Abstract
A touch-sensing keyboard including a solar cell, a touch panel, and a power converter is provided. The solar cell has a light receiving surface. The touch panel is disposed above the light receiving surface of the solar cell, wherein the solar cell receives light passing through the touch panel and converts the received light into electric power. Furthermore, the power converter is electrically connected to the solar cell and the touch panel, wherein the power converter receives and transforms the electric power generated from the solar cell and outputs the transformed electric power to the touch panel.
Claims11
A touch-sensing keyboard, comprising:
- a solar cell having a light receiving surface;
- a touch panel configured over the light receiving surface of the solar cell, wherein the solar cell receives a light passing through the touch panel and transforms the received light into an electric power;
- and
- a power converter electrically connected to the solar cell and the touch panel, wherein the power converter receives the electric power from the solar cell and transforms the received electric power, and outputs the transformed electric power to the touch panel.
The touch-sensing keyboard of claim 4, wherein the solar cell includes CdS thin film solar cell, CdTe thin film solar cell, CuInSe2 thin film solar cell, dye sensitized thin film solar cell or organic thin film solar cell.
