Abstract: A gate driver can include a plurality of stages configured to output scan signals. An output of each stage among the plurality of stages is configured to connect to a pair of gate lines that are adjacent to each other, output an odd-numbered scan signal to an odd-numbered line among the pair of gate lines according to a first driving frequency, and output an even-numbered scan signal to an even-numbered line among the pair of gate lines according to the first driving frequency. Also, a phase difference between the odd-numbered scan signal and the even-numbered scan signal is 180 degrees.

Abstract: An optical compensation system includes a display device including a plurality of pixels, a first measurement unit configured to measure optical characteristics from an image displayed in a first area of the display device, a second measurement unit configured to measure optical characteristics from an image displayed in a second area of the display device, a driver configured to control at least one of the data voltage, the high voltage, and the low voltage of the display device to display an image, and a controller configured to detect a first low voltage optimized for pixels in the first area and a second low voltage optimized for pixels in the second area and to detect optical compensation values based on an image displayed by supplying the first low voltage to the pixels in the first area and supplying the second low voltage to the pixels in the second area.

The high strength fiber composite material includes: a high strength fiber material; and a resin film laminated on one surface of the high strength fiber material, wherein an amount of the resin film is 10 to 18 wt. % to a total weight of the high strength fiber material and the resin film, the resin film includes 20 to 70 wt. % of phenolic resin, 20 to 70 wt. % of polyvinyl butyral (PVB) resin, and the polyvinyl butyral (PVB) resin has a molecular weight of 30,000 to 120,000.

Abstract: Disclosed is a bulletproof material having superior bulletproof performance and enhanced back-side deformation characteristics along with superior wearing sensation due to relatively light weight and soft texture. The bulletproof material according to the present invention includes a fibrous layer including a carbon fiber network at a back side or near a back side.

Abstract: Disclosed are an airbag which can endure great external impact as well as high temperature and high pressure and is thus useful as an external airbag and a method for manufacturing the same. The airbag includes: a fabric containing an aramid fiber having an young's modulus of 600 to 1000 g/d and a tenacity of 20 to 30 g/d, and having a cover factor of 1500 to 2100, and a coating layer formed on the surface of the fabric, wherein a seam strength of an adhered member measured in accordance with ASTM D 1683 is 200 to 600 kgf/20 mm.

Abstract: A mobile communication terminal with dedicated keys for controlling an integrated functional component such as an audio player, in which the dedicated keys are situated at convenient positions for use. The mobile communication terminal includes a housing that accommodates parts which enable wireless communications with an external device and has an audio player therein. The terminal includes a control key assembly positioned on at least one lateral side of the housing to enable a user to operate the audio player. The position of the control key assembly assists the user in pressing the keys using his thumb, forefinger, middle finger and third finger. The position of the control key assembly also enables a wide auxiliary display to be positioned on the upper surface of the housing, e.g., on the outer surface of the upper housing.

Abstract: A domain-divided twisted nematic crystal cell and method of fabricating thereof. The method of the present invention comprises the steps of providing first and second substrates, forming a photo-alignment layer in each domain of the first substrate having two or more domains, wherein thicknesses of the photo-alignment layers corresponding to the domains are different from each other. A pretilt angle in each domain is formed by light irradiation on the photo-alignment layer, wherein the pretilt angles corresponding to the domains are different from each other due to the different thicknesses of the photo-alignment layer in different domains. The first and second substrates are positioned to face each other, and liquid crystal is injected between the first and second substrates.
