Embodiment
Below in embodiment, be described in detail detailed features of the present utility model and advantage, its content is enough to make any those skilled in the art to understand technology contents of the present utility model and implements according to this, and according to the disclosed content of this instructions, claim scope and accompanying drawing, any those skilled in the art can understand the utility model relevant purpose and advantage easily.Following embodiment further describes viewpoint of the present utility model, but non-to limit category of the present utility model anyways.
Please refer to Fig. 1, be the portable electronic devices calcspar of the utility model one embodiment with electricity-saving function.
As shown in Figure 1, a kind of portable electronic devices with electricity-saving function comprises liquid crystal panel 100, microprocessing unit 110, power supply unit 120 and voltage detection unit 130.
Wherein, when voltage detection unit 130 detects electric energy that power supply unit 120 stores and is lower than ratings, microprocessing unit 110 will dwindle image that liquid crystal face version 100 shows and image will be shown in the viewing area of part, save electric energy for this reason and prolong up time of portable electronic devices.
At this, ratings is the benchmark of an electric energy current potential of presetting, and is higher than the electric energy abundance that the ratings interval scale stores, and is lower than the electric energy deficiency that ratings Shi Ze representative stores, and therefore need start electricity-saving function.
Illustrate, as a portable electronic devices (for example: digital camera), (for example: battery) stored electric energy is limited for power supply unit 120, when voltage detection unit 130 detects power supply unit 120 stored electric energy and is lower than a ratings, microprocessing unit 110 will dwindle image that the liquid crystal panel 100 of portable electronic devices shows and the viewing area that image is shown in part, therefore that is the image that dwindles only is shown on the liquid crystal panel 100 of part, can save electric energy.
Please refer to Fig. 2 A and Fig. 2 B, Fig. 2 A is the portable electronic devices calcspar with electricity-saving function of the utility model one embodiment.Fig. 2 B is the backlight module synoptic diagram of the utility model one embodiment.
Shown in Fig. 2 A, wherein also comprise a backlight module 140.Backlight module 140 comprises a plurality of light guide plate 141 and a plurality of light emitting sources 142.Light emitting source 142 is electrically connected at power supply unit 120 and microprocessing unit 110.
Shown in Fig. 2 B, a plurality of light guide plate 141 are arranged each other, but its leaded light makes liquid crystal panel 100 be able to show image in liquid crystal panel 100.Light emitting source 142 provides backlight corresponding to light guide plate 141 and luminous in light guide plate 141.
When voltage detection unit 130 detects power supply unit 120 stored electric energy and is lower than ratings, microprocessing unit 110 will be closed corresponding to the light emitting source 142 of the viewing area of the liquid crystal panel 100 of show image not, can save electric energy partly.
At this, light guide plate 141 and light emitting source 142 optionally use modes backlight such as the illuminated or straight-down negative of side, and so it only is an exemplary illustration, and is non-in order to limit enforcement aspect of the present utility model.
Illustrate, (for example: (for example: battery) stored electric energy is limited for power supply unit 120 digital camera) as a portable electronic devices, when voltage detection unit 130 detects power supply unit 120 stored electric energy and is lower than a ratings, voltage detection unit 130 will send power save signal to microprocessing unit 110, microprocessing unit 110 receives the shown image of the liquid crystal panel 100 that will dwindle portable electronic devices after the power save signal and image is shown in the viewing area of part, that is the image that dwindles only is shown on the liquid crystal panel 100 of part, and will close corresponding to the light emitting source 142 of the viewing area of the liquid crystal panel 100 of show image not, to save electric energy.
At this, light emitting source 142 is optionally selected light emitting diode for use.
Please refer to Fig. 3, be the portable electronic devices calcspar of the utility model one embodiment with electricity-saving function.
Wherein, comprise that also one switches switch 150.Change-over switch 150 is electrically connected at microprocessing unit 110.
The user can manually control microprocessing unit 110 by change-over switch 150 and dwindle the shown image of liquid crystal panel 100, and this image is shown in the viewing area of part and closes corresponding to the light emitting source 142 of the viewing area of show image not.
In addition, also comprise a storage element 160.Storage element 160 is electrically connected at microprocessing unit 110.Storage element 160 stores the ratings of default electric energy current potential, and 130 of voltage detection units ratings according to this are the benchmark of store electrical energy.
Please refer to Fig. 4 A and Fig. 4 B, be the portable electronic devices synoptic diagram of the utility model one embodiment with electricity-saving function.
Shown in Fig. 4 A, for when power supply unit 120 stored electric energy are higher than ratings, represent the electric energy abundance, so all viewing areas of liquid crystal panel 100 will show the image of full-size.Shown in Fig. 4 B, for when power supply unit 120 stored electric energy are lower than ratings, represent the electric energy deficiency, will only have only partly viewing area show image this moment, and this image will be via being shown in liquid crystal panel 100 after microprocessing unit 110 minifications.
Below be described further for example, for example, portable electronic devices is as a digital camera, and it has a liquid crystal panel 100 and shows the image of taking.When power supply unit 120 (as: battery) is detected stored electric energy and is lower than the ratings of default electric energy current potential in the storage element 160 by inner voltage detection unit 130, microprocessing unit 110 will dwindle this image and will dwindle after image be shown in the part viewing area of liquid crystal panel 100, also will close corresponding to the light emitting source 142 of the viewing area of show image not in the backlight module 140, therefore backlight module 140 partial action is only saved electric energy.On the other hand, the user also can be by change-over switch 150 (for example: a button) manually control the startup of electricity-saving function, when the user starts electricity-saving function by change-over switch 150, change-over switch 150 will be sent power save signal to microprocessing unit 110, microprocessing unit 110 will dwindle the image that liquid crystal panel 100 shows and will dwindle after image be shown in the part viewing area of liquid crystal panel 100, also will close corresponding to the light emitting source 142 of the viewing area of show image not in the backlight module 140, therefore reach power saving and prolong up time of portable electronic equipment.
In sum, portable electronic devices with electricity-saving function of the present utility model detects electric energy by voltage detection unit 130, when electric energy is lower than ratings, microprocessing unit 110 will dwindle image and image will be shown in the viewing area of part, and close light emitting source 142 corresponding to the viewing area of show image not to save electric energy, therefore solved prior art problems.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
