摘要： A convergence correcting apparatus is used in a projection television receiver including a CRT (1010) having an aspherical fluorescent screen (P₁) and a projection lens apparatus which is attached to the display screen of the CRT and has aspherical plastic lenses (101, 103, 104). In the digital convergence correcting apparatus, a digital memory (8) stores digital correction data corresponding to correction values of convergence adjustment points (201) indicative of a plurality of points on the display screens divided in the horizontal and vertical directions. A multiplexer (15) reads out predetermined digital correction data from the digital memory (8) and time sharingly multiplexes. At least one digital/analog converter (19) receives the time sharingly multiplexed data from the multiplexer (15) and generates an analog signal. Sample and hold circuits (26, 26′) extract a predetermined correction signal from the analog output of the digital/analog converter (19) and sample and hold them. The convergence correcting apparatus is driven in accordance with the respective correction signals held by the sample and hold circuits (26, 26′).
