Description

The invention relates to a technique of display systems and can be used in the design of gas discharge, electroluminescent, liquid crystal, and other types of display panels, which serve to display the information panel.

Indicator panels are known, comprising cladding dielectric plates, an excitation agent, and electrode systems, the crossing points of which form indication cells, the generation or reflection of light from which is provided by the excitation agent. As the excitation agent, electroluminors of various types, ionizing gas or liquid crystals are used.

Indicator panels are devices with two-coordinate sampling, which determines the separate control of P X fn display cells using P + f inputs, where P c fn respectively the number of columns and rows of display cells.

A large number of inputs and an equal number of terminals of the electrodes are affected by the presence in the control circuit of a corresponding number of terminal key elements.

In addition, for a gas discharge panel of a constant current, a large number of inputs aggravates air leakage through the electrode leads, which reduces the reliability of the panel and complicates the technology of its manufacture. Therefore, your main task is to reduce the number of inputs of the display panel while maintaining the total number of separately controlled display cells.,

To increase the reliability and expand the functionality of the indicator panel, each of the electrodes of one system is made common for two or more (K) adjacent columns, and the row contains two or more (K) separate electrodes of the other system.

FIG. Figures 1 and 2 show variants of post-farm current files; FIG. 3 shows the configuration of electrodes of pro-opposite systems for an alternating current panel that does not contain a dielectric grid with an orifice matrix (indication cells are conventionally shown as dashed lines, external thermal plates and internal charging glasses are not shown), alternating current panels (see Fig. 1) and 2 contain dielectric covering plates (not shown in Fig.), a dielectric plate 1 with a matrix of holes, and two systems of opposite electrodes (cathode 2 and anode 3). The excitation agent is an ionizable gas. The cathodes 2 are burned (see Fig. 1) ow Each of the rows of holes contains three separate anode electrodes 3. Each line of separate electrodes forms lines with an anti-pole system, common for two or more columns, only one display cell. Fig. i, this is ensured by the fact that each of the anode electrodes 3 is insulated in some way (for example, by vitrification) along the entire length except for those places that geometrically correspond to one of the three holes in the dielectric plate 1 (the insulated areas on the anode electrodes 3 are shown as thick lines). The panel (see Fig. 2) has cathodes common for two columns of holes and two anode electrodes 3 and 4, corresponding to one row of holes. The anode electrodes are shown in modification versions: straight 3 or comb 4. Anode electrodes 3 and 4 are placed in the slots of the dielectric plate 1; grooves are located on both sides of the lowercase holes. The grooves are connected by grooves from, to the version (through one hole for each groove). In the alternating current indicator panel (see Fig. 3), the electrodes of opposite systems are shaped: columns 5 and lines 6. This is necessary in order to eliminate the intersection of the electrodes of opposite systems in all places, such as those by the display 7. The excitation of any display cell is provided by applying a supply voltage to one of the column electrodes and one of the row electrodes. It is advisable to carry out multi-color indicator panels according to the proposed invention, since it is possible to separately control k different colors with k line electrodes. When implementing monostable panels, i.e. panels that do not have internal memory, their functionality can be extended. Thus, for example, the brightness of the displayed image can be increased by times due to the simultaneous excitation of the display cells in K columns, while in the known monostable panels it is possible to excite the display cells of only one column. The ratio of the number of pins of the proposed display panel N to the number of pins of known panels fn + P is determined by the expression: о (1 N f p.

The optimum K the ratio jfji is equal to i / ft /; the minimum value of g | in this case is g (/,) ("/" j W) IN is less than f nj Considering the fact that k can take only integer values and in the sense of If 2, the realization of the invention is - ae at nj 4.
