摘　　要：随着消费需求的升级和显示技术的提升,电视正在向着更高分辨率方向发展,4K电视逐渐普及,8K电视紧跟其后,将成为行业未来发展趋势。8K超高清电视即像素数目达7 680×4 320的电视,其像素数目是全高清电视的16倍,能够提供清晰度更高、更细腻的画质效果,因此,日本计划在2020年东京奥运会全面落实8K直播转播,2022年的北京冬奥会,8K也会是崭新的直播标准。目前支持8K信号的标准协议有DP1.4和HDMI2.1,刚发布不久,在此之前市面上销售的8K电视大多是4K输入的"伪8K电视",它是将4K图像上变换到8K来显示的,严格来说并非真正的8K超高清电视。本文介绍一种全新的双通道8K电视,包含4K通道和8K通道,其中8K通道实现了"8K信源-8K画质处理-8K像素驱动"的全程8K处理(真8K显示),给体验者以完美的视觉享受,特别是在大型直播现场、医疗显示、安防监控等方面,带来超高清的显示效果。With the upgrading of consumer demand and the improvement of display technology,TV is developing towards higher resolution direction. 4 K TV is becoming more and more popular. 8 K TV will follow the trend and become the future development trend of the industry. 8 K UHD TV is up to 7 680 × 4 320 pixels at the TV,the number of pixels is 16 times the full HD TV,can provide a higher resolution,more delicate picture,therefore,Japan plans to fully implement 8 K live broadcast in the Tokyo Olympic Games in 2020,and the Beijing Winter Olympics in 2022 will also be broadcast with a brand new 8 K live broadcast. At present,the standard protocols supporting 8 K signals are DP1. 4 and HDMI2. 1. They just released soon. Before that,most of the 8 K televisions sold on the market were ＂ pseudo 8 K TV＂ with 4 K input,the 8 K display was obtained by enlarging 4 K images,and strictly speaking,it is not the real 8 K HD TV. This paper introduces a new dual channel 8 K TV,which includes 4 K channel and8 K channel. The 8 K channel is true 8 K display,providing perfect visual enjoyment,especially in the large live live,medical display,security monitoring and other aspects,which brings super high definition display effect.
