Abstract: The present disclosure provides a terminal device. The terminal device includes a touch display layer, a fingerprint detection layer, and a shielding layer. The touch display layer includes a touch display surface. The fingerprint detection layer is arranged on a side of the touch display layer opposite the touch display surface. The shielding layer is arranged on the side of the touch display layer opposite the touch display surface. A part of the shielding layer corresponding to the fingerprint detection layer is located on a side of the fingerprint detection layer opposite the touch display layer. The shielding layer includes an electromagnetic shielding layer connected to a grounding end of the terminal device, and at least a part of the electromagnetic shielding layer is located on the side of the fingerprint detection layer opposite the touch display layer.

Abstract: A display screen module includes a display screen and a fingerprint identification unit. The display screen includes a front display area and a side display area. The side display area at least partially covers the fingerprint identification unit, and the fingerprint identification unit is configured to obtain a fingerprint image. As the fingerprint identification unit is at least partially covered by the side display area, it can reduce or even needs not to occupy under-screen space of the front display area, and arrangement of the components can be optimized. When the user directly holds the side display area to which the fingerprint identification unit corresponds, fingerprint unlocking can be executed directly, which brings new fingerprint unlocking experience to the user, and also makes the unlocking process easier.

Abstract: Mobile payment systems and associated mobile payment methods are disclosed. A mobile payment system may include a wearable device and a mobile device wirelessly connected to the wearable device. The mobile device may transmit a payment instruction to the wearable device, which may verify whether the user's identity information is correct according to the payment instruction. If the user's identity information is correct, the wearable device may generate a payment-permitted instruction and encrypt the payment-permitted instruction by a secret key. The wearable device may transmit the encrypted payment-permitted instruction to the mobile device, which may perform decryption on the encrypted payment-permitted instruction, if the mobile device can correctly decrypt the encrypted payment-permitted instruction, the mobile device can make a payment. Thus, the present disclosure can improve the security of the payment information in mobile payment.

Abstract: The invention discloses a TF card connector which is capable of installing a Nano-SIM card and a mobile phone thereof. The TF card connector is improved by arranging a Nano-SIM card connector in the TF card connector so that the functions are increased for the TF card connector. The mobile phone have the function of installing an SIM card by arranging the TF card connector capable of installing the Nano-SIM card in the mobile phone to increase the novel functions for the mobile phone such that the Nano-SIM card is used simply and conveniently after the Nano-SIM card is installed.

Abstract: A method, a device and a mobile terminal for 3D operation control of a touch screen are disclosed. The method comprises the following steps: acquiring capacitance values of at least two acquiring points in a motion trajectory formed by a finger or a conductor moving in a touch screen sensing space; calculating coordinates of the acquiring points on the X-axis, the Y-axis and the Z-axis respectively according to the capacitance values of the acquiring points to obtain 3D coordinates of the acquiring points; and determining the motion trajectory according to the 3D coordinates of the at least two acquiring points and executing a corresponding operation. In this way, the purpose of identifying a 3D gesture can be achieved to enrich the operations of the mobile terminal.
