Abstract: The present invention provides an in-plane switching liquid crystal display (IPS-LCD) device that includes a substrate, a protrusive layer having many protrusions on the substrate and a transparent electrode on each of the protrusions.

Abstract: A light guide plate (2) includes a light output surface (20) and a bottom surface (22) opposite to the light output surface. The bottom surface defines a plurality of V-shaped grooves (221) thereat, and each of the V-shaped grooves is bounded by a pair of walls along a length thereof. The walls cooperatively form an apex angle, and each of the V-shaped grooves has an apex angle in a range of 67° to 85°.

Such directions are typically directions toward a viewer of an associated liquid crystal display panel. Accordingly, a backlight module that employs the light guide plate may advantageously obtain more efficient utilization of illumination and greater brightness in particular desired directions.

A baffle-wall (150) is disposed inside the sealant at a peripheral portion of the second substrate. The baffle-wall, the sealant and the first and second substrates cooperatively define at least one retaining space (160) therebetween. The baffle-wall and the first substrate cooperatively define at least one channel (170) therebetween, the channel communicating between the liquid crystal layer and the retaining space. During manufacturing, the baffle-wall helps prevent air bubbles from returning to the liquid crystal layer. Thus the liquid crystal panel has a high display quality.

Thus the prism sheet can be omitted from the liquid crystal display device. The number of optical elements is reduced, and the liquid crystal display device has a lower cost and less weight.

Abstract: A driving method for an active matrix liquid crystal display panel includes the following steps. First, a frame period is divided into a display period (t1) and a black insertion period (tr). A gray-scale voltage is generated according to a desired corresponding light transmittance of each pixel of the liquid crystal display panel; and during the display period, the gray-scale voltage is supplied to a corresponding pixel electrode of the liquid crystal display panel. Then during the black insertion period, a restoring voltage Vh is supplied to the pixel electrode, so that the pixel is returned to an initial black state. Accordingly, the quality of motion pictures of the liquid crystal display panel is good.

Abstract: A color filter and a method for manufacturing the same are provided. The color filter includes a polarizer matrix (202), which is patterned in accordance with the pixel arrangement of a liquid crystal display device. The polarizer matrix (202) is made of a thin crystal film material, which may linearly polarize incident light along one direction. By incorporating with a polarizer film (206), the polarizer matrix (202) becomes an effective black matrix. A thinner black matrix may thus be produced, and the manufacturing processes of the color filter are simplified.
