Recently, TCL Huaxing showed a new 75 inch 8K 120Hz mled TV panel on Sid 2022, this is the world's first LCD display with ultra-high resolution 8K and ultra-high refresh rate 120Hz produced by 4mask process** The panel adopts the a-Si 4mask backplane technology pioneered by TCL Huaxing in the industry. Officials say it can not only ensure the perfect image quality, but also greatly reduce the process cost, with ultra-high cost performance.
In terms of parameters, the screen is equipped with the mini LED backlight of TCL Huaxing's original glass based active backlight partition driving technology, which makes it comparable to the image quality performance of OLED, with a color gamut value of 103%, a peak brightness of 1000nits and a contrast of 1000000:1**
TCL Huaxing said that compared with 4K and below resolution products, 8K products face the biggest bottleneck is the screen charging rate. In order to improve the charging rate of the screen, the traditional hg2d technology needs to double the number of data drive lines to improve the charging time.
The new generation TCL Huaxing 8K 1g1d adopts four technologies: high penetration HVA technology, high charging 1g1d technology, high frequency CSPI technology and high contrast mled Obsidian technology.
Specifically, 8K high penetration HVA technology is equipped with the development of high penetration devices and materials, which can achieve the same display brightness at a lower backlight brightness and achieve energy-saving effect**
The scrambling design of 8K high-frequency CSPI technology can effectively disrupt the data and reduce EMI. By reducing the low quiescent current of the buffer amplifier, it can reduce the power consumption of the buffer amplifier and reduce the temperature of the driving IC.
