Problems solved by technology

In the process of solidifying the liquid crystal to form a pre-tilt angle, the signal coupling between the pixel electrode and the common electrode on the first substrate is likely to cause the tilt of the liquid crystal molecules to be affected by the common electrode, and dark lines are generated on the edge of the pixel, which makes the display panel wear Reduced transmittance

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a liquid crystal solidification method, a display panel and a display device, wherein the liquid crystal solidification method is used for a display panel, the display panel comprises a first substrate, a second substrate and a liquid crystal, the first substrate comprises a pixel electrode and a common electrode, and the pixel electrode At least partially overlapping with the common electrode to form a storage capacitor, the second substrate and the first substrate are arranged oppositely, and the liquid crystal is arranged between the first substrate and the second substrate; the liquid crystal curing method includes the following steps: applying a curing voltage signal to the pixel electrode, To control the liquid crystal to tilt according to the preset angle; when the liquid crystal tilts according to the preset angle to reach a stable state, irradiate the liquid crystal with ultraviolet light to cure; wherein, the effective value of the curing voltage signal is 7-10V. The technical scheme of the invention avoids the generation of dark lines at the edges of pixels, and improves the transmittance of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal curing method, a display panel and a display device. Background technique [0002] Currently, liquid crystal display panels on the mainstream market can be divided into three types, namely twisted nematic (Twisted Nematic, TN) or super twisted nematic, in-plane switching (In-Plane Switching, IPS) and vertical alignment (Vertic Alignment). , VA) type. A liquid crystal display device generally includes a backlight module, a first substrate and a second substrate oppositely arranged, and liquid crystal filled between the first substrate and the second substrate. In the process of solidifying the liquid crystal to form a pre-tilt angle, the signal coupling between the pixel electrode and the common electrode on the first substrate will easily lead to the tilt of the liquid crystal molecules being affected by the common electrode. The transmittance is reduced. Co...
