A display panel and a method of fabricating the same are provided. The display panel includes: a base substrate; a first electrode disposed on the base substrate; a hole injection layer disposed on the first electrode, wherein a surface of the hole injection layer away from the first electrode is scattering surface. In the present invention, the surface of the hole injection layer away from the first electrode is set as the scattering surface, and changes of brightness and chromaticity caused by a change of viewing angles is weakened by the scattering surface, thereby expanding viewing angles of the display panel.

Disclosed is a workpiece processing apparatus that performs a predetermined processing on a workpiece. The workpiece processing apparatus includes: a workpiece table configured to place the workpiece thereon; a processor configured to process the workpiece placed on the workpiece table; a movement mechanism configured to relatively move the workpiece table and the processor; a position measuring device configured to measure a position of the movement mechanism; a detector configured to detect a position of the workpiece placed on the workpiece table; and a corrector configured to calculate a positional correction amount of the workpiece table based on a measurement result of the position measuring device and a detection result of the detector.

Provided are a display substrate, a preparation method thereof, and a display apparatus. A portion of a pixel definition layer that is in contact with a light-emitting functional layer is configured to have the performance of switching between hydrophilicity and hydrophobicity when an external condition changes. When film layers of the light-emitting functional layer are formed, due to the inconsistent hydrophilicity or hydrophobicity of the film layers of the light-emitting functional layer, when a hydrophilic light-emitting functional layer is formed, the pixel definition layer switches, under processing via the external condition, the portion of the pixel definition layer that is in contact with the light-emitting functional layer to be hydrophobic, and when a hydrophobic light-emitting functional layer is formed, the pixel definition layer switches, under processing via the external condition, the portion of the pixel definition layer that is in contact with the light-emitting functional layer to be hydrophilic.

A display device includes a base layer, a first electrode on the base layer, a pixel-defining layer in which an opening exposing an upper surface of the first electrode is defined, a protective layer overlapping the pixel-defining layer and between the pixel-defining layer and the first electrode, a functional layer on the first electrode in the opening, an auxiliary electrode on an upper surface of the pixel-defining layer, and a second electrode on the functional layer and the auxiliary electrode.

Methods of modulating flow during vapor jet deposition of organic materials are provided. A method may include ejecting a vapor entrained in a delivery gas from a nozzle onto a substrate upon which the vapor condenses. A confinement gas may be provided that has a flow direction opposing a flow direction of the delivery gas ejected from the nozzle. A vacuum source may be provided that is adjacent to a delivery gas aperture of the nozzle. The method may include adjusting, by an actuator, a fly height separation between a deposition nozzle aperture of the nozzle and a deposition target.

A method for manufacturing a photoelectric conversion element includes providing a base structure including a semiconductor substrate having a principal surface, a first electrode located on or above the principal surface, second electrodes which are located on or above the principal surface and which are one- or two-dimensionally arranged, and a photoelectric conversion film covering at least the second electrodes; forming a mask layer on the photoelectric conversion film, the mask layer being conductive and including a covering section covering a portion of the photoelectric conversion film that overlaps the second electrodes in plan view; and partially removing the photoelectric conversion film by immersing the base structure and the mask layer in an etchant.

A printer deposits material onto a substrate as part of a manufacturing process for an electronic product; at least one transported component experiences error, which affects the deposition. This error is mitigated using transducers that equalize position of the component, e.g., to provide an “ideal” conveyance path, thereby permitting precise droplet placement notwithstanding the error. In one embodiment, an optical guide (e.g., using a laser) is used to define a desired path; sensors mounted to the component dynamically detect deviation from this path, with this deviation then being used to drive the transducers to immediately counteract the deviation. This error correction scheme can be applied to correct for more than type of transport error, for example, to correct for error in a substrate transport path, a printhead transport path and/or split-axis transport non-orthogonality.

The present specification relates to an ink composition comprising a solvent comprising a solvent represented by Chemical Formula 1, a solvent represented by Chemical Formula 2 and a solvent represented by Chemical Formula 3; and a charge transferring material or a light emitting material, and a method for manufacturing an organic light emitting device formed using the ink composition.
