摘要:
A portable electronic apparatus and a method for controlling a light source thereof are provided. The portable electronic apparatus comprises a main control module, a light control module, and a light source module which is configured to generate light. The method comprises the following steps: storing a plurality of light control parameters into the main control module; outputting one of the light control parameters to the light control module by the main control module in response to an input signal; and generating and transmitting a light control signal to the light source module through the light control module in response to the outputted light control parameters. As a result, the brightness of the light generated by the light source module is controlled.
摘要:
A capacitive touch panel and operating and fabrication methods thereof. The capacitive touch panel has a plurality of transmitter electrodes and a plurality of receiver electrodes. An electric field is formed by the receiver electrodes and the powered one of the transmitter electrodes. The changes, caused by the touch of a user, in the electric field are used in touch recognition. The receiver electrodes are all in a fork shape. For one receiver electrode, the teeth are spaced in a first distance. Note that adjacent teeth from different and adjacent electrodes are spaced apart by another distance. The second distance is greater than the first distance.
