    Abstract: [Problem] To provide a head-up display excellent in visibility. A light transmitting sheet 60 has an emission window portion 63 that has a pair of left and right sides 63L and 63R and a pair of front and rear sides 63Fr and 63Re, and is a region from which the display light is emitted, a light shielding frame portion 64 that is at least partially fixed to a case 52 and is an opaque region, and a check window portion 65 formed along the pair of left and right sides 63L and 63R and the pair of front and rear sides 63Fr and 63Re within the light shielding frame portion 64 and allowing visual recognition of presence or absence of the adhesive disposed between the case 52 and the light transmitting sheet 60. A check window 65L and 65R along the pair of left and right sides 63L and 63R or a check window 65Fr and 65Re along the pair of front and rear sides 63Fr and 63Re is such that the check window along one side has a smaller area than the check window along the other side of the pair.

    Abstract: A light-emissive module (114), typically utilizing one or more LEDs (132R, 132G, and 132B), is configured so that the maximum intensity of the module's light emission occurs along a direction (138) materially non-perpendicular to the back surface (136) of the module's supporting body (130). An active image-generating screen (102) contains a plurality of block facets (112), each containing a plurality of the light-emissive modules arranged so that their maximum light-intensity directions are largely the same. The block facets are configured to approximate a curved surface. The maximum light-intensity directions (158) of the block facets are thus materially slanted to one another. The image-generating screen presents a video image. A display system suitable for a motion simulator, such as a flight simulator, is formed by combining the screen with a reflective collimator (104).

    Abstract: A direct-viewing type display device 100a includes a display panel 100 having a display region 120 including pixels arrayed in a row direction and a column direction and a frame region 130 provided outside the display region, such that a first border line B1 and a second border line B2 exist between the display region and the frame region; and a light-transmitting cover 200 disposed on the viewer's side. The display region includes a peripheral display region 125 and a central display region 124; a third border line B3 and a fourth border line B4 exist between the peripheral display region and the central display region; the peripheral display region includes a first peripheral display section 121; the light-transmitting cover includes a lens portion disposed over the peripheral display region and the frame region; and the lens portion refracts light going out from a pixel 171 within the first peripheral display section in a direction X1 from a point where the third border line and the fourth border line intersect toward the pixel 171. According to the present invention, a display device is provided whose entire frame region including the corner portions can be obscured, such that joints can be obscured in the case of tiling.

    Abstract: A back-light module for an image scanning device includes a casing, a pair of tubular lamps, a light guide plate, and a frosted transparent plate. The image scanning device includes a document supporting plate and an optical scanning module movable in a longitudinal direction. A calibration of illumination with the back-light module is done by (1) activating the back-light module to project light onto the optical scanning module, (2) driving the optical scanning module in the longitudinal direction, (3) obtaining illumination signals associated with selected pixels of a longitudinally-extending calibration zone formed on the document supporting plate, (4) comparing each illumination signal with a reference to obtain a result and manipulating the result to obtain a calibration parameter, and (5) calibrating the illumination of pixels of an image with the corresponding calibration parameters in scanning a transmissive original document.
