Abstract
A phototherapeutic apparatus comprising a plurality of light sources and a control circuit, the plurality of light sources being arranged in a spatial pattern so as to form a display having a display area and each of the plurality of light sources being individually controllable to emit colored light; wherein the control circuit is configured to: receive image data; control the plurality of light sources to emit a spatially resolved pattern of emitted colored light, the spatially resolved pattern representing the received image data, wherein each of the plurality of light sources emits colored light perceivable by a human observer as having respective user-perceptible target image colors; wherein the control circuit is configured to control at least each of a first subset of the plurality of light sources to alternatingly emit respective first and second light, alternating at a color-flicker frequency; the first light having a first set of color components resulting in a first emitted color and the second light having a second set of color components resulting in a second emitted color; wherein the color-flicker frequency is selected high enough to cause the alternatingly emitted first and second light to be perceived by a human observer as light having a user-perceptible fused color corresponding to the corresponding target image color.
