20080251019 | SYSTEM AND METHOD FOR TRANSFERRING A SUBSTRATE INTO AND OUT OF A REDUCED VOLUME CHAMBER ACCOMMODATING MULTIPLE SUBSTRATES - The present invention comprises a system and method for transferring a substrate into and out of a chamber configured to accommodate multiple substrates. In one embodiment, the system comprises a chamber housing that includes a first substrate support tray and a second substrate support tray independently movable along a vertical axis, and a substrate conveyor movable into and out of the chamber housing. The first substrate support tray and the second substrate support tray are movable to a position where a portion of the second substrate support tray is received in the first substrate support tray. | 10-16-2008 |
20080284760 | LOCALIZATION OF DRIVER FAILURES WITHIN LIQUID CRYSTAL DISPLAYS - Methods and apparatus for determining whether a malfunctioning pixel in a large area substrate, such as a liquid crystal display (LCD) panel, is due to the pixel itself or to the driver circuit for that pixel and for localizing any driver circuit defects are provided. In an effort to localize the driver circuit defects, test pads coupled to the input and/or output of certain driver circuits may be fabricated on the substrate. The voltage or charge of these test pads may be detected using any suitable sensing device, such as an electron beam, an electro-optical sensor, or an electrode in close proximity to the surface of the pixels and/or drivers capacitively coupled to the pixel or driver. For some embodiments, the defective driver circuits may be repaired in the same area as the test area or may be transported via conveyor or robot to a separate repair station. | 11-20-2008 |
20090122056 | DRIVE APPARATUS WITH IMPROVED TESTING PROPERTIES - Embodiments of the present invention relate to a drive electronics for driving a display with a matrix | 05-14-2009 |
20090179656 | LIGHT-ASSISTED TESTING OF AN OPTOELECTRONIC MODULE - The present invention relates to a device for testing an optoelectronic module, comprising a first source for generating an electromagnetic beam or particle beam, a second source for illuminating the optoelectronic module; and a detector. In addition, a method for testing an optoelectronic module is provided comprising illuminating the optoelectronic module, directing an electromagnetic beam or particle beam and detecting defects in the optoelectronic module. The illumination additional to the electromagnetic beam or particle beam makes defects visible which otherwise would not be detected. | 07-16-2009 |
20090195262 | IN-LINE ELECTRON BEAM TEST SYSTEM - A method and apparatus for testing a plurality of electronic devices formed on a large area substrate is described. In one embodiment, the apparatus performs a test on the substrate in one linear axis in at least one chamber that is slightly wider than a dimension of the substrate to be tested. Clean room space and process time is minimized due to the smaller dimensions and volume of the system. | 08-06-2009 |
