Title:
DISPLAY DEVICE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3614286
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent electric discharge from occurring while preventing a device large and suppressing the increase of the cost by covering one part of electronic parts with an insulating heat shrinkable tube made to shrink by heat.
SOLUTION: The display device 1 is constituted so that the terminal part 10 of a light emitting diode 3 positioned between a printed wiring board 2 and a case 6 is covered with the heat shrinkable tube 27 made to shrink by the heat. The tube 27 is constituted of an electrical insulating material. When the circumference of the terminal part 10 of the diode 3 is covered with the tube 27 without shrinking and the tube 27 is heated, the tube 27 is closely brought into contact with the terminal part 10 along the shape thereof because the volume of the tube 27 shrinks. By a similar way, the terminal part of a light emitting diode 4 is covered with the tube 27. Thus, since the discharge path of static electricity made to enter from a gap G and discharged to the terminal parts of the diodes 3 and 4 is cut off, the static electricity is not discharged.
