本实用新型的有益效果在于：在平板本体的正面和反面分别装设液晶屏总成和墨水屏总成，使平板两面分别具有不同的显示功能。不论是液晶屏总成或是墨水屏总成工作时均会发热，在墨水屏总成所在的反面上预留散热区域，不仅使得平板具有较大的散热区域，同时降低墨水屏的占屏率，缩小了平板的发热区域，从而确保平板的散热效果。其中，液晶屏总成可用于进行视频播放和直播授课等，而墨水屏总成适用于进行课堂测验、考试或者阅读等，由于墨水屏总成的显示内容受屏幕功能限制，因此当学生使用平板进行练习或阅读时，注意力能够集中于墨水屏总成上的内容。在本实用新型中，在平板本体的正反两面分别设置液晶屏总成和墨水屏总成，丰富了学生平板的功能，墨水屏的使用还能够减少对学生眼睛的伤害，散热效果好。
