Laser display technology is the fourth generation of display technology after black and white display, color display, digital display, with panchromatic range, high brightness, extreme hd, true 3D and other subversive advantages.
However, the use of projected tri-colour lasaer pointer has limited the use of laser displays in tablet applications such as mobile phones. It is the key to develop the flat panel laser display to use the red, green and blue micro-nano laser as a single pixel and to construct the panchromatic laser array with active luminescence as the display panel.
Chemical research institute of Chinese academy of sciences key laboratory of photochemical yong-sheng zhao, a researcher at the group of researchers for many years has been committed to organic micronano laser materials and device research, in organic micro cavity structure of controllable assembling, organic micronano laser excited state of material process, and organic flexible micronano laser array and so on to carry out the research work of the system.
Recently, researchers give full play to the advantages of organic materials in solution processing aspect, use inkjet printing precision is constructed of red, green and blue micronano laser array as a display panel, implements the active light emitting laser display, solve the current laser projection display cannot be used in mobile phones, tablet, wearable devices, etc.
Each pixel on the resulting panel is composed of three separate red, green and blue lasers. The far-field image shows that the pixels prepared in this way have good color mixing effect and the color gamut coverage exceeds 45% of the standard RGB space. The digital display of three primary colors is realized on a 3×5 array panel, and various other colors can be obtained through color mixing. In addition to Numbers, the panel can also achieve all letters of mixed color display. Furthermore, selecting a larger array panel can dynamically display more complex patterns. Using this active luminous laser panel can also realize the dynamic display of patterns, for information rolling broadcast, video broadcast, etc. This work provides a feasible solution for the development of high performance and easily machined flat panel laser display and lighting devices
