# 锁屏

教师可以锁定班级中一名或多名学生的屏幕。可以配置要在锁定屏幕时显示的消息和背景图像（若使用）。请参阅[锁屏](/faronics-insight-docs/chinese/shi-yong-faronics-insight/insight-teacher-kong-zhi-tai/she-zhi/suo-ping.md)，获取更多信息。

教师启用"专注"限制以锁定屏幕时，为班级配置并选择的锁屏设置将应用于学生计算机。如果没有为当前班级创建或选择设置，则将应用默认设置。

例如，教师已设置锁屏设置，以显示"请专心听课"的消息，并配有背景图片。当教师选择锁定学生的屏幕时，学生计算机将在其屏幕上显示预设消息和指定的背景。
