摘要:
57 A method of making a multicoloured member comprising providing a surface of the member with material which cannot normally be dyed, treating the material so that it is rendered capable of being dyed, dyeing the material a predetermined colour and subjecting the dyed material to a further treatment which prevents further dyeing thereof, characterised in that a portion only of the said material is so treated, dyed a predetermined colour and subjected to the further treatment, at least one further portion of the material being subsequently so treated, dyed a different colour, and subjected to the further treatment.
摘要:
Acolour liquid crystal display device comprises a first display cell (A) which has an optical shutter effect disposed on a second twisted nematic liquid crystal display cell (B) which has a double layered multi-colour polarizing plate (8) in which the absorption axes of respective layers having different absorption wavelength regions are perpendicular to each other, picture elements of the first display cell (A) and the second display cell (B) being arranged so as to correspond to each other.
摘要:
A multi-colour display device comprises a first substrate (1), a second substrate (5) spaced from the first substrate (1), a display material (7) disposed between the first substrate (1) and the second substrate (5) and a plurality of display electrodes (2) provided on an inner surface of the first substrate (1). A counter electrode (4) is provided on an inner surface of the second substrate (5) and a plurality of different colour filters (3) are disposed on the display electrodes (2). The colour filters (3) contain electro-conductive particles whereby a drive voltage fed to the display electrodes (2) is applied via the colour filters (3) to the display material (7) substantially without voltage drop.
摘要:
A method of manufacturing a plurality of coloured members (M) comprising forming at least one conductive film layer (3, 3') on a substrate (1) of insulating material; forming a coloured layer (4) on the or each conductive layer (3, 3') by electrodepositing colouring material and a polymer on the or each conductive layer (3, 3'); and cutting or otherwise dividing the substrate (1) having the coloured layer or layers (4) thereon so as to form a plurality of members (M) each of which has at least one said coloured layer (4) thereon.

摘要:
A method of manufacturing a multicolour filter comprises the steps of forming electroconductive layers (7) electrically insulated from one another on a substrate (6) and forming different coloured layers on different electroconductive layers by electro-depositing a polymer (8). The colouring material may either be deposited with the polymer or after the polymer has been deposited can be dyed.
