The disclosed part of this patent file comprises data protected by copyright.When this patent document or this patent publication occurred with patent and trademark office patent file or data, this copyright holder did not oppose with any form of patent document or patent disclosure it duplicate again, otherwise all rights reserved, and violators must be brought to justice.

The present invention relates to a kind of illuminator that cooperatively interacts with main frame such as game machine.The invention particularly relates to a kind of modified illuminator that preferably cooperatively interacts with main frame, and this system is with the sequential illumination corresponding to the state indication of sampling from main frame non-invasi.

Resemble the so many machines of automatic vending machine and game machine and light one or more bulbs of machine exterior according to the internal state of this machine.For example, a kind of slot machine is lighted each different incandescent light bulb to illuminate its " pay lines (payline) " according to the number that drops into coin in this machine.

But incandescent lamp bulb expends a large amount of electric energy.Thereby wish to replace incandescent lamp bulb with electroluminescence (EL) lamp, because the EL lamp expends less electric energy.Electroluminescence (EL) lamp is the light source that contains a kind of special fluorescent material or fluorescent material potpourri, and these fluorescent materials are luminous when they are subjected to electric field action.Perhaps the more important thing is, wish to revise the mode of lighting lamp according to the internal state of machine.For example, can change the mode of lighting lamp into and people are attracted to machine come here or Useful Information is provided.

Usually, many circuit that are used for controlling a machine illuminator can't be with compatible to the low power sources power supply.In addition, be used for controlling the circuit of the mode of lighting lamp usually at machine intimate.Therefore, it is very expensive to revise this illuminator.This point is particularly outstanding when this machine is game machine, because game method in state requires: after the game machine internal circuit was done any change, these game machines all will be subjected to many-sided test and authentication.

In the past, the EL lamp needs high-tension circuit so that their work.For this reason, need bulky power supply, inverter and/or other electronic circuits and battery (being used for cordless operation) to make lamp luminous so that suitable electric energy to be provided.Power supply is more much bigger than lamp Pang usually.

Typical EL lamp is powered by high pressure (usually greater than 10V) power supply.These power supplys often are AC (interchange) type power supply.Some EL lamps are directly by standard civil power (being generally 120V exchanges) power supply.For battery operated rather than civil power work, need an inverter or other circuit that the DC of battery (direct current) electricity is raise usually and/or transform to high pressure AC (interchange).

EL lamp display circuit can comprise the counter of the section of the EL display that a storer, audio frequency sequencer and qualification are to be lighted.But, in a kind of like this system the control of Output Display Unit is subjected to the restriction of the finite data processing power of storer and counter.Because a fixing AC voltage waveform generator drives this display, so this output also is subjected to following restriction: the dynamically color and the brightness of control Output Display Unit.

The present invention is a kind of modified illuminator, uses for main frame, be used for according to provide from host computer system and be used in addition producing illuminating effect to the lamp power supply signal of the lamp power supply of main frame.An EL lamp system has a plurality of EL modulation elements.Sequencing circuit provides an EL lamp drive signal each EL modulation element with independent control EL lamp system, thereby the EL modulation element is lighted with the order collective corresponding to this EL lamp drive signal.Specifically, sequencing circuit comprises a microcontroller that a drive signal is provided that is connected on the power circuit, and this drive signal has suitable amplitude and frequency to drive electroluminescent display element.Select circuit to receive a plurality of signals and receive drive signal for one from power circuit from microcontroller.This selection circuit is delivered to drive signal each independently on the electroluminescent display element selectively according to the signal that receives from microcontroller.By this set, microcontroller opens each described display element or cuts out them with an order, the demonstration of generation activity thus (animated display).Circuit for signal conditioning provides EL lamp drive signal to the sampling of the lamp power supply signal intervention property that provides from host computer system and in response to this.

This circuit can also comprise load capacitance, can switch them selectively by controller, thereby they also presents capacitive load to drive signal generator except the capacitive load that is presented by the electroluminescence panel element.These load capacitances not only can addressing with drive signal is switched to relevant " spike " phenomenon of another element from an element, but also the capacitive load difference that can be caused the different size element that is activated at the difference place with this order affords redress.

Fig. 1 expresses a modified electroluminescence (EL) illuminator 100 according to one embodiment of the invention with the form of block diagram.This EL illuminator expends still less energy than the incandescent lamp bulb of a main frame that uses by other mode.On the other hand, even used incandescent lamp bulb, this EL illuminator 100 also can provide extra illuminating effect with minimum additional electrical energy.By improving a machine, very easily revise the mode of lighting lamp according to the internal state of this machine with modified EL illuminator 100.

