Definitions

  • the invention relates to a circuit arrangement for controlling a VFD, LED or LCD display.
  • Such advertisements are e.g. widely used in small electrical appliances. You serve et al to display the time or temperature. With electronic stove time switches on such displays there are also signs for the set one Operating mode of the stove or oven or for other functions such as Alarm or radio reception. A numerical display (e.g. for the time) appears here usually realized using a 7-segment display.
  • Such displays are controlled according to the type of each Display (VFD, LED, LCD) each different.
  • VFD vacuum fluorescence display
  • the individual, corresponding segments of the different (7-segment) digits are connected in parallel with each other and form the anodes.
  • grids Between the heated cathodes and the segments serving as anodes are attached grids, which each extend over the area of a digit.
  • a segment of a certain number lights up when both the anode corresponding to this segment as well as the one corresponding to this number Grid is at positive voltage. Via multiplex control of the segments and the digits are therefore each individual segment of each individual Number can be controlled separately.
  • each segment In the case of a light-emitting diode display (LED), the individual segments are the digits each formed by individual light emitting diodes. The individual, corresponding to each other Segments of the different digits are again parallel to each other interconnects and form the cathode, while the various digits form the anodes.
  • each segment can be controlled by means of multiplex can be addressed separately.
  • VFD has either positive voltage at the connections or no voltage is applied while on the connections of the LED display positive (for digits) or negative (for segments) or no voltage applied becomes.
  • VFD with a relatively high voltage of 16 operated up to 30 V, but low current of 0.1 to 2 mA, while an LED display only a small voltage of about 2 V, but a larger current of 2 up to 20 mA required.
  • liquid crystal display LCD
  • An LCD is now constructed in such a way that up to 3 segments are parallel to each other are connected and thus form an electrode.
  • the other electrode is through three back electrodes (COM) formed, each one of the three with each other parallel connected segments are assigned.
  • COM back electrodes
  • This way is also here Multiplex control possible again.
  • here are up to the individual Connections of the display not only two voltage values (positive or negative and zero), but also intermediate voltage values (in the described case 1/3 and 2/3 of the voltage) so that a targeted reloading of individual elements without Influencing the other elements is possible.
  • the ability to drive a VFD, LED and LCD display is thereby achieved that at least two control blocks are provided, one of the Control blocks generates the control signals necessary for an LCD display and the other the one necessary for a VFD or LED or for both displays Control signals generated.
  • the control signals of the control blocks become common Driver module supplied, the corresponding from these control signals Control signals for the VFD / LED display and for the LCD display are generated and passes it on to the corresponding ad.
  • control blocks are provided, one of which one each for the LCD, VFD and LED displays the necessary control signals supplies.
  • one or more storage elements can be provided are assigned to the individual control blocks.
  • the driver module has several driver elements on, each with a connection of the VFD, LED or LCD display is connected and this connection a corresponding control signal supplies.
  • each driver element with each of the Control blocks is connected so that it is all used to control the connection necessary control signals are supplied to the connected display.
  • control signals of the control blocks in the driver elements are preferably such interconnects that the connection of the connected display the appropriate one Control signal is supplied. This interconnection takes place in a further development of Invention depending on the type of display connected.
  • control logic, the at least one memory element and the Control blocks executed digitally, while the driver block executed analog is.
  • a circuit arrangement 1 for controlling a VFD, LED or LCD display 2 has a data receiver 3, which is used to control the Display necessary data from a microprocessor 4, which receives the data receiver 3 simultaneously supplied with a time 4.1.
  • the data receiver 3 passes the received data on to a control logic 5.
  • the control logic 5 checks the received data and decodes it by extracting from the received Data addresses, control words and commands extracted. The commands contain the actual display data.
  • This display data is sent to a data memory 6 passed on and saved there. They remain saved as long as until the display is to be changed. Then new display data in the Data memory 6 saved.
  • control logic 5 shares a first control block 7, which is the generation of control signals required for an LCD display, and a second Control block 8, which the generation of for a VFD or LED display necessary Control signals, with which control mode is set (e.g. VFD / LED 5-fold, 6-fold or 7-fold multiplex, LCD 3-fold multiplex, night reduction or load shedding; see below).
