Method, it is possible to utilize the change under the temperature-detecting device different temperatures of electronic product to judge the temperature of its mainboard, then pass through
The difference of the temperature of its mainboard adjusts the size of screen display brightness when its display screen is lighted, thus when mainboard temperature is too high
Reduce its brightness of display screen, reduce its heat produced because display screen lights, reduce electronic product and light at display screen
Time complete machine temperature, extend the service life of its electronic product and the life safety of its user, there is bigger practical value.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
Should be appreciated that used herein such as " have ", " comprising " and " including " term do not allot one or many
Other element individual or the existence of a combination thereof or interpolation.
The invention provides a kind of electronic product method for controlling heat step to include:
1) by the real-time temperature values on temperature-detecting device detection electronic product mainboard；
2) real-time temperature values step 1 detected compares with the temperature threshold prestored in memory；
3) comparative result obtained according to step 2 adjusts the brightness of electronic product display screen.
The described temperature threshold prestored in memory is T1、T2... Tn, temperature-detecting device detection electronic product master
Real-time temperature values on plate is TiIf, Ti＜ T1, brightness of display screen is current brightness L；If T1≤Ti＜ T2, display screen is bright
Degree is L1；If Tn-1≤Ti＜ Tn, brightness of display screen is Ln-1, and Ln-1＜ L1＜ L；If Tn≤Ti, display screen is in extinguishing shape
State, successively iterative cycles above-mentioned steps.If described electronic product is in the state that display screen is lighted at the very start, then between
The temperature value of the most described electronic product mainboard is detected every certain time.If described electronic product is in display screen at the very start
Time under the state extinguished, separated in time detects whether the most described electronic product lights display screen.Deposit in memory
Storage automatically wakens up maximum duration value Smax of display screen, SiFor the distance time interval that last time, display screen was lighted.If Tn≤Ti,
Display screen is OFF state, temperature-detecting device continue detection electronic product mainboard on real-time temperature values be pre-stored in memorizer
In high temperature section temperature value compare, work as Ti＜ Tn, and SiDuring ＜ Smax, then display screen recovers brightness is L, continues cycling through
Described step 1～3, works as Ti＜ Tn, and SiDuring >=Smax, then electronic product enters deep sleep, successively on iterative cycles
State step.Described temperature-detecting device is thermo-sensitive resistor.
Embodiment 1
User can show according to several temperature thresholds of the property settings of different electronic products and the current of its correspondence
Display screen brightness value size, such as sets five temperature thresholds T1, T2, T3, T4, T5, described T1, and T2, T3, T4, T5 are respectively
45 °, 50 °, 55 °, 60 °, 65 °.The currently displaying screen brightness value size of its correspondence is respectively L*80%, L*60%, L*40%, L*
20%, 0.Described L is the present intensity of display screen, as described in chart 1.Then this value is stored in the memorizer of this electronic product
In, set time interval T, such as a 1s, or 5s etc., then this value also is stored in the memorizer of this electronic product.
If electronic product is in the state that display screen is lighted at the very start, goes to detect primary electron at interval of a time T and produce
Temperature level Ti of the mainboard of product, if electronic product is in the state that display screen extinguishes at the very start, at interval of one
Time T goes to detect whether primary electron product lights display screen.It addition, one display screen of setting reaches T5 due to mainboard temperature
After, automatic distinguishing, it is allowed to its mainboard temperature automatically wakens up maximum duration Smax of display screen after declining, this value is also stored simultaneously
In the memorizer of this electronic product.
Table 1
As it is shown in figure 1, once user begins to use electronic product, electronic product itself determines whether that being in display screen lights shape
State, if not keeping current state, waking up display screen up makes it light then to go detection to determine whether after T interval time again,
Circulate successively.If detection of electrons is in illuminating state to display screen, then be allowed to read current brightness of display screen value size
Being designated as L, next proceed to read current temperature level Ti of mainboard, before then transferring, user sets and is stored in this electricity
Five high-temperature temperatures cut-off point T1, T2, T3, T4, T5 in sub-product memorizer, then compare the size between Ti and T1, as
Really Ti ＜ T1, then keep currently displaying screen brightness value size L, and interval time goes to detect Current Temperatures after T again, the most repeatedly follows
Ring；If Ti >=T1, then continue to compare the size of Ti Yu T2, if Ti is ＜ T2, then adjust currently displaying screen brightness value size extremely
L*80%, and go again to detect Current Temperatures, successively iterative cycles after T interval time；Final according to rule, until during Ti >=T5,
Electronic product display screen extinguishes, and interval time goes to detect Current Temperatures Ti after T again, and before again transferring, user sets and storage
In this electronic product memorizer extinguish display screen time temperature value T5, compare the size of Ti Yu T5, if Ti >=T5, then continue
Display screen OFF state is held in continuation of insurance, starts again at above-mentioned circulation, until mainboard Current Temperatures Ti ＜ T5, computed range display last time
Shield bright time interval Si, and transfer to be stored in the memorizer of this electronic product simultaneously and allow to automatically waken up the longest of display screen
Time value Smax, compares size between the two, if Si >=Smax, then electronic product enters deep sleep, if Si is ＜
Smax, then light display screen, and by its brightness adjustment to L, starts again at above-mentioned circulation.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
