Abstract
The operator manipulated rotary knob, sliding knob, depressible button or the like of an electrical circuit control device is situated at the face of an image display screen within the image display area. This enables display of calibration marks and/or other graphics pertinent to operation of the control including at locations immediately adjacent to the operator manipulated component. The graphics may change instantly when the function of the control is changed. Conductors for connecting the control device with the controlled circuit extend along a front or back surface of the transparent cover plate of the display or an overlay cover plate within the image display area. The conductors, which may be opaque or transparent, are positioned to avoid or minimize obscuring of images by the conductors. At least portions of the conductors overlay zones which are between the parallel rows or columns of image pixels and may be angled relative to the rows and columns and/or be spaced apart by a distance which is not an integral multiple of the spacing of the rows or columns.
