摘要： A touch panel is constructed of a top sheet member (110) having a resistive membrane on its inner surface and a base sheet member (130) having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers (160) being located in between. The top sheet member is formed by laminating a bulge-resistant film (101), a polarizing plate (102), a quarter wavelength plate (103), and a light isotropic film (104) in this order from above. A PET film which is not heat-treated so as to have a higher thermal contraction rate than the other members of the top sheet member underneath such as the polarizing plate, is used as the bulge-resistant film (101). Since the bulge-resistant film contracts more than the polarizing plate under a high ambient temperature, after the ambient temperature returns to normal, the bulge-resistant film does not become slack against the polarizing plate. Accordingly, the top sheet member can be kept from bulging outward.

摘要： A method and apparatus for discriminating against false touches in a touchscreen system is provided. The system is designed to confirm a touch registered by one touch sensor with another touch sensor, preferably of a different sensor type, prior to acting upon the touch (i.e., sending touch coordinates to the operating system). If the touch registered by the first touch sensor is not confirmed by the second touch sensor, the touch is invalidated. Thus the strengths of one type of sensor are used to overcome the deficiencies of another type of sensor. In one aspect, the secondary touch sensor comprises a force sensor to discriminate between true and false touches on other types of touch sensors, such as contaminants on optical and surface acoustic wave sensors, noise or weak signals on capacitive sensors, etc. The force sensor may be a simple one-element system that merely indicates that a touch has occurred or a multi-element system that can provide confirming or supplementary coordinate data. In another aspect, a capacitive sensor is used to confirm or veto touch data from optical, surface acoustic wave, and force sensors. As is the case with the secondary force sensor, a secondary capacitive sensor may be a simple discrete type or capable of providing touch coordinates in its own right. In a specific embodiment, one in which no touch overlay is used on a CRT monitor, the secondary touch sensor may employ the resistive coating on the surface of the CRT in combination with a current monitoring circuit that measures the amplitude of the electromagnetic noise signal coupled to the resistive coating. In this application when the screen is touched by a grounded object, the detected signal amplitude change exceeds a preset threshold thus indicating a valid touch.

摘要： A general method is described for producing an inexpensive touchscreen system that provides accurate positional information and compensates for manufacturing variations without complicated sensor arrangements. Utilizing a set of sensed signals (160) that are unique to each location on the touchscreen sensor, equations for X and Y (162) are derived via curve fitting methods. The coefficients (163) of the equations are stored with the sensor. During touchscreen operation the coefficients are used to calculate X and Y (164) to the desired accuracy directly and independently.

摘要： An input device is enabled to distinguish between a pen-tap or pen-write action (i.e. a point contact) and a pen-erase action, associated with the use of a soft and wide surface which is generally represented by an area contact. The behaviour of a touch panel in response to each type of contact is different, and the method, in making use of these different responses, is able to distinguish between a point contact and an area contact, thereby distinguishing between a pen-tap action and a pen-erase action respectively.
