1 is a view for explaining a portable display device according to an embodiment of the present invention.

Referring to FIG. 1, the portable display device 100 includes a power consumption calculation unit 110, a window size determination unit 130, and a display control unit 150.

The consumed power calculation unit 110 calculates an estimated amount of power consumed when a preset application program is executed. The consumed power calculation unit 110 can calculate the expected power amount based on the size of the display and the type of the application program. Here, the size of the display refers to the size of the panel mounted on the portable display device 100 in terms of hardware. Typically, the display device makes full use of the mounted panel to display a screen according to the application program in a full state or full state of the panel. Accordingly, as the size of the panel mounted on the portable display device 100 increases, the amount of power consumed may increase. Also, the type of the application program may include at least one of a DMB, a web browser, a game, and a media playback program. Illustratively, when the media playback program is executed, the amount of power consumed is larger than when the web browser is run.

The above-mentioned consumed estimated power amount can be determined by the intensity value of the RGB color inputted to the frame buffer. For example, the color of the display panel may be represented by a frame buffer. In this case, the intensity value of the RGB color input to the frame buffer may vary depending on the type of the application program. Depending on the size of the display panel, There is a difference in the amount of power consumed.

The consumed power calculation unit 110 calculates a first expected power amount consumed when an application program is displayed in a maximum window size, and when the application program is displayed in at least one window size preset to be smaller than the maximum window size, The second estimated power amount can be calculated. In addition, the consumed power calculation unit 110 can calculate the estimated power amount ratios by comparing the first expected power amount and the second estimated power amount. A detailed description will be given later.

2 is a view for explaining window sizes in a portable display device according to an embodiment of the present invention.

Referring to FIG. 2, (a) shows a case where a maximum window size is displayed on a portable display device 100, (b) shows a case where a portable display device 100 has at least one window Size is displayed. The consumed power calculation unit 110 may calculate the first expected power amount consumed in the case of (a) and calculate the second estimated power amount consumed in the case of (b). The consumed power calculation unit 110 may calculate the estimated power amount ratios by comparing the first expected power amount and the second estimated power amount.

Referring again to FIG. 1, the window size determination unit 130 determines a window size based on the estimated power amount calculated by the power consumption calculation unit 110 and the amount of power remaining in the portable display device 100. [ A detailed description will be given later.

3 is a view for explaining an example of adjusting a window size in a portable display device according to an embodiment of the present invention.

Referring to FIG. 3, (a) shows a case of displaying a maximum window size of the portable display device 100, (b) shows 85% of a maximum window size, %, And (d) is the case of 50% of the maximum window size.

The window size determination unit 130 determines a predetermined estimated amount of power amount that matches the remaining amount of power among the estimated amount of power amount calculated by comparing the first expected amount of power and the second estimated amount of power calculated by the consumed power calculation unit 110 , The window size can be determined on the basis of the result of reducing by a predetermined estimated amount of power amount determined by the maximum window size. Specifically, the expected power amount ratio can be determined by comparing the first expected power amount and the second predicted power amount, and the expected power amount ratio can be determined by comparing the estimated power amount ratio with the remaining power amount. The ratio of the predetermined estimated power amount thus determined may be a value of N%, and the value of N% may be a ratio value of reducing the maximum window size.

That is, if the N value of the N% value is determined as 50, the window size can be determined as shown in FIG. 3 (d). At this time, the window size determination unit 130 may determine the window size to a predetermined minimum window size regardless of the determined ratio, if the predetermined estimated amount of power amount is determined to be equal to or smaller than the predetermined minimum window size. That is, the window size determination unit 130 may determine the window size to be larger than a preset minimum window size. At this time, if the window size is below a predetermined level, the user may feel inconvenience because it is difficult to identify the displayed screen. Accordingly, it is possible to eliminate the inconvenience of the user by determining the window size to be larger than the preset minimum window size.

If the window size is not the maximum window size as shown in FIGS. 3 (b), 3 (c), and 3 (d), portions other than the window displayed in correspondence with the window size may be displayed in black. The area displayed in black can minimize the power value consumed by eliminating the intensity value of the RGB color input to the frame buffer. With this principle, reducing the window size can reduce the amount of power consumed.

Referring again to FIG. 1, the display control unit 150 controls the application program to be displayed in the window size determined by the window size determination unit 130 through the display. That is, since the display control unit 150 automatically controls the size of the window so that the application program is displayed at the optimal window size through the display under the present battery remaining amount condition, the user can enjoy the application program for a longer time. At this time, the user can further enlarge or reduce the window size according to necessity or preference in the state of being displayed with the optimum window size.

The portable display device 100 can determine the window size based on the remaining amount of power and the estimated amount of power consumed when the application program is executed so that the user can enjoy the application program with the optimum window size under the remaining amount of power. In addition, when the portable display device executes an application program related to watching a moving picture with a predetermined running time, the user can watch the moving picture for a maximum time with a window size determined so as not to feel uncomfortable to watch under the remaining power amount condition .

Hereinafter, a method of adjusting a window size according to an exemplary embodiment of the present invention will be described.

The method of adjusting a window size according to an embodiment of the present invention relates to a method of adjusting a window size of a portable display device 100 according to an embodiment of the present invention. The same reference numerals are applied to the components similar to those described in the portable display device 100 according to the first embodiment, and a description thereof will be simplified or omitted.

4 is a view for explaining a window size adjustment method according to an embodiment of the present invention.

Referring to FIG. 4, when a preset application program is executed, the estimated amount of power consumed is calculated (S410). Step S410 may calculate the estimated amount of power consumed by the consumed power calculation unit 110. [

Step S410 may calculate the predicted power amount based on the size of the display and the type of the application program. In addition, the step S410 may include calculating a first expected power amount consumed when the application program is displayed with the maximum window size, and if the application program is displayed with the at least one window size set to be smaller than the maximum window size, The estimated power amount can be calculated individually. In addition, in step S410, the first estimated power amount and the second estimated power amount may be compared to calculate the respective estimated power amount ratios.

Next, the window size is determined based on the estimated power amount and the remaining power amount calculated in step S410 (S420). In operation S420, the window size determination unit 130 may determine the window size.

In step S420, a predetermined estimated amount of power amount matching the remaining amount of power among the estimated amount of power amount calculated in step S410 is determined, and based on the result of reducing the estimated amount of power amount determined by the maximum window size You can determine the window size. At this time, the window size may be determined so that the window size is equal to or greater than a preset minimum window size.

Next, the application program is controlled to be displayed in the window size determined through the display (S430). The step S430 may control the display control unit 150 to display the window size.
