Here, household appliance can be daytime or evening according to current time, according to identical environmental light intensity data
Different matching luminance is set.With household appliance type and function it is gradually perfect, user persistently uses household appliance
It may increasingly be grown using the time, e.g., when encountering arctic weather, user may be in institute's having time outside removing sleeping time
Heating system is opened in section, in all periods of even whole day, and due to the ambient light intensity on daytime and the ring in evening
Differing greatly between the light intensity of border, the brightness value that can form appropriate level of contrast in action with environmental light intensity at daytime and evening can
Can be different, therefore can be by the quantity of the luminance grade pre-established under evening mode more than the brightness pre-established under day mode
The quantity for spending grade, so when environmental light intensity data are identical, according to day mode and the determination of environmental light intensity data and display surface
Plate corresponding first matches luminance and determines the second matching corresponding with display panel according to night mode and environmental light intensity data
Luminance can be different, and the contrast under day mode between the brightness and ambient light intensity of display panel can be higher than night mould
Contrast under formula between the brightness of display panel and ambient light intensity.When user is when the ambient light on daytime is stronger, show
Show that the brightness of panel can be higher to ensure that user can see, when household electrical appliances are set user when being in sleep period at night
The brightness of standby display panel then avoids higher since ambient light intensity is relatively strong, avoids interfering user or user
Night be in need to operate/check the display panel of household appliance when, the brightness of display panel can be softer, it is ensured that energy
Better view result is enough provided.
Optionally, the step 105 determines control parameter corresponding with the display panel according to the matching luminance,
The luminance of the display panel is adjusted according to the control parameter, the control parameter includes drive cycle and lights duration, is wrapped
It includes：

Show that panel lights duration described in lighting in the same time period of the drive cycle respectively.
In the embodiment of the present application, the adjusting of the luminance of display panel be by control panel in corresponding drive cycle point
It is bright it is corresponding light duration realization.With the quantity of luminance grade for 16, for drive cycle is 2 milliseconds, when according to environment
When light intensity data determines that the corresponding matching luminance of display panel is the first luminance grade, then a length of 125 microsecond when lighting, so as to
125 microseconds are persistently lighted in every 2 milliseconds of drive cycle to control the display panel, the display panel is accordingly made to be adjusted to
One luminance grade；When determining that the corresponding matching luminance of display panel is the second luminance grade according to environmental light intensity data, then point
A length of 250 microsecond when bright persistently lights 250 microseconds in every 2 milliseconds of drive cycle so as to control the display panel, accordingly
So that the display panel is adjusted to the second luminance grade；And so on, by adjusting display panel in each drive cycle
Light duration, the luminance of adjustable display panel.Preferably, duration is lighted needed for according to display panel in drive cycle
The size of length so that display panel lighted in the same time period of the drive cycle respectively it is described light duration, e.g., when
When the matching luminance for determining display panel is the first luminance grade, so that before display panel is in every 2 milliseconds of drive cycle
Persistently lighted in 125 microseconds or make display panel in every 2 milliseconds of drive cycle second 125 microsecond in continue
It lights, so adjacent interval of lighting is equal, avoids lighting that interval is uneven or part is too long and causes to flash, and influences to show
Show the display effect of panel.
In other optional embodiments, the quantity of luminance grade, drive cycle and in the respective drive period when lighting
Length can also change according to the difference of concrete application scene, usually need only assure that and control the display panel in different luminance etc.
When grade, adjacent lighting is no more than preset value, such as 2 milliseconds and causes to generate flashing between duration.By determining driving week
Duration is lighted in phase and corresponding drive cycle, is controlled the display panel corresponding in persistently being lighted respectively in corresponding drive cycle
The mode of duration is lighted to adjust the luminance of display panel, controls signal all the way so as to pass through using identical control parameter
Realize and control lighted to light source in display panel, relative to using pulse-width modulation PWM signal respectively to correspondence in display panel
A column light source controlled for, cost it is lower and be more convenient for realize adjust.
