Abstract

The invention provides a display device and a display, and relates to the technical field of display. By the display device and the display, the problem of reflection caused by external environment light in an OLED layer is solved, and the technical problem of low light transmittance emitted from the OLED layer is solved. A controllable flexible display device comprises the OLED layer, a one fourth wave plate, a first conductive substrate layer, a controllable liquid crystal layer and a second conductive substrate layer which are arranged in a lamination way, wherein the controllable liquid crystal layer comprises liquid crystal molecules and a dichroic dye; when environmental light intensity is larger than a preset threshold, the liquid crystal molecules and the dichroic dye in the controllable liquid crystal layer are controlled to be orientated according to a first direction, so that environmental light reflected by the OLED layer is absorbed by the dichroic dye; and when the environmental light intensity is not larger than the preset threshold, the liquid crystal molecules and the dichroic dye in the controllable liquid crystal layer are controlled to be orientated according toa second direction, so that light sent out from the OLED layer completely passes through the controllable liquid crystal layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a display. Background technique [0002] Since the electrode layer (located in the OLED layer) in an OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display is generally made of metal, it has a relatively high reflectivity. When the OLED display is used outdoors with strong external ambient light, the high reflection of the electrode layer to the ambient light will lead to poor readability of the display. Contents of the invention [0003] In view of the above defects, the present invention provides a display device and a display, which are used to solve the technical problem of reflection caused by ambient light on the electrode layer and low transmittance of light emitted by the electrode layer. [0004] In a first aspect, the present invention provides a display device, comprising: a stacked OLED layer, a 1 / 4 wave plate, a first condu...
