First, adopt an adjustment system that can automatically adjust the brightness. According to day and night, under different location environments and time periods, a slight change in the brightness of the display will have a great effect. If the playback brightness of the LED transparent screen is greater than 50% of the ambient brightness, we will obviously feel eye discomfort, which will cause "light pollution".
Then we can collect the ambient brightness at any time through the outdoor brightness acquisition system, and use the display control system to broadcast the screen by receiving system data and automatically converting it into a brightness suitable for the environment through software. Second, multi-level grayscale correction technology. Ordinary LED display system adopts 18bit color display level, so that in some low grayscale and excessive color, the color will be displayed very stiff, so it will cause the discomfort of colored light.
The new LED large screen control system adopts 14bit color display level, which greatly improves the hardness of the color transition, making people feel the color is soft when watching, and avoiding people's uncomfortable feeling to the light. In terms of power consumption, although the luminescent materials used by the LED display itself are energy-saving, some of them need to be applied to occasions with a large display area. If they are used for a long time, the overall power consumption is still relatively large because of the brightness required. It will be relatively high. Under the influence of these comprehensive factors, the power consumption of LED flexible screens is quite astonishing, so the electricity bills borne by advertising owners will also increase geometrically. There are several ways to save energy for LED displays? 1. By using high-efficiency LEDs, the light-emitting chips do not cut corners; 2. Using high-efficiency switching power supplies to greatly improve power conversion efficiency; Fan power consumption; 4. Design a scientific overall circuit scheme to reduce power consumption of internal circuits; .
