Kt Kingtronics Applications of Trimmer Potentiometers

2 Apr 2013

Example1: Flicker adjustment for LCD (Liquid - crystal display)
To adjust the reference voltage (VCOM) of LCD.
With inappropriate reference voltage, there will be flicker on LCD screen.
Use trimmer Potentiometers to adjust reference voltage for flicker restraining.

LCD has some flickers if the voltage is not suitable for LCD.

You can reduce the flickers when you adjust the voltage by using trimmer potentiometer.

Example2: Gain adjustment for Blu-ray, DVD, CD disc reading optical pick - up.

As record media Blu-ray, DVD and CD etc. usually be used, and we use optical pick - up for the data
reading and writing from disc. In an optical pick - up, there is a light - sensitive element to detect reflected
light from disc.And a trimmer potentiometer is used to adjust the sensitivity of this light - sensitive element.

Circuit example Playback system device (ex, DVD, CD, playback)

Example3: Sensitivity adjustment for sensor products.

There are all kinds of sensors around our life.

  • Lights turn on automatically when human be detected.
  • Smoke detector for fire preventing.
  • Parking assist system for distance from car to wall.
  • Product detection sensor in factory.

 For these sensors, trimmer Potentiometers are used for suitable sensitivity.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