Among the embodiment with the block diagram formal specification in Fig. 1, system 100 comprises three EL lamp plate 108a, 108b and 108c (in this instructions so-called 108).But each EL lamp plate 108 comprises the EL modulation element of a plurality of drive.These plates are driven by an electronic control module 101.Each plate by electronic control module 101 and be contained in order parallel circuit seq1, seq2 and seq3 independent in the sequencing circuit 106 and drive respectively.For example, as shown in Figure 2, if game machine 104 is slot machines, then lamp plate 108a, 108b and 108c are suitable for being placed on " top view window " 152, " shaking view window " 154 and " the belly view window " 156 of this slot machine 104.As 158 indications of label among Fig. 2, the additional zone of slot machine 104 can be equipped with an EL plate, in order to notice is attracted to " currency is collected the place " function of slot machine 104.

When each lamp of an AC driving electric current or pulsating direct current electric current supply EL plate, these lamps have been turned on.The brightness of lamp is according to the amplitude and the frequency change of this lamp drive current, and the color of lamp is according to for example frequency change of this drive current.

Fig. 3 illustrates how modified illuminator 100 is connected on the game machine 104 according to one embodiment of the present of invention.Electronic control module 101 comprises one and is used for that (through a standard plug 303) is connected to the connector 301 on standard 120V, the 60HZ AC power.Among Fig. 3, obtain being used for controlling the single state control signal of the EL plate 108a on the zone 158 that will be placed on slot machine 104 from game machine 104.Specifically, the internal state of the signal indication game machine 104 that is produced by game machine 104, these condition indicative signals are preferably by the sampling of the circuit non-invasi in the electronic control module 101.That is, be preferably under the condition of the internal state that does not influence game machine 104 these condition indicative signals samplings.

For example, can be used as condition indicative signal to a power supply signal that provides by game machine 104 to an outside incandescent lamp power supply.By tapping into the power supply signal of powering it is sampled to incandescent lamp.Its example is shown among Fig. 3, wherein the power supply signal that is offered " coin operated lamp " 302 by game machine 104 is sampled, and through connector 305 this power supply signal is offered electronic control module 101.As another example, can stay the former light modulation of this machine bubble in position, optical sensor is used for determining when lights this bulb.Its problem is that this former light modulation bubble may burn out.As another example, can be with a coil around providing to bulb around the lead of power supply signal, the electric current in the lead that is measured by this coil produces magnetic field and as condition indicative signal.In all cases, purpose all is for non-invasi ground the power supply signal that offers bulb to be sampled.(on the other hand, but not best, can be directly provide a condition indicative signal from other circuit of microcontroller or game machine 104.)

According to the condition indicative signal that is provided by game machine 104, electronic control module 101 produces the lamp plate drive signal that is used for driving an EL lamp plate (in this case, being EL plate 108a shown in Figure 1).As shown in Figure 3, the lamp plate drive signal is offered EL lamp plate 108a from electronic control module 101 through stube cable 309.These lamp plates can be by MKS of Bridgoton, the large quantities of supplies of New Jersey.

Except that the EL plate, electroluminescence (EL) lamp also occurs with many forms, for example EL lamp line or EL filament.This illuminator can comprise any in the EL lamp of these forms.The EL plate is the EL lamp bar on a kind of liner plate.Preferably by deposit fluorescent material compound selectively and selectively the rear electrode (conductive rear electrode) (polymeric material that for example contains the top load silver particles) of deposit conduction make the EL plate.Can be on this lamp plate a plurality of parts of this fluorescence electrode structure of deposit to constitute pattern.Each part is connected respectively on the power supply, thus their Push And Releases independently, thereby be convenient to movable the demonstration.Though described embodiments of the invention with reference to the EL plate, also can replace the EL plate with single or multiple EL filaments.

A detailed embodiment of electronic control module 101 is described referring now to Fig. 4 to 7.Fig. 4 is highest schematic diagram than the embodiment of more detailed electronic control module 101 embodiment illustrated in fig. 1 of expression.As shown in Figure 4, electronic control module 101 is used for lighting selectively with the order of an activity EL lamp plate element at 158 places, zone of slot machine 101.Also referring to Fig. 4, host interface circuit 102 from the condition indicative signal of game machine 104 (for example receives, be used for sampled value to the power supply signal of an incandescence bulb powered), and this sampled signal is adjusted to appropriate value (for example, by moving the level of this sampled signal) to input to microcontroller 406.The details of this conversion depends on specific game machine 104, specifically depends on the level of sampled signal.

Through an optoisolator 404 or 405 condition indicative signal of being regulated is offered microcontroller 406.Optoisolator 404 or 405 separates electronic control module 101 and game machine 104 so that protect game machine 104 internal circuits not to be subjected to the influence (for example, by by the result of release from the people's of object for appreciation game machine 104 the impact that static caused) of the low-frequency disturbance that may improve in electronic control module 101.If electronic control module 101 is directly connected on the internal circuit of game machine 104, then probably any static of electronic control module 101 is discharged and all can be directly coupled in the game machine 104, make its process chaotic and cause " hopper " dumping.

