    Abstract: The present invention provides a polymer stabilization alignment liquid crystal display panel having a plurality of pixel regions. Each pixel region includes a main region and a sub region, and a first pixel electrode and a second pixel electrode correspond to the main region and the sub region respectively. Each first pixel electrode is separated from the adjacent data line and thereby forming a gap therebetween. Each second pixel electrode partially overlaps the adjacent data line. In addition, each second pixel electrode includes a plurality of branches, and at least one edge of the branches may be parallel to the data lines. Accordingly, the present invention not only can increase the aperture ratio, but also well control the liquid crystal molecules located near the data lines. Therefore, the display quality of the liquid crystal display panel can be improved.

    Abstract: A liquid crystal display (LCD) device and an LCD panel are disclosed. The LCD panel comprises charging scanning lines, discharging scanning lines, first data lines, second data lines and pixel units. The charging scanning lines and the discharging scanning lines are arranged alternately and parallel with each other in a first direction. The first data lines and the second data lines are arranged parallel with each other in a second direction and insulatedly intersect the charging scanning lines and the discharging scanning lines. Each pixel unit comprises a charging TFT, a discharging TFT and a pixel electrode. When two adjacent charging scanning lines are being scanned in the LCD panel, two adjacent discharging scanning lines located in other rows different from those of the two adjacent charging scanning lines being scanned are scanned within a same scanning time frame.

  • Publication number: 20130107172
    Abstract: A multi-domain vertical alignment liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, and at least one projection. The second substrate is opposite to the first substrate. The liquid crystal layer is interposed between the first and second substrates. The projection is formed in the first substrate. In displaying a dark state, a lower surface of the projection is on the same plane as a lower surface of the first substrate; and in displaying a bright state, the projection bulges outward to have the lower surface of the projection projecting outward beyond the lower surface of the first substrate. When the multi-domain vertical alignment liquid crystal display panel displays a dark state, the projection does not undergo deformation so that the projection does not affect the directions of the liquid crystal molecules contained in the liquid crystal layer thereby eliminating occurrence of light leakage.

  • Patent number: 8349275
    Abstract: A microfluidic device with microstructure includes a channel for accommodating an electrolytic solution therein and at least one microstructure formed in the channel. When an alternating-current signal is input to the microfluidic device so that a surface of the microstructure is polarized by a generated electric field, ions having polarity reverse to that of an electrolytic solution will migrate to the surface of the microstructure to form a field-induced electrical double layer to result in electro-osmotic flows at the corners at two sides of the microstructure, which causes formation of relatively fierce circular vortices in the solution. A sensing system and a sensing method using the microfluidic device with microstructure are also disclosed.
