本发明的液晶显示面板的驱动方法及液晶显示面板，通过将液晶显示面板中同一列的每个像素的蓝色子像素放置在红色子像素以及绿色子像素之间，搭配特定的扫描顺序，将发生电容耦合对应的子像素设置成人眼敏感度较低的蓝色子像素，从而改善液晶显示面板的显示品质，并且液晶显示面板驱动时，每扫描三行子像素切换一次亮度，降低了子像素的充放电频率。The driving method of the liquid crystal display panel of the present invention and the liquid crystal display panel, by placing blue sub-pixels of each pixel of the same column in the liquid crystal display panel between the red sub-pixel and the green sub-pixel, with a specific scanning order, The sub-pixel corresponding to the capacitive coupling is configured to set a blue sub-pixel with low sensitivity of the adult eye, thereby improving the display quality of the liquid crystal display panel, and when the liquid crystal display panel is driven, the luminance is switched every three rows of sub-pixels, and the sub-pixel is lowered. Charge and discharge frequency.
综上，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。In the above, the present invention has been disclosed in the above preferred embodiments, but the preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the claims.
