Abstract

An electro-optically active display device including at least one individually addressable pixel, each pixel being provided with an obstructing element, such as a reservoir light shield, a black matrix or a mirror element. A portion of at least one electrical component is positioned beneath the obstructing element in such a way that the portion is not visible for a viewer of the display device.

Claims (19)

1. Electro-optically active display device with physical transport of the electro-optically active medium through the device, comprising at least one individually addressable pixel, each pixel being provided with an obstructing element, wherein a portion of at least one component, being one of an electrical component other than an electrode and electrode driving lines, is positioned beneath the obstructing element in such a way that the portion is not visible for a viewer of the display device.

2. The display device according to claim 1 , wherein said at least one component is one of a storage capacitor, a sensor or a thin film transistor.

3. The display device according to claim 1 , wherein said display is a reservoir electrophoretic display device, comprising a reservoir light shield, beneath which one or more of an electrode, a storage capacitor, a sensor, and a thin film transistor is positioned.

4. The display device according to claim 3 , said pixel further comprising a reflective element for enabling transflective operation, whereby a portion of an additional component is positioned beneath the reflective element, in such a way that the portion of the additional component is not visible for a viewer of the display device.

5. The display device according to claim 1 , wherein said display is one of an electrophoretic display, an electro-wetting display or an electro-mechanical display.

6. The display device according to claim 1 , wherein a portion of a mechanical component is positioned beneath the obstructing element in such a way that the portion of the mechanical component is not visible for a viewer of the display device.

7. The display device according to claim 6 , wherein the mechanical component is at least one of a spacer and a barrier.

8. The display device according to claim 1 , wherein the obstructing element is arranged behind a front substrate.

9. The display device according to claim 1 , wherein a portion of a spacer is positioned beneath the obstructing element.

10. The display device according to claim 1 , wherein a portion of each of at least two electrical components are positioned beneath the obstructing element.

11. The display device according to claim 1 , wherein a portion of at least one of a gate line and an electrode is positioned beneath the obstructing element.

12. The display device according to claim 1 , wherein the at least one component is arranged perpendicular to a viewing direction.

13. The display device according to claim 1 , wherein the obstructing element is one of a reservoir light shield, a black matrix and a reflecting element.

14. A reservoir electrophoretic display device, comprising at least one individually addressable pixel, said pixel having a reservoir light shield, said pixel further comprising a reflective element for enabling transflective operation, wherein at least a portion of an electrical component is positioned beneath the reflective element in such a way that the portion is not visible for a viewer of the display device.

15. The display device according to claim 14 , wherein the electrical component is one or more of an electrode, a storage capacitor, a sensor, a source line and a thin film transistor.

16. The display device according to claim 14 , wherein at least a portion of a mechanical component is positioned beneath the reflective element in such a way that the portion of the mechanical component is not visible for a viewer of the display device.

17. The display device according to claim 14 , wherein a portion of at least one of an electrical or a mechanical component is positioned beneath the reservoir light shield in such a way that the portion is not visible for a viewer of the display device.

18. The display device according to claim 17 , wherein the portion of the at least one of an electrical or a mechanical component is a portion of the electrical component and wherein the electrical component is one or more of an electrode, a storage capacitor, a sensor, a source line and a thin film transistor.

19. The display device according to claim 17 , wherein the portion of the at least one of an electrical or a mechanical component is a portion of the mechanical component and wherein the mechanical component is one or more of a spacer and a barrier.
