Developing principle of the present utility model is as follows:

At present every images of the television picture tube of regulation is by 575 row horizontal scanning lines scan line on the spot, every row-field scanning line is a horizontal scanning line by 766 pixels, the pixel summation of then every width of cloth picture is 575 * 766=440450, pixel of the present utility model is to be made of horizontal scanning line 3 each space intersection point with field scan line 4, be that horizontal scanning line 3 is 766, the field scan line is 575, pixel number requirement up to specification, also meet the requirement of field scan 575 row, because horizontal scanning line is identical with the spacing of field scan line, so its television image is wide, height ratio is 766:575=4:3, also meets the standing order of picture tube breadth ratio.

After the vision signal of television set is passed through separated in synchronization, vibration, excitation, amplification, insert the field scan line of this developing plate and the exit of horizontal scanning line respectively, its circuit theory is similar with the LCD TV picture tube that occurs at present, because the non-content that the utility model proposes of circuit is not inquired at this.The utility model is the method work of adopting " scanning is connected ", its scanning is connected operation principle and is: from first of field scan line 4 tops, one of every from top to bottom connection, horizontal scanning line 3 is connected one time from left to right successively, finish single pass, scan line is connected 575 from top to bottom successively on the spot, then horizontal scanning line is just connected 575 times from left to right successively, finish the scanning of a width of cloth television image, for preventing the flicker on the picture, interlacing scan requirement by present television image, field scan is that branch odd line interlace and even number line scanning are finished for twice, therefore the utility model also requires circuit by interleaved principle design, i.e. field scan for the first time connects 1 from top to bottom, 3,5 ... 575 row, line scanning is connected 288 times from left to right successively; Field scan for the second time connects 2,4,6 successively ... 574 row, line scanning is connected 287 times from left to right successively, according to this constantly back and forth, finish the scanning of 25 width of cloth each second, one of 766 every connection of horizontal scanning line, its voltage all changes along with the power of TV picture signal, makes field scan line and inert gas between the horizontal scanning line intersection point send strong and weak different luminous points, constitutes complete television image.

Is 1.5mm as horizontal scanning line 3 by 766 spacings, diameter is 0.3mm, the surface has the fine copper wire or the copper alloy wire of anti-oxidation coating and makes, field scan line 4 is 1.5mm by 575 spacings, diameter is that the line of 0.4mm and the equal material of horizontal scanning line is formed, then the picture amplitude of developing plate is wide 1.5 * 765=1147.5mm, high 1.5 * 574=861mm, the width of fluid sealant be 30mm then the overall dimension of developing plate be 1207.5 * 921mm, therefore, change row, field scan line spacing separately, can change the picture amplitude of developing plate, spacing between horizontal scanning line and the field scan line also can be adjusted, V-type groove 6 on the substrate 5, its cross dimensions is top width 1.2mm, bottom width 0.4mm, dark 1.9mm, for improving the intensity of substrate 5, the back side is furnished with reinforcement, distance between the row-field scanning line is very little, therefore only need very low voltage and very weak electric current, just can make inert gas neon or other luminous inert gases between two line intersection points luminous, but consider that the resistance of lead differs very big with the line length that different intersection points place is connected, for preventing the notable difference in the upper left corner and lower right corner brightness on the developing plate that voltage drop causes, therefore the operating voltage of developing plate needs to fluctuate about 300V, on visual effect, 766 horizontal scanning lines being close to face glass 1 inboard vertical distribution can not cause watching the influence of television image, and its reason is: the scattering of (1) light in glass, weakened the sensation that human eye exists horizontal scanning line; (2) when watching large screen television, generally all more than 3 meters, the lines of the also imperceptible 0.3mm diameter of the resolution capability of human eye exist apart from the distance of screen, and it is the same that this does not influence the principle of visual effect with the existence of grid in the chromoscope yet.

In sum, the utility model is simple in structure, need not special material and special process technology manufacturing, therefore cheap, be convenient to organize large-scale production, also be convenient to popularize, from security standpoint, there is not the potential blast problem of present large-scale vacuum picture tube in it, and operating voltage is also far below the vacuum picture tube, it is a kind of foolproof developing device, on image quality, because scan line and point are mechanically fixing, when developing, just there is not scan line thickness inequality yet, defectives such as picture distorts, can intactly reappear photographic effect, complexity from required circuit, it is identical with the matrix form scanning theory of present liquid crystal flat-panel television set, just require power output to increase, therefore structure is also uncomplicated, if be designed to scan the integrated package form, the price of its separate unit television set can be within 1000 yuans, on structure, if increase the field in proportion, the quantity of horizontal scanning line can be made into high-resolution and high definition developing device, adopts for computer and high definition TV, if reduce the field in proportion, the quantity of horizontal scanning line, can be made into not high billboard of resolution requirement and graph text information developing device, change row, the spacing dimension of field scan line can obtain the TV developing plate of different size dimensions, therefore the utility model is a domestic TV, teaching, scientific research, graph text information shows that what public entertainment place etc. were desirable televises and the developing facility.
