Abstract 
With the rapid development of photoelectric technology, display technology is also constantly improving, the pursuit of higher color saturation, wider color gamut and higher brightness. Quantum dots, as a new type of nanomaterials, show great potential and advantages in photoelectric display technology. This paper aims to discuss the design and application of quantum dots in photoelectric display technology, analyze the design principle, application advantages and challenges of quantum dots in display technology from the characteristics of quantum dots, and look forward to its future development trend. Quantum dots are nanomaterials with special optical and electrical properties, which are in the nanometer scale, have tunable luminous wavelengths and high quantum efficiency. These unique properties make quantum dots have a wide application prospect in photoelectric display technology. By applying quantum dots to display devices, high color saturation, wide color gamut and high brightness display effects can be achieved, bringing consumers a more realistic visual experience. In the photoelectric display technology, the design of quantum dots mainly involves its size, shape and surface modification. By precisely controlling the size of the quantum dots, the luminescence wavelength can be tuned to meet the needs of display devices for different colors of light. At the same time, the shape and surface modification of quantum dots will also affect their optical and electrical properties, which will affect the performance of display devices. Therefore, in the design process of quantum dots, various factors need to be considered comprehensively to achieve the best display effect. The application of quantum dots in photoelectric display technology mainly includes quantum dot backlight, quantum dot LED (QLED) display technology and quantum dot filter. In a quantum dot backlight, quantum dots are used to convert the light emitted by a blue LED into a broad spectrum of white light, thereby improving the accuracy and brightness of the colors displayed. In QLED display technology, quantum dots, as a luminous layer, have self-luminous characteristics, do not require backlight, and can achieve higher contrast and wider color gamut. Quantum dot filters, on the other hand, use the properties of quantum dots to absorb specific wavelengths of light to convert the color of light, which can be used to create warmer, more natural light sources. The application of quantum dots in photoelectric display technology brings many advantages, such as high color saturation, wide color gamut and high brightness. However, there are also some challenges, such as the stability, reliability and production costs of quantum dots. To overcome these challenges, it is necessary to further strengthen the research and development of quantum dots, improve their performance and reduce their cost. Quantum dots have broad application prospects in photoelectric display technology. With the continuous progress of technology and in-depth research, it is believed that quantum dots will bring more innovations and breakthroughs for photoelectric display technology in the future.
