Abstract: PROBLEM TO BE SOLVED: To achieve two-dimensional peak wavelength, brightness, and chromaticity measurement by detecting the wavelength shift amount of a measuring object whose spectrum shifts in wavelength even when the spectrum shape is the same.
SOLUTION: In the wavelength shift amount detecting method, first, the measuring object 21 having a spectral characteristic of each primary color signal component is photographed by a camera 11 having the spectral sensitivity characteristic of each primary color signal component larger than the spectral characteristic of the measuring object 21. Next, output of the spectral characteristic of the measuring object 21 of one primary color signal component, of spectral characteristic of the measuring object 21 included in the spectral sensitivity characteristic of each primary color signal component of the camera 11, is compared with output of the spectral characteristic from the spectral sensitivity characteristic of another primary color signal component of an adjacent wavelength using output ratio. When the output ratio varies, it is detected that the wavelength of the spectral characteristic of the measuring object 21 is shifted by the amount corresponding to the output ratio.

Abstract: PROBLEM TO BE SOLVED: To form a uniform photosensitive liquid coating film on the inner surface of a flat panel and suppress the residual resist in a panel corner part by setting the panel revolution angle to a specified angle, and injecting a photosensitive liquid to the flat panel inner surface at a low speed rotation. SOLUTION: A PVP photosensitive liquid 23 is injected to the inner surface of a flat panel 31 through a nozzle 22 while the flat panel 31 is rotated at a low speed with a revolution angle of 103-90 deg., preferably within the range of 100 deg.-900 deg., for example, at 100 deg.. The low-speed rotating number is preferably 5-20 rpm. The flat panel 31 is rotated at a high speed to perform the shaking for formation of a uniform thickness, and then rotated at a high speed in the same revolution angle state of 100 deg. in drying process to dry the photosensitive liquid coating film by a far infrared drying heater, and air is also blow to the panel, corner part in a fixed flow rate. As the high-speed rotating number, 120-250 rpm is preferred. As the air flow rate, 180 l/min or more is preferred since the resist residue can not be improved with less than 180 l/min.

Abstract: PROBLEM TO BE SOLVED: To prevent darkening that is produced in the vicinity of the corner part of a CRT by limiting the temperature difference between the central part and the corner part on a effective screen on the inner surface of a panel to the specified range in a drying process for forming a sensitive agent when the sensitive agent which becomes insoluble by light is applied to the inner surface of the panel, dried, then exposed through a color selection electrode to form carbon. SOLUTION: In a drying process for forming a sensitive agent, a panel 1 is held with a holder, conveyed onto a heater 5, and a PVP film is dried. The temperature of a central part 10 of the panel 1 coated with a PVP sensitive agent 3 is set to 47 deg.C and that of the corner part 11 is set to 44-40 deg.C, preferably to 42 deg.C. The temperature of ceramic heaters 51 -54 of the heater 5 is controlled so that the temperature difference of the central part 10 and the corner part 11 of the face panel 1 is set to 5±2 deg.C, then the PVP sensitive agent 3 is exposed with ultraviolet rays such as a mercury lamp through a color selection electrode. Uneven black and darkening that is produced in the corner part of a CRT are reduced.
