A printing system includes a printing device, and a printing data processing device. A status data generating unit generates status data indicating a status of the printing device. A storing unit stores status image data that graphically indicates a content of the status data. A text data generating unit generates status text data that explanatorily indicates a content of the status image data with words. A data editing unit edits the window data to include the status text data and the status image data. A display unit displays the window by using window data such that the window displays an image corresponding to the status image data and a text corresponding to the status text data. A specifying unit specifies the text on the window. A voicing unit voices the specified text based on the corresponding status text data.

To detect a dark current when an abnormal discharge occurs between an anode and respective electrodes, on an inner surface of a front substrate, a dark current detection electrode is formed in a state that the dark current detection electrode is positioned adjacent to the outside of a screen display region on which an anode is formed and on a plane substantially equal to a plane on which the anode is formed. Then, between an electrode terminal of the dark current detection electrode and a ground, an ammeter which detects the flow of a dark current and a DC power source having a preset voltage value which is more or less lower than a high voltage supplied to the anode are connected in series.

摘要:
The present invention provides an image display device, in which a top electrode is selectively separated by laser ablation for each scan line. As the laser, a third harmonic wave of YAG laser with a wavelength of 355 nm is used. By setting film thickness of the interlayer insulator 15 to 100 nm and film thickness of a field insulator 14 to 140 nm, reflective spectrum has the minimum value near a wavelength of 355 nm, This laser beam is projected from a top electrode 13 toward a substrate 10. A part of the projected laser beam 20 is reflected by the top electrode 13, but most of the laser beam pass through a field insulator 14 and the interlayer insulator 15 and is reflected by a bottom electrode 11. As the result of interference of these two reflection waves, the minimum value appears in reflection spectrum. In this case, the laser beam is mostly absorbed near boundary surface between the top electrode 13 and the interlayer insulator 15. The top electrode 13 is processed by ablation (melting and evaporation), and the top electrode 13 is separated at this portion. By utilizing interference phenomenon in this manner, no damage is given to the interlayer insulator 13, the field insulator 14, and the bottom electrode 11, which serve as underlying layers, and the top electrode 13 can be selectively cut off.
