Example Embodiment

[0045] figure 1 It is a schematic diagram showing the intuitive display system 100. The visual display system 100 includes a visual display 102 and glasses 104 for observing some modes. The glasses 104 include a left-eye filter 106 and a right-eye filter 108, respectively. The left-eye filter 106 and the right-eye filter 108 may include a stack of retarders to decode the first light beam and the second light beam emitted from the visual display 102.

[0046] The intuitive display 102 can work in several working modes, including: (1) advanced 2D mode, (2) enhanced color gamut mode using six primary color spectrum emitters, (3) privacy mode, (4) dual Image (or channel multiplexing) mode, and (5) stereo image mode. In the enhanced color gamut mode, glasses 104 are not required. In Mode 2 to Mode 4, the glasses 104 can be used to decode the image on the intuitive display 102. As will be known with reference to the following description, the filters 106, 108 may have different co...

Abstract

A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. Several modes of operation may be provided including an advanced 2D mode, and an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters. Another embodiment may be an optical structure for a multi-functional LCD display with wide color gamut and high stereo contrast. The optical structure may also be used to produce more saturated colors for a wider display color gamut and also may be used to produce a brighter backlight structure through light recycling of the wider bandwidth light back into the optical structure.

Description

[0001] Cross-references to related patent applications: This application is a non-provisional utility patent application claiming the commonly assigned title "Multi-primary backlight for multi-functional active-matrix liquid crystal displays" filed on January 4, 2013 Priority to US Patent Application No. 61 / 749,208, which is incorporated herein by reference in its entirety. technical field [0002] Embodiments disclosed herein relate generally to direct-view liquid crystal displays (LCDs), and more specifically, to processes, architectures, and techniques for enabling enhanced performance, new applications, and thus eyewear. Background technique [0003] Advances in the performance of active-matrix liquid crystal displays (AMLCDs), especially in televisions and gaming monitors, have been achieved through new backlight technologies and LCD display driver technologies. For example, LEDs with an improved RGB spectrum have shown better color gamut / efficiency than displays using...
