Working and Types of Touch Screen20 March 2021
A touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connected devices which can be used to replace mechanical button panels, and use liquid crystal display screens to create dynamic audio-visual effects.
Introduction to Step-up Transformer01 March 2021
A step-up transformer is a transformer that is used to raise the output voltage while retaining the current flow constant and without variance. This kind of transformer is predominantly used in power transmission and generation stations. The main and secondary windings are used in this transformer. In contrast to the secondary winding, the main winding has fewer twists.
Introduction to 6 Common Power Supply Design Circuits09 April 2022
This article will introduce 6 common power supply design circuits to you.
What is Mini LED?08 December 2020
Mini LED is defined as an LED device with a chip size between 50~200μm. The size of the Mini LED is between the small-pitch LED and Micro LED, which is the result of further refinement of the small-pitch LED. Mini LED can be used as a backlight source in products such as large-size displays, smartphones, car panels, and gaming notebooks. It can also be used as a self-luminous display with RGB three-color LED chips.
What is a Power Capacitor?20 November 2021
Power capacitors are capacitors used in power systems and electrical equipment. Any two pieces of metal conductors are separated by an insulating medium to form a capacitor. The size of the capacitor is determined by its size and the characteristics of the insulating medium between the two plates.

RGB LED: Circuit, Difference and Application25 March 2021
White LED and RGB LED are the same in essence. They both hope to achieve the effect of white light, but one is directly presented in white light, and the other is made by mixing red, green and blue light. RGB lamps are integrated with the three primary colors. In addition, there are blue LEDs with yellow phosphors, and ultraviolet LEDs with RGB phosphors. On the whole, both have their imaging principles. The colors of some LED backlight panels are particularly clear and vivid, even to the level of high-definition TVs. This situation is exactly the characteristic of RGB, which advertises the characteristics of red as red, green as green, and blue as blue. In terms of color mixing, it has more diversified characteristics.
