8. The driving method of claim 1 , wherein the second electrode is a non-transparent conductive layer.
9. The driving method of claim 1 , further comprising:
generating the control signal based on a user- or system-inputted light-shielding-zone operating signal.
10. The driving method of claim 9 , wherein
the display apparatus further comprises a light-shielding-zone signal control module, and
the control signal is outputted by the light-shielding-zone signal control module upon receiving the user- or system-inputted light-shielding-zone operating signal.
11. A display apparatus, comprising:
a display zone,
a light-shielding zone disposed adjacent to at least one side of the display zone, the light-shielding zone comprising an electrically controlled material having a controllable light shielding rate,
a control circuit for controlling the light shielding rate of said electrically controlled material in the light-shielding zone to shield light in accordance with a control signal;
a first electrode in both the display zone and the light-shielding zone;
a second electrode in at least the display zone; and
said electrically controlled material between said first and second electrodes in the display zone for displaying images in accordance with an image control signal;
wherein the control circuit is configured to control the light shielding rate of said electrically controlled material in the light-shielding zone to be higher than in the display zone when the display zone is displaying the images.
12. The display apparatus of claim 11 , wherein the light-shielding zone is disposed around the display zone.
13. The display apparatus of claim 11 , wherein said electrically controlled material is a liquid crystal layer.
14. The display apparatus of claim 11 , wherein said control signal is generated in accordance with the image control signal.
