Problems solved by technology

[0006] The mechanism for sliding the tactile panel relative to the display panel according to the inclination of the display panel relative to the device body as suggested in Japanese Laid-Open Patent No. 3-48318 would be so complicated that it would prove to increase the overall size of the device, resulting in cost increase
[0007] The connection mechanism for connecting the touch panel to the LCD panel as proposed in Japanese Laid-Open Patent No. 10-207632 may increase the overall size of the device, resulting in an increase in the manufacturing cost of the device
[0008] In addition, the connection mechanism cannot tilt the touch panel and LCD panel beyond a certain extreme angle
[0009] Also, both devices use a mechanical joint between the tactile panel and the display panel, so there is a common problem that any displacement is not conclusively compensated, even when the displacement does not need to be compensated

Embodiment Construction

[0022] figure 1 is a schematic perspective view of a touch panel input type electronic device according to an embodiment of the present invention. Such a touch panel input type electronic device can be applied to various electronic equipment, for example, an electronic cash register, a word processor, a portable information terminal, and the like. Such as figure 1 As shown, this electronic device is composed of a flat box-shaped main body 10 and a flat-shaped coordinate touch input and display unit 20 . The unit 20 is arranged to cover the upper surface of half of the longitudinal portion of the body.

[0023] The coordinate touch input display unit 20 is sized to cover substantially half of the longitudinal portion of the main body 10 . The other half has a (trapezoidal) cut-out end disposed transversely in substantially the longitudinal center of the main body 10 . The rotation axis 21 of the coordinate touch input display unit 20 is disposed along the lateral end of the...

Abstract

A displacement between an input point on a touch-sensitive panel and a display point on a display panel must be reliably corrected by a simple, inexpensive structure. A transparent touch-sensitive panel having a coordinate system formed on its surface for locating the position of a point input and a LCD panel having a coordinate system for locating the position of a display point corresponding to the input point on the touch-sensitive panel are laminated together and swingably attached to a main body. A rotation angle of the touch-sensitive panel and the LCD panel with respect to the main,body is detected by an angle detector. The abscissa and ordinate values of an input point in the coordinate system of the touch-sensitive panel are corrected according to a rotation angle detected by the angle detector and a distance between the surfaces of two panels and displayed in the display coordinate system of the LCD panel.

Description

technical field [0001] The present invention relates to a touch panel input type electronic device. The device has a touchpad and a display panel. A touchpad is a touch-sensitive pad with a point input coordinate system formed on its surface. The display panel is used to display coordinate data of points corresponding to points input to the touch-sensitive panel. The touchpad and display panel are layered together. Background technique [0002] Coordinate touch input and display devices consisting of an LCD display panel on which a touch-sensitive panel made of a resistive film is laminated are widely used in various electronic equipment such as electronic cash registers, word processors, portable information terminals, etc. . Since the point input coordinate system formed on the input touch panel matches the display side coordinate system formed on the front surface of the LCD display device, this coordinate touch input and display system can display the touch point inp...
