Description

The utility model relates to gas discharge technology and can be used to develop means of displaying information on color gas discharge indicator panels (GUI) of alternating current planar design.

The planar design is the most promising among the color GUIs of alternating current, since it solved the problem of degradation of the brightness of the phosphor. In this regard, it is the planar design that has received the most widespread industrial application.

Known ACI AC, comprising a first dielectric plate with pairs of parallel dielectric coated indication electrodes located on its inner surface, a second dielectric plate, on the inner surface of which control electrodes coated with a phosphor and forming display elements forming dielectric electrodes, dielectric barriers are placed orthogonally to the indication electrodes located at least on one of the dielectric plates (RF Patent No. 2089964, CL H01 J 17/49, publ. 09/10/1997).

The disadvantage of this design is the low reliability of control due to the high level of control voltages due to large losses of charged particles on the walls of dielectric barriers.

An alternating current GUI is also known, comprising a first dielectric plate with pairs of parallel dielectric coated indication electrodes located on its inner surface, and a second dielectric plate, on the inner surface of which control electrodes coated with a phosphor and forming display elements with dielectric electrodes are placed orthogonal to the indication electrodes barriers located at least on one of the dielectric plates, while optimized, the ratio the geometric dimensions of the components of the display elements, defining the conditions of recording / quenching of discharges in the ISU of alternating current (RF patent No. 2129317, class. H01 J 17/49, publ. 04/20/1999).

The disadvantage of this design is that the above ratio does not allow the most complete optimization of the geometric dimensions of the components of the display elements, since they do not reflect the working conditions of the display elements in the display mode, which leads to a decrease in the durability and reliability of the GUI.

Closest to the proposed design of the ACI ACI is the ACI ACI, comprising a first dielectric plate with pairs of parallel indication electrodes coated on the inner surface thereof and a second dielectric plate, on the inner surface of which control electrodes coated with a phosphor are placed orthogonally to the indication electrodes with indication electrodes display elements, dielectric barriers located at least on one of the electrical plates, while optimizing the thickness of the dielectric layer covering the display electrodes (RF patent No. 138736, class H01 J 17/49, publ. March 20, 2014 - prototype).

. The disadvantage of this design is that the thickness of the dielectric on the display electrodes does not fully provide the necessary operating conditions for the display elements in the display mode, since it does not take into account the ratio of the geometric dimensions of the display electrodes and their relative position, which leads to a decrease in the brightness and reliability of the GUI control.

The objective of the utility model is to create a color GUI of alternating current with high brightness and reliability of control by choosing the optimal ratio of step L of the display electrodes and their width S.

The specified technical result in the implementation of the utility model is achieved by the fact that in the known GUI of alternating current containing the first dielectric plate with pairs of parallel indication electrodes located on its inner surface and coated with a dielectric, a second dielectric plate, on the inner surface of which control electrodes are placed orthogonally to the indication electrodes, luminophore coated and forming with display electrodes display elements, dielectric barriers located at At least on one of the dielectric plates, the width S of the indication electrodes and the step L of their location are related by the ratio 2.3 <L / S <6, 5.

When this ratio is fulfilled, optimal working conditions of the display elements in the display mode are achieved, which ensures high brightness and reliability of control of the color GUI of alternating current.

The analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed utility model, allowed to establish that the applicant did not find an analogue characterized by features identical to those of the claimed utility model, and the definition from the list identified analogues of the prototype, as the closest in the totality of the characteristics of the analogue, allowed to identify the set of essential in relation to the seen it technical result distinguishing features in the claimed subject matter set forth in the claims of the utility model. Therefore, the claimed utility model meets the requirement of "novelty."

The proposed design of the ISU AC is illustrated by the drawing (Fig. 1).

The design comprises a first dielectric plate 1 on which control electrodes 2 with a phosphor coating 3 are located, dielectric barriers 4 separating the display elements, a dielectric layer 5 covering the indication electrodes 6 having a width S and an arrangement pitch L formed on the second dielectric plate 7.

The ACI GUI works as follows. A reference voltage is applied to all display electrodes that does not change the state of the display elements. For selective ignition of the display elements, it is necessary to apply a part of the write voltage to the selected control electrodes, and another part to the selected indication electrodes. At the points of intersection of the selected control electrodes and indication electrodes, a discharge is excited, which is then picked up by subsequent pulses of the reference indication voltage. To change the information on the electrodes, it is necessary to apply blanking pulses and then repeat the “write” cycle again.

Fulfillment of the proposed GUI of alternating current conditions 2,3≤L / S≤6, 5 allows you to form the optimal level of parameters of the indicator gap, providing high brightness and reliability control. A specific function of the display electrodes in the planar design of the ACI GUI is that the operator observes the glow in the display elements through the gap between the display electrodes in pairs formed on the front plate. That is, the narrower the display electrodes and the larger their pitch, the more the luminous flux reaches the operator. At the same time, with an increase in the gap between the electrodes, the electrical parameters of the indicator gap increase.

At L / S≥6.5, when the indication electrodes are narrow and their pitch is large, the electrical characteristics of the indicator gap (U z.ind. , U g.ind .) Increase significantly , since the distance between the indication electrodes increases. In addition, in the manufacture of narrow indication electrodes, a number of technological problems arise related to breaks, electrical resistance, and the complexity of manufacturing narrow electrodes.

When L / S≤2.3, i.e. when the display electrodes are wide, and the small step reduces the luminous flux (overall brightness), since the wide electrodes overlap part of the phosphor luminescence, and the memory range of the indicator gap also decreases (ΔU p. = U l.ind.- ΔU horizontal. ), which reduces the reliability of the management of the ISU.

The optimal level of the parameters of the display elements is provided when the expression 2,3≤L / S≤6, 5.

An example of a specific implementation.

The color GUI of alternating current planar design contains two cladding glass plates. On the front glass plate, a system of indicating electrodes is formed, arranged in 0.6 mm increments, having a width of 0.2 mm, coated with a dielectric layer of low-melting glass and a layer of stabilizing material with magnesium oxide, with L / S = 3.

On the lower glass plate, a system of control electrodes 0.25 mm wide, spaced 0.35 mm apart and coated with a phosphor, is formed between which dielectric barriers are made, restricting display elements having a size in the direction of the indication electrodes 0.35 mm.

When assembling the device, the front glass plate with indication electrodes is superimposed on the lower glass plate with control electrodes so that the electrodes are mutually perpendicular. The distance between the electrodes on the first and second glass plates is 0.6 mm.

After applying a sealing joint along the device’s contour and melting it, the device is pumped out and filled with a mixture of inert gases Ne + 5% Xe at a pressure of 300 mm Hg. st.V thus produced ISU AC ΔU memory range .ind n = 50 ÷ 60 V, the voltage interval U ignition indicator zazh.ind ÷ 140 = 160 V, the control voltage U RTA ignition gap. control = 70 ÷ 80 V, the overall brightness of the ISU is 450 ÷ 550 cd / m 2 . With these parameters, the ACI GUI is reliably controlled by low-voltage microcircuits, providing high and stable brightness during operation.

Thus, the claimed technical solution allows you to create a GUI AC with high reliability management.