Drive signal generator 408 by power supply 410 power supplies also finally provides a sinusoidal drive signals to drive EL element through the pin of connector 416 through an EL driving circuit 412.The application number of quoting as above-mentioned reference is 08/591, described in 014 the file, microcontroller 406 starts the on-off circuit in the EL driving circuit 412 so that on-off circuit provides drive signal to EL element selectively selectively according to the condition indicative signal of being regulated.(describing these on-off circuits with reference to Fig. 6 later on).Therefore, light EL element with the order of an activity.Microcontroller 406 is connected on the inverter 408 through an ENABLE-H signal.By determining this ENABLE-H signal, microcontroller 406 can forbid that drive signal generator 408 provides drive signal.

Express details among Fig. 5 in more detail according to the drive signal generator 408 of one embodiment of the present of invention.Inverter 502 provides sinusoidal drive signals.Capacitor C6 and C6A provide the load capacitance of restriction from the maximum output voltage of inverter 502.

The amplitude of the sinusoidal drive signals that is provided by inverter 502 is provided low pressure monitor 504.Specifically, when EL lamp/element broke down, they generally became dead short and/or partial short circuit.This can make inverter 502 seriously transship, because the electric current that it will manage to provide enough is to drive the EL element of short circuit.This low pressure monitor 504 is voltage comparator circuits.It is transformed into the sinusoidal output voltage of inverter 502 DC voltage that is directly proportional with the output voltage of inverter 502.When an EL element short circuit and output--the LVOLT-H of low pressure comparer 504 is confirmed in the output of inverter 502 when dropping under the value that is set by resistance R 11, R12 and R13.This LVOLT-H output is coupled light on the microcontroller 406.Microcontroller 406 is programmed monitoring the LVOLT-H signal, detecting when having confirmed this LVOLT-H signal disables inverter 502 work.This has prevented that the excess current that can draw by inverter 502 from causing permanent damages to inverter 502.

Zero-crossing detector 506 can be used to detect the drive signal that is provided by inverter 502 and when crosses no-voltage amplitude place.When detecting zero crossing, zero-crossing detector 506 provides a ZEROX-E control signal to the RB1 of microcontroller 406 input end (Fig. 4).Have only when the drive signal that is provided by inverter 408 has the no-voltage of being about amplitude, microcontroller just switches the on-off circuit in the EL driving circuit 412, thereby begins to provide drive signal through connector 416.Like this, can protect EL element to avoid the drive signal input (that is spike) of sharp increase.Except may causing video " flicker " worry, such drive signal spike may cause the electric capacity in the EL element to puncture, and EL element can not be worked.

The part of a specific embodiment of EL driving circuit 412 is described referring now to Fig. 6.Specifically, the EL drive signal that is produced by drive signal generator 408 is offered an AC HOT input end of EL driving circuit 412.A plurality of on-off circuit 602a comprise a switch control input end (being respectively RCO to RC7 and RB7) and a drive signal output terminal (being respectively DRCO to DRC7 and DRB7) to each of 602i.Also connect on-off circuit 602a to such an extent that can receive AC HOT input end to each of 602i to receive the EL drive signal that produces by drive signal generator 408.On-off circuit 602a comprises four commutation diodes and a bipolar junction transistor to 602i.

According to the program of carrying out by microcontroller, microcontroller confirm respectively its each be connected respectively to the switch control output end RCO of on-off circuit 602a on to RC7 and RB7 to the switch control input end RCO of 602i to RC7 and RB7.Therewith responsively, when confirming the switch control input end of a special key circuit, that on-off circuit sends the drive signal from AC HOT end to the output terminal of this on-off circuit.Referring to Fig. 4, as can be seen, each on-off circuit 602a is connected on the independent EL element of " currency is collected the place " EL plate through connector 4016 to 602i, is somebody's turn to do the zone 158 (Fig. 2) that " the currency place of collecting " EL plate is positioned at game machine 104 again.

Also, backup circuit breaker circuit 604a and 604b are discussed now referring to Fig. 6.Backup circuit breaker circuit 604a and 604b respond respectively by the switch control output end RB5 of microcontroller 406 and RB6 and offer the switch control input end RB5 of backup circuit breaker circuit 604a and 604b and the switching signal of RB6 respectively.Specifically, the drive signal that backup circuit breaker circuit 604a and 604b handle are held from AC HOT sends output terminal DRB5 and the DRB6 of backup circuit breaker circuit 604a and 604b respectively to, wherein confirms switch control input end RB5 and the RB6 of backup circuit breaker circuit 604a and 604b respectively.Drive signal is added to load capacitance C7 and C7A respectively or is added on load capacitance C8 and the C8A through output terminal DRB6 and DRB7.

