The signature data of the device certificate is generated by signing the device parameter and the device public key by using an authentication private key of the certificate authentication server. The terminal then stores the device private key and the device certificate in the security zone.

Abstract: A manufacturing method of a liquid crystal display panel includes vertically irradiating a first substrate and a second substrate with ultraviolet light for alignment. An energy compensation device is formed and/or placed in an irradiation direction of the ultraviolet light. An angle difference of pretilt angles between liquid crystal molecules inside the first substrate and liquid crystal molecules inside the second substrate is greater than a preset angle. An energy intensity inside the first substrate or inside the second substrate is controlled by the energy compensation device, so that pretilt angle difference between the liquid crystal molecules inside the first substrate and the liquid crystal molecules inside the second substrate is large.
