<p><P>PROBLEM TO BE SOLVED: To fetch an image without being affected by dispersion in electric characteristics of sensors and transistors in a plane display device in which the display pixels are formed in matrix form on an array substrate, and a plurality of photosensor pixels are formed on the array substrate. <P>SOLUTION: In the plane display device, a display area is divided into a plurality of processing blocks, a plurality of photosensor pixels 27 are formed on each of the processing blocks. The plane display device comprises: a precharge signal supply unit for supplying precharge signals to the respective photosensor pixels 27a; a reading unit for acquiring reading signals output from the respective photosensor pixels 27 according to intensities of light beams radiated on the respective photosensor pixels 27 while the precharge signals are supplied to the respective photosensor pixels 27; and a storage unit for storing data relating to the precharge signals for the plurality of photosensor pixels 27 in the corresponding processing blocks. The precharge signal supply unit supplies the precharge signals to the respective photosensor pixels 27 on the basis of the data. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
