Abstract:
A wafer-level electro-optical semiconductor fabrication mechanism and method for the same which improves upon traditional electro-optical semiconductor grain packaging methods. The present invention electrically connects semiconductor grains to the grains on a top surface of a wafer. this is done by either screen-printing or steel board-printing solder or silver paste onto the wafer. After that, the wafer is processed using the following steps: processing the devices, bonding with wire, packaging the wafer and finally cutting the wafer. Using this method raises the production yield while production times and costs are reduced. The wafer-level electro-optical semiconductor fabrication mechanism comprises: a wafer, an electro-optical semiconductor grain and conductive materials.

The present invention disposes contacts at one side or multiple predetermined sides of the substrate to improve airtightness and convenience for installation. In addition, the present invention also disposes an external frame or optical gratings to prevent external light interference. Thus, the package structure of the present invention is superior to conventional package structures, and is cheap.
Abstract:
A drive circuit of display and method for the same are described. Each drive circuit in an LCD panel is sequentially controlled by scanning signals so as to store temporarily a frame of image data in each storage capacitor. Then, a synchronization drive element in each drive circuit receives a synchronization control signal, so that a frame of each storage capacitor may be meanwhile sent to light-emitting units for achievement of the synchronization display on the LCD panel. Besides, a discharge transistor may be added and is controlled by a discharge signal before the synchronization drive element turns ON, which may effectively eliminate a pre-frame on the LCD panel.
Abstract:
A light emitting diode chip or chips array mounted on a substrate is surrounded by one or more side walls. The wall has an uneven reflecting surface to diverge the light emitted from the LED chip or chip array. The wall may have a triangular cross-section so that the emitted light diverges in all directions. When three double-sided reflecting walls surround three LED panels, the reflected light becomes omnidirectional hemispherically and can be used in a light bulb.
