Abstract:
A curved surface display device includes: a grayscale image projection device which projects a grayscale image; and a color filter disposed in front of the grayscale image projection device and having a desired curved shape. By disposing a color filter having a curved shape in front of a grayscale image projection device, a curved surface display device displaying color images can be realized through a simple structure.
Abstract:
The present invention relates to a method for synthesizing ramalin, and more particularly to a method for synthesizing ramalin, which comprises allowing 2-hydrazinylphenol to react with L-glutamic acid having a protected carboxyl group at C-1 and a protected amino group at C-2, and a method for preventing decomposition of the ramalin. According to the present invention, ramalin having excellent antioxidant and anti-inflammatory activities can be synthesized in high yield, and thus can be produced in large amounts. In addition, ramalin can be stably maintained for a long period of time, and thus can be easily used for industrial purposes.
Abstract:
Disclosed is a system and method for providing an in-room drinking water service at a hotel. The system includes a plurality of drinking water dispensers provided in guest rooms of the hotel. The system further includes a computer program running on one or more computers of the hotel and configured to manage the in-room drinking water service. In the system and method, when providing of the service in a particular guest room is confirmed, the computer program coordinates charging a fee to an account of the particular guest room for the service.
Abstract:
The present invention relates to a liquid crystal display device that prevents a color shift by allowing two sub-pixel areas to have the same transmittance. A liquid crystal display device according to the present invention includes a data line that includes: a connection portion having a direction of extension perpendicular to that of a gate line; a first portion oriented at a first angle with respect to a direction of extension of the connection portion; and a second portion oriented at a second angle different from the first angle with respect to the direction of extension of the connection portion, and wherein an angle between a rubbing direction of the liquid crystal and the connection portion satisfies θ L = θ 2 - θ 1 2 (where θL is the angle between the rubbing direction of the liquid crystal and the direction of extension of the connection portion, θ1: the first angle, θ2: the second angle).

Abstract:
A pair of scissors is disclosed. The scissors includes two members that are pivotally connected. Each member includes a blade and a shank. Each blade includes a proximal portion and a distal portion that is substantially bent from the proximal portion. The distal portion is sized so as to enter a human nostril in its entirety.
Abstract:
Disclosed are various methods of advertising one business (advertiser) using another business, which is a retail service or retail sales business, and is not an advertising service business or agent. Some embodiments involve distributing an advertising material of the advertiser to customers of the retail business. The advertising material includes a useful item and advertisement of the advertiser integrated in the useful item. The useful item induces the customers to keep the advertisement for a relatively long period. Some embodiments involve affixing advertisement of the advertiser onto an automobile of a customer of the retail business and providing a value to the customer to induce acceptance of affixing the advertisement.

Abstract:
In a test method of a display panel, a test signal and a test voltage are generated according to a test control signal. A display area of the display panel is tested based on the test signal and the test voltage. A driving voltage line and an on/off voltage line formed on the display panel are tested based on the test signal and the test voltage.
Abstract:
A heat exchanger for a refrigerator and a method for manufacturing a tube thereof with improved heat exchanger heat transfer efficiency. The heat exchanger for a refrigerator comprising of: a tube to guide a refrigerant; and a plurality of ridges disposed on an inner peripheral surface of the tube, the ridges configured to cause the refrigerant flowing along the tube to form a turbulent flow. The method of manufacturing a tube having a plurality of ridges comprising the steps of: providing a surface of a plate; forming ridges on the surface of the plate; and coupling opposite longitudinal edges of the plate such that the surface of the plate provided with the ridges becomes an inner peripheral surface of the tube.
