Disclosed is a domestic appliance, at least comprising an aluminum sole plate which is provided with a coating which is provided by means of a sol-gel process and wherein an intermediate layer is present between the aluminum sole plate and the sol-gel coating. The intermediate layer comprises a multi-layer structure.Also described is a method of manufacturing such a domestic appliance. The method comprises the steps of providing an aluminum substrate, applying a porous intermediate layer of aluminum oxide by electrochemical treatment of the aluminum sole plate in an electrolyte comprising a solution of phosphoric acid, applying a dense intermediate layer of aluminum oxide by electrochemical treatment in an electrolyte, and providing a sol-gel coating on the treated substrate.
摘要:
An LCD having the liquid crystal in at least a portion of the interpixel region displaced by a spacer material. The spacer material has a low dielectric constant relative to the liquid crystal, thus further impeding the formation of a bend deformation in the liquid crystal in the interpixel region when pixels on opposite sides of the spacer material are operating in the inversion mode. This elimination of the bend deformation in the interpixel region eliminates the reverse tilt disclination.

The invention provides optical modulation devices and displays of the DHFLCtype having a high contrast. Said modulation devices comprise a first substrate and a second substrate which are positioned substantially parallel to each other and which are provided, on their facing surfaces, with, in succession, an electrode layer and an orientation layer. This advantageous effect is achieved by using different orientation layers, the surfaced energy of the orientation layer of the first substrate being different from the surface energy of the orientation layer of the second substrate, said difference in surface energy being at least 5 mN/m. The orientation layer having the high surface energy is preferably made from rubbed polyimide, and the orientation layer having the low surface energy is preferably made from unrubbed polyorganosilsesquioxane. The optically active layer of the modulation devices in accordance with the invention exhibits a "tilted-bookshelf" structure.
摘要:
An appearance-modifying device (10; 30), for modifying the visual appearance of a surface covered thereby, comprising: first (11) and second (12) oppositely arranged optically transparent substrates; a spacer structure (13; 32) spacing apart en the first (11) and second (12) substrates in such a way that a space between the first (11) and second (12) substrates is divided into a plurality of cells (15, 16; 31a-c). The appearance-modifying device further has, in each cell (15, 16; 31a-c), an optically transparent fluid (19) having a plurality of particles (20) dispersed therein, the particles being moveable in the fluid (19) through application of an electric field; and first (17a, 18a; 33) and second (17b, 18b; 32) electrodes arranged to simultaneously, by application of a voltage across the electrodes, control a distribution of the particles (20) within each of a plurality of the cells (15, 16; 31a-c) from a first, dispersed state in which an appearance of the surface covered by the appearance-modifying device is determined by optical properties of the particles (20), to a second state in which the particles (20) are concentrated adjacent to at least one of the first (17a, 18a; 33) and second (17b, 18b; 32) electrodes in such a way that the appearance-modifying device (10; 30) becomes optically transparent.
