摘要:
A method and apparatus for driving the data in a liquid crystal display (LCD) panel are presented. The method and apparatus prevent or reduce defects at the boundary between pixel blocks when the pixel blocks are sequentially driven on a block-by-block basis. The method includes applying data signals to a first data block, precharging a second data block that is adjacent to the first data block to a predetermined precharge voltage, and applying data signals to the second data block. The precharging prevents a large voltage difference at the boundary, thereby reducing defects.

Disclosed herein is a photoresist composition suitable for coating onto a large substrate and having improved coating uniformity to prevent occurrence of stains, a coating method thereof, a method of forming an organic film pattern using the same, and a display device fabricated thereby. The present invention thus provides a photoresist composition comprising a polymeric resin with an incorporated polysiloxane resin, a photosensitive compound, and an organic solvent. Accordingly, the photoresist composition can be coated onto a large substrate by a spinless coating method, and thereby coating uniformity can be improved, the occurrence of stains such as cumulous stains and resin streaks can be prevented, and the coating rate and quality of a final product prepared using the photoresist composition can also thereby be enhanced.

The present invention provides a method for calculating a destruction rate of refrigerant by establishing a calibration line using standard refrigerant gases and measuring the amount of refrigerant remaining in exhaust gas discharged after destruction of waste refrigerant. For this purpose, the present invention provides a method for calculating a destruction rate of refrigerant, the method including: establishing a calibration line using standard refrigerant gas samples whose concentrations are known; sampling exhaust gas finally discharged after decomposition of waste refrigerant; measuring the concentration of refrigerant remaining in the sampled exhaust gas; and calculating the amount of undestroyed refrigerant using the concentration of refrigerant remaining in the exhaust gas, the amount of exhaust gas discharged, and the known density of refrigerant.

Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.