Discuss now to load capacitance C7 and C7A or the reason of drive signal is provided to load capacitance C8 and C8A.The inverter 502 (Fig. 5) of drive signal generator 408 had not only depended on load but also can self compensation.(in a preferred embodiment, inverter 502 provides " NS " serial inverter by NEC).That is to say, inverter 502 comprises such circuit, promptly by in the illumination order arbitrarily the load capacitance value that drives of particular point place determine the frequency (nominally the load of one or more EL element is through driving for one or several specific on-off circuit that the EL driving circuit 412 that a drive signal selects is provided) of the sinusoidal drive signals that inverter 502 provides.In addition, the capacitance of EL element changes with the aging of EL element.Inverter 502 detects the driving signal frequency that this electric capacity changes and adjustment is produced, thereby even also can light EL element with a constant relatively brightness when its capacitance changes.

Because the capacitive load of an EL element is mainly determined by its specification, so when a plurality of EL element that driven by single inverter 502 with an order were different size, the frequency of the sinusoidal drive signals that is provided by inverter 408 will be according to the specification and the capacitance variation of the EL element that is driven (or its combination).Therefore, if not to being regulated by the different loads that various combination produced of EL element, the brightness of lighting each EL element so has very big variation mutually by comparison.This phenomenon visually has no attractive force.

But by load capacitance C7 and C7A or load capacitance C8 and C8A are added on the capacitive load that is stood by inverter 502, inverter 502 stands a substantially invariable capacitive load in whole illumination order.By keeping this substantially invariable capacitive load, can make the frequency of the sinusoidal drive signals that is provided by inverter 502 keep substantially constant.Therefore, during this order, brightness each time point in the illumination order of lighting each EL element all keeps constant.This makes inverter 502 can " detect " each specific EL element because of the aging capacitance variation that causes and compensate it.

The variation of the EL element specification that is driven and the expectation percentage tolerances that brightness changes are all depended in the arrangement of the load capacitor on the number of backup circuit breaker circuit and load capacitance, the capacitance of load capacitance and desired even the inverter 502 beyond the capacitive load.An order that comprises the cut-in stand-by on-off circuit of load capacitor in the load that is stood by inverter 408 can pre-determine and be included in the sequencer of being carried out by microcontroller 406.That is to say, on-off circuit in control EL driving circuit 412 is to light the EL element, and also will programme in advance to microcontroller 406 to be added to each load capacitor (or its combination) on the inverter 502 it according to the variation of lighting the required load capacitance of one or more EL element with control backup circuit breaker circuit selectively.

In the embodiment shown in fig. 4, capacitor C8 and C8A have effective capacitance 0.01uF, and capacitor C7 and C7A have effective capacitance 0.022uF.Like this, the load capacitance variation that has four energy to obtain by allowing DRVR#A and DRVR#B selectively, as shown below:

Total " adding " load of DRVR#A DRVR#B

Forbid 0.0 μ F

Allow to forbid 0.01 μ F

Forbid allowing 0.022 μ F

Allow 0.032 μ F

Can determine the actual value and their configuration (that is, by testing with different values and the resulting illumination order of qualitative examination) of load capacitor qualitatively.But, preferably can make the EL element surface area that during the illumination order, is driven qualitative relevant with an equivalent capacitance value.A storer (for example, ROM (read-only memory)) can be set.A table in the storer comprises a plurality of list items, and each list item corresponding to a step and indication which load capacitance during the corresponding step of this order of illumination order is waited to connect.

Fig. 7 brief description an embodiment of microcontroller 406 and relevant glue logic.

Fig. 8 has illustrated a kind of like this phenomenon, promptly, if microcontroller 406 before connecting corresponding to the on-off circuit of second EL element (being called " CELL#2 " among Fig. 8) in short-term (or even weak point of a few microsecond) close (promptly corresponding to the on-off circuit of first EL element (being called " CELL#1 " among Fig. 8), 602a in the 602i), and the sinusoidal drive signals that is produced by inverter 502 is in crest location, then this drive signal can produce spike (greater than 400V) because of reducing capacitive load suddenly, and may damage inverter 502 and EL element #2 these two or one of them.

Even how Fig. 9 explanation avoids the spike in the drive signal under the condition that does not adopt zero-crossing detector 506.At first, before closing, connect on-off circuit corresponding to CELL#2 corresponding to the on-off circuit of CELL#1.Before the on-off circuit of connecting corresponding to CELL#2, connect a on-off circuit (or several on-off circuit) corresponding to a load capacitor (or several load capacitor).Spike can not take place in the place that is added with large capacitive load when connecting subsequently corresponding to the on-off circuit of CELL#2 on (0 to 5 μ s after for example connecting corresponding to the on-off circuit of load capacitor) inverter 502.At last, be added on the inverter 502 time enough (for example, about 100us) after stable in load, CELL#1 closes.

