ABSTRACT:
A cathode ray tube mounting apparatus and method for use in a video display terminal or television receiver. An adhesive is applied to either the inside perimeter of the bezel of the cabinet or to the perimeter of the front surface of the cathode ray tube. The cathode ray tube and bezel are then placed in contact and pressed together. Before the adhesive has set, the position of the cathode ray tube is adjusted to align the cathode ray tube with the horizontal center line of the cabinet. In another embodiment, a sheet of material is attached to the inside of the front portion of the cabinet. The adhesive is applied to either the sheet of material or to the front surface of the cathode ray tube. The cathode ray tube and front portion of the cabinet are then mated as before. The sheet of material is used to compensate for any thermoexpansion mismatch between the cathode ray tube and the cabinet.
