<P>PROBLEM TO BE SOLVED: To solve the following problem; on a cellular phone mounted with a CCD sensor or a CMOS sensor and provided with a camera function and a cellular phone with a built-in fingerprint sensor for personal identification, these sensors are not integral with an image display part, therefore, the equipment has to be increased in packaging density. <P>SOLUTION: An active matrix type organic EL display apparatus 10 in which pixels 11 including light emitting circuits 22 and light receiving circuits 23 are arranged in a matrix form is configured so that image information can be fetched without arranging the CCD sensor and the CMOS sensor, further without a touch panel, by converting the light receiving signals outputted to light receiving signal lines 19-1 to 19-n from the light receiving circuit of each pixel 11 into digital light receiving signals through A-D converter circuits 15-1 to 15-n to output, and also the fetched image information can be externally outputted in digital data. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
