example: when composite type dual scanning line color CRT picture tube shown in Figure 12 was used for progressive scanning picture and shows, the interval between every group of electron beam scanning line must be one of two parts of field scan step-length, and the image of demonstration just can not produce distortion; And for example: Figure 12 a and Figure 12 b represent that respectively composite type dual scanning line color CRT picture tube is used for interlacing scan and adopts by the group interlaced image and show and interlacing scan when showing by the line interlaced image, interval between every group of electron beam scanning line must be one of four parts of field scan step-length and one of two parts, and the image of demonstration just can not produce distortion.

For distributed multi-scan-line color CRT picture tube, equally also require every scan line that each electron gun produces all to want strict alignment in direction such as upper and lower or left and right, the joint is heavy folds mutually, and the length unanimity, and the image of demonstration just can not produce distortion.

In order to guarantee the ratio strict conformance at the interval between the multi-strip scanning line and field scan step-length in the multi-scan-line color CRT picture tube, and every scan line all wants strict alignment in direction such as upper and lower or left and right, and the joint is heavy folded mutually, and the length unanimity.Multi-scan-line color CRT picture tube of the present invention in the inside of its caliber, is equipped with a soft magnetism ring between deflecting coil and multi-scan-line electron gun, and around the outer tube diameter of soft magnetism ring correspondence 12 magnet exciting coils is installed.12 magnet exciting coils are divided into two groups, wherein 8 magnet exciting coils are one group and are installed in nexine, be used for multigroup electron beams scanning rectification is finely tuned, other 4 magnet exciting coils are one group and are installed in skin, are used for multigroup electron beams scanning rectification is dynamically adjusted.8 magnet exciting coils of nexine generally all are with magnetic core, but outer field 4 magnet exciting coils can be with also band magnetic core not of magnetic core.

Install the magnet ring of magnetic pole more than in the caliber inside of picture tube, when electron beam passed from magnet ring is middle, owing to be subjected to the effect of long-range navigation thatch power, electron beam will change travel direction.Figure 27 corrects the schematic diagram of adjustment with magnet exciting coil to multigroup electron beams in the multi-scan-line color CRT picture tube.Flow through the size of current and the direction of 8 little magnet exciting coils by adjustment, just can change the magnetic field intensity of picture tube caliber inside and the distribution of the magnetic line of force, electron beam just changes the direction of motion under the effect of long-range navigation thatch power.Because each group electron beam is positioned at the position difference on the caliber cross section, its result who produced by the effect of long-range navigation thatch power is also different, therefore, always can flow through the size of current and the sense of current of 8 little magnet exciting coils, make and respectively organize beam pulling to needed position by adjustment.

From the principle, the number of magnet exciting coil is many more, and debug results is just meticulous more, but that the number of magnet exciting coil is structurally installed too much is also very difficult.Therefore,, among Figure 27 12 magnet exciting coils are divided into two groups, 8 of nexine, outer field 4 in order to install and to debug conveniently.4 big magnet exciting coils and 8 little magnet exciting coils do not have much differences substantially on operation principle, just can be slightly different when concrete the application.
