Under the new consumer wave, where is the springboard for the 7 segment LED display screen industry?
OLED is an organic LED with characteristics such as ultra-thin, ultra-light, high brightness, and high contrast. Compared to traditional LCD liquid crystal displays, OLED has the advantages of no backlight, high contrast, low power consumption, and easy dimming. Therefore, OLED displays must have their own characteristics in design and manufacturing in order to inevitably occur in appearance.
The Renzhijia website was founded in 1995 as the first solution.
Renzhe Technology OLED products use the latest imported raw materials and have outstanding advantages such as lightness, high resolution, and high quality, which are important symbols of product quality and performance. At the same time, it also has strong color saturation and anti touch properties, which can solve the problem of static image flicker at any time in a short period of time.
Sincere friend, if you are not familiar with OLED display products, please read them carefully.
Direct insertion LED beads, LED positive and negative electrodes: This is a common application field, and if you understand OLED display products, you may not have a choice, and sometimes you need a natural solution. OLED display is a common display technology. Its main function is semiconductor LED (LED). LED is a semiconductor solid light-emitting device, which can directly convert electricity into light. The heart of an LED is a semiconductor chip, one end of which is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, making the entire chip encapsulated in epoxy resin. A semiconductor chip consists of two parts, one is a P-type semiconductor in which holes dominate, and the other is an N-type semiconductor in which electrons dominate. But when these two semiconductors are connected, a P-N junction is formed between them. When an electric current passes through a wire and acts on this chip, electrons are pushed towards the P region, where they recombine with holes and emit energy in the form of photons. This is the principle of LED luminescence. The wavelength of light, also known as the color of light, is determined by the material that forms the P-N junction.
LED color change: There are yellow, green, and blue colors, and each color of LED light can be achieved through single or double combination to achieve single or three color LED. For example, small yellow light, blue light, emerald green light, white light, and so on.
The indoor LED display screen has the same appearance as the irregular 3528, and each pixel can demonstrate personalized and systematic characteristics. Special control methods, such as full screen and triple flip.
LED display screen is the abbreviation of light emitting diode. Its basic unit is a LED.
In this case, the LED display screen can be arranged arbitrarily and bent arbitrarily.
The normal working current of the LED display screen is 20mA. Due to excessive strong current, faults and backflow phenomena occur between internal circuits, causing the entire LED display screen to suddenly darken
