1, LED backlight development to ultra-thin
(1) LED thinning, high power and thinner light guide plate
According to market research firm DisplaySearch, global LED LCD TV sales in 2009 were about 4.09 million units, accounting for only 3% of the entire flat-panel TV market, but sales will soar to more than 123 million units in 2014, accounting for the entire flat-panel TV market. The share also soared to 53%.
LED color TV is not a new display technology in nature, but it replaces the traditional cold cathode fluorescent lamp with a new LED light source technology. However, this kind of LCD TV with side-mounted LED backlight has a slim body that is difficult to compare with traditional products: most of the LED TVs produced by famous manufacturers are about 2cm in thickness, which is unmatched by traditional LCD TVs. of.
LED TVs mainly compete for not only thickness, but also more economical, energy-saving power consumption, and better image quality. The technical performance advantages of many aspects are the core reasons for the rapid growth of the LED TV market.
(2) No borders
Although LCD TVs can't really achieve "no borders" - this is just an exaggerated description of the ultra-narrow bezel. However, industry experts have predicted that the borderless products will become another peak in the design of LCD TVs after LED ultra-thin.
In fact, as early as three years ago, many LCD companies, including Samsung, have invested in the development of ultra-narrow bezel products. However, these technologies are mainly used in engineering display fields, such as LCD TV splicing walls. In April of this year, Samsung's LCD screen wall product launched in the domestic market has a narrowest frame thickness of less than 3mm. Since then, companies such as Sharp, LG, and Taiwan have also introduced liquid crystal display panels that can meet the thickness of the millimeter frame. For the whole machine enterprise to choose. The support of many upstream manufacturers, on the one hand, illustrates the practical value of borderless technology, on the other hand, it shows that the technical bottleneck of LCD TVs that make millimeter-level or even smaller-level frames has been basically broken.
2, LED backlights in line with the market green, environmental protection concept
At this stage, large-size TV backlights are mainly based on direct-type. Now EU standards, domestic standards, products must comply with RoHS standards, UL standards, and later added halogen-free requirements. The CCFL products that are used in large quantities now contain Hg substances in the lamps. Due to this characteristic, the exemption of the substance is added to the standard, that is, the substance is qualified and available in a certain amount. However, the substances containing Hg in CCFL are still contrary to the current environmental protection requirements. The current products require green and environmental protection. The notebook computers in the product backlights have no Hg requirements for backlight products from the use of LEDs. The emergence of large-size LED backlights is in line with the current market requirements for green and environmental protection.
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
