Description
Technical field
The utility model relates to the mobile communication technology field, particularly a kind of portable terminal with illumination functions.
Background technology
The illumination functions of mobile phone when smart mobile phone is used the illumination functions of software control mobile phone, need to provide separately the software resource of this function generally by software control.If the user opens mobile phone when illumination, need to operate mobile phone screen, the software that enters Mobile phone lighting lamp by function menu is chosen and is opened the illumination option, could open illuminating lamp.This process need wakes mobile phone up from holding state, after mobile phone was activated, power consumption began to increase.And present smart mobile phone screen is large, and when the starting hand-set illumination functions, whole screen all needs to be lit, and has reduced the stand-by time of mobile phone.After the illuminating lamp of mobile phone was opened, the screen of mobile phone was lit always, until illumination finishes.
Through test, the power consumption of whole lighting process is in the power consumption of talking state always in this process close to mobile phone.If software is not controlled well, the screen that needs mobile phone always light yellow could be to the power supply of LED lamp, if cell phone standby, the voltage signal of power management chip management control illuminating lamp power supply will disconnect, and illuminating lamp will extinguish.
Take 3.5 inches LCD screens as example, when mobile phone screen is bright, open the function of illuminating lamp, maximum if brightness of illumination is selected, lighting hours is 2 minutes, and mobile telephone power consumption is 186.4mA, and the moment maximum current of illumination just reaches 288mA; If the brightness of illumination is selected minimum, mobile telephone power consumption is 117.2mA, and the moment maximum current of illumination has 141.9mA.When mobile phone screen went out, when brightness of illumination was the brightest, mobile telephone power consumption was 106.6mA, moment maximum current be 134.4mA; Brightness of illumination hour, the power consumption of mobile phone is 42.9mA, moment maximum current be 65.1mA.When screen is bright, select the brightlyest if will throw light on, then the electric weight of mobile phone screen consumption just has 186.4mA-106.6mA=79.8mA, brightness of illumination hour, the electric weight of mobile phone screen consumption has 117.2mA-42.9mA=74.3mA.The maximum electric weight that the screen of mobile phone consumed in moment during illumination has 288mA-134.4mA=153.6mA, even in the mobile phone illumination hour, the moment power consumption of screen also has 141.9mA-65.1mA=76.8mA.As seen, mobile phone is when illumination, if light screen, no matter the brightness of illumination is the brightest or the darkest, the electric weight that mobile phone screen consumes is all very large, so light the function that mobile phone screen is realized illumination, can waste a lot of electric weight on the screen of mobile phone, moreover in when illumination, can not operating handset, so wasted the electric weight of battery.
Because the electric weight of the longer consumption of time of illumination is more, and the screen of mobile phone is larger, the electric weight that consumes during illumination is also larger.With regard to the present mobile phone of large-screen, calculate according to 4.0 cun mobile phone screens, when screen was bright, the mobile telephone power consumption that throw light on when the brightest was 464.5mA, and the mobile telephone power consumption when the darkest is 451.0mA, and therefore the electric weight of illumination consumption can be larger, and the power-on time of battery is also shorter.
Battery electric quantity with 1500mA, 3.5 the LCD of inch shields to calculate, when screen is bright, the powered battery duration of throwing light on when the brightest is: 1500mA/186.4mA=8 hour, the battery-powered time that throws light on when the darkest is: 1500mA/117.2mA=12.8 hour, and when mobile phone screen went out, the battery-powered time that throws light on when the brightest was: 1500mA/106.6mA=14 hour, the battery-powered time that throws light on when the darkest was: 1500mA/42.9mA=34.9 hour.And the mobile phone of large-screen is being lighted screen illumination, and the power-on time of battery can be shorter.
Therefore, the control mode of the illumination of existing portable terminal need to be improved.
