LED electronic display screen is an electronic display, which is combined with computer technology, information processing technology, electronic technology, phonology, chromatics and other high and new technologies. The LED display screen can be divided into monochrome screen, double color screen and full color display. As the name implies, the monochrome screen is composed of a single color of LED (see figure 1). A pixel display which is in the red and green LED is called double color screen or color screen (see figure 2). And a pixel display consists of the red, green and blue LED is called the tri color screen or full color screen(see figure 3).(more)

NTC thermistor can be applied in many fields, such as temperature measurement and control, temperature compensation, surge current suppression, environmental measurement, etc.(more)

A glass sealed NTC thermistor is a high reliability and sensitive device, based on the technology of glass sealed diodes. It has high mechanical strength and also can prevent the performance drift caused by sensitive chips exposed to the atmosphere and the physical and chemical adsorption. While the glass is relatively high, it can be good for overcurrent protection and temperature compensation of NTC thermistors.(more)

Semiconductor laser is also known as laser diode, which uses semiconductor materials as laser’s operation materials. When comparing with other lasers, laser diode has incomparable performances, such as low driving voltage, high efficiency and safe incentive mode, so that it can be widely used for long-distance communication, digital signal storage and recovery, laser range holographic application, etc. Semiconductor laser has strict demands on working conditions and it is much affected by the operating temperature and the driving current.(more)

As a fourth-generation automobile light source, LED (Light Emitting Diode) lamps have been widely used for producing many beautiful car style by car manufacturers. LED light has many advantages including no delay, energy saving, long life, low heat, seismic resistance and high color purity and it has taken place of tungsten filament lamps and halogen lamps in many fields. Although its cost is very high, LED lamp has incomparable advantages of good quality and high grade when comparing with incandescent lamp. Because of the monochromaticity of LED light, it can directly select LED components of different wavelengths to design cornering lights, brake lights, backing lights, bicycle taillight and other lights. It can also make light transmittance increase without color filters and improve the utilization rate of the light.(more)

In 1821, Thomas Seebeck discovered when two conductors with different materials and different temperature are connected, there is current flowing in the loop However, twelve years later, J. C. Peltier discovered an opposite phenomenon, that is ,by deleting a conductor in the loop, the external current can flow through the loop, and then a temperature difference between two connecting points is appeared. This phenomenon came to be known as Peltier Effect. Owing to the limitation of material at that time, the temperature difference in Petier Effect is mostly the thermal resistance produced when large current flows through the materail. Along with the development of material science in recent years, the heating or cooling effect of the connection point becomes more practical, which can be used as heat pumps. In actual application, there's no much difference with the cooling method that is based on fluorine carbon vapor compression refrigeration. There are no moving parts and working fluid in TEC, so it makes refrigeration equipment miniaturization possible.(more)

TEG is the abbreviation of thermoelectric generator, which can convert heat directly into electricity, totally opposite to TEC. TEG can be used as anti-corrosion protection for oil pipeline and gas pipeline and it can also be used as a power supply for monitoring facilities.(more)

The ATH100KL2A is a capped ntc thermistor encapsulated with glass and packaged in a compact ring lug. This thermistor series consist of ATH100KL2A, ATH100KL2AT63 and ATH100KL2AT63S. The ATH100KL2A has two leads coated with copper, the ATH100KL2AT63S has the two leads covered with plastic tubing and sealed by epoxy for insulation and liquid resistant, while the ATH100KL2AT63 is the non-sealed version. ATH100KL2A series thermistors feature better long term stability, higher reliability and wider temperature range when compared with conventional thermistor assemblies containing epoxy encapsulated thermistors inside.(more)

The ATH10KL2C is a thermistor assembly with a ring lug outside the glass encapsulated ntc thermistor. The ATH10KL2C series thermistor consists of three types, ATH10KL2C, ATH10KL2CT70 and ATH10KL2CT70S. The ATH10KL2C comes with two leads coated with copper, the ATH10KL2CT70 has the copper leads with high temperature plastic tubing and also sealed by epoxy, while the ATH10KL2CT70S is the sealed version of ATH10KL2CT70. The different types are applied to different applications. The sealed version is liquid resistant, so it can be used in the applications with some noncorrosive liquid.(more)
