An optical touch detection circuit and an optical touch display panel are provided. The optical touch detection circuit includes a photosensitive module and a detection module. The photosensitive module is configured to generate a photoelectric signal. The detection module is connected to the photosensitive module. The detection module is configured to implement an optical touch function based on the photoelectric signal. The provided optical touch detection circuit and optical touch display panel can improve a signal-to-noise ratio of the optical touch detection circuit. This is beneficial for accurately determining a position of an optical touch.

A call processing method comprises: a network device receives a call request message sent by an originating UE, determines, according to the call request message, that the originating UE supports a resource reservation procedure, and further transmits, to a media server, indication information indicating that use of the resource reservation procedure for negotiation about first media is not supported and use of the resource reservation procedure for negotiation about second media is supported, so that negotiation about the second media is implemented by using the resource reservation procedure.

Call processing method and system and related apparatus

A liquid crystal alignment material and a display panel containing the same are provided. The liquid crystal alignment material includes an additive and pillar[n]arene. The additive includes a first group, a second group, and a third group. The second group is attached between the first group and the third group. The third group has a polarity. The pillar[n]arene includes n benzene rings and n is a positive integer. The benzene rings are bonded to each other and define a cavity. The pillar[n]arene is attached to the first group of the additive. The display panel includes the liquid crystal alignment material and a liquid crystal molecule.

A display panel and a display device are provided. In the display panel, an upconversion material layer is configured to convert interactive light from a first wave band into a second wave band. A light-sensing transistor of a light-sensing circuit is configured to convert a light intensity signal of the interactive light into an electrical signal after the wave band of the interactive light is converted. A position-detecting circuit is configured to identify a position where the interactive light is irradiated according to the electrical signal. Therefore, the display panel can interact with light having relatively long wavelengths.

Display panel having upconversion material and display device

The present application provides a display panel and a display device. The display panel includes a plurality of light-sensing circuits and a position detection circuit. The plurality of light-sensing circuits are disposed in the display panel and are arranged in an array. Each of the plurality of light-sensing circuits includes a light-sensing transistor. The present application disposes a quantum dot layer, which can absorb interactive light and convert its light intensity signal into an electrical signal, and determines an irradiation position of the interactive light through the position detection circuit, so that an interaction with light with a longer wavelength can be realized.

A method, an apparatus, and a system for accessing service by a Mobile Station (MS) are provided by the present disclosure. The method comprises the following steps: Gateway General Packet Radio Service (GPRS) Support Node (GGSN) or a next level gateway of the GGSN receives a service request carrying Virtual Access Point Name (VAPN) or a service request not including APN transmitted from a MS, performs a Deep Packet Inspection (DPI) processing to the service request, and identifies the type of the service; GGSN or the gateway sends the service request to the external data network corresponding to the service type. Therefore, accessing various types of mobile data services can be achieved through the service identification function of GGSN or GGSN gateway without modifying MS APN configuration by the mobile MS, therefore the service experiences for a MS user is enhanced effectively.
