the influence of complex temperature on full-color led display panel is very critical of environmental temperature. in theory, it works best at room temperature of about 25 degrees celsius. but in fact, the ambient temperature of outdoor full-color led display is quite complex in application. the highest temperature in summer may be above 60 degrees c, and the lowest temperature in winter may be below – 20 degrees c. led, ic work efficiency and performance are inconsistent, brightness is inconsistent, the overall display of the screen also naturally changed. under different temperature conditions, the attenuation and decline of the brightness of red, green and blue lamps are different. at 25 c, the white balance is normal, but at 60 c, the brightness of the three color leds decreases somewhat, and their attenuation values are inconsistent, so the whole screen brightness decreases and biases. the quality of the whole screen will be improved. it will drop.
and what about ic, the working temperature range of ic is – 40 c – 85 c. because of the high temperature outside, the temperature inside the box rises. if the temperature inside the box exceeds 85 c, the ic will work unsteadily because of the high temperature, or because of the different temperature drift, the current between channels or the difference between sheets will be too large, which will lead to the screen. is striving to make a lot of improvements in design and technology, which can effectively control the influence of external environment temperature on the final effect of the display screen, and make full-color led display screen display perfectly under various complex conditions as far as possible.
the key factors of box design will increase, which will lead to poor image quality. good ventilation and heat dissipation design is an indispensable index for box design. the importance of power supply in a full-color led display system is also an important link affecting quality. because the power supply has different working stability, output voltage value and load capacity under different temperature conditions, its support ability directly affects the quality of the screen because it bears the role of logistics support.
because of the different performance and stability, the price of power equipment of different brands and specifications is quite different. we can’t choose it only on the basis of low and medium price, but not on the basis of its performance and quality. a well-known brand can only be recognized by the society through long-term market cultivation. enterprises regard brand as their life, and will never easily hurt their brand image for short-term benefits. however, xincaichen is a high-tech enterprise integrating scientific research, development, production and engineering. naturally well aware of the importance of brand, therefore, the choice of brand, quality assurance is very helpful.
