A display system includes a display and a light-transmitting member. The light-transmitting member has light-transmitting properties and is disposed to face a display screen of the display to dissipate heat generated by the display to outside of the display. The light-transmitting member has a higher thermal conductivity than quartz.

A scan display system includes a picture receiving unit, a scan needle, a picture display screen having first and second opposing surfaces, and a driving unit. The picture receiving unit is configured to receive picture data and transmits the picture data to the scan needle. The driving unit is configured to perform a picture scanning process by moving the scan needle to scan in a horizontal direction relative to the first of the picture display screen at a predetermined frequency. The scan needle is configured to emit light, representative of the picture data, to the first surface of the picture display screen to project image lines, each image line being formed by the scan needle during the scan. The picture display screen is configured to receive the emitted light on the first surface and display an image comprising the image lines on the second surface.

Display systems are described including augmented 1-dimensional pixel arrays and scanning mirrors. In one example, a pixel array includes first and second columns of pixels, relay optics configured to receive incident light and to output the incident light to a viewer, and a scanning mirror disposed to receive the light from the first and second columns of pixels and to reflect the received light toward the relay optics. The scanning mirror may move between a plurality of positions while the first and second columns emit light in temporally spaced pulses so as to form a perceived image at the relay optics having a higher resolution relative to the pixel pitch of the individual columns. Foveated rendering may provide for more efficient use of power and processing resources.

An image projector includes an illumination arrangement with a number of illumination sources and a tilt-mirror assembly, all operating under control of a controller. An optical arrangement directs illumination from the illumination sources towards the mirror and on to an image plane. A collimating arrangement collimates the illumination from the image plane to generate a collimated image directed to an exit stop. The controller (830) modulates an intensity of each of the illumination sources (808) synchronously with tilt motion of the mirror (814) according to the content of the digital image. In certain implementations, the illumination sources (808) are spaced apart. Although the tilt motion brings each illumination source to scans across only part of a dimension of the field of view, all of the illumination sources together scans across the entirety of the one dimension.

A holographic projection system is disclosed for cost-effectively generating “real image” holographic images. In at least one embodiment, the system provides an at least one primary image source configured for projecting a primary image via an at least one light ray. A computing device is in communication with the at least one primary image source and configured for providing the primary image to be subsequently projected by the at least one primary image source. A curved reflector is positioned and configured for receiving and reflecting the at least one light ray toward a focal point of the reflector, the at least one reflected light ray converging at an image point so as to create a hologram of the projected primary image at the image point, with said hologram being viewable by an at least one observer.

According to one embodiment, when displaying an image on a display panel, projecting an image which is displayed on the display panel, inclining the image which is projected from the display panel at a predetermined angle of bend, and reflecting the image which is projected from the display panel via a prism and guiding the image to a projection surface, a display device corrects input picture image of the prism based on characteristics contrary to the chromatic aberration characteristics of the prism.

A light emitting element 10 includes a first electrode 31, an organic layer 33 formed on the first electrode 31 and including a luminescent layer 33A composed of an organic luminescent material and a second electrode 32 formed on the organic layer 33, and further includes a light reflecting layer 50 provided below the first electrode 31. Light emitted in the luminescent layer 33A is resonated between the light reflecting layer 50 and an interface of the second electrode 32 and the organic layer 33, and a portion of the light is output from the second electrode 32.

The present invention provides a display device having a display panel. The display panel has a display surface and a plurality of pixels. At least some of the pixels include: an illumination unit and a display unit. The illumination unit has at least one illumination sub-pixel and at least one light orientation element respectively and correspondingly disposed on the at least one illumination sub-pixel, and illumination light from the illumination sub-pixel is directly or indirectly emitted from the display surface through the light orientation element. The display unit has at least one display sub-pixel, and display light from the display sub-pixel is directly or indirectly emitted from the display surface.

A direct retinal projector system that provides dynamic focusing for virtual reality (VR) and/or augmented reality (AR) is described. A direct retinal projector system scans images, pixel by pixel, directly onto the subject's retinas. This allows individual pixels to be optically affected dynamically as the images are scanned to the subject's retinas. Dynamic focusing components and techniques are described that may be used in a direct retinal projector system to dynamically and correctly focus each pixel in VR images as the images are being scanned to a subject's eyes. This allows objects, surfaces, etc. that are intended to appear at different distances in a scene to be projected to the subject's eyes at the correct depths.

A method for adapting a setpoint for a digital lighting unit, which is intended to be projected by a digital lighting unit of a motor vehicle, which includes a matrix light source and an optical system. The method includes a step of applying digital filtering to the digital setpoint. The filter used is capable of anticipating geometric aberrations induced by said optical system when projecting a digital setpoint.
