With such advantages, why is it so hard to buy a consumer display now? Because cost-profit requirements are limited. Due to the huge number of Micro LED on a screen, the complexity of the huge transfer technology, and the most difficult factory consistency adjustment, the cost of Micro LED is still very high, ordinary consumer display users can not afford for the time being. So the current LED display technology, although it claims to be “revolutionary”, is mainly used in large screens, including outdoor large screens, giant flat-screen TVS, and some niche areas of small screens, such as luxury car displays. Because these users are paying for the display.
Multi-chip white LED (MC-LED) is an LED that combines red, blue, and green LED chips to achieve white light. The white light achieved by this method has two remarkable characteristics of high luminous efficiency and flexible regulation. Since multi-chip white LED is directly electroluminescent through each LED chip, there is no Stokes shift energy loss and non-radiative compound loss in phosphor, so its energy loss is small and luminous efficiency is high. In addition, the method uses the light emitted by the LED chip of three primary colors to mix to achieve white light, so the luminous characteristics such as color and color temperature can be controlled by adjusting the size of the current of the LED chip, which has certain flexibility in practical application.
The bonding interface such as the substrate must be kept clean and pollution-free. If the conductive silver paste is used, it is also necessary to prevent silver migration, so as not to increase the conductive resistance and form additional leakage channels. The most likely problem of conductive adhesive bonding is poor bonding, resulting in the cracking of conductive adhesive and chip or lead frame, and eventually LED working instability, series resistance increase, breakdown voltage increase, and even open circuit. Temperature shock to the device These phenomena will deepen or decrease, and mechanical pressure may return to normal and can be repeated many times.
