Abstract
A display device comprising: a light switching unit comprising an array of pixels each operable to vary the transmission of light therethrough; and a backlight comprising a first series of regions of organic light-emissive material having a first emission color and a second series of regions of organic light-emissive material having a second emission color, each region of organic material being located so as to lie behind a plurality of pixels of the array in the viewing direction for backlighting those pixels; and at least one of the regions of organic light-emissive material being formed by a process of ink-jet deposition.
Claims8
A method of forming a light-emissive unit of a display device comprising:
- providing a first electrode;
- depositing an organic light emissive layer over the first electrode, wherein:
- the organic light emissive layer comprises a small molecule emissive material,
- the organic light emissive layer is a patterned layer deposited by solution processing;
- and
- depositing a second electrode over the organic light emissive layer.
