Industrial-grade LCD screen factory will show you what is the viewing angle of LCD screen?
Regarding the viewing angle of LCD screens, there was an article before that specifically talked about the viewing angle of industrial display screens. This article mainly talks about judging the viewing angle of industrial display screens from three aspects: contrast, grayscale, and color difference. As a professional and reliable industrial display screen manufacturer, Youyi Vision will introduce the viewing angle of LCD screens to you today.
As we all know, the most basic principle of liquid crystal display is that liquid crystal molecules are a unique substance. When light enters them, it will refract. At the same time, liquid crystal molecules have unique electrical properties and can be deflected under the action of electric fields. Once these two characteristics are combined, under the action of polarizers, people can use electric fields to control the brightness of light, down to each pixel, that is, they can control the brightness of each unit, so as to achieve the display effect.
When observing from the center of the screen and from the side, the intensity of light entering the human eye is different. For the same picture, there will be brighter and darker situations, that is, the contrast is different. Combined with the definition of viewing angle, within the contrast range acceptable to the human eye, the viewing angle corresponding to the screen is the viewing angle.
The LCD screen is a backlit display device. The light it emits is provided by the backlight source behind the LCD module, which inevitably leads to the LCD screen having only one optimal viewing angle – looking straight ahead. When viewed from other angles, the backlight source can penetrate the pixels next to it and enter the human eye, causing color distortion. The range without distortion is the viewing angle. The viewing angle of the LCD screen is also divided into horizontal viewing angle and vertical viewing angle. Generally, the horizontal viewing angle is greater than the vertical viewing angle.
At present, as long as the horizontal viewing angle reaches 120 degrees and the vertical viewing angle reaches 140 degrees, the application needs of most users can be met. The latest LCD panels are produced using wide viewing angle technology, which can reach a viewing angle of 140 degrees up and down and 150 degrees left and right, reducing the inconvenience caused by small viewing angles. Of course, this performance cannot be compared with the nearly 180-degree viewing angle of CRT displays, but it is more than enough for most applications.
Hangzhou Zhongyou Touch Display Intelligence is a national high-tech enterprise integrating industrial display screens and touch screen research and development, design, production, sales and service. All industrial displays developed and produced by it meet the requirements of wide viewing angle, 180° wide viewing angle technology, higher light transmittance, release colors at any angle, more realistic pictures, more saturated colors, making your terminal products more competitive.
Common viewing angles of LCD or TFT LCD screens include: narrow viewing angle, wide viewing angle, IPS viewing angle, full viewing angle, etc.
