    Abstract: An optical scanner and an optical scanning control method. The optical scanner includes a light source configured to emit light, a light deflector configured to deflect the light emitted from the light source to scan a scanning area two-dimensionally in a main scanning direction and a sub-scanning direction, and a photodetector configured to detect scanning light deflected by the light deflector to perform scanning on a detection field included in the scanning area. In the scanning area, a detection scanning area is formed by the scanning light so as to include an end of the detection field, and a size of the detection scanning area is changed. The optical scanning control method includes forming a detection scanning area by scanning light so as to include an end of a detection field included in a scanning area that is two-dimensionally scanned, and changing a size of the detection scanning area.

    Abstract: The image display apparatus generates a driving control signal for generating image light on the basis of an image signal, and allows an image projector to generate the image light to form a pixel on a screen in accordance with a modulation timing by performing modulation driving for a light source, and to generate the image light so as to scan the screen while a light emission direction of the image light changes by performing scan driving, allows a gaze-direction detector to detect a gaze direction of a user, and allows a projection-direction driver to change a projection direction of the image light in accordance with the gaze direction. In the first mode, the image display apparatus controls modulation driving and scan driving so that a configuration of a pixel region on the screen changes from a relatively high pixel density region to a relatively low pixel density region.

    Abstract: An optical system comprises a linear illumination source configured to emit light, a first scanning stage configured to receive the light and to scan the light, and a second scanning stage. The linear illumination source is configured to generate light forming a vertical field of view based on the one or more output signals received from a controller modulating the one or more output signals comprising image data defining content. The first scanning stage redirects portions of the light to generate an output defining a horizontal field of view based on the one or more output signals of the controller. The first scanning device combines the vertical field of view and the horizontal field of view in the output light to create a two-dimensional light image of the content. The second scanning stage receives and directs the output of the first scanning stage toward a projected exit pupil.

    Abstract: A purpose of the present invention is to provide an image display apparatus and an image display element that are capable of achieving excellent visual effects. The image display apparatus of the present invention includes a first transparent member (30), a second transparent member (40), and an emission section (10). The first transparent member (30) includes a diffusion surface (31) for diffusing light incident on respective points. The second transparent (40) includes a control surface (41) and is integrated with the first transparent member (30), the control surface being disposed in a manner that the control surface faces the diffusion surface, controlling propagation directions of light diffused at the respective points on the diffusion surface, and forming a virtual image of the diffusion surface. The emission section (10) emits image light to the diffusion surface (31).

    Abstract: The present invention provides a pixel driving circuit, a display apparatus and a terminal. The pixel driving circuit includes: a light-emitting device, an enabling unit, a first transistor and a second transistor. When the light-emitting device illuminates, saturated current passing through the light-emitting device is relevant to the power voltage and the grayscale data voltage. Through embodiment of the present invention, saturated current passing through the driving transistor is relevant to the power voltage and the grayscale data voltage. Furthermore, both the power voltage and the grayscale data voltage are fixed values, that is, current passing through the light-emitting device is guaranteed to the constant. Therefore, current passing through the light-emitting device is no longer affected by the threshold voltage of the driving transistor and non-uniform pixel color could be avoided, accordingly, image uniformity of display with light-emitting device (e.g., OLED) raises, and so does display quality.
