With the rapid development of Outdoor LED Digital Display, LED display manufacturers have also sprung up, so how do you choose the Outdoor LED Digital Display products suitable for your project?
How to choose Outdoor LED Digital Display according to brightness?
What types of Outdoor LED Digital Displays are there?
What are the important parameters of Outdoor LED Digital Display?
Since the Outdoor LED Digital Display will be exposed to direct sunlight, the sunlight reflected by the screen will affect the playback effect. Sometimes if the brightness of the Outdoor LED Digital Display is too low, the content of the screen will be completely invisible. Then the brightness of the Outdoor LED Digital Display How much does it need to be so that it is not affected by direct sunlight? For example, the brightness of the screen when the sunlight hits the screen and then reflects is about 5000CD/square or more, so the brightness of the screen should reach 6000CD/square when there is direct sunlight. The above will not affect the playback effect of sunlight. At present, most of the manufacturers of Outdoor LED Digital Display have met this requirement.
According to the color of the LED used, Outdoor LED Digital Display can be divided into single primary color, dual primary color and full color screen. The single-color LED display can be used as a text display, each pixel uses a single-color LED, most of which are red; the dual-color LED display can be used as a graphic display, each pixel is composed of red and green LED tubes, It can display three colors of red, green and yellow; the full-color LED display can be used as a video display, each pixel is composed of three LED tubes of red, green and blue, and the display color is delicate.
1. Dot Spacing
When choosing Outdoor LED Digital Display, the dot pitch of the display should also be selected according to the distance of the audience. Outdoor LED Digital Display is generally divided into P4, P6, P8, P10, P16 and so on according to the dot pitch. Generally, it can be estimated according to the simplified formula "best viewing distance = dot spacing/(0.3~0.8)". For example, with a P16 display screen and a dot spacing of 16mm, the best viewing distance is 20-54 meters.
2. Grayscale
Grayscale is an important indicator to measure the display effect of Outdoor LED Digital Display. Grayscale is determined by the number of analog-to-digital conversion bits when supported by other supporting hardware. The mainstream is 8-bit, 10-bit and 16-bit. The digital conversion corresponds to 256 kinds of brightness changes, that is, 256 levels of grayscale, and there are 256×256×256=16777216 kinds of color changes, which are commonly called 16M colors; 10-bit analog-to-digital conversion corresponds to 1024 kinds of brightness changes, that is, 1024 levels of grayscale , a total of 1024×1024×1024=1073741824 kinds of color changes, that is, 1.07 billion colors commonly referred to. The higher the gray level, the better the display effect.