Thereby appendix A is the book that can be carried out the assembly language sign indicating number of an order by microcontroller 406.

In a fully integrated driving circuit, microcontroller not only can be controlled and turn on each lamp, and can control the brightness and the color of lamp.Microcontroller 406 can be used for the demonstration of on the one dimension of all kinds, two and three dimensions luminous object activity of constructing.The example of such luminous object comprises cloth, the artwork, molded part and information display.For example, in cloth, electroluminescence wire can be used for movable sign, design or other features.

The conceptual block diagram of another embodiment of EL plate control device is shown among Figure 10.In this embodiment, color, brightness and the switching sequence of a plurality of EL lamps 1102 of microcontroller 1100 controls.The EL plate of EL driver 1106 under microcontroller 1100 controls provides alternating current.A plurality of solid-state switches 1104 are connected to EL driver 1106 on the EL plate 1102.The label of microcontroller 1100 is that 1 to n I/0 pin one 110 outputs to control signal on the control line of on-off circuit 1104.On-off circuit 1104 controls have electrical energy flows to cross the circuit of EL driver 1106 and EL plate 1102.

Control line 1108 not necessarily.If be provided with control line 1108, then control line 1108 is connected to microcontroller 1100 on the EL driver 1106.By control line 1108, microcontroller 1100 controls are by the frequency and the amplitude of the electric current of EL driver 1106 outputs.Frequency, duty cycle and the intensity of driver 1106 output currents will be determined the color and the brightness of each EL lamp 1102.

The more detailed block representation of EL plate controller is in Figure 11 among Figure 10.

Microcontroller 1100 preferably has low-cost and few peripheral cell number.Resemble the PTC16C55 or the commercially availabie like this microcontroller of PIC16C57 that come from MICROCHIP and can be used as microcontroller 1100.But, also available any suitable microcontroller or microcontroller replace.

Pressure regulator 1202 is connected to battery on the microcontroller 1100 and the voltage from battery and is adjusted on the level that needs into microcontroller 1100 power supply stations.In this example, pressure regulator 1202 provides 5.0 volts of direct currents to microcontroller 1100.

Connect and to resemble a ceramic resonator or quartz crystal (XTAC), resistor and/or the such timing circuit 1204 of capacitor (one or more) so that provide timing signal to microcontroller 1100.Variation according to contain the present embodiment of an on-chip timer in microcontroller 1100 can need not timing circuit.

Knob (one or more) 1206 is connected on the microcontroller so that the user can control microcontroller such as ON/OFF, pattern selection, color and the output function regularly regulating.

EL driving circuit 1106 is made of oscillator (or function generator) 1208, power amplifier 1210 and transformer 1212.Transformer 1212 is connected to oscillator 1208 and power amplifier 1210 output terminal (Figure 10) of EL driving circuit 1106.The output of power amplifier 1210 reception oscillators 1208.This signal amplifies the elementary winding of driver transformer 1212 by power amplifier 1210 then.Oscillator 1208 can provide for example sine wave, square wave or sawtooth wave.The typical drive signal of coming from transformer 1212 transmission can be that for example a frequency is that 1000Hz, amplitude are 35 volts sinusoidal signal.

Can be from the type and the frequency of the waveform of oscillator 1208 output by microcontroller 1100 by control line (one or more) 1214 controls.Similarly, the gain of power amplifier 1210 can be by microcontroller 1100 by control line (one or more) 1216 controls.

The frequency that changes an EL lamp drive signal will influence its color and brightness.Frequency by changing drive signal and duty cycle make to become from grayish green or dark green color change to indigo plant or purple fully may.This is equivalent to moving near 150nm in the visible spectrum.

The amplitude that changes drive signal influences brightness.Can also change the brightness that to feel (below make an explanation) by the duty cycle of adjusting switching signal.

The on-off circuit 1104 that is connected on the I/O pin one 110 and controlled by these pins is connected to their EL plates 1102 separately on the EL driver 1106.Each on-off circuit 1104 comprises a high voltage transistor 1218.The base stage of each transistor 1218 is connected on the resistor 1220, and resistor 1220 is connected on the microcontroller 1100.The emitter of each transistor 1218 is held with being connected to, and the collector of each transistor 1218 is connected on the diode bridge 1222.Each EL plate 1102 is connected between the end of end of diode bridge 1222 and transformer 1212 secondary winding.

The on-off circuit 1104 that is used for the EL plate of each I/O pin control that is subjected to microcontroller 1100 all is living.The number of circuit 1104 is limited by the number of effective output pin on the microcontroller 1100, but, is not to use all output pins certainly.

In the work, Figure 10 and 11 embodiment play following effect.

