Abstract

The invention relates to novel liquid crystal display equipment with a self-protection function. The novel liquid crystal display equipment comprises a liquid crystal display screen and a dust preventing mechanism. The dust preventing mechanism comprises two dust preventing components. Each dust preventing component comprises a rotary shaft, dust preventing cloth and an extension spring, wherein the extension spring is located in the rotary shaft, one end of the dust preventing cloth is fixed in the rotary shaft through the extension spring, and the dust preventing cloth winds the outer periphery of the rotary shaft. The novel liquid crystal display equipment has the advantages that the two dust preventing cloth is tensioned by the extension springs, and dust preventing of the liquid crystal display screen is guaranteed; a fixing block is fixed in position by the aid of a limit component, fixing reliability is guaranteed, and equipment reliability is further increased; in addition, the type of each of a first operational amplifier, a second operational amplifier and a third operational amplifier in a temperature detecting circuit is LMV324, low temperature drift coefficient is achieved, and accordingly circuit signal detection reliability is increased, and equipment reliability is increased.
