PURPOSE: A diffusion ink composition for patterning a light guide plate of a back light unit is provided to improve luminance and ink printing ability by using a nano dispersion technology. CONSTITUTION: A diffusion ink composition for patterning a light guide plate of a back light unit comprises 40-55 weight% of solvent, 10-15 weight% of inorganic nanoparticles(22), 10-20 weight% of polymethylmethacrylate beads, 20-30 weight% of acrylic copolymer(21) containing methylmethacrylate, 1-15 weight% of additive based on the total weight of the diffusion ink composition. The inorganic nanoparticles are manufactured by a liquid-chemistry method, and have an average particle diameter of 0.1-10 microns. The additive is one or more selected from a diluent, a dispersant, a silicon antifoaming agent, and a leveling agent.
Abstract:
The present invention relates to an indoor ornamental plant cultivation device including a stand portion where a plurality of cultivation ports are arranged in a circumference; a lighting unit that emits a light source toward the cultivation ports from above the stand portion; and an ultrasonic wave humidification device that is disposed on an upper side of the lighting unit to generate cloud and mist and supply moisture to the cultivation port. The lighting unit that is capable of plant cultivation is disposed in the stand portion where the plurality of cultivation ports are arranged in a circular manner to be used as mood light. The ultrasonic wave humidification device that is disposed can be used as a moisture supply and indoor humidity adjusting device required for plant cultivation to provide fresh indoor environments. In addition, the present invention uses a home-use LED light source as the lighting unit, and thus plant cultivation is available at night as well as indoors where natural light is unavailable. Accordingly, sprout vegetable can be grown to be provided as food, and the lighting unit can be utilized as mood light. In addition, the present invention can provide the optimum conditions for plant cultivation because the LED light source having a wavelength range suitable for growth conditions of a cultivated plant is selectively used and replaced.

Abstract:
The present invention relates to an apparatus for cleaning an LCD glass substrate including a cassette loading part, multiple alkali vessels, a deionized water cleaning vessel and a cassette unloading part. The alkali vessel is installed with a cleaning solution circulating device for circulating an alkali aqueous solution forcibly from the top to the bottom, a cleaning solution heating unit for heating the alkali aqueous solution and an overflow recovery device for removing bubbles generated in the alkali vessel. The present invention circulates the alkali aqueous solution in the alkali vessel using a circulation pump and also removes the generated bubbles through the overflow recovery device, and can improve detergency of the LCD glass substrate by heating the alkali aqueous solution by a fixed temperature using the cleaning solution heating unit. The present invention also can minimize defects such as protrusion defects in foreign substances of the LCD glass substrate in etching the LCD glass substrate, and can increase marketability by increasing etching uniformity. The present invention also has eco-friendly effect by reducing generation of a wasted alkali solution maximally, by filtering the foreign substances in the alkali solution and reusing the alkali solution by adding a recycling system.
