[0080] The electroluminescence laser display panel, the panel including a periodically arranged pixel array, the pixel array electroluminescence laser display panel includes a polymer micromotoischarge as a blank pixel, and an electroluminated micromaine in a spin-coated injection polymer micromotactic structure.

[0081] figure 1 The nature of the distributed Prague mirror used. The ITO-based distributed Prague mirror with high reflectance in the blue zone is DBR1; the ITO-based distributed Prague mirror having high reflectivity in the green spot is DBR2; distribution of ITO based on the red light region The Prague mirror is DBR3. like figure 1 As shown, DBR1, DBR2, and DBR3 have different reflection spectrum, spanning the entire visible region. This facilitates the realization of high-color purity light exits, thereby providing a basis for realizing laser display.

Abstract

The invention discloses an electroluminescent laser display and a construction method thereof. According to the electroluminescent laser display, the display comprises a pixel array which is arranged periodically, and the pixel array comprises a polymer micro-template and an electroluminescent micro-structure; the polymer micro-template is used as a blank pixel, and the electroluminescent micro-structure is located in the polymer micro-template; and the electroluminescent micro-structure comprises an electroluminescent material. Through the combination of the electroluminescent micro-structure and a reflection cavity composed of a high-reflection metal electrode and an ITO-based distributed Bragg reflector, high-purity electroluminescence can be formed, and wide-color-gamut and high-saturation color display can be achieved.

Description

Technical field [0001] The present invention belongs to the field of laser display, and more particularly to an electroluminescence laser display and a construction method thereof. Background technique [0002] Laser display, utilizing high monochrome and high brightness of laser emissions, due to its enabled width, high color saturation and high color contrast, have become revolutionary in the display industry Significance technology. Laser display technology is hindered by the application on portable display devices because it lacks electric pump material capable of covering visible light. Therefore, it is of great significance to develop a pixelated display panel having a laser monochrome and color gamut covered by electroluminescence. An effective strategy is to modulate the emission light of the light-emitting diode of the pixel. So far, the display panel of the light-emitting diode as a pixel point has been widely used, such as mobile phones, computers, television, and so o...
