Embodiment Construction
[0030] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.
[0031] The present invention is aimed at the existing liquid crystal display panel. In a specific scanning mode, due to the coupling effect of the storage capacitance of the sub-pixels in some rows, the voltage of the sub-pixels in some rows is pulled down, thereby causing the abnormality of screen flicker or image afterimage Display problem, the embodiment of the pres...

A liquid crystal display panel, comprising high-level scanning driven first subpixel rows and low-level scanning driven second subpixel rows. The first subpixel rows and the second subpixel rows are arranged in staggered fashion; the scanning sequence of scanning lines is the (3n+2)th row, the (3n+1)th row and the (3n+3)th row; n is an integer progressively increasing from 0; the capacitance values of storage capacitors (311, 411) corresponding to the scanning lines in the (3n+2)th row are smaller than the capacitance values of storage capacitors (308, 408) corresponding to other scanning lines. By reducing the capacitance values of the storage capacitors (311, 411) corresponding to an abnormal display row, the degree to which the voltage is pulled down is reduced and image flickering or afterimage is avoided.
Description
technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel and a liquid crystal display device having the liquid crystal display panel. Background technique [0002] Existing liquid crystal display panels often use a three-dimensional transistor (Tri-gate) structure in order to reduce costs, such as figure 1 As shown, it is an existing liquid crystal display panel, including a plurality of sub-pixels arranged in an array, and the sub-pixels include red sub-pixels R, green sub-pixels G, and blue sub-pixels B, and the blue sub-pixels in each row of sub-pixels B. Green sub-pixels G and red sub-pixels R are arranged alternately and repeatedly in sequence. When this structure is driven, the second row of sub-pixels, the first row of sub-pixels, the third row of sub-pixels, the fifth row of sub-pixels, and the fourth row of sub-pixels are used. Sub-pixels, sub-pixels in row 6, sub-pixels in row 8...
