1. An organic light emitting device comprising:
an anode;
a cathode; and
a plurality of organic layers interposed between the anode and the cathode,
wherein the plurality of organic layers includes a first layer which is an emission layer, a second layer which is in contact with the emission layer on an anode-side of the emission layer, and a third layer which is in contact with the emission layer on a cathode-side of the emission layer,
wherein the first layer includes a host material, a light emitting material, and another material,
wherein the host material and the light emitting material have an ionization potential larger than an ionization potential of a material of the second layer,
wherein the LUMO of the another material is smaller than the LUMO of a material of the third layer,
wherein the light emitting material has a band gap smaller than both band gaps of the host material and the another material,
wherein the LUMO of the another material is smaller than the LUMO of the host material, and the LUMO of the host material is smaller than the LUMO of the material of the third layer,
wherein the first layer includes a different light emitting material from the light emitting material,
wherein the another material has an ionization potential smaller than an ionization potential of at least one of the light emitting material and the different light emitting material from the light emitting material, and
wherein the organic light emitting device emits a white color.
2. An apparatus comprising a substrate, the organic light emitting device according to claim 1 and a color filter,
wherein the substrate has the organic light emitting device thereon.
3. An apparatus comprising a substrate and the organic light emitting device according to claim 1,
wherein the substrate has the organic light emitting device thereon, and the apparatus has a top emission structure.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A diskectomy instrument comprising:
a) an elongate body having a distal end and a proximal end, the elongate body having a blade opening proximate the distal end;
b) a blade movably mounted at least partially within the elongate body proximate the blade opening, the blade having a distal end, a proximal end, at least one sharp edge extending at least partially between the distal end and the proximal end, a ramped portion and a stem mating portion; and
c) a drive stem movably mounted within the elongate body having a distal end, a proximal end and a blade mating portion, the drive stem being configured to slidably engage the blade when the drive stem is moved distally thereby extending the blade radially outward through the blade opening and extending the at least one sharp edge toward a radial cutting direction of the diskectomy instrument relative to a longitudinal axis of the diskectomy instrument and the blade mating portion being configured to cooperatively engage the stem mating portion of the blade when the drive stem is moved proximally thereby retracting the blade.
2. The diskectomy instrument of claim 1, further comprising an actuator coupled to the proximal end of the drive stem to effectuate proximal and distal movement of the drive stem linearly within the elongate body.
3. The diskectomy instrument of claim 2, wherein the actuator is a positioner configured so that operating the positioner in a first direction causes the drive stem to move distally and operating the positioner in a second direction causes the drive stem to move proximally.
4. The diskectomy instrument of claim 3, wherein the positioner includes incremental indication marks which generally correspond to the radial position of the blade relative to the elongate body.
5. The diskectomy instrument of claim 2, further comprising a positioner to the actuator wherein operating the positioner in a first direction causes the drive stem to move distally and operating the positioner in a second direction causes the drive stem to move proximally.
6. The diskectomy instrument of claim 5, wherein the positioner includes incremental indication marks which generally correspond to the radial position of the blade relative to the elongate body.
7. The diskectomy instrument of claim 2, further comprising a blade rotation control mechanism coupled to the blade wherein operating the blade rotation control mechanism causes the at least one blade to rotate in a cutting direction.
8. The diskectomy instrument of claim 1, wherein the diskectomy instrument is disposable.
