Abstract: A flexible display (200) includes a display effect layer (128) formed on a back plane substrate (114) configured and dimensioned to be flexible. A front plane substrate (121) is configured and dimensioned to be flexible and is mounted on the display effect layer. The front plane substrate has a color filter (124) formed thereon such that aperture and parallax effects are controlled due to proximity between the display effect layer and the color filter. Methods for fabricating flexible displays are also disclosed.

Abstract: A gray level compensation mechanism is proposed for flexible displays. Flexible displays exhibit cell gap variations upon bending. The cell gap is measured during operation of the display (capacitive, piezoelectric). The pixel voltage is adjusted according to the measured cell gap. This results in a gray level that is independent of the local bending radius.

Abstract: A thin film transistor circuit has a main thin film transistor (10), a control input (12) for controlling the operation of the main thin film transistor and a threshold adjustment capacitor (14) connected between the control input and the gate of the main thin film transistor. A charging circuit (16, 18) is used for charging the threshold adjustment capacitor to a desired threshold adjustment voltage. The circuit is used to affect a voltage shift to the voltage applied to the control input. This effectively implements a threshold voltage change by altering the relative voltages on the main transistor gate and the control input.

Abstract: A rollable display (101) is wearable on a sleeve (103). The display (101) is part of a wrist-based device with a “U” shape. A part of the device is on top of the sleeve (103). The display (101) can be rolled out for use as needed. The device itself may be flexible or bendable i.e. have a x-rigid, U-shape or may allow the “U” shape to be folded out, for example by a hinge or sequence of connected segments that can be rotated freely, but which keep their position after being moved. The display (101) may be rolled out from under the sleeve (103) and then over the sleeve (103) along a predefined curve by means of a guiding mechanism. The device is easy to use, allows the use of large displays that may always be visible and allows freedom in the display design with respect to the direction in which the flexible display (101) is rolled out.

Abstract: A conformable, flexible or roll up display (100) includes a matrix display layer (115) including lines of sub-pixels (116). Each line has an associated color assigned to the line (132, 134, 136), and each line extends along a roll up or bend direction (140). A display effect layer (128) is formed on the matrix layer. A color filter layer (152) includes striped color filters (154) which extend in the roll up or bend direction. The striped color filters each include a filter color corresponding with the lines of sub-pixels in the matrix layer to address misalignment and color errors due to bending or rolling up the display. Methods for fabricating flexible displays are also disclosed.
