Detailed description of the invention
Existing display screen needs to show new pattern, then need to be replaced pixel arrangement, change program
Loaded down with trivial details and replacing construction is long.
To this end, the present inventor proposes a kind of bright LED screen of water, it is possible to the liquid sprayed according to user
Body and display pattern；It is thus possible to real-time response user, raising is interactive with display screen.
Understandable, below in conjunction with the accompanying drawings for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from
The specific embodiment of the present invention is described in detail.
In certain embodiments, LED display includes display surface and the back side relative with display surface；Also wrap
Including: some array LED modules, each LED module includes the LED display unit being arranged at display surface
And taps；When there being conducting liquid to be sprayed on taps, LED display unit is luminous.
Refer to Fig. 1, Fig. 1 and the circuit diagram of the bright LED display of water is shown, including: the first resistance
R1, the second resistance R2, the 3rd resistance R3, the 4th resistance R4, the 5th resistance R5, the first audion
Q1, the second audion Q2, the 3rd audion Q3, LED display unit LED, taps R6；Its
In the first audion Q1, the second audion Q2, the 3rd audion Q3 be NPN pipe, the first audion
Q1 makees on-off circuit, and the second audion Q2 and the 3rd audion Q3 is as constant-current driving.
Wherein, first end of the first resistance R1 connects power source voltage Vcc, second end of the first resistance R1
Connect first end of taps R6 and the base stage of the first triode Q1, second end of taps R6 and the
The grounded emitter of one triode Q1, the colelctor electrode of the first triode Q1 connects the of the second resistance R2
Two ends and first end of the 3rd resistance R3, the second resistance R2 first end connect power source voltage Vcc and and

Connect base stage and first end of the 5th resistance R5 of the second audion Q2, the emitter stage of the second audion Q2
Second level ground connection with the 5th resistance R5.
It should be noted that in circuit diagram, taps R6 is equivalent to resistance, there is no conductive liquid
During body conducting taps R6, taps R6 is infinitely great, and now, the first resistance R1 is operating resistance,
Ensure that the base stage of the first audion Q1 with ON operation electric current, thus can cause the 3rd audion Q3 base stage
Level be pulled low, the 3rd audion Q3 can not turn on, and therefore, does not has conducting liquid to turn at taps
Time, the negative pole of LED and the negative pole of power supply power supply be off, and LED will not be lit.
In certain embodiments, when there is no conducting liquid conducting taps R6, the first audion Q1's
Base stage can be determined by below equation with ON operation electric current:

Property, play the reference voltage of clamper.5th resistance R5 is clamper current-limiting resistance, wherein, and the 5th resistance
The resistance value of R5 is chosen according to the operating current of LED, as some embodiments, the operating current of LED
Determined by below equation:
IR5=VbeQ2/R5；
Wherein, IR5During for there being conducting liquid conducting taps R6, the operating current of LED；VbeQ2For
Second audion Q2 ground level and transmitting interstage voltage, R5 is the resistance value of the 5th resistance.
In certain embodiments, the resistance value of the 5th resistance is 15 ohm, the second audion Q2 ground level with
Transmitting interstage voltage is 0.3V, IR5=VbeQ2/ R5=0.3/15=0.02A.
In certain embodiments, the resistance value of the 4th resistance R4 can be according to Vcc and VLEDIt is adjusted.
As some embodiments, the resistance value of the 4th resistance R4 can be chosen according to below equation:
R4=(Vcc-VLED-Vbe Q2)/ILED；
Wherein, Vcc is supply voltage, VLEDKind according to LED is different and different, as some realities
Execute example, the V of reddish yellow LEDLEDFor 1.8-2.2V, the V of turquoise white LEDsLEDFor 3.0-3.5V, VbeQ2
It is the second audion Q2 ground level and transmitting interstage voltage, ILEDThe rated current normally worked for LED.
