Definitions

  • the present invention relates to a control circuit for an alternating type plasma panel.
  • Plasma panels of the alternative type are well known in the prior art.
  • the present invention provides an integrated circuit designed to operate with the two arrays of electrodes of the panel, without complication of the commands, and which therefore does not have the drawbacks of the Texas SN 75501 N circuit.
  • the present invention relates to a circuit for controlling an alternating type plasma panel, ensuring the generation of the maintenance signals, and of the selective signals, for writing and erasing the panel, these signals being applied between two electrodes.
  • this control circuit comprising integrated circuits provided in particular with a logic circuit defining the signal to be executed, its duration and the electrodes on which this signal will be active;
  • FIG. 1 the maintenance inscription and erasure signals which are applied to the cells of the panel are shown.
  • Each cell is constituted by the gas space located at the intersection of two electrodes belonging to the two networks of orthogonal electrodes of the panel.
  • Each cell is found setting control signals V x -Vy, shown in Figure 1, and constituted by the difference of the voltages V x and Vy applied to the two electrodes between which it is located.
  • the dotted lines represent the signals V x -Vy which must be applied to write or delete a cell and the signals are represented by asterisks.
  • V x -Vy to be applied to cells which must not be registered or deleted.
  • FIGS. 2 to 5 these two modes of representation have also been used for the selective signals.
  • FIGS. 2 and 3 show the signals V x and Vy which are applied to each of the electrode arrays to obtain the signals V x -Vy of FIG. 1.
  • the signals V x participate in the preparation of the selective recording and erasing signals and transmit the reference voltage of the maintenance signals, that is to say from 0 V on the figure 2.
  • Maintenance signals are not produced by integrated circuits but by amplifiers external to integrated circuits.
  • the integrated circuits only transmit the maintenance signals.
  • the integrated circuits according to the invention are produced so as to be able to withstand a voltage of 100 volts.
  • Vy which evolves between -100 V and + 100 V
  • V, f which follows the maintenance signals which also evolve between -100 V and + 100 V.
  • This floating reference voltage V is shown in FIG. 4. It can be seen, with respect to the voltage Vy in FIG. 3, that V r. f follows the maintenance signals and when developing selective signals, the voltage V rf follows the lowest potential that it is possible to apply to the electrodes.
  • Vy - V rf which varies between 0 and 100 V.
  • control circuit of a plasma panel comprises integrated circuits associated with amplifiers for the development of maintenance signals and each integrated circuit notably comprises a logic circuit defining the signal to be executed, its duration and the electrodes on which this signal will be active.
  • FIG. 2 of French patent 2,547,091 the structure of a logic circuit is shown which is part of an integrated circuit.
  • Each logic circuit essentially consists of shift registers with serial input and parallel outputs and a decoding and validation system. Therefore, the data or logical addresses designating the active and non-active electrodes are entered in series in the shift registers and are found in parallel on the outputs of the registers which correspond respectively to the electrodes of the plasma panel. An order defining the recording or erasing signal to be applied to the active electrodes then validates the parallel outputs of the registers to a low voltage / high voltage interface circuit.
  • logic circuits are produced which satisfy the following logic table:
  • the "Strobe” signal is an input of the logic circuit which by convention when it is at "1 indicates that an integrated circuit is not selected and when it is at" 0 "indicates that an integrated circuit is selected.
  • the signal "Inv” is the signal discussed above which, by convention, when it is “0” indicates that an integrated circuit is used on one of the electrode networks, the x-electrodes which receive V x in our example and which when it is at "1 indicates that an integrated circuit is used on the other electrode network, the electrodes at y which receive Vy in our example.
  • a bit of the shift register is, by convention, in state 1 if one wishes to activate an electrode and in state 0 if one does not wish to activate an electrode.
  • the shift register with serial input of the data D and with parallel outputs has been designated by the reference 1.
  • This register receives a clock signal H.
  • the acquisition of the data in the register and the application of an order to the electrodes of the panel are dissociated in time.
  • the data D is entered in series in the register at the rate of the data acquisition clock H.
  • a bit of the register is reserved for each controlled electrode.
  • This logic circuit conventionally comprises a decoding and validation circuit 6 which, during the duration of the signal to be executed, validates or not the outputs which go to the low voltage / high voltage, LV / HV interface, reference 5; this interface allows signals of 100 V amplitude to be applied directly to the electrodes
  • Access to the panel is therefore by point segments in rows and columns. Each point of these segments is defined as active or not. by a bit of a shift register.
  • the decoding and validation system 6 comprises inverted AND circuits 2. Each circuit 2 is connected to one of the outputs of register 1 and to the output of an inverter 3 which receives the Strobe signal. This information is common to all the circuits 2 forming part of the same integrated circuit.
  • An inverted exclusive OR circuit 4 receives the output of a circuit 2 and the signal Inv which is generally the same for the same integrated circuit.
  • the outputs of the reverse exclusive OR circuits 4 are connected to the low voltage / high voltage interface 5.
  • the signal Inv can be permanently connected at the high level or at the low level.
  • the plasma panel provided with a control circuit according to the invention can operate in these two modes.
  • FIG 7 there is shown - schematically a plasma panel 7 surrounded by integrated circuits 8 of its control circuit.
  • the amplifiers associated with the integrated circuits are not shown.
  • Each integrated circuit generally controls 32 electrodes.
  • the integrated circuits controlling one of the networks of electrodes have their pin Inv connected at the low level, that is to say to the ground of the device and the integrated circuits controlling the other network of electrodes have their Inv pin connected at the high level, to a voltage V cc1 .
  • the strobe signal is specific to each integrated circuit.
  • the signals St1y, St2y ... Stny and the St1x, St2x ... Stnx are shown.
  • the data Dx and Dy and the clock signals H x and H y use the same connection for the integrated circuits of the same network.
  • the panel shown in Figure 7 operates in overprint mode.
  • FIG 8 there is shown - schematically a plasma panel 7 surrounded by integrated circuits 8 in the case where it is desired to operate in the image replacement mode by complete lines.
  • the inputs Inv are connected at the high level to V cc1 .
  • the "Strobe" inputs St 1 y, St 2 y ... St n y are specific to each integrated circuit, and the data Dy, the clock signals Hy are sent over a single connection for all the integrated circuits.
  • a small number of signals can be used to control the panel.
  • the data signal D ix for the circuits controlling the columns and the Strobe signal for the circuits controlling the lines.
