The demand for color head- and helmet-mounted displays (HMDs) is growing. Interest focuses on full-color systems, but a limited color repertoire is sufficient for some applications and can reduce cost and complexity significantly, especially when subtractive-color active-matrix liquid-crystal display (AMLCD) technology is used. We report a series of experiments that investigated important questions about the design and merits of two-primary color AMLCDs for HMD applications. Our main conclusion is that the image quality of a subtractive-color AMLCD with high (≥70%) aperture ratio is superior to a comparable, conventional color AMLCD. Evidence regarding requirements for resolution, aperture ratio, and gray scale is also provided.

ABSTRACTAs the active matrix flat panel market continues to grow, manufacturers are constantly looking for ways of gaining an advantage in the marketplace typically through increased performance, expanded functionality and/or reduced cost. The continuing trend of larger panel sizes and higher resolution poses interesting challenges for manufacturers in the areas of image quality and brightness. In particular, it has been clearly shown that as pixel dimensions shrink, relative crosstalk coupling coefficients increase while the area available for pixel electrodes and storage capacitors (Cδ,t) decreases, so that charge compensation drive schemes must be employed to eliminate visual artifacts. One approach to minimizing crosstalk and flicker is to increase Cδ,t, however this requires increased pixel area, usually at the expense of brightness due to smaller aperture ratio. Depending on design and process flow, it may be possible to replace the typical Cδ,t, insulator, SiNx:H, with a material of higher dielectric constant thereby vastly improving electrical performance without sacrificing brightness.
