Abstract
The invention provides a process for producing a panel display screen. The process comprises a front screen project, wherein a front medium coating process in the front screen project comprises the following step of: adding a material layer with a volumetric expansion coefficient of more than 0.0015/DEG C on the surface of a front glass substrate for transferring stress generated in the process of machining the front glass substrate to the provided material. After the material is added on the surface of the front glass substrate, the stress borne by the front glass substrate is transferred and introduced into the material, the stress in the front glass substrate is effectively released, and the probability of screen crack is reduced; and moreover, after being added on the surface of the front glass substrate, the material always exists on the surface of the front glass substrate, namely the material always has an effect on the stress of the front glass substrate in subsequent processes, timely releases the stress of the front glass substrate, and reduces the phenomenon of crack of the panel display screen.
