    摘要: In a transflective liquid crystal display having a transmission area and the reflection area, the transmissive electrode is connected to a switching element to control the liquid crystal layer in the transmission area, and the reflective electrode is connected to the switching element via a separate capacitor to control the liquid crystal layer in the reflection area. The separate capacitor is used to shift the reflectance in the reflection area toward a higher voltage end in order to avoid the reflectance inversion problem. In addition, an adjustment capacitor is connected between the reflective electrode and a different common line. The adjustment capacitor is used to reduce or eliminate the discrepancy between the gamma curve associated with the transmittance and the gamma curve associated with the reflectance.

    摘要: A transflective liquid crystal display having a plurality of pixels, each pixel having a plurality of color sub-pixels, each sub-pixel having a transmission area associated with a first charge storage capacitance and a reflection area associated with a second storage capacitance. In the sub-pixel, a data line, a first gate line, a second gate line and a common line are used to control the operational voltage on the liquid crystal layer associated with the sub-pixel. The first and second gate lines are separately set at a first state and a second state. The ratio of the first charge storage capacitance to the second charge storage capacitance can be controlled according to the states of the gate lines. The second charge storage capacitance is provided by two capacitors connected in parallel through a switching element which can be open or closed according to the states of the gate lines.

    摘要: The invention provides an LCD panel with main slits corresponding to alignment protrusions. The gate lines are shielded by the electrode portion and do not overlap the main slits. Because the gate line and the major slits do not overlap, the liquid crystal molecule arrangement of the liquid crystal layer is not affected by the operating voltage of the gate line.

    摘要: An LCD panel includes a first substrate, a second substrate, alignment protrusions and a liquid crystal layer between the first substrate and the second substrate. The first substrate includes pixel units arranged in an array. Each of the pixel units has at least one reflection area and one transmittance area. The first substrate has concaves in the reflection areas. The second substrate is above the first substrate. The first substrate or the second substrate has at least one padding layer in the reflection area. The alignment protrusions having approximately the same height are disposed on the second substrate and located in centers of each of the reflections and the transmittance areas. In the reflection area, a group of the alignment protrusions are in the concaves to keep a gap from the first substrate. The other group of the alignment protrusions outside of the concaves contact with the first substrate directly.
