A complementary metal oxide semiconductor (CMOS) image sensor includes a photodiode, a switch and a comparator. The switch transfers a sensing signal to a sensing node from the photodiode. The comparator, which is directly connected to the sensing node, compares the sensing signal of the sensing node with a reference signal. The comparator outputs a signal corresponding to a voltage difference between the sensing signal and the reference signal.

Provided is a pixel circuit in a CMOS image sensor, a structure thereof, and a method of operating the same. The pixel includes: a photodiode; a floating diffusion node connected to the photodiode through a first switch; a source follower responsive to a voltage of the floating diffusion node. The voltage of the floating diffusion node is applied to the source follower through capacitance coupling.

The present invention provides a printing head for nano patterning including a manifold for accommodating a liquid printing material, a cartridge with an injection chamber communicating with the manifold, and a sample holder for patterning installed outside the injection chamber of the cartridge. The printing head comprises a shadow mask which is installed outside the injection chamber to be finely moved in an X-Y direction and has a single injection hole with a relatively very small size; an actuator for finely moving the shadow mask; an injection-inducing unit including a high voltage generator, a power supply electrode that is installed within the injection chamber and receives power from the high voltage generator to generate positive charges, and an opposite electrode for generating negative charges on the sample holder in a state where the shadow mask is interposed between the power supply electrode and the opposite electrode, thereby generating induced discharge from the injection chamber toward the sample holder; and a control unit for controlling the driving of the actuator so that the injection hole of the shadow mask can be moved to patterning positions corresponding to patterning data input in advance. According to the present invention, patterning accuracy can be improved, ultra-fine patterning and patterning of arbitrary shapes can be achieved, and a configuration for injecting the printing material can be simplified.

The present invention relates to a luminous advertisement sheet. The luminous advertisement sheet includes a light-transmitting print sheet having an EL advertisement region formed in at least one area of the print sheet, and a general advertisement region formed in the other area thereof. The EL advertisement region has at least one of a fixed pattern portion in which a transparent electrode layer, an EL layer and a dielectric layer are sequentially laminated and a variable pattern portion in which a transparent electrode layer, an EL layer, a dielectric layer and a plurality of pixel electrode layers are sequentially laminated. The general advertisement region allows general dye printing to be performed therein. The luminous advertisement sheet further includes a pattern electrode layer laminated and printed with a conductive ink material to have a predetermined luminous pattern in at least one area of the dielectric layer laminated in the fixed pattern portion and/or the variable pattern portion. Accordingly, there are provided a luminous advertisement sheet that exhibits excellent advertisement effects and can be easily produced in a multi-line small-batch production manner and at remarkably reduced manufacturing costs, and a method of manufacturing the same.

Disclosed herein is a method and apparatus for manufacturing an electronic device, which is intended to economically manufacture an electronic circuit device, such as an IC chip, using functional ink and a roll-to-roll rotary pressing process. The method includes a first step of injecting functional ink into a forming groove of a forming roll, a second step of removing ink covering a surface of the forming roll, a third step of drying a surface of the functional ink injected into the forming groove, a fourth step of transferring the dried surface of the functional ink to a printing roll, a fifth step of drying another surface of the functional ink transferred to the printing roll, a sixth step of transferring the functional ink from the printing roll to flexible printing paper which is unwound from a winding roll, and a seventh step of winding the printing paper, on which an electronic circuit is printed, around a rewinding roll.

A gas scrubber with an automatic disassembling device in accordance with the present invention comprises a burning chamber to treat the gas with heat, a wetting chamber connected to the burning chamber for removing water soluble components contained in the gas flowing in from the burning chamber, an outlet which exhausts gas that has been treated, and a housing that contains both the burning chamber and the wetting chamber, wherein said wetting chamber slides out of the housing along guide rails placed at the bottom side edges of the wetting chamber. The bottom back edge of the burning chamber is connected to the top back edge of the wetting chamber with a hinge and a pivot member is placed on both sides of the burning chamber so that when the wetting chamber slides out along the guide rail to the outside to the housing, the burning chamber rotates about 90 degrees in the inside of the housing.
