  • Patent number: 11138929
    Abstract: A display device includes a pixel including a light emitting element connected to a scan line and a data line; a driving transistor that controls a driving current supplied to the light emitting element according to a data voltage applied from the data line. The driving transistor includes a first semiconductor layer, and a first gate electrode disposed on the first semiconductor layer. The display device includes a switching transistor that applies the data voltage to the driving transistor according to a scan signal applied to the scan line. The switching transistor includes a second semiconductor layer, and a second gate electrode disposed on the second semiconductor layer. The display device includes a light blocking layer and a first buffer layer disposed at a lower portion of the driving transistor. The light blocking layer and the first buffer layer do not overlap the switching transistor.

  • Patent number: 10715797
    Abstract: The present invention relates to a device for testing an angle of view of a camera. The present invention may comprise: a first light source which is arranged to face an image sensor, and has a first width and a second width longer than the first width; and a second light source and a third light source which are disposed on both sides of the image sensor in the direction of the first width, respectively. The present invention can inhibit an interference of the light source or a bracket supporting the light source by reducing the number of light sources. In addition, since it is possible to measure the angle of view of a camera by reducing the light sources, the present invention can reduce the manufacturing costs of a device for testing an angle of view of a camera.

  • Patent number: 9096797
    Abstract: A silicate phosphor composition is provided having a ?-phase of an orthorhombic crystal structure whose space group is Pbnm 62, and whose composition is represented by the following chemical formula: Ca2-x-y-zMxSiO4:yCe3+,zN(0?x<0.5,0<y?0.1,0?z<0.15) In the formula, M represents at least one member selected from the group consisting of Mg, Sr, Ba, Zn, Na, Al, Ga, Ge, P, As and Fe, and N represents at least one member selected from the group consisting of Eu2+, Mn2+, Tb3+, Yb2+ and Tm3+. The silicate phosphor has a maximum absorbance for a wavelength of about 450 nm to about 475 nm corresponding to a main part of a blue excitation light, and has a great stability at a high temperature. As such the silicate phosphor may be used in combination with a blue light source to produce a white light.
