The three domestic giants collectively develop LTPO drive backplane technology

Recently, several major domestic flexible AMOLED panel production lines, Visionox, BOE, and TCL have successively produced their own AMOLED products, and announced the mass production or launch of their own LTPO backplane technology AMOLED products, accelerating domestic production of LTPO backplane technology. kicked off.

LTPO screen technology. The full name of LTPO technology is Low Temperature Polycrystalline Oxide. Most of the previous mobile devices with OLED screens used LTPS TFT (low temperature polysilicon thin film transistor) backplane technology. It has the advantages of high resolution, high response speed, high brightness, and high aperture ratio. 

Despite its popularity, LTPS technology also has some drawbacks, such as higher production costs and higher power consumption. This technology can adaptively adjust the refresh rate of the OLED screen, support dynamic low-frequency driving and low-power energy-saving technology, and relatively completely overcome the problem of OLED "ghost or afterimage" burn-in damage, while also significantly reducing AMOLED displays. power consumption. 

After several years of improvement, the localization of LTPO backplane technology will enhance the market competitiveness of domestic terminal brands.
