An optical package element includes: an optical functional element having an optical functional surface; a packaging resin having light transmitting properties in which the optical functional element is embedded and whose surface facing toward the optical functional surface of the optical functional element is a light transmitting surface; conductive members connected to the optical functional element embedded in the packaging resin; and a light blocking layer provided on a surface of the conductive members facing toward the light transmitting surface.

Optical package element, display device, and electronic apparatus

A method for manufacturing a light-emitting diode display is provided. The method includes pre-fixing first, second, and third light-emitting diodes on a light emitting unit production substrate to produce light-emitting units each including first, second, and third light-emitting diodes, first electrodes of the first, second, and third light-emitting diodes being connected to a sub-common electrode. The method also includes transferring and fixing the light-emitting units from the light-emitting unit production substrate to a display substrate to produce a light-emitting diode display including the light-emitting units which are arranged in a first direction and a second direction perpendicular to the first direction (i.e., arranged in a two-dimensional matrix).

A cathode ray tube and a color selecting member, which can be manufactured without defects by using an existing projection aligner of a simple structure and can always produce a picture of high quality, in which phosphor layer has a pattern in stripes in the lateral direction of a screen, or in the horizontal direction and a color selecting member has slits elongated in the longitudinal direction of the screen, or in the horizontal scan line direction. Even in case of the thermal expansion of the color selecting member or a considerable longitudinal deviation between the exposure position at the time of manufacture and the position where an electron beam strikes in actual use, an electron beam can freely pass through the slits. Therefore, the accuracy of irradiation of the phosphor layer with the electron beam is not adversely influenced.

A capacitor for outputting a reference signal is formed by using a part of an envelope. A reference signal according to an anode voltage is output from the capacitor for outputting a reference signal. An unnecessary signal component included in an index-detection signal which is output via the capacitor for outputting an index signal is eliminated on the basis of the reference signal. With the configuration, only the required index-information signal is extracted from the index detection signal with high accuracy at a high SN ratio.

Cathode ray tube and signal detecting method in cathode ray tube

A technique is described for lightening a shadow of a damper line for preventing vibration of a color selecting member cast on a video screen and further preventing occurrence of the shadow. In a cathode ray tube in which electron beams emitted from neighboring electron guns cross each other before passing through a plurality of apertures of a color selecting member and has an area through which both of the electron beams pass. A damper line is provided in the area through which both of the electron beams pass. Since one of the electron beam falls on a shadow cast by the other electron beam, the shadow becomes lighter.

An image control device and method, and image display device, capable of producing an image of high quality by joining a plurality of divided frames with the joint areas made inconspicuous. An index electrode is provided in an over-scan region on the side of the joint area of the right and left divided frames. The index electrode outputs a detection signal in response to an electron beam scanning in the over-scan region. Based on the detection signal, obtained is data on a pixel position in the joint area of the divided frames. Further, based on the data on the pixel position thus obtained, estimated is data on a pixel position in an area other than the joint area of the divided frames. Meanwhile, using data obtained based on the detection signal outputted from the index electrode, control of image data is exerted so that the left and right divided frames are joined properly.
