Abstract: A liquid crystal display device includes a liquid crystal panel having a plurality of gate lines, a plurality of data lines, a liquid crystal element and a memory element. A mode conversion unit converts a mode of the liquid crystal panel to a normal mode or a power saving mode. A timing controller drives the liquid crystal panel in either mode and outputs gate driving information and image data. A data driver transmits the image data from the timing controller to the plurality of data lines. A gate driver decodes the gate driving information input from the timing controller to generate a gate driving signal and outputs the gate driving signal to the plurality of gate lines.

Abstract: A wet etching apparatus and method to shorten processing time and to eliminate formation of unintended mask pattern are described. In the conventional art, after a mask pattern is formed, alien substances such as water mist or stain are left on the substrate. The alien substances act as an etching block in the wet etching process. This generates an unintended mask pattern. The present invention uses ultraviolet light to remove the alien substances prior to the etching process. When the alien substances are removed, the intended mask pattern is generated after the etching process. The wet etching device according to the present invention includes an ultraviolet cleaner and a conveyor to convey substrates to and from the ultraviolet cleaner. Spaces for the ultraviolet cleaner and the conveyor are created in the wet etching apparatus by reducing space for cassettes and reducing space required by the loader. As a result, alien substances can be removed without the need for separate sets of equipment, which reduces processing time, simplifies the process, and increases both productivity and reliability.

Abstract: A liquid crystal display (LCD) realizes a high brightness by using cholesteric liquid crystal (CLC) in a color filter and a polarizer, and improves viewing angles by using a hologram diffuser. The LCD includes a back light unit to produce and supply light, and a collimating sheet to collimate the light supplied by the back light unit. A CLC polarizer transmits left-circularly polarized light from the collimating sheet, and reflects other light. A lower substrate is disposed above the CLC polarizer, and an upper substrate is disposed above the lower substrate and includes a holographic diffuser which diffuses light without altering a polarization of the light. A liquid crystal layer is disposed between the lower substrate and the upper substrate, and a color filter layer which transmits only predetermined wavelengths of light is also disposed between the lower substrate and the upper substrate. An upper linear polarizer is located above the upper substrate. Accordingly, the LCD provides enhanced viewing angles via the holographic diffuser. Also, the LCD realizes high brightness via the CLC diffuser and a CLC color filter layer.

Abstract: A pixel electrode employs a transparent electrode made from indium-zinc-oxide (IZO) that is capable of preventing damage and bending thereof. In a liquid crystal display device containing pixel electrodes, the transparent electrode is made from indium-zinc-oxide (IZO) having an amorphous structure so that it can be etched within a short period of time with a low concentration of etchant. Accordingly, it is possible to prevent damage and bending of the transparent electrode upon the patterning thereof.

Abstract: A liquid crystal display contains a light source, a light guide panel that directs light from the light source towards a display panel, and optical sheets containing a diffusion sheet that spreads the light from the light guide panel and at least one prism sheet that redirects light from the diffusion sheet in a direction substantially perpendicular to the display panel. The optical sheets contain a region adjacent to the light source that has a hardened part that substantially prevents heat from being transferred to a display region of the optical sheet corresponding to the display region of the display panel and minimizes the temperature difference across the display region. The hardened part is formed on at least opposing sides of the optical sheets, overlaps a non-display region of the display panel and is bent or contains a convex part that projects towards the display panel.
