Embodiment Construction

[0012] The control signal sent by the control system 130 can control various working parameters of the display device 100, such as one or more of brightness, volume, color, hue, contrast, and the like. For example, if the control system 130 will run low on the current battery during the 30-minute run time selected by the user, the control system 130 will send a signal to reduce the brightness or volume to ensure that the image display area 110 can continue to operate during the selected run time. The image is displayed continuously.

[0013] exist figure 1 Among them, the selection system 120 also displays the function operations of the display device 100 on the image display area 110 to the user during the working of the display device 100 . For example, the displayed functional operations may include the remaining time of the selected run time, the percentage or actual value of the current remaining battery charge, and the percentage or actual value reduction of any contro...

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 [0001] The invention relates to an energy-saving technology, in particular to an energy-saving method for providing optional running time for a portable device. Background technique [0002] Typically, portable display devices operate on batteries and thus have a limited runtime. Many different technologies are provided in the prior art to prolong the running time of the portable display device, but most of these technologies extend the running time by reducing the image quality of the image generated by the display device. For example, by reducing the brightness of the display device, battery life can be extended, thereby providing longer run times. [0003] Generally speaking, a portable display device is set to a power saving mode when it operates on a battery. However, the power saving mode is usually fixed, and the user is not allowed to preset the running time of the portable display device. Therefore, the user lacks a convenient way to know when th...
