    摘要: A display panel has a high pixel and a low pixel that are formed in a pixel area. A driving section receives a first image signal from an external device, outputs a second image signal to the high pixel using gamma data that corresponds to a high pixel gamma curve, and outputs a third image signal to the low pixel using gamma data that corresponds to a Sow pixel gamma curve. A driving section outputs the third image signal to the low pixel using the same gamma data for RGB data that correspond to a low gradation of the low pixel gamma curve.

    摘要: Provided are a liquid crystal composition and a liquid crystal display (LCD) including the liquid crystal composition. The LCD includes a first display panel a second display panel facing the first display panel, and a liquid crystal composition disposed between the first display panel and the second display panel. If a dielectric constant in a direction parallel to a long axis of liquid crystals is defined as a horizontal dielectric constant ∈∥, a dielectric constant in a direction perpendicular to the long axis of the liquid crystals is defined as a vertical dielectric constant ∈⊥, and the difference between the vertical dielectric constant ∈⊥ and the horizontal dielectric constant ∈∥ is defined as dielectric anisotropy Δ∈, then a ratio Δ∈/∈⊥ of the dielectric anisotropy Δ∈ to the vertical dielectric constant ∈⊥ of the liquid crystal composition is 0.5 or less.

    摘要: A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n−1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n−1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.

    摘要: A liquid crystal display includes first and second opposing spaced insulating substrates, pixel electrodes formed on the first substrate, a common electrode formed on at least one of the first and second substrates, and a liquid crystal layer interposed there between the first substrate and the second substrate. In this structure, each pixel electrode is divided into a main-pixel electrode and a sub-pixel electrode, to which different signal voltages are individually applied at the same gray scale. Further, a signal voltage to be applied to the sub-pixel electrodes is determined by a gamma value satisfying the following equation: Gamma K=(current gray scale/maximum gray scale)f F(Gray Scale)=α×(maximum gray scale/current gray scale), wherein α is a constant.
