CRT display set and optical device having means for accurately positioning the CRT |
摘要 |
The disclosure relates to display sets wherein the image produced by a cathode-ray tube is displayed on a display screen by means of an optical device. It relates more particularly to means for facilitating the relative positioning between the cathode-ray tube and the optical device. The cathode-ray tube comprises a bulb having one end closed by a transparent plate bearing an cathodoluminescent screen. In one characteristic, the transparent plate is greater than the bulb and comprises a peripheral part that extends beyond the bulb so as to constitute a reference marker of the position of the cathodoluminescent screen. FIG. 1.
