20100149742 | HANDHELD ELECTRONIC DEVICE AND OPERATING METHOD THEREOF - A handheld electronic device and an operating method thereof are provided. The handheld electronic device includes a first body, a second body, and a moving assembly. The moving assembly includes a sliding module and at least one rotating module. The sliding module is coupled to the second body, wherein the second body is moveable between a first position and a second position. The rotating module is coupled between the first body and the sliding module so that the second body is rotated relative to the first body. The second body is automatically rotated from the second position to a third position to form a first angle with the first body. The second body can be rotated between the third position and a fourth position to form a second angle with the first body, wherein the second angle is greater than the first angle. | 06-17-2010 |
20110096001 | OPTICAL TOUCH CONTROL SYSTEMS - An optical touch control system. A monitor includes a first side, a second side, a third side, and a fourth side sequentially connected to each other. A first light guide, a second light guide, and a third light guide are respectively disposed on the first, second, and third sides of the monitor. A first beam splitter is adjacent to the first and second light guides. A second beam splitter is adjacent to the second and third light guides. A first light source and a second light source are respectively adjacent to the first and second beam splitters. A first image sensor is disposed between the first and fourth sides of the monitor. A second image sensor is disposed between the third and fourth sides. The first and second image sensors receive light transmitted onto the monitor via the first, second, and third light guides, identifying touch control operations. | 04-28-2011 |
20110102375 | OPTICAL TOUCH MODULE - An optical touch module includes a display panel, an optical sensor and a light emitting unit. The optical sensor is disposed on a corner of the display panel. The light emitting unit is disposed on the optical sensor and includes a light emitting member and a compensating member. The light emitting member emits light with a first light strength along a first direction and light with a second light strength along a second direction, wherein the first light strength is greater than the second light strength. The compensating member is disposed on a side of the light emitting member. After the lights pass through the compensating member, the second light strength is increased. | 05-05-2011 |

20120105374 | Touch device and touch method - A touch device to sense and compute the coordinate of a touch object is provided. The touch device comprises a panel, a light-emitting element, an image sensor, a reflective strip and a processing unit. The panel has a sensing area surrounded by first to fourth boundaries where the first and the third boundaries define an x direction and the other two boundaries defines y direction. The light-emitting element and the image sensor are located on the first boundary with a specific distance therebetween. The reflective strip is located on the second to fourth boundaries. When the touch object touches the sensing area, a first and a second light path from the light-emitting element to the image sensor are blocked to form a real and a virtual image such that the processing unit computes the coordinate of the touch object according to the real and the virtual images. A touch method is disclosed herein as well. | 05-03-2012 |
20120223915 | TOUCH MODULE AND TOUCH DISPLAY USING THE SAME - A touch module disposed on a display panel of a touch display is provided. The touch module includes a glass substrate, a polymer layer, a lateral-side light sensor and a vertical-side light sensor. The polymer layer is transparent and flexible. The lateral-side and the vertical-side light sensors are sandwiched between the glass substrate and the polymer layer, and disposed on a lateral edge and a vertical edge of the substrate. A transparent transmission layer is formed between the glass substrate and the polymer layer. When a touch event is triggered on the polymer layer, the backlight corresponding to the touch point is transformed into a side-oriented backlight, which is transmitted in the transparent transmission layer and captured by the lateral-side and the vertical-side light sensor. | 09-06-2012 |
20140284096 | CASING OF ELECTRONIC DEVICE AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing a casing of an electronic device including the following steps is provided. A metallic housing is provided, wherein the metallic housing has an inner surface and an outer surface opposite to the inner surface. A plurality of apertures are formed on the inner surface of the metallic housing. A non-conductive layer is formed on the inner surface of the metallic housing, and part of the non-conductive layer is extended into the apertures. The outer surface of the metallic housing is dyed to form the casing of the electronic device. A casing of an electronic device is also provided. | 09-25-2014 |
20150205442 | OPTICAL TOUCH SCREEN - The present invention provides an optical touch screen including a transparent panel, a camera module and at least one retro-reflector. The transparent panel includes a bottom surface and a touch surface opposite to each other, a corner and sides. The camera module disposed on the corner includes a light source, a light guide component, an optical clear adhesive and an optical sensor. The light source is used for emitting an incident light, in which a vertical distance between the light source and the touch surface is greater than a vertical distance between the bottom surface and the touch surface. The optical clear adhesive is used to fix the light guide component on the transparent panel, and the incident light enters the transparent panel through the light guide component and the optical clear adhesive with total reflection between the bottom surface and the touch surface. | 07-23-2015 |
