Patent number: 10429679Abstract: A display device includes a backlight module generating an emitting light having a first light distribution pattern, a switchable single-axis diffuser and a display panel. The first light distribution pattern has a light intensity exceeding a predetermined value within a first view angle range in a first direction. When the switchable single-axis diffuser is switched to a transparent mode, the emitting light passes through the switchable single-axis diffuser and maintains the first light distribution pattern. When the switchable single-axis diffuser is switched to a diffusion mode, the emitting light passes through the switchable single-axis diffuser and converts to a second light distribution pattern having the luminous intensity exceeding the predetermined value within a range of a second view angle in a first direction. The second view angle range is larger than the first view angle range.Type: GrantFiled: December 21, 2017Date of Patent: October 1, 2019Assignee: Coretronic CorporationInventors: Chong-Yang Fang, Wen-Chun Wang, Hsiung-Chun Hsu
