A vertical alignment mode reflective-transmissive liquid crystal display (LCD) includes the first substrate having an upper surface and a lower surface and the second substrate having an upper surface and a lower surface and facing the first substrate. A cell is formed between the upper surface of the first substrate and the lower surface of the second substrate. The cell has a plurality cell-gaps. A vertically aligned liquid crystal layer is disposed in the cell. The reflective region of the LCD has a cell-gap ranging from about 1.8 μm to about 2.2 μm, and the transmissive region of the LCD has a cell-gap ranging from about 3.6 μm to about 4.0 μm. The first optical film assembly including the first polarizer is disposed on the lower surface of the first substrate. The second optical film assembly including the second polarizer is disposed on the upper surface of the second substrate. An absorption axis of the first polarizer is substantially perpendicular to that of the second polarizer.
Abstract:
The present invention discloses an address buffer and a semiconductor memory device having the address buffer. The address buffer comprises a first buffer for latching a signal in response to a first control signal in a normal operation mode in the semiconductor memory device and generating a buffered signal by buffering the latched signal in response to a second control signal, and a second buffer for maintaining a mode-setting signal in a reset status in the normal operation mode and for outputting the mode-setting signal by using the latched signal in response to the first control signal and a mode-setting command in a mode-setting operation mode. Accordingly, the mode-setting signal is generated only in the mode-setting operation mode, thereby reducing undesirable current consumption.
Abstract:
A method and a system for cooling a steel strip are disclosed. A high water volume mist cooler and a low water volume mist cooler are disposed along a direction in which the steel strip travels. The high water volume mist cooler sprays high water volume mists onto the surfaces of the steel strip to cool the steel strip, and then the low water volume mist cooler sprays low water volume mists onto the surfaces of the steel strip to cool the steel strip, thereby cooling the steel strip while suppressing the influence of transition boiling, to prevent the steel strip from having a temperature-nonuniform portion.

A liquid crystal display includes a first substrate and a second substrate facing the first substrate, a gate line and a data line disposed on the first substrate, and a pixel electrode disposed on the first substrate. The pixel electrode is connected to the gate line and the data line, and includes subregions. The liquid crystal display further includes a storage electrode disposed on the first substrate overlapping the pixel electrode to form a storage capacitor, a common electrode disposed on the second substrate, and a liquid crystal layer interposed between the pixel electrode and the common electrode and including liquid crystal molecules disposed therein. The pixel electrode includes a stem defining boundaries between the subregions, and a width of the stem changes from a center portion of the pixel electrode to a peripheral portion of the pixel electrode.

A rivet aperture is formed in each of the coupling protrusions. Straps are disposed such that each strap passes over both the corresponding rivet aperture of the disc plate and the corresponding rivet aperture of the hat part. The rivets are inserted into the corresponding straps and the corresponding rivet apertures to fix the straps, the disc plate and the hat part together.
Abstract:
A device for optimizing a data compression level when processing a Hybrid Automatic Repeat reQuest (HARQ) signal includes a combiner which receives a log likelihood ratio (LLR) signal, determines whether the LLR signal is a new or retransmitted signal, and generates a composite signal by combining the LLR signal with a related signal received and previously stored when the LLR signal is the retransmitted signal; a compression level decision unit which calculates a first compression level based on quality of a received signal, calculates a second compression level based on an available memory size, and decides a final compression level according to the first compression level and the second compression level; a compressor which compresses the LLR signal according to the final compression level; a HARQ memory which stores the compressed signal; and a decompressor which decompresses a signal read from the HARQ memory.
