    IBM use for UDC TOLED


    New patent app from IBM


    [0002] The present invention generally relates to computer interfaces used to input information relating to a physical document. More particularly, the invention relates to a device for capturing and displaying handwritten annotations and a computer system using such a device.
    According to the invention, the apparatus further comprises a transparent electro-luminescent display 13 adapted to display captured handwritten annotations. This display 13 is of the type of a transparent organic bright light-emitting device. In a preferred embodiment of the present invention, the display 13 comprises a substrate having an array or a mesh formed by a plurality of first and second lines. The first lines correspond to transparent scanning lines and the second lines correspond to transparent data lines. These first and second lines cross one other and an electro-luminescent element is located at each intersection of the scanning and data lines. Such a light-emitting display, with a passive matrix, may be made of an array of Transparent Organic Light Emitting Devices (TOLEDs), which are commonly used to create vision area displays on windshields, cockpits, and so forth. TOLEDs are today manufactured with standard silicon semiconductors. An example of light emitting foil technology that would be possible to use here is that used for the TOLEDs manufactured by UNIVERSAL DISPLAY CO.
