Description of the invention (1) The present invention relates to the improvement of the electroluminescent signal lamp, the method of manufacturing the improved electric signal lamp, and the method and device for operating the improved electric signal lamp. More specifically, the present invention relates to improvements in electroluminescence lamps, in which the electroluminescence (EL) lamp is operated as a multi-element (or multi-lamp) display 'to provide daylighting' or used in EL display lighting or button lighting applications need to generate specific dynamic sequences. The invention also relates to static el displays. Electroluminescence (EL) lamps are well known. An EL lamp is like a capacitor in which a dielectric is sandwiched between electrodes, and at least one electrode of the capacitor is transparent. When an AC electric field is applied to a capacitor, protons (ie, fluorescent substances) with electroluminescence properties stop in the dielectric to emit light. One of the problems with previous EL display technology is the design of multi-lamp el displays. This type of display has multiple El lamps on a single flat panel. As a result, it becomes quite difficult to provide attachment, conduction paths, and power to the various components of the display and to provide the required physical flexibility. The conventional method for manufacturing signal lamps and multi-lamp displays has never reached the ideal state. The key is that it is difficult to form adhesion to adjacent substrates when laying conductive paths on insulating UV dielectric materials. In addition, the configuration of the electrodes (that is, the configuration of the light-emitting EL lamp) is covered on the conduction path, and the number depends on the 2-dimensional layout of the EL display. The required shape of the EL lamp is determined by the two-dimensional shape (image) of the electrodes located behind the EL display and the luminescent substance. Generally, the electrode is formed by coating a silver conductive layer on a combination of a luminescent substance and a dielectric layer. A traditional method of laying a conductive path on the conductive area of an EL display is to apply the Chinese national standard (CNS) A4 specification (2JOX 297 public meals) I ---— Μ -------- ^ i! --- Μ.

Fig. 1 is a cross-sectional view of a conventional two-element electroluminescence display. ○ The sizes of the coatings shown in the horizontal planes in Figs. 1-4 are enlarged for clarity. In practice, the thickness of each cladding layer is only tens of microns. The two-element electroluminescent display shown in item 1) includes two lamp elements C and D. These lamp elements are stacked on a transparent front electrode. The transparent front electrode is an indium tin oxide (ITO) layer printed or deposited on a clear or transparent polymer sheet. The polymer layer 50 is the base of the lamp and is used to protect the surface of the display. Referring to the lamp C, a fluorescent substance layer 12a is deposited on the transparent front electrode 11 in a desired shape (the dielectric layer 13a is viewed from the direction E in FIG. 1 and then printed on the fluorescent layer 12a. The image formed by the mass layer i3a (that is, the shape viewed from the plane) is roughly the same as the fluorescent layer below. However, the dielectric layer can be about 2mm larger than the edge of the fluorescent substance area. The top of the electrical layer 13a thus forms the valley structure of the electroluminescent lamp. The electromagnetic and physical characteristics of the dielectric layer 13a make it possible to apply considerable lamp voltage to the front and rear electrodes I and this Can prevent the fluorescent substance from collapsing when the large voltage gradient is passed through the fluorescent substance.

In the lamp, electroluminescence is formed due to the electric field that excites the disk atoms, and then the disk atoms are in a grounded state because they emit radiant energy in the visible light spectrum. The resulting electroluminescence is emitted from the transparent front electrode to form a uniform phosphorescent illumination. In applications where a single-lamp display (i.e., the display has only a single-element c), the method of providing a conductive path to the rear electrode 14a to form an electric ballast is quite intuitive. The conductive path can be formed by connecting the front and rear electrodes to the edge contact of the electroluminescent lamp. However, when the path passes through the exposed portion of the substrate, a first dielectric insulator 30 must be provided between the fluorescent substance 12a and the rear electrode 14a. The structure of this lamp will be described in detail later. The conventional EL lamp shown in Fig. 2t can be manufactured by the following technology: An adhesion promoter such as "Vytel" is deposited on the transparent front electrode layer 11. The Vytel layer can promote the adhesion of the path and the tail bridge to the non-image exposed area (No fluorescent substance or rear electrode) the front electrode substrate. The colored fluorescent layer 12a is then printed on the lamp. The image printed on the EL lamp corresponds to the light receiving area. The thickness of the fluorescent layer 12a can be 45 to 55 microns And it can be fluorescent substance particles, which are individually coated on a glass-like fluorescent coating. This structure, called a micro-encapsulation, can eliminate the need for a protective layer, which is used to prevent the glare layer from getting wet. Dielectric The layer 13a is then stacked on the fluorescent layer 12a. The planar shape of the dielectric layer 13a is the same as that of individual fluorescent lamp elements. However, in a preferred embodiment, the dielectric layer may be larger than the edge of the glorious substance layer 12a. Approximately 2mm. The thickness of the dielectric layer 13a is approximately 14-18 microns.

Figure 1 shows a two-element lamp. In complex and / or large displays 'conducting paths must usually be made across the lamp area. These power paths must be insulated' to prevent leakage currents The front electrode is exposed through the conductive path and the lamp electrode or through which it flows. These paths must also each have a very small capacitive 'to avoid disturbing the lighting characteristics of the lamp element. To achieve this, the first ultraviolet dielectric insulator 3 〇Laying on top of the dielectric to form a bridge. Three layers of printing are sufficient to allow this insulator to form an effective deposit. UV dielectric insulators usually form an insulating path across the EL lamp area to isolate the conductive path below. First dielectric Layer to isolate the first conductive layer (front electrode) and form a minimum insulation thickness between the conductive layers behind the EL display = The first silver conductive path (not shown) corresponding to the external ground line (ie, the bus bar) is deposited around the lamp and it is finally connected to the contact area. At this stage, the rear electrodes 14a and 14b are also deposited on the lamp. Areas constitute individual lamp circuits. The shape of the back electrode corresponds to the area of the deposited illumination (or area of fluorescent material). These areas are connected by a conductive path that bridges the UV dielectric layer bridge to the contact area. Two UV dielectrics 16b or straddle layers are then deposited on the electrodes 14a, b. A second silver conductive path 17 (crossover path) is located above the UV dielectric straddle substrate 16b and the bridge 30, so that it is difficult or impossible to form In the case of direct connection, it constitutes a connection between paths or between a path and a lamp. The thickness of this silver conductive layer is 20-25 micrometers.

Description of Invention (7) The display is protected from moisture and constitutes insulation of the rear electrodes 14a, 14b. Approximately 5mm long conductive paths are exposed at the ends to form the connection between the power source and the busbar. The path 17, the second UV layer 16b, and the rear insulating layer 16a (indicated by the reference numeral 15) in Fig. 2 are stacked on the rear electrode 14a. A crossover path forms a conduction path for the power supply. The first UV insulating dielectric layer 30 is sandwiched between the fluorescent layer 13a and the back electrode 14a. This promotes insulation between the path and the exposed area of the front electrode (eg, between lamp elements). In the construction of the aforementioned conventional technology, the problem of the path and the corresponding insulating layer is that a relatively large step D is formed when the element is crossed. The discontinuity is marked by B in FIG. The deposition is thinner in the EL lamp area. These thin spots are easy to burn out and cause the lamp to fail ^ For reasons mentioned above and below, the present invention includes a single white dielectric layer uniformly deposited over the lamp region between the fluorescent layer 12a and the back electrode 14a. Fig. 3 shows the structure of such a lamp. Subsequently, referring to Figures 3 and 4, the novel manufacturing process for manufacturing such lamps will be described. The shape of the display in Figs. 3 and 4 is similar to that in Fig. 1. As shown in Fig. 4, the lamp C is rectangular and the lamp D is triangular. The blue-green fluorescent layers 12a and 12b are directly printed on a conductive transparent material or a semi-transparent substrate. The printing positions of the fluorescent layers 12a, 12b correspond to the aforementioned individual lamp regions. The adhesion promoter can be omitted. Next, the white dielectric layer 13 is uniformly printed on the entire area of the display ', leaving only the silver ground wire (or bus bar) in the area. Roughly uniform white dielectric 13 is an adhesion promoter for UV dielectrics. This paper applies Chinese national standards (CNSM4 specification (210 X 297 mm)). --Order ...!

