Description
Technical field
The utility model relates to Electronic Paper (E-Paper) field of display, relates in particular to a segment type electric paper display that adopts glass substrate.
Background technology
Electronic Paper (E-Paper) is a kind of display material that can realize the equally comfortable reading of sensitive paper, has distinguishing features such as frivolous, flexible.And being exactly a kind of employing Electronic Paper, electric paper display realizes the information device shown; It adopts modern electronic technology; Make people when reading information, have tradition to read the visual perception of papery literal again, do not make problems such as people's eyes tire easily and do not have traditional monitor, and its show state has bistability; Can realize low energy consumption effectively; After power supply was closed, pattern or the numeral selecting to show still can reach the purpose of energy-saving and emission-reduction keeping more than one month on the display effectively.
General passive type electric paper display all adopts printed circuit board (PCB) or flexible circuit board as substrate, and this design is because of holing on circuit board to reach the requirement of wiring, and line width is bigger, and the precision of wiring and display message amount receive very big restriction; And because of Electronic Paper is very high to humidity requirement, and circuit board wiring needs on substrate, to hole, and has influenced the humidity resistance of product, greatly reduces reliability of products.
Summary of the invention
The purpose of the utility model provides a glass substrate segment type electric paper display; It takes to stride layer interconnection technique can realize high precision int, densification; And existing moisture resistance problem when solving printed circuit board (PCB) fully and making substrate, improved reliability of products can, simultaneously; Simplify board structure, reduced cost.
To achieve these goals, the technical scheme of the utility model employing is:
On glass substrate, form the transparent line layer of tin indium oxide (ITO) through exposure, etch process; On the transparent line layer of tin indium oxide (ITO), be coated with insulating film layer; Pixel and background electrode layer are arranged on insulating film layer; The display pixel electrode block separates with the background electrode block fully, and its pixel is a segment type structure, and the E-paper thin film that surface band tin indium oxide (ITO) film is arranged on pixel and background electrode layer is as its public electrode; And be connected with the firing point of pixel and background electrode layer one side; Wherein, on vertical interface, the relevant position that need conduct between the transparent line layer of said tin indium oxide (ITO) and pixel and the background electrode layer is connected through striding layer.
The relevant position that need conduct between the transparent line layer of described ITO and pixel and the background electrode layer can be striden a layer tie point through setting and is connected, and strides layer tie point and realizes in predetermined space can be through the silk-screen insulation course time.
When needs show; The predetermined level signal that is produced by driving circuit is sent to through ITO terminal Ts and ITO line layer strides a layer tie point; Be sent to the corresponding display pattern of pixel and background electrode layer by striding layer tie point again; Thereby realized layer conducting of striding from the ITO line layer to the display pattern layer, the predetermined voltage that is produced by driving circuit simultaneously is sent to public electrode ito thin film layer through ITO terminal Tc firing point, like this; On the Electronic Paper of corresponding display pattern, just formed an electric field, thereby the arrangement that changes the charged capsule in the Electronic Paper realizes showing.
What the utility model adopted strides layer conducting interconnection technique compared with prior art, has simpler board structure, and more simple manufacturing process has bigger display message amount, and higher unfailing performance has reduced cost simultaneously again.
