Abstract
A digital X-ray detecting panel includes a wavelength transforming layer and a photoelectric detecting plate. The wavelength transforming layer is configured for transforming X-ray into visible light. The photoelectric detecting plate is disposed under the wavelength transforming layer. The photoelectric detecting plate includes a substrate and a number of photoelectric detecting units disposed on the substrate and arranged in an array. Each of the photoelectric detecting units includes a thin film transistor and a photodiode electrically connected to the thin film transistor. The thin film transistor has an oxide semiconductor layer. The digital X-ray detecting panel can avoid a photocurrent in the thin film transistor, and thereby improving detecting accuracy of the digital X-ray detecting panel. A method for manufacturing the digital X-ray detecting panel is also provided.
