  • Publication number: 20190146273
    Abstract: Provided are a backlight module and a liquid crystal display device. The backlight module includes: a backlight source structure layer; and a first convex lens structure layer, a second convex lens structure layer and a prism layer that are sequentially arranged at a light-emergent side of the backlight source structure layer. The parallel lights emitted from the backlight source structure layer are converged to a focal point of the second convex lens structure layer after passing through the first convex lens structure layer, and transformed into the parallel light beam after passing through the second convex lens structure layer. The parallel lights are transformed to parallel light beam in a convergence state from an original well-distributed state. The parallel light beam is refracted for multiple times after passing through the prism layer to realize light splitting, so that lights with different colors are refracted.

  • Publication number: 20190123818
    Abstract: A cable modem (CM), a hybrid fiber coaxial (HFC) network fault locating system, and a fault detection method are provided. The CM can not only detect intrusion noise outside a carrier and white noise, but also detect other fault problems, such as non-linear distortion, pulse noise, intrusion noise on a carrier, and linear distortion. The system includes a direction-selective apparatus. The apparatus can allow only an upstream signal entered from an output port of the apparatus to be transmitted to a CM to which a branch port of the apparatus is connected, without allowing an upstream signal entered from an input port of the apparatus to be transmitted to the CM to which the branch port of the apparatus is connected, so that once detecting a fault from the upstream signal, the CM can accurately determine, through locating, that the fault in an HFC network is located on an output port side of the apparatus.

  • Patent number: 10097482
    Abstract: The present application discloses methods, devices and systems for networking communication and information display. Based on a predefined layout provided by a server, service providers may customize the predefined layout by designating/designing actionable options that may be used in the layout to generate user interfaces. Due to the dual sources of the customized interfaces, some of the actionable options in different interfaces are the same and some of the actionable options are different. A user may select an actionable option displayed at a mobile terminal, which may cause the mobile terminal to send a request to the server, receive a response from the server, and display the response. The current invention allows service providers to configure predefined layouts and present the customized interfaces to users, improving communication experiences while maintaining a level of similarity between the interfaces from different service providers.
