![]() It costs substantially more to manufacture than a conventional tube. This year, after a sustained effort Zenith engineers developed prototype automated machinery for stretching the shadow masks with the required precision.Ī major drawback to the flat screen has been its enormous manufacturing expense. Zenith already has invested $40 million in flat-screen manufacturing facilities in addition to $10 million to $15 million in research and development. While one European company and some Japanese companies have developed flat screen-type tubes in their labs, they have been blocked from marketing them by Zenith`s multiple patents on the process. But this January the company expects two additional computer companies to begin using its new monitor. Zenith does not directly market flat screens to the consumer. Under a new arrangement, Zenith would continue to manufacture the flat screens for Zenith Systems, which currently is the only company marketing a flat monitor. Shortly thereafter, Zenith spun off Zenith Systems to France`s Groupe Bull. Zenith introduced flat screens on computer monitors sold by its Zenith Data Systems division. In addition, color liquid crystal displays over 8 inches diagonally in size are prohibitively expensive to manufacture. ![]() Necessary for true, full-size, high-resolution displays. However, liquid crystal displays lack the brightness and picture elements (pixels) Liquid crystal displays also have a completely flat screen. A flat screen dramatically reduces glare and reflections. Zenith takes this one step further with an OCLI (Optical Coating Laboratories Inc.) anti-glare, anti-static coating.īut the most obvious benefit of the breakthrough was a completely flat screen face. Increased brightness permits the use of ''blacker'' low-light transmission glass to increase contrast. This enabled Zenith to increase the power of the beam to make the phosphors glow more brightly. This results in higher resolution.Ī rigid mask resists flexing even under the higher temperatures of a more powerful electron beam. ![]() The mask doesn`t flex, reducing the need for a large black area between phosphor dots, and permitting increases in both the size and number of phosphor dots. The flat screen makes possible a number of picture improvements. They then designed a flat screen to work with the flat tension mask. Zenith engineers developed a technique of stretching and holding the shadow mask flat under great tension from all sides. Zenith broke the mold in 1987 with its flat tension mask computer monitor. But ultimately the extra labor has paid off, because in bonding a curved screen to the ''funnel,'' as the rear of the TV tube is called, there is less chance of an implosion when the air is evacuated. This curvature means screens must be manufactured one at a time, rather than stamping many from a single sheet of glass. The face of the TV picture tube on all existing consumer TVs is either a portion of a sphere or a cylinder. It is much easier to blow glass in rounded rather than square forms.
