Electronic displays refers to information display devices that use electronic technology to transform imperceptible signals into perceptible signals. Their characteristics include small-space occupancy, flexible display format, and simultaneously displaying a variety of information. Common electriconic displays are as follows: cathode-ray tube (CRT), liquid crystal, field luminescence, light emitting diode, plasma display.
As one of the most advanced technology, optoelectronic technology plays an indispensable role in promoting technological transformation of traditional industries, the development of emerging industries and the adjustment and optimization of industrial structure. Optoelectronic technology has the characteristics of precision, accuracy, speed and efficiency. Optoelectronics has been applied in automobile, aviation, aerospace, communications, microelectronics industry.
