As Samsung and Apple become more interested in using old panels in future handsets, it is expected that approximately 45% of handsets sold worldwide next year will have old screens.
New report Is called Almost half of the phones that will be launched in 2022 have old screens, and this shows the growing popularity of this technology in the smartphone market.
According to the report, 39.8% of all handsets sold this year have an old panel. On the other hand, 45% of the total handsets sold next year are expected to have this type of display. The report, compiled by TrendForce, states that one of the main reasons for the increase in the market share of devices equipped with old panels is the interest of major manufacturers such as Apple and Samsung in the wider use of old technology.
Currently, the display driver IC power supply for old panels can not meet all market demand, and the report adds that these chips are relatively larger than other chips, so fewer can be produced in each wafer.
Most display drivers use 40nm to 28nm processes for the IC. Currently, only a few foundries, such as Taiwanese semiconductor maker TSMC, Samsung, UMC and GlobalFoundries, can produce OLED panel display driver ICs.
Of all the chip companies, however, only TSMC, Samsung, and UMC have enough wafers to produce display drivers. Meanwhile, other foundries are working to develop the necessary technologies to begin mass production. Another notable factor that affects the production process is that different manufacturers require different specifications for display driver ICs.
