Abstract
PURPOSE:To simplify the structure as well as to ensure a stable projected picture, by mounting a deflecting yoke having an uneven magnetic field distribution to the CRT. CONSTITUTION:The CRT10 contains the 1st and 2nd beam benders 17 and 18 that give an inclination of a certain angle to the center axial line of the electronic beam of an electronic gun 16 against the vertical line to the fluorescent screen of the CRT10. A deflecting yoke 9 having an uneven magnetic field distribution is mounted to such CRT10. In such an extremely simple mechanical constitution, a sufficient compensation is secured for a picture distortion on the projection screen 4. As a result, an economical and stable picture can be obtained without using any complicated electrical compensating circuit.
