Abstract
The utility model provides a key ring, comprising a shell provided with solar cells inside, an LCD control circuit connected with the solar cells and an LCD connected with the LCD control circuit. The utility model supplies power through a solar panel and the LCD control circuit drives the LCD to flash light.
Description
(1) technical field
The utility model relates to a kind of key chain.
(2) background technology
Key chain is a kind of traditional product, mainly be key commonly used is tied up on one's body, use easily at any time.But existing key-ring does not have flash function, can't tell key in dim environment.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing key chain, the utility model provides the glistened key chain of a kind of LCD of having.
The technical scheme in the invention for solving the technical problem is: a kind of key chain comprises housing, the LCD that be provided with solar cell, the LCD control circuit that is connected with described solar cell in the described housing, is connected with described LCD control circuit.
Further, described solar cell is a non-crystal silicon solar cell, and this non-crystal silicon solar cell comprises glass substrate, transparent conductive film layer, amorphous silicon layer, the dorsum electrode layer of stack successively, and described glass substrate constitutes the rear board of described housing.
Further, described non-crystal silicon solar cell is connected by electroplating metal wire with described LCD control circuit.
Further, described transparent conductive film layer, amorphous silicon layer, dorsum electrode layer are divided into plural rectangle by the groove of equal number, and each layer groove staggers about respectively, and described transparent conductive film layer is covered by described non-silicon layer.
Further, described housing is the acryl plastics.
The utility model provides electric weight by solar panel, and it is shinny to drive the LCD flicker by the LCD control circuit.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of key chain comprises acryl housing 1, is provided with solar cell 2, the LCD control circuit 3 that is connected with described solar cell 2 in the described acryl housing 1, is connected 3 LCD4 with described LCD control circuit.Described solar cell 2 is selected non-crystal silicon solar cell for use, and this non-crystal silicon solar cell comprises glass substrate, transparent conductive film layer, amorphous silicon layer, the dorsum electrode layer of stack successively, and described glass substrate constitutes the rear board of described housing 1.Described non-crystal silicon solar cell 2 and described LCD control circuit 3 are connected by electroplating metal wire.The utility model provides electric weight by solar panel, and it is shinny to drive the LCD4 flicker by LCD control circuit 3.
As further improvement of the utility model, it is 95219353.1 the described structure of Chinese utility model patent that non-crystal silicon solar cell of the present utility model has as the patent No.: transparent conductive film layer, amorphous silicon layer, dorsum electrode layer is divided into plural rectangle by the groove of equal number, each layer groove staggers about respectively, described transparent conductive film layer is covered by described non-silicon layer, such non-crystal silicon solar cell forms some battery cascaded structures, therefore can directly produce required output voltage, because nesa coating is covered by amorphous silicon layer, both positive and negative polarity short circuit and leaky have been eliminated again.
