Description

The present invention relates to a touch control module having a photoelectric conversion function, and in particular, by installing the photoelectric conversion unit in the touch area of the touch control module, the light receiving area of the photoelectric conversion unit is increased and the power generation amount is increased. Thereby, it is related with the touch control module which has a photoelectric conversion function which can extend the standby time and use time of a touch control apparatus.

In a conventional general portable electronic device, power supply is the most important, and standby and use of the electronic device are realized by the power supply. The portable electronic device is powered by a built-in battery. In general, since a touch control device is used in combination with a portable electronic device, power consumption is large, and standby time and use time are greatly reduced.

In order to solve the problem of high power consumption of the conventional portable electronic device, there is a portable electronic device combined with a photovoltaic power generation module in the prior art. That is, photoelectric conversion is performed by a photovoltaic power generation module, and electric energy generated thereby is stored in a built-in battery of the portable electronic device, thereby extending the use time and standby time of the portable electronic device. Generally, a photovoltaic power generation module is installed in a non-touch area of a portable electronic device or a casing of the portable electronic device, and absorbs light and performs photoelectric conversion. For this reason, the casing needs to be made of a transparent material. Alternatively, it is necessary to project the photovoltaic power generation module outside the casing. For this reason, it has the fault that thickness reduction of a product is difficult.
