Abstract: Provided are an interactive handwriting display device and an interactive handwriting capture device. The interactive handwriting display device has a display panel and a patterned band-pass filter component, and the patterned band-pass filter component has a substrate and multiple band-pass filter units. The interactive handwriting capture device includes an optical signal selector, an image-forming module, a photodetector chip and a microprocessor. By using the interactive handwriting display device with a patterned filtering function and the interactive handwriting capture device with the recognition function, the addressable ITO sensor's need of electrical connection is eliminated, providing interactive operating function and the writing function of high sensitivity and accuracy. Also, the manufacturing complexities are reduced and the integration of components is improved as the touch screens get larger in size.
