Abstract

Disclosed is a liquid crystal display (LCD) module with solar cell. The problem that the mobile PC with LCD module consumes much energy in spite of no power supply is solved by solar cell in LCD mudule. In other words, the mobile PC with solar cell can work for longer time without power supply (except a battery) and charge a battery . Therefore, this invention will contribute to saving power consumption of mobile PC and LCD monitor.

Solar cell in LCD module

Disclosed is a liquid crystal display (LCD) module with solar cell.
The problem that the mobile PC with LCD module consumes much energy
in spite of no power supply is solved by solar cell in LCD mudule.
In other words, the mobile PC with solar cell can work for longer
time without power supply (except a battery) and charge a battery .
Therefore, this invention will contribute to saving power
consumption of mobile PC and LCD monitor.

The figures show examples of this LCD cell or module. Figure.1-A
shows normal LCD cell. Light must not be transmitted at the area
of black matrix (4), so this area is usable for solar cell.
Figure.1-B shows LCD module of which the black matrix consists of
solar cell (5) between color filters (2). Figure.1-C shows that
solar cell (7) is on the outside of glass (1) of the area of the
black matrix. Figure.2 shows that solar cell module is on the
outside of reflecting LCD module.
