Embodiment Construction

[0024] A system 99 including an optical device 100 according to an embodiment of the present invention is shown in Figure 2A-3 . refer to Figure 2A -C, shows the optical device 100 having a first surface 106 and an opposing second surface 108 . In one embodiment, optical device 100 has a thickness of about 0.5 mm to about 5.0 mm. Typically first surface 106 is a planar optically smooth surface.

[0025] Such as Figure 2A -C, the optical device 100 includes a first transparent portion 102 having a first plurality of transparent protrusions 110 extending from a first surface 106 and a second transparent portion 103 having A second plurality of transparent protrusions 112 extend from the second surface 108 . Such as Figure 2A As shown in -C, the first plurality of transparent protrusions 110 self-aligns the second plurality of transparent protrusions 112 such that they are adjacently positioned and in contact with each other and form the plurality of openings 109 . In par...

Abstract

The present invention relates to an optical device for privacy or contrast enhancement of a viewing display. Also disclosed are a system including the optical device and methods of improving privacy or contrast of a viewing display, such as a plasma display panel, a liquid crystal display panel, an inorganic light emitting diode display panel, or an organic light emitting diode display panel.

Description

technical field [0001] The present invention relates to an optical device which can be used as a privacy screen or for contrast enhancement, in particular daytime / high ambient light contrast enhancement, of a viewing display such as a plasma A display panel, a liquid crystal display ("LCD") panel, an inorganic light emitting diode ("iLED") display panel or an organic light emitting diode ("OLED") display panel. Background technique [0002] Flat screens, especially plasma display panels (PDPs), are capable of producing color images with high definition, large screen diagonals, and have a compact structure. The plasma screen consists of a sealed gas-filled glass cell with electrodes arranged in a lattice. By applying a voltage, a gas discharge is induced, which primarily produces light in the vacuum ultraviolet range ("VUV"). Fluorescence converts this VUV light to visible light, and the front plate of the glass cell emits this visible light to the observer. [0003] When ...
