Image display apparatus and image display module |
摘要 |
An image display apparatus configured by a display panel having an image memory element in a pixel, which achieves low power consumption. A nonvolatile image memory element 1, which can change the resistance value by phase change, is connected to a pixel electrode 25 of a liquid crystal element 5. The output of a thin-film transistor 17 driven by scanning and signal electrode lines 7, 9 is connected to the pixel electrode 25. When the scanning electrode line 7 is selected to have a high level voltage, the thin-film transistor 17 is turned on and a current signal flowing through the signal electrode 9 is sent through the image memory element 1 to a reference electrode line 15. Depending on the current value or pulse width passing through the image memory element 1, the resistance of the image memory element 1 is changed and is stored as a resistance value. A liquid crystal drive voltage to be applied to the liquid crystal element 5 is varied depending on the resistance of the image memory element 1 and an image is displayed on the liquid crystal element 5.
