一种是“侧光式”，灯管安排在电视机的侧面；另一种是“全阵列式”，灯管以网格状排列于屏幕的后方。

One is called "edge-lit", with lights set around the television frame; the other is "full-array," with lights set behind the screen in a grid pattern.

因为这样能使用较少的灯管，侧光式比全阵列式更便宜。

Since they have fewer lights inside, edge-lit LED models are cheaper compared to full-array models.
