Abstract

The invention discloses a flexible matrix inorganic electroluminescent flat-panel display, which comprises a transverse transparent conductive stripe layer (2) produced on a transparent flexible plastic base layer (1), a luminous layer (3) made of inorganic electroluminescent materials, a medium layer (4) made of insulating materials, a longitudinal back electrode stripe layer (6) made of conductive materials and arranged on the surface of the medium layer, a protective cover layer (7) and a plastic film (9) arranged at the outermost layer and used for completely sealing; and a back electrode (5) and a transparent electrode (13) of the display are respectively connected with a matrix scanning circuit device. The flexible matrix inorganic electroluminescent flat-panel display is controlled by electronic chips and driven to give out lights by an electric field and can form dynamic images consisting of independent luminous picture elements; therefore, the flexible matrix inorganic electroluminescent flat-panel display can be applied to the fields such as dynamic advertising, luminous clothing, computer terminal and big screen image displays, and the like.

Description

technical field [0001] The invention belongs to the technical field of flat panel electroluminescence display devices application. Background technique [0002] As a terminal device of information technology, flat panel light-emitting display devices have been widely used in mobile phones, televisions, computers, and the like. At this stage, the new flat panel display technology is constantly pursuing technical indicators such as large, light, thin, and power-saving. At present, most flat panel displays are based on glass substrates, such as field emission displays (FED), liquid crystal displays (LCD), organic electroluminescent displays (OEL or OLED), and plasma displays (PDP). The disadvantages are that the glass is easily broken, the area is limited, the weight is large, the work generates heat, it cannot be bent, the production cycle is long, and the cost is high. Existing electroluminescent displays are also based on glass, such as: inorganic thick-film electrolumines...
