  • Patent number: 12555550
    Abstract: The present application discloses a liquid crystal display panel and a display terminal, a light transmittance of a primary area color filter block of the liquid crystal display panel is less than a light transmittance of a secondary area color filter block; when a gray level value of an image data is less than a preset value, the primary area pixel electrode is driven to display, and when the gray level value of the image data is greater than the preset value, the primary area pixel electrode and the secondary area pixel electrode are driven to display, so that the overall gray level color gamut is increased without losing the light transmittance, and the color deviation at the large viewing angle is improved.
