  • METHOD FOR CAPACITIVE FINGERPRINT IDENTIFICATION, CAPACITIVE FINGERPRINT IDENTIFICATION APPARATUS AND ELECTRONIC DEVICE
    Publication number: 20220358781
    Abstract: A method for capacitive fingerprint identification. The method is applied to an electronic device with a capacitive fingerprint identification apparatus which has a special-shaped surface. The method includes: obtaining a number of driving signals N(i) of an ith column of pixel electrodes; and performing signal driving to the ith column of pixel electrodes to obtain an output voltage according to the number of driving signals N(i), the output voltage corresponds to the capacitor, and the output voltage is configured for fingerprint identification. The present application can controls a column average output voltage of the pixel electrode at a similar level, so as to facilitate algorithmic processing, at the same time, a risk of data saturation with up and down fluctuations is reduced, and thereby the performance of fingerprint identification is improved.

  • Method for managing concatenated enhanced short message and telecommunication terminal using the method
    Patent number: 7164928
    Abstract: A method for managing a concatenated Enhanced Short Message comprises the steps of creating a status variable representing the READ/UNREAD status of a page; assigning the status variable to each page received by the telecommunication terminal; initiating the assigned status variable into UNREAD; and updating the status variables of all received pages in the message into READ after any one of the received pages of the messages has been read, and updating the status variables of all the previously received pages of the message into UNREAD when a posterior page of the message is received.
