<p>PROBLEM TO BE SOLVED: To make correctible with the corrective information of a small amount even when a large number of electron emission elements are provided in correcting in an approximately uniform manner the electron emission characteristic of a plurality of electron emission elements provided in a matrix. SOLUTION: The corrective information on a current drive circuit, the corrective information on the reactive element current in the wiring of the row direction, and the corrective information on the variance in electron emission efficiency are obtained in advance, a target emission current value is obtained using the information, the current running in the selected element is obtained, the current running in the wiring in the row direction to which the selected element belongs is obtained, and the current value to be set to the current drive circuit is obtained (S501-504) by correcting the input/output characteristic for every channel of the current drive circuit. In the step S505, the set current value obtained in the step S504 is stored in a non-volatile memory.</p> |
