What is an indoor high-definition LED screen is defined relative to the "standard definition" commonly used in our TV sets. The division of the two comes first from the video effects that can be seen. Due to the different image quality and bandwidth occupied by channel transmission, digital TV signals are divided into HDTV (high-definition television), SDTV (standard-definition television) and LDTV (general-definition television). In terms of visual effects, HDTV has the highest specification.
In terms of picture quality, the resolution of high-definition LED displays is basically four times that of traditional analog TVs, and the picture clarity and color reproduction are far superior to traditional TVs. For example, when the original standard definition broadcasts a football match, the football field is green, but the high-definition signal will let you see that the green field is composed of green grass. The 16:9 widescreen display also brings a wider visual enjoyment. In terms of audio effects, high-definition TV programs will support Dolby 5.1-channel surround sound, and high-definition video programs will support Dolby 5.1 True HD specifications, which will bring us super shocking listening enjoyment.
