Example, it is necessary to explanation, the step of the flow of accompanying drawing is illustrated can such as one group computer executable instructions calculating
Performed in machine system, and, although show logical order in flow charts, but in some cases, can with different from
Order herein performs shown or described step.
According to embodiments of the present invention there is provided a kind of control method of household electrical appliance display, below to present invention implementation
The control method for the household electrical appliance display that example is provided does specific introduction：
Fig. 1 is the flow chart of the control method of household electrical appliance display according to embodiments of the present invention, as shown in figure 1, should
Method includes steps S102 to step S106：
S102：Judge whether to receive trigger command, wherein, trigger command is lighted for trigger scope, i.e. triggering life
Make for controlling display to open illumination functions, the trigger command can be issued by the remote control of household electrical appliance, can also led to
The guidance panel for crossing household electrical appliance is issued.
S104：In the case where judging to receive trigger command, the drive circuit of transmission Regulate signal to display, its
In, Regulate signal is used for the output signal for adjusting drive circuit, and output signal is used for the brightness for controlling display, wherein, driving
The output signal of circuit is generally voltage signal.
S106：The brightness value for controlling display is the corresponding brightness value of output signal, i.e. control display is believed according to output
Number corresponding brightness value is illuminated.
The control method of the household electrical appliance display of the embodiment of the present invention, by driving display to light, and sends regulation
Signal adjusts the brightness of display to the drive circuit of display, realize by the use of the display of household electrical appliance as light source come
Illumination functions are performed, the function of display on household electrical appliance is expanded, solves display on household electrical appliance in the prior art
The problem of illumination functions are relatively simple, and then reached the effect of abundant household electrical appliance display function.Also, the present invention is carried
The scheme that the display by the use of household electrical appliance of confession is illuminated as light source, individually buys mini light night without user, reaches again
Cost-effective effect, while it is not necessary to additionally take socket, having reached the effect for improving convenience.
Specifically, display includes LED, i.e. display can be light-emitting diode display or the liquid with LED backlight
Crystal display, drive circuit includes the anode driving circuit and negative electrode drive circuit being connected with LED, wherein, negative electrode driving electricity
The output signal on road is pulse-width signal, or the output signal of anode driving circuit is pulse-width signal, in step S104
Send Regulate signal to the drive circuit of display and be mainly transmission Regulate signal to negative electrode drive circuit or anode driving circuit,
With the dutycycle of adjusting pulsewidth modulated signal.Fig. 2 is the electricity of the display of the control method provided using the embodiment of the present invention
Lu Tu, illustrates the dutycycle by adjusting pulsewidth modulated signal to display by taking the display shown in Fig. 2 as an example below
The regulation of brightness, Fig. 3 is the physical circuit figure of MCU in Fig. 2.
As shown in Fig. 2 the negative electrode drive circuit of display is driven using IC2003, the negative electrode drive circuit passes through bus W1
It is connected with MCU, anode driving circuit is driven using IC KID, the anode driving circuit is connected by bus W2 with MCU, schemes
Diagrammatically illustrated in 2 by 4 road anodes（S1 to S4）With 7 road negative electrodes（A to G）The matrix-scanning-type drive circuit of composition, altogether
With 4*7=28 gcp logic.For single led lamp, this LED is high level in its anode, and negative electrode is low electricity
Usually light, by taking cathodic scan as an example, if negative electrode A~G exports low level in turn according to some cycles, then S1~S4 electricity
Level state determines that those current LEDs are bright, and which LED is gone out, for example：When A is low level, if S1~S4 state 1001,
The LED for being then now placed in negative electrode A and anode S1, S4 crossbar logic point is bright, positioned at negative electrode A and anode S2, S3 crossbar logic point
LED go out.Therefore, in the present invention, by the way that the output signal of negative electrode drive circuit is changed into PWM（Pulsewidth modulation, Pulse-
Width Modulation, abbreviation PWM）Signal, by adjusting high level and low level duty in pwm signal each cycle
Than, you can to realize the regulation to LED brightness, wherein, the more wide then brightness of each cycle low level is higher.Fig. 4 a schematically show
The oscillogram for the pulse-width signal that Regulate signal is adjusted is gone out, Fig. 4 b are the enlarged drawing of S portion in Fig. 4 a.
Fig. 5 is the flow chart of the control method of household electrical appliance display according to the preferred embodiment of the invention, such as Fig. 5 institutes
Show, the control method of the household electrical appliance display of the preferred embodiment mainly comprises the following steps S501 to step S507：
S501：Judge whether opening display illumination functions, i.e. judge whether to receive trigger command with step S102,
It is on the contrary if receiving trigger command, it is determined that opening display illumination functions, it is determined that non-opening display illumination functions,
Wherein, trigger command is used for trigger scope, i.e. trigger command is used to control display to open illumination functions.
S502：Judge open illumination functions duration whether be less than the first preset duration, wherein, open illumination functions when
Length is interval duration at the time of receiving trigger command between current time calculated, in embodiments of the present invention,
One preset duration can be set as 10S clock durations.
S503：In the case where judging that interval duration is less than the first preset duration, Regulate signal is sent to drive circuit,
Specifically, including step S503a and S503b, S503a：The increased Regulate signal of brightness is sent to drive circuit, is swept for negative electrode
For the drive circuit for retouching mode, the increased Regulate signal of brightness make it that low level broadens in output signal.Specifically, Yong Huke
To issue the increased Regulate signal of brightness by the "+" button on the "+" button or guidance panel on household electrical appliance remote controller；
S503b：The Regulate signal of luminance-reduction is sent to drive circuit, for the drive circuit of cathodic scan mode, brightness drop
