  • Patent number: 9843015
    Abstract: A light-emitting device having the quality of an image high in homogeneity is provided. A printed wiring board (second substrate) (107) is provided facing a substrate (first substrate) (101) that has a luminous element (102) formed thereon. A PWB side wiring (second group of wirings) (110) on the printed wiring board (107) is electrically connected to element side wirings (first group of wirings) (103, 104) by anisotropic conductive films (105a, 105b). At this point, because a low resistant copper foil is used to form the PWB side wiring (110), a voltage drop of the element side wirings (103, 104) and a delay of a signal can be reduced. Accordingly, the homogeneity of the quality of an image is improved, and the operating speed of a driver circuit portion is enhanced.

  • Patent number: 9837451
    Abstract: An EL display having high operating performance and reliability is provided. LDD regions 15a through 15d of a switching TFT 201 formed in a pixel are formed such that they do not overlap gate electrodes 19a and 19b to provide a structure which is primarily intended for the reduction of an off-current. An LDD region 22 of a current control TFT 202 is formed such that it partially overlaps a gate electrode 35 to provide a structure which is primarily intended for the prevention of hot carrier injection and the reduction of an off-current. Appropriate TFT structures are thus provided depending on required functions to improve operational performance and reliability.

  • Patent number: 9659524
    Abstract: An EL display device capable of performing clear multi-gradation color display and electronic equipment provided with the EL display device are provided, wherein gradation display is performed according to a time-division driving method in which the luminescence and non-luminescence of an EL element (109) disposed in a pixel (104) are controlled by time, and the influence by the characteristic variability of a current controlling TFT (108) is prevented. When this method is used, a data signal side driving circuit (102) and a gate signal side driving circuit (103) are formed with TFTs that use a silicon film having a peculiar crystal structure and exhibit an extremely high operation speed.

  • Publication number: 20170137930
    Abstract: An apparatus for forming a film having high uniformity in its film thickness distribution is provided. An evaporation source is used in which an evaporation cell, or a plurality of evaporation cells, having a longitudinal direction is formed, and by moving the evaporation source in a direction perpendicular to the longitudinal direction of the evaporation source, a thin film is deposited on a substrate. By making the evaporation source longer, the uniformity of the film thickness distribution in the longitudinal direction is increased. The evaporation source is moved, film formation is performed over the entire substrate, and therefore the uniformity of the film thickness distribution over the entire substrate can be increased.

  • Patent number: 9559302
    Abstract: An organic material for a light emitting device is deposited over a substrate by evaporating the organic material from an evaporation source. The evaporation source comprises a plurality of discrete evaporation cells separated from each other, wherein each of the plurality of discrete evaporation cells contains the organic material. The evaporation source has a length along a first direction and a width along a second direction orthogonal to the first direction, the length being greater than the width. The plurality of discrete evaporation cells is arranged along the first direction. When the organic material is evaporated, a relative location of the evaporation source with respect to the substrate is changed along the second direction, and the evaporation of the organic material is initiated by heating the plurality of discrete evaporation cells.
