Abstract

The invention discloses a display panel with switchable transmission and mirror plane. The display panel comprises a first substrate, a liquid crystal layer and a second substrate which are arranged from top to bottom, wherein multiple pixel units are formed in the second substrate, a first polarizing film and a first quarter wave plate are arranged on the first substrate, and the included angle between a fast-slow axis of the first quarter wave plate and a light transmitting axis of the first polarizing film is 45 degrees; a second polarizing film and a second quarter wave plate are arrangedon the second substrate, and the included angle between a fast-slow axis of the second quarter wave plate and a light transmitting axis of the second polarizing film is 45 degrees; each pixel unit comprises a transmission area and a reflection area, reflection electrodes are arranged on the second substrate, and an auxiliary electrode is arranged on one side of each of the first substrate and thesecond substrate; when voltage is applied to the reflection electrodes and the auxiliary electrodes, the reflection area is opened, at the moment, pixel electrodes do not apply voltage, and the transmission areas are closed; and when voltage is not applied to the reflection electrodes and the auxiliary electrodes, the reflection areas are closed, at the moment, the pixel electrodes and public electrodes apply voltage, and the transmission areas are opened. The invention also discloses a vehicle rearview mirror.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel with switchable transmission and mirror surfaces and a vehicle rearview mirror. Background technique [0002] The complexity and information density of the automotive information system are increasing day by day, which makes the display inside the car no longer just focus on the instrument display, but to meet the display needs of more and more detailed and diverse in-vehicle information. [0003] As the price of liquid crystals continues to decrease, the specifications of automotive displays are slowly surpassing the previous large display panels, and their development speed begins to accelerate. The external functionalization of advanced driver assistance systems (ADAS), the promotion of rear view display systems using rear cameras in the United States, and the relaxation of regulations for cameras in side and rear-view mirrors all require vehicle...
