20130038530 | OPTICAL POINTING APPARATUS AND PORTABLE ELECTRONIC DEVICE COMPRISING SAME - Disclosed is s pointing device having enhanced visibility and aesthetics by providing a surface thereof with a light emitting zone for implementing decorative illumination, and a portable electronic apparatus including the pointing device. The pointing device includes a detector for detecting movement of an object; a housing including a housing body covering the detector and a light emitting zone provided in the housing body to allow visible light to be transmitted therethrough; a light source emitting illumination light containing visible light to illuminate the light emitting zone; and a light guide for changing a light path of the illumination light emitted from the light source so that the illumination light exits from the light emitting zone to an outside of the housing. | 02-14-2013 |
20120162075 | ULTRA THIN OPTICAL POINTING DEVICE AND PERSONAL PORTABLE DEVICE HAVING THE SAME - An optical pointing device including a Printed Circuit Board (PCB); an infrared Light Emitting Diode (LED) provided on a side of the PCB; a cover plate for detecting motion of a subject, which is placed in an upper portion of the optical pointing device; an image forming system lens placed below the cover plate and configured to condense a light reflected from the subject; an optical image sensor for receiving a reflected image of the subject and detecting motion of the subject; and an optical coating unit placed on the optical image sensor. The cover plate and the optical coating unit are made of a material capable of passing a wavelength of infrared rays which cannot be perceived by a user's eye. A first cut off wavelength of the cover plate is shorter than a second cut off wavelength of the optical coating unit. | 06-28-2012 |
20110018800 | OPTICAL POINTING APPARATUS AND PORTABLE ELECTRONIC APPARATUS WITH THE SAME - An optical pointing device and a portable electronic device having the same, in which external noise light and/or noise light due to diffused reflection or the like is prevented from being introduced into an optical sensor enhancing precision of operation and providing a housing with improved structure. The device includes an infrared source; a cover having a cover plate transmitting infrared rays from the IR source for reaching a subject out of the cover plate and a cover frame that supports the cover plate; an optical unit in the cover and on which the infrared ray reflected from the subject is incident; and an optical sensor sensing the infrared ray incident thereon from the optical unit; the cover plate has a base coupled to the cover frame, and an IR band-pass filter layer provided on one side of the base. | 01-27-2011 |
20100194712 | OPTICAL POINTING DEVICE AND PORTABLE ELECTRONIC DEVICE HAVING THE SAME - Disclosed herein is an optical pointing device as a user interface for electronic devices such as communication terminals and the like. The optical pointing device includes a light receiving part, an optical unit transferring light to the light receiving part and including a reflection part disposed in an optical path, a frame body integrally formed with the reflection part to support the reflection part, a cover covering the frame body and having an interface surface, and a light source illuminating the cover. The optical pointing device reduces the number of components and permits convenient and easy assembly, thereby significantly improving productivity while reducing assembly defect. | 08-05-2010 |
20090184852 | Optical joystick and portable electronic device having the same - An optical joystick and portable electronic device having the same are disclosed, by which malfunctions of the optical joystick due to sunlight or external illumination light are prevented or minimized. Therefore, precision of the optical joystick can be enhanced. The optical joystick according to the present invention includes an infrared light source, a cover part having a contacting surface for a contact by a subject, a light-receiving part detecting the infrared ray, and an optical member provided on an light path of the infrared ray traveling from the cover part toward the light-receiving part, wherein the cover part comprises a cover base and an infrared ray pass layer blocking out external noisy light on a predetermined band and passing substantially a wavelength band of infrared rays. | 07-23-2009 |
