Abstract: Light can be uniformly distributed in the bezel area by diffusing the light in the bezel area blocked by an upper case, or by providing an optical pattern for light concentration. Accordingly, the brightness of light is similar for all positions at the boundary between the bezel area and the display area, thereby solving the hot spot problem caused by a brightness difference depending on position.
Abstract translation: 光可以通过将光遮挡在由上壳体阻挡的边框区域中，或通过提供用于光集中的光学图案而均匀地分布在边框区域中。 因此，对于在边框区域和显示区域之间的边界处的所有位置，光的亮度相似，从而解决由根据位置的亮度差引起的热点问题。
