汉英对照:
Chinese-English Translation:

曲面电视指屏幕呈有一定弧度,并带有一定的曲率的电视。其原理主要是采用柔性或可弯曲的屏幕,采用贴合人类眼球的弧度,从而造就出与传统电视不同的临场感和包围感。

Curved TV refers to the TV with a certain curvature and a certain radian on the screen. Its principle is mainly to use flexible or bendable screen, and adopt the radian fitting the human eye, so as to create a sense of presence and surrounding different from traditional TV.

什么是曲率

What is curvature

曲线的曲率(curvature)就是针对曲线上某个点的切线方向角对弧长的转动率,通过微分来定义,表明曲线偏离直线的程度。数学上表明曲线在某一点的弯曲程度的数值。曲率越大,表示曲线的弯曲程度越大。

The curvature of a curve is defined by differential according to the rotation rate of the tangent direction angle of a point on the curve to the arc length, indicating the degree of deviation of the curve from the straight line. A numerical value that mathematically indicates the degree of curvature of a curve at a certain point. The greater the curvature, the greater the curvature of the curve.

曲率的最佳标准

The best standard of curvature

目前业界对于曲面电视的曲率,也就是屏幕弧度没有统一标准,各大电视制造企业的产品曲率也各不相同。据三星电子映像显示事业部设计团队首席设计师 Koung-won Park 介绍,他们先后调查了韩国、美国和欧洲各个国家的家庭环境,仔细分析了包括沙发尺寸、观看姿势、以及电视与沙发间距离等重要的数据。最终,他们发现用户在家中的平均观影距离在 3.5-4 米之间。在这段距离内,4200R(曲面半径 4.2 米)正是最佳的曲率。

At present, there is no unified standard for the curvature of curved surface TV, that is, screen radian, and the product curvature of major TV manufacturers is also different. According to Samsung Electronics, Koung-won Park, chief designer of the division’s design team, they have investigated the family environment of various countries in South Korea, the United States and Europe, and carefully analyzed important data including sofa size, viewing posture, and distance between TV and sofa. Finally, they found that the average viewing distance at home was 3.5-4 meters. In this distance, 4200r (surface radius 4.2m) is the best curvature.

曲面电视的类型

Types of curved surface TV

LED 曲面电视的曲屏是将通过开模将平面压成一定的弧度,属于将平面的物理属性外力加以改变,并非原始曲屏。所以由于技术等原因限制,看上去会比目前常见的 LED 平板电视更笨重一些。

The curved screen of LED curved surface TV is to press the plane into a certain arc by opening the mold, which belongs to changing the physical properties of the plane by external force, not the original curved screen. Therefore, due to the limitation of technology and other reasons, it looks more cumbersome than the current common LED flat panel TV.

OLED 曲面电视则是基于屏幕柔性,“先天”就能弯能直,屏幕厚度基本是 4 毫米左右吧。但是成本、造价相比普通 LED 电视也会更高,基本上同尺寸的 OLED 电视价格约为 LED 电视的 2-3 倍。

OLED curved surface TV is based on the flexibility of the screen. It can be bent and straight by nature. The thickness of the screen is about 4 mm. But the cost and cost will be higher than ordinary LED TV. Basically, the price of OLED TV of the same size is about 2-3 times that of LED TV.

ULED 曲面电视是由海信公司在 LED 基础之上,对其进行技术改进,并广泛用于自家曲面电视和电子医疗显示产品之上的一种显示引擎。ULED 更像是对 LED 的优化改进,而并非颠覆性的创新之作。

Led curved surface TV is a kind of display engine which is improved by Hisense on the basis of LED and widely used in its own curved surface TV and electronic medical display products. Uled is more like the optimization and improvement of LED than the subversive innovation.
