Image display/input apparatus |
摘要 |
A backlight emits diffused light beams. An emission direction characteristic-forming plate allows light beams which have been incident thereon at generally right angles therewith to pass therethrough and intercepts light beams which have been incident thereon obliquely. An image display/input panel has light receiving elements each incorporated in a corresponding pixel having a liquid crystal cell. In an image input operation, pixels are sequentially turned on and off so as to scan an original document by parallel light emitted vertically from a turned-on pixel. Light reflected by the original document is received by the light receiving element incorporated in the turned-on pixel and converted into an electric signal. Light emitted from the turned-on pixel of the image display/input panel and reflected by the original document is received by only the turned-on pixel. In this manner, a high resolution can be obtained in the image input operation.
