Abstract: A first network device may receive, from an application server, a first request for a dedicated bearer session for an application with a quality of service (QoS) and for a notification of an idle session for the application. The first network device may generate, based on the first request, a second request to be notified regarding expiration of an idle session timer for the application, and may provide the second request to a second network device. The first network device may receive, from the second network device and based on the second request, a notification of expiration of the idle session timer for the application, and may provide, to the application server, the notification of expiration of the idle session timer for the application.

Abstract: The present disclosure provides a light valve, a display device and a display method. The light valve includes: at least one fixation member fixed onto a substrate; and at least one movable member capable of moving relative to the fixation member to switch the light valve between a first state where the light valve is provided with a slit through which a light beam passes and a second state where the light valve prevents the light beam from passing therethrough.

Abstract: The present disclosure provides a pixel unit including a plurality of sub-pixels of different colors. Each sub-pixel includes a first transflective layer, a wavelength selective cavity, and a second transflective layer disposed successively along an incident light direction. A height of the wavelength selective cavity of each sub-pixel in the incident light direction is designed so as to select light having a wavelength corresponding to a color of the sub-pixel from light which is incident through the first transflective layer and reflected between the first transflective layer and the second transflective layer, and selected light exits through the second transflective layer. The present disclosure further provides a display substrate and a display panel.

Abstract: A display panel includes an array substrate, and a plurality of display units disposed on the array substrate each of which includes a display sub-pixel for receiving sunlight radiation and performing display, a solar cell disposed adjacent to the display sub-pixel and configured to receive sunlight radiation and perform photoelectric transformation, a micro-electromechanical optical valve disposed above and movable over the display sub-pixel and the solar cell to control a light transmittance of the display sub-pixel, and a blocking structure disposed at an edge of the display unit to limit the movement of the micro-electromechanical optical valve within the display unit.
