Abstract:
A cradle for connecting to a portable electronic apparatus is described. The cradle includes an AC adapter connector, a USB connector, a mini USB plug, and a USB signal detecting circuit. The USB connector is used to connect to a USB interface of a computer. The mini USB plug is used to connect to the portable electronic apparatus. The USB signal detecting circuit detects the USB_D+ and the USB_D− of the USB connector. When the computer is suspended from an operating state, the portable electronic apparatus is charged by the AC adapter through the mini USB plug. When the computer resumes normal operation, the USB connection between the portable electronic apparatus and the computer is automatically reestablished.
Abstract:
A light guide plate having micro-reflectors is applied to a back light module of a liquid crystal display. A light source is disposed on one side of the light guide plate. Each of the micro-reflectors is shaped like a pyramid protruding from the bottom of the light guide plate and comprises a transparent plane and two reflection planes. The transparent plane is disposed at right angle to the bottom of the light guide plate, facing and comparatively nearer to the light source. Both the reflection planes are inclined to the bottom of the light guide plate, facing the illuminating surface of the light guide plate and comparatively farther from the light source to reflect rays of light upward to increase luminance of the light guide plate, and thereby changing arrangement of the micro-reflectors to improve consistent luminance of the light guide plate.
Abstract:
A method for preventing uneven brightness in the stereoscopic display device is disclosed. The method for preventing the uneven brightness in the stereoscopic display device needs only one gamma voltage curve. By utilizing two white tracking look-up tables for respectively adjusting voltage division of left-eye images and right-eye images, the stereoscopic display device solves not only the problem of the 3D image sticking but also the problem of the uneven brightness in different frames.

An optical sheet adapted to relevant backlight module and LCD includes a light guiding side, a light emitting side, and a plurality of microstructures disposed on the light emitting side. Each of the microstructures is formed in an aspheric contour. At an intersection of an X-line and Y-line of each microstructure cross-sectionally defines a first bottom joint, which extending toward opposing sides of the X-line to define two symmetrical second bottom joints and upwardly extending from the Y-line to construct a top point. A first arc route is formed between the top point and the second bottom joint, and a second straight route is formed between the top point and the second bottom joint. A third route is defined round a cross-sectional outside contour of each microstructure, which is located within an area surrounded by the first and the second routes.
