  • Publication number: 20170153516
    Abstract: The present invention provides a pixel structure and a liquid crystal display panel. Areas of the red sub pixel (R) and the green sub pixel (G) are set to be equal, and an area of the blue sub pixel (B) is smaller than the area of the red sub pixel (R) or the green sub pixel (G), and an area of the white sub pixel (W) is not less than the area of the red sub pixel (R) or the green sub pixel (G). By adjusting the area ratio of the red sub pixel (R), the green sub pixel (G), the blue sub pixel (B) and the white sub pixel (W) to reduce the area of the blue sub pixel (B) and relatively enlarge the area of the white sub pixel (W), the white dot coordinate in the RGBW liquid crystal display panel can be adjusted.

  • Publication number: 20160342042
    Abstract: The present invention provides a pixel structure and a liquid crystal display panel including the pixel structure. The pixel structure includes a plurality of pixel units (1) arranged in an array. Each of the pixel units (1) includes a red sub-pixel (11), a green sub-pixel (12), and a blue sub-pixel (13) that are arranged in the form of a window sash. The red sub-pixel (11) and the blue sub-pixel (13) are arranged in a row in a vertical direction. The green sub-pixel (12) is individually arranged in a row. A surface area of the green sub-pixel (12) is greater than or equal to the sum of surface areas of the red sub-pixel (11) and the blue sub-pixel (13). A black matrix (4) is arranged along outer circumferences of the red sub-pixel (11), the green sub-pixel (12), and the blue sub-pixel (13). The pixel structure reduces the area occupied by the black matrix (4), expands the surface area of the green sub-pixel (12), increases aperture ratio and light transmittance, and enhances displaying performance.
