Thin film transistor liquid crystal display panel and liquid crystal displayer

Abstract

An embodiment of the invention discloses a thin film transistor liquid crystal display panel, which comprises multiple scanning lines, multiple data lines, and multiple pixel units; multiple scanninglines are extended along the first direction, and multiple data lines are extended along the second direction which is perpendicular to the first direction; every pixel unit comprises a red sub-pixel,a green sub-pixel, a blue sub-pixel and a white sub-pixel; the sub-pixel is electrically connected with the scanning line and the data line, and every sub-pixel comprises a main pixel electrode and asecondary pixel electrode; when the data line inputs the same data signal to the sub-pixel, the pressure difference between the main pixel electrode and the secondary pixel electrode in the red sub-pixel, the blued sub-pixel and the green sub-pixel is more than the pressure difference between the main pixel electrode and the secondary pixel electrode in the white sub-pixel. The embodiment of theinvention further provides a liquid crystal displayer. By adopting the invention, the color cast of the thin film transistor liquid crystal display panel when it has a great visual angle can be improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a thin film transistor liquid crystal display panel and a liquid crystal display. Background technique [0002] In the field of thin-film transistor liquid crystal display, thin-film transistor liquid crystal display panels generally include red sub-pixels (R), green sub-pixels (G) and blue sub-pixels (B). The transmittance of such RGB display panels is relatively low. The prior art proposes to add white sub-pixels, that is, the thin film transistor liquid crystal display panel includes red sub-pixels (R), green sub-pixels (G), blue sub-pixels (B) and white sub-pixels ( W). However, after adding white sub-pixels, it tends to aggravate the large viewing angle of the thin film transistor liquid crystal display panel. Please refer to figure 1 ( figure 1 The middle gamma value r=2.2, observe at a viewing angle of 60°), from figure 1 As can be seen in the large viewing angle ( fi...
