Realize best way of the present invention

At first, Figure 1A-1C and the Fig. 2 with reference to accompanying drawing elaborates to one embodiment of the present of invention.The detailed structure of the banded display element 1 of the present invention has been shown among Figure 1A-1C.The structure of a kind of display 10 that is made of conductive strips 2 and display element of the present invention 1 has been shown among Fig. 2.

Among the figure, banded display element 1 is the flat band of sandwich construction, and by the backside conductive layer 4 at the nesa coating 5 in front and the back side luminous or colour development material layer 3 being clipped in the middle constitutes.Whole display element profile is the strip of strip.Wherein, the backside conductive layer 4 that contacts with conductive strips (electrode) is discontinuous structure, be penetrated with the extremely narrow transverse slot of width 6 with the spacing that equates basically on it, thereby become the boxed area structure of the mutual insulating of arranging along the length direction of display element, so that insulated from each other between each boxed area of adjacent backside conductive layer 4.The conductive strips that label 2 constitutes for conductive material, conductive strips are the conductor strip of strip.

Display among Fig. 2 is the tiling arrangement architecture.When display material is harder, when the banded display element of making is difficult for braiding, adopt this structure more easily to realize.Parallel to each other and with the display element 1 of essentially identical spacing configuration with its backside conductive layer be parallel to each other and equally with the contacted mode crossing at right angle of conductive strips of essentially identical spacing configuration, constitute array of display thus, each point of crossing all is a display unit (or claiming pixel).Driving circuit connects strip display element and conductive strips respectively.When nesa coating ground connection, when backside conductive layer connect driving voltage, the transverse slot 6 of backside conductive layer had guaranteed to show in the zone that only occurs in the backside conductive layer energising.The transparency conducting layer of display element and conductive strips are the site selection electrodes in length and breadth of array of display (pixel), and through electroluminescent film or electrochomeric films 3, backside conductive layer 4 flow to conductive strips to electric current by transparency conducting layer 5.

Conductive strips are with adopting bonding between the banded display element backside conductive layer or welding maintenance contact (conducting) between the two.

Display element 1 can adopt electroluminescence (EL) element or electrochromism (ECD) element.Adopt evaporation or coating to make two

conductive layers

4 and 5 respectively on the two sides of electroluminescent material or electrochromic material film, wherein conductive layer 5 is a transparency conducting layer.Apply voltage or electric current by these two conductive layers to the display material film, then have visible light to send (electroluminescence) or catoptrical colour brightness changes (electrochromism) in transparency conducting layer 5 one sides, realization information thus shows.

Fig. 3 A is the structural representation of another embodiment of the present invention, and this structure has been used a kind of braiding structure, and this weaving manner makes display element be staggered.This braiding structure can adopt banded weaving, and evaporation or coating only need to carry out on narrow strip material, and can process continuously.Because the inherent characteristic of weaving can make braiding carry out continuously.Thereby, can reach the purpose of producing large screen display by the display element of producing the long width of cloth.

For realizing this braiding structure, present embodiment has used the structure of the conductive strips shown in Fig. 3 B.Conductive strips 2 are made of two-layer structure, and one side is conducted electricity the another side insulation, and 7 among the figure is conducting surface, and 8 is insulating surfaces.To make the conducting surface 7 of conductive strips 2 contact (conducting) formation display unit with the backside conductive layer of display element 1 during braiding, the insulating surfaces 8 of conductive strips 2 is contacted with the nesa coating of display element 1.Density when guaranteeing width that control element is wanted in insulation between the banded display element and the insulation between the conductive strips and thickness and braiding.

Fig. 4 is the another kind of implementation of braiding structure.Among this embodiment, display is made up of display element, conductive strips and insulated wire.Wherein 9 is insulated wire, and insulated wire is the insulator strip of strip.Warp-wise is spaced strip display element and insulated wire, and broadwise is spaced conductive strips and insulated wire.Conductive strips are with forming Ohmic contact between the strip display element backside conductive layer, insulation between the spaced insulated wire assurance conductive strips and the insulation between the strip display element.

On the basis of tiling structure display shown in Figure 2, with insulated wire 9 display element and conductive strips are combined by braiding, as shown in Figure 4.Width ratio between adjustment conductive strips, strip display element and the insulated wire three can be adjusted the utilization ratio of strip display element.When the electromagnetic field effects of display element around being subjected to, the insulated wire that is surrounded by lead in the middle of utilizing be woven in display element around form shielding, the influence of control electromagnetic field.

Display of the present invention can adopt multiple display element, as electroluminescent cell and electric driven color-changing part.Because the ribbon element of display element, so when having suitable narrow spectrum display element, can not realize colored demonstration by add the colour filter film at banded display element with white luminous spectrum for separating.

All the above embodiments are to explanation of the present invention, rather than limit it.Those skilled in the art can change and revise it.