Microcontroller 1100 is by I/O pin one 110 gauge tap circuit 1104.Its on-off circuit is closed in high level output (" 1 ") on any one I/O pin one 110, and this makes the EL drive current can flow through the corresponding EL plate 1102 of this switch, lights this lamp.Its on-off circuit is opened in low level output (" 0 ") on any one I/O pin one 110, and this forbids that the EL drive current flows through the corresponding EL plate 1202 of this on-off circuit, and switch is disconnected.Specifically, referring to Figure 11, high level output (" 1 ") makes current flowing resistance 1220, and this makes transistor 1218 conductings.This allows electric current to flow through transistor 1218, diode bridge rectifier 1222 and EL plate 1102, lights this EL plate thus.Similarly, low level output (" 0 ") is extinguished the EL plate.

If use control line 108, the then frequency and the amplitude of the driving voltage exported of microcontroller 1100 control EL driving circuits 1106.Like this, the color and the brightness of microcontroller 1100 control EL plate output demonstrations.

Knob (one or more) 1206 can be used for carrying out ON/OFF, the pattern of microcontroller and select and timing.For example, will make this controller work in a predetermined amount of time by a knob, after during this period of time, controller may be carried out a sleep instruction, is actually to make self to quit work.Before finishing, order shows continuously by knob 1206 order displays for the second time.Make by knob 1206 for the third time and show and to stop and controller is reset to standby mode.The current state of available pilot lamp flicker expression controller.

The state (that is, opening or closing) of its I/O pin one of microcontroller 1100 usefulness 110 each EL plate of control with export one with the pre-programmed activity on the EL plate to be shown corresponding order in proper order.When microcontroller was exported to its I/O pin to the next word in the activity command, the EL plate transformed to one and the new corresponding state of pattern.Like this, the pre-programmed DISPLAY ORDER is shown on the EL plate.

Because each EL plate is coupled on the I/O pin on the microcontroller 1100, so when microcontroller 1100 places an output on each the I/O pin one 110 that is coupled on the EL plate, just determined a complete state of EL plate.Realize the activity of EL plate by the state of bringing in constant renewal in 110 outputs of I/O pin one.

Two software approachs are used for I/O pin one 110 patterns are carried out sequencing.First method is word table of structure, and this word table establishment is the part of microcontroller programming, and this word table has been determined the state of all plates in each step in this order.For example, order can be one three step: all plates open, every a plate open, all plates close.If with 15 EL plates, then this is represented by following state table:

11111111 1111111

10101010 1010101

00000000 0000000

During microcontroller 1100 will be shown first row is exported to I/O pin one 110 fully, has opened all EL plates.After having waited for predetermined amount of time, the next line during microcontroller 1100 will be shown sends I/O pin one 110 to, closes the EL plate every.After another scheduled delay section, transmit last column, close all EL plates.

Second sequential grammar comprises the state of initialization I/O pin one 110, and calculates ensuing state according to former state and a selected bits handling function then.For example, " a chasing " pattern can be by being initialised to I/O pin one 110

10111111

Instruct in dextrorotation of this port execution then and realize.So next output order will be:

11011111

Used bit manipulation function can be can be by any composite function or the sequential function of microcontroller 1100 execution.This method has by reducing the required table size that is used for keeping required state saves the potential advantages of storage space.

A general problem is in the prior art relevant with the EL lamp: when continuing for some time these lamps of driving under the high frequency state, they will generate heat, and may finally burn out.Can regularly close hot EL plate by making microcontroller by the present invention, perhaps the EL plate opened, then alleviated this heating problem by signal is pulsed as if continuing for some time.

Figure 12 A and 12D show from microcontroller 1100, are used for the pulse signal of gauge tap circuit 1104.The subsignal that these signals can " be opened the stage " with them as an EL plate 1102 by microcontroller 1100 generations, or be equal to ground, external circuit can be used for making " opening signal " pulsation from microcontroller 1100.

Human eye has an eye storage characteristic, thereby the optical flare faster than 60Hz can not make us feeling flicker.Therefore, as long as make from the frequency of opening signal of I/O pin one 110 in 60Hz pulsation at least, the EL plate of then being lighted looks that one is heading straight for.

Figure 12 A expresses a pulse signal in 50% duty cycle of 60Hz flicker.At high level (" opening ") during the stage, by on-off circuit 1104, they are subjected to the control of pulse signal 12A from the high-frequency signal of transformer 1212 (shown in Figure 12 B).Final signal (shown in Figure 12 C) drives EL plate 1102, thereby lights it.Even the EL plate can be under higher frequency driven by driver 1106, they are in fact also only driven in half the time, and this is because they are not activated when hanging down when the pulse signal among Figure 12 A.This has significantly reduced undesirable EL plate heating.

