Patent number: 8767094Abstract: A measurement method and a measurement device are disclosed. The measurement method is adapted to a 3D display capable of producing a plurality of viewing zones, which includes following steps. At least a part of a display area of the 3D display displays an image of one of the viewing zones. Light radiation amounts of a first position of the 3D display are detected with a light detector from different viewing angles. A viewing angle with a local maximum light radiation amount is taken as a reference viewing angle, a distance between the light detector and the 3D display along the reference viewing angle is changed, and light radiation amounts of a plurality of different second positions of the 3D display are detected in different distances. A distance at which light radiation amounts of the second positions are most uniform is taken as the optimal viewing distance.Type: GrantFiled: August 3, 2011Date of Patent: July 1, 2014Assignee: Industrial Technology Research InstituteInventors: Chou-Lin Wu, Kuo-Chung Huang, Kuen Lee

Publication number: 20120268451Abstract: A 3D display has a light grating unit inserted between a polarized light module and an image display unit. The light grating unit includes a tristate switching unit, a microretarder unit, and a polarizing film. By controlling the tristate switching unit of the light grating unit to be switched between three modes, a displayed image is switched between a 2D image at the third mode and a 3D image at the first and second mode. The first mode and the second mode are the switching effect to exchange image for the left eye and the right eye. When the light grating unit switches fast, e.g. in 2 times or more of the video rate, and the content updates synchronously, viewers will see 3D images in full resolution.Type: ApplicationFiled: October 19, 2011Publication date: October 25, 2012Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chao-Hsu Tsai, Kuen Lee, Chou-Lin Wu

Patent number: 8125582Abstract: A three-dimensional image display device including a polarized light module, a non-vertical polarized light barrier grating unit and an image display unit is provided. The polarized light module provides a polarized light. The non-vertical polarized light barrier grating unit is disposed in a light path of the polarized light to modulate the polarized light into a modulated polarized light in interlaced lines for output. The image display unit receives the modulated polarized light from the non-vertical polarized light barrier grating unit, and outputs two or more images with parallax.Type: GrantFiled: May 21, 2009Date of Patent: February 28, 2012Assignee: Industrial Technology Research InstituteInventors: Chou-Lin Wu, Wei-Liang Hsu, Chao-Hsu Tsai, Chang-Shuo Wu

Publication number: 20110096152Abstract: A stereoscopic image display including an image displaying unit and a directional light modulator is provided. The image displaying unit has a black matrix. The directional light modulator is disposed corresponding to the image displaying unit, wherein the directional light modulator comprises a plurality of constitutional groups repeating arranged in a first direction. Each of constitutional groups comprises a plurality of periodically changed structures, and each periodically changed structure in same constitutional group changes its size along the first direction.Type: ApplicationFiled: July 30, 2010Publication date: April 28, 2011Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Wei-Liang Hsu, Chi-Lin Wu, Chou-Lin Wu, Shin-Wen Yang

Publication number: 20080316597Abstract: A 3D display has a light grating unit inserted between a polarized light module and an image display unit. The light grating unit includes a dispersing liquid crystal unit, a microretarder unit, and a polarizing film. By controlling the dispersing liquid crystal unit of the light grating unit to be switched between a dispersing state and a transparent state, a displayed image is switched between a 2D image displaying mode and a 3D image displaying mode. The dispersing liquid crystal unit can be removed, so as to allow the image display unit to stay in the 3D image displaying mode.Type: ApplicationFiled: May 29, 2008Publication date: December 25, 2008Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chao-Hsu Tsai, Kuen Lee, Chou-Lin Wu

Publication number: 20070158477Abstract: A spraying device for atomizing a liquid is proposed. The spraying device includes a nozzle plate and an actuator. The nozzle plate is provided with a plurality of nozzle apertures. Each of the nozzle apertures includes an entry end for the liquid to enter and an exit end for the liquid to exit. The entry end and the exit end of at least one of the nozzle apertures are asymmetrical structures. The actuator is integrated with the nozzle plate to actuate atomization of the liquid. The spraying direction of a liquid droplet after the liquid is atomized can be controlled by modifying the shape of the exit end of the nozzle aperture.Type: ApplicationFiled: November 8, 2006Publication date: July 12, 2007Inventors: Chou-Lin Wu, Chi-Ming Huang, Chun-Fu Lu, Chun-Jung Chen

Patent number: 6926391Abstract: A micro fluidic module having at least a micro fluid channel barrier comprises at least an actuator, a firing chamber, a plurality of convergent fluid outlet channel and a plurality of convergent fluid inlet channel. The actuator (e.g. a heater) boils the working fluid and generates thermal bubble and instant high pressure to eject the working fluid outside and expel the working fluid through the fluid outlet channel. Then, the working fluid refills from the fluid inlet channel. Therefore, the working fluid flows consistently through the firing chamber. The working fluid flowing through adjacent firing chambers are arranged in different or consistent directions. Therefore, the refilling speed of the working fluid is increased, and the operating frequency of the module is improved.Type: GrantFiled: June 24, 2003Date of Patent: August 9, 2005Assignee: Industrial Technology Research InstituteInventors: Jinn-Cherng Yang, Ching-Yi Mao, Chou-Lin Wu
