Display panel and display device

Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate and the second substrate are arranged oppositely, the liquid crystal layer is located between the first substrate and the second substrate, and the display panel further comprises a magnetic structure. The magnetic structure is additionally arranged in the display panel, so that a magnetic field is generated through the magnetic structure; liquid crystal molecules in the display panel deflect under the action of the magnetic field and can maintain a preset deflection state accordingly, therefore user experience can be improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] Due to its low power consumption, relatively low manufacturing cost and no radiation, liquid crystal displays have become the mainstream of flat panel displays and are widely used in various display components, such as displays on electronic devices such as mobile phones, computers, and televisions. [0003] The main structure of the liquid crystal display includes the array substrate formed by the box, the color filter substrate and the liquid crystal layer between the array substrate and the color filter substrate. The display principle is to apply an electrical signal to the liquid crystal panel to control the rotation of the liquid crystal in the liquid crystal layer , so as to realize image display, in order to obtain uniform brightness and high contrast, the liquid crystal molecules in the liquid crystal panel m...

Problems solved by technology

However, for some types of liquid crystal displays, the alignment layer alone cannot achieve a good alignment effect. For example, for photo-alignment liquid crystal displays, the anchoring ability of the photo-alignment layer is weak, which is prone to afterimages, which affects the display. effect, and for OCB (optically compensated Birefringence: Optically Compensated Birefringence) liquid crystal display, see figure 1 , the initial state of the liquid crystal molecules is only in the spray alignment state under the action of the alignment layer. In order to display in the liquid crystal cell with this structure, it needs a certain warm-up time to convert the liquid crystal in the spray alignment state into the liquid crystal in the bend alignment state. For this reason, it is necessary to install a drive circuit inside the liquid crystal unit. When the OCB liquid crystal display is turned on, the drive circuit applies a deflection electric field E1 to convert the liquid crystal from the spray alignment state to the bend alignment state. After a certain warm-up time, the liquid crystal display can enter In the normal working state, then gradually increase the electric field to E2, and the LCD enters the dark state. Obviously, the above warm-up process caused the slow start of the OCB LCD, resulting in poor user experience
