A display device may include a pixel, an emission control driver, and a timing controller. The emission control driver may supply an emission control signal set for controlling emission periods of the pixel. The timing controller may receive a received bit stream that includes a first bit set and a second bit set, may determine a first duty ratio of the emission control signal set using bits of the first bit set without using any bit of the second bit set. The first bit set may include at least two bits. The second bit set may include at least one bit. The emission control signal set may control the pixel to operate according to the first duty ratio for each frame of a first frame group.

Display device and operating method thereof

In a display device including pixels that are coupled to data lines, that are supplied with a data signal during a display period, and that are configured to emit light corresponding to the data signal during a bias period, the display device includes a source capacitor coupled to each of the data lines, and a data driver configured to supply the data signal during the display period, to supply a bias signal during a first period in the bias period, and to not supply the bias signal during a second period.

A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

Lyocell material for tobacco filter

This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.

Modified cross-section lyocell material for tobacco filter, and preparation method therefor

Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.

Lyocell material for cigarette filter and method for preparing same

This invention relates to a method of manufacturing a lyocell material for a cigarette filter, including (S1) spinning a lyocell spinning dope composed of 8 to 13 wt % of a cellulose pulp and 87 to 92 wt % of an N-methylmorpholine-N-oxide (NMMO) aqueous solution; (S2) coagulating the lyocell spinning dope spun in (S1), thus obtaining a lyocell multifilament; (S3) water-washing the lyocell multifilament obtained in (S2); (S4) oiling the lyocell multifilament water-washed in (S3); and (S5) applying steam and pressure to the lyocell multifilament obtained in (S4), thus obtaining a crimped tow having 30 to 40 crimps per inch.

Method of manufacturing a lyocell material for a cigarette filter

This invention relates to a lyocell material for a cigarette filter and a method of manufacturing the same, wherein the lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to thus obtain a crimped tow.

Lyocell material for tobacco filter and method for preparing same

Disclosed herein is a method for preparing a cellulose-based film from raw material pulp, the method including the steps of: preparing a dope from a composition comprising 5-15 wt % of a pulp having an alpha-cellulose content of more than 90% and 85-95 wt % of an aqueous N-methylmorpholine-N-oxide solution; extruding the dope from a die onto a running support; casting the extrudate to form a sheet-shaped material; washing the cast sheet with water to remove N-methylmorpholine-N-oxide therefrom; and drying the washed sheet. The method enables the cellulose-based film to be prepared from environmentally friendly wood pulp through an environmentally friendly process.
