JASPER DISPLAY CORP.

JASPER DISPLAY CORP. Patent applications
Patent application number	Title	Published
20120086733	PIXEL CIRCUIT AND DISPLAY SYSTEM COMPRISING SAME - A display system which includes a display controller, a display unit, and a light source is disclosed. The display controller includes a processor unit, a memory device, a voltage source and, optionally, a light source control unit. The display unit includes an array of pixel cells and circuitry to receive logic and control voltages and data and operate the display, a transparent counter electrode, and a liquid crystal layer disposed between the two alignment layers. The pixel cell includes a storage element, a DC balance control switch, a pixel voltage override circuit, an inverter able to select between two voltages available to it, and a pixel electrode/mirror. In different modes of operation the pixel mirror voltage may be determined by the storage element or by the pixel voltage override circuit. The display system may display images in one period and reset to a fixed state in another period.	04-12-2012
20110273633	PROJECTION SYSTEM AND METHOD FOR ALTERNATELY OUTPUTTING DIFFERENT POLARIZED IMAGE LIGHT SOURCES - A projection system for alternately outputting different polarized image light sources includes a polarizing beam splitting module, an image display module and a light polarization switch module. The polarizing beam splitting module has at least one polarizing beam splitting element for intermittently receiving a plurality of input light sources according to different time sequences. The image display module has at least one reflective image display panel disposed beside a first side of the polarizing beam splitting element. The light polarization switch module has at least one transmission LCD light valve disposed beside a second side of the polarizing beam splitting element. Therefore, the image light sources with P polarization and the image light sources with S polarization can be intermittently and alternatively projected from the projection lens onto the surface of the object by switching the transmission LCD light valve to ON/OFF state according to different time sequences.	11-10-2011
20110249238	PROJECTION SYSTEM FOR SIMULTANEOUSLY OUTPUTTING IMAGE LIGHT SOURCE WITH DIFFERENT POLARIZATIONS AND METHOD OF USING THE SAME - A projection system for simultaneously outputting image light source with different polarizations includes a polarizing beam splitting module, an image display module and an image projecting module. The polarizing beam splitting module has a first polarizing beam splitting element for receiving light source, a second polarizing beam splitting element, a third polarizing beam splitting element and a fourth polarizing beam splitting element. The image display module has a first reflective image display panel disposed beside the second polarizing beam splitting element and a second reflective image display panel disposed beside the third polarizing beam splitting element. The image projecting module has at least one projection lens disposed beside the fourth polarizing beam splitting element.	10-13-2011