  • the selected mode is in the ROM block 9 stored, which is in operative connection with the control logic 5.
  • control block 7 or control block 8 active. Using the data memory 6 The active control block 7 or 8 generates the display data provided in the usual way and further explained below for the respective display 2 necessary control signals COM 1 to 3 and S 1 to 13 (LCD) or G 1 to 7 and S 1 to 9 (VFD / LED) (see also below).
  • the control signals from the control block 8 still pass through the level shifter 10, in which, in the presence of a VFD mode, the levels of the control signals from usual 3.3 V to 30 V necessary for a VFD. In the event of In LED mode, this level increase is not necessary.
  • the information about the set mode receives the level shifter 10 as well as the control blocks 7 and 8 from the control logic 5.
  • the control signals of the control blocks 7 and 8 then arrive at the driver module 11.
  • both control blocks 7 and 8 can be independent of set mode are active at all times. In this case, however, it is necessary that the driver elements 11.1 to 11.16 control signals depending on the mode set (LCD or VFD / LED) received by only one of the control blocks 7 and 8. The the driver elements 11.1 to 11.16 receive corresponding information directly from the control logic 5.
  • the control logic 5 also controls a reset circuit 12 for the microprocessor 4, a buzzer circuit 13 for a buzzer 14 and a driver 15 for controlling relays 16 and 17.
  • a voltage supply for the individual components of the circuit arrangement 1 is not drawn for the sake of clarity; the power supply takes place however in the usual way.
  • Figure 2a shows the light segments of a VFD or an LED display. With a designated segments are interconnected in parallel and with the connector S1 connected, the elements labeled b to the terminal S2, etc.
  • the connections G1 to G7 are each with a number (possibly connected with adjacent symbols) extending grid.
  • the control for an LED display is basically the same as straight described, only that a negative instead of a positive at the connections S1 to S9 Voltage is present.
  • the display elements of an LCD are shown in FIG. 3a. Up to three of each Display elements are interconnected in parallel and to connections S1 connected up to S13. The back electrodes of the three elements are each on the Connection COM 1, COM 2 or COM 3 connected.
  • FIG 3b is the time course of the connections COM 1, COM 2 and COM 3 as well as signals present at connection S12, where it is a standard procedure for controlling an LCD.
  • the Andes Connections S1 to S13 are compared to the signals at COM 1, COM 2 and COM 3 signals present in opposite polarity, so that e.g. on the upper display element S12 a voltage corresponding to COM 1 minus S12 is present, on the middle display element S12 corresponding to COM 2 minus S12 and on the lower display element S12 corresponding to COM 3 minus S12.
  • the Voltage differences, which on the upper display element (accordingly COM 1 minus S12) are too small for the crystals to align could. There is therefore no display there. In the middle and lower Display element, however, large voltage differences of 2 U occur, which is why here an alignment of the crystals and thus an indication is given.
  • FIG. 4 now shows a basic circuit diagram of the driver elements 11.1 to 11.16 each included circuitry for generating the control signals for the display 2.
  • the control block 8 switches 18 and 19 driven by digital signals W4 and W0.
  • a signal i.e. Voltage present
  • the switch 18 is closed via a digital signal W4
  • the switch 18 is opened and the Switch 19 closed by a digital signal W0.
  • the (accordingly dimensioned) switches 18 and 19 for a VFD or LED element suitable signal are generated.
  • Switches 19, 20, 21 and 22 are used to control an LCD element. By closing the corresponding switch using the associated, The digital signal W0, W1, W2 or W3 coming from the control block 7 can Voltage at output A can be adjusted to 0, 1/3 U, 2/3 U or U, where U is typically 3.3 V.
  • the control logic 5, the memory element 6 and the control blocks 7 and 8 of the Circuit arrangement 1 are implemented digitally, while the driver module 11 is carried out analogously with the driver elements 11.1 to 11.16.
  • the whole Circuit arrangement 1 is designed as an integrated circuit (IC). In these IC are also the reset circuit 12, the buzzer circuit 13 and the relay driver 15 integrated.
