Abstract: PROBLEM TO BE SOLVED: To provide a display device made so as to hold a grid electrode at an exact location. SOLUTION: A rim 26 made of glass or a ceramic material at a high temperature is mounted on an alloy sheet in a through hole and electron is focused on a fluorescent layer 33 by using voltage applied on the sheet. An optional insulating layer is formed on the sheet, an optional grid electrode is formed on the insulating layer, and addressing and focusing are performed. Because the rim 26 holds tensile force on the alloy sheet according to cooling, a cathode 16, the alloy sheet for pixel dots and holes of the grid electrode are properly aligned and held without being affected by a change in temperature. When the rim 26 is mounted on a cathode plate and a face plate 12, an exact aligning process is completed and assembling of a device is simplified. By using the thin rim 26 and a substrate, thickness of a combined electrode structure becomes 3 mm or below, a distance between the face plate 12 and a back plate 14 becomes 10 mm and the device becomes suitable for an ultrathin large-sized screen display.

Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a device and facilitate manufacture by practically overlapping a set of each pixel dots existing in a luminescent layer with an image of a set of corresponding cathode elements in the luminescent layer through a corresponding hole existing in a layer of micro electron lens structure. SOLUTION: Each of RGB phosphors 33 is arranged in a two-dimensional array, each of its pixel dots is overlapped with a corresponding set of an FE cathode 14 and with a corresponding hole of holes of the two-dimensional array existing in a conductive layer 50, as viewed from the observation direction 52. Pixel dots 33R, 33G, and 33B are overlapped with sets 14r, 14g, and 14b of the cathode elements and with corresponding holes of the conductive layer 50. The array of sets of the FE cathode 14 forms a row and a column of the two dimensional array. A power scanning potential of a controller is continuously applied to the row of the sets of the cathode elements, a data potential is applied to the column of the sets of the cathode elements, XY addressing and brightness of the two-dimensional array of each of RGB phosphors are controlled to display an image.

Abstract: Strips of field emitters (30) arranged in rows overlap grid electrodes (32, 32', 32'') when viewed in the viewing direction (36) to define pixel dots. Scanning electrical voltages are applied to the rows of field emitters (30) to perform scanning and data potentials are applied to the grid electrodes (32, 32', 32'') to control the brightness of the display. Potentials applied to the grid electrodes (32, 32', 32'') also focus the electrons from the field emitters (30). A metal mesh with grid electrodes (32, 32', 32'') fabricated thereon to form an integrated structure greatly simplifies the manufacture of the display.
