分析了液晶显示、有机发光二极管显示、量子点发光二极管显示及激光显示这几种主流显示技术的结构及原理, 并从结构、材料、性能、应用领域几方面对它们进行了比较, 最后给出了这几种主流显示技术的最新进展。LCD显示经过多年发展, 技术成熟, 成本低廉, 仍然在显示技术中占据着重要地位。OLED显示具有响应速度快, 轻薄, 可柔性化等优点, 已成为目前主流显示技术, 有取代LCD显示之势。QLED显示技术凭借其优越的发光性能正在朝着自发光显示的目标不断前进。激光显示具有亮度高、色域宽、寿命长、功耗低、节能、环保等优势, 也将成为下一代高端显示的主流, 实现高保真超大屏幕显示。

The structure and principle of liquid crystal display (LCD), Organic Light Emitting Diode (OLED) display, Quantum Dot Light Emitting Diodes (QLED) display and laser display are analyzed. The structure, material, performance and application fields about these display technologies are compared. The new developments of these display technologies are given. Due to the mature technology and low cost, LCD display still plays an important role in the display industry. Due to the advantages of fast response, lightweight and flexibility, OLED display has become the mainstream technology of current display, and tends to displace LCD display. With its superior luminescence performance, QLED display is developing towards the direction of self-emissive display. Because the Laser display has the advantages of high color saturation, extended color gamut, long life, low power consumption, energy-saving, and environment-friendly, it is considered to be the mainstream technology of next generation high-end displays, and can be realized as the super large screen display with high fidelity.
