Problems solved by technology

In the existing display technology, IPS mode and FFS mode have advantages in display quality such as wide viewing angle and high contrast compared with TN. However, the transparent area of ​​the transparent display displayed in IPS mode or FFS mode is displayed in normally black mode, and only Only by applying a voltage to the transparent area of ​​the above-mentioned transparent display can the transparent state of the transparent area be maintained, so the power consumption of the above-mentioned transparent display is large, and the application range is limited

Abstract

The invention discloses a transparent display. The transparent display comprises a lower polarizing plate, a first substrate, a first orientation film, a liquid crystal layer, a second orientation film, a second substrate and an upper polarizing plate which are sequentially laminated along an image display direction. The transparent display comprises multiple transparent zones and multiple display zones which are alternately arranged, a polarizing axis of the lower polarizing plate extends along a first direction, a polarizing axis of the upper polarizing plate extends along a second direction perpendicular to the first direction, the liquid crystal layer comprises a first liquid crystal layer arranged on the surface of the first orientation film and a second liquid crystal layer arranged on the surface of the second orientation film, initial directions of long axes of the first liquid crystal layer and the second liquid crystal layer in the display zones are respectively consistent with the first direction or the second direction, and initial directions of long axes of the first liquid crystal layer and / or the second liquid crystal layer in the transparent zones deviate from the first direction and the second direction. The transparent display has low energy consumption.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent display. Background technique [0002] A transparent display means that the display itself has a certain degree of light penetration, allowing users to clearly see the background behind the display while watching the display screen. Therefore, the transparent display is suitable for application in building windows, automobile windows, shop windows, and the like. [0003] The transparent display is divided into a transparent area (which can transmit external light) and a display area (RGB pixel area). At the same time, the commonly used display modes are TN (Twisted Nematic, twisted nematic), IPS (InPlaneswitching, plane twist), FFS (FringeFieldSwitching, fringe field switch), multi-chip VA (Vertical alignment) mode. In most usage scenarios, it is required that the transparent display is in a transparent state without displaying most of the time, and only when peo...
