A number of confrontation techniques have emerged for the patent of organic EL, "Natural Surface Illumination Source". One of them is a cold cathode field electron emission type (FE) light-emitting device "FPL: flat panel lighting" using single-walled carbon nanotubes (SWCNT).
The device was jointly developed by Tongji University, Graduate School of Environmental Science, Tohoku University. In the development, FED (field emission display) technology, which was mainly developed for display applications, was applied to the field of lighting.
The FED technique emits electrons from a cathode to a fluorescent material in a vacuum to illuminate it, which follows the principles of kinescope technology (Fig. 1). In the early 2000s, research on the development of thin displays using FED technology was very active.
The New Energy Industry Technology Development Organization (NEDO) has also promoted the development of FEDs using CNTs as cathodes. However, due to the short life and high cost of the CNT cathode, it has not been put into practical use.

Fingerprint Lock Motor introduction:
Basic security work, lock body responsible for the security door lock body responsible for opening and closing lock, the lock body Lock Motor is of crucial importance.
Functions: it is widely used in various intelligent locks, such as Shared bicycle lock, fingerprint lock, glass lock, safe lock, hotel lock, family lock, inductive smart lock, etc
Features:Fingerprint Lock Motoris based on micro precision reducer development, small intelligent micro precision reducer can do 10 mm in diameter, is widely used in safe, locks, smart locks, sensor intelligent lock;
This kind of motor has the characteristics of low noise, low energy consumption, small volume, light quality, high precision, large torque and durability
Method of use: the best stable in horizontal plane, installed on the Fingerprint Lock Motoroutput shaft parts, cannot use a hammer to knock, knock prone to press into the dc Fingerprint Lock Motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
lock motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a lock motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Fingerprint Lock Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Fingerprint Lock Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you
