Abstract: A display substrate, including: a base substrate including at least a side edge and a display area; a plurality of pixel units disposed in the display area, a second pixel unit is located on a side of a first pixel unit close to the side edge, edges of the second pixel unit include the side edge, a third pixel unit is located between the first pixel unit and the second pixel unit, and the third pixel unit is adjacent to the second pixel unit; and a plurality of light emitting diode chips disposed on the base substrate a first light emitting diode chip is located in the first pixel unit, a part of a second light emitting diode chip is located in the second pixel unit, and the other part of the second light emitting diode chip is located in the third pixel unit.

Abstract: Disclosed is a novel telecommunications network architecture employing an application layer, a call control layer and a transport layer composed of seamlessly integrated Key Network Components. Additional applications such as billing on the Web Portal may be added or modified without affecting the call control layer which may be a Softswitch or Integrated SIP device. The transport or infrastructure layer acts as a media gateway and can be migrated to new platforms without affecting the call control layer or application layer. The network is of an open architecture and various features can be added to the network as required. The network can be distributed with the call control layer separated from the transport layer to provide efficiencies or redundancies within the public communication network. A configurator function automatically installs new devices or services at the request of a customer. A traffic management engine routes called based on quality of service.
