Embodiment 1

[0027] As the first embodiment of the present invention, the method provided by this application specifically includes the following steps:

[0028] Step 1: First select the corresponding LCD projection device to be analyzed;

[0029] Step 2: Data interception is performed on the LCD projection device corresponding to the user's usage habits. The specific method of data interception is as follows:

[0030] S1: mark the LCD projection as the target device;

[0031] S2: Divide the time period, divide the day into 24 standard time periods, the standard time period starts from zero, and the first time period is from zero to one point, and so on to get all the standard time periods;

[0032] S3: Obtain the usage times and segment usage ratio of the target device in each period;

[0033] The number of times of use refers to the time when the target device is stopped after being used. If it is not used again after T1 time, the value of the number of times of use is automatically in...

Embodiment 2

[0077] As the second embodiment of the present invention, when the present application is specifically implemented, compared with the first embodiment, the only difference is that in this embodiment, T4 is 8 minutes, T3 is 5 minutes, and T2 is 3 minutes;

[0078] Example 1 and Example 2 were randomly distributed in several experiments for half a year, and corresponding sample data were collected. The sample data included the evaluation score and the average power consumption of a single day. The evaluation score was the average of the specific scores given by the experience user. After comparing the two data, the following conclusions are drawn:

[0079] Example 1 Embodiment 2 Evaluation points 87% 115% Average power consumption 125% 80%

[0080] The data in the table means that the evaluation of Example 1 is divided into 87% of the evaluation points of Example 2, and the evaluation of Example 2 is divided into 115% of the evaluation points of E...

Embodiment 3

[0082] In the specific implementation, the difference between the specific implementation provided by it and the first example is only that one day is divided into 24 standard time periods, and it is modified that one day is divided into 48 time periods, and every half hour is a standard time period, which also starts from zero. ;
