Description
Technical field
The present invention relates to display screen technology field, a kind of mobile phone display screen backlight subarea lighting method and dress are specifically referred to
Put.
Background technology
With continuing to develop and progressive for science and technology, the function of electronic device terminal becomes increasingly complex, such as camera function, hand-written
Function, music playback function, visual telephone function, terminal TV function etc., terminal also develop into intelligent end from ordinary terminal
End.However, the function of terminal is more complicated, power consumption is also more, and the stand-by time of terminal is also just into the one of terminal fast development
Individual obstacle.
For mobile phone, most frequently power consumption is display screen, and the use ratio more and more higher of current display screen causes electricity
The endurance of sub- equipment is poor.Meanwhile, the function of current mobile phone is more and more, and mobile phone screen is also increasing, and when standby
Between require again very long, this requires the battery capacity of mobile phone than larger, however mobile phone to be done it is compact attractive in appearance, so again limit
The size of battery of mobile phone.Generally, because cell-phone function is relatively more, many battery electric quantities can be consumed, and mobile phone screen it is big, it is necessary to
Increase backlight quantity used, can be only achieved than more uniform backlight effect, therefore screen is big, the electric current flowed through on backlight
Can accordingly increase, can be only achieved to compare and clearly indicate effect.
Chinese patent CN2007102001506.9 discloses and a kind of automatically adjusts LCD brightness to save terminal electric power
Method, it judges the dark bright situation of external environment by camera, automatically adjusts the brightness of whole LCD.It is first in this method
First require that terminal there will be camera, camera is opened in addition and is accomplished by power consumption in itself, if do not stopped to obtain external environment
If opening camera, LCD portion is power saving, but the ceaselessly power consumption again of camera part, especially battery electric power it is not enough when
Wait, camera can normal work be also problem.If external environment light is darker in addition, battery electric quantity is again not enough
In the case of, if the comparing of LCD settings is bright, power consumption can be compared, accelerate the consumption of battery electric quantity.
The content of the invention
The purpose of the present invention is to overcome weak point of the prior art, there is provided lighted a kind of mobile phone display screen backlight subarea
Method, can save electricity, improve stand-by time.
The purpose of the present invention is achieved through the following technical solutions：
A kind of mobile phone display screen backlight subarea lighting method, comprises the following steps：
Step one, by the display backlight region some regions of decile, and be evenly arranged some groups in each grade subregion can
Individually to control LED backlight；
Step 2, sets a control device, and the working condition to the backlight drive circuit of LED backlight is individually controlled
System；
Step 3, controls backlight drive circuit, and the content to the backlight lightening region of display screen carries out display control, makes
LED multi-section displays.
Further, it is further comprising the steps of after the step 3：
Step 4, is covered by the peripheral regions without backlight lightening using the display content of black.
Further, it is further comprising the steps of after the step 4：
Step 5, when the user click black overlay area is detected, lights whole screen.
Based on same design, the present invention also provides a kind of mobile phone display screen backlight subarea lamp device, including：
Display screen, some backlight areas of the uniform decile of display screen；
LED backlight, it is corresponding with the backlight area quantity, and it is evenly arranged in backlight area rear；
Backlight drive circuit, it is corresponding with the LED backlight quantity, and respectively with LED backlight be electrically connected with；
Control chip, is connected with the backlight drive circuit, for closing or adjusting the posterosuperior LED back ofs the body of the display screen
Light lamp.
Specifically, mobile phone display screen backlight subarea lamp device also includes：
Opening module, is connected with control chip, backlight drive circuit, for when the non-dots for detecting user's click display screen
During bright backlight area, whole screen is lighted.
The present invention has advantages below and beneficial effect compared to existing technology：
By design, by the backlight LED light in display backlight region, subregion lights display, such as one to the present invention as needed
The display screen that 5 inch of portion by controlling the quantity of LED backlight in the middle of backlight area, it is necessary to can realize 2 inches of faces during power saving
Long-pending backlight lightening effect, so that the significantly stand-by time of extending cell phone.
Brief description of the drawings
Fig. 1 is a kind of flow chart of mobile phone display screen backlight subarea lighting method of the invention.
Fig. 2 is a kind of structural representation of mobile phone display screen backlight subarea lamp device.
Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited
In this.
Embodiment
Such as Fig. 1, the present embodiment provides a kind of mobile phone display screen backlight subarea lighting method, comprises the following steps：
Step one, by the display backlight region some regions of decile, and be evenly arranged some groups in each grade subregion can
Individually to control LED backlight；
Step 2, sets a control device, and the working condition to the backlight drive circuit of LED backlight is individually controlled
System；
Step 3, controls backlight drive circuit, and the content to the backlight lightening region of display screen carries out display control, makes
LED multi-section displays.
The above method can be realized individually controlling the working condition of LED backlight by backlight drive circuit.As now
If the original design being uniformly controlled using 12 LEDs backlights, makes can dividing for 6+6 LEDs backlights into having technology
Two groups of designs for individually controlling；When needing power saving, user can set by only allow 6 LEDs backlights to be lighted come
Power saving is realized, specific selection mode can determine according to user's needs.
By observation it can be found that user using mobile phone when in many cases (except game in addition to), be only to look at screen
A part of region, other regions do not have effective information, therefore the method that the present embodiment is provided is used in the case of power saving only
Effective coverage or key area in display screen, the technological means without showing non-key area, solve in the prior art
For mobile phone, PAD etc. without the big technical problem of the mobile terminal screen power consumption of many window interfaces, and then achieve can be to screen
