Embodiment Construction

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning...

Abstract

The present invention relates to a display device, in which a blue light-emitting layer and a mixed pixel layer are layered, and the red and green pixel units in the mixed pixel layer can respectively emit red and green light after receiving the blue light emitted by the blue light-emitting layer. Excitation light, while the blue pixel unit is left blank for direct transmission of blue light, so that different colors can be combined on the mixed pixel layer. The blue light-emitting unit in the blue light-emitting layer of the display device has a nanorod array, which forms a blue microLED with electrodes on both sides. Since the nanorod material has little change in luminous efficiency with size changes, it has excellent external quantum efficiency. And the holes and electrons are separated from each other most of the time, so the stability of the display device is high. The display device combines nanorod-shaped blue microLEDs with red and green quantum dot materials, which can improve the utilization rate of blue light and help improve the resolution of the display device, which can meet the resolution and image quality requirements of the next generation of high-end display products. and cost requirements.

Description

technical field [0001] The invention relates to the technical field of light emitting display, in particular to a display device. Background technique [0002] Micro LED (micro LED) is a new generation of display technology, which has higher brightness and better luminous efficiency than traditional OLED technology, but lower power consumption. In February 2018, Samsung Electronics demonstrated its 146-inch 4K microLED TV - "The Wall" at the 2018 International Consumer Electronics Show (CES) in Las Vegas, USA. Each RGB color sub-pixel of the microLED TV panel is made of microLEDs of the respective color. In high-resolution display technology, as the resolution increases, the number of pixel units is also required to increase several times accordingly. For example, a 4K resolution TV panel is actually composed of 3840×2160 RGB pixel units. That is, it includes about 25 million groups of RGB sub-pixel units. Using the traditional microLEDs mentioned above to make high-resol...
