Abstract
The invention discloses a portable display device, which comprises a plurality of power input ends, a battery supply, an image display region, a control system and a selection system, wherein, the battery supply supplies power to the image display region through one of the power input ends; the control system judges the current remaining power of the battery supply; and the selection system provides the selectable operation time of the portable display device for a user according to the current remaining power of the battery supply. By using the technical proposal provided by the invention, the user can freely select the operation time of the portable display device as required, so as to meet the demand for reducing the energy consumption of the portable display device.
Description
Technical field
The present invention relates to a kind of power-saving technology, the particularly a kind of power-economizing method that can select working time that provides for mancarried device.
Background technology
Usually, portable display apparatus carries out work by battery, so its working time is limited.Provide many different technology to prolong the working time of portable display device in the prior art, prolonged its working time but these technology major parts are methods of taking to reduce the image quality of image that display device generates.For example, by reducing the brightness of display device, battery life can obtain prolonging, thereby be provided longer working time.
Generally speaking, portable display device when battery operated, can be set to energy-saving mode at it.But this energy-saving mode normally immobilizes, and does not allow the user to preset the working time of portable display device voluntarily.So the user lacks a kind of fast way and knows that portable display device will be out of service when, and can only only be to wait for that it quits work.Therefore, be necessary to provide a kind of user of making freely to select the portable display device system of working time.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of power-saving technology, the particularly a kind of power-economizing method that can select working time that provides for mancarried device.
A kind of portable display apparatus, it comprises some power inputs, battery supply and image display area, battery supply is the image display area power supply by one of them power input, this portable display apparatus also comprises a control system and a selective system, this control system is judged the battery supply current dump energy, and this selective system provides the working time selected of portable display apparatus for the user according to the battery supply current dump energy.
Technical scheme of the present invention makes the user can freely select the working time of portable display apparatus as required, has satisfied the demand that reduces the portable display apparatus energy consumption.
Description of drawings
Fig. 1 is the structural representation of display device of the present invention.
Embodiment
See also Fig. 1, be the synoptic diagram of display device of the present invention.In Fig. 1, display device 100 comprises some power input IN1 and IN2, and image display panel/zone 110.Wherein, one of them of power input IN1 and IN2 is the external ac power source input end, and another one is power autonomous (as battery) input end.In addition, display device 100 comprises that also other are as signal input ports (figure does not show) in order to view data to be provided such as video inputs.
In Fig. 1, when display device 100 was worked by the external AC power supply of power input input, it was in full-power mode.At this moment, because the work that AC power is actually to display device 100 provides unlimited power supply supply, so the user need not take notice of the working time of display device 100.Thereby the independent operation system of each of display device 100 as brightness, volume, color, tone, contrast etc., all can work in the optimum performance state.
But when the battery supply of display device 100 by power input input, or during inner rechargeable battery (figure does not show) work, it is in the half-power pattern.At this moment, because battery supply only can provide limited power supply supply for the work of display device 100, so the user need utilize selective system 120 to come to determine and select required working time for display device 100.This selective system 120 comprises that screen upward shows (OSD) device, is used to the user that the input and display device approach of 100 required working times is provided.For example, the user can select maximum working time for display device 100.Wherein, control system 130 can be according to the electric weight and/or the available lowest energy consumption pattern of display device 100 work of current remaining battery, judges and shows maximum available working time.Therefore, in case the user has selected required working time, control system 130 will be judged the electric weight of current remaining battery, and send appropriate control signals to display device 100, be that display device 100 provides enough power supplys to guarantee battery in the working time of selecting.
In addition, control system 130 is controlled selective system 120 with the restriction range of choice of working time also based on the current battery dump energy after judging.If control system 130 judges when the dump energy of current battery is lower than a certain specific run time range, selective system 120 will be not can for the user provide above-mentioned specific working time selected scope.For example, if judge that through control system 130 dump energy of current battery can only be supported 45 minutes, then selective system 120 will can not provide any selectable range of being longer than 45 minutes for the user.
The control signal that control system 130 is sent can be controlled the various running parameters of display device 100, as in brightness, volume, color, tone, the contrast etc. one or more.For example, if control system 130 is in 30 minute working time that the user selects, the electric weight of current battery will be not enough, and then control system 130 is sent signal brightness or volume are reduced, to guarantee in the working time of selecting image display area 110 display image continuously.
In Fig. 1, selective system 120 is also at display device 100 duration of works, and the feature operation of display device 100 is shown to the user on image display area 110.For example, shown feature operation can comprise the number percent of the excess time of selected working time, current battery dump energy or the number percent or the actual numerical value of actual numerical value and any controlled its reduction of running parameter.In addition, control system 130 also provides when watching display device 100 images for the user, prolongs the display device approach of 100 working times.It shows that by the dump energy based on current battery various information are realized on image display area 110 and/or selective system 130.For example, judge based on the working time of user's selection and the dump energy of current battery,, then have and to use longer working time if reduce the performance of some running parameter when control system 130.Then selective system 130 can show following information to the user, as " reduce volume 50% and will increase by 4 minutes ", " reduce brightness 30% and will increase by 8 minutes " etc.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
