Problems solved by technology

[0008] In the case of a head-mounted display, since it is installed and used on the user's head or face, the position where the power generating device is installed is limited from a design point of view
In addition, assuming that the user moves together with the installed head-mounted display, there is a concern that the amount of power generation may change significantly according to environmental changes, that is, the power generation device may not supply power stably

[0134] First, a method of arranging power generating elements without causing damage to the design will be described as a first embodiment.

[0135] Figure 9 An example of the arrangement of power generating elements in the transmissive head-mounted image display device 100 is shown. basically, in Figure 9 In the example shown in , the power generating element may be attached to the entire outer surface of the image display device 100 . However, in consideration of not destroying the function (ie, light emission) of the image display device 100 and the design of the main body of the device 100 and ensuring power generation efficiency, various types of power generation elements employing different power generation methods are used.

[0136] As the first power generation element 901, an ultraviolet solar cell or an infrared solar cell is provided so as to transmit visible light, and power generation is performed at the central portion of the display unit front surface 601 us...

[0140] Next, a method of arranging power generating elements according to intended use will be described as a second embodiment.

[0141] Even when the above cells are the same solar cells, ultraviolet cells can perform excellent power generation using ultraviolet light, infrared cells can also perform excellent power generation using infrared light, and dye-sensitized solar cells can also perform using indoor light Excellent power generation, and silicon-based solar cells can also perform excellent power generation using outdoor light (sun light). Therefore, if Figure 7 As shown, the superiority and inferiority of the power generation amount of the power generation element of each power generation method varies depending on the power generation environment such as the installation location, the light source used, the weather, the season, and the time of day (as described above). That is, according to the power generation environment, the power generation time of the day (th...

[0147] Next, a method of dividing the main power supply of the image display device 100 into a plurality of systems according to the system operation to arrange power generation elements employing different power generation methods for each system according to the system operation will be described as a third embodiment.

[0148] Based on the assumptions of the power generation environment including place: indoor place, light source: indoor light, weather: not considered, time period: all year round, time: daytime, the time of power generation in a day (the amount of power generation is greater than the threshold (e.g., system operation level) time) in order of length: Dye-sensitized solar cells>Si-based solar cells>Infrared solar cells>UV solar cells. In addition, the amount of power generation (cumulative electric power [J, Wh]) for one day is ordered by size: silicon-based solar cells>dye-sensitized solar cells>infrared solar cells>ultraviolet solar cells (as described above...

Abstract

An image display device includes an image display unit that displays an image, a mounting unit that is adapted to mount the image display unit on a user's head or face, a power generation element that is attached to one or more installation portions including an outer surface of the image display unit or the mounting unit, and a control unit that performs control based on a power generation amount of the power generation element.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of a prior Japanese patent application JP2013-053740 filed on March 15, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present technology relates to an image display device and an image display method that are installed and used on a user's head or face, and in particular, relates to a head or face-mounted image display device and an image display method with a power generation function. Background technique [0004] Small information devices such as mobile phones (for example, smart phones), tablet terminals, e-book readers, and handheld music players that can be taken outdoors by users are being widely used. In recent years, image display devices (ie, head-mounted displays) that are mounted on the head or face and used to view images are also widely used. [0005] The head-mounted display has, for example, an image display uni...
