Abstract: A liquid crystal display (LCD) that may include: a plurality of transistors groups forming a pixel array of said LCD, wherein the transistors groups are independently controllable; a plurality of backlight units, forming a backlight surface of said LCD, wherein the backlight units are independently controllable; a data refresh module configured to periodically refresh data at said groups of transistors, at a specified order, over a refresh cycle time; and a backlight control module configured to periodically dim the backlight units at said specified order over a backlight cycle time which is substantially shorter than the refresh cycle time.

Abstract: A HMD system including a visor mounted on a head of a user. The visor includes adjustable light transmission layer activated by activation radiation of at least a visible activation waveband and an Ultra Violet (UV) activation waveband. The visor defines a Line Of sight (LOS) projecting from a point on the visor and further defines a Field Of View (FOV) projecting from at least a section of the visor that surrounds the point on the visor. The visor is configured to admit an outside scene image. The HMD system further includes a luminosity sensor configured to detect luminosity within the FOV and a UV activation radiation source configured to selectively irradiate at least a portion of the visor with activation UV light included in the UV activation waveband according to luminosity detected by the luminosity sensor, thereby activating the adjustable light transmission layer.
