Filed:

Aug 25, 2009

Appl. No.:

12/547351

Inventors:

Craig Lin - San Jose CA, US
Robert A. Sprague - Saratoga CA, US

Assignee:

SiPix Imaging, Inc. - Fremont CA

International Classification:

G02B 26/00

US Classification:

359296

Abstract:

The color display of the present invention involves a two particle system and is capable of displaying multiple colors with high quality black and white states. The color states are suitable for highlighting function. The color display does not require alignment between the electrodes and the display cells in which a display fluid is filled, which significantly reduces the complexity of the design and also lowers the manufacturing costs.

G02F 1/29

US Classification:

359296, 359245, 359316, 345 33, 345107, 349139

Abstract:

The present invention is directed to luminance enhancement structures for reflective display devices. The structure comprises columns and grooves, wherein each of said grooves has a cross-section comprising an apex angle and two edge lines. The structure increases the overall reflectance by reducing the total internal reflection, and as a result, the brightness of a display device is increased.

US Classification:

359290

Abstract:

The present invention is directed to luminance enhancement structure for reflective display devices. The luminance enhancement structure comprises grooves and columns, wherein said grooves have a triangular cross-section and a top angle, and said grooves and columns are in alternating order and in a continuous form in one direction. The luminance enhancement structure not only can reduce the total internal reflection, but also especially can enhance the on-axis brightness of a display device.
