摘要： A tension mask frame assembly for a color cathode-ray-tube including a frame having four respective sides, two of the sides paralleling each other and having insert receiving brackets for supporting strand termination inserts therein and vertical mask strands welded to said termination inserts. The strands have a plurality of cross-wires extending perpendicular to the strands and attached thereto by a conductive bonding material. The wires and termination inserts are composed of materials having a first coefficient of thermal expansion. The frame and receiving brackets are composed of materials having a second coefficient of thermal expansion. The termination inserts thermally expand and contract independently of the frame and receiving brackets, whereby movement of the strands in the horizontal dimension is controlled by thermal expansion and contraction of the termination inserts and cross-wires.

摘要： A light-absorbing matrix 23, having openings therein, is formed on an interior surface of a faceplate panel 12 of a cathode-ray tube 10 by providing a photoreceptor thereon, electrostatically charging the photoreceptor 72 to a substantially uniform level of charge, and exposing the photoreceptor to light through openings 33 in a color selection electrode 24 to selectively discharge the more intensely illuminated areas of the photoreceptor, without substantially discharging the less intensely illuminated areas. The photoreceptor 72 comprises a plurality of layers including a photoresist layer 56, a conductive layer 62, and a photoconductive layer 66. The openings 33 in the color selection electrode 24 have a dimension substantially greater than the dimension of the openings in the resultant matrix 23.The photoreceptor 72 is contacted with a liquid toner having charged pigment particles which form toner lines 84 on the less intensely illuminated areas of the photoreceptor. The photoreceptor 72 is exposed to UV radiation to selectively change the solubility of the photoresist portion 56 thereof into areas of greater and lesser solubility. The photoreceptor 72 is serially developed to expose portions of the interior surface of the panel 12, while leaving the areas of lesser solubility intact. Next, the interior surface of the panel and the areas of lesser solubility are coated with a matrix suspension which is dried to form the matrix 23. The areas of lesser solubility and the overlying light-absorbing matrix material thereon are removed, thereby forming in the matrix 23 a plurality of openings having a width less than the width of the openings 33 in the color selection electrode 24.

摘要： A cathode ray tube may utilize a focus mask color-selection structure. The focus mask structure is susceptible to localized, transient short circuit events, or breakdown events. These events may be caused by conductive particulates that become free within the cathode ray tube and provide a short circuit between first and second layers of the focus mask. The breakdown events are undesirable because they may result in cross-strand currents causing mask strand magnetization that can interfere with a video image on the screen of the cathode ray tube. A rapid degaussing operation is initiated during the next subsequent vertical blanking period following detection of the breakdown event.

摘要： A cathode ray tube may utilize a focus mask color-selection structure. The focus mask structure is susceptible to localized, transient short circuit events, or breakdown events. These events may be caused by conductive particulates that become free within the cathode ray tube and provide a short circuit between first and second layers of the focus mask. The breakdown events are undesirable because they may result in cross-strand currents causing mask strand magnetization that can interfere with a video image on the screen of the cathode ray tube. A transformer rapidly senses random changes in a voltage or a current supplied to the second layer of the focus mask. A pulse waveform generator is coupled to the transformer and provides a pulse waveform responsive to the sudden change in voltage or current.
