How to make LED touch display more energy-saving and environmentally friendly?
Posted by sere on January 11th, 2021
Green environmental protection has become a major theme of the modern era. Society is progressing, but environmental pollution is also expanding. Therefore, humans must protect our homes. Nowadays, all walks of life are also advocating the manufacture of green and environmentally friendly products. Products, how can LED companies develop and design LED touch displays that do not produce light pollution and waste electrical energy? This has become an important product performance that manufacturers must solve.
LED touch display screens have been widely used in various street corners of the city and have become a unique symbol to enhance the image of the city. However, while beautifying the image of the city, the strong light on the screen has also caused certain negatives to the night life of urban residents. influences. Although the LED industry is a "light-making" industry, and the touch display "light-producing" is understandable, it has become a new type of pollution "light pollution" as measured by the city's environmental pollution indicators. Therefore, as a company, it should pay attention to the problem of "light pollution" in production and control the brightness setting.
The first control method: use an adjustment system that can automatically adjust the brightness.
According to day and night, in different locations and time periods, a slight change in the brightness of the touch display screen will have a great effect. If the playback brightness of the LED touch display is greater than 50% of the ambient brightness, we will obviously feel discomfort in the eyes, which will cause "light pollution".
Then we can collect the ambient brightness at any time through the outdoor brightness collection system, and use the touch display control system to receive the system data and automatically convert it into the brightness suitable for the environment through the software to broadcast the picture.
The second control method: multi-level gray correction technology.
Ordinary LED touch display systems use 18bit color touch display levels, so in some low grayscale and excessive color, the color will be displayed very bluntly, so it will cause the color light to not adapt. The new LED large-screen control system uses a 14-bit color touch display level, which greatly improves the hardness of the color overlying, so that people feel the color soft when watching, and avoid people's discomfort to light.
In terms of power consumption, although the luminescent material used in the LED touch display itself is energy-saving, some applications need to be used in applications with a large touch display area. Due to long-term use, the overall power consumption is still relatively large because of the brightness required It will be relatively high. Under the effect of these comprehensive factors, the power consumption of the touch display screen is quite astonishing, so the electricity bills borne by advertising owners will also increase geometrically. Therefore, LED touch display manufacturers can save energy through the following 5 points:
(1) By using high-efficiency LEDs, the light-emitting chip does not cut corners;
(2) Adopting high-efficiency switching power supply, greatly improving power conversion efficiency;
(3) Carry out excellent heat dissipation design of the screen to reduce the power consumption of the fan;
(4) Design a scientific overall circuit plan to reduce the power consumption of internal circuits;
(5) According to changes in the external environment, the brightness of the outdoor touch display is automatically adjusted to achieve the effect of energy saving and emission reduction.
