The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a base substrate and a number of pixels arranged in an array on the base substrate. Each pixel comprises a number of sub-pixels. Each sub-pixel comprises a reflection unit located on the base substrate, a first electrode located on the reflection unit, a light-emitting unit located on the first electrode, and a second electrode located on the light-emitting unit. In each pixel, the structure of the light-emitting unit of each sub-pixel is the same, and the length of the micro-cavity corresponding to each sub-pixel is different. The micro-cavity length is the distance between the side, which is away from the base substrate, of each reflection unit and the side, which isnear the base substrate, of each second electrode. According to the display panel, a micro-cavity structure is formed between each reflection unit and each second electrode; the length of the micro-cavity corresponding to each sub-pixel in each pixel is different; light modulation of a single sub-pixel is realized; and the colour gamut and the brightness of the display panel are improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] At present, micro-displays have a broad market application space, especially suitable for helmet-mounted displays, stereoscopic display mirrors, and glasses-type displays. Image information, which has very important military value in military applications such as national defense, aviation, aerospace and even individual combat. [0003] There are many types of microdisplays, among which, silicon-based organic light-emitting diode (Organic Light-EmittingDiode, OLED) microdisplays are at the intersection of microelectronics technology and optoelectronics technology, involving a wide range of content, including optoelectronics, microelectronics, The field of electronic informatics and optics is a multidisciplinary research field involving physics, chemistry, materials science and electronic...
