Patent number: 11536437Abstract: The backlight module includes multiple backlight units. Each backlight unit includes a first light emitting unit and multiple second light emitting units. The first light emitting unit has a first beam angle, and each second light emitting unit has a second beam angle which is narrower than the first beam angle. In a first mode, a light intensity of the first light emitting unit is equal to a first intensity, and a light intensity of the second light emitting units is equal to a second intensity. In a second mode, the light intensity of the first light emitting unit is equal to a third intensity, and the light intensity of the second light emitting units is equal to a fourth intensity. The first intensity is greater than the third intensity, and the second intensity is less than the fourth intensity.Type: GrantFiled: April 28, 2022Date of Patent: December 27, 2022Assignees: HannStar Display (Nanjing) Corporation, HannStar Display CorporationInventors: Chen-Hao Su, Chia-Feng Teng, Chin-Yung Liu

Patent number: 11506827Abstract: The backlight module includes the following units. Multiple first light emitting units are disposed on a top surface of a transparent substrate. A beam angle of the first light emitting units is greater than or equal to 30 degrees and less than or equal to 45 degrees. Multiple second light emitting units and a light guide plate are disposed on a bottom surface of the transparent substrate. Each second light emitting unit is disposed in a respective hole of the light guide plate. A light intensity of the first light emitting units in a first mode is smaller than that in a second mode. A light intensity of the second light emitting units in the first mode is greater than that in the second mode. In this way, the purpose of privacy protection can be achieved.Type: GrantFiled: May 25, 2022Date of Patent: November 22, 2022Assignee: HannStar Display CorporationInventors: Chen-Hao Su, Chia-Feng Teng, Chin-Yung Liu
