Apparatus for automatic adjustment of convergence of a projection television and method to automatically correct the bad convergence of a projection TV

摘要

"Apparatus for automatic adjustment of convergence of a projection TV and method to automatically correct the bad convergence of a projection TV.With the present invention refers to a method and a device to adjust the convergence of a projection TV are further disclosed.The apparatus includes a display device in which it is designed an image and at least one element of the light sensor (101) is provided around the display device.The element of the light sensor (101) is composed of first and second subsensores (101A.101b) which generates output signals of separated as a pattern of alignment designed moves over the subsensores (101A, 101b).The apparatus also includes a microprocessor that calculates a vector adjustment of convergence to obtain a location of the element light sensor (101).From what has been made prior to the correction of convergence. The location of the element light sensor (101) is obtained by analyzing the output signals.Using the apparatus and method of the present invention, the convergence error of projection TV can be corrected quickly and accurately.
