Abstract

The invention discloses a display panel, a display device and a preparation method of the display panel. The display panel includes: a driving backplane, a light-emitting diode array layer located on the driving backplane, and the light-emitting diode array layer includes a plurality of light-emitting diodes. The barrier wall arranged between adjacent light emitting diodes and the light conversion film arranged on the side of the light emitting diode array layer away from the driving backplane, the light conversion film includes a variety of primary color units, and each of the primary color units is isolated by a light blocking column , each primary color unit corresponds to a light-emitting diode, and the light emitted by the light-emitting diode array layer can be mixed into white light in the light conversion film; wherein, hollow cavities are distributed in the light conversion film. According to the display panel of the embodiment of the present invention, while achieving colorization, light leakage from light emitting diodes can be reduced, and light utilization efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing the display panel. Background technique [0002] The Micro-Light Emitting Diode (Micro-LED) technology refers to a technology that realizes light-emitting display by using a highly-integrated tiny light-emitting diode array as a pixel on a backplane. At present, Micro-LED technology has gradually become a research hotspot, and the industry expects high-quality Micro-LED products to enter the market. High-quality Micro-LED products will have a huge impact on existing display products such as Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) on the market. [0003] However, in the existing Micro-LED color display, there is still light leakage when the light emitted by the light-emitting diode is emitted to the color filter, resulting in low light utilization efficiency of the Micro-LED display...
