A backlight unit for a display device includes a light plate having a first light source and a second light source. The backlight unit also includes a light guide disposed proximate to the light plate to distribute light emitted from the first light source and the second light source. And a supplemental connector located at a connector position between the first light source and the second light source to engage the light guide to the light plate, where an optical characteristic of the light plate at the connector position or the supplemental connector is different from an optical characteristic at an adjacent position such that the supplemental connector is undetectable to an observer of the backlight unit. 一种用于显示设备的背光单元，包括具有第一光源和第二光源的光板。背光单元还包括光导，光导靠近光板设置，以分配从第一光源和第二光源发出的光。补充连接器，补充连接器位于第一光源和第二光源之间的连接器位置以将光导接合到光板，其中光板在连接器位置或补充连接器的光学特性与在相邻位置的光学特性不同，从而使得补充连接器对于背光单元的观察者而言是不可检测的。
