摘要:
Two-sided, back-to-back displays are formed by sealing the backplates of two displays against one another. Mechanical parameters of the backplates, e.g., stiffness and strength, do not meet the requirements for standalone one-sided displays which are otherwise similar to the two displays. However, when sealed against one another, the backplates reinforce each other to meet or exceed the requirements for both one-sided and two-sided displays. The presence of backplates on each of the constituent one-sided displays allows one or both of those displays to be individually tested, thereby increasing the production yield of the back-to-back displays. The display elements of the displays can comprise interferometric modulators.

A light modulator is arranged as an array of rows and columns of interferometric display elements. Each element is divided into sub-rows of sub-elements. Array connection lines transmit operating signals to the display elements, with one connection line corresponding to one row of display elements in the array. Sub-array connection lines electrically connect to each array connection line. Switches transmit the operating signals from each array connection line to the sub-rows to effect gray scale modulation.

An interferometric modulator array is integrated with collapsible cavity MEMS electrical switches. The electrical switches may have similar physical geometry as the display elements. The switches may form row or column select functions for the display.
摘要:
An interferometric modulator array device with backlighting is disclosed. The interferometric modulator array device comprises a plurality of interferometric modulator elements, wherein each of the interferometric modulator elements comprises an optical cavity. The interferometric modulator array includes an optical aperture region, and at least one reflecting element is positioned so as to receive light passing through the optical aperture region and reflect at least a portion of the received light to the cavities of the interferometric modulator elements. In some embodiments, the interferometric modulator elements may be separated from each other such that an optical aperture region is formed between adjacent interferometric modulator elements.

An interferometric modulator is provided having a faster deformation time constant on actuation than relaxation time constant upon release from actuation. In some embodiments, apertures are formed in a mechanical membrane to decrease pressure, including liquid and/or gas pressures, on the membrane when actuated. In other embodiments, a dampening layer is disposed in close proximity above the membrane to apply greater downward pressure on the membrane and therefore slow the motion of the membrane when released from an actuated state. Other embodiments comprise structures, such as a heating element or vacuum device, to manipulate pressures above and/or below the mechanical membrane to affect the mechanical persistence of the display device.

An interferometric light modulating device having two viewing surfaces is provided. In some embodiments, the device can generate two distinct images, one on each side of the device, simultaneously.
摘要:
A display panel includes an array of interferometric modulators arranged over a transparent substrate and a transparent electrical device arranged between the array of interferometric modulators and the transparent substrate. The transparent electrical device may be electrically connected to the array of interferometric modulators or to other parts of the display panel. Examples of suitable transparent electrical devices include capacitors, resistors, inductors and filters. The use of such transparent electrical devices may provide various advantages, such as increased design flexibility, by allowing the electrical devices to be included in various parts of the array, including the viewing regions.
