Interactive intelligent television blackboard

Abstract

The invention discloses an interactive intelligent television blackboard which comprises a liquid crystal display panel, two blackboards and a fixing frame. The middle of the fixing frame is fixedly connected with a horizontal rod. Engaging grooves are arranged on the top wall and the bottom wall of the liquid crystal display panel. A side of the bottom of the liquid crystal display panel is provided with a box body. An OPS computer host is placed in the inner cavity of the box body. By the OPS computer host and the liquid crystal display panel, courses on a computer can be displayed on the liquid crystal display panel. The liquid crystal display panel and the blackboards are on the same plane, so students can simultaneously watch the liquid crystal display panel and the blackboards such that the understanding abilities of the students are enhanced. The OPS computer host can shorten the time required by teaching courses, improves teaching efficiency, efficiently expands a learning range, and cultivates all-round talents. By a mortise handle lock, an authorized worker can open a box door just by a key to maintain or upgrade the OPS computer host, thereby ensuring the safety of public property.
