Time sequential information is written to a first light-to-light conversion element, and the thus-written time sequential information is thereafter written from the first light-to-light conversion element to a second light-to-light conversion element in the form of two-dimensional information. With this arrangement, the time sequential information can be converted with high resolution to the two-dimensional information in real time operation without involving a brightness gradient or shading. |

DETAILED DESCRIPTION With the foregoing drawbacks of the prior art in view, it is an object of the present invention to provide an improved light-to-light conversion method which is capable of converting the time sequential information with high resolution to the two-dimensional information without the necessity of a costly and time-consuming process.
Another object of the present invention is to provides a high resolution display unit for reducing the light-to-light conversion method into practice.
In brief, according to the present invention, time sequential information is written in a first light-to-light conversion element.
The written or recorded information is read out from the first light-to-light conversion element in the form of two-dimensional information which in turn is written to a second light-to-light conversion element.
Thereafter, the information written to the second light-to-light conversion element is displayed.
More particularly, according to a first aspect of the present invention, there is provided a light-to-light conversion method for converting time sequential information into two-dimensional information, which comprises: providing first and second light-to-light conversion elements disposed in confronting relation to one another; writing time sequential information to the first light-to-light conversion element by using first electromagnetic radiation; and irradiating the first light-to-light conversion element with second electromagnetic radiation to read the information from the first light-to-light conversion element and then write the thus-read information to the second light-to-light conversion element.
According to a second aspect of the present invention, there is provided a light-to-light conversion method for converting time sequential information into two-dimensional information, which comprises: providing a light-to-light conversion element composed of at least a light storage layer, a photoconductive layer and a photomodulation layer disposed in confrontation in the order named; writing time sequential information to the light storage layer by using first electromagnetic radiation; and writing the information to the photoconductive layer by using second electromagnetic radiation transmitted from the light storage layer
