1. Technical Field
The present disclosure relates to an information input module and an electronic device using the same.
2. Description of Related Art
With the progress of science and technology, new materials for converting light energy to electrical energy are developed and energy conversion efficiencies of the new materials have been significantly improved. The new materials are applied on top surfaces of electronic devices to collect solar energy and/or ambient light energy for converting the solar energy and/or ambient light energy to electrical energy. The new materials are mounted at different isolated areas of the top surface. When an area is shielded by the user for operating on the electronic device, the energy conversion efficiency of the area is reduced. However, the area shielded by the user is idle and not sufficiently used since it cannot collect solar energy and/or ambient energy when being shielded.
Therefore, what is needed is an information input module and an electronic device using the same to alleviate the limitations described above.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of an information input module and an electronic device using the same. Moreover, in the drawings, like reference numerals designate corresponding sections throughout the several views.

The transparent substrate 101 is made up of glass material or plastic material with good light transmittance.
The solar cell layer 103 is disposed between the transparent substrate 101 and the protection layer 105. The solar cell layer 103 includes a number of solar cells 6 electrically insulated from each other, and an isolating area 7 configured for isolating the solar cells 6 from each other. Each of the solar cells 6 corresponds to at least one control command for activating at least one function of the electronic device 100 (See
In the embodiment, the solar cells 6 are made up of materials such as amorphous silicon, monocrystalline silicon, polycrystalline silicon, or organic silicon, and are coated and lattice shaped on the transparent substrate 101 via industrial coating technology. A plurality of command characters are allocated correspondingly on the solar cells 6 and are etched on the portions of the light incident surface of the transparent substrate 101 respectively with a laser.
Both the first and second electrodes 102, 104 are electrically connected to the solar cells 6. In the embodiment, both the first and second electrodes 102, 104 are layered, and the solar cell layer 103 is disposed between the first and second electrodes 102, 104.
The first electrode 102 is disposed between the transparent substrate 101 and the solar cell layer 103. The first electrode 102 is made up of transparent conductive materials such as indium tin oxide (ITO) film, and electrically connected to one terminal of each of the solar cells 6 to serve as the common electrode of the solar cells 6.
The second electrode 104 includes a number of conductive electrodes 8 and an insulating area 9 configured for electrically isolating the number of conductive electrodes 8 from each other. The conductive electrodes 8 are electrically connected to the other terminals of the solar cells 6 correspondingly, and transmit the electrical parameters of the solar cells 6 to the electronic device 100 via connection to the external wires by at least one conductive column 3.
The protection layer 105 is configured for fixing the first electrode 102, the solar cell layer 103 and the second electrode 104 on the transparent subtract 101.
With such configuration, when an area of the transparent substrate 101 is shielded, the solar light beams and/or ambient light beams are blocked from reaching on, wholly or partially, the solar cell 6 corresponding to the shielded area, thus the voltage, the current, the energy conversion efficiency and other electrical parameters of the solar cell 6 change accordingly. The electronic device 100 outputs control commands corresponding to the changes of the electrical parameters of the solar cell 6 to the corresponding function. Thus, the solar cell 6 is used also used as an input unit.

The processor 12 compares the electrical parameters of the solar cells 6, and executes the control command of the solar cell 6 which has the lowest electrical parameter value. In the embodiment, the processor 12 only compares the electrical parameters of the solar cells 6 whose electrical parameters have changed, which reduces the burden on the processor 12 and speeds up the response to the operation of the user.
In an alternative embodiment, the processor 12 stores a plurality of control commands corresponding to the conditions that the electrical parameters of at least two of the solar cells 6 change at a same time. The processor 12 retrieves the corresponding control command, when the electrical parameters of at least two solar cells 6 change at a same time, and executes the control command, thus achieving a multi touch function. The processor 12 executes the control command correspondingly to the solar cell 6 which has the lowest electrical parameter value or ignores the operation, when no control command is stored to correspond to the condition that the electrical parameters of the at least two solar cells 6 change at a same time.
The electronic device 100 includes the information input module 10 with converting light energy to electrical energy function, thus sufficiently uses the solar light and/or ambient light, and achieves an additional information input function.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
