The display device provided by the application comprises a backlight source, a first driving electrode, a polymer dispersed liquid crystal (PDLC) light modulating layer, a second driving electrode and a photochromic layer, wherein the first driving electrode is arranged on the backlight source; the PDLC light modulating layer is arranged on the first driving electrode; the second driving electrode is arranged on the PDLC light modulating layer; the photochromic layer is arranged on the second driving electrode.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and system. Background technique [0002] At present, the drawing and writing board mainly uses ultra-thin magnetic microcapsule main board as the writing surface layer. According to the principle of magnetic material movement, it is equipped with a special magnetic writing pen and eraser. There is also a type of product that uses pressure-sensitive cholesteric liquid crystals to make black and white drawing and writing boards. , but this type of drawing and writing tablet cannot realize the display of fine patterns. [0003] Compared with the magnetic electronic paper and pressure-sensitive liquid crystal electronic paper currently on the market, or the writing board that uses a touch screen combined with electronic paper, in terms of product effect, the present invention can realize the direct input and display of fine patterns, and can display color...
