Abstract: A flat panel display system includes a polymer memory provided thereon. The flat panel display may include a viewable portion and a non-viewable portion. In an embodiment, the polymer memory system may be provided on a non-viewable planar surface of the display. Owing to the large viewable area of many flat panel displays, it is expected that the polymer memory system can provide a large memory for a computer or other processor-based device without requiring any change in the device's form factor. Thus, such a system finds ready application in notebook computers, personal digital assistance and other mobile processor-based devices.

Abstract: A camera is provided that includes an array of optical detectors and an optical filter placed adjacent the array. The optical detectors output detection signals that are used to form control signals. The filter includes spatial sections of individually adjustable optical density. The optical densities are controlled by the individual control signals.

An objective lens and a housing form a stand alone unit. The detectors can have different responses to different wavelengths to achieve color specific effects. Methods are further provided for controlling the filter. The detection signals are scanned to ensure that a predefined filtering condition is met. If not, control signals are iteratively generated and applied to the filter until the condition has been met.

Abstract: In the typical LCD device, the ON/OFF inspection is performed by unit cell. However, in the case of the small size LCD device, since the liquid crystal cell substrate has many unit cells, the total inspection time is too long and the long handling time contributes to increasing the number of inferior cells. To solve these problems, the ON/OFF inspection of the liquid crystal cell for the small size LCD device having many unit cells is simultaneously performed for the entire liquid crystal cell substrate before cutting into the unit cells. Thus, the number of damaged cells during the inspection process and the process time can be reduced, and the yield can increase.

Abstract: The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams. The FPD structure has an image view plane which is continuous and remote from the pixel apertures or image source plane on the inside of the tiles.

Abstract: A composite liquid crystal panel includes a plurality of liquid crystal panels and a picture display surface. It cuts the border of each liquid crystal panel to a width of only one pixel, then bonding the panels together, installing the picture display surface on the liquid crystal panel, and distributing a portion of light from the normal pixels adjoining the border to the pixels corresponding to the border to resolve the gap problem. Light distribution is accomplished by using a pair of mirrors and a pair of reflecting surfaces to reflect the light of the pixels, so that light may be reflected above the pixels on the border and generate light. Then the pixels on the border and the pixels adjoining the border are redefined to form an image dot. Finally, through redistributing the light, the seams on the border may be completely eliminated.

Vertical seams (where tiles meet at the perimeter of the FPD) are sealed with a small amount of polymer. The seal may be constructed between a cover plate and a back plate, sandwiching the tiles. The AMLCD edges may be coated with either a non-permeable material or a polymer having an extremely low permeability (for example, Parylene™).

Then, the image for the right eye and that for the left eye may be seen independently and a stereoscopic image may be obtained.

Abstract: There is provided an improved method for laminating the components of a tiled display such as an AMLCD tiled display. In conventional laminating processes, forces are applied to the two parallel glass plates (i.e., the cover and back plates) separated by a liquid adhesive film. The two plates are squeezed together over their entire area forcing liquid laterally out from between the glass plates and tiles until the desired spacing or gap (filled with liquid adhesive) between the cover and back plates and the tiles is obtained. However, this process may require several hours to complete for large panels and, in addition the process is susceptible to trapping air bubbles in the adhesive. Consequently, the traditional process is not well suited for the mass production of large panels. The “pseudo” rolling-like lamination process of the present invention replaces the traditional lamination process and requires significantly less time.

Abstract: The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams.

Abstract: A seamless tiled display employs active liquid crystal display (LCD) and backlight. The active matrix elements of active LCD are mounted on the inside or outside of the front plate or back plate of LCD. A thin front plate and a thin sealing wall are used to reduce the seam width of the tiled LCD. A laser cutting is used for a thin LCD sealing. A spacer added adhesive array is deposited between pixels and between front plate and back plate to guarantee the uniformity of LC cells thickness. A laser riveting is still used for making a robust plastic LCD. A reflective layer is deposited on the side wall of back plate to reflect the light emitted from the backlight and to reduce the apparent seam width. In the backlight, there can be at least one set of red, green and blue light source operated at color sequential mode to display a color image without the use of color filters.
