A viewing device comprising a controller, a transparent display and a visual shutter. The controller is configured to determine a color of virtual content to be displayed; determine a background color contrasting the virtual content displayed; determine a display area corresponding to where the virtual content is to be displayed; cause the visual shutter to enable a background to the virtual content to be displayed, the background having the contrasting background color thereby providing a contrasting background to the displayed virtual content (DVC); and to cause the transparent display to display virtual content for overlapping at least one visual object (VO) perceivable through the transparent display at least partially onto the background. The visual shutter is configured to enable the background by operating in a mode wherein at least a portion of the visual shutter is blocked to obstruct the VO in the blocked portion of the visual shutter.

An electrophoretic medium comprises a fluid and first (B), second (Y), third (R) and fourth (W) particles dispersed in the fluid and having differing colors. The first (B) and third (R) particles bear charges of one polarity and the second (Y) and fourth (W) particles bear charges of the opposite polarity, The first particles (B) have a greater zeta potential than the third particles (R), and the second particles (Y) have a greater zeta potential than the fourth particles (W). One of the particles (W) is white, one of the non-white particles (B) is partially light-transmissive, and the remaining two non-white particles are light-reflective. To display the color of a mixture of the first (B) and second (Y) particles at a viewing surface, the medium is driven to display the second particles (Y) at the viewing surface, then a first driving voltage is applied for a first period to drive the second (Y) and fourth (W) particles towards the viewing surface, then a second driving voltage, of opposite polarity to and lower magnitude than, the first voltage, is applied for a second period less than the first period, and finally the applications of the two driving voltages are repeated.

A control method is provided for suppressing a flicker phenomenon even if frame periods vary in length. The control method controls an emission period and an extinction period of a frame period, which is a period in which one image continues to be displayed. When a signal indicating start of a frame period is detected, as the frame period, n subframe periods that configure the frame period, where n is an integer greater than or equal to 2, are sequentially started from the first subframe period, after a predetermined period of time has elapsed since the detection of the signal. All of the n subframe periods are controlled to have a substantially same length determined in advance and to have a substantially same ratio between the emission period and the extinction period, determined in advance, the ratio being referred to as a duty ratio.
