LED illuminated projector

A method of generating a frame of an image using a projector, the method comprising:

• emitting light from an array of elements arranged in a plane, each element comprising at least three LEDs which have different respective colours;
• receiving the light emitted from the array of elements at an array of collector structures, each collector structure receiving light from a single LED at any one time to reduce an angle over which the single LED emits light;
• emitting the light from an array of collector structures that has been reduced in angle;
• and
• receiving the light from the array of collector structures at a projector unit and collimating the light such that a frame is formed;
• wherein the frame is full colour and formed from combining a plurality of subframes, each subframe being a single colour, the subframes formed through one or both of the following:
• a spatial movement of the array of elements with respect to the array of collector structures such that each collector structure receives light from a different LED during each subframe;
• or
• a displacement of the light emitted from each LED such that the light from each LED illuminates multiple pixels of the frame.

A display, comprising:

• a projector for generating a frame of an image, the projector comprising:
• an array of elements arranged in a plane, each element comprising at least three LEDs which have different respective colours;
• an array of collector structures, each collector structure configured to receive light from a single LED at any one time and reduce an angle over which the single LED emits light;
• and
• a projector unit configured to receive the light from the array of collector structures and collimate the light such that a frame is formed;
• wherein the frame is full colour and formed from combining a plurality of subframes, each subframe being a single colour, the subframes formed through one or both of:
• a spatial movement of the array of elements with respect to the array of collector structures such that each collector structure receives light from a different LED during each subframe;
• or
• a displacement of the light emitted from each LED such that the light from each LED illuminates multiple pixels of the frame.
