Abstract: Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.

Abstract: The present specification discloses a pixel driving circuit having a reduced number of external contacts. A conventional digital driving pixel requires two contacts (Vcc, GND) related to power, a contact (row signal, column signal) for inputting two signals for digital driving, a contact (mode selection) for inputting a set value required for driving the pixel, and a contact (reset) for maintaining video data for one frame to implement a cycle function during PWM driving and for inputting a reset signal to clear previous video data before inputting new video data. However, the higher the number of contacts, the lower the efficiency of pick & place in the manufacturing process. Thus, in the present specification, a pixel driving circuit is proposed, which can be digitally driven even when the number of contacts is reduced through combination of a row signal and a column signal.
