dc.description.abstractIn this dissertation, two LGPs for local dimming and autostereoscopic display are introduced. The brief intro-duction is below: i. Local Dimming (Chapter 3) Two-dimensional local dimming is a technique for reducing energy consumption and enhancing the contrast ratio of LCD. For this, locally luminance controllable BLU is required. Conventional local dimming BLU is made by back-lit type, which has comparably thick feature, or edge-lit type with limited local dimming per-formance. In this dissertation, an ultra-thin BLU for 2D local dimming was proposed and demonstrated by using newly designed LGP. The LGP shows the on-axis light extraction feature without prism sheets. Moreo-ver, due to its unique design of thin channel between each block, local isolation level is controllable. ii. Autostereoscopic Display (Chapter 4) An autostereoscopic display is a device for giving binocular disparity without any special glasses. Conven-tional ways to make autostereoscopic display are a temporal and spatial modulation. The proposed LGP can spatially modulate the scene of the display without any additional films like a barrier and a lenticular lens. So it reduces the thickness and cost of the display. The LGP also can be used in two-layered BLU for 2D/3D switchable display because the LGP is transparent. Moreover, I proposed a systematic feature for increasing viewing number and resolution by using spatial-/temporal- hybrid modulation.-
