    Abstract: An electronic device display may have an organic light-emitting diode layer that emits light to form images for a user. Reflective structures such as metal signal lines may be present in the organic light-emitting diode layer. Ambient light reflections from the metal signal lines may be suppressed using a circular polarizer on the organic light-emitting diode layer. To increase light emission efficiency from the organic light-emitting diode display layer under low ambient light conditions in which ambient light reflections are not significant, the polarization efficiency of the circular polarizer may be reduced. Control circuitry may make measurements of ambient light intensity using an ambient light sensor and can control the polarization efficiency of the circular polarizer accordingly by applying adjustable amounts of light or electric field. Polarization efficiency may also be adjusted using a photosensitive polarizer material that responds directly to changes in ambient light level.

    Abstract: An electrically programmable reticle is made using at least one electrochromatic layer that changes its optical transmissibility in response to applied voltages. Transparent conductor layers are configured to the desired patterns. The electrically programmable reticles are either patterned in continuous forms that have separately applied voltages or in a matrix of rows and columns that are addressed by row and column selects such that desired patterns are formed with the application of a first voltage level and reset with the application of a second voltage level.

  • Patent number: 6940581
    Abstract: An image medium is attached in an image input unit of a printing system, and an image to be printed and its number of prints are set through an operation panel. As contents of an order is determined, a credit card is inserted in an ID reading unit, and the printing system identifies a customer, and registers the order, then settles a payment. If the payment is done in cash, the printing system issues a magnetic card and the like on which a number is recorded for the customer to verify. The printing system has a plurality of container boxes for storing the printed material related to the customer's order by separating and keeping the printed material for each customer. A host unit verifies the properness of the person who comes to receive the prints by his/her credit card or the magnetic card and the like, and opens a corresponding outlet among the container boxes, so that the customer can receive his/her prints.

  • Patent number: 6744512
    Abstract: An object of the invention is to provide a position measuring apparatus which can measure position information of a mark formed on an object with high accuracy, and an exposure apparatus which can perform exposure by performing alignment highly accurately, based on the highly accurate position information measured by the position measuring apparatus, and as a result, can realize fine processing. In order to achieve the object, the present invention is a position information measuring apparatus for measuring position information of an alignment mark, by converting an image Im1 of an alignment mark formed on an image pickup plane F1 of an image pickup device into image information, while scanning the image Im1 in a scanning direction SC1, and performing calculation processing with respect to the obtained image information, wherein the measuring direction D11 of the image Im1 of the alignment mark is set so as to be orthogonal to the scanning direction SC1.

    Abstract: The invention relates to a system for projecting or displaying images comprising a valve exhibiting a plurality of image-forming elements having a light transmission coefficient which can be controlled so as to present the image, and a means of illuminating the valve comprising a light source and an integrator having two lens arrays associated in such a way that each lens of the second array distributes over the valve the light received from a corresponding lens of the first array. This system comprises a means for focusing the illuminating beam onto the integrator. The dimensions of the integrator are thus minimized. The focusing means comprises, for example, a reflector which reflects the light produced by the source, the integrator being arranged substantially in the focal plane of the reflector.

  • Patent number: 6456359
    Abstract: A PBS for guiding light from a light source to a DMD as light modulating means as well as for guiding light modulated by the DMD to photographic paper is provided on an optical path between the light source and the DMD. The DMD is arranged so that light from the PBS perpendicularly enters itself, and is equipped with a plurality of micromirrors which swing in accordance with image data. This arrangement allows optical components to be disposed so that an angle of incidence of light with respect to the DMD is 0°, thereby enabling tight layout of the light source section. In other words, there is no need to spread the optical components around the light modulating means like in the conventional cases where an angle of incidence with respect to the light modulating means is more or less required.
