ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display which can be used in a computer display unit or television receiver or the like, and to electronic devices suitable for such a display. In particular the invention is one which enables a display device which is precise yet large size to be easily realized.
2. Description of Related Art
Heretofore, CRT or liquid crystal displays or the like are used for example in computer display units. Furthermore, there are many situations where displays which use light emitting diodes are applied to large size display units provided for example on the walls of buildings.
Moreover, there is also the situation where for a display unit set up outdoors, an overall large size display unit is realized by horizontally and vertically stacking a plurality of CRT receiving sets.
In the conventional construction of a CRT display or liquid crystal display or the like, in the case where a large size display unit is to be realized, generally the dimensions of the display screen itself are made large size, that is, the dimensions of one display are made to a desired size. However with such a method, the dimensions of each part of the manufacturing line must also be made large corresponding to the desired dimension of the display. Furthermore, the handling of the semi-finished products during manufacture is difficult. Hence there is naturally a limit to the size which can be manufactured.
On the other hand, with a large size display which uses light emitting diodes, the construction is such that individually manufactured light emitting diodes are assembled together to make up the display. Therefore, even though a large size display is manufactured, the dimensions of each part of the manufacturing line need not be large for this. Hence this is advantageous as a method of manufacturing large size displays. However, with actual large size displays which use light emitting diodes, it is assumed that these will be viewed from a distance. Therefore, the diameter of the individual light emitting diodes is made large and the pixel pitch is coarse. Consequently, for close up viewing use as with large size household displays, the pixels are too coarse and hence this is unsuitable.
Furthermore, with a construction where a plurality of CRT receiving sets are stacked together to give a large size display unit, image precision is obtained. However this has the drawback in that since the frame part of the CRT receiving set exists between the respective CRT receiving set pairs, the image is divided at that part.
BRIEF SUMMARY OF THE INVENTION
The present invention addresses such unsolved problems of the conventional technology, with the object of providing a construction for a display where the image is precise, and which is also applicable to large size, and to provide a construction for electronic devices suitable for such a display.
In order to achieve the above object, a display, being a first aspect of the present invention, is one in which a plurality of display blocks comprising a plurality of pixels, and a terminal portion into which signals can be input for controlling optical characteristics of each of the pixels, are linked together so as to be continuous in at least one of a horizontal direction and a vertical direction, and signals are input in parallel to each of the display blocks via the terminal portion. Here “optical characteristics” indicates for example transmissivity or the like of a liquid crystal in a liquid crystal display device.
Furthermore, a display, being a second aspect of the present invention, is one in which a plurality of display blocks comprising a plurality of pixels, and a terminal portion into which signals can be input for controlling light emitting characteristics of each of the pixels, are linked together so as to be continuous in at least one of a horizontal direction and a vertical direction, and signals are input in parallel to each of the display blocks via the terminal portion.
In order to achieve the above object, a display, being a third aspect of the present invention, is one in which a plurality of display blocks comprising a plurality of pixels containing organic EL elements, and a terminal portion into which signals can be input for controlling light emitting characteristics of each of the pixels, are attached to a transparent substrate so that a display surface faces the transparent substrate side and so that the display blocks are continuous in at least one of a horizontal direction and a vertical direction, and signals are input in parallel to each of the display blocks via the terminal portion.
Moreover, a fourth aspect of the present invention is that in the display being the second or third aspect, a power supply being supplied in parallel to each of the display blocks via the terminal portion.
Furthermore, a fifth aspect of the present invention is that in any one of the second through fourth aspects, a terminal portion which respectively conducts horizontally extending wiring and vertically extending wiring inside the display block being gathered at one side of each display block, so that the terminal portion is only provided at one side of the display block.
A sixth aspect of the present invention is that in the display, being the second through fifth aspects, the terminal portion being provided so as to be positioned on a rear side rather than a periphery portion of the display block.
Moreover, a seventh aspect of the present invention is that in the display, being the second through sixth aspects, the display blocks having a construction in which a plurality of microstructures made with electronic circuit elements are disposed on a substrate.
Furthermore, an eight aspect of the present invention is that in the display, being the seventh aspect, a drive circuit for the pixel being made in the microstructure.
On the other hand, in order to achieve the above object, a ninth aspect of the present invention is that in an electronic device comprising horizontally extending wiring and vertically extending wiring, there being provided a plurality of microstructures arranged on a substrate at positions corresponding to those where the horizontally extending wiring and vertically extending wiring intersect, and in the microstructures there being provided a portion of the horizontally extending wiring and the vertically extending wiring which includes a portion where the two wiring non-contactingly intersect with each other, a first direction conversion wiring which conducts with one of the horizontally extending wiring and the vertically extending wiring and which is taken out from the microstructure in the same direction as the other of the two, a second direction conversion wiring which does not conduct with the other wiring inside the microstructure, and which is taken out from the microstructure in the same direction as the first direction conversion wiring and so as to be adjacent thereto, and pairs of the horizontally extending wiring of the microstructure which are adjacent in the horizontal direction being connected, and pairs of the vertically extending wiring of the microstructure which are adjacent in the vertical direction being connected, and furthermore the first direction conversion wiring and the second direction conversion wiring of adjacent microstructures being selectively connected, so that end portions conducting with the horizontally extending wiring and the vertically extending wiring are gathered at one side of the substrate.
In order to achieve the above object, a tenth aspect of the present invention is that in the electronic device, being the ninth aspect, plurality of microstructures with drive circuits being arranged on a substrate, and the microstructures being connected by wiring, and a signal can be supplied from the outside to a terminal portion of the wiring.
Here in the first or second aspects of the present invention, since the display is constructed with a plurality of display blocks linked together, a display of optional dimensions can
