Definitions
- the present invention relates to a large display unit which is used outdoors for advertisement, announcement or the like, and more particularly, to a large display unit in which a plurality of display units are combined to constitute a single large display, the display units disposed in rows and columns each displaying one character.
- a display unit of this kind is described in DE-A-3 037 500.
- Fig.4 shows a display unit 20 of similar kind.
- a display panel 21 of the unit 20 made of hard metal or resin is formed with display windows 21a in the form of, for example, 24 x 24 matrix.
- a light emitting element holder 22 made of, for example, a printed circuit board is mounted on the back of the display plate 21.
- Light emitting elements such as light emitting diodes (LED) are mounted on the holder 22 to face the display windows 21a and display illuminated dots.
- a driver circuit board 23 is mounted on the back of the light emitting element holder 22 to receive a character code from an external circuit and convert it into suitable drive signals which are supplied to the light emitting elements to display a corresponding character.
- the display unit 20 of this type is mainly intended to be used outdoors, it is housed within a water proof casing 24 provided with a water proof connector 24a. Further, the display windows 21a are also covered with glass to seal it from external environment. Thus, the entire structure of the display unit 20 is made water proof.
- the conventional display unit 20 is associated with many problems much as in the following because of the rigid structure thereof:
- the display unit comprises a predetermined number of display dots each made of light emitting elements and disposed in matrix manner relative to a display structure, wherein the light emitting elements of each of said display dots are mounted on a separate printed circuit board, and said display structure is made of flexible sheet members which sandwich said display dots which are attached by means of adhesive agent or the like.
- a sheet type large display unit (hereinunder referred to simply as a display unit) is generally indicated by reference numeral 1.
- a display surface member 2 of the display unit 1 is adapted to be mounted with display dots 3 disposed in matrix similar to the conventional. For example, 18 x 10, 24 x 24 dot matrix or the like may be selectively used in dependence upon a desired character resolution.
- display dots 3 disposed in matrix similar to the conventional. For example, 18 x 10, 24 x 24 dot matrix or the like may be selectively used in dependence upon a desired character resolution.
- a character for example, Chinese character as shown in Fig.2 can be displayed.
- One character is generally displayed on one display unit 1.
- the display unit 1 is shown in Fig.3, wherein the display surface member 2 generally of square shape is made of a sheet type transparent resin rich in flexibility, the reverse side of which is coated with an adhesive agent.
- Each of the display dots 3 is constructed of a desired number of light emitting elements 3b such as light emitting diodes (LEDS) mounted on a substrate 3a such as a printed circuit board.
- LEDS light emitting diodes
- 576 display dots 3 are used for a 24 x 24 dot display unit, and each display dot 3 is connected by lead wires 4 to a driver circuit (not shown) to drive it in a specific drive method such as dynamic, static or other drive methods.
- the display dots 3 on the substrate 3a and the lead wires 4 are fixedly attached to a back sheet 5.
- the back sheet 5 is covered with the display surface member 2 to fixedly attach them together, to thus assemble the display unit 1 of this invention.
- the substrate 3a for mounting the display dots 3 may use a printed circuit board either of hard or soft material.
- the attachment among the display surface member 2, display dots 3 and back sheet 5 may be effected using an adhesive agent, or other means such as high frequency welding whereby peripheral portions thereof are welded.
- colors of the light emitting elements 3b disposed within each display dot 3 may use red, yellow and green. To selectively activate the light emitting element, it becomes possible to realize a display unit 1 of three colors.
- the display unit 1 is constructed of the display surface member and back sheet which are both made of flexible material, the entire structure of the display unit 1 is flexible.
- the display surface member 2 and back sheet 5 are made of sheet material so that the display unit 1 becomes thin and light weighted.
- the display dots 3 are covered by the display surface member 2 and back sheet 5 so that a sufficient water proof performance is realized.
- a water proof connector and water proof driver circuit may be provided on the display unit 1 as conventional.
- the display unit of this invention is applicable to various fields in practical use due to its sheet structure, and has the following advantages:
