Abstract:
A display system including a first set of conductive electrodes, a second set of conductive electrodes, and a display medium. The first set of conductive electrodes is configured to receive a selection signal. The second set of conductive electrodes is configured to interact with the first set of conductive electrodes for activating the reading or writing of display data. The second set of conductive electrodes is configured to receive a data signal and to activate the reading or writing of a target area of the display device, in response to the selection signal to the first set of conductive electrodes and the data signal to the second set of conductive electrodes. The display medium is movably coupled with the first and second sets of conductive electrodes. One or both of the first and the second sets of conductive electrodes have at least two electrically independent regions having an independent signal input for each region.
Abstract:
A display unit comprises a display medium which is writable, erasable and displayable of an image and a rotatable writehead with a number of loop conductors parallel with each other. The display medium is capable of maintaining a written image without power. In operating of writing on the display medium, the loop conductors apply an electric field to a particular area of the display medium, changing the optical state of the particular area of the display medium. In operating of writing on the display medium, there is no relative motion between the display medium and the writehead.
Abstract:
A mask suitable for SLS laser crystallization includes a transparent substrate with a mask pattern thereon. The mask pattern includes a first region pattern and a second region pattern in mirror symmetry. When a laser beam irradiates on the mask to form a scanning region, the area of the scanning region is smaller than that of the mask pattern. The area of the mask pattern is larger than that of the scanning region of the laser beam. When the laser crystallization process is performed along a first direction, only a partial region on the mask is selected. When the laser crystallization process is performed along a second direction, the other region on the mask is then selected.
Abstract:
A method and a device for forming a poly-silicon film, using sequential lateral solidification (SLS) by laser irradiation through an optical device to pattern the laser beam so as to lengthen the crystalline grains and enhance the throughput. The optical device comprises a plurality of first transparent regions, a plurality of second transparent regions and a plurality of final transparent regions. The plurality of second transparent regions are disposed between the plurality of first transparent regions and the plurality of final transparent regions. The first transparent regions and the second transparent regions have a first width W1 and a first length L1, and the final transparent regions have a second width W2 and a second length L2. An mth first transparent region of the plurality of first transparent regions and an mth second transparent region of the plurality of second transparent regions are arranged in a tier-shape. An mth final transparent region of the plurality of final transparent regions is extended from the mth second transparent region of the plurality of second transparent regions.

A method for fabricating a thin film transistor (“TFT”) device includes providing a substrate, forming a patterned amorphous silicon layer over the substrate including a pair of first regions, a second region disposed between the pair of first regions, and at least one third region, each of which being disposed between and contiguous with the second region and each of the pair of first regions, the second region including a sub-region contiguous with each of the at least one third region, forming a heat retaining layer over the substrate, irradiating the patterned amorphous silicon layer with a laser through the heat retaining layer to form a patterned crystallized silicon layer corresponding to the patterned amorphous silicon layer including a grain boundary extending substantially across a crystallized sub-region corresponding to the sub-region, and forming a patterned conductive layer over a portion of a crystallized second region of the patterned crystallized silicon layer corresponding to the second region of the patterned amorphous silicon layer.

Abstract:
An amorphous silicon layer is formed on a substrate, and then a protective layer and a reflective layer are formed in turn to form a film stack on portions of the amorphous silicon layer. The reflective layer is a metal material with reflectivity of laser, and the protective layer is able to prevent metal diffusion. When an excimer laser heats the amorphous silicon layer to crystallize the amorphous silicon, nucleation sites are formed in the amorphous silicon layer under the film stack of the protective layer and the reflective layer. Next, laterally expanding crystallization occurs in the amorphous silicon layer to form poly-silicon having crystal grains with size of micrometers and high grain order.
