Abstract
Abstract A display unit structure for an electronic device is formed of a solar cell, and a display unit. The display unit includes a transparent base layer disposed on the solar cell, and a hologram layer laminated on the base layer and having a virtual mirror plane for reflecting a light with a predetermined wavelength. The virtual mirror plane of the hologram layer is inclined with respect to front and back surfaces of the hologram layer. Thus, the light with the predetermined wavelength is reflected by the hologram layer, and light other that the predetermined wavelength is transmitted to the solar cell.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A display unit structure for an electronic device, comprising: a solar cell, and a display unit including a transparent base layer disposed on the solar cell, and a hologram layer laminated on the base layer and having a virtual mirror plane for reflecting a light with a predetermined wavelength, said virtual mirror plane of the hologram layer being inclined with respect to front and back surfaces of the hologram layer so that the light with the predetermined wavelength is reflected by the hologram layer and light other than the predetermined wavelength is transmitted to the solar cell through the hologram layer.
Claim 2
Dependent Claim
101 words
A display unit structure for an electronic device, comprising: a solar cell, and a display unit including a transparent base layer disposed on the solar cell, and a hologram layer laminated on the base layer and having a virtual mirror plane for reflecting a light with a predetermined wavelength, said virtual mirror plane of the hologram layer being inclined with respect to front and back surfaces of the hologram layer so that the light with the predetermined wavelength is reflected by the hologram layer and light other than the predetermined wavelength is transmitted to the solar cell through the hologram layer.
