Publication number: 20170178577Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.Type: ApplicationFiled: March 9, 2017Publication date: June 22, 2017Inventors: Shoichi HIROTA, Shinichi KOMURA, Yoshifumi SEKIGUCHI, Tsunenori YAMAMOTO, Masaya ADACHI

Patent number: 9275575Abstract: When a previously existing technique is applied to a white OLED, such a structure is adopted that the peak wavelength of the intensity of interference is the emission peak wavelength corresponding to blue or less. However, in this case, the intensity of interference of the wavelength range corresponding to red is reduced to decrease the light emission intensity of red. A display device is configured in which a stacked film configuring a white light emitting element (an organic light-emitting diode element) is configured in such a manner that the peak wavelength of the intensity of interference is the peak wavelength of the light emission intensity corresponding to blue or less. The light emission intensity of the light emitting element corresponding to a red pixel is made greater than the light emission intensity of the light emitting elements corresponding to pixels for other colors.Type: GrantFiled: November 4, 2014Date of Patent: March 1, 2016Assignee: Japan Display Inc.Inventor: Masaya Adachi
