不少家庭在购买彩色电视机时,都喜爱选购直角平面彩电。那么,什么是直角平面彩电?它又有什么优越性呢?采用直角平面(又叫方角平面)自会聚彩色显像管的电视机,叫做直角平面彩色电视机。市场上销售的大多数是21in(54cm)和19 in(49cm)的机型,此外还有17、25、28in等多种规格。直角平面自会聚彩色显像管,其主要特征是荧屏实现了矩形化、平面化和方角化。普通彩显管屏幕玻璃的曲率半径约为1000 mm左右,而直角平面彩显管屏幕玻璃的曲率半径则大于1500mm。换句话说,即屏幕表面几乎接近于平面。另外屏幕的四角呈直角
Many families buy color television sets, they all love to buy rectangular flat color TV. So, what is the right angle plane color TV? What is its superiority? The use of a rectangular plane (also known as square plane) from the convergence of color picture tube TV, called right angle plane color TV sets. Most of the products on the market are 21in (54cm) and 19in (49cm) models, with a variety of specifications such as 17,25,28in. Since the rectangular plane self-convergence color picture tube, the main feature is the screen rectangular, planarization and square corner. Ordinary color display screen tube curvature radius of about 1000 mm, while the right-angle plane color display screen glass curvature radius is greater than 1500mm. In other words, the screen surface is almost flat. In addition, the four corners of the screen are at right angles
