The development of display technology can be divided into three stages. Take TV as an example.
The first stage, the CRT era of the 20th century: In 1897, the world's first CRT was born. The phosphor on the inner surface of the screen was excited by electron beams to display images, which realized the conversion of electrical signals to light output. With the improvement of technology and technology, the industrialization of CRT technology began in the 1950s, and black-and-white CRT TVs and color CRT TVs became the most important display devices in life. Although CRT production costs are low and limited by picture tubes, CRTs generally can only be 34 inches in size, which cannot meet the increasing demand for large sizes.
The appearance of Mini-LED changed the passive situation of LCD. The addition of Mini-LED backlight technology has greatly improved the performance of LCD and directly competes with OLED in all aspects of non-flexible display performance: Because Mini-LED has local dimming technology, it can dynamically adjust the overall picture. Light can achieve high dynamic contrast and wide color gamut display. Through special packaging structure and technology, the light angle can be increased, the halo effect can be reduced, the terminal can achieve near-zero OD design with a uniform self-mixing effect, and the whole machine can be thin and light. It can achieve the same effect as an OLED display.
Due to other expenses such as depreciation and labor costs, there is still a certain price difference between AMOLED and LCD mobile phone panels: Data from Zhiyan Consulting shows that the yield of AMOLED needs to reach 80% and its cost may be lower than that of LCD. With the increase in yield, Trendforce predicts that the penetration rate of AMOLED mobile phones will rise from 31% in 2019 to 38% in 2021, and the penetration rate of AMOLED mobile phones is expected to exceed 50% in 2025.
