1. Technical Field
The present disclosure relates to an electronic device and a method for displaying an energy efficiency index.
2. Description of Related Art
An electronic device, such as a TV set, is labeled with an energy label. The energy label indicates a standard energy efficiency index and a standard power of the electronic device. However, the power and the energy efficiency index of the electronic device are affected by a number of operating parameters, such as a working voltage, so that the electronic device does not operate according to the standard energy efficiency index and the standard power. Therefore, the energy label can not accurately indicate the current energy efficiency index and current power of the electronic device.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the electronic device and energy efficiency indicating method thereof. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
In general, the word “module,” as used herein, refers to logic embodied in hardware or firmware, or to a collection of software instructions, written in a programming language, for example, Java, C, or assembly. One or more software instructions in the modules may be embedded in firmware, such as in an EPROM. Modules may comprise connected logic units, such as gates and flip-flops, and may comprise programmable units, such as programmable gate arrays or processors. The modules described herein may be implemented as either software and/or hardware modules and may be stored in any type of computer-readable medium or other computer storage system. Embodiments of the present disclosure will be described with reference to the drawings.

In the embodiment, the setting module 14 can be keys (not shown) of the electronic device 10, or a remote controller (not shown). In other embodiments, the setting module 14 adjusts the second parameter and the third parameter based on sensing results of different sensors.

The storage 16 stores a standard energy efficiency index, a standard total power, a standard value for the first, second, and third parameters, and a plurality of standard powers corresponding to the standard values. Table 1 below shows the relationship between the standard values and the standard powers of the first, second, and third parameters. The standard value for the first parameter is a 480 progressive scan (P) resolution for an analog formal, the standard value for the second parameter is 50 Lumens, and the standard value for the third parameter is 50 decibels (dB). The first standard power is 15 watts (W), the second standard power is 20 W, and the third standard power is 75 W.

Table 2 below shows the relationship between the values for the first parameter and the powers corresponding to the values for the first parameter. The values are resolution for a digital formal or an analog format. The resolutions include 480 P, 720P, 1080P, and 1080 interlaced scan (I).
The calculating module 17 calculates the current total power of the electronic device 10 based on the detected parameters. The calculating module 17 obtains the first current power from the storage 16 based on the detected first parameter. The calculating module 17 calculates the second and the third current power using the following equation:
P
current=(Pstandard/Vstandard)*Vcurrent
where Pcurrent is the current power of the parameter, Pstandard is the standard power of the parameter, Vcurrent is the current value of the parameter, and Vstandard is the standard value of the parameter. Then, the calculating module 17 adds the first, second, and third current powers together to obtain a current total power of the electronic device 10.
