  • Publication number: 20220374889
    Abstract: A virtual payment method and system. A first virtual account is associated with a physical account, and a second virtual account is associated with the physical account. That is, virtual accounts of different accounts are all associated with the physical account. During the payment for flight ticket booking information by means of virtual payment, it is an exchange of a virtual currency between different virtual accounts associated with the same physical account. During the process, balances in virtual accounts that exchange virtual currencies with each other change, but the total amount in the physical account associated with a plurality of different virtual accounts remains unchanged, that is, the actual currency amount in the physical account does not change. The present invention would not he restricted by an implementation measure of the Central Bank.

  • Patent number: 9411193
    Abstract: The present invention relates to a backlight module for providing light to a liquid crystal panel and a display device. The backlight module comprises an optical membrane material arranged at a back surface of the liquid crystal panel, and a module frame surrounding the optical membrane material. An end surface of the module frame facing the liquid crystal panel is located at the back surface of the liquid crystal panel, and the module frame supports the liquid crystal panel through the end surface. The display device comprises a liquid crystal panel and the backlight module. According to the present invention, the end surface of the module frame facing the liquid crystal panel is located at the back surface of the liquid crystal panel. As a result, it is able to provide a very narrow end surface of the module frame, thereby to narrow a bezel of the display device.
