The upper reflection polarizer is configured such that a regularly arranged metallic lattice is formed on a support this LCD device may give a good mirror effect when power is intercepted, and also give a clear display with high brightness even at a bright place when power is supplied to operate the LCD device. | 01-28-2010 |
| 20100027146 | METHOD FOR MANUFACTURING COLOR FILTER AND COLOR FILTER MANUFACTURED BY THE SAME - The present invention relates to a method of manufacturing a color filter, which includes forming a light-shielding portion and a pixel portion on a substrate, and reforming the pixel portion to be ink-philic by using a laser ablation. In the method of manufacturing the color filter, the laser ablation is used to prevent ink particles from being agglomerated in the pixel portion, uniformly filling with the ink, and selectively performing surface reformation of the pixel portion. The color filter manufactured by using the method has desirable pixels without color mixing. | 02-04-2010 |
| 20100085624 | Apparatus for driving electrochromic device and method thereof - An apparatus for driving an electrochromic device (ECD) includes a driving volt age output unit for selectively applying a coloring or decoloring voltage between upper and lower electrodes of an ECD; a timer for counting an applying time of the coloring or decoloring voltage in a memory type driving mode and then outputting a voltage application completion signal after the counted time exceeds a preset time, the timer bypassing the counting operation in a non-memory type driving mode; and a driving controller for selectively inputting a coloring or decoloring signal to the driving voltage output unit such that the driving voltage output unit is controlled to output a coloring or decoloring voltage corresponding to the signal, the driving controller receiving the voltage application completion signal to stop the input of the coloring or decoloring signal. Thus, memory type and non-memory type ECDs may be driven automatically using only one apparatus. | 04-08-2010 |
| 20100279233 | METHOD FOR LASER INTERFERENCE LITHOGRAPHY USING DIFFRACTION GRATING - A method for laser interference lithography using a diffraction grating includes (a) forming a photoresist layer on a work substrate to which a repeated fine pattern is to be formed; (b) forming a refractive index matching material layer on the photoresist layer; (c) forming on the refractive index matching material layer a diffraction grating layer having a period of diffraction grating within the range from λ/n | 11-04-2010 |
