摘要： A small projection type display unit capable of preventing the overlapping of the optical path of an incident light on that of an outgoing light in a reflection type light bulb and providing high-picture-quality projection images, and a rear projector and a multi-vision system using it. The projection type display unit comprises an illuminating optical system (2) for collecting light emitted from a light source (1) to form an illuminating light, a reflection type light bulb (6) for reflecting an illuminating light and outputting a modulation light that forms an optical image, a projection lens (7) for projecting an optical image formed by the reflection type light bulb, and a positive-power lens element (5). The lens element (5) is formed of one planoconvex lens and is disposed between the reflection type light bulb and the projection lens so that, with the convex surface directed toward the projection lens, an illuminating light passes through the lens element to illuminate the reflection type light bulb, and a modulation light output from the reflection type light bulb passes through the lens element to beam onto the projection lens.

摘要： A projection apparatus (18) forms an image frame (22) on a display surface (12), where the image frame (22) is a twodimensional array of pixels. The projection apparatus (18) has a laser (40) light source, an image modulator (42) for forming an image-bearing beam according to scanned line data, and projection optics (44) for projecting the image-bearing beam toward the display surface (12). A camera (20) obtains a sensed pixel array by sensing the twodimensional array of pixels from the display surface (12). A control logic processor (28) compares the sensed pixel array with corresponding image data to identify any portion of the image-bearing beam that is obstructed from the display surface (12) and to disable obstructed portions of the image-bearing beam for at least one subsequent image frame (22).

摘要： A display system (100, 200, 300, 350, 400, 450) for displaying an image is described. The display system (100, 200, 300, 350, 400, 450) typically comprises one or a plurality of individual light sources (102) and a light collecting stage (110, 210, 310, 410) which comprises a separate light collecting sub-system associated with each light source (102), or group of light sources (102). The display system (100, 200, 300, 350, 400, 450) typically comprises at least one light modulator (120) which is operable to modulate light received from the light collecting stage (110, 210, 310, 410) according to an image which is to be displayed. Finally a projection stage (130) is provided for projecting the image, typically on a projection screen. The present invention also relates to a corresponding method. The present invention is especially useful with light sources having a packaging around the light emitting surface such that the light sources cannot be physically placed adjacent to each other.

摘要： An illuminator comprising two light source sections (101, 102), a rod integrator (1), and a relay lens system (4) for introducing a light flux emitted from the rod integrator (1), wherein the rod integrator (1) is a columnar optical element having an incident end face (130F) as the upper bottom and an exit end face (130B) as the lower bottom. One opposite side faces out of four side faces form such a part that the planes face each other in parallel while the other opposite side faces form a taper face where the planes face each other while inclining at a specified angle such that the opposite side faces recede from the incident end face (130F) toward the exit end face (130B). Lights from the two light source sections (101, 102) are converged to the vicinity of the incident end face (130F) of the rod integrator (1).

摘要： The invention relates to an assembly for projecting an image onto a projection surface. Said assembly comprises a light source (1), which emits light and can be used to create a luminous field (3), a reflective light modulator (12; 13; 14), which can be exposed to light that exits the luminous field (3) and which modulates said light to create an image and a projection optical system (16) connected downstream of the light modulator (12; 13; 14), which can be impinged by the modulated light, to project the image onto the projection surface (17). The invention is characterised in that an optical device (7; 23; 31; 33; 34) is connected upstream of the light modulator (12; 13; 14), said device both focussing the light emanating from the luminous field (3) onto the light modulator ( 12; 13; 14) and also focussing the light modulated by the light modulator (12; 13; 14) onto an intermediate plane (ZE) located upstream of the projection optical system (16), in order to create on said plane (ZE) an intermediate image that can be projected by the projection optical system onto the projection surface.
