Provided is a microcapsule patterning method for patterning electrophoretic microcapsules on a substrate, the method including the steps of: preparing a microcapsule slurry in which microcapsules and a water-soluble binder are mixed; putting the microcapsule slurry into a liquid ejector having injection and ejection ports formed therein; and applying the microcapsule slurry contained in the liquid ejector onto the substrate so as to pattern pixels using the microcapsules. Accordingly, specific patterns are formed without physical and chemical damage to the microcapsules. Therefore, the patterns can be used as pixels of flat panel displays. Further, through the patterning, it is possible to implement a color display device which does not exhibit performance degradation

Provided are a touch screen and a method of operating the same. The touch screen includes a detecting part, a control part, and a tactile feedback part. The detecting part detects object's approach or contact. The control part receives a signal of the detecting part to output a feedback signal. The tactile feedback part receives the feedback signal of the control part to provide a tactile feedback to a contact position using a magnetic force. The tactile feedback uses the magnetic force of a magnetic dipole.

Provided are a device for depositing an organic/inorganic thin film and a deposition method thereof. The method includes: i) heating a source vessel containing an organic material and an inorganic material to generate at least one deposition gas phase of the organic and inorganic materials; ii) transferring one of the deposition gas phases of the organic and inorganic materials to a process chamber through a transfer path maintaining a constant temperature so as to prevent the generated deposition gas phases of the organic/inorganic materials from being condensed; iii) distributing one of the deposition gas phases of the organic and inorganic materials transferred to the process chamber onto a substrate disposed in the process chamber to adsorb one of the organic and inorganic materials on the substrate; iv) purging the process chamber using a diluted gas and a transfer gas after one of the organic and inorganic materials is adsorbed on the substrate; v) heating an activating agent source vessel containing an activation heat initiator capable of activating a monomer of one of the deposition gas phases of the organic and inorganic materials to generate a heat initiator gas phase; vi) transferring the heat initiator gas phase to the process chamber through a transfer path maintaining a constant temperature so as to prevent the heat initiator gas phase from being condensed; vii) distributing the heat initiator gas phase transferred to the process chamber onto the organic or inorganic material monomer deposited on the substrate through the process chamber maintaining a constant temperature so as to prevent the heat initiator gas phase from being condensed in a shower head, and forming an organic/inorganic thin film; and viii) exhausting the heat initiator gas phase remaining after the organic/inorganic thin film is deposited on the substrate from the process chamber, and purging the process chamber using the diluted gas and the transfer gas. Therefore, according to the method of depositing the organic/inorganic thin film in a time-division manner, the thickness of the thin film can be accurately adjusted and the deposition can be uniformly performed when the thin film is deposited on a large-scale substrate.

Methods of manufacturing metal oxide nanoparticles are provided. The method uses a bubble generation ultrasonic synthesis method. A gas is injected into a metal oxide preliminary composition solution to promote length growth of nanoparticles. After a basic chemical species solution is mixed with the metal oxide preliminary composition solution, ultrasonic waves are applied to form a reactant. The reactant is refined to manufacture metal oxide nanoparticles. The nanoparticles may have excellent dispersibility and a uniform thin film may be formed by the nanoparticles.
