Embodiment 1

[0036] This embodiment provides a method for improving the alignment effect of self-aligned liquid crystals, which is suitable for liquid crystal display panels, especially for the problem of dark lines caused by liquid crystal alignment caused by self-aligned liquid crystals in the process of power-on-curing.

[0037] Specifically, the liquid crystal display panel includes an array substrate, a color filter substrate arranged parallel to and spaced from the array substrate, and a liquid crystal molecular layer sandwiched between the array substrate and the color filter substrate; The potential of the substrates is the same, which can avoid the light leakage caused by the rotation of the liquid crystal on the black photoresist, but in the process of VA curing to form the pre-tilt angle of the liquid crystal, synchronously applying power to the array substrate / color filter substrate will cause darkening caused by the fringe electric field. pattern.

Embodiment 2

[0048] This embodiment provides another method for improving the alignment effect of self-aligned liquid crystals. This method is suitable for liquid crystal display panels, especially for topographical changes caused by the middle of pixels on the array substrate, and after the array substrate / color filter substrate is powered on synchronously. The fringe electric field generated by the pixel electrodes at the array substrate and the keel is also a problem of dark lines caused by poor liquid crystal alignment.

[0049] Specifically, the liquid crystal display panel includes an array substrate, a color filter substrate arranged parallel to and spaced from the array substrate, and a liquid crystal molecule layer sandwiched between the array substrate and the color filter substrate.

[0050] For details, see Figure 10 , the array substrate includes a third substrate 11 and an electrode group disposed on the third substrate 11 and facing the liquid crystal molecule layer (not sh...

Abstract

The invention discloses a method for improving the alignment effect of self-aligned liquid crystals and applies to a liquid crystal display panel. The liquid crystal display panel comprises an array substrate, a color filter substrate arranged in parallel to the array substrate and at an interval as well as a liquid crystal molecular layer clamped between the array substrate and the color filter substrate. According to the method, the liquid crystals are solidified by only powering up a common electrode in the color filter substrate, or a common electrode in the array substrate is arranged ina non-display area of the array substrate. Compared with the uncertainty and complexity by changing the material of a self-aligned liquid crystal system, the method for improving the alignment effectof the self-aligned liquid crystals has the advantages that the problem of poor alignment of self-aligned liquid crystal display can be effectively solved on the premise that the material of the self-aligned liquid crystal system keeps unchanged, and has great significance in further application of the self-aligned liquid crystal display.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display panels, and specifically relates to a method for improving the alignment effect of self-aligned liquid crystals. Background technique [0002] At present, TFT-LCD is mainly divided into VA type and IPS type. The liquid crystal cell part of the vertical alignment type liquid crystal display is generally formed by an alignment film, a liquid crystal and a polymer monomer composition, and there are transparent electrodes opposite to each other on the inner side of the upper and lower glass substrates. The upper and lower polarizers orthogonal to each other are attached on the outer side. Among them, the alignment film makes the negative liquid crystal used in VA-type LCD form the vertical alignment of the initial state, so that it is in a normally black state when no voltage is applied; after that, the liquid crystal has a certain pre-tilt angle by applying voltage and ultraviolet ligh...
