Abstract: An organic film is patterned without applying a hard mask or photolithography. A hydrophilic solvent-soluble resist is placed and arranged on the organic film using a non-lithography process. The hydrophilic solvent-soluble resist is placed and arranged using a printing or lamination process. The organic film is patterned using a wet etchant that is selective to the organic film but non-selective to the hydrophilic solvent-soluble resist. The hydrophilic solvent-soluble resist protects the underlying organic film from contamination and damage, prevents undercutting, and assists in providing a desired taper profile during patterning.

Abstract: This disclosure provides systems, methods and apparatus for OLED control circuits. In some implementations, the OLED control circuit can be configured to reverse the bias of the OLED without the use of a dedicated initialization voltage. A low voltage data signal applied on a data line can be used to drain voltage from the anode of the OLED through a diode-connected transistor. A high voltage data signal applied on the same data line can be used to store a reference voltage on a storage capacitor, where the reference voltage is also a function of the threshold voltage of a driving transistor of the OLED control circuit. The stored reference voltage can be used to compensate for the threshold voltage of the driving transistor when the OLED is energized by a current, so that the current is independent of the threshold voltage of the driving transistor.

Abstract: This disclosure provides apparatuses and methods of manufacturing apparatuses including thin film transistors (TFTs) and storage capacitors. An apparatus can include a substrate, a TFT, a storage capacitor adjacent to the TFT, and a common electrode. The storage capacitor can be substantially transparent to increase aperture ratio of a display device. The storage capacitor can include an insulating layer between a first transparent electrode and a second transparent electrode. The TFT can include a gate electrode, a gate insulating layer, an oxide semiconductor, source and drain electrodes, and a dielectric layer. The oxide semiconductor can be formed out of the same layer as the first transparent electrode, and the common electrode can be formed out of the same layer as the oxide semiconductor or the source and drain electrodes.

Abstract: An electrochromic component (3) generally includes: a first electrode (30), an opposite second electrode (32); a electrically conductive polymer layer (34) provided on the second electrode and facing the first electrode; and a gas chamber (36) for receiving a working gas (40), the gas chamber being defined between the first and second electrodes. The working gas is capable of having an electrochromic reation with the polymer layer under an electric field applied by the first and second electrodes. The polymer layer may be made of at least one material chosen from the group of polyacetylene, polypyrrole, and polyaniline. The working gas may be one of an oxidizing gas and a reducing gas. For example, the working gas can be oxygen gas or hydrogen gas. Advantageously, the gas chamber includes a working gas inlet and a working gas outlet.

Abstract: An anti-fingerprint coating construction (23) for application to a surface of a substrate (21) includes a layer formed of a material selected from the group consisting of a hydrophobic nano-composite material, an oleophobic nano-composite material, and a super-amphiphobic nano-composite material. When the anti-fingerprint coating construction is employed on a metal surface or a nonmetal surface, sweat or/and grease on fingers of a user is not liable to be adhered to the surface. Therefore a fingerprint of the user is prevented from being imprinted on the surface, and the surface can remain clean and aesthetically pleasing. Because the anti-fingerprint coating construction is easy to clean, the anti-fingerprint coating construction has good anti-corrosion and antibacterial properties. The anti-fingerprint coating construction contains no chromium, and therefore does not need to be processed by an acid or alkali solution. This makes the anti-fingerprint coating construction environmentally friendly.
