量子点电视优缺点有哪些?与OLED电视有什么不同?

  从智能手机、平板等小型显示设备,到投影仪、智能电视、广告显示屏、影院等大型显示设备,都和显示技术有着紧密的联系。显示技术是支撑彩电业发展创新的核心,对于彩电厂商来说,显示技术的选择关乎企业存亡。以发展历程来看,显示技术经历了厚到薄、重到轻、黑白到彩色、普清到4K的过程。伴随着信息爆炸式增长,人们对显示器的要求不再局限于简单的文字和图片,而是需要获取更多有着丰富色彩表现力的图像和视频文件。

  灰度、成本和寿命方面:量子点电视更有优势,因为OLED采用的是PWM或者DC调光方式。当面板的色数达到10bit,也就是1024级的时候,要想像液晶分子那样精细的控制转向,就比较困难了。同时,OLED采用的蓝色子像素的寿命有限,面板工艺比量子点更加复杂,所以良品率低,这在前面已经谈及,不多加赘述。
