Unbeknownst to me, the Tokyo Olympics are right around the corner. So a friend asked, can the Olympic concept be promoted? At least in terms of past experience, participate carefully and mainly watch dramas.
It's useless to think twice. The stock market has its own rules of operation. The apparent correlation between the Olympics and the stock market also complements logical causes and effects. However, if you want to choose a theme in the stock market to cheer for the Olympics, then mini LED has both its own logic and can keep up with current events.
The main application of mini LED is in the field of display, such as TV panels, mobile phone screens, computer screens, etc.
Mini LED is still in the early stages of development. To discuss its investment logic, we need to first understand the two mainstream technologies currently mature: LCD (liquid crystal display) and OLED (organic light-emitting diode).
Note: AMOLED is one type of OLED
The difference between the two display principles is that an LCD requires white light (usually an LED) as a backlight source and a red, green, and blue filter to achieve color display; while an OLED has a tiny red, green, and blue light emitting unit that emits different colors independently at different voltages, and a large number of light emitting units directly form a screen.
OLEDs are more technologically advanced and lead LCDs in terms of color, thickness, power consumption, and service life. However, this does not mean that LCD has completely failed, because the commercialization of OLED faces 2 problems. First, large OLED screens are difficult to mass-produce, and their application is temporarily limited to small screens such as mobile phones and smartwatches; second, because OLEDs work at high temperatures for a long time, they can...
