Patent number: 8767055Abstract: An image display method of a stereo display apparatus is provided. The image display method includes the following steps. A stereo display apparatus is provided, wherein the stereo display apparatus provides N view zones for a viewer and includes a periodic structure and a pixel plane. N view zones are divided in a space according to the N value. Projection areas corresponding to each of the view zones are formed on the pixel plane by the periodic structure, wherein each of the projection areas corresponds to at least one sub-pixel unit on the pixel plane. Image information of each view zone is obtained according to the corresponding sub-pixel units. A stereo image is displayed by blending image information of each view zone.Type: GrantFiled: September 25, 2011Date of Patent: July 1, 2014Assignee: Au Optronics CorporationInventors: Yu-Chieh Chen, Chao-Yuan Chen, Ching-Ming Wei

Patent number: 8203521Abstract: A method of generating frame control signals for reducing reaction time comprises following steps: analyzing an input frame signal; generating a first reference liquid crystal control signal of a frame; setting a second liquid crystal control signal range and thereby generating a second reference liquid crystal control signal; generating a second backlight control signal according to the first reference liquid crystal control signal and the second reference liquid crystal control signal; and generating a second liquid crystal control signal of each pixel according to the second backlight control signal. By confining the second backlight control signal to the second liquid crystal control signal range, the reaction time of the liquid crystals is reduced and the frame quality of LCD devices is enhanced.Type: GrantFiled: January 9, 2008Date of Patent: June 19, 2012Assignee: National Chiao Tung UniversityInventors: Fang-Cheng Lin, Yi-Pai Huang, Ching-Ming Wei, Han-Ping D.

Patent number: 8184087Abstract: The present invention provides a display method for an LCD device with reduced color break-up, comprising the following steps: generating a control signal for each sub-frame, and displaying the sub-frames successively. The present invention generates, according to brightness of a screen to be displayed, second backlight control signals and second LC control signals for each display region in the each sub-frame and then, according to the second backlight control signals and the second LC control signals, displays a chromatic sub-frame and a plurality of monochromatic sub-frames successively so that the screen to be displayed can be viewed through human vision. The present invention can not only facilitate reducing color break-up (CBU) of the LCD device, but also can contributes to the LCD device advantaged by high contrast, high color saturation, low power consumption and low manufacturing costs.Type: GrantFiled: January 4, 2008Date of Patent: May 22, 2012Assignee: National Chiao Tung UniversityInventors: Fang-Cheng Lin, Yi-Pai Huang, Ching-Ming Wei, Han-Ping D.

Publication number: 20120113511Abstract: A display device for generating three-dimensional images includes a display panel, a reinforcing plate, and a light-splitting layer. The reinforcing plate is attached to at least one surface of the display panel to improve the resistance to the flexing and deformation of the display panel. If the reinforcing plate is attached to a display surface of the display panel, the reinforcing plate needs to be light transmissible. The rigidity of the reinforcing plate should be greater than the rigidity of the display panel so that the attached reinforcing plate is able to support and prevent flexing of the display panel. The light-splitting layer is disposed corresponding to the display surface and distant from the display panel by a gap. An air layer is formed between the light-splitting layer and the display surface.Type: ApplicationFiled: October 28, 2011Publication date: May 10, 2012Applicant: AU OPTRONICS CORPORATIONInventors: Yi-Chih Chen, Ching-Ming Wei

Publication number: 20100245396Abstract: A display apparatus and driving method thereof are provided. The driving method is adapted for driving a backlight module and a display panel thereon, and includes at least the following steps. Firstly, a backlight data and a display data are outputted according to a color distribution of an expected image. Afterwards, a light-emitting pattern whose color distribution corresponds to the color distribution of the expected image of the backlight module is determined according to the backlight data. Besides, a display pattern of the display panel is determined according to the display data. The expected image is displayed through the light-emitting pattern and the display pattern.Type: ApplicationFiled: May 18, 2009Publication date: September 30, 2010Applicant: CHUNGHWA PICTURE TUBES, LTD.Inventors: Yi-Pai Huang, Han-Ping D.

Publication number: 20100045707Abstract: A color sequential method for displaying images is suitable for applying in a display with pixels. Each of frames is formed by displaying a first sub-frame, a second sub-frame and a third sub-frame within a displaying time by the pixels. By calculating differences in gray levels between neighboring pixels, variations are gained. Then, a first just noticeable difference is provided, and the pixels having the variations larger than the first just noticeable difference are detected. Next, times of displaying the first, the second and the third sub-frames in the pixels are raised within the displaying time.Type: ApplicationFiled: October 31, 2008Publication date: February 25, 2010Applicant: CHUNGHWA PICTURE TUBES, LTD.Inventors: Yi-Pai Huang, Fang-Cheng Lin, Ching-Ming Wei, Wuan-Zheng Yi, Sheng-Chang Chen, Chi-Neng Mo, Han-Ping D.
