  • Publication number: 20170200159
    Abstract: A secure payment device having first and second modes is provided. In the second mode, a payment procedure is activated to receive data of a payment member for a secure payment. The secure payment device includes a touch screen group, a payment unit, a central processing unit and a secure microprocessor unit. The touch screen group displays an operation interface and a secure payment interface. In the first mode, the operation interface receives a first operation instruction via the operation interface. In the second mode, the secure payment interface obtains the data of the payment member by the payment unit, receive the second operation instruction via the secure payment interface, and activate the payment function based on a comparing result of the authentication information and the data of the payment member. A secure payment method for the aforementioned secure payment device is also provided.

  • Publication number: 20160300539
    Abstract: A display apparatus includes a display panel, a gate driving unit and a timing control unit. The timing control unit receives an image signal composed of display data of a plurality of successive images. Each image has a standard grayscale and is composed of a plurality of sub-frames which are adjacent sequentially in time and have same display content. The sub-frames of each image include at least one first sub-frame and at least one second sub-frame. The first and the second sub-frames have different grayscales. The timing control unit further determines whether the successive images are for displaying a dynamic pattern or not. If yes, the timing control unit controls the gate driving unit to drive the display panel at a first frame update frequency, alternatively, if no, drive the display panel at a second frame update frequency, which is greater than the first frame update frequency.

  • Patent number: 7990071
    Abstract: A lamp drive circuit used for driving a number of lamps is provided. The lamps are used in a backlight module. The backlight module is used for providing a light source when a liquid crystal display displays. The lamps are respectively electrically connected to a coil. The coils have the same number of turns and have the same magnetic circuit, so that the currents flowing through the lamps are balanced.

  • Patent number: 7872424
    Abstract: A lighting apparatus comprises a plurality of light sources, a power conversion circuit, a plurality of load-driving coils and a feedback generation coil. The power conversion circuit generates a driving signal for the load-driving coils to generate substantially identical driving currents for driving every light source. Furthermore, the feedback generation coil generates a feedback signal based on the inductions of the currents flowing though the plurality of load driving coils.