Because the pulse signal among Figure 12 A is produced by microcontroller 1100, so can be easy to change duty cycle.Figure 12 D expresses the 60Hz example of 75% duty cycle pulse signal of flicker down.The duty cycle that changes this pulse signal makes the people can change the perceived brightness of institute's isolychn.For each complete cycle of pulse signal among Figure 12 D because among Figure 12 B 3/4ths of drive signal time be " opening " and 1/4th time is " pass ", so this signal 3/4ths deliver to EL plate 1102.Because human eye is not linear fully with respect to duty cycle and perceived brightness, so 25% of duty cycle growth is felt to increase than 25% brightness low slightly by the beholder between Figure 12 A and Figure 12 D.

Can be assembled into a small and light fully integrated unit to above-mentioned new E L plate control device.In addition, can dynamically control color, brightness, perceived brightness and the heat of a plurality of EL plates or filament, so just be that a wide mobility scope creates conditions.

The block diagram of another embodiment of expression EL plate control device of the present invention among Figure 13.In this embodiment, EL plate 1412 is connected on the high-voltage drive 1410.Here express three EL plates in line with illustrative purposes, can certainly adopt more or less EL plate.Also have, if need not three plates that separate, a same available independent plate that is divided into a plurality of parts replaces.

The electric energy that microcontroller 1400 is accepted from pressure regulator 1404, and pressure regulator 1404 is connected on the battery 1406.Switch (one or more) 1402 is connected on the microcontroller 1400, and this switch 1402 can be used to resemble so various control function such as ON/OFF, pattern control and timing controlled.Pressure regulator 1408 is high pressure regulators that are used for providing to high-voltage drive 1410 electric energy.Usually, offer driver 1410 with 200 volts, but, also can adopt higher or lower voltage according to the special lighting requirement of three kinds of EL situations.

In the work, the lighting of the driver 1410 control EL plates 1412 of microcontroller 1400 by adopting an output enable (O E) line, polarity line, data line and a clock lines.The preferably independent line of data line, this bundle of lines data serial are packed into and are contained in the shift register in the driver 1410.For the application that requires the shorter load time, can be with many data lines.

Figure 14 is the detailed diagram of high-voltage drive 1410.Driver 1410 comprises a shift register 1500.This shift register 1500 and the information of clock synchronization ground reception from data line.Though do not express other shift register incoming lines, for example a register zero clearing line or a shift register direction control line, can be input to them the shift register 1500 from microcontroller 1400 yet.

Data from shift register 1500 outputs are input to the logical circuit 1502.Allow signal and polar signal according to the output from shift register 1500 inputs, logical circuit 1502 makes MOSFET 1504 and 1506 conductings or shutoff.EL plate 1412 is according to the state charge or discharge of their MOSFET, so that they are lighted.

In the work, microcontroller 1400 allows clock signal, polar signal and output signal to be transferred to each logical circuit 1502 in the high-voltage drive 1410.Clock signal and data-signal serial are input in the shift register 1500.Shift register 1500 synchronously moves on to second section to data from first section with clock signal, finally moves on to the 3rd section.In office meaning fixed time, and microcontroller 1400 control shift registers 1500 are present in the shift register 1500 thereby data-signal and clock signal are independent one " 1 " or ON position." 1 " in the shift register 1500 in one of three positions is corresponding to the current potential ON state of its respective logic circuit 1502.At each time clock place, " 1 " is moved down in shift register 1500.Like this, microcontroller 400 can be controlled the EL plate 1412 that will encourage." 0 " or OFF position are corresponding to the current potential OFF state in the respective logic circuit 1502.When being in the OFF state, logical circuit 1502 turn- offs MOSFET 1504 and 1506, thereby its EL plate 1412 is presented high-impedance state.

The OE signal is an electronegative potential active line.When this line when low, make its corresponding EL plate 1412 charge or discharge corresponding to the logical block 1502 of " 1 " in the shift register 1500 according to polar signal.As O E when being high, their corresponding M OSFET 1504 and 1506 of all logical circuit 1502 controls, thus EL plate 1412 is learnt high-voltage drive 1410 and is presented high-impedance state.In this state, discharge significantly without any a plate 1412 or charge.

Polarity line is used for selecting the charge polarity that stood by selected plate 1412 (that is the plate that corresponding " 1 ", is arranged) in shift register memories.The EL plate is only luminous when they are subjected to change in voltage." 1 " is selected a plate and output is allowed when effective in shift register, and to make polarity be high if turn-offs MOSFET 1506 by conducting MOSFET 1504, then this plate charged; If if by turn-offing MOSFET 1504 conducting MOSFET 1506 to make polarity be low, then to this plate discharge.Because 1412 storages of EL plate are from the electric charge (their effect is as electric capacity) of dc voltage source input, microcontroller 1400 preferably alternately changes the polarity line between Continuous Selection EL plate.

