    摘要: The invention discloses a light guide apparatus which comprises a light guide (1). The light guide (1) comprises a plurality of diffraction gratings (2) on a first surface of the light guide (1), wherein each diffraction grating (2) has a pre-set pitch and is configured to diffract a portion of light emitted from a corresponding light source to one side of the light guide (1). As the plurality of diffraction gratings (2) is placed on the first surface of the light guide (1) facing the light sources, the light guide apparatus is more robust to damage and fingerprints.

    摘要: An active matrix display device comprises an array of display pixels, each pixel comprising: a current-driven light emitting display element (2); a drive transistor (22) for driving a current through the display element; a storage capacitor (24) for storing a voltage to be used for addressing the drive transistor; and an addressing transistor (16) for coupling data from a data line (6) to the pixel during pixel addressing. The addressing transistor (16) comprises a phototransistor, and the data line (6) is used for external monitoring of the phototransistor. This device design uses a pixel-addressing transistor (16) as the optical feedback element. This addressing transistor is a fundamental requirement of an active matrix-addressing scheme, and its use as a feedback element can therefore avoid any addition pixel complexity to implement an optical feedback function.

    摘要: An arrangement for providing polarized light to, e.g. a LCD, is disclosed. The arrangement comprises a substrate (201) and a top layer (202). The substrate (201) is preferably optically anisotropic and the top layer (202) is either isotropic or anisotropic. The respective indices of refraction are chosen such that polarization separation occurs at the interface (214) between the substrate (201) and the top layer (202). Furthermore, the indices of refraction are chosen such that there are no restrictions on the angle of incidence (&thgr;i) of the incoming light (L), and hence obviating the need for collimation of the incoming light (L). The top layer (202) comprises light outcoupling structures, internally or externally.
