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...
