Patent number: 8810502Abstract: A display system capable of switching 2D/3D mode includes a signal source, a 3D backlight control signal generation circuit, and a display. The signal source is used for transmitting a vertical synchronization signal and a left eye/right eye control signal. The 3D backlight control signal generation circuit is used for executing a first logic operation on the vertical synchronization signal and the left eye/right eye control signal to output a 3D left eye backlight control signal, and executing a second logic operation on the vertical synchronization signal and the left eye/right eye control signal to output a 3D right eye backlight control signal. The display displays 3D images according to the 3D left eye backlight control signal and the 3D right eye backlight control signal.Type: GrantFiled: February 23, 2011Date of Patent: August 19, 2014Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Tao-Ching Yu, Jhen-Shen Liao, Yung-Yu Hsieh

Publication number: 20130257827Abstract: A backlight module used in a display device is provided. The backlight module comprises a first and a second view-angle LED groups, a first and a second switches, a LED drive circuit for generating a drive current and a mode-control unit. The first and the second switches enable or disable the first and the second view-angle LED groups according to a first and a second PWM signals respectively. The mode-control unit operates the backlight module in 2D or 3D display mode according to a mode-control signal. In the 2D display mode, the first and the second switches enable the first and the second view-angle LED groups synchronously to emit light according to the drive current. In the 3D display mode, the first and the second switches enable the first and the second view-angle LED groups with an interlaced manner to emit light according to the drive current.Type: ApplicationFiled: August 9, 2012Publication date: October 3, 2013Applicant: CHUNGHWA PICTURE TUBES, LTD.Inventors: Yung-Yu HSIEH, Jhen-Shen LIAO, Hung-Hsiang CHEN
