摘要:
An electroluminescent device (1) has a relief pattern (17) comprising overhanging sections (13) for patterning an electrode layer (11) of the device (1). In order to prevent the take up and transport of fluid, from which a functional layer (7, 9) is obtainable, along the capillary channels (23) formed by the overhanging sections (13), the relief pattern (17) comprises accompanying sections (15) which are positioned at distance of the overhanging sections (13) and between the sections (13) and the electroluminescent areas (21) comprising the functional layers (7,9). A method of manufacturing the EL device (1) comprises depositing the functional layer or layers (7, 9) by means of a wet deposition method such as inkjet printing.

A display for displaying and storing images comprises an optically addressable electrophoretic display (PD) with a stack of a photoconductive layer (PCF) and an electrophoretic layer (EF) being sandwiched between electrodes (E1, E2). An optical addressing means (AD) supplies addressing light (AL) to the photoconductive layer (PCF). A controller (CO) controls a driver (DR1) to supply a drive voltage (DV) between the electrodes (E1, E2) with a value enabling a change of the optical state of the electrophoretic layer (EF) in response to the addressing light (AL) impinging on the photoconductive layer (PCF). Finally, the power consumption of the optical addressing means (AD) is minimized.
摘要:
An organic light emitting device (10) is provided which is encapsulated by a Siloxane film (17). This Siloxane film (17) is applied to the light emitting portion of the diode (10) providing for protection against contamination, degradation, oxidation and the like. The Siloxane film (17) carries an optical element, such as a lens (18) for example. This optical element (18) is arranged such that the light generated inside the diode (10) is output through it.
