The light emitter (10) has such a low beam divergence that the feedover from the light emitter (10) to the light receiver (11) is kept below a predetermined value.
One finger is provided with an array of light emitters (31e) and the other is provided with an array of light receptors (31r), each of the light emitters being coupled, on a one-to-one basis, with each of the light receptors.
The light source (23') may be an emissive display such as an electroluminescent or thin film electroluminescent display.
Alternatively, the light source (23') may be a flat panel display such an emissive display or an electroluminescent display.
An alternating current-driven LED light emitting device comprises the LED light emitting unit.
The light capturing aid is a fibre optic face plate located between the light emitting material and the detector, but not in contact with the light emitting material.
The light-emitting element according to this invention easily enables a two-dimensional arrangement and highly-advanced integration.
In a light-emitting module (40), an electrode pattern which is supplied with current for emitting light is formed on the light-emitting surface (48a) of a semiconductor light-emitting device (48).
A process for fabricating an organic light-emitting device ('OLED') (100).
The red light-emitting layer (11) contains a hole-transporting light-emitting material and has a hole transporting ability.
The light-emitting device emits the visible light as output light.
A light emitting diode (LED) and a manufacturing method thereof, and a lighting emitting device are provided.
A microlens array (100) for a light emitting device is disclosed.
A sealing structure (190) for an organic light emitting device display (100).
Specifically disclosed is a substrate (10) for a light emitting element (30), which is composed of a spinel.
This light-emitting element is capable of being oscillated continuously with ease at room temperature.
To increase the lifespan of the lamp, a protective coating is provided on the layer of light-emitting material.
The protective coating comprises a material that is transparent to both ultra-violet and visible light, yet is capable of filling even small gaps in the light-emitting material.
The light emitting device includes a plurality of OLED's (20), each having a minimum planar dimension.
