リクス画面を得る。Generally, the following method is used to form a black matrix screen for a color picture tube. After applying photosensitive adhesive to the inner surface of the glass panel, the shadow mask opening pattern is exposed to light through a shadow mask, and after development, a light absorbing material is applied, and after drying, the photosensitive resin film is cured by exposure to a release agent. By simultaneously removing the light-absorbing material, a plaque matrix screen is obtained.

て決まる。The uniformity of this black matrix screen, that is, the size of the black matrix holes or stripes on which the shadow mask aperture pattern is printed, is a key factor in determining color unevenness and white uniformity of the color picture tube. Therefore, the size of the black matrix hole or stripe is
It is always necessary to form it to a predetermined size. This size is determined by the amount of exposure during light editing relative to the sensitivity of the photosensitive resin film.

る。Conventionally, such internal exposure has been performed using an exposure apparatus as shown in FIG. That is, it consists of a light source 20 fixed at a predetermined position, a filter 11 that adjusts the amount of light emitted from the light source section 10, and a correction lens 12 that makes the previous light ray approximate the trajectory of the electron beam. °
[There is. A shadow mask 14 is attached to a glass panel 15 coated with photosensitive balm (not shown), placed on the plate 13 of the exposure device, and a predetermined amount of butter is baked. Furthermore, a photodetector 16 is provided in a part of the light source section,
It has a light weight control device for detecting and controlling the illuminance of the optical path 1.

度を精度よく、制御することが困難であった。However, the photodetector was only sensitive to a portion of the light source. Q: It was not possible to detect the illuminance of the light source used for actual printing, making it inconvenient to obtain the desired dots or stripes. - Since the blade photodetector is installed next to the light source, it is strongly exposed to thermal radiation and ultraviolet rays, causing the C1 temperature to rise, causing fluctuations in the detection signal and deteriorating the photodetector. It was difficult to control.

。A cooling pipe 23 is attached to a lamp house 22 having a light source section 21 made of a high-pressure mercury lamp 20. One or more photodetectors 24 are present between the correction lens 12 and the light source section 21 at a position where they do not interfere with the light rays emitted from the light source for printing a shadow mask pattern on the glass panel. Furthermore, the photoreceptor 24 has a water cooling pipe 26.3000
A spectral filter 27 that selectively absorbs light with a wavelength of A to 5000 A, and a fringe 28 that adjusts the amount of light from the light source. and a holder 29 for holding them.

1の照度を制御することができる。When using an exposure apparatus having this light area control device, the photoreceptor 24 converts the light emitted from the mercury lamp 20 into the spectral filter 2.
7° C. through the ridges 28, and the photoreceptor 24 is cooled, so it is not damaged by heat and can be used for a long time. Further, since the photodetector 24 is placed away from the light source section and on the correction lens side, it is possible to detect the light actually used for exposure, and the light source section 24 can be
1 illumination intensity can be controlled.
