Abstract

The invention is an optical coordinate input device. The optical coordinate input device includes a frame, a first touch detection area, a second touch detection area, a first detection module, a second detection module and a processing module. The second touch detection area partially overlaps the first touch detection area. The first detection module is disposed on the frame and adjacent to the second touch detection area for detecting the first touch detection area to generate a first touch coordinate signal. The second detection module is arranged on the frame and adjacent to the first touch detection area, and is used to detect the second touch detection area to generate the second touch coordinate signal; wherein the second detection module and the first detection module are located on the frame on different planes. The processing module is used for executing a coordinate calculation program according to the first and second touch coordinate signals.

Description

technical field [0001] The invention relates to an optical coordinate input device, in particular to an optical coordinate input device which can be used for super large size. Background technique [0002] With the advancement of technology, touch panels have been widely used in daily life, enabling users to control electronic products more intuitively. In the prior art, the touch panel is usually a resistive or capacitive structure. However, resistive or capacitive touch panels are only suitable for small-sized touch panels, and if they are used for large-sized touch panels, the manufacturing cost will be greatly increased. [0003] Therefore, an optical coordinate input device has been invented in the prior art to solve the problem of high cost when using a resistive or capacitive large-size touch panel. Please refer to figure 1 A schematic diagram of an optical coordinate input device in the prior art. [0004] figure 1 The optical coordinate input device 90 includes...
