20100039518 | PORTABLE INFORMATION PRODUCT WITH LASER PROJECTION - A portable information product with laser projection is disclosed. The portable information product can be a cellular phone, a portable computer, or a personal digital assistant, wherein the portable information product has a data processing device. The data processing device has a main circuit module for processing stored data and forming an image output signal according to the stored data. Additionally, a laser projection device is disposed in the data processing device and is electrically connected to the main circuit module. Specifically, the laser projection device has a laser LED module, an energy reduction module, and an image amplifying module. In which, the laser LED module generates a laser scanning projection according to the image output signal. After that, the laser scanning projection is transmitted to the energy reduction module for decreasing the energy level, and then the energy-reduced laser scanning projection is transmitted to the image amplifying module for enlarging the image size and projecting onto a display region. As a result, the data stored in the data processing device can be easily viewed by multiple users. | 02-18-2010 |
20160094818 | IMAGE DISPLAY APPARATUS - An image display apparatus includes: a light source unit that emits a light beam; a modulator that modulates an intensity of the light beam that is emitted from the light source unit; and an optical scanner that conducts spatial scanning with the light beam that is modulated by the modulator. The modulator includes a distribution unit that distributes a light beam that is incident to the modulator into a plurality of light beams, and a modulation unit that independently modulates the intensity of the light beams which are distributed in the distribution unit. | 03-31-2016 |

20110058045 | Scanning Mirror Position Determination - A scanning projector includes a mirror that scans in two dimensions, at least one of which is sinusoidal. A position sensor provides a position signal that represents an angular displacement of the mirror. The position signal is amplified by an amplifier with time variant characteristics. A beam position determination component compensates for the time variant characteristics of the amplifier. | 03-10-2011 |
20160147062 | SCANNING-TYPE PROJECTION DEVICE - A scanning-type projection device is provided with an emitted-light-intensity control unit for controlling the light intensity of a laser light emitted by a laser light source unit, a polarization direction control unit for controlling the polarization direction of the laser light, a scanning unit for scanning the laser light and generating a display image, and a divergence unit on which the laser light scanned by the scanning unit is incident. The emitted-light-intensity control unit has a polarization control element for controlling the polarization state of the laser light, and a polarizing plate on which the laser light emitted from the polarization control element is incident, and the polarization direction control unit adjusts the polarization direction of display light incident on a projection surface by controlling the polarization direction of the laser light emitted by the emitted-light-intensity control unit. | 05-26-2016 |