Figure 15 is a sequential chart, and it has illustrated that clock signal, data-signal, polar signal and output allow the mutual relationship of signal.Time interval t1 marks top in Figure 15 to the t3 level.In time interval t1, be preferably in the rising edge of clock signal place data-signal " 1 " is packed in first section of shift register memories 1500.Because output allows to be under an embargo, so all MOSFET 1504,1506 turn-off (high-impedance state).At this moment, in fact EL plate 1412 " sees " open circuit when browsing driver 1410.This means does not have EL plate 1412 in charge or discharge.

Data-signal is low at time interval t2 place, thereby shift register 1500 moves on to second section to " 1 " of before having packed into.Forbid that once more this output allows, therefore, all MOSFET1504,1506 turn-off.

Begin at t3, this output allows to be allowed to.At this moment " 1 " in shift register 1,500 second sections is latched in its logical circuit, this logical circuit makes a conducting among the MOSFET 1504,1506 subsequently.Determine to treat the MOSFET of conducting with polar signal.Polar signal is high at this moment in this example, and this is equivalent to make MOSFET 1504 conductings.This just makes electric current flow to middle EL plate from power supply, makes its charging, luminous.EL plate in the middle of following a period of time microcontroller starting, it will be low work with polar signal.This can make MOSFET 1504 turn-off and MOSFET 1506 conductings, makes electric current go out and make it luminous from this EL plate current.

The frequency of operation of clock signal control Driver Circuit 1410.Because clock signal is subjected to microcontroller 1400 controls, so its frequency and duty cycle certainly can be by the software changes of control microcontroller.General operating frequency range can be from 100Hz to 2000Hz.The frequency that changes clock signal with to Figure 10 embodiment in similar mode influence the brightness and the lighting colour of EL plate.

Allow line by sequential control clock line, data line, polarity line and output, color, brightness and the state of microcontroller 1400 control EL plates, the Visual Display of generation activity thus with a pre-programmed.

The block diagram of another embodiment of expression EL plate control device of the present invention among Figure 17.In this embodiment, EL plate 1806 is connected on the high-voltage drive 1800.High-voltage drive 1800 is placed and the similar circuit of the circuit of high-voltage drive shown in Figure 13 1410.But in the present embodiment, data line 1802a is 1400 inputs to 1802n from microcontroller, replace O E, polarity and the clock line of Figure 13 embodiment.Solid-state switching circuits 1804a is controlled respectively to 1802n by data line 1802a to 1804n, and with EL plate 1806 be connected to high DC Input voltage terminal or with being connected to the end.

In the work, the high level on the data line 1802a (" 1 ") value makes solid-state switch logical one 804 that its corresponding EL plate is connected to high dc voltage end, makes EL plate charging and makes it luminous.When microcontroller 1400 changed to low level (" 0 ") value to the value on the input data line 1802a, solid-state switch logical one 804a was its corresponding EL plate earthing, made its discharge and made it luminous.

On the other hand, do not use microcontroller to control the charge and discharge of EL plate 1806 independently, but adjunct circuit add to solid-state switching circuits 1804a in the 1804n to detect the variation of the value of Data Control line from the low level to the high value.When detecting this variation, solid-state switching circuits can make the high voltage pulsation that is added on the EL plate 1806 subsequently automatically.Because this carries out to 1804n automatically by on-off circuit 1804a, thus be favourable to the operator, because he needn't be concerned about that microcontroller alternately makes the programming of EL plate charge and discharge.

Figure 16 represents that one is used for by alternately switch the multi-channel transmission channel of simulating an EL plate between two plates.Switch 1700 is connected to EL plate 1702 driving powers on of two EL plates.Switch 1700 regularly switches between two plates, so that two plates are not carried out the driving of long-time section.Change action can be according to concrete application based on signal in an external timing signal, internal clock signal or the power supply.By drive signal being multiplexed on aforesaid two EL plates, a plate that drives like doubled frequency with these two EL template dies with any one separate board.Under high driving frequency, the heat of having found significantly to reduce the EL plate produces and has therefore increased the life-span of EL plate.This multi-path transmission structure can be added among aforementioned any one embodiment.

Said apparatus and method comprise the preferred embodiments of the present invention.But, under situation about not departing from the scope and spirit of the present invention, in method of the present invention or device and carry out various modifications in the structure at these embodiment and the transfer pair those skilled in the art are conspicuous.As first example, microcontroller 1400 can be used to dynamically control pressure regulator 1408.This can make microcontroller that EL plate brightness of illumination is done further control.As second example, without oscillator used among Figure 10 embodiment, power amplifier and transformer portion, as long as output stage can float according to power input, can be with a traditional inverter design scheme.Appendix A copyright 1996, Addvlaion Incorporated filename: BC9B15.SRC program function: stable for 9 unit sequence RB7=of #101-0002-00 controller
