  • Patent number: 10170533
    Abstract: A display device including a pixel array unit having a matrix of pixels each configured such that an anode electrode of an organic electroluminescent element is connected to a source electrode of a drive transistor, a gate electrode of the drive transistor is connected to a source or drain electrode of a writing transistor, and a storage capacitor is connected between the gate and source electrodes of the drive transistor, scanning lines and power supply lines for individual pixel rows, and signal lines for individual pixel columns. A video signal reference potential is supplied to the signal lines for a period during which a scanning signal is supplied to the scanning lines during driving of pixels in a preceding row. During threshold correction for the drive transistor in a current pixel, the video signal reference potential and a potential of the cathode electrode of the organic electroluminescent element are equal.

  • Publication number: 20180301086
    Abstract: A display panel including pixels disposed on a substrate, where each of the pixels includes a light emitting element, and a capacitor. The capacitor of a first one of the pixels is partially overlapped, in a vertical direction, by respective pixel areas of two of the pixels. The anode of the capacitor of the first one of the pixels may be disposed closer to the substrate than a cathode of the capacitor, thereby reducing a parasitic capacitance between the capacitor and an anode of the light emitting element of one of the two pixels overlapping the capacitor.

  • Publication number: 20180254305
    Abstract: A self-light emitting display unit capable of improving manufacturing yield is provided. Sizes of color pixel circuits corresponding to pixels for R, G, and B are respectively set unevenly within a pixel circuit according to a magnitude ratio of drive currents which allow color self-light emitting elements in the pixel to emit with a same light emission luminance. Thereby, the pattern densities of color pixel circuits respectively corresponding to the pixels for R, G, and B become even to each other, and the pattern defect rate as the whole pixel circuit is decreased.

  • Publication number: 20180164736
    Abstract: A slit nozzle is moved by a nozzle lifting/lowering mechanism and a nozzle sliding mechanism relative to substrates held in a substantially horizontal attitude by spin chucks. A development liquid is discharged on each substrate from a discharge port of the slit nozzle such that development processing for the substrate is performed. After the development liquid is discharged, the slit nozzle is moved to a waiting position excluding positions over the substrates held by the spin chucks. In waiting pods provided at the waiting positions, cleaning processing for the slit nozzle is performed by a cleaning liquid with gas bubbles mixed therein.

  • Publication number: 20170270866
    Abstract: A display device of the disclosure includes a plurality of pixels and a driver. The driver unit makes scanning of pixels that belong to a plurality of pixel lines out of the plurality of pixels, in units of pixel line groups each of which is constituted by a predetermined number of the pixel lines, in a scanning order indicated by scanning ordinal numbers associated with the respective pixel line groups, to perform a write drive that includes writing a pixel voltage to each pixel. The scanning ordinal numbers are set to allow a sum of the scanning ordinal numbers of any two adjacent pixel line groups to approximate to a predetermined value.
