③成本、售价较高。目前它也正朝扩展可视角、降低惰性、降低价格、提高投影光源(灯泡)寿命等方面发展,并已取得了可喜进展,其最新技术进展主要有:a.采用平坦化技术增加光的适应范围,加快透光速度,响应时间由16ms降低到12ms,减少了快速运动图像的拖尾现象,使图像更清晰; ③ cost, higher prices. At present, it is also moving towards expanding its viewing angle, reducing inertness, lowering prices and improving the life of projection light bulbs (light bulbs), and has made gratifying progress. The latest technological advances are as follows: a. Adopting the planarization technology to increase the light adaptation Range, speed up the light transmission speed, response time reduced from 16ms to 12ms, reducing the trailing phenomenon of fast moving images, the image clearer;
