摘　　要：本文介绍了液晶玻璃中的残余应力会在面板厂加工、裁切时造成玻璃板形变,导致画质不良,玻璃生产厂需有效管控玻璃的应力。玻璃的应力从作用方向上分为张、压应力,故准确测量张、压应力将有效指导应力对策。国际上液晶玻璃基板生产厂家大都采用测量分析玻璃板张、拉应力的方法来对策玻璃板应力。This paper introduces that the residual stress in the liquid liquid crystal glass substrate will cause the deformation of the glass plate during the processing and cutting of the panel factory,resulting in poor picture quality.Therefore,glass manufacturers need to effectively control the stress of the glass.The stress of glass is divided into tensile and compressive stress from the direction of action,so accurate measurement of tensile and compressive stress will effectively guide the stress countermeasures.International LCD glass substrate manufacturers(such as Corning)use the method of measuring and analyzing the tension and tensile stress of the glass plate to counter the stress of the glass plate.