Description of the invention (8) for UV The electricity is printed directly on the contacts in the non-lighting area of the EL display. In addition, looking at the lamp from the perspective of arrow E, the uniform white dielectric material blocks the conduction path 15. Another advantage of this configuration is that a uniform single white dielectric 13 avoids endpoint failure. The lamp of the conventional technology uses a uV dielectric to insulate the conductive path attached to the transparent front electrode. The end points of this structure's path are easily broken. The main advantage of the improved display structure of Figs. 3 and 4 is that the white dielectric makes the printing smooth. This is the best advantage of Figure 3 over the structure of Figure 2, where the 'white dielectric layer eliminates thin spots in the silver conduction path' These thin spots appear in the silver conduction path transition from the exposed transparent front electrode To multiple EL layer elements. The lamp of the conventional technology may form a step up to 60 micrometers at this discontinuity point, causing the lamp to burn out and malfunction. The lamp structure of the present invention smoothes the step so as not to burn the lamp. Figure 4 shows a cross-sectional view of a simplified electric incandescent lamp with a uniform white dielectric layer. Referring to FIGS. 3 and 4, the first UV dielectric insulating layer 30 is used to cover all connection paths. The dielectric layer 30 is completed in a single printing instead of three printings in the conventional technique. This dielectric layer prevents current leakage between the path and the front electrode. The method of laying out the conduction path is substantially the same as described above. However, as mentioned above, since a white dielectric having a thickness of about 25 micrometers has been previously printed, only one layer is required here. A layer gap of at least 30 microns is required between the substrate electrode and the conductive path.

Description of the invention (9) Guide paths are connected. These conductive layers form the back-end capacitor electrodes of the display fixture. The thickness of this electrode layer is 10-12 microns, and its shape corresponds to the shapes of the fluorescent substance layers 12a and 12b. The cross-sectional view is shown in FIG. The first UV dielectric jumper insulator 6b is then deposited on the silver electrode. Similarly, these jumper insulators are generally rectangular, or their shape may be determined by the shape of the image and the power supply path required for each element of the EL display. Next, a conductive jumper path 17 is deposited on the second UV path insulator. The conductive paths at the ends are then covered with conductive carbon to prevent exposure to silver pathways. A UV dielectric protection layer 16a is then printed on the entire back surface of the E display, thereby isolating the silver crossover path from the exposed silver image electrode. The part is shown in a long bar in Figure 4, so as not to obscure the details of the display. The area of about 5-1 Omm at the contact point of the power supply is not covered with a UV dielectric protection layer. Although the present invention is applicable to an electroluminescent lamp display with a single or a small number of elements, its greatest advantage appears in the wiring of a multi-element (lamp) EL display that requires a large number of bridge and conduction path elements. The applicant produced a prototype multi-element EL display with up to 16 individual lighting fixtures or lamp assemblies. One lamp assembly is the majority of individual lamp elements that are powered by a single switching or multiplexing signal. Therefore, for example, a luminaire with 16 individual light elements or light element assemblies must have a large number of bridges' and must form an effective insulation between the conductive bridges and the silver rear electrodes and the exposed rigid electrodes they span '' As mentioned above, the known structure will guide the paper size to Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page) Consumption cooperative seal * 1 ^ I -------- ^ ---------- ^ I ------- i__ 12 3 ϋ 3 9 4 A7 _________ ΰ7 ____ 5. Description of the invention (1 〇) Causes the transition area between the front electrode and the lamp area to burn out. As the number of transition zones increases, the situation of burnout and lamp failures will be unacceptable. ^ The present invention may provide more immunity by allowing more bridges to exist, enabling manufacturers to manufacture extremely complex luminaires. In addition, the reliability of the display manufactured according to the present invention, especially the reliability of the end portion, is improved by the presence of a uniform white dielectric. Therefore, the present invention can provide an improved electroluminescent display and a method for manufacturing the same. This improvement is based on the use of existing chemical products without significantly increasing the cost of manufacturing lamps. Highly complicated luminaires can be manufactured according to the present invention, and their durability and reliability are improved. In the description, the same reference numerals are used for similar components, and their function is equivalent to each component being disclosed separately. Although the above is an example to illustrate the present invention, we should still understand that 'this invention can be variously modified and improved without departing from the scope or spirit of the scope of the attached patent application.
