Embodiment Construction

[0035] An induction panel according to an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a sectional view of main parts of an embodiment of the present invention. figure 2 It is a schematic diagram explaining the manufacturing method of this invention.

[0036] First of all, regarding the induction plate of an embodiment of the present invention, as figure 1 As shown, a lower electrode plate 1 made of a transparent resin material such as acrylic or polycarbonate is arranged at the lowermost part.

[0037] The outer shape of the lower electrode plate 1 is formed into a substantially rectangular shape by forming processing or the like, and the thickness thereof is 0.5 to 1 mm.

[0038] In addition, a lower transparent conductive film 3 made of a transparent ITO (Indiun Tin Oxide) resistive film is formed on one surface of the lower electrode plate 1 through a transparent thin film 2 having a thickness of 40 to 100 μm by ...

Abstract

The present invention provides a sensing board with a high productivity capable of continuously forming a lower conductive film on the lower electrode plate by pre-forming a lower conductive film on a sheet film and integrating the sheet film and lower electrode plate when the lower electrode plate is processed and formed. The inventive sensing board includes: a lower electrode plate and an upper electrode plate opposite to each other with a predefined gap; an a lower conductive film and an upper conductive film arranged respectively on the opposite surfaces of the lower electrode plate and upper electrode plate. The lower electrode plate forms a lower conductive film on a surface opposite to the upper electrode plate via a film having a predefined thickness. The film has one surface formed thereon the lower conductive film and the other surface adhered thereon the lower electrode plate in a forming process thereby providing an integration.

Description

technical field [0001] The present invention relates to an induction panel and a manufacturing method thereof, in particular to an induction panel installed on a display surface of a liquid crystal display device, etc., which can be input with coordinates such as a pen or a finger according to the display content of the display surface, and a manufacturing method thereof. Background technique [0002] In recent years, sensor pads as coordinate input devices have been widely used in mobile devices such as electronic notebooks and portable information terminals. [0003] The sensor board used in these mobile devices, for example, is mounted on the display surface side of a liquid crystal display device, and various functions such as calendar, schedule, and address book management can be displayed on the display surface visible through the sensor board. switch. [0004] Alternatively, desired characters, images, etc. can be input by moving the operation surface made of a film-...
