IPC: H01J9/227
Filed: 1984-02-08
Abstract: PURPOSE:To obtain a good color picture tube without color mixture by adjusting humidity in a bulb by means of mixing two kinds of air with different humidity when applying light exposure and phosphor. CONSTITUTION:At each stage of an air-developing process for forming each stripe pattern 4-7, humidity in a bulb is adjusted by using a mixture of, for example, room air of 40-50% humidity, 20l/min flow rate and, for example, high-pressure air of 15-20% humidity 40-70l/min flow rate. In this case, it gives a good result for forming a phosphor screen to increase mixing ratio of high-pressure air and thereby, decrease humidity further as the subsequent applications of light exposure and phosphor are carried out later. Thus, the amount of phosphor adhering to a photosensitive adhesive coating can be varied and humidity in the bulb suitable for applying each phosphor is easily adjusted, by changing mixing ratio of high-pressure air and room air.
