Network communication connectivity tester for conference service

Abstract

The invention discloses a network communication connectivity tester for a conference service. The network communication connectivity tester comprises a reconnection key, a break key, a nano shell, a short circuit key, a switch, a menu, a liquid crystal display screen and a return key, wherein the menu is arranged on the liquid crystal display screen; the reconnection key and the switch are arranged at the upper part of the liquid crystal display screen; the short circuit key and the return key are arranged at the lower part of the liquid crystal display screen; the liquid crystal display screen comprises an upper glass substrate and a lower glass substrate; supporting bodies are arranged at the peripheral edges between the upper glass substrate and the lower glass substrate; a liquid crystal body is sealed between the upper glass substrate and the lower glass substrate; the inner sides of the upper glass substrate and the lower glass substrate are coated with silicon dioxide layers andpolyimide guide layers; the outer sides of the upper glass substrate and the lower glass substrate are respectively provided with an upper polaroid and a lower polaroid; the liquid crystal display screen further comprises multiple pixels; a layer of resin black film-substituted shading metal film is uniformly arranged on at least one glass substrate; and multiple light transmittance holes corresponding to the pixels are formed in the metal film.

Description

technical field [0001] The invention relates to the field of conference services, in particular to a network communication tester for conference services. Background technique [0002] At present, the network communication Unicom tester for conference service is a very commonly used tool in conference service.
